For Ariel Reich

Every SF writer should be lucky enough to have a good friend who is both
a Ph.D. in physics and a lawyer specializing in intellectual property.

Thanks, Ari, for helping me launch the Argo on its relativistic flight,
work out the Lagrange points for the Quintaglio system, design a
chemical structure for a new form of matter, and prosecute an
extraterrestrial defendant.

**ALPHA DRACONIS**

There would be hell to pay.

The gravity had already been bled off, and Keith Lansing was now
floating in zero-g.  Normally he found that experience calming, but not
today.  Today, he exhaled wearily and shook his head.  The damage to
Starplex would cost billions to repair.  And how many Commonwealth
citizens were dead?  Well, that would come out in the eventual
inquest--something he wasn't looking forward to one bit.

All the amazing things they had discovered, including .first contact
with the darmats, could still end up being overshadowed by politics--or
even interstellar war.

Keith touched the green GO button on the console in front of him.

There was a banging sound, conducted through the glassteel of the hull,
as his travel pod disengaged from the access ring on the rear wall of
the docking bay.  The entire run was preprogrammed into the pod's
computer: exiting Starplex's docks, flying over to the shortcut,
entering it, exiting at the periphery of the Tau Ceti system, and moving
into one of the docking bays on Grand Central, the United Nations space
station that controlled traffic through the shortcut closest to Earth.

And, because it was all preprogrammed, Keith had nothing to do during
the journey but reflect on everything that had happened.

He didn't appreciate it at the time, but that, in itself, was a miracle.

Traveling halfway across the galaxy in the blink of an eye had become
routine.  It was a far cry from the excitement of eighteen years ago,
when Keith had been on hand for the discovery of the shortcut network--a
vast array of apparently artificial gateways that permeated the galaxy,
allowing instantaneous point-to-point transfer.

Back then, Keith had called the whole thing magic.  After all, it had
taken all of Earth's resources twenty years earlier to establish the New
Beijing colony on Tau Ceti 1, just 11.8 light-years from Sol, and New
New York on Epsilon Indi III, only 11.2 light-years away.  But now
humans routinely popped from one side of the galaxy to the other.

And not just humans.  Although the shortcut builders had never been
found, there were other forms of intelligent life in the Milky Way,
including the Waldahudin and the Ibs, who, together with Earth's humans
and dolphins, had established the Commonwealth of Planets eleven years
ago.

Keith 's pod reached the edge of docking bay twelve and moved out into
space.  The pod was a transparent bubble, designed to keep one person
alive for a couple of hours.

Around its equator was a thick white band containing life-support
equipment and maneuvering thrusters.  Keith turned and looked back at
the mothership he was leaving behind.

The docking bay was on the rim of Starplex's great central disk As the
podpulled farther away, Keith could see the interlocking
triangularhabitat modules, four on top and four more on the bottom.

Christ, thought Keith as he looked at his ship.  Jesus Christ.  The
windows in the four lower habitat modules were all dark.  The central
disk was crisscrossed with hairline laser scorches.

As his pod moved downward, he saw stars through the gaping circular hole
in the disk where a cylinder ten decks thick had been carved out of it.

Hell to pay, thought Keith again.  Bloody hell to pay.

He turned around and looked forward, out the curving bubble.  He'd long
ago given up scanning the heavens for any sign of a shortcut.  They were
invisible, infinitesimal points until something touched them, --he
glanced at his console--as his pod was going to do in forty seconds.  Then
they swelled up to swallow whatever was coming through.

He'd be on Grand Central for perhaps eight hours, long enough to report
to Premier Petra Kenyatta about the attack on Starplex.  Then he'd pop
back here.  Hopefully by that time, Jag and Longbottle would have news
about the other big problem they were facing.

The pod's maneuvering thrusters fired in a complex pattern.  To exit the
network back at Tau Ceti, he'd have to enter the local shortcut from
above and behind.  The stars moved as the pod modified its course to the
proper angle, and then---and then it touched the point.  Through the
transparent hull, Keith saw the fiery purple discontinuity between the
two sectors of space pass over the pod, mismatched star-fields fore and
aft.  To the rear, the eerie green light of the region he was leaving,
and up ahead, pink nebulosity--Nebulosity?

That can't be right.  Not at Tau Ceti.

But as the pod completed its passage, there could be no doubt: he'd come
out at the wrong place.  A beautiful rose-colored nebula, like a splayed
six-fingered hand, covered four degrees of sky.  Keith wheeled around,
looking out in all directions.  He knew well the constellations visible
from Tau Ceti --slightly skewed versions of the same ones seen from
Earth, including Boetes, which contained bright Arcturus and Sol itself.

But these were unfamiliar stars.

Keith felt adrenaline pumping.  New sectors of space were being opened
at a great rate, as new exits became valid choices on the shortcut
network.  Clearly, this was a shortcut that had only just come on-line,
making more narrow the acceptable angles of approach to reach Tau Ceti.

No need to panic, thought Keith.  He could get to his intended
destination easily enough.  He'd just have to reenter the shortcut on a
slightly different path, making sure he didn't vary at all from the
mathematical center of the cone of acceptable angles for Grand Central
Station.

Still--another new sector. That made five in the last year.  God, he
thought, it was too bad they'd had to cannibalize half of Starplex's
planned sister ship for parts; they could use another exploration
mothership immediately if things kept on like this.

Keith checked his flight recorder, making sure he'd be able to return to
this place.  The instruments seemed to be operating perfectly.  His
first instinct was to explore, discovering whatever this new sector had
to offer, but a travel pod was designed only for quick journeys through
shortcuts.

Besides, Keith had a meeting to get to and--he glanced at his watch
implant --onlyforty-five minutes before it would begin.  He looked down
at his control panel and keyed in instructions for another pass through
the shortcut network.

He then checked the settings that had brought him here--and frowned.

Why, he had come through at precisely the right angle for Tau Ceti.

He'd never heard of a shortcut transfer going wrong before, but .  ..

When he looked up, the starship was there.

It was shaped like a dragon, with a long, serpentine central hull and
vast swept-back extensions that looked like wings.  The entire thing
consisted of curves and smooth edges, and there was no detailing on its
robin's-egg-blue surface, no sign of seams or windows or vents, no
obvious engines.  The whole thing must have been glowing, since there
were no stars nearby to illuminate it, and no shadows fell across any
part of its surface.  Keith had thought Starplex beautiful before its
recent battle scars, but it had still always seemed manufactured and
functional.  This alien ship, though, was art.

The dragon ship was moving directly toward Keith's pod.

The readout on his console said it was almost a kilometer long.  Keith
grabbed the pod's joystick, wanting to get out of the approaching ship's
path, but suddenly the dragon came to a dead stop relative to the pod,
fifty meters ahead.

Keith's heart was pounding.  Whenever a new shortcut came on-line,
Starplex's first job was to look for any signs of whatever intelligence
had activated the shortcut by passing through it for the first time.

But here, in a one-person travel pod, he lacked the signaling equipment
and computing power needed to even attempt communications.

Besides, there had been no sign of the ship when he'd surveyed the sky
moments ago.  Any vessel that could move that quickly then stop dead in
space had to be the product of very advanced technology.  Keith was in
over his head.  He needed if not all of Starplex, at least one of the
diplomatic craft it carried in its docking bays.  He tapped the key that
should have started his pod back toward the shortcut.

But nothing happened.  No--that wasn't quite right.

Craning his neck, Keith could see his pod's maneuvering thrusters firing
on the outside of the ring around the habitat bubble.  And yet the pod
wasn't moving at all; the background stars were rock steady.

Something had to be holding him in place, but if it was a tractor beam,
it was the gentlest one he'd ever encountered.  A travel pod was
fragile; a conventional tractor would have made its glassteel hull groan
at the seams.

Keith looked again at the beautiful ship, and as he watched a--a docking
bay, it must have been--appeared in its side, beneath one of the curving
wings.  There had been no sign of a space door moving away to reveal it.

The opening simply wasn't there one instant, and the next instant, it
was --a cube-shaped hollow in the belly of the dragon.

Keith found his pod moving now in the opposite direction he was telling
it to go, moving toward the alien vessel.

Despite himself, he was starting to panic.  He was all in favor of first
contact, but preferred it on more equal terms.

Besides, he had a wife to get back to, a son away at university, a life
he very much wanted to continue living.

The pod floated into the bay, and Keith saw a wall.  wink into existence
behind him, closing the cube off from space.

The interior was lit from all six sides.  The pod was presumably still
being held by the tractor beam--no one would pull an object inside just
to let it crash into the far wall under its own inertia.  But nowhere
could Keith see a beam emitter.

As the pod continued its journey, Keith tried to think rationally.  He
had entered the shortcut at the right angle to come out at Tau Ceti; no
mistake had been made.  And yet, somehow, he had been--been diverted
here .  . .

Which meant that whoever controlled this interstellar dragon knew more
about the shortcuts than the Commonwealth races did.

And then it hit him.

The realization.

The horrible realization.

Time to pay the toll.

Chapter I

It had been like a gift from the gods: the discovery that the Milky Way
galaxy was permeated by a vast network of artificial shortcuts that
allowed for instantaneous journeys between star systems.  No one knew
who had built the shortcuts, or what their exact purpose was.  Whatever
hugely advanced race created them had left no other trace of its
existence.

Scans made by hyperspace telescopes suggested that there were four
billion separate shortcut exits in our galaxy, or roughly one for every
hundred stars.  The shortcuts were easy to spot in hyperspace: each one
was surrounded by a distinctive sphere of orbiting tachyons.  But of all
those shortcuts, only two dozen appeared to be active.  The others
clearly existed, but there seemed to be no way to move to them.

The closest shortcut to Earth was in the Oort cloud of Tau Ceti.

Through it, ships could jump seventy thousand light-years to Rehbollo,
the Waldahud homeworld.  Or they could jump fifty-three thousand
light-years to Flatland, home of the bizarre Ib race.  But the shortcut
exit that existed near Polaris, for instance, just eight hundred
light-years away, was inaccessible.  It, like almost all the others, was
dormant.

A particular shortcut would not work as an exit for ships arriving from
other shortcuts until it had first been used locally as an entrance.

Thus, the Tau Ceti shortcut had not been a valid exit choice for other
races until the UN sent a probe through it, eighteen years ago, back in
2076.  Three weeks later, a Waldahud starship popped out of that same
shortcut--and suddenly humans and dolphins were not alone.

Many speculated that-this was how the shortcut network had been designed
to work: sectors of the galaxy were quarantined until at least one race
within them had reached technological maturity.  Given how few shortcuts
were active, some argued that Earth's two sentient species, Homo sapiens
and Tursiops truncatus, were therefore among the first races in the
galaxy to reach that level.

The next year, ships from the Ib homeworld popped through at Tau Ceti
and near Rehbollo--and soon the four races agreed to an experimental
alliance, dubbed the Commonwealth of Planets.

In order to expand the usable shortcut network, seventeen years ago each
homeworld launched thirty boomerangs.

Each of these probes flew at their maximum hyperdrive
velocity--twenty-two times the speed of light--toward dormant shortcuts
that had been detected by their tachyon coronas.  Upon arrival, each
boomerang would dive through and return home, thus activating the
shortcut as a valid exit.

So far, boomerangs had reached twenty-one additional shortcuts within a
radius of 375 light-years from one or another of the three homeworlds.

Originally, these sectors were explored by small ships.  But the
Commonwealth had realized a more comprehensive solution was needed: a
giant mothership from which exploration surveys could be launched, a
ship that could serve not only as a research base during the crucial
initial exploration of a new sector, but also could function as embassy
for the Commonwealth, if need be.  A vast starship capable of not just
astronomical research, but of undertaking first-contact missions as
well.

And so, a year ago, in 2093, Starplex was launched.

Funded by all three homeworlds and constructed at the Rehbollo orbital
shipyards, it was the largest vessel ever built by any of the
Commonwealth races: 290 meters at its widest point, seventy decks thick,
a total enclosed volume of 3.1 million cubic meters, outfitted with a
crew of a thousand' beings and fifty-four small auxiliary ships of
various designs.

Starplex was currently 368 light-years due galactic south of Flatland,
exploring the vicinity of a recently activated shortcut.

The closest star was an F-class subgiant a quarter-light-year away.  It
was surrounded by four asteroid belts, but no planets.  An uneventful
mission so far--nothing remarkable astronomically, and no alien radio
signals detected.  Star-plex's staff was busy winding down its
explorations.  In seven days, another boomerang was due to reach its
designated shortcut target, this one 376 light-years away from Rehbollo.

Starplex's next scheduled assignment was to investigate that sector.

Everything seemed so peaceful, until-- "Lansing, you will hear me out."

Keith Lansing stopped walking down the cold corridor, sighed, and rubbed
his temples.  Jag's untranslated voice sounded like a dog barking, with
occasional hisses and snarls thrown in for good measure.

His translated voice --rendered in-an old-fashioned Brooklyn
accent--wasn't much better: harsh, sharp, nasty.

"What is it, Jag?"

"The apportioning of resources aboard Starplex," barked the being, "is
all wrong--and you are to blame for that.

Before we move to the next shortcut, I demand you rectify this.  You
consistently shortchange the physics division and give preferential
treatment to life sciences."

Jag was a Waldahud, a shaggy piglike creature with six limbs.  After the
last ice age ended on Rehbollo, the polar caps had melted, flooding much
of the land and crisscrossing what remained with rivers.  The
Waldahudin's ancestors adapted to a semiaquatic lifestyle, their bodies
becoming well insulated with fat overlain by brown fur to keep out the
chill of the river waters they lived in.  Keith took a deep breath and
looked at Jag.  He's an alien, remember.  Different ways, different
manners.  He tried to keep his tone even.  "I don't think that's quite
fair."

More dog barks.  "You give special treatment to life sciences because
your spouse heads that division."

Keith forced a small laugh, although his heart was pounding with
repressed anger.  "Rissa sometimes says the opposite--that I don't give
her enough resources, that I'm bending over backward to appease you."

"She manipulates you, Lansing.  She--what is the human metaphor?  She
has you wrapped around her little finger."

Keith thought about showing Jag a different finger.

They're all like this, he thought.  An entire planet of quarrelsome,
bickering, argumentative pigs.  He tried not to sound weary.  "What
exactly is it that you want, Jag?"

The Waldahud raised his upper left hand, and ticked off stubby, hairy
fingers with his upper right.  "Two more probeships assigned exclusively
to physical-sciences missions.

An additional Central Computer bank dedicated to astrophysics.  Twenty
more staff members."

"The staff additions are impossible," said Keith.  "We don't have
apartments to house them.  I'll see what I can do about your other
requests, though."  He paused for a second, and then: "But in the
future, Jag, I think you'll find that I'm easier to convince when you
don't bring my private life into the discussion."

Jag barked harshly.  "I knew it!"  said the translated voice.

"You make your decisions based on personal feelings, not on the merit of
the argument.  You are truly unfit to hold the post of director."

Keith felt his anger about to boil over.  He tried to calm himself, and
closed his eyes, hoping to summon a tranquil image.  He expected to see
his wife's face, but the picture that came to him was of an Asian beauty
two decades younger than Rissa--and that just made Keith madder at
himself.  He opened his eyes.  "Look," he said, a quaver in his voice,
"I don't give a damn whether you approve of the choice of me as Starplex
director or not.  The fact is that I am director, and will be for
another three years.  Even if you could somehow get me replaced before
my term is over, the agreed-to rotation calls for a human to hold this
post at this time.  If you get rid of me--or if I quit because I'm fed
the hell up with you--you're still going to be reporting to a human. And
some of us don't like you"--he stopped himself before he said "you
pigs"--"at all."

"Your posturing does you no credit, Lansing.  The resources I am
demanding are for the good of our mission."

Keith sighed again.  He was getting too old for this.  "I'm not going to
argue anymore, Jag.  You've made your request; I'll give it all the
consideration it is due."

The Waldahud's four square nostrils flared.  "I am amazed," said Jag,
"that Queen Truth ever thought we could work with humans."  He rotated
on his black hooves, and headed down the corridor without another word.

Keith stood there for two minutes, doing calming breathing exercises,
then headed along the chilly corridor toward the elevator station.

Keith Lansing and his wife, Rissa Cervantes, shared a standard human
apartment aboard Starplex: L-shaped living room, a bedroom, a small
office with two desks, one bathroom with human fixtures, and a second
with multispecies fixtures.  There was no kitchen, but Keith, who liked
to cook, had rigged up a small oven so that he could indulge his hobby.

The main door to the apartment slid open, and Keith stormed in.  Rissa
must have arrived a few minutes earlier; she came out of the bedroom
naked, obviously preparing for her midday shower.

"Hi, Chesterton," she said, smiling.  But the smile faded away, and
Keith imagined that she could see the tension in his face, his forehead
creased, his mouth downturned.

"What's wrong?"

Keith flopped himself onto the couch.  From this angle, he was facing
the dartboard Rissa had mounted on one wall.

The three darts were clustered in the tiny sixty-point part of the
triple-scoring band--Rissa was shipboard champion.

"Another run-in with Jag," said Keith.

Rissa nodded.  "It's his way," she said.  "It's their way2' "I know.  I
know.  But, Christ, it's hard to take sometimes."

They had a large rear window on one wall, showing the starfield outside
the ship, dominated by the bright F-class star nearby.  Two other walls
were capable of displaying holograms.  Keith was from Calgary, Alberta;
Rissa had been born in Spain.  One wall showed glacier-fed Lake Louise,
with the glorious Canadian Rockies rising up behind it; the other a long
view of downtown Madrid, with its appealing mixture of sixteenthand
twenty--century architecture.

"I thought you'd show up here around now," said Rissa.

"I was waiting to shower with you."  Keith was pleasantly surprised.

They'd showered together a lot when they'd first gotten married, almost
twenty .years ago, but had gotten out of the habit as the years wore on.

The necessity of showering twice a day to minimize the human body odor
Waldahudin found so offensive had turned the cleansing ritual into an
irritating bore, but maybe their impending anniversary had Rissa feeling
more romantic than usual.

Keith smiled at her and began to undress.  Rissa headed into the main
bathroom and began running the water.  Starplex was such a contrast to
the ships of Keith's youth, like the Lester B. Pearson he'd traveled on
back when first contact with the Waldahudin had been made.  In those
days, he'd had to be content with sonic showers.  There was something to
be said for carrying a miniature ocean around as part of your ship.

He followed her into the bathroom.  She was already in the shower,
soaking down her long, black hair.  Once she'd moved out from under the
shower head, Keith jockeyed into position, enjoying the sensation of her
wet body sliding past his.  He'd lost half his hair over the years, and
what was left he kept short.  Still, he massaged his scalp vigorously,
trying to work out his anger with Jag in doing so.

He scrubbed Rissa's back for her, and she scrubbed his in turn.  They
rinsed, then he turned off the water.  If he hadn't been so angry,
perhaps they'd have made love, but .  . .

Dammit.  He began to towel off.

"I hate this," Keith said.

Rissa nodded.  "I know."

"It's not that I hate Jag--not really.  I hate .  . . hate myself.

Hate feeling like a bigot."  He ran the towel up and down his back.  "I
mean, I know the Waldahudin have different ways.  I know that, and I try
to accept it.  But--Christ, I hate myself for even thinking
this--they're all the same.  Obnoxious, argumentative, pushy.  I've
never met One who wasn't."  He sprayed deodorant under each arm.  "The
whole idea of thinking I know all about somebody just because I know
what race they belong to is abhorrent--it's everything I was brought up
to understand.  And now I find myself doing it day in and day out."  He
sighed.

"Waldahud.

Pig.  The terms are interchangeable in my mind."

Rissa had finished drying herself.  She pulled on a beige long-sleeve
shirt and fresh panties.  "They think the same way about us, you know.

All humans are weak, indecisive.

They don't have any korbaydin."

Keith managed a small laugh at the use of the Waldahudar word.  "I do
too," he said pointing down.  "Of course, I only have two instead of
four, but they do the job."  He got a fresh pair of boxer shorts and a
pair of brown denim pants out of the closet, and put them on.  The pants
constricted to fit around his waist.  "Still," he said, "the fact that
they also generalize doesn't make it any better."  He sighed.  "It
wasn't like this with the dolphins."

"Dolphins are different," said Rissa, pulling on a pair of red pants.

"In fact, maybe that's the key.  They're so different from us that we
can bask in those differences.  The biggest problem with the Waldahudin
is that we have too much in common with them."

She moved over to her dresser.  She didn't put on any makeup; the
natural look was the current style for both men and women.  But she did
insert two diamond earrings, each the size of a small grape.  Cheap
diamond imports from Rehbollo had destroyed any remaining value natural
gemstones had, but their innate beauty was unsurpassed.

Keith had finished dressing, too.  He'd put on a synthetic shirt with a
dark brown herringbone pattern, and a beige cardigan sweater.

Thankfully, as humanity moved out into the universe, one of the first
bits of needless mass to be ejected had been the jacket and tie for men;
even formal wear did not demand them anymore.  With the advent of the
four-day, and then the three-day, workweek on Earth, the distinction
between office clothes and leisure clothes had disappeared.

He looked over at Rissa.  She was beautiful--at forty-four, she was
still beautiful.  Maybe they should make love.

So what if they just got dressed?  Besides, these crazy thoughts
aboutBleep.  "Karendaughter to Lansing."

Speak of the devil.  Keith lifted his head, spoke into the air.

"Open.

Lianne Karendaugliter's rich voice came out of the wall speaker.

"Keith--fantastic news!  A watson just came through from CHAT with word
that a new shortcut has come on-line!"

Keith raised his eyebrows.  "Did the boomerang reach Rehbollo 376A ahead
of schedule?"  That sometimes happened; judging interstellar distances
was a tricky game.

"No.  This is a different shortcut, and it came on-line because
something--or, if we're lucky, someone-- moved through it locally."

"Has anything unexpected come through any of the homeworld shortcuts?"

"Not yet," said Lianne, her voice still bubbling with excitement.  "We
only discovered this one was now on-line because a cargo module
accidentally got misdirected to it."

Keith was on his feet at once.  "Recall all probeships," he said.

"Summon Jag to the bridge, and alert all stations for a possible
first-contact situation."  He hurried out the apartment door, Rissa
right behind him.

BETA DRACONIS

Keith Lansing looked around the docking bay aboard the strange alien
craft.  Like the ship's exterior, this part, too, was featureless.  No
seams, no equipment, nothing marring the six glowing cube faces.

When the shortcuts were discovered, the press had delighted in bandying
around a centurY-old saying, attributed to the Sri Lankan writer Arthur
C. Clarke: "Any sufficiently advanced technology is indistinguishable
from magic."

The shortcuts were magic.

And so was this strange, beautiful starship, this starship that moved in
apparent defiance of Newton's laws .  . .

Keith took a deep breath.  He knew what was about to happen, knew it in
his bones.  He was about to meet the makers of the shortcuts.

The pod's course across the bay curved gently downward and soon it came
to rest on the flat lower face of the bay.

Keith felt weight returning.  It continued to grow slowly, and he
settled to the floor.  The gravity kept increasing, more and more, until
it had reached Starplex's shipboard standard.

But still it grew, and Keith fought a wave of panic, fearing he would be
crushed to jelly.

Finally, though, it stopped--and Keith realized that it was at just
about the level he kept it at in his cabin aboard ship, nine percent
higher than the Commonwealth standard but equal to Earth's sea-level
surface gravity.

And then, suddenly-- Everything around him was .  . . was familiar.

Was Earth.

The edge of a mixed forest, maple trees and spruces rising to a sky the
shade of blue no other planet he'd ever seen had.  Sunlight precisely
the color of Sol's--matching the antihomesickness lamps he and Rissa had
in their apartment aboard Starplex.  To his right, a lake covered with
lily pads, bulrushes rising from its edge.  Overhead, a V-shaped flock
of--no mistake--of Canada geese, and--yup, just to dispel any final
doubt, a daytime gibbous moon, showing the Sea of Tranquility and the
O-shaped Sea of Crises to its right.

An illusion, of course.  Virtual reality.  Make him feel at home.

Perhaps they could read his mind, or perhaps they'd already contacted
other travelers from Earth.

The travel pod had no elaborate sensors.  There was air in the bay,
though.  He could hear--God, he could hear crickets, and bullfrogs, and,
yes, the haunting call of a loon, all transmitted through the hull of
the ship from the air outside.  No way to test a sample, but they
couldn't have gotten all the other details right and screwed up on
something as simple as the gas mixture for human-breathable air.

And yet, he hesitated.  The trip to Tau Ceti was supposed to be a simple
run; Keith hadn't even bothered to see if there was a spacesuit in the
pod's emergency locker before departure.

But it was clearly an invitation--an invitation to first contact.  And
first contact was what Starplex was all about.

Keith touched a series of controls, overriding the safety interlocks
that kept the pod's rear door from opening when it wasn't connected to
an access ring.  The glassteel panel slid up into the roof.

Keith took a tentative breath-- And sneezed.

Jesus Christ, he thought.  Ragweed pollen.  These guys were good.

He sniffed again, and could smell all the things he'd have smelled if he
really were back on Earth.  Wildflowers and grass and damp wood and a
thousand other things, subtly mixed.  He stepped out.

They'd thought of everything--a perfect re-creation.

Why, he even left footprints in the soft earth, something most
virtual-reality simulations tripped up on.  Indeed, he could feel the
texture of the ground through the soles of his shoes, feel it give with
each step, feel the springiness of grass compressing beneath his feet,
the sharp jab of a stone.  It was perfect .  . .

And then it hit him.  Maybe he was back on Earth.  The shortcut makers
knew how to cut across space in the twinkling of an eye.  Maybe this was
the real thing, maybe he was home-- But there had been no second
shortcut inside the docking bay, no flash of purple Soderstrom
radiation.  And besides, if this was Earth, where had they found such
unspoiled wilderness?  He looked again at the sky, searching for an
airplane or shuttle contrail.

Still--his sneezing meant they'd actually manufactured allergen
molecules, or were manipulating his mind on a very sophisticated level.

Suddenly Keith felt his throat constricting.  A zoo/ A goddamned zoo,
and he was a specimen in it.  He was trapped, a prisoner.  He turned
around, about to rush back to his pod, and saw the glass man.

"Hello, Keith," said the man.  His whole body was transparent, made of
perfect crystal that flowed as he moved.  There was only the faintest
hint of color to the transparent form, a touch of cool aquamarine.

Keith said nothing for several seconds.  The pounding of his heart was
drowning out the wilderness sounds.  "You know who I am?"  he said at
last.

"Sort of," said the glass man.  His voice was masculine, deep.  His
body, although humanoid, was stylized, like a mannequin in a trendy
store.  His head was a featureless'egg shape, with the point forming the
chin.  Although the arms and legs seemed well proportioned, they were
smooth, without any apparent musculature.  The belly and chest were
flat, and the transparent sex organ between the legs was simplified,
rocket-shaped.

Keith stared at the glass man, wondering what to do next.

Finally, desperate to know his status, he said: "I want to leave."

"You may," said the glass man, spreading his transparent arms.

"Anytime you wish.  Your pod stands waiting for you."  There was no sign
of a speaking orifice on the simple ovoid head, but Keith's ears told
him the sound was indeed emanating from it.

"This--this isn't a zoo?"  asked Keith.

There was a sound like wind chimes--glassy laughter?

"No."

"And I'm not a prisoner?"

The wind chimes again.  "No.  You are--is 'guest' the right word?  You
are my guest."

"How can you speak English ?"

"I don't, actually, of course.  My reckoner is translating the words for
you."

"Did you make the shortcuts?"

"The what?"

"The shortcuts.  The interstellar gateways, the stargates--whatever you
want to call them."

"'Shortcuts,'" said the glass man, nodding.  "A good name for them.

Yes, we created them."

Keith 's pulse was racing.  "What do you want from me ?"

The wind chimes once more.  "You seem defensive, Keith.

Isn't there some standard speech you're supposed to make in a
first-contact situation?  Or is it too early for that?".

Too early?  "Well, yes."  Keith swallowed.  "I, G. K.
Lansing, Director of Starplex, bring you friendly greetings from the
Commonwealth of Planets, a peaceful association of four sentient races
from three different homeworlds."

"Ah, now that's better.  Thank you."

Keith was struggling to take it all in: the transparent humanoid, the
forest re-creation, the beautiful starship, the diverting of his pod.

"I'd still like to know what you want from me," he said at last.

The glass man tipped his featureless head at Keith.  "Well, at the risk
of sounding melodramatic, the fate of the universe is in question."

Keith blinked.

"But, more than that," said the glass man, "I need to ask you some
questions.  For you see, Keith Lansing, you hold not only the key to the
future, but also to the past."

Chapter II

A new sector of space--and one that had opened unexpectedly.

Keith and Rissa hurried to the bridge, entering through the port-side
door .  . which meant that Keith had to pass right by Lianne
Karendaughter.  Brilliant (a master's in electrical engineering from
MIT), beautiful (luscious Asian features, mounds of platinum hair pinned
up by gold clips), and young, Lianne had joined Starplex just six weeks
ago, after a distinguished term as chief engineer on a large commercial
hyperliner.  She smiled at Keith as he passed--a radiant smile, a
supernova smile.  Keith felt his stomach flutter.

Starplex's bridge appeared to have no walls, floor, or ceiling.

Instead, it was enveloped by a spherical hologram of the ship's
surroundings, its workstations seemingly floating amongst the stars.

The actual room was rectangular, with a doorway built into each wall,
but the doors were invisible, lost within the spacescape.  When they
split down the middle and slid aside, it was as though space were
opening up, revealing the corridors beyond.  Apparently suspended in
midair--but really attached to the invisible walls just above the
doors--were trios of glowing clocks in each homeworld's time keeping
system.

Keith and Rissa hurried to their workstations, looking as though they
were running in space.

The bridge workstations were laid out in two rows of three, with the
director's position in the middle of the back row.  The front row was
constantly occupied.  The rear stations were only used when necessary;
Jag, Keith, and Rissa all had separate offices where they did most of
their work.  By default, one of Keith's monitors showed a chart.of who
was currently authorized to use each bridge station.  It was the
standard alpha-shift team in the front row:

Internal Operations Lianne Karendaughter

Helm Thoraid Magnor

External Operations Rhombus


Physical Sciences Jag Kandaro em-Pelsh

Director Keith Lansing

Life Sciences Clarissa Cervantes

The InOps manager was responsible for
all onboard activities, including engineering.  On the opposite side of
the room was her opposite number, the ExOps manager, who supervised the
docking bays and missions conducted by the fifty-four assorted ships
stored there.  To Keith's left was the station for Jag, head of physical
sciences.  To his right, again an opposite number: Rissa, head of life
sciences.

Since most physics research was conducted aboard ship, it made sense
that InOps was in front of the physics station.

Lianne could swivel her chair around, or rotate the workstation on its
turntable base, for face-to-face consultations with Jag.  Likewise, most
life-sciences work was done away from the mothership; Rhombus at ExOps
could easily consult with Rissa (although being an Ib, Rhombus had
360-degree vision; he didn't have to turn around to see her).

To make communication.  even easier, ten-centimeter-high real-time
holograms of Lianne and Thor's heads, plus a full body shot of Rhombus,
normally floated above the rim of Jag, Keith, and Rissa's consoles;
those in the front row had holos of the back-row heads floating above
their stations.

On each side of the room was a large pool covered by an antisplash
forcefield; any of the workstations could have its functions transferred
to a dolphin in either pool.  Behind the workstations was a row of nine
polychairs for observers.

Keith watched as Jag entered through the starboard door.

The Waldahud moved across the starfield, squat bow legs carrying him in
short steps, four arms stiff at his sides.  Jag wore a couple of
functional pieces of clothing, including a belt with storage pouches
depending from it, and a band with a pocket on it around his upper left
arm.  The damned thing was practically naked except for his thick fur
while Keith was freezing to death.  The ship's common areas were kept at
fifteen degrees Celsius, equivalent to a hot summer's noon on Rehbollo.

Keith half expected to see his breath whenever he left his apartment.

As Jag sat down, the Waldahud's monitor screens configured themselves to
be twice as tall as they were wide.  Jag could watch two of them
simultaneously, one with his vertically stacked left pair of eyes, the
other with his vertically stacked right pair.  Like humans, Waldahudin
had two-sided brains, but each of their hemispheres could process a
separate stereoscopic image.

There was no flicker of expression on Jag's face--not that Keith was
good at decoding such things, anyway.  Their altercation in the corridor
an hour ago merited no comment, apparently.  Of course not, thought
Keith.  Just business as usual for one of them.

He shook his head, and turned away.  Thoraid Magnor, at the helm
station, was a giant human of about fifty, with a fiery red beard.  At
ExOps, the polychair had been retracted beneath the floor, and the
console lowered on its slim legs to accommodate its current user.

Rhombus, like all Ibs, resembled a stone wheelchair with a watermelon in
the seat.

One of Keith's monitors was already showing the report from CHAT--the
Commonwealth Hyperspace Astrophysics Telescope--about the newly
activated shortcut.  The exit was in the Perseus Arm, some ninety
thousand light-years from their current location.  And that was all that
was known about it, except that something had recently gone through this
shortcut, activating it.  What that something was, and where it had gone
through the network, was anyone's guess.

"All right, everyone," said Keith.  "We'll start with a standard
alpha-class probe.  Thor, move us to within twenty klicks of the
shortcut."

"Give me two seconds, boss," said Thor.  Keith could simultaneously see
Thor's face in the miniature hologram, and the back of his real head at
the station in front of his.  His face was large and rough, his beard
and hair long and wild.

Keith had seen a Viking helmet on a shelf in Thor's shipboard apartment
once; it would have suited him.  We ve got a probeship in the process of
docking."

A moment later, lights flashed on Rhombus's sensor web.

"I announce with pleasure that the Marc Garneau is secured in docking
bay eight," said a voice with a British accent in Keith's ear.  By
convention, Waldahud voices were translated into English with
old-fashioned New York accents, while the Ibs were assigned British
ones--it made it easier to sort out who was speaking, since the
translated voices all came from the same source, the listener's cochlear
implant.

"Okay, boss," said Thor.  "Here we go."  In front of him, Keith could
see Thor's large hands manipulating controls.

About five minutes later, the stars stopped moving again.  "As
requested, boss," said Thor.  "Twenty thousand meters from the shortcut, on
the button."

"Thank you," said Keith.  "Rhombus, please launch the probe."

Rhombus's ropelike tentacles snapped across his console as if he were
whipping it into submission.  His sensor web flashed.  "A pleasure to do
so."

A schematic of the probe appeared on one of Keith's monitors: a silver
cylinder, four meters long by one in diameter, its surface studded with
scanners, sensors, camera lenses, and CCD plates.  The probe had only
thruster power and four clusters of conical attitude-control jets; a
hyper- drive engine was far too expensive to risk, given that the probe
might never come back.

The probe accelerated through a mass-driver tube in one of Starplex's
upper-habitat modules.  As soon as the probe was out in space, the
bridge staff could see the glow of its thrusters in the holographic
sphere surrounding them.  The probe rotated along its axis so that each
of its instruments would be exposed to the entire panorama of the sky.

There was no visible target for the probe--at least, not yet.  But its
course had been computed so that it would enter the shortcut at the
exact angle specified by CHAT.  When it did so, the probe seemed to
disappear, a tiny ring of violet fire swallowing it up.

"In friendship I observe that passage through the shortcut was normal,"
reported Rhombus in his rich Oxford tones.

And now the waiting began.  Each person showed tension in a different
way.  Lianne at InOps drummed her painted fingernails on the edge of her
console.  The lights on Rhombus's web flashed randomly--not a coherent
pictogram, but just a sign of mental agitation.  Jag picked at his fur
and slid his translucent dental plates across each other, making a faint
chalk-on-slate sound.  Keith got up and paced.  Rissa busied herself
organizing files on her computer.

Only the unflappable Thoraid Magnor seemed calm, swinging his giant feet
onto his console, and leaning back in his chair, hands interlaced behind
his orange mane.

But despite Thor's appearance, there was reason for concern.  Ten years
ago, a boomerang launched from Tau Ceti had reached its target, a
dormant shortcut near the M3-class star Tejat Posterior in the
constellation Gemini.

That boomerang never returned to Tau Ceti.  Instead, at about the time
it was supposed to come home, a smooth ball of metal shot out of the
Rehbollo shortcut.  Analysis determined that the ball was the remains of
the probe after some process had briefly broken all molecular bonds in
its construction.

The word "process" had been deliberately chosen for the public reports,
but many believed that no natural activity could have done that, not
even if the Tejat Posterior shortcut exit had been inside a star's core.

The hypothetical beings responsible were dubbed "Slammers," because
they'd apparently slammed the interstellar doorway in the Commonwealth's
collective face.

Additional hyperspace probes with heavy shielding had been sent toward
Tejat Posterior (from launch points well away from any-of the
Commonwealth homeworlds), but it would still be another two years before
they arrived there.

Until they did, the mystery of the Slammers remained unresolved--but
there was always a fear that they might be lurking behind other
shortcuts.

"With relief, I report a tachyon pulse," announced Rhombus.

Keith let out his breath; he hadn't been aware that he'd been holding it
until then.  The pulse meant something was coming through the shortcut;
the probe was returning.  They watched as the shortcut grew from an
infinitesimal point to a meter in diameter, with a violet periphery. The
cylindrical object popped through.  Keith nodded slightly: the probe
appeared undamaged.  It maneuvered back toward Starplex under its own
power, meaning its internal electronics were still intact, and slid down
the launching tube into its berth.

Umbilicals were attached to it, and its store of data was uploaded into
PHANTOM, Starplex's central computer.

"Let's see it," Keith said, and Rhombus complied, replacing the
spherical hologram of space outside Starplex with what the probe had
seen on the other side of the shortcut.  At first, it just seemed to be
more space, different constellations enveloping them.  There were
murmurs of disappointment.

One always hoped that a spacecraft would be visible--a ship from
whatever race had brought the shortcut on-line.

Jag got out of his chair, and walked around to stand in front of the two
rows of workstations.  He rotated on his hooves, looking at various
parts of the hologram, then began interpreting what was visible for the
rest of them.  "Well," said a translated Brooklyn accent overtop of his
dog barks, "it looks like normal interstellar space.  Just what you'd
expect for the Perseus Arm--lots of blue stars, not too densely packed."

He stopped and pointed.  "See that band of light?

We're on the inner edge of the Perseus Arm, looking back toward the
Orion Arm.  Neither Galath nor Hotspot would be visible from here, but
we might be able to find Sol in a telescope."

He began a circumnavigation of the bridge, his black' hooves ticking
against the invisible floor.  "The only thing that looks bright enough
to be a nearby main-sequence star is that one there."  He indicated a
blue-white point that was indeed brighter than all the others.  "Still,
it shows no sign of a visible disk, so at a minimum we are several
billion kilometers from it.  Of course, we can use a couple of probes to
do some long-base-line parallax tests to see how close it is as soon as
we go through the shortcut; I don't normally favor A-class stars for
having habitable planets, but it seems as good a place as any to start
looking for whoever activated this exit."

"So you think it's safe for us to go on through?"  Keith asked.

The Waldahud turned to face him, and his left pair of eyes blinked.

"There doesn't appear to be any immediate danger," he said.  "I'll want
to review the rest of the probe's data, but it looks just like, well,
space."

"Okay.  In that case, let's try--"

"Just a second," said Jag, apparently catching sight of a part of the
hologram over Keith's shoulder.  He walked toward the director, then
continued on, past the seating gallery behind his station.  "Just a
second," he said again.

"Rhombus, how much real-time hologram is left?"

"I abase myself to admit we exhausted the real-time playback two minutes
ago," said the Ib at the ExOps console.  "I've been looping the playback
since then."

Jag walked over to the bridge wall--which was something like taking a
few steps toward a distant mountain in hopes that doing so would improve
one's view of it.  He peered into the darkness.  "That area there," he
said, circling his upper left ann to indicate a large portion of the
starfield.

"There is something unusual .  . . Rhombus, speed up the playback.  Ten
times normal rate, and loop it continuously."

"Done without rancor," said Rhombus, ropes snapping.

"That can't be," said Thor, who had turned around to look as well.  He
half rose from his chair at the helm console.

"But it is," said Jag.

"What is it?"  asked Keith.

"You see it," said Jag.  "Look."

"All I see is a bunch of stars twinkling."

Jag lifted his upper shoulders, the Waldahud equivalent of a nod of
assent.  "Exactly.  Just like a clear winter's night back on your
wondrous Earth, no doubt.  Except," he said, "that stars do not twinkle
when seen from space."

**GAMMA DRACONIS**

You hold, the glass man had said, not only the key to the future, but
also to the past.  The glass man's words echoed in Keith's mind.  He
looked around at trees, the lake, the blue sky.  All right, all
right--Glass had said it was not a cage, not a zoo, that he could leave
at any time.  Still, his head was reeling.  Maybe it was because all
this was too much to take in at once, despite Glass attempt to provide
familiar surroundings.  Or maybe the sensation was an aftereffect of
Glass's mind-probe--Keith still suspected something like that was at
work here.  Either way, he found himself feeling dizzy, and decided to
lower his body down to the grass.  At first he knelt, but then he moved
into a more comfortable position, with his legs sticking out to one
side.  He was astonished to see he'd gotten a grass stain on the knee of
his pants.

The glass man flowed into a lotus position about two meters away from
Keith.  "You introduced yourself as G. K. Lansing."

Keith nodded.

"What does the G stand for?"

"Gilbert."

"Gilbert," said Glass, nodding his head as if this was significant.

Keith was perplexed.  "Actually, I go by my middle name, Keith."  A
self-deprecating chuckle.  "You would, too, if your first name was
Gilbert."

"How old are you?"  asked Glass.

"Forty-six."

"Forty-six?  Just forty-six?"  The being's tone was strange--wisful or
perplexed.

"Um, yes.  Forty-six Earth years, that is."

"So young," Glass said.

Keith lifted his eyebrows, thought about his bald spot.

"Tell me about your mate," asked Glass.

Keith's eyes narrowed.  "Why would you possibly be interested in that?"

Wind-chime laughter.  "I am interested in everything."

"But questions about my mate--surely there are more important things to
explore?"

"Are there more important things to you?"

Keith thought for a second.  "Well--no.  No, I suppose there aren't."

"Then tell me about--about her, I presume."

"Yes, her."

"Tell me."

Keith shrugged.  "Well, her name is Rissa.  That's short for Clarissa.

Clarissa Maria Cervantes."  Keith smiled.  "Her last name always makes
me think of Don Quixote."

"Who?"

"Don Quixote.  The Man of La Mancha.  Hero of a novel by a writer named
Cervantes."  Keith paused.  ';You'd like Cervantes--he once wrote a book
about a glass man.

Anyway, Quixote was a knight-errant, caught up in the romance of noble
deeds and the pursuit of unattainable goals.  But .  . ."

"But what?"

"Well, the funny thing is that #was Rissa who used to call me quixotic."

Glass tipped his head in puzzlement, and Keith realized that he couldn't
discern the connection between the unknown and apparently unrelated
words kwik-sah-tik and kee-hoe-te.  "'Quixotic' means similar to Don
Quixote," sam Keith.  "Visionary, romantic, impractical--an idealist
bent on righting wrongs."  He laughed.  "Of course, I wasn't content to
love Rissa pure and chas-chime laughter.  but I suppose I do have a
tendency to take on battles other people let pass, or aren't even aware
of, and, well .  . ."

The egg-shaped transparent head tilted slightly.  "Yes ?"

"Well," said Keith, spreading his arms, encompassing not just the forest
simulation but everything beyond, "we did reach the unreachable stars,
didn't we?"  He grew silent, feeling a little embarrassed.

"Anyway, you were asking about Rissa.  We have been married--permanently
pair-bonded--for almost twenty years now.  She's a biologist--an
exobiologist, to be precise; her specialty is life that is not
indigenous to Earth."

"And you love her?"

"Very much indeed."

"You have children."  Keith assumed it was a question, but Glass's voice
did not rise at the end of the sentence.

"One.  His name is Saul."

!'Sol?  After your home star?"

"No, Saul.  S-A-U-L.  After the man who had been my best friend before
he died, Saul Ben-Abraham."

"So your son's name was--what?  Not Saul Lansing-Cervantes ?"

Keith was surprised that Glass grasped human naming conventions.  "Yes,
that's right."

"Saul Lansing-Cervantes," repeated Glass, his head tilted as if lost in
thought.  He looked up.  "Sorry.  It's, ah, quite a musical name."

"Which you'd say is funny, if you knew him," said Keith.

"I love my son, but I've never met anyone with less musical talent.

He's nineteen now, and is away at university.  He's studying physics,'
that's something he does have an aptitude for, and I suspect someday
he'll make quite a name for himself in that field."

"Saul Lansing-Cervantes .  . . your son," said Glass.

"Fascinating.  Anyway, we keep getting off the topic of Rissa.  "

Keith looked at him for a moment, puzzled.  But then he shrugged "She's
a wonderful woman.  Intelligent.  Warm, funny.  Beautiful."

"And you say you are pair-bonded with her?"

"That's right."

"And that means .  . . monogamy, correct?  You couple with no one else?"

"Yes."

"Without exception?"

"Without exception, that's right.  "A pause.  "So far."

"So far?  You are contemplating a change in this relationship?"

Keith looked away.  Christ, this is crazy.  What could this alien
possibly know about human marriage ?  "Move along," said Keith.

"Pardon?"  asked Glass.

"Move along, move along.  Another topic."

"Do you feel guilty, Keith ?"

"What are you--my bloody conscience?"

"I am just someone who is interested, that's all."

"Become interested in something else."

"I'm sorry," said Glass.  "Where did you and Rissa first meet?"

"La Belle Aurore.  The Germans wore gray; she wore blue."

"Pardon ?"

"Sorry.  Another knight-errant hero of mine said that.  We met at a
party on New Beijing--that's the Earth colony on Tau Ceti IV.  She was
working in the same lab there as someone I had gone to school with."

"Was it--what is the saying?  Was it love at first sight?"

"No.  Yes.  I don't know."

"And you have been married for twenty years?  asked Glass.

"Just about.  Our anniversary is next week."

"Twenty years," said Glass.  "A blink of an eye."

Keith frowned.  "Actually, it's considered quite an achievement to make
it work that long."

"Apologies for my comment," said Glass.  "Congratulations."

A pause.  "What do you like most about Rissa?"

Keith shrugged.  "I don't know.  Several things.  I like that she is
content with who she is.  Me, I've got to put on airs--to sometimes
pretend I've accomplished more, or am more sophisticated, than I really
am.  In fact, it's common among humans .who have attained a significant
position to suffer from what's called "the impostor syndrome'--the fear
that others are going to discover that they don't deserve what they've
got.  I admit to having a touch of that, but Rissa is immune to it.

She never pretends to be anything she's not."

Glass nodded.

"And I like her equanimity, her evenness of temper.  If something goes
wrong, I tend to swear and get upset by it.

She just smiles and does whatever needs to be done to set things right.

Or if they can't be set right, she accepts it."

Keith paused.  "In many ways, she's a better person than I."

Glass seemed to consider this for a moment.  "She sounds like someone
you should hold on to, Keith."

Keith looked at the transparent man, perplexed.

Chapter III

A child's blocks.  That's the image that had come to' Keith
ansmg s mind two years ago, while watching Starplex's components being
assembled at the Rehbollo orbital shipyards.

The giant ship was made up of just nine pieces, eight of which looked
identical.

The largest piece was the central disk/shaft combination.

The disk was 290 meters in diameter and 30 meters thick.

The square shaft extended up and down from the center of the disk 90
meters in each direction, making Starplex a total of 210 meters tall.

A parabolic radio/hyperspace-telescope dish was set into each of the
shaft's end caps.

The central disk actually consisted of three wide rings surrounding the
shaft.  First, stretching out to a radius of 95 meters was the vast
space that would be filled with 686,000 cubic meters of salt water,
forming the ocean deck.  Second, twenty meters wide and ten decks thick,
was the engineering torus.  The final ring consisted of Starplex's eight
mammoth cargo holds and twenty docking bays, their space doors arrayed
along the disk's curving edge.

The other building blocks were the eight habitat modules.

Each was a right-triangular prism, ninety meters tall, ninety meters
wide at its base, and thirty meters thick.  One module was attached to
each of the four sides of the shaft that stuck out above the disk.

These were mirrored by four more mated to the portion that protruded
below.  In profile the assembled ship resembled a diamond with a bar
through it; seen from above, it was a circle with the interlocking
habitats forming a cross in its center.

Each habitat module was divided into thirty decks.  Any of the modules
could be replaced to accommodate a new race or special equipment, or one
could be left behind as a separate base for long-term explorations in a
new sector.

In the year since the ship had been launched, Starplex's missions had
been uneventful.  But now, at last, a real first-contact situation was
at hand.  Now, at last, all that the great ship had to offer would be
put to the test.

A second, more sophisticated probe was sent through to the newly opened
sector.  It, too, detected the twinkling stars, and its hyperspace
telescopes indicated a solar system's worth of mass was present in the
vicinity; to get more resolution of exactly how the mass was deployed
would require much larger 'scopes, such as those that were set into
either end of Starplex's central shaft.

Keith next ordered a probeship with a human and an Ib from Jag's staff
to fly through to the other side and do a more complete reconnaissance.

They didn't actually travel into the source of the twinkling stars.

There was no way to communicate in real time through a shortcut, so if
they got in trouble it might be too late to help before Starplex
realized it.  But they did do full-spectrum EM scans, a complete-sky
search for artificial radio signals, and so on.

They returned to Starplex, reporting that there was no apparent danger
on the other side, although the cause of the twinkling starscape
remained as elusive as ever.

Keith waited until all data from the two probes and the crewed
reconnaissance had been reviewed by each department.

Finally, satisfied that it would represent a low risk, he ordered Thor
to take Starplex itself through the shortcut into the newly opened
sector of space.

People occasionally used the terms "wormhole" or "tunnel" as synonyms
for shortcut, but that wasn't correct.  There was no intervening space
between the shortcut entrance and the exit.  They were like doors
between rooms in a house with paper-thin walls: as you walked through,
you were partly in one room and partly in another.  As simple as
that--except that the rooms were separated by many light-years.

The Commonwealth had slowly worked out how to navigate the shortcut
network.  In normal space, a dormant shortcut is a point.  But in
hyperspace, that point is surrounded by a rotating sphere of tachyons.

The tachyons move along millions of polar orbital lines, all of which
are equally spaced, except that one is missing on one side, its tachyon
looping back in a hemispherical path.  That narrow tachyon-free gap is
known as "the zero meridian," and it means you can treat the sphere of
tachyons just like a planetary globe, with a coordinate system of
longitude and latitude.

To travel through a shortcut, you set a straight-line path toward the
point at the center of the sphere.  As you approach that point, you pass
through the sphere at a specific latitude and longitude.  Those
coordinates determine which other shortcut you will exit from: where in
the galaxy you come out depends on the direction from which you
approached the local shortcut.

Of course, to get the ball rolling, there had to be one shortcut on-line
at the outset that was not associated with any race--otherwise there'd
be no location for the first emerging civilization to travel to with
their shortcut.  The initial shortcut--Shortcut Prime--was clearly a
freehie, given by the shortcut makers.  It was located in the heart of
the Milky Way galaxy, within sight of the central black hole.

Earth's initial explorations of that sector had found no native life
there, of course; the galactic core was far too radioactive for that.

At the beginning of the Commonwealth, there were only four active
shortcuts--Tau Ceti, Rehbollo, Flatland, and Shortcut Prime.  As more
shortcuts were activated, the acceptable approach angles for each
possible exit became smaller.  After a dozen shortcuts were on-line, it
became clear that to return to the Tau Ceti shortcut, one had to pierce
the tachyon sphere surrounding another shortcut at about 115 degrees
east longitude and 40 degrees north latitude.  On Earth, that's close to
Beijing, which gave rise to the "New Beijing" nickname for the colony on
Silvanus, Tau Ceti's fourth planet.

When a ship touches the shortcut, the shortcut point expands--but only
in two dimensions.  It forms a hole in space perpendicular to the
direction of the ship's travel.  The hole's shape is the same as the
cross-sectional profile of whatever part of the ship is passing through
it.  The opening is outlined in a violet ring of Soderstrom radiation,
caused by tachyens spilling out around the edges and spontaneously
translating into slower-than-light particles.

An observer looking at the shortcut from the front would see the ship
disappearing into the violet-limned entrance.

Looking from the back, he or she would only see a black void blocking
the background stars; the void would have the same silhouette as the
disappearing object.

Once the ship is all the way through, the shortcut loses its height and
width, collapsing back down to nothingness--awaiting the next galactic
traveler .

Thor sounded the pretransfer alarm, five successively louder electronic
drumbeats.  Keith touched keys, and his number-two monitor switched to a
split-screen mode.  One side displayed normal space, in which the
shortcut was invisible; the other, a computer simulation based on
hyperspace scans, showing the shortcut as a bright white point on a
green background surrounded by a glowing orange sphere of field lines.

"All right," said Keith.  "Let's do it."

Thor operated controls.  "As you say, boss."

Starplex closed the twenty kilometers between itself and the shortcut,
and then it touched the point.  The shortcut expanded to accommodate the
ship's diamond-shaped profile, fiery purple lips matching the giant
mothership's shape.

As Starplex passed through, the holographic bubble surrounding the
bridge showed the two mismatched starfields, and the stormy
discontinuity between hem that moved from bow to stern as they completed
their passage.  As soon as the ship was all the way through, the
shortcut shrank back down to nothingness.

And there they were, in the Perseus Arm--two thirds of the way across
the galaxy, and tens of thousands of light-years from any of the
homeworlds.

"Shortcut passage was normal," said Thor.  The tiny holegram of his face
floating above the rim of Keith's workstation was lined up with the back
of Thor's actual head, and the holographic mass of red hair blended into
the real mane beyond, making his ax-blade features seem lost in a vast
orange sea.

"Good work," said Keith.  "Let's drop a marker buoy."

Thor nodded and pushed some keys.  Although the shortcut stood out in
hyperspace, if Starplex's hyper-radio equipment broke down, they'd have
trouble finding it again.

The buoy, broadcasting on normal EM frequencies and containing its own
hyperscope, would be their beacon home in that case.

Jag got up and pointed out the twinkling stars again; they were quite
easy to see.  Thor rotated the holographic bubble so that they appeared
front and center, instead of off behind the observation gallery.

Lianne Karendaughter was leaning forward at her workstation, a delicate
hand supporting her chin.  "So what's causing the twinkling?"  she said.

Behind her, Jag lifted all four shoulders in a Waldahud shrug.  "It
can't be atmospheric disturbances, of course," he said.  "Spectrographs
confirm that we're in a space-normal vacuum.  But something is in
between our ship and the background stars--something that is at least
partially opaque and shifting."

"Perhaps a nonluminous nebula," said Thor.

"Or, if I may be allowed a suggestion, perhaps just a tract of dust,"
said Rhombus.

"I'd like to know how far away it is before I hazard 'a guess," said
Jag.

Keith nodded.  "Thor, shoot a comm laser at--at whatever it is/'

Thor's broad shoulders moved as he worked controls on either side of his
workstation.  "Firing."

Three digital counters appeared floating in the holographic display.

Each one incremented at a different rate, in the smallest standard units
of each of the three homeworld's time keeping systems.  Keith watched
the one counting seconds climb higher and higher.

"Reflected light received at seventy-two seconds," said Thor.

"Whatever is out there is pretty damn close--about eleven million klicks
away."

Jag was consulting his monitors.  "Hyperspace telescope readings show
that the obstructing material consists of a large amount of mass--a
sixteen-multiple or more times the combined mass of all the planets in a
typical solar system."

"So it's not spaceships," said Rissa, disappointed.

Jag lifted his lower shoulders.  "Probably not.  There's a small chance
that we're seeing a large number of vessels--a vast fleet of craft,
whose individual movements are eclipsing background stars, and whose
artificial gravity generators are making big dents in spacetime.  But I
doubt that."

"Let's close the distance by half, Thor," said Keith.

"Bring us in to about six million klicks from the periphery of the
phenomenon.  See if we can make out more detail."

The little face and the big head behind it nodded in unison.  "As you
say, boss."

As he brought the ship closer, Thor also rotated Starplex so that deck
one was facing forward into its direction of movement.  The ship's
thrusters could move the vessel in any direction, regardless of its
orientation, but one of the twin radio telescopes was mounted in the
center of that square deck, and four optical telescopes were mounted at
the corners.

As they got closer, it became apparent that whatever was obscuring the
background stars was reasonably solid and large.  Stars were being
eclipsed now with only a short period of fading out as they disappeared.

But there wasn't enough light to see clearly.  The nearby A-class star
was just too far away.  So far, all that they could make out was a
series of maddeningly vague shadows.

"Any radio signals?"  asked Keith.  As had become his habit, he'd shut
off the hologram of Lianne's head that by default hovered above the rim
of his console.  In the past, he'd found himself staring at it, and that
was awkward with Rissa sitting right next to him.

"Nothing major," she said.  "Just wisps of milliwatt noise now and again
near the twenty-one-centimeter line, but it's all but lost against the
cosmic microwave background."

Keith looked to Jag, seated on his left.  "Ideas?"

The Waldahud was growing frustrated as they got closer--his fur was
standing up in tufts.  "Well, an asteroid belt seems unlikely,
especially this far from the nearest star.  I suppose it could be
material in the A's Oort, but it seems much too dense for that."

Starplex continued to move in.  "Spectroscopy?"  asked Keith.

"Whatever those objects are," barked Jag, "they're non-luminous.

As for absorption of starlight from behind as it passes through the less
opaque parts, the spectra I'm seeing is typical of interstellar dust,
but there's much less absorption going on than I'd expect."  He turned
to face Keith.

"There's simply not enough light out here to see what's going on.  We
should send up a fusion flare."

"What if they are ships?"  asked Keith.  "Their crews might misconstrue
it--think we're launching an attack."

"They are almost certainly not ships," said Jag, curtly.

"They are planetssized bodies."

Keith looked at Rissa, at the holographic Thor.  and Rhombus, and at the
back of Lianne's head, to see if any of them had any objections.

"All right," he said.  "Let's do it."

Jag got up and walked over to stand beside Rhombus at the
external-operations station.  Keith found it funny watching them talk:
Jag barking like an angry dog, and Rhombus replying in shimmering
lights.  Since they were just conversing among themselves, PHANTOM
didn't bother to translate their words for Keith, but Keith tried to
listen in, just for the practice.  Waldahudar was a difficult language
for English speakers to follow, and it required a different grammatical
mood depending on the gender of the speaker and the person being spoken
to (males could only address females in a conditional/subjunctive way,
for instance).  On the other hand, specific nouns were avoided as much
as possible in polite Waldahudar, lest disagreements over terminology
ensue.  Throughout the conversation, Jag leaned on Rhombus's workstation
for support; his roedial limbs could be used for locomotion or
manipulation, but Waldahu-din didn't like dropping down onto their rear
four in the company of humans.

Finally, Jag and Rhombus had agreed on what characteristics the flare
should have.  Lianne at InOps issued an order that all windows on decks
one through thirty be covered or turned opaque.  She also drew the
protective covers over sensitive external cameras and sensors.

When that was done, Rhombus launched the flare--a ball about two meters
in diameter--out through a horizontal mass-driver tube that exited on
the outer rim of the central disk.  He let the flare get about twenty
thousand klicks above the ship and then ignited it.  The flare burned
with the light of a miniature sun for eight seconds.

Of course, it took the light from that flare almost twenty seconds to
reach the beginning of the phenomenon that was obscuring the background
stars.  It turned out that the phenomenon was roughly spherical,
measuring some seven million kilometers in diameter, so it took
twenty-four seconds--or three times the length of the light pulse--for
the illumination to pass through it in a circular band.  When it was
done, Rhombus summed the various illuminated parts of the image to give
a view of the whole thing as if it had been lit up simultaneously.  In
the all-encompassing hologram, the bridge crew could finally see what
was out there.

There were dozens of gray-and-black spheres, each one so dark that the
illuminated side was hardly much brighter than the unilluminated one.

"Each of the spheres is roughly the size of the planet Jupiter," said
Thor, his head bent down, consulting a readout.  "The smallest is
110,000 klicks wide; the largest, about 170,000.  They're clustered into
a spherical volume seven million klicks wide, or about five times the
diameter of Sol."

The individual orbs looked a lot like black-and-white photographs of
Jupiter, except that they didn't have neat latitudinal bands of cloud.

Rather, the clouds--or whatever it was that formed the visible surface
markings--seemed to swirl in simple convection cells from equator to
pole, the kind of pattern one might expect if the spheres had next to no
rotation.  In the intervening space between the world-sized spheres was
a diaphanous fog of gas or particles that formed a translucent haze;
doubtless this fog had been responsible for most of the twinkling effect
they'd observed.

The whole thing--spheres and surrounding fog--looked like assorted steel
ball bearings rolling around in a pile of black silk stockings.

How do they-- barked Jag, and Keith immediately knew what he was going
to say.  How could world-sized objects be packed so closely together?

There were perhaps ten diameters between the closest of the objects, and
fifteen or so between the ones that were least tightly packed.

Keith couldn't imagine any pattern of stable orbits that would keep them
from collapsing together under their own gravitational attraction.

If this was a natural grouping, it seemed unlikely that it could be an
old one.  Throwing some light on the subject had only made the mystery
deeper.

Chapter IV

On Earth, cells contain mitochondria for converting food to energy,
undulopodia (thrashing tails including those that propel sperm), and, in
plants, plastids for storing chlorophyll.

The ancestors of these organelles were originally independent
free-swimming creatures.  They came together in symbiosis with a host
being whose DNA is now walled off in the nucleus; to this day, some
organelles still contain vestigial DNA of their own.

On Flatland, diverse ancestors also learned to work together, but on a
much grander scale.  An Ib was actually a combination of seven large
life-forms--indeed, "Ib" is short for "integrated bioentity."

The seven parts are the pod, the watermelon-shaped creature containing
the supersaturated solution in which the crystals of the principal brain
grow; the pump, the digestive/respiratory structure that surrounds the
pod like a blue sweatshirt tied around a green pot belly, with tubular
arms hanging down for feeding and excreting; the twin wheels, fleshy
hoops coated with quartz; the frame, a saddle-shaped gray construct that
provides axles for the wheels and anchor points for the other elements;
the bundle, sixteen copper-colored ropes that normally form a heap in
front of the pump but can snake out as needed; and the web, a sensor net
that covers the pump, pod, and upper frame.

The web has an eye and a bioluminescent dot wherever two or more of its
strands intersect.  Although they have no speech organs, Ibs hear as
well as terrestrial dogs do, and they accept with good humor spoken
names bestowed by members of other races.  Starplex's ExOps manager was
Rhombus; Snowflake was senior geologist; Vendi (short for Venn Diagram)
was a hyperdrive engineer; and Boxcar--well, Boxcar was the biochemist
with whom Rissa was collaborating on the most important project in
history.

In 1972, Earth's Club of Rome began preaching the limits of growth.

But with all of space now at humanity's fingertips, there were no more
constraints.  To hell with the textbook 2.3 children.  If you wanted
2*10^3 kids, there was room enough for all of them--and for you, too.

The argument that individuals had to die in order to allow the race to
advance no longer applied.

Boxcar and Rissa were trying to increase the lifespans of the
Commonwealth races.  The problem was daunting; so much of how life
worked still remained mysterious.  Rissa doubted that the riddle of
aging would be solved in her lifetime, although within a century someone
would likely find the key.  The irony was not lost on her: Clarissa
Cervantes, senescence researcher, probably belonged to the final human
generation that would know death.

The average human lifespan was a hundred Earth years; Waldahudin lived
to be about forty-five (the fact that they were self-sufficient after
only six years didn't quite compensate for the shortness of their span;
some humans thought the knowledge that they were the shortest-lived of
the Commonwealth sentients was what made them so disagreeable); dolphins
were good for eighty years with proper health care; and, barring
accidents, an Ib would live for precisely 641 Earth years.

Rissa and Boxcar thought they knew why Ibs lived so much longer than the
other races.  Human, dolphin, and Waldahud cells all have a Hayflick
limit: they proper!y reproduce only a finite number of times.

Ironically, Waldahud cells had the highest limit--about ninety-three'
times--but their cells, like the creatures composed of them, had the
shortest life cycle.  Human and dolphin cells could divide about fifty
times: But the organelle clusters--there was no overall membrane to mike
them a single cell--that made up the body of an Ib could reproduce
indefinitely.  What eventually kills most Ibs is a mental short circuit:
when the crystals of the central brain, which form matrices at a
constant rate, reach their maximum information capacity, the overflow
causes the basic routines governing respiration and digestion to become
garbled.

Since she didn't seem to be needed on the bridge, Rissa had gone down to
her lab to join Boxcar.  She was sitting in a chair; Boxcar was
positioned next to her.  They watched the data scrolling up the monitor
plate rising from the desk in front of them.  The Hayflick limit had to
be governed by cellular timers of some sort.  Since it was observed in
cells from both Earth and Rehbollo, they'd hoped comparison genome
mapping would help.  Attempts to correlate across genetic platforms the
mechanisms for timing body growth, puberty, and sexual functions had all
been successful.  But, maddeningly, the cause of the Hayflick limit
remained elusive.

Maybe this latest test--maybe this statistical analysis of inverted
telomerase RNA codohs--maybe-- Lights winked on Boxcar's sensor web.

"It saddens me to note that the answer is not there," said the
translated voice, British, as all Ib voices were, and female, as half of
them were arbitrarily assigned.

Rissa let out a heavy sigh.  Boxcar was right; another dead end.

"I intend no offense with this comment," said Boxcar, "but I'm sure you
know that my race has never believed in gods.  And yet when I encounter
a problem like this--/

problem that seems, well, designed to thwart solution--it does make one
think that the information is being deliberately withheld from us, that
our creator does not want us to live forever."

Rissa made a small laugh.  "You may be right.  A common theme among
human religions is the belief that gods jealously guard their powers.

And yet why build an infinite universe, but put life on only a handful
of orlds.

"Begging your generous pardon for pointing out the obvious," said
Boxcar, "but the universe is only infinite in that it has no borders.

It does however contain a finite amount of matter.  Still, what is it
that your god is said to have commanded?  Be frui tful and multiply?"

Rissa laughed.  "Filling the universe would take an awful lot of
multiplying."

"I thought that was an activity you humans enjoyed."

She grunted, thinking of her husband.  "Some more than others."

"Forgive me if I'm being ' ' ,, intrusive, said Boxcar, "but PHANTOM
prefaced the translation of your last sentence with a glyph indicating
that you spoke it ironically.  It is doubtless me who is to blame, but I
seem to be missing a layer of your meaning."

Rissa looked at the Ib--a faceless, six-hundred-kilogram wheelchair.

Pointless to discuss such matters with her--with it, a sexless gestalt
that knew nothing of love or marriage, a creature to whom an entire
human lifespan was a brief interlude.  How could it understand the
stages a marriage went through--the stages a man went through.

And yet-- ' She could not talk about it with her female friends aboard
ship.  Her husband was Starplex's director--the .  . . the captain they
would have called it in the old days.  She couldn't chance gossip
getting around, couldn't risk diminishing him in the eyes of the staff.

Rissa's friend Sabrina had a husband named Gary.  Gary was going through
the same thing--but Gary was just a meteorologist.  Not someone to whom
everyone looked up, not someone who had to endure the gaze of a thousand
people.

I'm a biologist, thought Rissa, and Keith's a sociologist.

How did I ever end up a politician's wife, with him, me, and our
marriage under the microscope?

She opened her mouth, about to tell Boxcar that it was nothing, nothing
at all, that PHANTOM had mistaken fatigue or perhaps disappointment in
the latest experiment's results for irony.

But then she thought, why the hell not?  Why not discuss it with the Ib?

Gossiping was a failing of individual life-forms, not of gestalt beings.

And it would feel good--oh so very good--to get it off her chest, to be
able to share it with someone.

"Well," she said--an articulated pause, giving herself one last chance
to rein in her words.  But then she pressed on: "Keith is getting old."

A slight ripple of lights on Boxcar's web.

"Oh, I know," said Rissa, lifting a hand.  "He's young by Ibese
standards, but, well, he is becoming middle-aged for a human.  When that
happens to a human female, we undergo chemical changes associated with
the end of our childbearing years.  Menopause, it's called."

Lights playing up the web; an Ibese nod.

"But for male humans, it isn't so cut-and-dried.  As they feel their
youth slipping away, they begin to question themselves, their
accomplishments, their status in life, their career choices, and . . .
well, whether they are still attractive to the opposite sex."

"And is Keith still attractive to you?"

Rissa was surprised by the question.  "Well, I didn't marry him for his
looks."  That hadn't come out the way she'd intended.  "Yes, yes, he's
still attractive to me."

"It is doubtless wrong for me to remark upon this, and for that I
apologize, but he is losing his hair."

Rissa laughed.  "I'm surprised you would notice something like that."

"Without intending offense, please know that telling one human from
another is difficult for us, especially when they are standing close by
and so are visible to only part of our webs.  We're attentive to
individual details.  We know how upsetting it is to humans to not be
recognized by someone they think should know them.  I have noticed both
his loss of hair and its change of color.  I have learned that such
changes can signal a reduction in attractiveness."

"I suppose they can, for some women," said Rissa.  But then she thought,
this is silly.  Dissembling to an alien.  "Yes, I liked his looks better
when he had a full head of hair.  But it's such a minor point, really."

"But if Keith is still attractive to you, then--forgive my boundless
ignorance--I don't see what the problem is."

"The problem is that he doesn't care if he's still attractive to me.

Appealing to one's mate is taken as a given.  I suppose that's why men
in the past often put on weight after they'd gotten married.  No, the
question running through Keith's mind these days, I'm sure, is whether
he's attractive to other women."

"And is he?"

Rissa was about to respond with a reflex "of course," but then paused to
really consider the question--something she hadn't done before.

"Yes, I suppose he is.  Power, they say, is the ultimate aphrodisiac,
and Keith is the most powerful man in--in our space-going community."

"Then, begging forgiveness, what is the difficulty?  It sounds as though
he should have the answer to his question."

"The difficulty is that he may have to prove it to himself--prove that
he's still attractive."

"He could conduct a poll.  I know how much you humans rely on such
information."

Rissa laughed.  "Keith is more of... more of an empiricist," she said.

Her tone sobered.  "He may wish to conduct experiments."

Two lights winking.  "Oh?"

Rissa looked at a point high up on the wall.  "Whenever we're in a
social situation with other humans, he spends too much time with the
other women present."

"How much is too much?"

Rissa frowned, then said, "More than he spends with me.

And often, he's off talking to women who are half his age- half my age."

"And this bothers you."

"I guess so."

Boxcar considered for a moment, then: "But is this not all'

natural?  Something all men go through?"

"I suppose."

"One cannot fight nature, Rissa."

She gestured at the monitor, with the negative results of the last
Hayflick-limit study still displayed on it.  "So I'm beginning to find
out."

Chapter V

"Get me a sample of the material those spheres are made of," barked Jag,
standing up at his bridge station and.

looking at the director.  Keith gritted his teeth, and thought, as he
often did, of asking PHANTOM to translate Jag's words less directly,
inserting the human niceties of "please" and "thank you."

"Should we send a probe?"  Keith asked, looking at the Waldahud's
four-eyed face.  "Or do you want to go out yourself?."  If the latter,
thought Keith, I'd be glad to show you the airlock door.

"A standard atmospheric-sampling probe," said Jag.  "The gravitational
interplay between that many large bodies so close together must be
complex.  Whatever we send out might end up crashing into one of them."

All the more reason to send Jag, thought Keith.  But what he said was,
"A probe it is."  He turned and looked at the workstation positioned at
two o'clock to his own.  "Rhombus, please take care of that."

The Ib's web rippled assent.

"A delta-class probe would be most appropriate," said Jag, slipping back
into his chair and speaking now into a little hologram of Rhombus above
the rim of his console.

Keith tapped a key and joined the conference as well; a miniature
Waldahud head popped up in front of him next to the full body shot of
the Ib.  "How many spheres are there in total?"  asked Keith.

Rhombus's ropes operated controls.  "Two hundred and seventeen," he
said.  "But they all look pretty much the same, except for some
variation in size."

"Well, then, for an initial test, it doesn't make any difference which
sphere we sample," said Jag.  "Choose the one that presents the fewest
navigational difficulties.  First, scoop up some of that material that's
between the spheres.

Then buzz into one of the spheres and get me a sample of the gas, or
whatever it is that they're made of.  Take some from the top of the
clouds, and another sample from about two hundred meters down into the
clouds, if the probe can stand the pressure.  As you fill them, heat and
pressurize the sample compartments to match the ambient at the
collection points; I want to minimize chemical changes in the mateLights
moved up Rhombus's sensor web, and a few moments later he was launching
the probe.  He switched the control-room spherical display to the view
from the probe's cameras.  The stars that were behind the haze between
the spheres still seemed to be twinkling; the spheres themselves were
just circles of black against a backdrop that consisted of a starfield
and some faint blue nebulosity beyond.

"What do you think the spheres are?"  asked Rhombus, while the probe
closed toward its target.

Jag moved all four of his shoulders in a Waldahud shrug.

"Might be the remnants of a brown dwarf star that recently blew apart.

Any fluid will take on a spherical shape in zero-g, of course.  The
material in between will presumably eventually be swept up by the larger
bodies."

The probe was getting close to the material between the spheres.  "The
fog seems to consist of gas studded with solid particles averaging about
seven millimeters in diameter," said Rhombus, whose sensor web had
partially crawled onto the console in front of him so that he could read
the instruments more easily.

"What kind of gas?"  Keith asked.

"Its apparent molecular weight suggests a reasonably heavy or complex
compound," replied Jag, now looking at one of his monitors.  "However,
the absorption spectrum is that of normal space dust--carbon grains, and
so on."  A pause.  "There's no discernible magnetic field around the
spheres.  That's surprising; I had supposed the gas particles might have
been held in place by such fields."

"Will the probe be damaged by impact with the particles?"
asked Keith.

"It pleases me to respond in the negative," said Rhombus.

"I'm slowing the probe down to avoid that."

Part of the hologram was obscured as the hatch that covered the
atmospheric scoop opened up--bad design, that.  "Now collecting samples
of the material between the spheres," said Rhombus.  A few moments later
the view cleared as the hatch closed.  "Sample bay one full," the Ib
reported.  "Changing course for atmospheric skim."

The starfield wheeled around as the probe altered its trajectory.  One
of the circles of blackness was soon in the center of its view.  The
ebony sphere grew larger and larger until it dominated everything.  The
probe had headlights, which Rhombus had turned on.  They made two murky
shafts that penetrated a few meters into the dark, swirling material.

A different part of the view was obscured as another sample hatch
opened.

"Taking upper-atmosphere samples," reported the Ib, and then, a moment
later, "Sample container full."

"Adequate," said Jag.  "Now dive down two hundred meters--or however far
you can go safely--and get some more sphere material."

"Doing so, in harmonious peace," said Rhombus's clipped tones.

Everything was pitch-black, except for the twin pools of light from the
headlight beams.  They were now only penetrating a meter or so.  For one
brief moment, something solid seemed to be in the probe's path--an ovoid
shape the size of a dirigible--but it was gone from view almost at once.

"Depth now ninety-one meters," said Rhombus.  "Surprising.

External pressure is very light--far less than I'd have expected."

"Keep going down, then," said Jag.

The probe continued to descend.  Rhombus's web flashed in consternation.

"The pressure sensor must have been damaged--maybe an impact with a
piece of gravel.  I'm still reading almost no atmospheric pressure."

Jag lifted his upper shoulders.  "All right.  Fill a compartment here,
then bring it all home."

The third hatch did not obscure the camera at all, although its opening
probably shook the craft enough that had they been able to see anything
the view would have jiggled a bit.

"The internal-pressure gauge inside the sample compartment shows the
same almost-zero pressure the external gauge is indicating," said
Rhombus.  "Of course, they run through the same microprocessor.

Anyway, the compartment should have filled instantly, given that it was
a vacuum before the hatch opened."

Rhombus left the hatch open for a few more seconds, just to be sure,
then closed it, and turned the probe around, bringing it back to
Starplex.

Once the probe was back in its launching tube, its sample compartments
were disengaged and moved by robot arms onto conveyors, which took them
down to Jag's lab.  Jag, meanwhile, took an elevator there himself.

The containers plugged into jacks on the walls of the lab.

They didn't have to be opened; sensors and cameras could look inside
through the jacks.

Jag sat down in his chair--a real handcrafted Waldahud seat, not a
polychair--and activated the tall, thin monitors in front of him.  He
then keyed in a sequence of commands that selected a standard barrage of
tests, and watched with growing amazement as the results appeared on his
screens.

Spectroscopy: negative findings.

Electromagnetic sweep: negative findings.

Beta decay: none.

Gamma-ray emissions: none.

Screen after screen lit up: negative findings; none; negative findings;
none.

He tapped a key, and the scale beneath the testing bay read off the mass
of the sample container: 12.782 kilograms.

"Central Computer," called Jag into the air.  "Check the spec sheet for
this sample container.  How much does it mass when empty?"

"The container's mass is 12.782 kilograms," barked PHANTOM in
Waldahudar.

Jag swore.  "The fardint thing is empty."

"Correct," said PHANTOM.

Jag tapped a key, and a hologram of Rhombus appeared.

"Teklarg," said Jag, calling the Ib by his name in Waldahu-dar, "that
probe you sent out was defective.  All of the sample material from its
number-two container leaked out on the way back."

"Sincere apologies, good Jag," said Rhombus.  "I submit to punishment
for wasting your time, and will dispatch a replacement at once."

"Do so," said Jag, and he stabbed the button that cut off
communications.  He turned his attention to the number-one sample
container .  . . and was shocked to discover that it, too, had leaked
out its contents on the way back.  "Shoddy human engineering," he
grumbled to himself.

But he was grumbling even more once the second probe's sample containers
had been conveyed to his lab.  The readings were the same--including the
anomalously low air-pressure readings after it had dived into the large
sphere.

Once again, Jag summoned up a hologram of Rhombus.

"I say with all peaceful good wishes, dear Jag, that there does not
appear to be anything wrong with either probe.  The container seals are
perfect.  Nothing should have been able to leak out."

"Regardless, whatever samples we are collecting are getting out," said
Jag.  "Which means .  . . well, which means that whatever the samples
are made of must be unusual stuff indeed."

Lights moved up Rhombus's web.  "A fair assumption."

Jag slid his dental plates together.  "There must be a way to bring some
of that material aboard for study."

"Doubtless you have already thought of this," said Rhombus, "and I waste
both our time by mentioning the idea, but we could use a force box.  You
know, like the kind they use in labs for handling antimatter."

Jag lifted his upper shoulders.  "Acceptable.  But don't use an EM
forcefield; instead, use artificial-gravity fields to hold the contents
away from the box's walls, regardless of what acceleration we use."

"Will do, with obeisance," said Rhombus.

The force box was manipulated by tractor beams.  It consisted of eight
antigrav generators arranged as the corners of a perfect cube, with
wide, paddlelike handles sticking off each face's midpoint to give the
tractors something to hold on to.  The box was pushed into one of the
large gray spheres, and opened there.  A second box was manipulated into
the swarm of gravel between two of the spheres and activated there.  The
two boxes were then quickly hauled back in to Starplex.

Finally, the sample containers were maneuvered into separate isolation
chambers in Jag's lab.  The antigrav trick had been a success: one box
did indeed contain samples of the gas that constituted the sphere, and
the other held several pieces of translucent gravel plus one partially
transparent rock the size of a hen's egg.  Now, at last, Jag would find
out what they were dealing with.

Chapter VI

Keith ran a hand over his pate, and leaned back in his chair, looking
out at the starscape hologram enveloping the bridge.  There wasn't much
else to do, until Jag reported back.  Rissa was still off working with
Boxcar, and alpha shift was coming to an end.  Keith exhaled--probably
too noisily.  Rhombus had rolled up to the director's workstation to
discuss something or other.  Lights flashed across the Ib's mantle.

"Irritated?"  said his translated voice.

Keith nodded.

"Jag?"  asked the Ib.

Keith nodded again.

"In politeness, I observe that he's not that bad," said Rhombus.  "As
Waldahudin go, he's positively genteel."

Keith gestured toward the part of the starfield that hid the door Jag
had gone through.  "He's so .  . . competitive.

Combative."

"They're all like that," said Rhombus.  "All the males, anyway.  Have
you spent much time on Rehbollo?"

"No.  Although I was in on the first contact between humans and
Waldahudin, I always thought that it was best for me to stay away from
Rehbollo.  I--I've still got a lot of anger over the death of Saul
Ben-Abraham, I guess."

Rhombus was quiet for a few moments, perhaps digesting this.  Then his
web rippled with light again.  "Our shift is over, friend Keith.  Will
you grant me nine minutes of your time?"

Keith shrugged and got to his feet.  He addressed the room.  "Good work,
everyone.  Thank you."

Lianne turned around, her platinum hair bouncing as she did so, and
smiled at Keith.  Rhombus and Keith headed out into the chilly corridor,
the Ib rolling beside the human.

A couple of slim robots were moving down the corridor as well.  One was
carrying a lunch tray for someone; another was running a vacuum cleaner
along the floor.  Keith still privately thought of such robots as
PHARTs--PHANTOM ambulatory remote toilers--but the Waldahudin had
started throwing things when it was suggested that Starplex terminology
contained acronyms nested within acronyms.

Through a window in the corridor wall, Keith could see
one of the vertical dolphin-access tubes, consisting of meter-thick
disks of water separated by ten centimeters of air held in place by
force fields.  The air gaps prevented the water pressure from increasing
over the tube's height.  As he watched,-a bottle-nosed dolphin passed
by, swimming up.

Keith looked at Rhombus.  Lights wexe flashing in unison on his web.

"What's so funny?"  Keith asked.

"Nothing," said the Ib.

"No, come on.  What is it?"

"I was just thinking of a joke Thor told today.  How many Waldahudin
does it take to change a lightbulb?  Answer: five--and each one has to
get credit."

Keith frowned.  "Lianne told you that same joke weeks ago."

"I know," said Rhombus.  "I laughed then, too."

Keith shook his head.  "I'll never understand how you Ibs can find the
same thing funny over and over again."

"I'd shrug if I could," said Rhombus.  "The same painting is pretty each
time you look at it.  The same dish is tasty each time you eat it.

Why shouldn't the same joke be funny each time you hear it?"

"I don't know," said Keith.  "I'm just glad I got you to stop telling me
that stupid 'that's not my axle--it's my feeding tube' joke every time
we met.  That was irritating as hell."

"Sorry."

They continued down the corridor in silence for a while, then: "You
know, good Keith, it's a lot easier to understand the Waldahudin if
you've spent time on their world."

"Oh?"

"You and Clarissa have always been happy together, if you'll permit me
to say so.  We Ibs don't have such intimacy with other individuals; we
shuffle our own genetic material amongst our component parts, rather
than bonding with a mate.  Oh, I take comfort from my other
components--my wheels, for instance, are not sentient, but they have
intelligence comparable to that of a terrestrial dog.  I have a
relationship with them that gives me great joy.  But I perceive that the
relationship you enjoy with Clarissa is something much, much more.

I only dimly understand it, but I'm sure Jag appreciates it.

Waldahudin, like humans, have two sexes, after all."

Keith couldn't see where this was going, and, on the whole, thought
Rhombus was presuming on their friendship.

"Yes?"

"Waldahudin have two sexes, but they do not have equal numbers of each
sex," said the Ib.  "There are, in fact, five males for every female.

Yet, despite this, they are a monogamous race, forming lifetime
pairbonds."

"So I've heard."

"But have you contemplated the ramifications of thatT' asked the Ib.

"It means that four out of every five males end up without a mate--end
up being excluded from the gene pool.  Perhaps you had to fend off some
other suitors in your pursuit of Clarissa--or maybe she had to fend off
others who were pursuing you; forgive me, but I've no idea how these
things work.  But I imagine in such contests it was a comfort to all the
participants to know that for each male there was a female, and vice
versa.  Oh, the pairings might not end up as one might wish, but the
chances were good that each man would find a woman, and vice versa--or a
mate of their own gender, if that was their preference."

Keith moved his shoulders.  "I suppose."

"But for Jag's people, that is not the case.  Females have absolute
power in their society.  Every single one of them is--courted, I believe
is the word--by five males, and the female, when she reaches estrus at
thirty years of age, will pick her one mate from the five who have spent
the last twenty-five years vying for her attentions.  You know Jag's
full name?"

Keith thought for a moment.  "Jag Kandaro em-Pelsh, isn't it?"

"That's right.  Do you know its derivation?"

He shook his.  head.

"Kandaro is a regional designation," said Rhombus.  "It refers to the
province Jag traces lineage to.  And Pelsh is the name of the female of
whose entourage he is a member.

She's quite a significant power on Rehbollo, actually.  Not only is she
a famous mathematician, she's also a niece of Queen Trath.  I met Pelsh
once, while attending a conference.

She's charming, intelligent--and about twice Jag's size, as are all
adult Waldahud females."

Keith contemplated a mental picture, but said nothing.

"Do you see?"  asked Rhombus.  "Jag has to make his mark.  He has to
distinguish himself from the other four males in her entourage if he is
to be chosen.  Everything a premating Waldahud male does is geared
toward making him stand out.  Jag came aboard Starplex looking for glory
enough to earn him Pelsh's affection .  . . and he's going to find that
glory, no matter how hard he has to push."

That night, lying in bed, Keith rolled onto his back.

All his life, he'd had trouble sleeping--despite the advice people had
given him over the years.  He never drank caffeinated beverages after !
1800.  He had PHANTOM play white noise through the bedroom speakers,
drowning out the sound of Rissa's occasional snoring.  And although
there was a digital-clock display built into his night table, he'd
covered its readout with a little square of plastic card slipped into a
join between the pieces of wood composing the table.

Staring at a clock, worrying about how late it was, about how little
sleep he was going to get before morning came, was counterproductive.

Oh, he could see the clock face when standing in the bedroom, and he
could always reach over and bend down the plastic card to look at it in
bed if he was really curious, but it helped.

Sometimes, that is.

But not tonight.

Tonight, he tossed and turned.

Tonight, he relived the encounter in the corridor with Jag.

Jag.  Perfect name for the bastard.

Keith rolled onto his left side.

Jag was currently running a series of professional-development seminars
for those Starplex staff members who wanted to know more physics; Rissa
was running a similar series for those who wanted to learn some more
biology.

Keith had always been fascinated by physics.  Indeed, while taking a
range of sciences in his first year at university, he'd thought
seriously about becoming a physicist.

So much neat stuff--like the anthropic principle, which said that the
universe had to give rise to intelligent life.  And Schredinger's cat, a
thought experiment that demonstrated that it was the act of observing
that actually shaped reality.  And all the wonderful twists and turns to
Einstein's special and general theories of relativity.

Keith loved Einstein--loved him for his fusion of humanity and
intellect, for his wild hair, for his own knight-errant quest to try to
put the nuclear genie he'd made possible back into the bottle.  Even
after choosing sociology as his major, Keith had still kept a poster of
the grand old man of physics on his dorm wall.  He would enjoy taking
some physics seminars .  . . but not with Jag.  Life was too short for
that.

He thought about what Rhombus had said about Waiclud family life--and
that turned his mind to his older sister Rosalind and younger brother
Brian.

In a way, Roz and Brian had shaped him as much as his genetic makeup
had.  Because they existed, he was a middle child.  Middle children were
the bridge-builders, always trying to make connections, to bring groups
together.  It had always fallen to Keith to organize family events, such
as parties for their parents' milestone anniversaries and birthdays, or
Christmas gatherings of the clan.  And he'd organized his high-school
class's twentieth reunion, thrown receptions in his home for colleagues
visiting from out of town, supported multicultural and ecumenical
groups.  Hell, he had spent most of his professional life working to get
the Commonwealth off the ground, the ultimate exercise in
bridge-building.

Roz and Brian didn't worry about who liked them and who didn't, about
whether there was peace between all parties, about networking, about
whether people were getting along.

Roz and Brian probably slept well at nights.

Keith switched back to lying on his spine, an arm behind his head.

Maybe it was impossible.  Maybe humans and Waldahu-din could never get
along.  Maybe they were too different.

Or too similar.  Or .  . .

Christ, thought Keith.  Let it go.  Let it go.

He reached over, bent down the piece of plastic card, and looked at the
glowing, mocking red digits.

Damn.

Now that they had collected samples of the strange material, it fell to
Jag and Rissa, as the two science-division heads, to come up with a
research plan.  Of course, the next step depended on the nature of the
samples.  If it turned out to be nothing special, then Starplex would
continue its quest for whoever activated this shortcut--a life-sciences
priority mission.  But if the strange material was out of the ordinary,
Jag would argue that Starplex should stay here to study it, and Rissa's
team should take one of Starplex's two diplomatic vessels--either the
Nelson Mandela or the Kof Dagrelo em-Stalsh--to continue the search.

The next morning Jag used the intercom to contact Rissa, who was up in
her lab, saying he wanted to see her.  That could mean only one thing:
Jag was intending a preemptive strike to set mission priorities.  She
took a deep breath, preparing for a fight, and headed for the elevator.

Jag's office had the same floor plan as Rissa's, but he'd decorated
it--if that was the word--in Waldahud mud-art.

He had three different models of polychairs in front of the desk.

Waldahudin disliked anything that was mass-produced; by having different
models he could at least give the appearance that each was one of a
kind.  Rissa sat in the polychair in the middle and looked across Jag's
wide, painfully neat desk at him.  "So," she said.

"You've presumably analyzed the samples we collected yesterday.  What
are the spheres made of?."

The Waldahud shrugged all four shoulders.  "I don't know.  A small
percentage of the sample material is just the regular flotsam of
space-carbon grains, hydrogen atoms, and so on.  But the principal
material is eluding all standard tests.  It doesn't combust in oxygen or
any other gas, for instance, and as far as I can tell it has no
electrical charge at all.  Regardless of what I try, I can't knock
electrons off it to get positively charged nuclei.  Delacorte up in the
chemistry lab is having a look at a sample now."

"And what about the gravel from between the spheres?"

Rissa asked.

Jag's bark had an unusual quality.  "I'll show you," he said.  They left
his office, went down a corridor, and entered an isolation room.

"Those are the samples," he said, gesturing with a medial ann at a
glass-fronted cubic chamber measuring a meter on a side.

Rissa looked through the window and frowned.  "That big one--does it
have a flat bottom?"

Jag peered through the window.  "Gods--"

The large egg-shaped piece of material had sunk about halfway into the
bottom of the chamber, so that only a domelike part stuck up.  Peering
more closely, Jag could see that some of the smaller gravel pieces were
sinking, too.

He pointed with his upper-left first finger as he counted the fragments.

Six were gone, presumably sunk beneath the surface of the chamber's
bottom.  But no holes had been left in their wake.

"It's dropping right through the floor," said Jag.  He looked at the
ceiling.  "Central Computer!"

"Yes?"  said PHANTOM.

"I want zero-g inside that sample chamber now!"

"Doing so."

"Good--no, wait.  Change that!  I want five standard gees in there,
but-I want them coming from the chamber's ceiling, not its floor.  Got
that?  I want gravity in there to pull objects up toward the roof."

"Doing so," said PHANTOM.

Rissa and Jag watched, fascinated, as the egg-shaped piece of material
started to rise out of the bottom of the chamber.  Before it was all the
way out, pieces of gravel welled up from beneath the solid floor and
fell up toward the ceiling, hitting it not with the ricochet bounce one
would expect but more like pebbles falling into tar and beginning to
sink.

"Computer, oscillate the gravity until all the objects are free from the
floor and ceiling, then shift to zero-g, with the objects floating in
the chamber."

"Doing so."

"My word, that's incredible," said Rissa.  "The stuff can pass right
through other matter."

Jag grunted.  "The original samples we tried to collect must have leaked
through the probes' walls, pushed out by the force of their acceleration
toward Starplex."

By bouncing the apparent source of gravity inside the chamber between
the top and the bottom, PHANTOM eventually got all the gravel pieces to
float freely.  But Jag's fur danced when he saw the results of two
pieces moving together.  He'd expected to see them hit, then bounce off.

Instead, when they got to just a few millimeters apart they deflected
away from each other.

"Magnetic," said Rissa.

Jag moved his lower shoulders.  "No, there's no magnetism at work here
--there are no charges present."

There were four articulated arms ending in tractor-beam emitters inside
the chamber, and Jag operated all of them in unison, controlling one
with each hand.  He used one beam to lock onto a piece of translucent
gravel a centimeter in diameter, and used a second beam to grab another
piece of equal size.  He then operated the controls to move the two
pieces together.  Everything went fine until the chunks were within a
very short distance of each other, but then no matter how much power he
fed into the tractor beams, he was unable to bring them any closer.

"Amazing," said Jag.

"There's some sort of force repelling them--a nonmagnetic repulsive
force.  I've never seen anything like it."

"That must be what keeps the haze of gravel from coalescing," said
Rissa.

Jag lifted his upper shoulders.  "I suppose.  The net effect is that the
material in the haze between the spheres is bound together
gravitationally, but it won't ever coalesce more than it already has."

"But then what keeps these pebbles together?  Why doesn't that repulsive
force blast them apart?"

"They must be locked chemically.  I suspect they were originally formed
under great pressure--pressure that defeated the repulsion we're
observing.  Now that their constituent atoms are bonded, they stay
together, but it would take great effort to combine the pebbles into
bigger groupings."

"Oh, hell," said Rissa.  "You know what I'm thinking .  . ."

Jag's four eyes went wide.  "The Slammers!  We've only ever seen what
their weapon did to one of our probes.

Perhaps if they turned it on a world, this might be the result.

Quite the doomsday device: not only does it destroy the planet, but it
also imparts a force to the rubble to prevent it from ever collecting
back together to form another world."

"And now there's an open shortcut leading from here to the Commonwealth
worlds.  If they were to come through--"

At that moment, Jag's wall beeped, and the elderly face of Cynthia
Delacorte appeared on it.  "Jag, it's--oh, hi, Rissa..

Listen, thanks for sending up those samples.  Do you know that this
stuff sinks into normal matter?"

Jag lifted his upper shoulders.  "Incredible, isn't it?"

Delacorte nodded.  "I'll say.  It's not normal baryonic matter.  It's
not antimatter, of course.  We'd have been blown out of the skies if it
were.  But where normal protons and neutrons consist of combinations of
down quarks and up quarks, this stuff is made of matte quarks and glossy
quarks."

Jag's fur danced excitedly.  "Really?"

"I've never heard of those kinds of quarks," said Rissa.

Jag made a sound like she was a fool, but Delacorte nodded.  "Since the
twentieth century, humans have known of six flavors of quarks--up, down,
top, bottom, strange, and charmed.  In fact, six was the maximum number
allowed for under the old Standard Model of physics, so we'd pretty much
given up looking for more, which turned out to be a big mistake."  She
looked pointedly at Jag.  "The Waldahudin had only found the same six
flavors, too.  But when we met the Ibs, they were aware of two more,
which we refer to by opposing lusters, glossy and matte.

There's no way you can get them by breaking down normal matter,' but the
Ibs had 'done unique work pulling matter out of quantum fluctuations.

In their experiments, luster quarks were sometimes produced, but only at
very, very high temperatures.  What we've got here are the first-known
naturally occurring luster quarks."

"Incredible," said Jag.  "You've noticed thefardint things carry no
charge?  What explains that?"

Delacorte nodded, then looked at Rissa.  "Electrons have a charge of
negative one unit, up quarks have a positive two-thirds charge, and down
quarks have a negative one-third charge.  Each neutron is made of two
downs quarks and an up, which means the net charge is zip.

Meanwhile, each proton consists of one down and two ups, which gives a
charge of positive one.  Since atoms have equal numbers of protons and
electrons, they have an overall neutral charge."

Rissa understood that the explanation had been for her benefit.  She
nodded at the wall monitor for Delacorte to go on.

"Well, this luster-quark matter consists of what I'm calling
para-neutrons and para-protons.  Para-neutrons consist of two glossy
quarks and one matte, and para-protons consist of a pair of mattes plus
a glossy.  But neither glossies nor mattes carry any charge
whatsoever--so regardless of how you combine them, there's no charge on
the nucleus.

And without a positive nucleus, there's nothing to attract negatively
charged electrons, so a luster-quark atom is solely a nucleus; it has no
electron orbital shells.  The bottom line is that luster matter isn't
just electrically neutral.  Rather, it's nonelectrical; it's immune to
electromagnetic interactions."

"Gods," said Jag.  'q'hat would explain why it can sink into solid
objects.  It would probably pass through completely unhindered if it
weren't for drag caused by the regular-matter carbon grains and hydrogen
polluting it, and--of course!  That explains why we can see it, too.  If
it were purely luster quarks, it would be invisible, since the
reflection and absorption of light depend on vibrating charges.

We're just seeing the interstellar dust that's caught gravitationally
inside the luster matter, like sand in jelly."

He looked at the wall screen.  "All right--it doesn't interact
electromagnetically.  What about the nuclear forces?"

"It is affected by both the strong and the weak nuclear force," said
Delacorte.  "But those forces are so short-range, I doubt we'd get any
interaction through them with regular matter except at incredibly high
pressures and temperatures."

Jag was quiet for a moment, considering.  When he next spoke, his
barking was subdued.  "It's incredible," he said.

"We knew the Slammer weapon could break chemical bonds, but changing
regular matter into luster matter is --"

**DELTA DRACONIS**

"What was Saul Ben-Abraham like ?"  asked Glass.

Keith looked around the forest simulation, thinking of all the ways he
could describe the man who had been his best friend.  Tall.

Boisterous.  A guffaw that could be heard a kilometer away.  A guy who
could identify any song in three notes.  A man who could drink more beer
than anyone Keith had ever met--he must have had a bladder the size of

Iceland.  Finally, Keith settled on, "Hairy."

"I beg your pardon?"  said Glass.

"Saul had a great beard," said Keith.  "Covered most of his face.  And
he had this one giant eyebrow, like a chimp had laid its forearm across
his head.  The first time I ever saw him in shorts, I was amazed.  The
guy looked like sasquatch."

"Sasquatch?"

"A mythical primate from my part of Earth.  I still remember seeing him
in shorts for the first time and saying, gee, Saul, you've got hairy
legs.  He let out that great laugh of his and said, 'Yes--like a man.'"
I said it was more like ten men."  Keith paused.  "God, how I miss him
Friends like that, who mean that much to you, come along perhaps once in
a lifetime."

Glass was quiet for several seconds.  "Yes," he said at last.  "I
suppose that's true."

"Of course," said Keith, "there was more to Saul than just a thick coat
of fur.  He was brilliant.  The only person I've ever met who I thought
might be brighter than him is Rissa.  Saul was an astronomer.  He's the
person who discovered the Tau Ceti shortcut, from its footprint in
hyperspace.  The guy should have won a Nobel prize for that .  . . but
they don't like to award them posthumously."

"I appreciate your loss," said Glass.  "It's as if--oh, excuse me.  My
reckoner says I've got an incoming thought package.  Will you excuse me
for a little while?"

Keith nodded, and Glass took an odd step, sort of sideways, and
disappeared.  Doubtless he'd gone through a door hidden by the forest
simulation filling the docking hay--the only direct visual evidence
Keith had had that he wasn't actually back on Earth.  Well, if there was
a door, Keith wanted to find it.  He patted the air in the spot that
Glass had disappeared from, but there was nothing.

There had to be a wall somewhere around, though.  The bay wasn't that
big.  Keith began to walk, figuring he was bound to hit a wall
eventually.  He continued on for perhaps five hundred meters without
encountering any obstruction.

Of course, if his--he started to think the word "captor," again, but
fought it down and substituted "host" instead--if his host were being
clever, he could have manipulated the images to make.Keith think he was
walking in a straight line when he was really going in a circle.

Keith decided to rest.  As much as he tried to find time to work out in
Starplex's Earth gym, which had gravity set to a full standard gee, he'd
lost some muscle tone because of all the time he spent in the lighter
Wald-standard gravity used in the ship 's common elements.  He really
should take Thor Magnor up on his offer of playing handball; Keith and
Saul had played the game regularly, but he'd given it up when Saul had
died.

Keith lowered himself to the ground again, which, at this spot, was
covered with clover.  Keith found it quite comfortable to sit on.  He
ran his hand through the clover, enjoying the feel of it against his
skin, and looked around.  It was a remarkable Simulation, he thought.

So relaxing, so beautiful.

He watched some birds moving high overhead, but they were too far away
for him to identify the species.

Keith plucked a piece of clover and brought it up to look at.  Maybe
this was his lucky day; maybe he'd find a four-leaf clover .  . .

What luck. He did.

He plucked a few more pieces, and his jaw dropped.

He pressed his face to the ground, and examined plant after plant.

They were all four-leaf clovers.

He brought one up to his face, held between thumb and index finger, and
scrutinized it.  It seemed like normal clover in almost every way.  It
even bled a little green plant juice from its severed stem.  But each of
these clovers had four leaves.  Keith remembered from undergraduate
botany that the genus name for clover was Trifolium-- three leaves.  By
definition, clover had three leaves, except in the odd mutant
individual.  But these plants all had four distinct oval leaves.

Keith looked at the white and pink flowers growing from some of the
plants.  Definitely clover--but four-leaf clover.

He shook his head.  How could Glass have gotten all the 'other details
right, but have made a mistake such as this?  It didn't make any sense.

He looked around again, searching for any other discrepancies.

Most of the deciduous trees did indeed seem to be maple--sugar maple, in
fact, if he wasn't mistaken.  And those conifers were jack pine, and the
big one a little farther along was a blue spruce.  And-- And what kind
of bird was that?  Sitting in that blue spruce?  Surely not a cardinal
or ajay.  Oh, it had the tufted head crest, but it was emerald green,
and its bill was flat and spatulate, unlike that of most songbirds.

It was Earth; no doubt about it.  That was Earth's moon, still sitting
high in the daytime sky.  And yet, it wasn't quite Earth--some of the
details weren't right.

Keith chewed at his lower lip, puzzled .  . .

Chapter VII

Jag and Rissa took an elevator up to the bridge, and soon the Waldahud
was standing in front of the two rows of workstations, telling his
colleagues of the fantastic discovery.

"There's a metaphor that's been carried by the current for years," he
barked, "that visible matter is just froth on an inky ocean of dark
matter.  We knew the dark matter was there because of its gravitational
effects, but we've never seen it until now.  Those spheres out there,
and the gravel fog between them, are made out of dark matter."

Lianne let out a low whistle.  Keith raised an eyebrow.  He knew a bit
about dark matter, of course.  CalTech astronomer Fritz Zwicky had
deduced its existence back in 1933, through observations of the galaxies
in the Virgo Cluster.

Those galaxies were rotating around each other so quickly that if the
visible stars were the only major source of mass present, the whole
thing should have flung apart long ago.  Subsequent studies showed that
almost every large structure in the universe--including our Milky Way
galaxy--behave as if there were far more mass present than could be
accounted for by the suns and any reasonable number of attendant
planets.  Some previously undetected matter, dubbed "dark matter"
because it was apparently neither luminous nor highly reflective,
accounted for over 90 percent of the gravity in the universe.

As usual, Thorald Magnor had his large feet up on his console, and his
thick fingers interlaced behind his head, buried in his red hair.  "I
thought we'd already discovered what dark matter was," he said.

"Only part of it," said Jag, lifting two of his four hands.

"We've long known that baryonic matter--matter made up of protons and
neutrons--accounts for less than ten percent of the mass of the
universe.  In 2037, we discovered that the ubiquitous tau neutrino has a
very slight mass--about seven electron volts' worth.  And we found that
the muon neutrino also has a trifling mass, about three one-thousandths
of an electron volt.  Since these two types of neutrinos are so
abundant, in total they account for about three or four times more mass
than all the baryons do.  But that still left us with as much as two
thirds of the universe's mass unaccounted for--until now."

"What makes you think the stuff out there is dark ' matter?"  Keith
asked.

"Well," said Jag, "it isn't normal matter; that much is certain."

Although he was trying to hide it, Jag was holding on to the beveled
edge of Thor's console with one hand so that he wouldn't drop down onto
four legs.  Starplex operated on a four-shift cycle as a concession to
the Waldahudin, who came from a world with a short day, but Jag had been
working overtime.  "In early dark-matter studies, there were two
candidates for the material composing it, named WIMPs and MACHOs by
human astronomers-- all of whom should have to swim in a river of urine,
by the way.  WIMPs are 'weakly interacting massive particles' -you see
the gibberish foisted upon us in search of these silly acronyms? Anyway,
the tau and muon neutrinos turned out to be WIMPs."

"And MACHOs?"  asked Keith.

"'Massive compact halo objects,'" said Jag.  "The 'halo' is the sphere
of dark matter that has a galaxy at its center.

The 'massive compact objects' were thought to be billions of
Jupiter-sized bodies not associated with any particular star--a fog of
gaseous worlds through which the luminous material of the galaxy moves."

Lianne was leaning forward, chin resting on her hand.  "But if the
universe really were permeated with--with MACHOs," she asked, "wouldn't
we have detected them by now?"

Jag turned to her.  "Even Jupiter-sized objects are puny on the cosmic
scale.  And since they're nonluminous, the only way we would see them is
if one wandered in front of a star we happened to be observing.

Still, the effect would be minor: just a slight gravitational lensing of
the star's light, causing a temporary brightening.  Such events have
occasionally been seen; the oldest recorded observation of one was made
by human astronomers in 1993.  But even if space were lousy with
MACHOs--enough so that they made up two thirds of all the mass in the
universe--only one out of every five million stars you could observe at
any given moment would likely be undergoing gravitational lensing due to
one passing by."  He gestured toward the twinkling part of the
starfield.  "We only see gross effects here because we're so close to
the field of dark matter, and because the dark matter itself is
transparent.

We're actually just seeing regular space dust, sprinkled throughout the
dark-matter objects."

Keith looked at Rissa, his eyebrows raised.  She made no objection.

"Well," said the director, "this certainly seems to be a major
discovery, worthy of further--"

"Forgive the interruption," said Rhombus, "but I'm detecting a tachyon
pulse."  Rhombus rotated the starfield hologram surrounding the bridge
to bring the shortcut front and center; the effect on Keith's stomach
was similar to what he experienced in a planetarium when the operator
was trying to demonstrate that learning could be fun.  Jag quickly took
his seat on Keith's left.  The shortcut was a pinprick of green--the
color of whatever was coming through it--surrounded by the usual ring of
violet Soderstrom radiation.

"Is it a Commonwealth ship?"  Keith asked.

"No," said Rhombus.  "There's no transponder signal of any kind."  The
green spot continued to grow.  "Incredulous: that is bright"--PHANTOM's
stilted translation of the words that were flashing over Rhombus's
mantle.  But the Ib was right.  The shortcut was the brightest object in
the sky?

exceeding even the A-class star Jag had spotted earlier.

"Let's give it lots of room, whatever it is," said Keith.

"Thor, start backing us away."

"Doing so."

Keith looked to his left.  "Jag, spectral analysis."

The Waldahud read from one of his monitors.  "Scanning.

Hydrogen, helium, carbon, nitrogen, oxygen, neon, magnesium, silicon,
iron .  . ."

"It looks pure green," said Keith.  "Could it be a laser?"

Jag turned his two right eyes to look at the director, while keeping his
other two focused on his instruments.  "No.

There's nothing coherent about that light."

The fiery green pinprick was growing wider; it had become a fiercely
bright circle several meters in diameter.

"How about a fusion exhaust?"  asked Lianne.  "Could it be a ship coming
out of the shortcut tail first, as if it were decelerating?"

Jag consulted more readouts.  "It certainly is a fusion signature," he
said.  "But it would have to be a very powerful engine."

Keith left his console and walked over to stand just behind Rhombus.

"Any chance of contacting that ship?"

One of Rhombus's manipulatory ropes whipped out to touch a control.

"Forgive me, but not on conventional radio.

The thing is putting out an enormous 'amount of EMI.  A hyperspace radio
link might work, but there's no way of knowing which quantized level
they use for communication."

"Start at the lowest and work your way up," Keith said.

"Standard prime-number sequences."

Another flick of a rope.  "Transmitting.  But it would literally take
forever to try every level."

Keith turned around and faced Rissa.  "Looks like you might get your
first-contact opportunity after all."  He turned back to look at the
shortcut.  "Christ, that's bright."  Every object on the bridge that
wasn't swathed in the hologram was bathed in green light now.  Although
no shadows fell on the invisible floor, the staff members were all
casting harsh ones on the seating gallery behind the workstations.

"It's even brighter than it looks," said Jag.  "The camera is filtering
most of it."

"What the hell could it be?"  Keith asked, looking at Jag.

"Whatever it is," said Jag, "it's streaming out a lot of charged
particles--could be a particle-beam weapon."  The green circle continued
to expand.  "Diameter is now one hundred and ten meters," said Jag. "One
fifty."  His barking grew softer, incredulous.  "Two fifty.  Five
hundred.  A full kilometer.  Two kilometers."

Keith turned back to the flaring image in the hologram.

"Jesus," he said, bringing an arm up to shield his eyes.

Slapping of ropes from Rhombus--an Ibese scream.

"Profuse apologies," he said a moment later as the display darkened
somewhat.  "The object is brighter than the automatic compensators are
designed to deal with.  I shall henceforth monitor the display
directly."

The green circle kept expanding at a great rate.  Its edges were
coruscating with violet Soderstrom discharges--a pyrotechnical halo
around the vast green center.  The central area still seemed to be a
flat cimle.

"Temperature is about twelve thousand Kelvin," said Jag.

"That's hot," said Rissa.  "What in God's name is it?"

An alarm started sounding, warbling high and low.

"Radiation warning!"  shouted Lianne.  She wheeled to face Keith.

"Recommended action: move Starplex."

"Right," Keith said, sprinting back to his command station.  "Thor, pick
up the pace.  Put us another fifty thousand klicks from the shortcut."

He glanced at his astrogation readout.  "Course two hundred and ten
degrees by forty-five degrees.  Use thrusters only; I don't want to drop
into hyperspace until we know what that thing is."

"As you say, boss," said Thor, hands flying over his instruments.

The apparent growth of the green circle slowed, but it was still getting
larger; its expansion rate was exceeding Star-plex's maneuvering speed.

"I didn't know a shortcut could open that wide," said Rhombus.  "Jag,
just what exactly is coming through it?"

Both sets of Jag's shoulders rose and fell.  "Unknown.  The spectral
analysis is unusual--lots of heavy-element Fraunz hofer absorption
lines.  It matches nothing in our database."  He paused.  "If it's a
fusion exhaust, the ship must be gigantic."

"It looks perfectly flat," said Rissa.  "How can it keep expanding as a
circle?"

"The apparent expansion is caused by the opening up of the shortcut
aperture," said Jag.  "They open at a finite speed, and, when touched by
a flat surface, an aperture will take on a circular shape.until the
edges are reached."  He used his left eyes to glance at a readout.

"The rate at which the aperture is opening is increasing, although at an
uneven rate."

The halo of violet, representing the edges of the portal, was just the
faintest border around the vast circle, like a matte line around a
spaceship model in an old-fashioned SF movie.

"How big is it now?"  Keith asked.

Jag was evidently getting tired of answering that question.

He touched keys on his console and a trio of color-coded rulers
demarcated in different units formed a glowing three-quarters frame
around the green circle.  It now measured 450 kilometers in diameter.

"Radiation levels are increasing rapidly," said Lianne.

"Thor, double our retreat speed," Keith said.  "Can our force screens
handle this?"

Lianne was consulting a set of readouts.  She shook her head.  "Not if
it gets much bigger."

The warbling sound was continuing in the background.

"Turn that damned alarm off," Keith said.  He looked at the Waldahud.

"Jag?"

"It's flat," Jag said.  "Like a wall of flame.  Diameter is now over a
thousand kilometers.  Thirteen hundred .  . . Seventeen hundred .  .  ."

The emerald light dominated the sky.  The humans brought up hands to
shield their eyes again.

Suddenly, a streamer of green fire shot out of the wall, like a neon
whiplash against the night.  It continued to stretch out until it had
extended over fifty thousand kilometers from the shortcut.

"My God .  . ."  said Rissa.

"Tell me that's not a weapon," said Jag, rising to his feet, and
standing with both sets of arms crossed behind his back.

"We would have been incinerated if we hadn't moved the ship."

"Could it--could it be the Slammers?"  asked Lianne.

The green streamer was now falling.  back toward the vast luminescent
circle of the shortcut.  As it did so, it broke up into fiery segments,
each thousands of kilometers long.

"Thor, prepare to go into hyperdrive on my order," Keith said.

"All stations, secure for hyperdrive," said Lianne's voice over the
loudspeakers.

"Is it a forcefield of some kind?"  asked Rissa.

"Unlikely," said Jag.

"If that is a ship's exhaust," Keith said, "it must have the biggest
goddamn ramscoop in history attached to the other end."

"Diameter is eight thousand kilometers," said Jag.  He had already
recalibrated the units on the scale bars twice.  ''Ten thousand .  .  ."

"Thor, thirty seconds to hyperdrive!"

"All stations, alert," said Lianne.  "Hyperdrive in twenty-five seconds,
mark."

Another tongue of green flame shot out of the widening circle.

"Hyperdrive in fifteen seconds, mark," said Lianne.

"Sweet Jesus, it's huge," Rissa said, under' her breath.

"Hyperdrive in five sec--hyperdrive initialization canceled!

Automatic override!"

"What?  Why?"  Keith looked at the pair of computer eyes mounted on his
workstation.  "PHANTOM, what's happening?"

"Gravity well is too steep for safe hyperspatial insertion," replied
the computer.

"Gravity well?  We're in open space!"

time."  He moved out from behind his console and jogged in front of the
cluster of workstations.  "Reduce display brightness by half."

Rhombus's ropes flicked.  The view of the giant green circle dimmed, but
it was still flaring, overexposed.

"Halve it again," snapped Jag.

The view grew dimmer.  Jag was trying to look at it, but it was still
too bright for eyes that had evolved under a dim red sun.  "Once more,"
he said.

The view darkened further--and suddenly there was detail visible on the
green surface: a granularity of lighter and darker shades .  . .

"That's not a ship," said Jag, his own voice, audible beneath PHANTOM's
translation, the staccato barking of Waldahud astonishment.  "It's a
star."

"A green starT' said Rissa, amazed.  "There's no such thing."

"Thor," Keith snapped, "full thruster power--perpendicular course away
from the shortcut.  Move!"

The alarm began to warble again.  "Level-two radiation warning!"

shouted Lianne overtop of it.

"Force screens to maximum," Keith snapped.

"Can't do both, boss," shouted Thor.  "Full thrusters can't be combined
with maximum screens."

"Priority to thrusters, then!  Get us out of here!"

"If that's a star," said Rissa, "we're way too close, aren't we?"  She
looked at Jag, who said nothing.  "Aren't we?"  she asked again.

Jag lifted his upper shoulders.  "Way, way too close," he said softly.

"If the radiation doesn't fry us," said Rissa, "the heat will."

"Thor, can't you get any more speed?"  Keith said.

"No can do, boss.  The local gravity well is steepening rapidly."

"Would we do better to abandon the mothership?"  asked Lianne.

"Perhaps our smaller ships could escape more easily?

"Forgive me, but no," said Rhombus.  "Beside the fact that we don't have
enough auxiliary vessels to evacuate everyone, only a few of them are
outfitted with shielding for close approaches to stars."

Lianne had her head tilted to one side; listening to private
communications over her ear implant.  "Director, we have panicked
messages coming in from all over the ship."

"Standard radiation precautions," snapped Keith.

"Those will be inadequate," said Jag softly as he moved back to his
workstation.

Keith looked over at Rissa.  One of her monitors was displaying plans
for Starplex, showing the two mutually perpendicular diamonds
intersecting the wide central disk.

"What happens," she said, turning to him, "if we rotate Starplex so that
the ocean deck is at a right angle to our line of travel?"

"What difference will that make?"  asked Keith.

"We could use the seawater as radiation shielding.  The ocean is filled
to a depth of twenty-five meters.  That's a lot of insulation."

Lights on Rhombus's web winked on and off.  "It would certainly
help--everyone who isn't on or below the ocean deck, that is."

Lianne spoke up.  "We'll all be fried unless we do something."

Keith nodded.  "Thor, rotate Starplex as described."

"ACS jets firing."

"Lianne, devise a plan to evacuate all personnel from decks thirty-one
through seventy."

She nodded.

"PHANTOM, intercom now!"

"Intercom on," said PHANTOM.

"Everyone--quickly.  This is Director Lansing.  Following instructions
from Internal-Ops Manager Karendaughter, evacuate decks thirty-one
through seventy.  Get out of the engineering torus, out of the docking
bays, out of the cargo holds, and out of all four lower-habitat modules.

Everyone move into the upper-habitat modules.  All dolphins--either get
out of the ocean deck altogether, or swim up to the surface of the ocean
and stay there.  Everyone,.  move in an orderly fashion--but move!

PHANTOM, end, translate, and loop."

In the hole display, the surface of the star was bulging out of the
circular shortcut opening.  "The shortcut-aperture expansion rate is
increasing rapidly," said Jag.  "It seemed to take a while to get going,
probably because the star was essentially flat at first, but now that
the surface is showing curvature, the thing is opening more quickly.

Diameter is now one hundred and ten thousand kilometers."

"Radiation is increasing rapidly as more of the surface comes through,"
said Lianne..  "And if it shoots another prominence in our direction,
we'll be cinderized."

"Evacuation status," snapped Keith.

Lianne pushed buttons and twenty-four square images appeared, replacing
part of the starscape bubble.  Each showed a different view through
PHANTOM's eyes, and the scenes kept shifting, cycling through the
computer's various cameras.

A corridor--level fifty-eight, according to the superimposed status
line: six Ibs rapidly rolling forward.

An intersection: three human women in track suits hurrying toward the
camera from one direction, and two Waldahudin and a human male rushing
in from the other direction.

The zero-g part of the central shaft: people using the handholds to
shoot themselves upward.

A vertical water tube, with three dolphins swimming up it.

An elevator car, with a Waldahud holding the door open with one arm and
urging passengers in with the other three.

Another elevator car, containing an Ib surrounded by a dozen humans.

"Even with everyone above the ocean deck," said Lianne, "I don't think
we're going to have enough radiation-shielding."

"Wait!"  said Thor.  "What about going behind the shortcut?"

"Eh?"  said Rhombus--or, at least, that's the sound PHANTOM gave to the
little ripple of lights that passed over his mantle.

"The shortcut's a circular hole," said Thor, looking over his shoulder
at Keith.  "The star is emerging from it.  The rear part of the shortcut
is a flat, empty circle--a black void in the shape of whatever's passing
through it.  If we're behind the shortcut, we'll be protected--at least
for a while."

Jag slapped all four of his hands against his console.

"He's right!"

Keith nodded.  "Do it, Thor.  Alter course to put us in the lee of the
shortcut, keeping the bottom of the ocean deck facing the emerging
star."

"Executing," said Thor.  "But it'll take a while to get there."  In the
spherical holo display encompassing the bridge, the brilliant circular
profile of the star slowly became a green dome as Thor maneuvered the
ship.

"Talldorsal to Lansing!"  A high-pitched dolphin voice over the
intercom, with splashing in the background.

"Open.  Lansing here."

"Thor's not moving in a line straight the ship.  We're getting tides on
the ocean deck."

"Lianne?"  Keith said, and the twenty-four views of the evacuation all
changed to different angles on the ocean.

Seawater was sloshing up to the holographic ceiling on the port side,
real waves touching fake clouds, forcing all the dolphins to the
starboard so that they could breathe.

"Damn," said Thor.  "Hadn't thought about that.  I'll rotate the ship
around its axis as we move.  With luck, I should be able to keep all the
forces balanced.  Sorry!"

As Starplex continued to move, the bulging dome of the green star became
progressively eclipsed by the featureless black circular backside of the
shortcut.  And then, at last, the green disappeared; Starplex was in the
shortcut's lee.  The only evidence for the emerging star was the emerald
cast on the dark-matter field beyond it.  Even the ring of Soderstrom
radiation was invisible back here; it, after all, was caused by tachyons
spilling out of the shortcut, heading in the opposite direction.  The
black circle continued to grow, though, blotting out more and more
background stars.  Its diameter was now 800,000 kilometers.

"Can you extrapolate how big the star is going to get, based on the
curvature we observed on the other side?" Keith asked Jag.

"It's not yet halfway through," Jag replied, "and it's oblate from
high-speed rotation.  Best guess?  One-point-five mil]ion kilometers."

"Thor, any chance of the hyperdrive?"  Keith asked.

Thor spoke into the hologram of Keith floating above his console rim.

"Not yet.  We'd have to be at least seventy million klicks from the
star's center before space would be flat enough to engage it.  I
estimate we'll reach that distance in eleven hours."

"Hours. How long till the star's equator passes through the shortcut?"

"Perhaps five minutes," said Jag.

"Evacuation status?"

"One hundred and ninety people are still below the ocean deck," said
Lianne.

"Will we make it?"  Keith asked her.

"I'm not--"

"Red light on thruster number six," shouted Thor.  "It's overheating."

"Great," Keith said.  "Do you need to take it off-line?"

"Not yet," said Thor.  "I'm injecting repair nanotechs into its
intercoolers; they may be able to correct the problem."

"The green star's equator is about to pass through the shortcut," said
Jag.

A portion of the holographic display changed to a schematic
representation of what was happening.  At the left was the bulging
hemisphere of the part of the star that had already protruded from the
shortcut.  The shortcut itself was seen from the side as a vertical
line.  Behind that, and receding away from it, was the diamond-shaped
profile of Starplex.  As the equator passed out of the shortcut, the
hole the shortcut made in space started shrinking, and photons and
charged particles from the star began spilling backward.  The edges of
the radiation backwash were like the hands of a clock starting at noon
and six and converging toward three o'clock.

Thor pushed Starplex as hard as he could.  Keith could see
constellations of yellow warning indicators lighting up on the pilot's
panel..  The ship continued to climb out of the star's gravity well, its
escape tunnel narrowing as the shortcut shrank in size.

"Lansing!"  shouted Jag.  "The dark-matter field is moving--moving away
from the star."

"Could it be because of that repulsive force you mentioned?"

Jag moved both sets of shoulders.  "It's not the kind of effect I'd
predict, but--"

"Lower-deck evacuation now complete," said Lianne, swinging around to
face the director.

"Even so," said Thor, "we're going to take one hell of a lot radiation
kick when that backwash hits us."

Finally, the star finished emerging, and the shortcut disappeared.  At
that point, Thor switched all power from the engines to the force
screens, trying to deflect as much of the incoming radiation as
possible.  Starplex continued to travel under momentum.  The radiation
alarm began to warble again.

"Are we far enough away?"  Keith asked.  Thor was too busy with the
controls to answer.  "Are we far enough away?"  he asked again.

Jag did some calculations.  "I think so," he said, "but only because
we're using the ocean deck as shielding.  Otherwise, we would all have
taken a lethal dose."

"All right," Keith said.  "Let's continue on until we're at a safe
distance.  Lianne, draw up a new duty roster that makes minimal use of
cetaceans, and put any nonessential dolphins into medical hibernation
until we can replace the water on the ocean deck.  At the rate the star
is receding from the shortcut, it'll be days before we can approach the
portal safely."  He paused, then: "Good work, everyone.  Rhombus, what's
the status of our docking bays?"

"They should still be usable.  Their walls are heavily shielded against
radiation leakage, in case a ship crashes or explodes in them."

"Good," said Keith.  "Thor, let me know when we're an acceptable
distance from that star."  He turned to the Waldahud.  "Jag, you should
go have a close look at it.  I want to know exactly where it came from
and why it's here."

Chapter VIII

It had taken a long time for humans to decipher dolphin speech.  When
they finally did so, delphinese names turned out to be sonargrams of
individual dolphins, with their most unusual physical characteristics
exaggerated.  It was no surprise, then, that the only form of human art
dolphins really enjoyed was political cartooning.

One of Starplexs' best probeship pilots was a dolphin whose English name
was Longbottle--a poor substitute for the song of trills and clicks that
painted a caricature of him for his kinfolk, emphasizing his mighty
snout.

Longbottle's favorite probeship was the Rum Runner, a bronze wedge
twenty meters long and ten wide.  A water tank ran down the ship's axis.

To the left and right were separate air-filled habitats that joined at
the rear in a U-shape with an airlock between them.  The port side was
normally kept to human standards; the starboard was set to cooler
Waldahud conditions.

To pilot the vessel, Longbottle let small free-floating sensor drones
clamp onto his flukes and pectoral fins.  The ship had hundreds of
attitude-control jets that allowed it to move in direct approximation of
the dolphin's own movements in his tank.  Such a technique was
extraordinarily wasteful of fuel--so much so that the Waldahudin had
refused to bid on the contract to build these vessels--but it provided
incredible maneuverability and, according to Long-bottle, was an
absolute joy to fly.

Although the Rum Runner could operate away from Starplex for weeks at a
time, on this mission it would be gone for less than a day, and the crew
would consist of just Longbottle and Jag.

The Rum Runner was normally stored in docking bay seven, one of five
that had locks leading through the engineering torus to the ocean deck.

The ship was clamped to the.deck's wall, and three access tubes at
shallow angles entered its rooftop hatches.

Once Longbottle and Jag were aboard, the segmented docking-bay door
moved up into the roofi Longbottle was famous for his theatrical
launches.  He zoomed the ship out of the bay, then rolled and arched in
his tank, taking the Rum Runner on a breathtaking warm-up flight past
all the docking-bay doors, swinging in a great circle around the central
disk.

He then rolled to one side in his tank, and the ship made a wide
arc--looking for all the world as though it were banking in the vacuum
of space.

Jag was getting impatient, but Longbottle, like all dolphins, was
oblivious to that.  He did a series of turns and flips in his tank, and
the ship responded in kind.  The gravity plates under Jag's compartment
compensated completely for the movements, but in his water-filled tube,
Longbottle could feel the ship as if it were an extension of his own
body.

Finally, when he'd had enough fun, Longbottle set off on a wildly
curving path--again, wasteful of energy, but so much more interesting
than the straight lines and precise arcs of normal celestial mechanics.

The green star dominated the sky, even though its surface was now thirty
million kilometers distant.  The Rum Runner had much better force
screens and physical shielding than did Starplex itself; it could make a
very close passage.

Under Longbottle's fanciful guidance, the ship dived in, skimming the
vast orb from just 100,000 kilometers above its photosphere.  Scoops on
the ship's leading edge sucked in samples of stellar atmosphere.

"Greenness of this star a baffiement to me," said Long-bottle, through
the hydrophone in his tank.  Like most dolphins, Longbottle could
approximate the sounds of both English and Waldahudar (although with
mangled syntax--there was no such thing as appropriate word order in
cetacean grammar).  The computer simply processed those sounds to make
them intelligible; it would only switch over to translation mode if a
dolphin was actually speaking in delphinese.

Jag grunted.  "I'm puzzled, too.  Its surface temperature is twelve
thousand degrees.  The fardint thing should be blue or white, not green.

The spectral analysis doesn't make 'any sense either.  I've never seen
such high concentrations of heavy elements in a star."

"Damaged perhaps by passage through shortcut?"  asked Longbottle,
twisting in his tank so that the ship would roll slowly around its axis.

Even with extra shielding, it wasn't safe to keep the same side facing
the star.

Jag grunted again.  "I suppose that's possible.  Most of the star's
chromosphere and corona were probably scraped off during passage through
the shortcut.  The shortcut's lips clamped down on the photosphere,
stripping away the rarefied gas above.  Still, all previous tests have
shown zero structural change in objects passing through a shortcut.  Of
course, nothing this big has ever gone through one before."

The Rum Runner's viewscreens were filled to the edges with flaming
green; the physical windows had all turned opaque.  "Take us in once
around the star's equator," said Jag, "then do a polar loop.  It's
possible that the star's structure isn't uniform.  Before I get too
worked up over these absorption lines, I want to be sure the spectra are
the same all over."

It took almost five hours at one one-thousandth of lightspeed to
complete the five-million-kilometer sweep around the equator, and
another five to do the loop from pole to pole.  Longbottle kept the Rum
Runner corkscrewing all the while.  Jag's eyes were glued to his
scanning equipment, watching the dark vertical absorption lines.  He
kept muttering to himself, "Silt in the water, silt in the water"--the
truth remained hidden.

Jag had no trouble measuring the star's mass from its footprint in
hyperspace; it was somewhat heavier than he'd expected.  Except for the
color, the star's surface was fairly typical, consisting of tightly
packed beads of light and dark caused by convection cells in the
photosphere.  It even had sunspots, but unlike those of other stars,
these were'all connected in dumbbell shapes.  It was, without doubt, a
star--but it was also unlike any star Jag had ever seen before.

Finally, the flybys were complete.  "Ready home to go?"

asked Longbottle.

Jag lifted all four arms in a gesture of resignation.  "Yes."

"Mystery solved?"

"No.  A star like this should simply not exist."

The Rum Runner swept back toward Starplex, Jag muttering over his data
for the entire journey.

Keith lay in bed next to his wife, unable to sleep.  He looked over at
Rissa's form in the darkness, watched the thin sheet covering her rise
and fall in time with her breathing.

She deserved better, he thought.  He exhaled, trying to force the
worries out of himself with the escaping breath, and conjured up images
of happier times.

Rissa had dark eyes that turned into upward-arching crescents when she
smiled.  Her mouth was small, but her lips were full--half as tall as
they were wide.  Her mother had been Italian; her father, Spanish.  She
had inherited her lustrous dark hair and his fiery eyes.  In his
forty-six years of life, Keith Lansing had never met anyone who looked
more appealing by candlelight than Rissa.

When they'd first met, in 2070, he'd been twenty-two and she'd been
twenty, with a wonderfully curvy figure.  Of course, her body shape was
changing in natural ways as she aged; she was still in fine condition,
but the proportions had shifted.  Back then, Keith couldn't have
imagined finding a woman of forty-four attractive, but to his infinite
surprise, his tastes had altered as the years passed, and although two
decades of marriage had doubtless dulled his immediate reaction to her,
when he saw Rissa in an unusual way--in a new suit, or stretching to
reach something on a top shelf, or with her hair swept in a different
manner--she could still take his breath away.

And yet .  . .

And yet, Keith was aware that time was taking its toll on him.  His hair
was departing.  Oh, there were "cures" for that--imagine suggesting that
something as natural as male-pattern baldness required a cure!--but to
employ them seemed vain and foolish.  Besides, middle-aged scientists
were supposed to be bald.  It was in the rule book somewhere.

Keith's father had had a full head of dark hair up until he'd been
killed at age fifty-five; Keith wondered now whether he'd used a hair
restorer.  But for Keith to do something like that would be silly.

He remembered Mandy Lee, a holovid star he'd been infatuated with as a
twelve-year-old boy.  Back then, nothing had been more exciting to him
than large breasts on a woman, probably because none of the girls in his
class yet had them; they were a symbol of the forbidden, alien world of
adult sexuality.  Well, Mandy--dubbed "the binary star system" by some
wag at HV Guide--was famous for her physique.  But Keith had lost all
interest in her when he'd found out that her breasts were fake; he
couldn't look at her without imagining the implants beneath the swelling
alabaster skin and the surgical scars (even though he knew, of course,
the anabolizing laser scalpels would have left no marks at all).  Well,
he'd be damned if he'd turn his head into a fake; he'd be damned if he'd
let people looking at him think, hey, the guy's really bald, you know .

. .

And so there they were, Rissa Cervantes and Keith

Lansing: still in love, if not in the passionate way of their youth, in
what was ultimately a more satisfying, more relaxing fashion.

And yet-- And yet, dammit, he'd just turned forty-six.  He was aging,
balding, graying, and hadn't been with another woman since his
three--such a small number!--awkward encounters in high school and at
university.  Three, plus Rissa--a total of four.  An average of less
than one a decade.

Christ, he thought, even a Waldahud could count my partners on the
fingers of one hand.

Keith knew he shouldn't think about such things, knew that what he and
Clarissa had was something most people never really achieved: a love
affair that grew and evolved as they aged, a relationship that was solid
and secure and warIll.

And yet-- And yet there was Lianne Karendaughter.  Like Mandy Lee, the
very symbol of beauty in his youth, Lianne had exquisite Asian features;
something about Asian women had always appealed to Keith.  He didn't
know how old Lianne was, but there was no doubt that she was younger
than Rissa.  Of course, as ship's director, Keith could easily access
Lianne's personnel records, but he was afraid to do so.  For God's sake,
she might be as young as thirty.  Lianne had come aboard the last time
Starplex had passed by Tau Ceti, and now, as Internal Operations
manager, she and Keith often spent hours together on the bridge.  And
yet, to his surprise, no matter how much time he spent with her, he
always wished it were more.

He hadn't done anything foolish yet.  Indeed, he thought he had
everything under control.  Still, he'd always been an introspective
sort; he wasn't blind to what was going on.

Midlife crisis, the fear that he was no longer virile.  And what better
way to dispel that notion than by bedding a beautiful, young woman?

Idle fantasies.  Of course, of course.

He rolled onto his side, facing away from Rissa, tucking himself into a
semifetal position.  He didn't want to do anything that would hurt
Rissa.  But if she never learned about it-- Christ, man, get a grip.

She'd find out for sure.  How would he face her after that?  And their
son Saul?  How would he face him?  He'd seen his son beam at him with
pride, yell at him in fury, but he'd never seen him look at him with
disgust.

If only he could get some sleep.  If only he could stop tormenting
himself.

He stared into the darkness, eyes wide open.

Once the Rum Runner had docked, Longbottle went off to eat, and Jag
returned to the bridge.  The Waldahud was now keeping erect by use of an
intricately carved cane--still better than reverting to four legs.

Keith, Rissa, Thor, and Lianne had all had a night's sleep, and
Rhombus--well, Ibs didn't sleep, a fact that made their long lifespans
seem doubly unfair.  Jag usually stood in front of the six workstations
to give reports, but this time he walked back to the seating gallery and
collapsed into the center chair, letting the others rotate their
stations to face him.

Keith looked at the Waldahud expectantly.  "Well?"

Jag marshaled his thoughts a moment, then began to bark.

"As some of you know, stars are divided into three broad age categories.

First-generation stars are the oldest in the universe, and consist
almost entirely of hydrogen and helium, the two original elements.

Less than 0.02 percent of their composition is heavier atoms, and those,
of course, were produced internally through the stars' own fusion
processes.  When first-gens go nova or supernova, the interstellar dust
clouds are enriched with these heavier elements.

Since second-generation stars coalesced from such clouds, a full percent
or a bit more of a second-gen's mass comes from metals--'metals' in this
context meaning elements heavier than helium.

Third-generation stars are even more recent; the suns of all the
Commonwealth homeworlds are third-gens, as are all stars being born
today, although, of course, some first-gens and a lot of second- gens
are still around, too.  Third-gens consist of about two percent metals."

Jag paused for a moment, and looked from face to face in the room.

"Well," he said, "that star"--he gestured with one of his medial arms at
the green orb in the holo sphere--"has about eight percent of its mass
as metals, four times as much as even a typical third-gen.  The thing
has enough iron in it that you could actually mine it."

"What about the green color?"  asked Keith.

"It's not really green, of course, any more than a so-called red star is
actually red.  Almost all stars are white, with just a hint of color."

He gestured with his medial limbs at the starfield around them.

"PHANTOM routinely colorizes the stars in our holo bubble, assigning
them colors based On their Hertzsprung-Russell categories.

The star out there just has a greenish tinge.  The absorption-line
blanketing due to its metal content is stronger than the backwarming,
and that weakens the star's output in the blue and ultraviolet.  The
result is more of the star's light coming out in the green region of the
spectrum."  His fur danced.  "I would have said a star with so much
metal content would be impossible in our universe at its present age if
I hadn't seen one with my own four eyes.  It must have formed under very
peculiar local conditions, and--"

"Forgive the interruption, good Jag," said Rhombus, "but I'm detecting a
tachyon pulse."

Keith swiveled in his chair, facing the shortcut.

"Gods," said Jag, rising to his feet.  "Most stars are part of multiple
star systems--"

"We can't take another close passage," said Lianne.

"We'll--"

But the shortcut had already stopped expanding.  A small object had
popped through.  The gateway had grown to only seventy centimeters in
diameter before collapsing down to an invisible point.

"It's a watson," announced Rhombus.  An automated communications buoy.

"Its transponder says it's from Grand Central Station."

"Trigger playback," Keith said.

"The message is in Russian," said Rhombus.

"PHANTOM, translate."

The central computer's voice filled the room.  "Valentina Ilianov,
Provost, New Beijing Colony, to Keith Lansing, commander, Starplex.  An
M-class red-dwarf star has erupted from the Tau Ceil shortcut.

Fortunately, it emerged heading away from Tau Ceil, rather than toward
it.  So far, no real damage has been done, although we had trouble
piloting this watson past the star and into the portal.  This is our
third attempt to reach you.  We did manage to contact the astrophysics
center on Rehbollo for advice, and they had the incredible news that a
star has popped out of the shortcut near them as well--a blue B-class
star, in their case.  I am now contacting all other active shortcuts to
find out just how widespread this phenomenon is.  End of message."

Keith looked around the bridge, bathed in green starlight.

"Christ Jesus," he said.

Chapter IX

"I say we're under attack," announced Thoraid Magnor, getting up from
the helm position, and walking over to the seating gallery to sit a few
chairs to the right of Jag.  "We've apparently been lucky so far, but
dropping a star into a system could destroy all life there."

Jag moved his lower two arms in a Waldahud gesture of negation.  "Most
shortcuts are in interstellar space," he said.

"Even the one you call "the Tau Ceti shortcut' is still thirty-seven
billion kilometers from that star, more than six times as far as Pluto
is from Sol.  I would say that in fifteen out of sixteen cases, the
arrival of additional stars would have minor effects on the closest
systems, and, since inhabited worlds are few and far between, the
chances of actually doing short-term damage to a planet with life on it
are quite small."

"But could these stars be, well, bombs?"  asked Lianne.

"You said that the green star is very unusual.  Could it be about to
explode?"

"My studies of it have only begun," said Jag, "but !  would say that our
new arrival has at least a two billion years of life left.  And
singleton M-class dwarfs, like the one that popped out near Tan Ceti,
don't go nova."

"Still," said Rissa, "couldn't they disturb the Oort clouds of star
systems they pass close to, sending showers of comets in toward the
inner planets?  I remember an old theory that a brown dwarf
dubbed--Nemesis, I think it was--might have passed close to Sol, causing
an onslaught of comets at the end of the Cretaceous."

"Well, Nemesis turned out not to exist," said Jag, "but even if it did,
today each of the Commonwealth races has the technology to deal with any
reasonable number of cometary bodies--which, after all, would take
decades or even centuries to fall into the inner part of a system.  It
is not an immediate concern."

"But why, then?"  asked Thor.  "Why are stars being moved around?  And
should we try to stop it?"

"Stop it?"  Keith laughed.  "How?"

"By destroying the shortcuts," said Thor, simply.

Keith blinked.  "I'm not sure they can be destroyed," he said.

The Waldahud's fur danced pensively for a moment, and when he spoke, his
bark was subdued.  "Yes, theoretically, there is a way."  He looked up,
but neither of his eye pairs met Keith's gaze.  "When first contact with
humans was not going well, our astrophysicists were charged with finding
a way to close the Tau Ceti shortcut, if need be."

"That's outrageous!"  said Lianne.

Jag looked at the human.  "No, that is good government.

One must prepare for contingencies."

"But to destroy our shortcut!"  said Lianne, anger bringing unfamiliar
lines to her face.

"We did not do dit," said Jag.

"To contemplate it, though!  If you didn't want us to have access to
Rehbollo, you should have destroyed your own shortcut, not ours."

Keith turned around to look at the young woman.

"Lianne," he said softly.  She faced him, and he mouthed the words "cool
it" at her.  He turned back to Jag.  "Did you find a way to do it?  To
destroy a shortcut?"

Jag lifted his upper shoulders in assent.  "Gaf Kandaro em-Weel, my
sire, was head of the project.  The shortcuts are hyperspatial
constructs that extrude a nexus point into normal space.  An absolute
coordinate system exists in hyperspace.  That's why Einsteinian speed
restrictions don't apply there; it is not a relativistic medium.  But
normal space is relativistic, and the exit--the thing we call the
shortcut portal--has to be anchored relative to something in normal
space.  If one could disorient the anchor point, so that it no longer
could extrude through from hyperspace, the point should evaporate in a
puff of Cerenkov radiation."

"And how would you disorient the anchor?"  Keith asked, his tone
betraying his skepticism.

"Well, the key is that the shortcut is indeed a point, until it swells
up to accommodate something passing through it.

A spherical array of artificial-gravity generators assembled around the
dormant shortcut could be designed to compensate for the local curvature
of spacetime.  Even though most shortcuts are in interstellar space,
they are still within the dent made by our galaxy.  But if you remove
that dent, the anchor would have nothing to hold on to, and--poof!--it
should disappear.  Since the shortcut is so small when dormant, an array
only a meter or two across should be able to do the trick, so long as it
is fed enough power."

"Could Starplex provide the power required?"  asked Rhombus.

"Easily."

"That's incredible," Keith said.

"It isn't, really," said Jag.  "Gravity is the force that dents
spacetime; artificial gravity is all about modifying those dents.  In my
home system, we have used gravitation buoys in emergency situations to
flatten spacetime locally so that hyperdrives could be engaged while
still close to our sun."

"How come none of this has ever appeared on the Commonwealth
Astrophysics Network?"  asked Lianne, her tone sharp.

"Um, because no one ever asked us?"  said Jag weakly.

"Why didn't you suggest we do that, then, to enable us to go to
hyperdrive when the Teen star first appeared?"

demanded Keith.

"You can't do it to yourself; it has to be done to you, by an external
power source.  Believe me, we've tried to develop ways for ships to do
it on their own, but it doesn't work.  To use the human metaphor, it
would be like trying to pull yourself up by your own bootstraps.  It
can't be done."

"But if we were to do this right here and now--cause this shortcut to
evaporate--we wouldn't be able to get back home," Keith said.

"True," said Jag.  "But we could set up the antigrav buoys to converge
on the shortcut after we had gone through it."

"But stars are apparently popping out of lots of shortcuts," said Rissa.

"If we were to evaporate the Tau Ceti and Rehbollo and Flatland
shortcuts, we'd be destroying the Commonwealth, cutting each of our
worlds off from the other."

"To protect the individual worlds of the Commonwealth, yes," said Thor.

"Christ," said Keith.  "Surely we don't want to end the Commonwealth."

"There is one other possibility," said Thor.

"Oh?"

"Transplant the COmmonwealth races to adjacent star systems far distant
from any shortcut.  We could find three or four systems close together,
with the right sorts of worlds, terraform them into habitable
conditions, and move everyone there.  We would still be able to have an
interstellar community via normal-hyperdrive."

Keith's eyes were wide.  "You're talking about moving-- what?--thirty
billion individuals?"

"Give or take," said Thor.

"The Ibs will not leave Flatland," said Rhombus, with uncharacteristic
bluntness.

"This is crazy," Keith said.  "We can't shut down the shortcuts."

"If our homeworlds are in jeopardy," said Thor, "we can--and we should."

"There's no proof that the arriving stars represent any threat," Keith
said.  "I can't believe that beings advanced enough to move stars around
are malevolent."

"They may not be," said Thor, "any more than construction workers who
destroy anthills are malevolent.  We might simply be in their way."

There was nothing Keith could do about the arriving stars until more
information was available, and so, at 1200 hours, he and Rissa went off
to find something to eat.

There were eight restaurants aboard Starplex.  The terminology was
deliberate.  Humans kept wanting to refer to Starplex's components in
naval terms: mess halls, sickbays, and quarters, instead of restaurants,
hospitals, and apartments.

But of the four Commonwealth species, only humans and Waldahudin had
martial traditions, and the other two races were nervous enough about
that without being reminded of it in casual conversation.

Each of the restaurants was unique, both in ambience and fare.

Starplex's designers had taken great pains to make sure that shipboard
life was not monotonous.  Keith and Rissa decided to have lunch in Keg
Tahn, the Waldahud restaurant on deck twenty-six.  Through the
restaurant's fake windows, holograms of Rehbollo's surface were visible:
wide, flat flood plains of purple-gray mud, crisscrossed by rivers and
streams.  Clumps of stargin were scattered about--Rehbollo's counterpart
of trees, looking like three- or four-meter-tall blue tumbleweeds.  The
moist mud didn't offer any firm pumhase, but it was rich with dissolved
minerals and decaying organic material.  Each starg had thousands of
tangled shoots that could serve either as roots, or, unfurling
themselves, as photosynthesis organs, depending on whether they ended up
on top or on the bottom.  The giant plants blew across the plains,
rotating end over end, or floated down the streams, until they found
fertile mud.

When they did so, they settled in, sinking until about a third of their
height was embedded in the ooze.

The holographic sky was greenish gray, and the star overhead was fat and
red.  Keith found the color scheme dreary, but there was no denying that
the food here was excellent.  Waldahudin were mainly vegetarians, and
the plants they enjoyed were succulent and delicious.  Keith found
himself craving starg shoots three or four times a month.

Of course, all eight restaurants were open to every species, and that
meant offering a range of meal items that met the various races'
metabolic requirements.  Keith ordered a grilled cheese sandwich and a
couple of pickled gherkins to go with his starg salad.  Waldahudin,
whose females, like terrestrial mammals, secreted a nutritive liquid for
their offspring, found it disgusting that humans drank the milk of other
animals, but they pretended not to know what cheese was made of.

Rissa was sitting opposite Keith.  Actually, the table was shaped in the
Waldahud standard, like a human kidneY, and made of a polished plant
material that wasn't wood, but did have lovely bands of light and dark
in it.  Rissa was in the indentation in the table.  The Waldahud custom
was that a female always sat in this honored position; on their
home-world a dame would be positioned here, with her male entourage
seated around the curving form.

Rissa's tastes were more adventurous than Keith's.  She was eating az
torad--"blood mussels," Waldahud bivalves that lived in the slurry layer
at the bottom of many lakes.  Keith found the bright purple-red color
disgusting as did most Waldahudin, for that matter, since it was a
precise match for the hue of their own blood.  But Rissa had mastered
the trick of bringing the shell to her mouth, popping it open, and
slurping out the morsel within, all without letting the soft mass be
seen either by herself or anyone sitting across from her.

Keith and Rissa ate in silence, and Keith wondered if that was good or
bad.  They'd mn out of idle chitchat ages ago.  Oh, if there was
something on either of their minds, they'd talk at length, but it seemed
that they just enjoyed being in each other's company, even if they said
barely a word.  At least that's the way Keith felt, and he hoped Rissa
shared that feeling.

Keith was using a katook (Waldahud cutlery, like duck-billed pliers) to
bring some starg to his mouth when a comm panel popped up from the
table's surface, showing the face of Hek, the Waldahud
alien-communications specialist.

"Rissa," he barked in a voice somewhat more Brook-lynish than Jag's;
from the way the comm panel was angled, the Waldahud couldn't see Keith.

"I have been analyzing the radio noise we've been detecting near the
twenty-one-centimeter band.  You won't believe what I've found.  Come to
my office at once."

Keith put down his eating utensil, and looked across the table at his
wife.  "I'll join you," he said, and stood up to leave.  As they made
their way across the room, he realized it was the only thing he'd said
to her during the entire meal.

Keith and Rissa got into an elevator.  As always, a monitor on the cab's
wall showed the current deck number and floor plan: "26," and a cross
shape with long arms.  As they rode up, and the deck numbers counted
down, the arms of the cross grew shorter and shorter.  By the time they
reached deck one, the arms had almost completely retracted.

The two humans got out and entered the radio-astronomy listening room.

Hek, a small Waldahud with a hide much redder in color than Jag's, was
leaning against a desk.

"Rissa, your presence is welcome"--the standard deference shown females.

A tilt of the head: "Lansing."  The rude indifference reserved for
males, even if they were your boss.

"Hek," said Keith, nodding in greeting.

The Waldahud looked at Rissa.  "You know the radio noise we've been
picking up?"  His barking echoed in the tiny room.

Rissa nodded.

"Well, my initial analysis showed no repetition in it."  He swiveled a
pair of eyes to look at Keith.  "When a signal is a deliberate beacon,
it usually has a repeating pattern over a course of several minutes or
hours.  There's nothing like that at work here.  Indeed, I've found no
evidence of any overall pattern.  But when I started analyzing the noise
more minutely, patterns of one-second duration or less kept cropping up.

So far, I've cataloged six thousand and seventeen sequences.  Some have
only been repeated once or twice, but others have been repeated many
times.  Over ten thousand times, for a few of them."

"My God," said Rissa.

"What?"  said Keith.

She turned to him.  "It means that there might be information in the
noise--it might be radio communications."

Hek lifted his upper shoulders.  "Exactly.  Each of the patterns could
be a separate word.  Those that occur most frequently could be common
terms, maybe the equivalent of pronouns or prepositions."

"And where are these transmissions coming from?"  asked Keith.

"Somewhere in or just behind the dark-matter field," said Hek.

"And you're sure they're intelligent signals?"  asked Keith, his heart
pounding.

Hek's lower shoulders moved this time.  "No, I'm not sure.

For one thing, the transmissions are very weak.  They wouldn't be
discernible from background noise over any great distance.

But if I'm right that they're words, then there does appear to be some
discernible syntax.  No word is ever doubled.  Certain words only appear
at the beginning or end.  of transmissions.

Some words only appear after certain other words.  The former are
possibly adjectives and adverbs, and the latter the nouns or verbs they
are modifying, or vice versa."  Hek paused.  "Of course, I haven't
analyzed all the signals, although I am recording them for future study.

It's a constant bombardment, on over two hundred frequencies that are
very close to each other."  He paused, letting this sink in.

"i'd say there's a good possibility that there's a fleet of craft hiding
inside or just past the dark-matter field."

Keith was about to speak again when Hek's desk intercom bleeped.

"Keith, Lianne here."

"Open.  Yes?"

"I think you'll want to come to the bridge.  A watson has arrived with
word that the boomerang has returned from shortcut Rehbollo 376A."

"On my way.  Summon Jag, too, please.  Close."  He looked at Hek.

"Good work.  See if you can narrow down the source of the signals
further.  I'll have Thor take Starplex in a circular path around the
dark-matter field, scanning for tachyon emissions, radiation, thruster
glow, or any other signs of alien ships."

Keith strode onto the bridge, Rissa right behind him.  They moved to
their workstations.  "Trigger watson playback," said Keith.

Lianne pushed a button, and a full-motion video message appeared in a
framed-off section of the holographic bubble.

The image was of a Waldahud male with a silvery-gray hide.  PHANTOM
replaced the sound of the creature's barking with English words for the
playback into Keith's ear implant, although, of course, they didn't fit
the movements of the Waldahud's mouth.

"Greetings, Starplex."  The status line at- the bottom of the screen
identified the speaker as Kayd Pelendo em-Hooth of the Rehbollo Center
for Astrophysics.  "The boomerang sent to the shortcut designated
Rehbollo 376A has returned.  I suspect you'll want to stay where you
are, investigating the shortcut you're at now, since its appearance on
the network is unexplained.  However, we thought Jag and others would be
interested in seeing the recordings made by the boomerang just before
returning home.  They are appended to this message.  I think you will
find them .  . . interesting."

"Okay, Rhombus," said Keith.  "Use the data from the boomerang to create
a spherical holo display around us.

Show us what it saw."

"A pleasure to serve," said Rhombus.  "Downloading now; the display will
be ready in two minutes, forty seconds."

Lianne rubbed her hands together.  "It never rains but it pours," she
said, turning' around and grinning at Keith.  "Yet another new sector of
space opened up for exploration!"

Keith nodded.  "It never ceases to amaze me."  He got up from his chair,
and paced a little, waiting for the hologram to be prepared.

"You know," he said absently, "my great-great-grandfather kept a diary.

Just before he died, he wrote about all the great advancements he'd seen
in his lifetime:

radio, the automobile, powered flight, spaceflight, lasers, computers,
the discovery of DNA, and on and on."  Lianne seemed rapt, although
Keith was aware that he might be boring everyone else.  To hell with
them; rank hath its privileges, chief among them the right to ramble on.

"When I read that as a teenager, I figured I'd have nothing to write
about for my own descendant when my life came to a close.

But then we invented hyperdrive and AI, and discovered the shortcut
network, and extraterrestrial life, and learned to talk to dolphins, and
I realized that--"

"Excuse me," said Rhombus, his lights flashing in the strobing pattern
high species used to signal an interruption.

"the hologram is ready."

"Proceed," Keith said.

The bridge darkened as the image of Starplex's current surroundings was
shut off, shrouding the room in featureless black.  Then a new picture
built up from left to right, scan line by scan line, washing over the
bridge, until it seemed once again to be floating in space--the space of
the newest sector to become accessible to the Commonwealth races.

Thor let out a long, low whistle.

Jag clicked his dental plates in disbelief.

Dominating the view, receding slowly, was another fiery green star,
perhaps ten million kilometers from the shortcut point.

"I thought you said our green star was a freak," said Keith to Jag.

"That's the least of our worries," said Thor.  He swung his feet off his
console and turned to face Keith.  "Our boomerang didn't activate that
shortcut until it dived into it."

Keith looked at him blankly.

"And these pictures were taken before it did that."

Jag rose to his feet.  "Ka-darg.t That means--"

"It means," said Keith, suddenly getting it, too, "that stars can emerge
from dormant shortcuts.  Christ, they could be popping out of all four
billion portals throughout the Milky Way!"

Chapter X

That night, Keith was eating dinner alone.  He loved to cook, but he
also loved to have someone to cook for--and Rissa was working late this
evening.  She and Boxcar had finally had a breakthrough in their
Hayflick-limit studies, or, at least, so it appeared.  But they were
having trouble replicating the results, and so she'd just had sandwiches
sent up to her lab.

Keith sometimes wondered how he'd gotten the job as Starplex's head
honcho.  Oh, it made sense, of course.  A sociologist was assumed to be
good both at managing the miniature society aboard the ship and at
dealing with any new civilizations they might encounter.

But right now, despite all that was going on, there was little for him
to do beyond the administrative.  Jag would continue his dark-matter
studies, as well as trying to make sense of the onslaught of stars; Hek
would try to further decode the potentially alien radio signals; Rissa
would pursue her life-prolongation project.  And Keith?  Keith kept
hoping a windmill somewhere would start tilting at him--kept hoping for
something important to do.

He'd decided to dine in one of the Ib restaurants.  Not for-the
atmosphere, of course.  With its almost billiard-ball-smooth surface,
Flatland's landscapes, as depicted in the restaurant's holographic
windows, were even less visually interesting than Rehbollo's; there was
no doubt that when it came to interesting geography, Earth was the most
beautiful of the homeworlds.  But Ibese food was based on right-handed
ammo acids; it was completely indigestible by the other three races.

This restaurant, though, offered a wide range of human fare--including a
chicken stir-fry, which was exactly what Keith had been craving.

The restaurant was inordinately crowded; the four eating establishments
in the lower-habitat modules were still uninhabitable.  But one of the
other privileges of rank was always getting a table without a wait.  A
sleek, silver robot showed Keith to a booth in the back.  A large
gestalt plant arched over it, orange octagonal leaves roaming its body
freely.

Keith told the server what he wanted, and then he spoke to the desktop
viewer, asking for the latest issue of the New Yorker to be displayed.

The server returned with a glass of white wine, then rolled away.

Keith was settling into the lead fiction piece in the magazine
when-Bleep.  "Karendaughter to Lansing."

"Open.  Yes, Lianne?"

"I've finished the engineering study on what to do about the irradiated
lower decks.  Can we get together so that I can give you my report?"

Keith swalloed once.  Of course the report had to be dealt with right
away; they needed to solve the overcrowding problem quickly.  But where
to meet Lianne?  Gamma shift would be on the bridge now; no need to
disturb them.

Keith's office would be the natural place, but .  . . but .  . .

did he really trust himself to be alone with her?

Christ, this is stupid.  "I'm in the Drive-Through, having dinner.  Can
you bring the report here?"

"Sure thing.  On my way.  Close."

Keith had a sip of wine.  Maybe this was a mistake.

Maybe people would misconstrue, tell Rissa that he'd had a rendezvous in
a booth with Lianne.  Maybe-- Lianne came in, escorted to his table by a
robot.  She sat down opposite him and smiled.  Geez, she'd arrived
quickly--almost as if she'd known where he was before calling, almost as
if she'd planned to catch him alone at dinner .  . .

Keith shook his head.  Get real.  "Hi, Lianne," he said.

"You've got a report for me?"

"That's right."  She was dressed in a cyan suit, crisp and professional.

But on her head, crowing her lustrous platinum hair, she was wearing a
smart replica of an old-style railway engineer's cap.

Keith had seen her wearing it before, whimsical and stylish and sexy all
at once.  '"There are techniques," she said, "for cleaning up radiation
damage.

But they're all time-consuming, and--"

The server arrived, bringing Keith's dinner.

"Stir-fry," said Lianne, smiling.  "I make a mean one of those.  You
should let me do it for you sometime."

Keith reached for his wine, thought better of it, picked up his napkin,
and, in so doing, sent his fork tumbling onto the rubberized floor.  He
bent down to retrieve it--and saw Lianne's shapely legs beneath the
table.

"Um, thank you," he said, straightening back up.  "That'd be nice."

He indicated the steaming platter between them.

"Did you--did you want some?"

"Oh, no," she said, patting her flat stomach, causing the fabric of her
suit to pull tight across her breasts as she did so.  "I'll have a salad
later.  I've got to watch my figure."

No need for that, thought Keith.  I'll be glad to watch it for you.

"About the radiation?"  he said.

She nodded.  "Right.  Well, as I said, we can clean it up--but not
quickly, and not without putting into drydock for several weeks."

"Weeks!"  said Keith.  "We can't afford that kind of time."

"Exactly.  Which brings me to my suggested solution."

Keith waited for her to go on.  "Which is?"

"Starplex 2."

Keith frowned.  Starplex had been built at the Rehbollo orbital
shipyards, and its sister ship--currently carrying the.

prosaic name of Starplex 2, although something else would likely end up
being the official name--had been under construction now for close to a
year.  It was being built at Flatland; two such prime contracts couldn't
go to the same homeworld, naturally.  "What about her?"

"Well, she's not yet ready for launch, or I'd say simply commandeer the
whole thing.  But she's being built from identical blueprints to
Starplex /--and five of her eight habitat modules are already completed,
according to the last report I received.  We could pop through the
shortcut to the Flatland shipyards, dump our lower-four habitat modules
there, and replace them with four of the completed ones for Starplex 2.

The modules that we leave off could then be cleaned up at leisure.

Starplex 2's central disk won't be ready for another five months; the
four hyperdrive generators have to be extensively tested before the
engineering torus can be built around them.  That should give plenty of
time for the cleanup.  When the time comes, our four old modules could
be incorporated into the new ship.  Of course, all the individual
furnishings and equipment we had in our lower four will need to be
cleaned up, too, but at least we'll have quarters and lab space for
everyone right away."

Keith nodded, impressed.  "That's brilliant.  How long would that take?"

"The specs for habitat-module power-grid deconnection and reconnection
call for three days, but I've devised an improved method that doesn't
require powering down the couplings.  I could do it in fifteen hours if
we didn't need to wear radiation suits in the lower modules; in this
case, eighteen hours should do the trick."

"Excellent.  What about the lower part of our main shaft and our central
disk?"

"Well, the shaft is three quarters fixed up already.  We can't clean it
easily, but I've had nanotechs laying down extra shielding on its inner
surface.  As for the central disk, we'll have to completely replace the
water in the ocean deck, of course.  And not just with plain water,
either.  It has to be a full seawater formulation, with dissolved salt
and other minerals, plus, if possible, plankton and fish stocks.

Also, I'd like to replace all the shipboard air, just to be on the safe
side.  The docking bays are no problem--they're heavily shielded.  Same
thing for the engineering torus; its shielding kept it from getting too
much of a hit of radiation, as well."

Keith nodded.  "How long till we can safely maneuver through the
shortcut?"

"Tomorrow afternoon, maybe earlier.  The gap between the shortcut and
the green star is opening rapidly.  And as long as you're willing to
risk losing half a dozen watsons in trying, we should be able to get
word of our intentions through to the Flatland shipyards right away so
that the Ibs can start preparing for our arrival."

"Good work, Lianne."  He looked at her, and she smiled again, a
beautiful, warm, intelligent smile.  Keith mentally kicked himself for
sometimes forgetting that there was a reason she was aboard Starplex.

Lianne Karendaughter was the best starship engineer in the business.

Thor piloted Starplex through the shortcut, and it popped out at the
periphery of the Flatland system.  From here, the Magellanic Clouds
dominated the sky.  Flatland's sun, Hotspot, was a white F-class star,
and Flatland itself was a featureless ball, shrouded in white clouds.

Ibs were incapable of working in zero-g.  Keith watched from a window as
thousands of them swarmed around Starplex in hockey-puck-shaped solo
travel units, transparent except for the opaque artificial-gravity
plates that made up their bottoms.  Since the work was being done by
Ibs, not a second was being wasted.  The new habitat modules were locked
into place, giving Starplex all-new decks forty-one through seventy.

Keith could just make out the bubble-shaped travel pod from which Lianne
was orchestrating the entire operation.  The only problem during the
whole refit occurred when the hose draining off the ocean deck ruptured,
and salt water sprayed into space, freezing into tiny ice particles that
sparkled like diamonds in the white glare from Hotspot.

When it was all done, Starplex--now a hybrid of Starplexes and 2--headed
back through the shortcut.  '

Keith was delighted with the repairs--and even more delighted that
everyone would no longer have to crowd into the upper half of the ship.

Arguments had been breaking out among members of all the races.

Perhaps now that they had plenty of room again, peace .would once more
reign aboard Starplex.

While at the Rehbollo shipyards, five new researchers were brought
aboard--one Ib and two Waldahud dark-matter specialists, and a dolphin
and a human who were experts in stellar evolution.  All of them had
dropped everything at receipt of Starplex's reports, and immediately
headed through the shortcut network to rendezvous with the ship at
Flatland.

As she had promised, Lianne finished the refit in less than eighteen
hours.  Thor piloted the ship back through the shortcut, and they
teemerged in the vicinity of the dark-matter field and the enigmatic
green star.

Chapter XI

Starplex's designers had planned to put the director's office adjacent
to the bridge, but Keith had insisted that be changed.  The director, he
felt, should be seen all over his ship, not just in one isolated area.

He had ended up with a large square room, almost four meters on a side,
located on deck fourteen, halfway along one of the triangular faces of
habitat module two.  Through the window that covered one wall, he could
see module three, perpendicular to the one he was in, as well as a
ninety-degree slice of the copper-colored circular roof of Starplex's
central disk sixteen floors below.  That particular part of the roof was
marked with Starplex's name in wedge-shaped Waldahudar lettering.

Keith sat behind a long rectangular desk, made of real mahogany.  On it
were framed holos of his wife Rissa, looking exotic in an old-fashioned
Spanish dancing dress, and their son Saul, wearing a Harvard sweatshirt
and sporting that strange goatee that was the current fashion among
young men.  Next to the holos was a 1/600 scale mode!

of Starplex.  Behind his desk was a credenza with globes of Earth,
Rehbollo, and Flatland on it, as well as a traditional go board with
playing pieces of polished white shell and slate.

Above the credenza was a framed print of an Emily Cart painting,
depicting a Haida totem pole in a forest on one of the Queen Charlotte
Islands.  Flanking the credenza on either side were large potted plants.

A long couch, three polychairs, and a coffee table were also in the
room.

Keith had his shoes off, and had swung his feet up on his desk.  He
never emulated Thor while on the bridge, but when alone he often adopted
this posture.  He was leaning back in his black chair, reading a report
on the signals Hek had been detecting, when the door buzzer sounded.

"Jag Kandaro em-Pelsh is here," announced PHANTOM.

Keith sighed, sat up straight, and made a let-him-in motion with his
hand.  The door slid aside, and Jag walked in.  After a moment, the
Waldahud's nostrils started flaring, and Keith thought perhaps Jag could
smell his feet.  "What can I do for you, Jag?"

The Waldahud touched the back of one of the polychairs, which configured
itself to accommodate his frame.  He sat down and began to bark.  The
translated voice said, "Few of your Earth literary characters appeal to
me, but one who does is Sherlock Holmes."

Keith lifted an eyebrow.  Rude, arrogant--yes, he could see why Jag
might like the guy.

"In particular," continued Jag, "I like his ability to encapsulate
mental processes into maxims.  One of my favorite sayings of his is,
"The truth is the residue, lacking in likelihood though it may be, that
is left behind when those things that cannot be are omitted from
consideration.""

That, at least, brought a smile to Keith's face.  What Connan Doyle had
actually written was, "Eliminate the impossible, and whatever remains,
however improbable, must be the truth," but considering that the words
had been translated into Waldahudar then back into English, Jag's
version wasn't half-bad.

"Yes?"  said Keith.

"Well, my original analysis, that the fourth-generation star that
appeared here was a one-of-a-kind anomaly, must now be amended, since
we've seen a second such star at Rehbollo 376A.  By applying Holmes's
dictum, I believe I now know where these two green stars, and presumably
the other rogue stars as well, have come .from."  Jag fell silent,
waiting for Keith to prod him further.

"And that is?"  Keith said, irritated.

"The future."

Keith laughed--but then, he had a barking laugh; perhaps it didn't sound
derisive to Waldahud ears.  "The future?"

"It is the best explanation.  Green stars could not have evolved in a
universe that is as young as ours is.  A single such star could have
been a freak, but multiple ones 'are highly unlikely."

Keith shook his head.  "But perhaps they come from--I don't know--some
unusual region of space.  Maybe they had been companions of a black
hole, and the gravitational stresses had caused fusion reactions to
proceed more quickly."

"I thought of such things," said Jag.  "That is, I thought of probable
alternative scenarios, of which that is not one.  But none of them fits
the facts.  I have now done radiometric dating, based on isotope
proportionalities, of the material Longbottle and I scooped from the
atmosphere of the green star near us.  The heavy-metal atoms in that
star are twenty-two billion years old.  The star itself is not that old,
of course, but many of the atoms it is composed of are."

"I thought all matter was the same age," said Keith.

Jag lifted his lower shoulders.  "It's true that, excepting the small
amount of matter constantly being created out of energy, and excepting
that in certain reactions neutrons can essentially turn into.

proton-electron pairs, and vice versa, all fundamental particles in the
universe were created shortly after the big bang.  But the atoms made up
of those particles can be formed or destroyed at any time, through
fission or fusion."

"Right," said Keith, embarrassed.  "Sorry.  So you're saying the
heavy-metal atoms in the star formed longer ago than the universe is
old."

"That's correct.  And the only way that could happen is if the star came
to us from the future."

"But--but you said the green stars are billions of years older than any
current star could be.  You're trying to tell me that these stars have
traveled back in time billions of years?

That seems incredible."

Jag preceded his barking reply with a snort.  "The intellectual leap
should be in the acceptance of time travel, not the length of time an
object is cast back.  If time travel can exist at all, then the distance
traveled back surely is only a function of appropriate technology and
sufficient energy.  I submit that any race that has the power to move
stars around has both in abundance."

"But I thought time travel was impossible."

Jag lifted all four shoulders.  "Until the shortcuts were discovered,
instantaneous transportation was impossible.

Until the hyperdrive was discovered, faster-than-light travel was
impossible.  I cannot begin to suggest how time travel might be made to
happen, but apparently it is happening."

"There are no other explanations?"  asked Keith.

"Well, as I said, I have considered other possibilities--such as that
the shortcuts are now acting as gateways to parallel universes, and that
the green stars come from there rather than from our future.  But except
for their age, they are what one would expect of matter formed in this
specific universe, from our specific big bang, under the very specific
physical laws that operate here."

"Very well," said Keith, holding up a hand.  "But why send stars from
the future back to the past?"

"That," said Jag, "is the first good question you have asked."

Keith spoke through clenched teeth.  "And the answer is?"

Jag lifted all four shoulders again.  "I have no idea."

As he moved down the dim, cold corridor, Keith accepted that each of the
races aboard Starplex managed to piss the others off in different ways.

One of the things humans did that he knew bugged the hell out of
everyone else was spending endless time trying to come up with cute
words made from the initial letters of phrases.  All the races called
such things "acronyms" now, since only the Terran languages had a word
for them.  Early on in planning Starplex, some human came up with the
term CAGE for "Common Access General Environment," referring to the
shipboard conditions in those areas that had to be shared by all four
races.

Well, it felt like a goddamned cage, thought Keith.  Like a dungeon.

All the races could exist in nitrogen-oxygen atmospheres, although Ibs
required a much higher concentration of carbon dioxide to trigger their
breathing reflex than humans did.  Common-area gravity ended up being
set at .82 of Earth's--normal for a Waldahud, light for a human or
dolphin, and only half of what an Ib was used to.  Humidity was kept
high, too: Waldahud sinuses seized if the air was too dry.  Common-area
lighting was redder than humans liked--similar to a bright terrestrial
sunset.  Further, all lighting had to be indirect.  The Ib homeworld was
perpetually shrouded in cloud, and the thousands of photosensors in
their webs could be damaged by bright lighting.

Even so, there were still problems.  Keith moved to one side of the
corridor to let an Ib roll by, and as it passed, one of the two dangling
blue tubes coming off the creature's pump pushed out a hard gray pellet,
which fell to the corridor floor.  The pod's brain had no conscious
control over this function; for Ibs, toilet training was a biological
impossibility.  On Flatland, the pellets were scooped up by scavengers
that reprocessed them for the nutrients the Ib had been unable to use.

Aboard Starplex, little PHARTs the size of human shoes served the same
function.  One such came zipping along the corridor as Keith watched.

It sucked up the dropping and rolled upon its way.

Keith had finally gotten used to the Ibs defecating everywhere; thank
God their feces had no discernible odor.

But he didn't think he'd ever get used to the cold, or the damp, or any
of the other things forced upon them by the Waldahudin-- Keith stopped
dead in his tracks.  He was coming to a T-intersection in the corridor,
and could hear raised voices up ahead: a human male shouting
in--Japanese, it sounded like--and the angry barking of a Waldahud.

"PHANTOM," Keith said softly, "translate those voices for me."

A New York accent: "You are weak, Teshima.  Very weak.

You don't deserve a mate."

"Have sex with yourself!"  Keith frowned, suspecting the computer wasn't
doing justice to the original Japanese.

The New York accent again: "On my world, you would be the least
significant member of the entourage of the ugliest, puniest female--"

"Identify the speakers," Keith whispered.

"The human is Hiroyuki Teshima, a biochemist," said PHANTOM through
Keith's implant "The Waldahud is Gatt Daygaro em-Holf, a member of the
engineering staff."

Keith stood there, wondering what to do.  They were both adults, and
although they reported to him, they could hardly be said to be under his
command.  And yet-- Middle child.  Keith stepped around the corridor.

"Guys," he said evenly, "you want to cool it?"

All four of the Waldahud's fists were clenched.  Teshima's round face
was flushed with anger.  "Stay out of this, Lansing," said the human, in
English.

Keith looked at them.  What could he do?  There was no brig to throw
them into, no particular reason why they had to listen to his orders
about their personal affairs.

"Maybe I could buy you a drink, Hiroyuki," said Keith.

"And, Gart, perhaps you'd enjoy an extra leisure period this cycle?"

"What I would enjoy," barked the Waldahud, "is seeing Teshima f'ued
through a mass driver into a black hole."

"Come on, guys," said Keith, stepping closer.  "We've all got to live
and work together."

"I said stay out of this, Lansing," snapped Teshima.  "It's none of your
damned business."

Keith felt his cheeks flushing.  He couldn't order them apart, and yet
he couldn't have people brawling in the corridors of his ship, either.

He looked at the two of them--a short, middle-aged human, with hair the
color of lead, and a fat, wide Waldahud, with fur the shade of oak wood.

Keith didn't know either of them well, didn't know what it would take to
placate them.  Hell, he didn't even know what they were fighting about.

He opened his mouth to say--to say something, anything--when a door slid
open a few meters away, and a young woman--Cheryl Rosenberg, it
was--appeared, wearing pajamas.  "For Pete's sake, will you keep it down
out here?"  she said.  "It's nighttime for some of us."

Teshima looked at the woman, bowed his head slightly, and began to walk
away.  And Gatt, who likewise by nature was deferential to females,
nodded curtly and moved in the other direction.  Cheryl yawned, stepped
back inside, and the door slid shut behind her.

Keith was left standing there, watching the Waldahud's back recede down
the corridor, angry with himself for not being able to deal with the
situation.  He rubbed his temples.

We're all prisoners of biology, he thought.  Teshima unable to turn down
the request of a pretty woman; Gatt unable to disobey a female's orders.

Once Gart had disappeared from sight, Keith headed down the cold, damp
hallway.  Sometimes, Keith thought, he'd give anything to be an alpha
male.

Rissa was sitting at her desk, doing the part of her job she hated--the
administrative duties, the burden still called paperwork even though
almost none of it was ever printed out.

The door buzzer sounded, and PHANTOM said, "Boxcar is here."

Rissa put down her input stylus and straightened her hair.

Funny that, she thought--worrying about whether her hair was messy when
the only one going to see it isn't even human.  "Let her in."

The Ib rolled in; PHANTOM slid the polychairs to one side to make room
for her.  "Please forgive my disturbing you, good Rissa," said the
beautiful British voice.

Rissa laughed.  "Oh, you're not disturbing me, believe me.  Any
break is
welcome."

Boxcar's sensor web arched up like a ship's sail so that she could see
onto Rissa's desktop.  "Paperwork," she said.

"It does look boring."

Rissa smiled.  "That it is.  So, what can I  do for you?"

There was a long pause--unusual from an Ib.  Then, finally, "i've come
to give notice."

Rissa looked at her blankly.  "Notice?"

Lights danced on her web.  "Profound apologies, if that.  is not the
correct phrase.  I mean to say that, with regret, I will no longer be
able to work here, effective five days from now."

Rissa felt her eyebrows lifting.  "You're quitting?  Resigning?"

Lights played up the web.  "Yes."

"Why?  I thought you were enjoying the senescence research.  If you wish
to be assigned to something else--"

"It is not that, good Rissa.  The research is fascinating and valuable,
and you have honored me by letting me be a part of it.  But in five days
other priorities must take precedence."

"What other priorities?"

"Repaying a debt."

"To whom?"

"To other integrated bioentities.  In five days, I must go."

"Go where?"

"No, not go.  Go."

Rissa exhaled, and looked at the ceiling.  "PHANTOM, are you sure you're
translating Boxcar's words correctly?"

"I believe so, ma'am," said PHANTOM into her implant.

"Boxcar, I don't understand the distinction you're making between 'go'
and 'go,'" said Rissa.

"I am not going someplace in the physical sense," said

Boxcar.  "I am going in the sense of exiting.  I am going to die."

"My God!"  said Rissa.  "Are you ill?"

"No."

"But you're not old enough to die.  You've told me enough times that Ibs
live to be exactly six hundred and forty-one.  You're only a little over
six hundred."

Boxcat's sensor web changed to a salmon color, but whatever emotion that
conveyed apparently had no terrestrial analog, since PHANTOM didn't
preface the translation of her next words with a parenthetical comment.

"I am six hundred and five, measured in Earth years.  My span is about
to be fifteen-sixteenths completed."

Rissa looked at her.  "Yes?"

"For offenses committed in my youth, I have been assessed a penalty of
one-sixteenth of my lifespan.  I am to be ended next week."

Rissa looked at her, unsure what to say.  Finally, she settled for
simply repeating the word "ended," as if perhaps it, too, had been
mistranslated.

"That is correct, good Rissa."

She was quiet again for a moment.  "What crime did you commit?"

"It shames me to discuss it," said Boxcar.

Rissa said nothing, waiting to see if the Ib would go on.

She did not.

"I've shared a lot of intimate information about myself and my marriage
with you," said Rissa lightly.  "i'm your friend, Boxcar."

More silence; perhaps the Ib was wrestling with her own feelings.  And
then: "When I was a tertiary novice--a position somewhat similar to what
you call a graduate student--I reported incorrectly the results of an
experiment I was conducting."

Rissa's eyebrows rose again.  "We all make mistakes, Boxcar.  I can't
believe they'd punish you this severely for that."

Boxcar's lights rippled in random patterns.  Apparently, they were just
signs of consternation; again, PHANTOM provided no verbal translation.

Then: "The results were not accidentally misreported."  The Ib's mantle
was dark for several seconds.  "I deliberately falsified the data."

Rissa tried to keep her expression neutral.  "Oh."

"I did not think the experiment was of great significance, and I
knew--thought I knew, anyway--what the results should be.  In
retrospect, I realize I only knew what I wanted them to be."  Darkness;
a pause.  "In any event, other researchers relied upon my results.

Much time was wasted."

"And for this they're going to execute you?"

All the lights on Boxcar's web came on at once--an expression of
absolute shock.  "It is not a summary execution, Rissa.  There are only
two capital crimes on Flatland:

pod murder and forming a gestalt with more than seven components.  My
lifespan has simply been shortened."

"But--but if you're six hundred and five now, how long ago did you
commit this crime?"

"I did it when I was twenty-four."

"PHANTOM, what Earth year would that have been?"

"^.). 1513, ma'am."

"Good God!"  said Rissa.  "Boxcar, surely they can't punish you for a
minor offense committed that long ago."

"The passage of time has not changed the impact of what I did."

"But so long as you're aboard Starplex, you're protected by the
Commonwealth Charter.  You could claim asylum here.  We could get you a
lawyer."

"Rissa, your concern touches me.  But I am prepared to pay my debt."

"But it was so long ago.  Maybe they've forgotten."

"Ibs cannot forget; you know that.  Because matrices form in our pod
brains at a constant rate, we all have eidetic memories.  But even if my
compatriots could forget, it would not matter.  I am honor bound in
this."

"Why didn't you say anything about this earlier?"

"My punishment did not require public acknowledgment; I was allowed to
live without constant shame.  But the terms under which I work here
require me to give you five days' notice if I intend to leave.  And so
now, for the first time in five hundred and eighty-one years, I am
telling someone of my crime."  The Ib paused.  "If it is acceptable, I
will use the remaining days of my life putting our research in order so
that you and others may continue it without difficulty."

Rissa's head was swimming.  "Um, yes," she said at last.

"Yes, that would be fine."

"Thank you," said Boxcar.  She turned and started to roll toward the
door, but then her web flashed once more.  "You have been a good friend,
Rissa."

And then the door slid open, Boxcar rolled away, and Rissa slumped back
in her chair, dumbfounded.

Chapter XII

Rissa came to the bridge, wanting to talk to Keith about Boxcar's
announcement.  But just as she was striding toward his workstation,
Rhombus spoke up.  "Keith, Jag, Rissa," he said, in his crisp, cool
translated voice, "innumerable apologies for the interruption, but I
think you should see this."

"What is it?"  said Keith.

Rissa took a seat as Rhombus's ropes tickled his console.

A section of the holo bubble became framed off in blue.  "I wasn't
paying enough attention to the real-time scans, I'm afraid," said the
Ib, "but I've been reviewing the data we've been recording, and--well,
watch this.  This is a playback speeded up one thousand times.  What
you're going to see in the next six minutes took almost all of the time
we've been here to occur."

In the framed-off area was a dark-matter sphere, seen from almost
directly above its equator.  Actually, it wasn't anywhere near a perfect
sphere: this one was flattened at the poles.  Light and dark latitudinal
cloud bands crossed its face.

According to the scale bars, this was one of the largest spheres they'd
found, measuring 172,000 kilometers in diameter.

"Wait a minute," said Keith.  "It's got cloud bands, yet it doesn't seem
to be spinning at all."

Rhombus's web twinkled.  "I hope the truth does not prove embarrassing,
good Keith, but in fact, it's spinning faster than any other sphere
we've yet observed.  At this point, it's rotating on its axis once every
two hours and sixteen minutes--almost five times as fast as Jupiter
revolves.  The speed is so great that any normal turbulence in the
clOUds has been smoothed out.

And in this speeded-up playback, the image you're seeing is rotating
every eight seconds."  Rhombus snaked out a rope and flicked a control.

"Here, let me have the computer put a reference mark on the equator.

See that orange dot?  It's at an arbitrary zero degrees of longitude."

The orange spot whipped across the equator, disappeared around back,
reappeared four seconds later, and traversed the visible face again.

After a few cycles, Jag barked out, "Are you increasing the playback
speed?"

"No, good Jag," said Rhombus.  "Speed is constant."

Jag gestured at the digital clocks.  "But that dot of yours took only
seven seconds to go around that time."

"Indeed," said Rhombus.  "The sphere's actual rate of rotation is
increasing."

"How can that be?"  asked Keith.  "Are other bodies interacting with
it?"

"Well, yes, the other spheres are all having an effect on it--but that's
not the cause of what we're seeing," said Rhombus.  "The increased
rotation is internally generated."

Jag's head was bent down to his console, running quickie computer
models.  "You can't get increased spin unless you pump energy into the
system.  There must be some complex reactions going on inside the
sphere, ultimately fueled by some outside source, and--" He looked up,
and let out a high-pitched bark, which PHANTOM translated as "Expression
of astonishment."

In the blue framed-off area, the dark-matter object had started-to pinch
in at its equator.  The northern and southern halves were no longer
perfect hemispheres, but rather they curved in a little before they
joined each other.  The orange reference dot was now whipping around the
smaller waist even faster than before.

As the sphere continued to rotate with increasing speed, the
pinching-off became more and more pronounced.  Soon the profile of the
object had taken on a figure-eight shape.

Rissa rose to her feet, and stood staring, mouth agape.

The equator was now so narrow that the orange dot covered almost a
quarter of its width.  Rhombus touched some keys and the dot
disappeared, replaced by separate orange dots on the equators of each of
the two joined spheres.

The view in the frame went dark.  "Please forgive this," said Rhombus.

"Another dark-matter sphere moved into our line of sight, obscuring the
view.  At this playback speed, we lose the picture for about fourteen
seconds.  Let me jump past that,"

Ropes touched the ExOps console.  When the image reappeared, the two
spheres were joined by only about a tenth of the original globe's
diameter.  Everyone watched, rapt, silence broken only by the gentle
whir of the air-conditioning equipment, as the process reached its
inevitable conclusion.  The two spheres broke free from each other.

One immediately started curving toward the bottom of the frame; the
other, toward the top.  As they distanced themselves from each other,
the orange reference dots on each of their equators began to take longer
and longer to complete their paths--the rotation was slowing down.

Rissa turned to face Keith, her eyes wide.  "It's like a cell," she,
said.  "A cell undergoing mitosis."

"Exactly," said Rhombus.  "Except that in this case, the mother cell is
some hundred and seventy thousand kilometers in diameter.  Or, at least
it was before this started happening."

Keith cleared his throat.  "Excuse me," he said.  "Are you trying to
tell me that those things out there are alive?  That they're living
cells?"

"I finally saw the recordings Jag's atmospheric probe had made," said
Rissa.  "Remember that blimplike object it saw as it went into the
atmosphere?  I'd idly thought that it might be an individual
life-form--a gasbag creature, floating in the clouds.  Earth scientists
in the 1960s proposed just such life-forms for Jupiter.  But such blimps
could just as easily be organelles--discrete components within a larger
cell."

"Living beings," said Keith, incredulous.  "Living beings almost two
hundred thousand kilometers in size?"

Rissa's voice was still full of awe.  "Perhaps.  In which case, we've
just seen one of them reproduce."

"Incredible," said Keith, shaking his head.  "I mean, we aren't just
talking about giant creatures.  And we aren't just talking about
life-forms living freely in open space.  We're talking about living
beings made of dark matter."  He turned to his left.  "Jag, is that even
possible?"

"Possible that dark matter--or some portion of it--is alive?"  The
Waldahud shrugged all four shoulders.  "Much of our science and
philosophy tell us that the universe should be teeming with life.  And
yet, so far, we've only found three worlds on which life has arisen.

Perhaps we've just been looking in the wrong places.  Neither Dr.
Delacorte nor I has yet figured out much about dark-matter
meta-chemistry, but there are lots of complex compounds in those
spheres."

Keith spread his arms in an appeal for basic common sense, and looked
around the bridge, trying to find someone else as lost by all this as he
was.

And then an even bigger thought hit him, and he leaned back in his chair
for a moment.  Then he touched his comm control panel, selecting a
general channel.  "Lansing to Hek," he said.

A hologram of Hek's head appeared in a second framed-off part of the
starscape.  "Hek here."

"Any luck pinpointing the sources of those radio transmissions?"

Keith imagined the Waldahud's lower shoulders moving outside the
camera's field of view.  "Not yet."

"You said there were over two hundred separate frequencies upon which
you were finding apparently intelligent signals."

"That's right."

"HOW many?  Exactly how many?"

Hek's face turned to a profile view, showing his projecting snout, as he
consulted a monitor.  "Two hundred and seventeen," he said.

"Although some are much more active than others."

Keith heard Jag, on his left, repeat the same bark of astonishment he'd
made earlier.

"There are," said Keith slowly, "precisely two hundred and seventeen
separate Jupiter-sized objects out there."  He paused, backtracking away
from his own conclusion.  "Of course, gas-giant worlds like Jupiter are
often sources of radio emissions."

"But these are spheres of dark matter," said Lianne.

"They're electrically neutral."

"They are not pure dark matter," said Jag.  "They're permeated with bits
of regular matter.  The dark matter Could interact with protons in the
regular matter through the strong nuclear force, thereby generating EM
signals."

Hek lifted his upper shoulders.  "That might work," he said.  "But each
sphere is broadcasting on its own separate frequency, almost like .

.

." The Brooklyn-accented voice trailed off.

Keith looked at Rissa, and could see that she was thinking the same
thing.  He lifted his eyebrows.  "Almost like separate voices," he said
at last, finishing the thought.

"But there aren't two hundred and seventeen objects anymore," said Thor,
turning around.  "There are two hundred and eighteen now."

Keith nodded.  "Hek, do another inventory of signals.  See if there's
new activity at a frequency just above or just below the block of
frequencies you've identified as being active."

Hek tilted his head as he worked his controls up on deck one.  "Just a
second," he said.  "Just a second."  Then: "Gods of the mud and the
moons, yes!  Yes, there is!"

Keith turned to Rissa, grinning.  "I wonder what baby's first words
were?"

**EPSILON DRACONIS**

Keith hadn't seen Glass reenter the docking bay, but when he looked up,
there he was, coming closer, transparent legs carrying him over the
fields of grass and four-leaf clover.

His walking was fluid, beautiful, giving the appearance of being in slow
motion even though he was moving at normal speed.  The hint of
aquamarine--the only color in his clear body--was eye-catching.

Keith thought about rising to his feet but instead simply looked up at
the transparent man, sun glinting off the latter 's body and egg-shaped
head.

"Welcome back," said Keith.

Glass nodded.  "I know, I know.  You're frightened.  You hide it well,
but you're wondering how much longer I will keep you here.  It won't be
long, I promise.  But there is something else I want to explore with you
before you go."

Keith lifted his eyebrows, and Glass sat down, leaning his back against
a nearby tree.  Whatever his body was made of wasn't glass.  His tubular
torso didn't magnify the patterns of the bark on the other side of it.

Rather, they were seen with only slight distortion.

"You are angry," said Glass, simply.

Keith shook his head.  "No, I'm not.  You've treated me well so far."

The wind-chime laughter.  "No, no.  I don't mean you're angry with me.

Rather, you're angry in general.  There's something inside you,
something down deep, that has hardened your heart."

Keith looked away.

"I'm right, aren't I?"  said Glass.  "Something that has upset you
greatly."

Silence.

"Please," said Glass.  "Share it with me."

"It was a long time ago," said Keith.  "I--I should be over it, I know,
but .  . ."

"But it festers still, doesn't it?  What is it?  What changed you so?"

Keith sighed, and looked around.  Everything was so beautiful, so
peaceful.  He couldn't remember the last time he'd sat outside among the
grass and trees, and just enjoyed the surroundings, just--just relaxed.

"It has to do with Saul Ben-Abraham's death," said Keith.

"Death," repeated Glass, as if Keith had used another unknown word like
"quixotic."  He shook his see-through head.  "How old was he when he
died?"

"It was eighteen years ago now.  He would have been twenty-seven."

"A heartbeat," sam Glass.

There was silence between them for a moment, Keith recalling his
reaction when Glass had dismissed his two decades of marriage in a
similar fashion.  But Glass was right this time.  Keith nodded.

"How did Saul die?"  asked Glass.

"It--it was an accident.  At least, that's what the HuGo decided.  But,
well, I always thought it was swept under the rug.  You know:
deliberately suppressed.  Saul and I were living on Tau Ceti IE.  He was
an astronomer; I was a sociologist, doing a postdoctoral fellowship
studying the colonists there.  He and I had been friends since our
undergrad days; we'd been roommates at UBC.  And we had d lot in
common--both liked to play handball and go, both acted in StUdent
theater, both had the same tastes in music.

Anyway, Saul discovered the Tau Ceti shortcut, and we sent a smallprobe
through it to Shortcut Prime.  New Beijing was a mostly agricultural
colony back then, not the thriving place it is now.  Of course, it
hadn't yet acquired the New Beijing nickname.  It was just "the Silvanus
colony' then; Silvanus is the name of Tau Ceti's fourth planet.  Anyway,
they didn't have many sociologists there, so I ended up in charge of
trying to figure out what effect the discovery of the shortcut network
would have on human culture.  And then the Waldahud starship popped
through.  A first-contact team had to be hastily assembled; even under
hyperdrive, it would take six months for people to arrive from Earth.

Saul and I ended up being part of the party that went up to meet the
ship, and .  . ."  Keith trailed off, closed his eyes, shook his head
ever so slightly.

"Yes?"  said Glass.

"They said it was an accident.  Said they'd misinterpreted.  When we
cameface-to-face with the Waldahudinfor the first time, Saul was
carrying a holographic camera unit.

He didn't aim it at the pigs, of course--no one could be that stupid.

He was just holding it at his side, and then, with a flick of his thumb,
he turned it on."  Keith sighed, long and loud.  "They said it looked
like a traditional Waldahud hand weapon--same basic shape.  They thought
Saul was readying a weapon to fire on them.  One of the pigs was
carrying a sidearm, and he shot Saul.  Right in the face.  His head
exploded next to me.  I--I got splattered with...

with .  . ."  Keith looked away, and was quiet for a long moment.

"They killed him.  The best friend I ever had, they killed him."  He
stared at the ground, plucked a few four-leaf clovers, looked at them
for a moment, then threw them away.

hey were quiet for several moments.  Crickets chirped, and birds sang.

Finally, Glass said, "That must be difficult to carry around with you."

Keith said nothing.

Does Rissa know?"

"She does, yes.  We were already married at that point; she'd come to
Silvanus to try to fathom why it didn't have any native life, despite
apparently having conditions that should have given rise to it,
according to our evolutionary models.  But I rarely talk about what
happened with Saul--not with her, or with anyone else.  I don't believe
in burdening those around me with my suffering.  Everyone has their own
stuff to deal with."

"So you keep it inside."

Keith shrugged.  "I try for a certain stoicism--a certain emotional
restraint."

"Commendable," said Glass.

Keith was surprised.  "You think so?"

"It's the way I feel, too.  I know it's unusual, though.  Most people
live, if you'll pardon me my humor, transparent lives."  Glass gestured
at his own see-through body.  "Their private self is their public self
Why are you different?"

Keith shrugged.  "I don't know.  I've always been this way."  He paused
again, thinking for a long time.  Then: "When I was about nine or so,
there was a bully in my neighborhood.  Some big oaf, probably thirteen
or fourteen.

He used to pick up kids and drop them into this thombush in the park.

Well, everyone would kick and scream and cry while he was doing this,
and he seemed to feed off that.  One day, he came after me--grabbed me
when I was playing catch, or something like that.  He picked me up,
carried me over to the bush, and dumped me in.  I didn't struggle.

There was no point; he was twice as big as me, and there was no way I
could get away.  And I didn't scream or cry, either.  He dumped me in,
and I simply got myself out.  I had a few scrapes and cuts from it, but
I didn't say anything.  He just looked at me for about ten seconds, then
said, 'Lansing, you've got balls.  'And he never touched me again."

"So this internalizing is a survival mechanism?"  asked Glass.

Keith shrugged.  "It's enduring what you have to endure."

"But you don't know where it came from?"

"No," said Keith.  Then, a moment later, "Well, actually, yes.  I

suppose I do.  My parents were both quite argumentative, and had short
fuses.  You'd never know when one of them was going to blow up over
something.  Publicly, privately, it didn't make any difference.  You
couldn't even make polite conversation without risking an explosion from
one of them.  We'd have family dinners together every night, but I
always was silent, hoping we could just get through it, just once,
without it being unpleasant, without one of them storming away from the
table, or yelling, or saying something nasty."

Keith paused again.  "In fairness, there were other issues in my
parents' relationship that I didn't understand when I was a child.

They'd started as a two-career family, but automation kept eliminating
more and more jobs as the years went by--this was back before they
outlawed true artificial intelligence.  The Canadian government changed
the tax laws so that second income earners in a family were taxed at a
hundred-and-ten-percent rate.  It was a move designed to spread out what
work there was amongst the most families.  Dad had been making less than
mom, so he was the one who stopped working.  I'm sure that had a lot to
do with his anger.  But all I knew was that my parents were taking out
their anger and frustration on everyone around them, and even as a kid,
I vowed never to do that."

Glass was rapt.  "Amazing," he said.  "It all makes sense."

"What does?"  asked Keith.

"You."

Chapter XIII

Keith's mind was reeling.  So many discoveries, so much happening.  He
drummed his fingers on his bridge workstation for a moment, thinking.

And then: "Okay, people, what now?"

The front row of workstations all rotated around on their individual
pedestals so that they faced the back row: Lianne was facing Jag, Thor
was facing Keith, and Rhombus was facing Rissa.  Keith looked at each
member of his bridge staff in turn.  "We've got almost an embarrassment
of riches here," he said.  "First, there's the mystery of the stars'
erupting from the shortcuts--stars that Jag thinks come from the future.

As if that's not a big enough puzzle to try to figure out, we've also
stumbled upon life--life!--made out of dark matter."  Keith looked from
face to face.  "Given the complexity of the radio signals Hek's been
picking up, there's a chance--a small one, I grant you--that we're even
looking at first contact with intelligent life.  Rissa, it would have
been crazy to say this yesterday, but let's make the dark-matter
investigations the province of the life- sciences division."

She nodded.

Keith turned to Jag.  "The stars coming out of the shortcuts, on the
other hand, may pose a threat to the Commonwealth.  If you're right,
Jag, and they are coming from the future, then we've got to find out why
they're coming back.  Is it by deliberate design?  If so, is it for a
malevolent purpose?  Or is it just an accident?  A globular cluster,
say, colliding with a shortcut billions of years from now, and
overloading it somehow so that its constituent stars are spewed back to
here?"

"Well," barked Jag, "a globular cluster wouldn't pass through a
shortcut.  Only one of its member stars would."

"Unless," said Thor, sounding a bit feisty, "that globular cluster was
enclosed in a sort of super Dyson sphere--a shell around the entire
assembly of stars.  Imagine something like that touching a shortcut
billions of years from now.  The shell could break apart while
traversing the gate, and send the component stars scattering out of
different exit points."

"Ridiculous," said Jag.  "You humans always reinforce each other in even
your wildest fantasies.  Take your religions, for instance--"

"Enough!"  snapped Keith, bringing his open palm down loudly on the edge
of his workstation.  "Enough.  We're not going to get anywhere
squabbling."  He looked at the Waldahud.  "If you don't like Thor's
suggestion, then make one of your own.  Why are the stars coming back
here from the future?"

Jag was facing the director, but only his right eyes were looking at
Keith; the left pair was scanning the surroundings, an instinctual
precursor to a fight.  "I don't know," he said at last.

"We need an answer," said Keith, his voice still edged.

"Interrupting in all politeness," said Rhombus.  "Offense not intended
and hopefully not taken."

Keith turned to face the Ib.  "What is it?"

"Perhaps you are asking the wrong person.  No slight is intended of good
Jag, of course.  But if you want to know why the stars are being sent
back in time, then the person to ask is the person who is sending them
back."

"You mean ask some person in the future?"  Keith said.

"How can we possibly do that?"

The Ib's mantle twinkled.  "Now that is a question for good Jag," he
said.  "If material from the future can exit the shortcut in the past,
can we then send something from the past into the future?"

Jag was quiet for a second, thinking.  But then he moved his lower
shoulders.  "Not as far as I can tell.  Every computer simulation I've
done shows that any object entering the shortcut in the present gets
shunted to another present-day shortcut.  Assuming the rogue stars are
being sent back by conscious design, I don't know how whoever is
controlling the shortcuts is doing it, and I have no idea how to send
something forward."

"Ah, good Jag," said Rhombus, "forgive me, but there is of course one
way to send something forward."

"And what's that?"  Keith asked.

"A time capsule," said the Ib.  "You know: just make something that will
last.  Eventually, without our doing anything special, it will end up in
the future through the natural passage of time."

Jag and Keith looked at each other.  "But--but Jag says the stars are
coming from billions of years in the future," Keith said.

"In fact," said the Waldahud, "if I had to guess, I would say they come
from something like ten billion years from now."

Keith nodded, turning back to face Rhombus.  "That's double the current
age of any of the Commonwealth homeworlds."

"True," said the Ib.  "But, forgive me, despite what you Humans think,
neither Earth nor the other homeworlds were created by deliberate
design.  Our time capsule would be."

"A time capsule that would last ten billion years .  . ."

said Jag, clearly intrigued.  "Perhaps .  . . perhaps if it were made
out of extremely hard material, like .  . . like diamond, but without
the cleavage planes.  But even if we made such a thing, there is no
guarantee that anyone would ever find it.  And, besides, this part of
the galaxy will rotate around the core forty-odd times before then.

How do we possibly keep the object from drifting away from during all
that time?"

Lights danced on Rhombus's sensor web.  "Well, assume that this
particular shortcut will continue to exist for the next ten billion
years; that's a fair assumption, since it's here now, and must also
still exist at the time the star was pushed through it.  So, make our
time capsule self-repairing--the nanotech lab should be able to come up
with something--and have it hold position near this shortcut."

"And then just hope that someone will notice it when they come by here
in the future to use the shortcut?"  asked Keith.

"It may be more than that, good Keith," said Rhombus.

"It may be that they come by here to build the shortcut.  The shortcuts
may have been created in the future, and had their exit points extruded
into the past.  If their real purpose is to shunt stars back here, then
that's a likely scenario."

Keith turned to Jag.  "Objections?"

The Waldahud lifted all four shoulders.  "None."

He turned back to Rhombus.  "And you think this will work?"

A tiny flash of light on the Ib's sensor web.  "Why not?"

Keith thought about it.  "I suppose it's worth a try.  But ten billion
years--all of the Commonwealth races might be extinct by then.  Hell,
they'll probably be extinct by then."

Lights moved up Rhombus's web; a nod of assent.  "So we'll have to
contrive our message in symbolic or mathematical language.  Ask our good
friend Hek to devise something.  As a radio astronomer involved with
searching for alien intelligence, he's an expert in designing symbolic
communication.  To use an expression that both your people and mine
share, this project will be right up his alley."

The bridge was bustling with activity, and there was plenty of work to
be done.  But Jag and Hek were visibly flagging.

Although they didn't do the theatrical yawns humans were famous for,
their nostrils were dilating rhythmically, a physiological response that
amounted to the same thing.

Keith thought for a moment that he could pull an allnighter.  Hell, he'd
done that often enough at university.

But university had been a quarter century ago, and he had to admit that
he, too, was exhausted.

"Let's call it a night," he said, rising from his workstation.

The indicators on it went dark as he did so.

Rissa nodded and rose as well.  The two of them headed toward one of the
bridge's hologram-shrouded walls.  The door opened, exposing the
corridor beyond.  They headed down toward the elevator station.  A car
was waiting for them--PHANTOM had routed one there as soon as they had
started down the corridor.  Keith got in, followed by Rissa.  "Deck
eleven," he said, and PHANTOM chirped an acknowledgement.  They turned
around, just in time to catch sight of Lianne Karendaughter jogging down
the corridor toward them.  PHANTOM saw her, too, of course, and held the
elevator door open until she arrived.  Lianne smiled at Keith as she got
in, then called out her floor number.  Rissa affixed her gaze on the
wall monitor that showed the current level's deck plan.

Keith had been married to Rissa too long not to be sensitive to her body
language.  She didn't like Lianne--didn't like her standing this close
to Keith, didn't like being in a confined space with her.

The elevator began to move.  On the monitor, the arms of the floor plan
began to contract.  Keith breathed deeply--and realized, perhaps for the
first time, that he missed the subtle smell of perfume.  Another
concession to the damn pigs, and their hypersensitive noses.  Perfume,
cologne, scented aftershave--all were banned aboard Starplex.

Keith could see the reflection of Rissa's face in the monitor screen,
see the tight lines at the corners of her mouth, see the tension, the
hurt.

And Keith could also see Lianne.  She was shorter than he was, and her
lustrous blond hair half shielded her exotic, young face.  If they'd
been alone, Keith might have chatted with her, told her a joke, smiled,
laughed, maybe even touched her arm lightly as he made a comment.  She
was so--so alive; talking to her was invigorating.

Instead, he said nothing.  The deck-number indicator continued to count
down.  Finally, the car hummed to a stop on the floor containing
Lianne's apartment.

"Good night, Keith," said Lianne, smiling up at him.

"Good night, Rissa."

"Good night," replied Keith.  Rissa nodded curtly.

Keith was able to watch her walk down the corridor for a few seconds
before the door closed behind her.  He'd never been to her apartment.

He wondered how she had it decorated.

The elevator continued to ascend briefly and then it stopped again.

The door opened, and Keith and Rissa walked the short distance to their
apartment.

Once they were inside, Rissa spoke--and Keith could hear in her voice
that said she was speaking against her better judgment.  "You're quite
fond of her, aren't you?"

Keith weighed all the possible answers.  He had too much respect for
Rissa's intelligence to try to get away with saying, "Who?"  After a
moment's hesitation, he decided simple honesty was the best policy.

"She's bright, charming, beautiful, and good at her job.  What's not to
like?"

"She's twenty-seven," said Rissa, as if that were an indictable offense.

wenty-seven!  thought Keith.  Well, there it was.  A concrete number.

But--twenty-seven.  Jesus Christ .  . He took off his shoes and socks,
and lay down on the couch, letting his feet air out.

Rissa sat down opposite him.  Her face was a study in thought, as if she
were deciding whether to pursue the topic further.  Evidently she chose
not to, and instead changed the subject.  "Boxcar came to see me today."

Keith wriggled his toes.  "Oh?"

"She's quitting."

"Really?  Got a better offer somewhere else?"

Rissa shook her head.  "She's going to discorporate next week.  She was
assessed a penalty of one sixteenth of her lifespan because she wasted
some people's time almost six hundred years ago."

Keith was quiet for a few moments.  "Oh."

"You don't sound surprised," said Rissa.

"Well, I've heard of the procedure.  Never quite made sense to me, the
way Ibs are so obsessive about wasted time.

I mean, they live for centuries."

"To them, it's just a normal lifespan.  They don't think of it as
inordinately long, of course."  A pause.  "You can't let her go through
with it."

Keith spread his arms.  "I don't know that I have any choice."

"Dammit, Keith.  The execution is to take place here, aboard Starplex.

Surely you have jurisdiction."

"Over ship's business, sure.  Over this, well .  . ."  He looked up at
the ceiling.  "PHANTOM, what powers do I have in this area?"

"Under the Articles of Commonwealth Jurisprudence, you are obliged to
recognize all sentences imposed by the individual member governments,"
said PHANTOM.  "The Ib practice of exacting penalties equal to a portion
of the standard lifespan is specifically excluded from the section of
the articles that deals with cruel and unusual punishment.

Given that, you have no power to interfere."

Keith spread his arms, and looked at Rissa.  "Sorry."

"But what she did was so minor, so insignificant."

"You said she fudged some data?"

"That's right, when she was a student.  A stupid thing to do, granted,
but--"

"You know how the Ibs feel about wasted time, Rissa.  I imagine others
relied on her results, right?"

"Yes, but--"

"Look, the Ibs come from a planet that's perpetually shrouded in cloud.

You can't see the stars or their moons from the surface, and their sun
is only a bright smudge behind the clouds.  Despite that, by studying
tides in those shallow puddles that pass for oceans there, they managed
to work out the existence of their moons.  They even managed to deduce
the existence of other stars and planets, all before any of them had
ever traveled above their atmosphere.  The things they've figured out
would have been impossible for humans, I bet.  It's only because they
live for such a long time that they were able to puzzle them through; a
shorter-lived race on such a world would probably never have realized
that there was a universe out there.  But to accomplish what they have,
they have to be able to trust each other's observations and results.

It all falls apart if someone is monkeying with the data."

"But no one could possibly still care about what she did after all this
time.  And--and I need her.  She's an important part of my staff.  And
she's my friend."

Keith spread his arms.  "What would you have me do?"

"Talk to her.  Tell her she doesn't have to go through with this."

Keith scratched his left ear.  "All right," he said, at last.

"All right."

Rissa smiled at him.  "Thank you.  I'm sure she'll--" The intercom
chimed.  "Coloresso to Lansing," said a woman's voice.  Franca Coloresso
was the delta-shift InOps officer.

Keith tipped his head up.  "Open.  Keith here.  What is it, Franca?"

"A watson has come through from Tau Ceti, with a news report I think you
should see.  It's old news, in a way--sent from Sol to Tau Ceti by
hyperspace radio sixteen days ago.

As soon as Grand Central received it, they relayed it to us."

"Thanks.  Pipe it down to my wall monitor, please."

"Doing so.  Close."

Keith and Rissa both turned to face the wall.  It was the BBC World
Service, being read by an East Indian man with steel-gray hair.

"Tensions," he said, "continue between two of the Commonwealth
governments.  On one side: the United Nations of Sol, Epsilon Indi, and
Tau Ceti.  On the other, the Royal Government of Rehbollo.  Rumors of
further deterioration in the situation were fueled today by the terse
announcement that Rehbollo is closing three more embassies--New York,
Paris, and Tokyo.  Coupled with the four other closings a week ago, this
leaves only the Ottawa and Brussels embassies open in all of Sol system.

The consular staffs from the embassies closed today have already
departed on Waldahud starships for the Tau Ceti shortcut."

The view cut to a beefy Waldahud face.  The super at the bottom of the
screen identified him as Plenipotentiary Daht Lasko em-Wooth.  He spoke
in English, without aid of a translator--a rare feat for a member of his
race.  "It's with great regret that economic necessity has forced us
into this move.  As you know, the economies of all the Commonwealth
races have been thrown into disarray by the unexpected development of
interstellar commerce.  Reducing the number of our embassies on Earth
simply represents .an adjustment to the times."

The screen changed to show a middle-aged African woman, identified as
Rita Negesh, Earth-Wald Political Scientist, Leeds University.  "I don't
buy that--not for a minute," she said.  "If you ask me, Rehbollo is
recalling its ambassadors."

"As a prelude to what?"  asked an off-camera male voice.

Negesh spread her arms.  "Look, when humanity first moved out into
space, all the pundits said the universe is so big and so bountiful,
there was no possibility of material conflict between .separate worlds.

But the shortcut network changed all that; it forced us up close with
other races, perhaps before we or they were ready."

"And so?"  said the unseen questioner again.

"And so," said Negesh, "if we are moving toward an .  . . an incident,
it may not just be over economic issues.  It may be something more
basic--the simple fact that humans and Waldahudin get on each others'
nerves."

The wall monitor changed back to the holegram of Lake Louise.  Keith
looked at Rissa, and let out a long sigh.  "An 'incident,'" he said,
repeating the word.  "Well, at least we're both too old to be drafted."

Rissa looked at him for a long moment.  "I think that makes no
difference," she said, at last.  "I think we're already at the front
lines."

Chapter XIV

Keith always enjoyed taking an elevator to the docking bays.  The car
dropped down to deck thirty-one, the uppermost of the ten decks that
made up the central disk.  It then began a horizontal journey along one
of the four spokes that radiated out from there to the outer edge of the
disk.  But the spokes were transparent, as were the elevator cab's walls
and floors, and so the passengers were treated to a view looking down on
the vast circular ocean.  Keith could see the dorsal fins of three
dolphins swimming along just below the surface.  Agitators in the ocean
walls and central shaft produced respectable half-meter waves; dolphins
preferred that to a calm sea.  The radius of the ocean deck was
ninety-five meters; Keith was always staggered by the amount of water
contained there.  The roof was a real-time hologram of Earth's sky, with
towering white clouds moving against a background of that special shade
of blue that always tugged at Keith's heart.

The elevator finally reached the edge of the ocean and passed through
into the prosaic tunnels of the engineering torus.  Once it came to the
outer edge of the torus, it descended the nine levels to the floor of the
docking bays.

Keith disembarked, and walked the short distance to the entrance to bay
nine.  As soon as he entered, he saw Hek, the symbolic-communications
specialist, and a slim human named Shahinshah Azmi, the head of the
material-sciences department.  Between them was a black cube measuring a
meter on a side.  The cube was resting on a pedestal that brought it up
to eye level.  Keith walked over to them.

"Good day, sir," said the ever-polite Azmi, in a flat voice.

Keith knew from old movies how musical Indian accents used to be; he
missed the rich variety that human voices had had before instantaneous
communications had smoothed out all the differences.  Azmi gestured at
the cube.  "We've built the time capsule out of graphite composite with
a few radioactives added.  It's solid except for the self-repairing
hyperspatial sensor, which will lock onto the shortcut, and the
starlight-powered ACS system for helping the cube hold position relative
to it."

"And what about the message for the future?"  asked Keith.

Hek pointed to one of the cube's sides.  "We've incised it into the
cube's faces," he said, his barking echoing in the bay.  "It begins on
this side.  As you can see, it consists of a series of boxed examples.

Two dots plus two dots equals four dots; a question with its answer.

The second box, here, has two dots plus two dots, and a symbol.  Since
any arbitrary symbol would do, we just used the English question mark,
but without the separate dot underneath; that might confuse one into
thinking it was two symbols rather than one.  Anyway, that gives us a
question and a symbolic representation of the fact that the answer is
missing.  The third box shows the question symbol, the symbol I've
established for 'equals,' and four dots, the answer.  So that box says,
"The answer to the question is four. Do you see?"

Keith nodded.

"Now," continued Hek, "having established a vocabulary for our dialogue,
we can ask our real question."  He waddled around to the opposite side
of the cube, which was also incised with markings.

"As you can see," said Hek, "we have two similar boxes here.  The first
one has a graphic representation of the shortcut, with a star emerging
Ifrom it.  See that scale mark showing the width of the star, and the
series of horizontal and vertical lines beneath?  That's a binary
representation of the star's diameter in units of the box's width, in
case there's any confusion about what the image represents.  And then
there's the equals symbol, and the question symbol.  So it says,
'shortcut with star emerging from it equals what?'  And beneath it is
the question symbol, the equals symbol, and a large blank space: "The
answer to the above question is .  . ."  and a space implying that we
want a reply."

Keith nodded slowly.  "Clever.  Good work, gentlemen."

Azmi pointed to one of the cube's other faces.  "On this face, we've
incised information about the periods and relative positions of fourteen
different pulsars.  If the shortcut makers in the future--or whoever it
is who finds this--have records going back this far in time, they'll be
able to identify the specific year in which the cube was created from
that information."

"Beyond that," said Hek, "they might also assume, quite reasonably, that
the cube had been created shortly after the green star emerged from this
shortcut--and presumably they'll know what date they sent that star back
to, as well.

In other words, they've got two independent ways of determining when to
send any reply back to."

"And this will work?"  Keith asked.

"Oh, probably not," said Azmi, smiling.  "It's just a bottle in the
ocean.  I don't seriously expect any results, but I suppose it's worth a
try.  Still, as Dr. Magnor has told me, if we don't get a good
explanation, and if we decided the stars are a threat, we can use the
Waldahud space-flattening technique to evaporate the shortcuts.

Granted, stars may be popping out of thousands of exit points, so we
probably can't do much to stop them.  But if they know we have the
capability to interfere to some degree, perhaps they'll provide an
explanation rather than have us do that."

"Very good," said Keith.  "But what will make the cube conspicuous?

How can you be sure someone will find it?"

"That's the hardest part of all," barked Hek.  "There are only a few
ways to get something to stand out.  One is to make it reflective.  But
no matter what we make this box out of, it will have to endure perhaps
ten billion years of scouring by interstellar dust.  Granted, that's
only a few microscopic impacts per century, but the net effect over that
much time would be to dull any reflective surface.

"The second possibility we'd considered was to make the time capsule
big--so that it's eye-catching; or heavy--so.

that it warps spacetime.  But the bigger you make it, the more likely it
is to be destroyed by a meteor collision.

"The final possibility was to make it loud--you know, by broadcasting a
radio signal.  But that requires a power source.  Of course, right now
the green star is close by, and we can use simple solar cells to
generate electricity from it, but the star has a respectable proper
motion relative to the shortcut.  In just a few thousand years, it'll be
a full light-year from here, much too far away to provide significant
power.  And any internal power source we use would exhaust its fuel, or
have most of its radioactives decay to lead, long before the target
date."

Keith nodded.  "But you said you were using starlight converted to
electricity to power the attitude-control system?"

"Yes.  But there's almost no spare power for a beacon of any sort.

We're just going to have to assume that whoever built the shortcuts will
have detectors that will find the cube regardless."

"And if they don't?"

Hek moved all four shoulders up and down in a shrug.  "If they
don't--well, we've hardly lost much by trying."

"All right," said Keith.  "It looks good to me.  Is this a prototype, or
the actual time capsule?"

"We'd intended it as just a prototype, but everything came together
perfectly," said Azmi.  "!  say we might as well go ahead and use this
one."

Keith turned to Hek.  "What about you?"

The Waldahud barked once.  "I concur."

"Very well," said Keith.  "How do you propose to launch it?"

"Well, it has nothing but ACS jets," said Azmi.  "And I don't dare put
it out there on its own with those dark-matter creatures swarming
around; it would probably get sucked into their gravity.  But we've
already seen that the dark-matter beings have some mobility, so I'm
assuming they won't be in this exact spot forever.  I've programmed a
standard payload carrier to take the cube away from here, but come back
in a hundred years and dump it about twenty klicks from the shortcut.

After that, the time capsule's own ACS jets should be able to hold it in
place relative to the exit point."

"Excellent," said Keith.  "Is the launcher ready, too?"

Azmi nodded.

"Can you launch it from down here?"

"Of course."

"Let's do so, then."

The three of them exited the bay, and took a lift up to the docking
control room, which had angled windows that overlooked the interior of
the cavernous hangar.  Azmi took a seat in front of a console and began
operating controls.

Under his command, a motorized flatbed rolled into the bay, carrying a
cylindrical payload carrier.  Mechanical arms mated the cube to the
clamps on the front of the Carrier.

"Depressurizing the bay," said Azmi.

Shimmering forcefield sheets started to close in from three of the four
walls and the floor and ceiling, forcing the air in the bay out through
vents in the rear wall.  When all the air had been swept up and
compressed into tanks, the forcefield sheets collapsed, leaving an
interior vacuum.

"Opening space door," Azmi said, operating another control.  The
segmented curving outer wall began to slide up into the ceiling.

Blackness became visible, but the glare of the bay's internal lighting
washed out the stars.

Azmi touched some more buttons.  "Activating time-capsule electronics."

He then tapped a key, initiating a preprogrammed sequence for the
tractor-beam emitter mounted on the rear bay wall.  The payload carrier
lifted off the flatbed, flew over the floor plates, passed the spindly
form of a repair skiff that was parked inside the bay, and headed out
into space.

"Powering up carrier," said Azmi.  The cylinder's end lit up with the
glow of thrusters, and the contraption rapidly receded from view.

"And that," said Azmi, "is that."

"Now what?"  asked Keith.

Azmi shrugged.  "Now just forget about it.  Either this will work, or it
won't--probably won't."

Keith nodded.  "Excellent work, guys.  Thank you.  It's--"

"Rissa to Lansing," said a voice over the speakers.

Keith looked up.  "Open.  Hi, Rissa."

"Hi, hon.  We're ready to take our first whack at communicating with the
dark-matter creatures."

"I'm on my way.  Close."  He smiled at Azmi and Hek.

"Sometimes, you know, my staff is almost too efficient."

Keith rode up to the bridge and took his seat in the center of the back
row.  The holographic bubble was filled not with the normal space view
but rather with red circles against a pale white background, a plot of
the locations of the dark-matter spheres.

"Okay," said Rissa.  "We're going to try communicating with the
dark-matter beings using radio and visual signals.

We've deployed a special probe that will do the actual signaling.  It's
located about eight light-seconds off the starboard side of the ship;
I'm going to operate it by comm laser.  Of course, the dark-matter
beings may already have detected our presence, but, then again, they may
not have.

And just in case the dark-matter beings turn out to be the Slammers, or
something equally nasty, it seems prudent to have their attention drawn
to an expendable probe rather than Starplex itself."

"'Dark-matter beings,'" repeated Keith.  "That's a bit of a mouthful,
no?  Surely we can come up with a better name for them."

"How about 'darkies'?"  said Rhombus, helpfully.

Keith cringed.  "That's not a good idea."  He thought for a second, then
looked up, grinning.  "What about MACHO men?"

Jag rolled all four eyes and made a disgusted bark.

"How does 'darmats' sound?"  asked Thor.

Rissa nodded.  "Darmats it is."  She addressed everyone in the room.

"Well, as you all know, Hek has been cataloging the signal groups he's
picked up from the darmats.  On the assumption that each group is a
word, we've identified the single most commonly used one.  For the first
message, I'm going to send a looping repeat of that word.  We assume
it's innocuous--the darmat equivalent of 'the,' or some such.

Granted, the repetition will convey no meaningful information, but with
luck the darmats will recognize it as an attempt to communicate."  She
turned to Keith.  "Permission to proceed, Director?"

Keith smiled.  "Be my guest."

Rissa touched a control.  "Transmitting now."

Lights flashed on Rhombus's web.  "Well, that certainly did something,"
he said.  "The conversation level has increased dramatically.  All of
them talking at once."

Rissa nodded.  "We're hoping they'll triangulate on the probe as the
source."

"I'd say they've figured it out," said Thor, a moment later, pointing at
the display.  Five of the world-sized creatures had begun to move toward
the probe.

"Now the tricky part begins," said Rissa.  "We've got their attention,
but can we communicate with them?"

Keith knew that if anyone could pull it off, it would be his wife, who
had been part of the team that had first communicated with the Ibs.

That effort had started with a simple exchange of nouns--this pattern of
lights meant "table," that one meant "ground," and so on.  Even then,
there had been difficulties.  The Ib body was so different from the
bipedal human design that for many concepts they had no terms: stand up,
run, sit down, chair, clothing, male, female.  And because they'd always
lived under cloud cover, for countless other ideas--day, night, month,
year, constellation--there were no common Ibese words.

Meanwhile, the Ibs had been trying to convey concepts that were central
to their lives: biological gestalt, all-encompassing vision, and the
many metaphorical meanings for roll ahead and roll back.

But that exercise had been a piece of cake compared with communicating
with world-sized beings.  Indeed, the Ibs had had no trouble
understanding that particular metaphor--enjoyable, nonnutritive food
being equated with ease--just as humans had no difficulty with the Ibese
expression for the same sentiment, "downward slope."

Communicating with aliens as big as Jupiter who might or might not be
intelligent, might or might not be able to see, might or might not
understand any principle of physics or mathematics, could prove
impossible.

"The babble on all two hundred frequencies is continuing," said Rhombus.

Rissa nodded.  "But no way to tell if it's chatter amongst the spheres,
or responses aimed at us."  She touched another button.  "I'm going to
try again with a loop of a different, almost-as-common darmat word."

This time, the radio cacophony was halted by one darmat who was
apparently shushing the others.  And then that darmat repeated a simple,
three-word sentence over and over again.

"Time to play a hunch," said Rissa.

"How so?"  asked Keith.

"Well, the first question we would ask in a circumstance such as this
would be 'Who are you?"  Hek and I had PHANTOM sample all the darmat
words, and devise a signal that followed the apparent rules for valid
word construction but had not, as far as we've been able to detect, been
used by the darmats.  We hope they'll take this signal to be Starplex's
name."

Rissa broadcast the made-up word several times--and, at last, the first
breakthrough: the same sphere that had shushed the others repeated the
term back at the probe.

"The rain in Spain," said Rissa, grinning, "falls mainly on the plain."

"A thousand pardons," said Rhombus.  "My translator must be broken."

Rissa was still grinning.  "It's not broken.  It's just [hat I think
she's got it--I think we've made contact."

Keith gestured at the display.  "Which one is talking to US?"

Ropes danced on Rhombus's console.  'hat one," he said as a blue halo
appeared around one of the red circles.  He operated his console some
more.  "Here, let me give you a better picture.  Now that we've got the
green star for light, I can get good views of the individual darmats."

The red circle disappeared, replaced with a gray-on-black rendering of
the sphere.

"Can you increase the contrast?"  asked Keith.

"A pleasure to do so."  The parts of the sphere that had been gray or
smoky now showed in a much wider range of intensities, all the way
through to pure white.

Keith regarded it.  With the enhanced contrast, a pair of vertical white
convection lines were visible going from pole to pole, flaring out at
the equator.  "A cat's eye," he said.

Rissa nodded.  "It does look like one, doesn't it?"  She touched some
controls.  "Okay, Cat's Eye, let's see how intelligent you are."  A
horizontal black bar appeared floating in the holo bubble, about a meter
long and fifteen centimeters tall.  "That bar represents a series of
fusion lamps on the probe," said Rissa.  "The lamps have been turned off
since the probe was deployed.  Now, watch."  She tapped a key on her
console.  The black bar turned electric pink for three seconds, went
black again for three seconds, turned pink twice in rapid succession,
blacked out for another three seconds, then blinked on three times.

"When the bar is pink, I've got all the fusion lamps on," said Rissa.

"The probe is also broadcasting white radio noise when the lights are
on, and silence when they're off.  I've set the bridge speakers to the
frequency used by Cat's Eye."

The speakers were silent, but Keith could see indicators blinking on
Rhombus's panel, showing chatter on some of the other frequencies.

Rissa waited about half a minute, then touched a key.  The whole
sequence--one blink, two blinks, three blinks--repeated itself.

This time there was an immediate response: three darmat words, which
PHANTOM translated over the speakers as three distinctive patterns of
bleeps and bloops.

"Well," said Lianne, "if we're lucky, that's darmat talk for one, two,
three."

"Unless," said Tho;, "it's darmat for 'what the hell--?"" Rissa smiled,
and pushed the same key.  The probe winked out one, two, three again,
and Cat's Eye responded with the same three words.  "Okay," said Rissa.

"Now for the real test."  She pressed another key, and everyone watched
as the indicator bar winked in reverse sequence: three, two, one.

The darmat responded with three words.  Keith couldn't quite tell for
sure, but-- "Got it!"  crowed Rissa.  "Those were the same three words
Cat's Eye said before, but in the opposite order.  He understands what
we're saying--and therefore has at least a rudimentary intelligence."

Rissa ran the sequence again, and this time PHANTOM substituted the
English words "three, two, one," in a synthesized male voice with an
old-fashioned French accent--apparently that was to be the standard for
darmats.

The bridge staff was rapt as Rissa pressed on, learning the Darmat words
for the numerals four through one hundred.

Neither she nor PHANTOM could detect any kind of repeating pattern in
the word construction that would allow one to deduce the base the
darmats used for counting; it seemed that each numeral was represented
by a word unrelated to all the others.  She stopped at one hundred,
afraid the darmat would get bored by the game and cease communicating
with her at all.

Next came exercises in simple math: two blinks, a six-second
pause--double the normal length--two more blinks, another six-second
pause, and then four blinks.

Cat's Eye dutifully provided the words two, two, and four each of the
first five times Rissa repeated the sequence, but on the sixth, it
finally caught the intended meaning of the prolonged gaps: a six-second
gap meant a word was missing in the middle.  PHANTOM didn't wait for
Rissa's confirmation; when Cat's Eye next spoke, it translated the
darmat sentence as "two plus two equals four"--adding the terms for the
two operators to the translation database.  In short order, Rissa also
elicited the darmat words for "minus,"

"multiplied by,"

"divided by," "greater than," and "less

"I think," said Rissa, grinning from ear to ear, "that there's no doubt
that we're dealing with highly intelligent beings."

Keith shook his head in wonder as Rissa continued to use mathematics to
work out more vocabulary.  She soon had the darmat terms for "correct"
and "incorrect" (or "yes" and "no")--which she hoped would also be their
terms for "right" and "wrong" in other areas.  She then had Rhombus move
the probe in specific ways (carefully avoiding splashing the darmat with
hot ACS exhaust), and that led to the darmat words for "up," "down,"
"left," "right,"

"in front," "behind,"

"receding," "approaching," "turning," "tumbling," "circling," "fast,"

"slow," and more.

By moving the probe in a path right around Cat's Eye, Rissa was able to
get the darmat word for "orbit," and soon had picked up the words for
"star,"

"planet," and "moon," as well.

By using colored filters on the probe's fusion lamps, Rissa then
elicited the darmat words for various hues.  She next broadcast her
first simple original sentence, beginning with the arbitrary sign they'd
originally assigned to the probe that was Starplex's mouthpiece:
"Starplex moves toward green star."  Rissa then had Rhombus make the
probe do precisely that.

Cat's Eye understood at once, responding with the word for "correct."

He then sent his own sentence: "Cat's Eye moves away from Starplex,"
then turned word into deed.

Rissa replied with "correct."

When alpha shift was over, Keith went back to his apartment to shower
and eat, but Rissa kept on long into ship's night, building up a bigger
and bigger vocabulary.

Never once did Cat's Eye show the slightest sign of impatience or
fatigue.  By the time gamma shift was coming on duty, Rissa herself was
exhausted, and she turned the translation duties over to Hek.  They
worked for four days--sixteen shifts--slowly building up a darmat
vocabulary.

Cat's Eye never let his attention falter.  Finally, Rissa said, they
could engage in a simple conversation.  Keith, as director, would vet
the questions, but Rissa would actually pose them.

"Ask him how long he's been here," said Keith.

Rissa leaned into the microphone stalk emerging from her console.

"How long have you been here?"

The answer came quickly: "Since the time we started talking, times one
hundred times one hundred times one hundred times one hundred times one
hundred times one hundred."

PHANTOM's voice came on, interpolating: "That is approximately four
trillion days, or roughly ten billion years."

"Of course," said Rissa, "he could be speaking figuratively--just
meaning to convey a very long time."

"Ten billion years," said Jag, "is, however, a rough approximation of
the age of the universe."

"Well, if you were ten billion years old, I suppose you'd have a lot of
patience, too," said Thor, chuckling.

"Maybe ask him a different way," suggested Lianne.

"Is that how long all of you have been here?"  said Rissa into the mike.

"This group that duration," said the translated voice.

"This one, duration since the time we started talking, times one hundred
times one hundred times one hundred times fifty."

"That translates to approximately five hundred thousand years," said
PHANTOM.

"Perhaps he's saying this group of darmats is ten billion years old,"
said Rissa, "but he's only half a million himself."

"'Only,'" said Lianne.

"Now tell him how old we are," said Keith.

"You mean Starplex's age?"  asked Rissa.  "Or the age of the
Commonwealth?  Or the age of our species?"

"We're comparing civilizations, I guess," said Keith.  "So the
comparisons would be the oldest Commonwealth race."

He looked at his little hologram of Rhombus.  "That's the Ibs, who have
existed in their current species form for about a million years, right?"

Rhombus's web rippled in agreement.

Rissa nodded and keyed her mike.  "We duration since the time we started
talking times one hundred times one hundred times one hundred times one
hundred.  This one duration since the time we started talking times one
hundred plus one hundred."  She touched the off switch.  "I told him
that as a civilization, we're a million years old, but Starplex itself
is just two years old."

Cat's Eye replied by reiterating the number for its own personal age,
followed by the word for minus, then repeating the equation for
Starplex's tiny age, adding the word for "equals," and then reiterating
the same sequence it had used to express its own age.  "Very loosely,"
said Rissa, "I think he's saying that our age is nothing compared to
his."

"Well, he's right about that," said Keith, laughing.  "I wonder what it
would feel like to be that old?"

Chapter XV

Keith rarely entered any of the ship's Ibese areas.  Gravity was kept at
1.41 times Earth normal there (and 1.72 times ship's standard); Keith
felt as though he weighed 115 kilograms, instead of his usual 82.

He could stand it for short periods of time, but it wasn't pleasant.

The corridors here were much wider than elsewhere aboard Starplex, and
the interdeck areas were thicker, making for lower ceilings.  Keith
didn't have to stoop, but he found himself doing so anyway.  The air was
warm and dry.

Keith came to the room he was looking for, its door marked with a matrix
of yellow lights forming a rectangular shape with a small cimle just
below the rectangle's base at each end.  Keith had never seen a train
with wheels, except in a museum, but the pictogram did indeed look like
a boxcar.

Keith spoke into the air.  "Let her know I'm here, please, PHANTOM."

PHANTOM chirped acknowledgment, and a moment later, presumably having
received Boxcar's permission, the door slid aside.

Ib living quarters were unusual by human standards.  At first, they
seemed luxuriously big--the room Keith had entered measured eight by ten
meters.  But then one realized that they were actually the same size as
every other apartment aboard ship, but weren't divided into separate
sleeping, living, and bathing areas.  There were no chairs or couches,
of course.  Nor was there any carpeting; the floor was covered with a
hard robber material.  On their home-world, in preindustrial times, Ibs
built mounds of earth just wide enough so that they would fit between
their wheels--so that the frame and the other components could be
supported when the wheels temporarily separated from the body.

Boxcar had the manufactured equivalent of such a mound in one corner of
her room, but that was its only furnishing.

Keith found the art on the walls strange and disconcerting:
peanut-shaped images consisting of multiple, often distorted, views of
the same object from different angles superimposed one atop the other.

He couldn't make out what the ones on the far wall showed, but he was
startled to realize that the series of them nearest to him were studies
of severely premature human and Waldahud babies, with stubby limbs, and
strange, translucent heads.  Boxcar was a biologist, after all, and
alien life was probably fascinating to her, but the choice of subject
matter was unsettling to say the least.

Boxcar rolled toward Keith from the far side of the room.

It was nerve-racking to have an Ib approach from a good distance.  They
liked to accelerate to high speed and then stop with a jerk only a meter
or two away.  Keith had never heard of a human getting steamrollered by
one, but he was always afraid he'd be the first.

The Ib's lights flashed.  "Dr. Lansing," she said.  "An unexpected
pleasure.  Please, please--I have no seat to offer you, but I know the
gravity is too high.  Feel free to rest on my comfort mound."  A rope
flicked in the direction of the wedge-shaped construct at the side of
the room.

Keith's first thought was to reject the offer, but, dammit, it was
unpleasant standing under this gravity.  He walked over to the mound and
rested his rear on it.  'Thank you," he said.  He didn't know how to
begin, but he knew he would offend the Ib if he wasted time coming to
the point.  "Rissa asked me to come to see you.  She says you are going
to discorporate soon."

"Dear, sweet Rissa," said Boxcar.  "Her concern is touching."

Keith looked around the room, thinking.  "I want you to know," he said
at last, "that you don't have to go through with the discorporation--at
least so long as you are aboard Starplex.  All staff aboard this ship
are considered de facto embassy personnel; I can try to arrange immunity
for you."

He looked at the being; he wished it had a face--wished it had normal
eyes, eyes that he could try to read.  "Your service has been exemplary;
there's no reason why you couldn't continue to serve aboard Starplex for
the rest of your natural life."

"You are kind, Dr. Lansing.  Very kind.  But I  must be true to myself.

Understand that though I have not mentioned my impending discorporation
to anyone, I have been preparing mentally and physically for it for
centuries now.  I have timed the events of my life to conclude now; I
wouldn't know what to do with the extra fifty years."

"You could continue your research.  Who knows?  With another half
century of work on the senescence problem, you might lick it.  You might
never have to die."

"An eternity of shame, Dr.  Lansing?  An eternity of guilt?

No, thank you.  I am unalterably committed to my stated course of
action."

Keith was quiet for a moment, thinking.  Arguments and counterarguments
ran through his head; new tacks, new approaches.  But he dismissed them
all.  It wasn't his business, wasn't his place.  Finally, he nodded.

"Is there anything I can do to make it easier for you?  Any special
facilities or equipment you need?"

"There is a ceremony.  Normally, most Ibs would not attend; to do so
would be to have the guilty party end up wasting even more of their
time.  I imagine that only my closest Ib friends will come.  So, on that
basis, I have no need for a large venue.  But, since you have offered, I
would request, if possible, that I be allowed to use one of the docking
bays for the ceremony--and that once the ceremony is completed, my
component parts be ejected into space."

"If that is what you'd like, then of course you have my permission."

"Thank you, Dr.  Lansing.  Thank you very much."

Keith nodded, and headed for the door.  He made his way down the warm
corridor, back into the CAGE conditions of the central shaft.

Normally, when he exited an Ibese area into the lower gravity of the
rest of the ship, he felt buoyant, light as a feather.

But not this time.

"Tachyon pulse!"  announced Rhombus from the ExOps station.  "Something
coming through the shortcut.  Small object, only about a meter in
diameter."

Most likely a watson, Keith thought.  "Let's have a look at it,
Rhombus."  Part of the spherical hologram was set off by a blue border,
and inside the border was a telescopic view of the object that had
popped out of the shortcut.

"Welcome home!"  said Thor Magnor, grinning broadly.

"Somebody better get Hek and Shanu Azmi down here," said Keith.

"Will do," said Lianne, then a moment later, "They're on their way."

The port starfield split and the Waldahud alien-communications
specialist waddled onto the bridge.  Almost simultaneously, the door
behind the seating gallery opened up, and Shahinshah Azmi came in.  He
was wearing tennis shorts and holding a racket.  Keith gestured at the
magnified image.  "Look what's come back," he said.

All four of Hek's eyes went wide.  "That's .  . . that's wonderful!"

"Rhombus," Keith said, "scan it for anything untoward.  If it's clean,
use a tractor beam to haul it into docking bay six."

"Scanning .  . . no obvious problems.  Locking on tractor beam."

"Keep it isolated inside a forcefield once you get it aboard."

"Will do, with respect."

"I wish it had arrived last week," said Azmi.

"Why?"  Rissa asked.

"It would have saved us all the work of building it."

Rissa laughed.

"Shanu, Hek, shall we repair to bay six?"  Keith said.

"I'd like to have a look, too," said Rissa.

Keith smiled.  "By all means."

The four made their way to the docking bay.  There, they stood behind a
forcefield curtain, Hek about two meters to Keith's right, Azmi just
behind him, and Rissa so close to her husband's left side that their
elbows lightly touched.  The cube was maneuvered into the bay by a
series of invisible beams.  Once it was set down, a force bubble was
erected around it, and the space door slid down from the ceiling.

They waited until the bay was pressurized, then went out to look at the
cube.

It had weathered the eons well.  Its surface looked like it had been
scoured with steel wool, but all the incised markings showing the sample
questions on top were quite legible.  It turned out that Rhombus had
maneuvered the cube in so that the face with the answer was the one the
cube was sitting on.

"PHANTOM," Keith said, "flip the cube a quarter turn so that the bottom
face is visible."

Tractor beams manipulated the time capsule.  In the space that had been
left for the answer, black symbols stood out against a white background
that had somehow been fused to the cube's surface.

"Gods," said Hek.

Rissa's jaw dropped.

Keith stood immobile.

At the top of the' answer space was a string of Arabic numerals:

10-646-397-281

And beneath it, in English, was: "Pushing back the stars is necessary,
and not a threat.  It will benefit us all.  Don't be afraid."

Underneath all that, in somewhat smaller type, it said, "Keith Lansing."

"I don't believe this," Keith said.

"Hey, look at this," barked Hek, leaning closer.  "That isn't how one
makes that character, is it?"

Keith peered at it.  The serif on each lowercase u was on the left side
of the letter instead of the right.  "And the apostrophe in 'don't' is
backward, too," said Keith.

"And what's that series of numbers at the top?  asked Pdssa.

"It looks like a citizenship number," Keith said.

"No--a mathematical expression," said Hek.  "It is--it is--Central
Computer?"

"Negative one thousand three hundred and fourteen," said PHANTOM's
voice.

"No, it's not that," said Rissa, shaking her head slowly.

"When humans write a letter, that's where they put the date."

"So what's the format?"  asked Hek.  "Hour, then day, then month, then
year?  That doesn't work.  How about the other way around?  The tenth
year, the six hundred and forty-sixth day.  That makes no sense either,
since they're only four hundred or so days in a Terran year."

"No," said Rissa.  "No, it's not that.  It's the year--the whole thing
is the year.  Ten billion, six hundred and forty-six million, three
hundred and ninety-seven thousand,

two hundred and eighty-one."

"The year?"  said Hek.

"The year," said Rissa.  "The Earth year.  Anno Domini--after the birth
of Christ, a prophet."

"But I've seen lots of human numbering before," said Hek.

"Yes, you separate big numbers into thousands groups--my people do it
into ten thousands.  But I thought you used--what do you call
them?--those subscripted curlicuesT'

"Commas," said Rissa.  'Ze do use commas, or spaces."

She seemed to be having trouble keeping her balance; she moved over to
the docking-bay wall and leaned against it.

"But .  . . but imagine a time so far in the future that English isn't
used anymore .  . . a time in which it's been millions or billions of
years since--" she pointed at Keith-- "since anyone has used English.

They might indeed misremember the convention for writing big numbers, or
how to make an apostrophe, or where the little extra doodad on a u
went."

"It's got to be a fake," Keith said, shaking his head.

"If it is, it's a perfect one," said Azmi, waving a hand scanner.  "We
built some very long half-life radioactives into the cube's
construction.  The cube is now ten billion Earth years old plus or minus
nine hundred million.  The only way to fake that kind of dating would be
to manufacture a counterfeit cube using the correct ratio of isotopes to
give that apparent age.  But even to the smallest detail this one
matches our original--except for the radioactive decay and the surface
scouring."

"But to have it signed with my name," said Keith.  "Surely that's a
mistake?"

"Perhaps somehow your name has come to be associated with Starplex,"
said Hek.  "You are its first director, after all, and, frankly, we
Waldahudin always thought you took too much of the credit.  Maybe that
was not a signature.  Maybe it was the address, or the salutation, or--"

"No," said Rissa, eyes growing wide.  Her voice was shaking with
excitement.  "No--it's from you."

"But .  . . but that's crazy," Keith said.  "There's no way I'm going to
be alive ten billion years from now."

"Unless it's a relativistic effect," said Hek, "or perhaps suspended
animation."

"Or .  . ."  said Rissa, her voice still shaking.

Keith looked at her.  "Yes?"

She started jogging out of the bay.

"Where are you going?"  barked Hek.

"To find Boxcar," she shouted.  "I want to tell her that our
life-prolongation experiments are going to succeed beyond our wildest
dreams."

**ZETA DRACONIS**

Glass rose from the clover-covered ground.  "Perhaps you need some time
to rest," he said.  "I'll be back in a little while."

"Wait," said Keith.  "I want to know who you are.  Who you really are."

Glass said nothing, his head inclined to one side.

Keith got to his feet as well.  "I've got a right to know.  I've
answered every one of your questions.  Now, please, answer this one of
mine."

"Very well, Keith."  Glass spread his arms.  "I'm you--Gilbert Keith
Lansing--but you of the future.  You don't know how long I'd been
racking my brain trying to remember what the bloody G stood for."

Keith's jaw had dropped.  "That--that can't be right.  You can't be me."

"Oh, yes I am," said Glass.  "Of course, I'm a little bit older."  He
touched the side of his smooth, transparent head, then made the
wind-chime laughter sound.  "See?  I've lost all my hair."

Keith narrowed his eyes.  "How far in the future are you from?"

"Well," said Glass, gently, "actually, you've got it backward.  We are
in my present.  The appropriate question is, how far from the past are
you from?"

Keith felt himself losing his balance.  "You mean--you mean this isn't
2094?"

"Twenty-ninety-four what?"

"The Earth year 2094--2094 n.o. Two thousand and ninety-four years after
the birth of Christ."

"Who ?  Oh, wait--my reckoner just reminded me.  Let me work it out; I
know the current year in absolute counting from the creation of the
universe, but .  . . ah, okay.  In your system, this is the year ten
billion, six hundred and forty-six million, three hundred and
ninety-seven thousand, two hundred and eighty-one."

Keith staggered back a half pace.  "You sent back our time capsule."

"That's right."

"How--how did I get here?"

"When your pod passed through the shortcut, I locked you into stasis.

Time passed in the universe, but not for you.

When it got to be this year, I unlocked you.  Don't worry, though.  I
intend to put you back where you came from."  A pause.  "Remember that
pink nebula you saw as you came out of the gate?  That's what's left of
what used to be Sol."

Keith 's eyes went wide.

"Don't be concerned," said Glass.  "No one was injured when Sol went
nova.  It was all carefully engineered.  See, that type of star doesn't
naturally go nova; it just decays to a white dwarf.  But we like to
recycle.  We blew it up so that its metals would enrich the interstellar
medium."

Keith felt dizzy.  "And how--how are you going to return me to my time?"

"Through the shortcut, of course.  Time travel to the past works well;
we just can't do it to thefuture--that's why we had to let you come
forward in stasis through ten billion years.  Ironically, it turns out
that it's forward time travel, not backward travel, that results in
unsolvable paradoxes, making it impossible.  We'll send you back to the
moment you left.  You don't have to worry about your friends missing
you; no matter how many hours you generously stay with us, we'll get you
to Tau Ceti at the time you're expected."

"This is incredible."

Glass shrugged.  "It's science."

"It's magic," said Keith.

Glass shrugged again.  "Same thing."

"But--but--if you're really me, if you're really from

Earth, then why did you screw up on the simulation?"

"Pardon?"

"The Earth simulation.  It has errors in it.  Fields full of four-leaf
clover, something only ever found as the occasional mutant, and birds
that I've never seen before."

"Oh."  The wind-chime sound.  "My mistake.  I took the simulation from
some ancient recordings we had, but I was probably a bit sloppy.  Let me
just check with my reckoner .  . . yup, my fault.  It is a perfect
simulation of Earth, but of Earth about one-point-two million years
after you were born.  The things that were out of place were species
that hadn't yet evolved in your time.  Come to think of it, you wouldn't
have recognized the constellations, either, if I'd ever let it become
nighttime."

"My God," said Keith.  "I hadn't even begun to think about evolution.

If you're ten billion years older than me, then--then you're older than
any form of life on Earth in my time."

Glass nodded.  "By your time, life had been evolving on Earth for four
billion years.  But there are Earth-descended life-forms in this time
that are products of fourteen billion years of evolution.  You'll never
believe what daisies evolved into--or sea anemones, or the bacteria that
caused whooping cough.  In fact, I had lunch a few days ago with someone
who evolved from whooping-cough bacteria."

"You're kidding."

"No, I'm not."

"But it's incredible .  . ."

"No.  It's just time.  Lots and lots of time."

"What about humans?  Did humans continue to breed, to have children?

Or did that stop when--when life prolongation was discovered?"

"No, humanity continues to evolve and change.  New humans--those who've
been evolving for the last ten billion years--don't mix much with old
humans like me.

They're .  . . quite different."

"But if you're me, how did you change?  I mean, your body is
see-through."

Glass shrugged.  "Technology.  Flesh and blood tends to wear out; this
is better.  In fact, I can reconfigure myself any way I want.

Transparent is in style right now, but !  think the hint of aquamarine
is quite classy, don't you?"

Chapter XVI

Rissa, Hek, and the rest of the alien-communications team continued to
exchange messages with the darmat they'd dubbed Cat's Eye.  The
conversation became increasingly fluid as new words were added to the
translation database, or old words had their meanings refined.  When
Keith next came onto the bridge, Rissa was in the middle of an
apparently philosophic conversation with the giant being.

The usual alpha-shift crew was on duty, except that the ExOps station
was vacant: Rhombus was off doing something else, and his position had
been slaved to a dolphin floating in the open pool on the starboard side
of the bridge.

"We have been unaware of your existence," Rissa said into the microphone
stalk rising from her console.  "We knew a large amount of invisible
matter was out there, because of the gravitational effects, but we
didn't know it was alive."

"Two types of substance," replied the darmat in that French accent
PHANTOM had assigned to him.

"Yes," said Rissa.  She looked up and waved a greeting at Keith as he
took his seat next to her.

"Not react sharply," said the Cat's Eye.  "Only gravity the same."

"That's correct," said Rissa.  The all-encompassing hologram showed an
enhanced view of Cat's Eye in front of the cluster of workstations.

"Most like us," said the darmat.

"The vast majority of all matter is like you, yes," replied Rissa.

"Ignore you."

"You've ignored us?"

"Insignificant."

"Were you aware that part of our type of substance was alive?"

"No.  Not occur to look for life on planets.  So small you are."

"We.  wish to have a relationship with you," said Rissa.

"Relationship?"

"For mutual benefit.  One plus one equals two.  You plus us equals more
than two."

"Understand.  More than the sum of the parts."

Rissa smiled.  "Exactly."

"Relationship sensible."

"Do you have a word for those with whom you have mutually beneficial
relationships?"

"Friends," said the darmat, PHANTOM translating the word the first time
it had been received.  "We call them friends."

"We are friends," said Rissa.

"Yes."

"The kind of material you're made out of--the material we call dark
matter--is all of it alive?"

"No.  Only tiny fraction."

"But you say there has been living dark matter for a very long time?"

"Since the beginning."

"Beginning of what?"

"Of--all the stars combined."

"Of the totality of everything?  We call that the universe."

"Since the beginning of the universe."

"That's an interesting point right there," said Jag, sitting on Keith's
left.  "The idea that the universe had a beginning--it did, of course,
but how does it know that?

Ask it about that."

"What was the universe like in the beginning?"  said Rissa into the
mike.

"Compressed," said the darmat.  "Small beyond small.

One place, no time."

"The primordial atom," said Jag.  "Fascinating.  It's right, but I
wonder how such a creature would deduce that?"

"They communicate by radio," said Lianne, turning around at InOps to
face Jag.  "They probably reasoned it out the same way we did: from the
cosmic microwave background and the redshifting of radio noise from
distant galaxies'."

Jag grunted.

Rissa continued her dialogue: "You have told us that neither you
personally, Cat's Eye, nor this group of darmats is anywhere near that
old.  How do you know that darmat life existed all the way back to the
beginning."

"Had to," replied the darmat.

Jag barked dismissively.  "Philosophy," he said.  "Not science.  They
just want to believe that."

"We have not existed nearly that long," said Rissa into the microphone
stalk.  "We have not found any evidence for life of any type made out of
our kind of matter that is more than four billion years old."

pHANTOM converted the time expression into something the darmat could
understand.

"As said earlier, you are insignificant."

Jag barked at PHANTOM.  "Query: How was the translation for
'insignificant' derived?"

"Mathematically," said the computer in the appropriate language into
each individual's earpiece.  "We established that the difference between
3.7 and 4.0 was 'significant,' but that the difference between 3.99 and
4.00 was 'insignificant.""

Jag looked at Rissa.  "So in this context the word might convey a
different sense.  It might mean something meta-phoricai--a 'late
arrival' could be equated with insignificance, for instance."

Thor looked over his shoulder at the Waldahud and grinned.  "Don't like
the idea of being dismissed out of hand, eh?"

"Don't be abrasive, human.  It's simply that we have to be careful when
generalizing the use of alien words.  And besides, perhaps he's
referring to the signaling probe.  At less than five meters in length,
it could indeed be termed insignificant."

Rissa nodded and spoke into the mike.  "When you say we are
insignificant, are you referring to our sze.

"Not size of speaking part.  Not size of part that ejected speaking
part."

"So much for outsmarting him," said Thor, grinning.  "He knows that the
signaling probe came from this ship."

Rissa covered the mike with her hand; the gesture was as good a signal
as any to PHANTOM to temporarily halt transmission.  "It doesn't matter,
I guess."  She removed her hand and spoke again to Cat's Eye.

"Are we insignificant because we haven't been around as long as you
have?"

"Not a question of time length; a question of time absolute.  We here
from beginning; you not.  By definition, we significant, you not.

Obviously so."

"I don't know about that," said Keith, good-naturedly.

"The good guys are never first, only better."

Rissa covered the mike and looked at him.  "Regardless, I think we
should steer clear of philosophy until we're more comfortable with each
other.  I don't want to accidentally give offense and cause him to clam
up."

Keith nodded.

Rissa spoke into the mike again.  "Presumably there are other
communities of darmats."

"Billions of communities."

"Do you interact with them?"

"Your radio signals are not powerful, and are close to the frequency of
the microwave background radiation.  They would not be perceptible over
a great distance."

"Then how do you interact with other darmat communities?"

"Radio-one only for local talk.  Radio-two for communication between
communities."

Lianne turned to Rissa.  "Is he saying what I think he's saying?  That
the darmats are natural transmitters of hyperspace radio?"

"Let's find out," said Rissa: She faced the mike again.

"Radio-one travels at the same speed as light, correct?"

"Yes."

"Radio-two travels faster than light, correct?"

"Yes."

"Jesus," said Keith.  "If they use hyperspace radio, how come we've
never encountered their signals before?"

"There are an infinite number of quantized hyperspace levels," said
Lianne.  "None of the Commonwealth races has had hyperspace radio for
more than fifty years, and the whole Commonwealth uses only about eight
thousand quantized levels; it's quite possible that we've never happened
to key into one of the ones the darmats use."  She turned her gaze to
Rissa.  "The way we do hyperspace radio requires an enormous amount of
energy.  It would be well worth pursuing this topic.  They may have a
method of doing it that takes a lot less power."

Rissa nodded.  "We use a kind of radio-two, as well.  Will you tell us
more about how yours works?"

"Tell all," replied Cat's Eye.  "But little to tell.  We think one way,
thought is private.  We think another way, thought is transmitted on
radio-one.  We think a third, harder way, and thought is transmitted on
radio-two."

Keith laughed.  "It's like asking a human to explain how speech works.

We just do it, that's all.  It's--"

"Forgive me for interrupting, Dr. Lansing," said PHAN TOM, "but you
asked me to remind you and Dr.  Cervantes of your 14:00 appointment."

Keith's face fell.

"Damn," he said.  "Damn."  He turned to Rissa.  "It's time."

She nodded.  "PHANTOM, please get Hek down here to continue the dialogue
with Cat's Eye."

As soon as Hek had arrived, they both rose from their chairs and left
the room.

Keith and Rissa exited from the elevator and walked the short distance
to the oversized black door with the giant fluorescent orange "20"
painted on it.  The locking bolts pulled aside.  The noise they made had
always been faintly familiar to Keith, but this time he finally placed
it: it was just like the sound of a rifle being cocked in an old-time
western movie.

Most doors aboard ship split down the middle with the two panels moving
into pockets on either side, but' this heavy one slid as one piece to
the left--safety demanded there be no seams or weak points in the seal.

Rissa gasped.  Keith felt his jaw go slack.

There were well over a hundred Ibs in the docking bay, lined up in neat
rows--like a parking lot filled with wheelchairs.  "PHANTOM, how many
are there?"  Keith said softly.

"Two hundred and nine, sir," replied the computer.  "The entire ship's
complement of Integrated Bioentities."

Rissa shook her head slightly.  "She said only her closest friends would
attend."

"Well," said Keith, stepping into the room, "Boxcar is very personable.

I guess all the Ibs aboard consider her a close friend."

There were six other humans present, all members of Rissa's
life-sciences staff.  There was also one lone Waldahud, whom Keith
couldn't quite place.  Keith glanced at his watch: 13:59:47.  No doubt
whatever was going to happen would begin on time.

"Thank you all for coming," said Boxcar's voice, over

Keith's implant.  It was easy to spot her: hers was the only web
flashing.  It was eerie, in a way.  PHANTOM's translation was piped into
his left acoustic nerve; the other ear heard nothing--even a room this
size full of raucous Ibs would be dead silent.

Boxcar was fifteen meters from where Keith and 'Rissa were standing.

In front of the plated space door, PHANTOM was projecting a giant
hologram of Boxcar, so that all the Ibs could see her flashing web.

Something strange, there: The strands of her web were bright green.

Keith had never seen any Ib's web that color before.

He turned to Rissa, but she must have guessed his question.  "It
represents a deeply emotional state," she said.

"Boxcar is choked up over the show of support from her people."

Boxcar's web flashed again.  The translation said, "The whole and the
parts--of one, and of them all.  The gestalt has resonances on the macro
scale and the micro.  It binds."

Obviously, Boxcar was addressing her fellow Ibs.  Keith thought he got
the gist of what she was saying--something about being part of the Ib
community having meant as much to her as being a community of parts
herself.  Keith prided himself on his acceptance of aliens, his run-ins
with Jag notwithstanding.  But this was all a little too surreal for
him; he knew he was about to watch someone die, but the emotions he
should be feeling hadn't yet come to the surface.  Rissa, on the other
hand, had that look she got when trying not to cry.  She and Boxcar had
been closer than he'd known, Keith realized.

"The road is clear," concluded Boxcar.  She rolled several dozen meters
away from the others, out into the center of the bay.

"Why's she doing that?"  whispered Keith.

Rissa shrugged her shoulders, but PHANTOM replied into both of their
implants: "During discorporation, components-especially wheels--may
panic, and seek to bond with any other Ib in the area.  It is customary
to move far enough away so that if such a thing is attempted, there's
plenty of time to react."

Keith nodded slightly.

And then it began.  In the middle of the bay was a standard Ib comfort
mound.  Boxcar rolled over it so that the hump supported her frame from
underneath.  Her web--visible in PHANTOM's giant hologram--turned an
almost electric purple, another color Keith had never seen before.  The
light points at the web's countless intersections grew brighter and
brighter, a dense constellation map with every star a nova.

Then, one by one, the lights winked out.  It took perhaps two minutes
for them all to go dark.

Boxcar's frame tipped forward, and her web slid off to the bay floor,
landing in a loose pile.  Keith had thought the web was already dead,
but it arched up sharply, as if a fist were pushing it up from
underneath.  The strands had now lost all their color; they looked like
thick nylon fishing line.

After a moment, though, the web finally did expire, collapsing into a
heap.  Boxcar was now blind and deaf (she had once had a magnetic sense,
too, but that had been neutralized through nanosurgery when she'd left
her home-world; it caused severe disorientation aboard spaceships).

Next, Boxcar's wheels disengaged from the axles on the frame.  Wheel
disengaging wasn't unusual in and of itself.

The system that allowed nutrients to pass from the axle into each wheel
didn't provide enough food for the wheels, and in their native
environment they would periodically separate from the rest of the
gestalt for feeding.  Thick tendrils, similar to the Ib's bundle of
manipulatory ropes, popped out of the sides of the wheels, preventing
them from falling over (or righting them if they did).

Almost immediately after it separated, the left wheel tried to rejoin
the frame.  Just as PHANTOM said it might, it panicked when it realized
that little bumps had risen up all around the axle's circumference,
preventing it from reconnecting.

It rolled around the bay, the grabbing projections around its rim
extending and retracting at a great rate.  The wheel had a few vision
sensors of its own, and as soon as it caught sight of the huge
collection of Ibs, it made a beeline for the closest.  That Ib spun
away, avoiding the wheel.  One of the others--Butterfly, Keith assumed,
the one Ib doctor on board--surged forward, a manipulatory rope
extended, a silver-and-black medical stunner held at its tip.  The
stunner touched the wheel, and it stopped moving.  It stood for several
seconds, then the rootlike appendages coming out of its sides seemed to
go soft, and the wheel toppled onto its side.

Keith turned his attention back to the center of the bay.

Boxcar's bundle of ropes had slid to the floor, near the discarded
sensor web.  They were reaching up to the frame and disengaging the blue
pump from the central green pod, and gently lifting the pump to the
floor.  Keith could see the pump's large central breathing orifice
cycling through its usual four-step sequence of open, stretch, compress,
and close.  After about forty seconds, though, the sequence started to
get distorted as the pump seemed to lose track of what it was doing. The
orifice movements became jumbled--opening, then immediately compressing;
trying to stretch wide after closing.  There was a small gasping
sound--the only sound in the entire bay.  Finally the pump stopped
moving.

All that was left was the pod, sitting on the saddle-shaped frame.

Keith whispered to Rissa: "How long can the pod survive without the
pump?"

Rissa turned to him, her eyes wet.  She blinked several times,
dislodging tears.  "A minute," she said at last.  "Perhaps two."

Keith reached over and squeezed her hand.

Everything was still for about three minutes.  The pod expired quietly,
without movement or sound--although somehow, apparently, the Ibs knew
when it was gone, and, as one, they began to roll out of the bay.  All
their webs were dark; not a word was passing between them.  Keith and
Rissa were the last to leave.  Butterfly would return shortly, Keith
knew, to take care of jettisoning Boxcar's remains into space.

As they walked out of the bay, Keith thought about his own future.  He
was going to live a long, long time, apparently.  He wondered whether
billions of years from now he'd be able to escape the mistakes of his
own past.

They couldn't sleep that night, of course.  Boxcar's death had upset
Rissa, and Keith was wrestling with his own demons.  They lay side by
side in their bed, wide-awake, Rissa staring at the dark ceiling, Keith
looking at the faint red spot on the wall made by the light seeping
around the plastic card he used to cover his clock face.

Rissa spoke--just one word.  "If .  . ."

Keith rolled onto his back.  "Pardon?"

She was quiet for a time.  Keith was about to prod her again, when she
said, very softly, "If you don't remember how to make a u or an
apostrophe, will you remember me--remember us?"  She rolled over, looked
at him.  "You're going to live another ten billion years.  I can't begin
to comprehend that."

"It's .  . . mind-numbing," said Keith, shaking his head against the
pillow.  He, too, was quiet for a time.  Then: "People always fantasize
about living forever.  Somehow, 'forever' seems less daunting than
putting a specific date on it.  I could deal with immortality, but
contemplating the specific notion of being alive ten billion years from
now .  . .

I just can't make sense of it."

"Ten billion years," said Rissa again, shaking her head.

"Earth's sun will long be dead, Earth will be dead."  A beat.

"I will be dead."

"Maybe.  Maybe not.  If it is life prolongation, then surely it's
because of your studies here on Starplex.  After all, why else would I
have ended up as one of the recipients of the process?  Maybe we're both
alive ten billion years from now."

More silence.

"And together?"  said Rissa, at last.

Keith exhaled noisily.  "I don't know.  I can't imagine any of it."  He
sensed he was saying the wrong thing.  "But .  . .

but if I'm to face that much of a future, I would want it to be with
you."

"Would you?"  said Rissa, at once.  "Would we have anything left to
explore, to learn about each other, after all that time?"

"Maybe .  . . maybe it's not corporeal existence," said Keith.  "Maybe
my consciousness is transferred into a machine.  Wasn't there a cult on
New New York .that wanted to do that--copy human brains into computers?

Or maybe .  . . maybe all of humanity becomes one giant mind, but the
individual psyches can still be tapped.  That would be--"

"Would be less frightening that the concept of personally living another
ten billion years.  In case you haven't done the math yet, that would
mean that so far, you've only lived one two-hundred-millionth of the age
you're going to become."

She paused and sighed.

"What?"  asked Keith.

"Nothing."

"No, you're upset about something."

Rissa was quiet for about ten seconds.  "Well, it's just that your
current midlife crisis has been hard enough to live with.  I'd hate to
see what kind of stunts you're going to pull when you turn five
billion."

Keith didn't know what to say.  Finally, he settled on a laugh.  It
sounded hollow to him, forced.

Quiet again--long enough that he thought perhaps she'd .  at last fallen
asleep.  But he couldn't sleep himself.  Not yet, not with these
thoughts going through his head.

"Dulcinea?"  he whispered softly--so softly that if she were already
asleep he hopefully wouldn't wake her.

Keith swallowed.  Maybe he should leave the issue alone, but .  . .

"Our anniversary is coming up."

"Next week," said the voice in the darkness.

"Yes," said Keith.  "It'll be twenty years, and--"

"Twenty wonderful years, honey.  You're always supposed to include the
adjective."

Another forced laugh.  "Sorry, you're right.  Twenty wonderful years."

He paused.  "I know that we're planning to renew our wedding vows that
day."

A small edge to Rissa's voice.  "Yes?"

"Nothing.  No, forget I said anything.  It has been a wonderful twenty
years, hasn't it?"

Keith could just make out her face in the darkness.  She nodded, then
looked at him, meeting his eyes, trying to see beyond them, see the
truth, see what was bothering him.

And then it came to her, and she rolled onto her side, facing away from
him.  "It's okay," she said at last.

"What is?"

And she spoke the final words that passed between them that night.

"It's okay," she said, "if you don't want to say, 'for as long as we
both shall live.""

Keith sat at his workstation on the bridge.  Holograms of three humans
and a dolphin hovered above the station's rim.

In his peripheral vision, he was aware of one of the bridge doors
opening and Jag waddling in.  The Waldahud didn't go to his own
workstation, though.  Instead he stood in front of Keith's and waited,
in what seemed a state of some agitation, while Keith finished the
conference he was conducting with the holographic heads.  When they'd
logged off, Keith looked up at Jag.

"As you know, the darmats have been moving," said Jag.

"I'm frankly surprised at their agility.  They seem to work together,
each sphere playing off its own gravitational and repulsive forces
against the others to move the whole community cooperatively.  Anyway,
in doing so, they've completely reconfigured themselves, so that
individual darmats that we couldn't clearly observe before are now at
the periphery of the assemblage.  I've made some predictions about which
darmat might next reproduce, and I'd like to test my theory.  For that,
I want you to move Starplex to the far side of the dark-matter field."

"PHANTOM, schematic local space," said Keith.

A holographic representation appeared in midair between Keith and Jag.

The darmats had moved around to the opposite side of the green star, so
that Starplex, the shortcut, the star, and the darmat community were
pretty much arranged in a straight line.

"If we move to the far side of the darmat field, we'll be out Of view of
the shortcut," said Keith.  "We might miss seeing a watson come through.

Can't you just put a probe there?"

"My prediction is based on very minute mass concentrations.

I need to use either our deck-one or deck-seventy hyperscope to make my
observations."

Keith considered.  "All right."  He tapped a key on his console and the
usual holograms of Thor and Rhombus popped into being.  "Rhombus, please
check with everyone who is currently doing external scanning.

Find out when the soonest we can move the ship without interrupting
their work will be.  Thor, at that time take us to the opposite side of
the dark-matter field, positioning us at coordinates Jag will supply you
with."

"Serving is the greatest pleasure," said Rhombus.

"Bob's your uncle," said Thor.

Jag moved his head up and down, imitating the human gesture.

Waldahudin never said thank you, but Keith thought the pig looked
inordinately pleased.

Chapter XVII

The bridge was calm, the six workstations floating serenely against the
holographic night.  It was 0500 ship's time; delta shift was in the
final hour of its watch.

In the director's position was an Ib named Wineglass; other Ibs were at
the Internal-Ops and Helm stations.

Physical sciences was slaved to a dolphin named Melon-dent, a Waldahud
was at life sciences, and a human named Denna Van Hausen was at External
Ops.

A grid of force screens radiated down from the invisible ceiling,
creating millimeter-wide vacuum gaps between each workstation,
preventing transmission of noise between them.  The Ib at Internal Ops
was engaged in a holographic conference with three miniature floating
Ibs and three disembodied Waldahud heads.  The human at External was
reading a novel on one of her monitor screens.

Suddenly, the silencing force fields snapped off and an alarm began to
sound.  "Unidentified ship approaching," announced PHANTOM.

"T'here!"  said Van Hausen, pointing to the image of the nearby star.

"It's just passing from behind the photosphere."

PHANTOM was showing the unknown ship as a small red triangle; the actual
vessel was far too small to be visible at this distance.

"Any chance that it's just a watson?"  asked Wineglass, his British
accent carrying a hint of Cockney.

"None," said Van Hausen.  "It's at least as big as one of our
probeships."

Lights moved across Wineglass's web.  "Let's get a look at it," he said.

The Ib at the helm station rotated the ship slightly so that the
deck-seventy optical array was aimed at the 'intruder.  A square frame
appeared around part of the star, and within it a magnified view
appeared.  The approaching ship was illuminated on one side by the green
star.  The other side was a black silhouette, visible only because it
eclipsed the background stars.

Wineglass spoke to Kreet, the Waldahud on his right.  'What looks like a
Waldahud design.  The central engine pod, no?"

Waldahudin believed each ship--or building or vehicle--should be unique;
they did not mass-produce from the same design.  Kreet lifted all four
of his shoulders.  "Maybe," be said.

"Any transponder signal, Denna?"  asked Wineglass.

"If there is one," the human said, "it's lost in the noise from the
star."

"Please try to contact the ship."

"Transmitting," said Denna.  "But they're still over fifty million
klicks away; it'll take almost six minutes for any reply, and--God!"

A second ship was coming around the limb of the green star.  It was
similar in size to the first, but had a different, more blocky design.

Still, the trademark Waldahud central engine pod was visible.

"Better get Keith down here," said Wineglass.

Lights rippled across the Ib at InOps.  "Director Lansing to the
bridge!"

"Fry to contact the second ship, too," Wineglass said.

"Doing so," said Van Hausen..  "And--Jesus, I'll try to contact that
third one, as well."  Another ship, half emerald fire glinting off
polished metal, half black nothingness, was emerging from behind the
star.  A moment later a fourth and then a fifth appeared.

"It's a bloody armada," said Van Hausen.

"They Waldahud ships clearly are," said Melondent from his open pool to
the left of the physics workstation.

"Thruster exhaust signatures most characteristic."

"But what would five--six, eight--eight Waldahud craft want here?"

asked Wineglass.  "Denna, where are they heading?"

"They're doing parabolic paths around the star," the human woman said.

"Hard to say exactly where they're planning to end up, but Starplex's
current position is within eight degrees of the most likely projected
course."

"They after us are coming," said Melondent.  "We should--"

A door appeared in the hologram.  Keith Lansing strode onto the bridge,
unshaven, hair matted down from sleep.

"Sorry to wake you early," said Wineglass, rolling away from the
director's workstation, "but we have company."

Keith nodded at the Ib, and waited for a pOlychair to emerge from the
trapdoor in front of his console.  It was already morphing into human
configuration as it rose up from the floor.  Keith seated himself.

"You've tried contacting them?"

"Yes," said Denna.  "Earliest possible response is in forty-eight
seconds, though."

"They're Waldahud ships, aren't they?"  said Keith, his workstation
rising to the height he preferred.

"Very likely so," said Wineglass, "although, of course, Waldahud ships
are sold all over the Commonwealth.  They could be crewed by somebody
else."

Keith rubbed sleep from his eyes.  "How did so many ships arrive without
our knowing it?"

"They must have emerged one at a time from the shortcut while it was
shielded from our view by the green star," Wineglass said.

"Christ, of course," said Keith.  He consulted the readout of who was
operating which station.  "Double-Dot, get Jag down here."

The Ib at Internal Ops slapped his control panel with ropes, then, a
moment later, said, "Jag has his communications routed to a voice
mailbox.  It's his normal sleep period."

"Override," said Keith.  "Get him down here right now.

Denna, any reply to our messages?"

"Nothing."

Keith glanced up at the glowing digital clocks floating against the
starfield.  "It's almost shift change anyway," he said.  "Let's get the
full alpha-shift staff down here."

"Alpha shift, report immediately to the bridge," said Double-Dot.

"Lianne Karendaughter, Thoraid Magnor, Rhombus, Jag, and Clatissa
Cervantes to the bridge, please."

"Thank you," said Keith.  "Denna, open a channel to all the approaching
ships."

"This is G. K. Lansing, Director of the Commonwealth research vessel
Starplex.  State your business, please."

"Transmitting," said Denna.  "They've closed the distance between us and
them considerably.  If they care to respond to your latest message, we
should have an answer in under three minutes."

A door opened up in the part of the hologram displaying the framed
close-up of the approaching craft.  Jag walked through, his fur not yet
brushed.  "What's wrong?"  he said.

"Maybe nothing," said Keith "but eight Waldahud ships are approaching
Starplex.  Do you know why?"

All four shoulders moved up and down.  "I have no idea."

"They are refusing to respond to hails, and--"

"I said I have no idea."  Jag turned around and faced the hologram where
the door had been.  All his eyes began tracking independently, each one
watching a different approaching ship.

"What kind of ships are those?"  asked Keith.  "Scouts?"

"They are the right size for that," said Jag.

"How many crew members aboard each?"

"Starships are not my field," said Jag.

Keith looked at the Waldahud at life sciences.  "You, there--Kreet, is
it?  How many people aboard such a ship?"

"Perhaps six," said Kreet.  "No more than that."

Two of the four bridge doors opened simultaneously.

Thoraid Magnor walked in through one, and Rissa Cervantes came in
through the other.  The Ib and the Waldahud vacated the helm and
life-sciences stations to make room for them.

"Eight ships are approaching Starplex," said Keith, to Rissa and Thor.

Rissa nodded.  "PHANTOM briefed us enroute.  But no additional ships
should have come through the shortcut until we gave the okay."  She
stood by her console, waiting for the chair to configure itself.

"Maybe they're here by accident," said Thor, tapping some keys on his
console while 'his chair rose from beneath the deck.  "When a new
shortcut comes on-line, the acceptable approach angles to select a
desired destination grow narrower.  They could have been sloppy in their
calculations.

Maybe they meant to go somewhere else."

"One pilot might make a mistake," said Keith.  "But eight?"

"The communications-lag time is up," said Denna.  "If they'd wanted to
reply to your latest message, they could have done so by now."  Rhombus
had entered a moment earlier, but was content to wheel up to a position
next to the ExOps workstation without getting Denna to vacate.

"Thor, if I give the order to get out of here," asked Keith, "can we
escape those ships?"

Thor shrugged.  "I doubt it.  They're blocking the shortcut, so we can't
go that way.  And see those roedial tings around their engine pods?

Those are associated with Waldahud Gatob-class hyperdrives.  Of course,
no one can use a hyperdrive this close to the green star, but if we
tried to get away, eventually we would be out in space that was flat
enough for hyperdrives to be engaged, and then they'd be on us in a
second."

Keith frowned.

"The ships are fanning out," said Thor.  "I'd call it an attack
formation."

"Attack?"  said Rhombus, lights strobing incredulously.

"Incoming message," said Denna.

Another part of the sky hologram was blocked off by a glowing border.

Inside it a Waldahud face appeared, framed by brown fur streaked with
copper.  "Lansing commanding Starplex," said the translated voice, "I am
Gawst.  Mark that name well: Gawst."  Keith nodded; to a Waldahud male,
credit was everything.  "We have come to escort Starplex back through
the shortcut.  You will surrender--"

"How long for a reply to reach them?"  asked Keith.

"--your ship to us."

Denna consulted a readout.  "Forty-three seconds."

"Cooperate," continued Gawst, "and no harm will come to your vessel or
crew."

"Thor, can we dive toward the shortcut apparently on one trajectory, but
at the last moment change direction so that we'll exit somewhere other
than where they'd expect?,'

The helm officer shook his head.  "Those little scouts might pull it
off, but Starplex's volume is three million cubic meters.  I can't make
it tap-dance."

"How long until those ships reach us?"

"They're moving at point-one-c," said Thor.  "They'll be on us in less
than twenty minutes."

"Lansing to Gawst: Starplex is Commonwealth property.

"Request denied.  Off.  Rhombus, let me know when they've received that
message."  Lianne Karendaughter strode onto the bridge.  "I want some
options, folks," said Keith.

"Option number one," said Lianne, taking her seat.

"Retreat.  The farther we are from the shortcut, the less likely they
will be able to coerce us through it."

"Right.  Thor, let's--"

"Forgive the interruption, Keith," said Rhombus.  "Your message has been
received."

"Good.  Thor, let's get out of here.  Full thruster power."

"I'll take us away at an angle," said Thor.  "We don't want to move into
the dark-matter field.  It's an obstacle course, and small ships will be
better able to handle it than we will."

"Fine," said Keith.  "Rhombus, see if you can get a watson with today's
mission logs through to Tau Ceti.  I want to alert Premier Kenyatta."

"Doing so.  But it will take over an hour to reach the shortcut from
here, and--excuse me: incoming message from Gawst."

"Lansing," said Gawst, "Starplex was built at the Rehbollo shipyards and
is of Rehbo!lo registry, and therefore is Waldahud property.  Let us
avoid as much unpleasantness as possible.  Once the ship is returned to
Rehbollo, we will release all crew members for immediate repatriation to
their home systems."

"Reply," snapped Lansing.  "Starplex's construction was funded by all
the Commonwealth worlds, and its registration is just a formality; all
ships require a homeworld of record.  Your claim is rejected.  If
necessary, this ship will defend itself against unlawful seizure.

Off."

"Defend itself?."  said Thor, shaking his head.  "Keith, this ship has
no armament."

"I'm well aware of that," snapped Keith.  "Lianne, 'give me a full
inventory of all shipboard equipment that can be used as weapons.  If
anything aboard can discharge an energy beam, or throw an object, or can
be made to blow up, I want to know about it."

"Working on it," said Lianne, hands dancing over her console.

"Starplex wasn't designed for fancy flying," said Thor, speaking to a
Keith hologram above the rim of his console.

"We'll wallow like a hippopotamus in heat compared to small fighters."

"then we'll fight them on their terms," said Keith.  "We'll defend
Starplex with our probeships."  He glanced at the list Lianne was
feeding through to his number-three monitor: geological digging lasers,
mining explosives, mass drivers used for launching probes.  "Lianne,
coordinate with Rhombus on getting as much of that equipment as possible
loaded into our five fastest probeships.  I want everything aboard in
fifteen minutes; I don't care what you have to rip apart to accomplish
that."

Denna Van Hausen finally moved away from the ExOps console and Rhombus
rolled into place.  Manipulator ropes darted across the controls, and
Rhombus's sensor web flowed half onto the panel to better interface with
the equipment.

"Even with a slapped-together armament," said Thor, "our probeships
aren't going to be able to outgun real fighting craft."

"i'm not planning to outgun them," said Keith.  "Starplex may be of
Waldahud construction, but our probeships aren't."

"Granted they may be reluctant to fire on Ibese craft," said Thor,
"but--"

"That's not what I'm thinking," said Keith.  "Unlike the approaching
craft, our probeships weren't designed by Waldahud engineers."

"Ah--and we have dolphins to pilot them!"  crowed Thor.

"Precisely," said Keith.  "PHANTOM, intercom with direct holo links:
Longbottle, Thinfin, Nickedfluke, Squint, Sidestripe, respond."

Drawn-out dolphin heads began to pop into existence above Keith's
console.

"Here."

"What happening is?"

"Thinfin, acknowledging."

"Yes, Keith?"

"Hello."

"We are about to be attacked by Waldahud craft," said Keith.  "Our
probeships are more maneuverable--if dolphins pilot them.  It will be
dangerous, but so will staying here and doing nothing.  Are you willing
to--"

"Ship is home ocean now--we protect!"

"If necessary, help will I."

"Ready to assist."

"Okay."

"I--yes, will do it."

"Excellent," said Keith.  "Proceed to launch bays.  Rhombus will give
you your ship assignments."

ThOr looked at his Keith hologram.  "There's no doubt that our ships are
more responsive--but dolphins have no experience with weapons.

They should each have someone else on board to act as gunner."

Rhombus's web flashed.  "Sentients will die if weapons are used."

"We can't stand by and not defend ourselves," declared Thor.

"To surrender our ship is better," said Rhombus.

"No," said Keith.  "I refuse to do that."

"But to kill--"

"No one need be killed," said Keith.  "We can shoot for the engine
units, try to disable the Waldahud ships without breaching their
habitats.  As for gunners--we're all just scientists and diplomats."

He considered for a moment.

"PHANTOM, consult personnel records.  Who would make the five most
proficient gunners?"

"Calculating.  Done: Wong, Wai-Jeng.  Smith-Tate, Helena.

Leed Jelisko em-Layth.  Cervantes, Clarissa.  Dask Honibo em-Kalch."

"Rissa .  . . ?"  said Keith under his breath.

"If the object is to fire geological lasers," said Thor, "then why not
use Snowflake?  She's senior geologist."

"We Ibs have lousy aim," replied Rhombus.  "Targeting works better when
you have a single point of view."

"PHANTOM," said Keith, "find replacements from other species for the two
Waldahudin, and set up an immediate intercom between all of them and
me."

"Done.  Intercom open."

"This is Director Lansing.  PHANTOM has determined that each of you has
the training and skill to best operate makeshift weapon systems aboard
our five dolphin-piloted probeships.  I can't order you, but we need
volunteers.  Are you up for it?"

A second row of holographic heads appeared above the dolphin faces.

"Good God, I--yes, I'll do it."

"Count me in."

"I'm not sure that I'm the right person, but .  . . yes, okay."

"On my way."

Rissa had moved over to stand .next to her husband.  "I'll do what I
can," she said.

Keith looked at her.  "Rissa .  . ."

"Don't worry, honey.  I gotta make sure you get to live all those
billions of years."

Keith touched her arm.  "Rhombus, assign each of them to a ship.

PHANTOM, convey them there as fast as possible."

"Doing so."

"Good work, everyone," said Keith, leaning forward in his chair, fingers
steepled in front of his face.

"JESUS!"  shouted Thor.  A tiny explosion was blossoming in the display.

"They've shot our watson out of the sky."

"Jag, analyze the weapon used," said Keith.  "At least we can figure out
what their armament is."

Jag glanced at a square monitor screen.  "Standard Waldahud police
lasers," he said.  But then he rose from his station and gestured toward
Melondent, who had been serving as physics officer during delta shift.

Jag touched a few keys.  "Transferring physical sciences to dolphin
station one," he said.  He turned to Keith.  "Perhaps .  . .

perhaps it would be best if I did not further participate.  Gawst did
not invoke the name of Queen Trath, so I assume that he and his
associates are acting without royal approval--an attempt to garner
considerable glory.  Still, they are Waldahudin.  Perhaps I should
return to my apartment."

"Not so bloody fast, Jag," Keith said, rising to his feet.  He glanced
at Lianne.  "Time to launch?"

"Ten, maybe eleven minutes."

Keith turned back to Jag.  "You had me move Starplex so that we wouldn't
be able to see the Waldahud forces massing on the green star's far
side."

"I deny that," said Jag, both sets of arms crossed behind his back.

"Your loyalties don't lie with the Waldahudin?"

"My loyalty is to Queen Trath, but there is no evidence that she
authorized the attempt to seize this ship.."

"Lianne,' how many watsons did Jag receive in the last two days?"

"Checking.  Three.  Two were from CHAT--"

"Which is located just outside the Waldahud home system--" said Keith.

"And the third was a commercial unit from a telecommunications utility
on Rehbollo."

"It contained personal news," said Jag, "related to an illness in my
family."

"Examine those watsons, Lianne," said Keith.  "I want to check the
messages that they carried."

"Once I had downloaded the data that I wanted," said Jag, "I released
the watsons for reuse--wiping the data first, of

COUrSe."

"We should be able to recover something," Keith said.

"Lianne?"

"Checking," she said, then a moment later.  "Okay, the watsons that came
for Jag are still on board.  We carry over a hundred of them, and those
three are still in the queue for reuse."  She pressed some keys.

"I've interfaced with all three; they're blank."

"Nothing at all to unerase?"

"No.  The data area has been wiped, then filled with a random pattern.

There's nothing left."

"I routinely use a level-seven wipe," said Jag.

"That's two levels above Earth military standards," said Keith.

"It leaves things more tidy," said Jag.  "You have often remarked on my
predilection for neatness."

"This is all crap," said Keith.  "I don't believe that it was
coincidence that you asked me to move the ship; the Waldahudin couldn't
have attacked en masse if we'd been there to see them popping out of the
shortcut one by one."

"I tell you, it is coincidence," said Jag.

Keith turned to face the InOps station.  "Lianne, immediately delist all
command authorities for Jag Kandaro em-Pelsh.

And terminate all jobs he has running."

Bleeps as keys were touched.  "Doing so," said Lianne.

"You do not have the authority to do this," said Jag.

"So sue me," said Keith.  He looked at the Waldahud.  "I was one of
those who argued against basing any part of Starplex on human military
structures, but if we had done so, at least we'd have a brig to throw
you in."  He faced a set of glowing camera eyes floating above the
seating gallery behind the workstations.  "PHANTOM, record new protocol.

Name: 'house arrest."  Authorizing authority, Lansing, G. K.

Parameters: Individuals under house arrest are denied access to all work
areas; PHANTOM will not open doors for them to such.  areas.  They are
also forbidden to use external communication equipment and to give
PHANTOM

commands above level-four housekeeping.  Understand?"

"Yes.  Protocol established."

"Record the following: As of this moment--0752 hours-- and effective
until terminated personally by me, Jag Kanclaro em-Pelsh is under house
arrest."

"Acknowledged."

Keith's voice was controlled.  "Now you may leave the bridge."

Jag folded both sets of arms behind his back again.  "I don't believe
you have the right to bar me from this room."

"A moment ago, you wanted to leave," said Keith.  "Of course, that was
back when you had the authority to launch a shuttle, and escape to the
armada."

Rhombus had left the External-Ops station and had rolled near to the
director's console.  Lights played over his sensor web, and the web's
strands had turned yellow, the color of rage.  "I support Keith," said
the cool British voice.  "You have undermined everything we have worked
for.  Leave the bridge voluntarily, Jag, or I will eject you."

"You can't do that.  It is against the operating code to assault a
fellow sentient."

Rhombus began rolling toward Jag, a living steamroller.

"Just watch me," he said.

Jag stood defiarit a moment longer.  Rhombus closed more of the distance
between them, his quartz-rimmed wheels glinting in the starlight of the
all-encompassing hologram.  The Ib's ropelike tentacles were lifted from
their usual bundle, darting in the air like angry snakes.  Jag finally
turned on his heel.  The starfield in front of him split open, and he
marched out.  The door closed.

Keith nodded thanks to Rhombus, then: "Thor, status of the Waldahud
ships?"

Thoraid Magnor looked over his shoulder at Keith.  "Assuming they've got
nothing better than standard police lasers, they will be within
effective range in three minutes."

"How long until our own ships are ready for launch?"

Rhombus's lights blinked out a reply as he rolled back to his
workstation.  "Two are ready to go now; the other three--grant me
another four minutes."

"I want to launch all five at once.  Everything goes out the door in two
hundred and forty seconds."  '

"Will do."

"We'll still be outnumbered, eight to five," said Thor.

Keith frowned.  "I know that, but it's only our five fastest ships that
are set up for dolphin pilots.  Rhombus, as soon as our ships are clear
of our docking bays, I want full power to our force screens.  Cut the
engines; divert everything to the screens.

"

"Will do."

"Lianne," said Keith, "I want to put a message for Tau Ceti in another
watson.  Shoot this one out a mass-driver tube.  Send it on a transfer
orbit that'll take it to the shortcut under momentum only; I want it to
fly all the way there without using power."

"It'll take a watson three days to get to the shortcut that way;" Lianne
said.

"I'm aware of that.  Calculate the trajectory.  How long do I have until
our ships launch?"

"Two-point-five minutes," said Rhombus.

Keith nodded, and touched the privacy button that erected four double
force-screen walls around his workstation, creating a sound-killing
vacuum gap.

"PHANTOM," he said, "search all computer records for research done by
Gaf Kandaro em-Weel and his associates, especially for material that's
never been translated from

Waldahudar."

"Searching.  Found."

"Display titles and abstracts in English."

Keith scanned the screen in front of him.  "Download into a watson
articles two, nineteen, and--let's see, better add
twenty-one, as well.  Encrypt everything under the password

Kassabian: K-A-S-S-A-B-I-A-N.  Record the following, and add it to the
watson as an unencrypted message:

"Keith Lansing to Valentina Ilianov, Provost, New Beijing.

Val, we're under attack by Waldahud ships, and I wouldn't be surprised
if you're under attack soon, too.  I have learned that there is a
theoretical way to destroy a shortcut, by flattening spacetime around
it, preventing it from anchoring in normal space.

If a Waldahud invasion force seems likely to over- whelm your fleet,
perhaps you will want to consider destroying your shortcut exit.

Doing so will, of course, effectively isolate Sol/Epsilon Indi/Tu Ceti
from the rest of the galaxy, and give the Walciahudin forces no way to
retreat.  Think long and hard before you do this, old end.  The
procedure can be gleaned from the articles appended to this message.

I've encrypted them.  The key is the last name of that woman we both
fancied on New New York all those years ago.  End."

"Done," said PHANTOM.

Keith tapped a key.  The privacy force screens vanished.

"Launch the watson, Lianne, he said.

"Doing so."

Keith watched the tiny canister drift away from Starplex.

His heart was pounding.  If Val decided to use the technique, there was
one other consequence that Keith hadn't spelled out: he and Rissa and
the rest of those from Earth aboard Starplex would never see home again.

"Here we go," said Rhombus.  "Five.  Four.  Three.  Two.

One.  Launching' PDQ.  Three.  Two.  One.  Launching Rum Runner.

Three.  Two.  One.  Launching Marc Garneau.  Three.

Two.  One.  Launching Dakterth.  Three.  Two.  One.  Launching Long
March."

The fusion flares of ten twin engines lit up the holographic sky as the
five probeships shot away from Star-plex's central disk.  The
approaching Waldahud ships were now close enough that they could be seen
directly, rather than as colored triangles.

"Force screens to maximum," said Rhombus.

"Open windows in the force screens and send the following via scrambled
comm laser direct to each of our ships," said Keith.  "No one is to fire
unless the Waldahudin shoot at us first.  Maybe a show of strength will
be enough to get them to back down."

"They already creamed one of our watsons," said Thor.

Keith nodded.  "But if shots are going to be taken at sentient beings,
the Waldahudin are going to have to start it."

,,incoming message," said Lianne.

"Let's see it."

Gawst's face appeared.  "Last chance, Lansing.  Surrender "No reply,"
said Keith.  He glanced at one of his monitors.

Starplex was still oriented with its lower telescope array facing the
green star, and toward the approaching fighters.

"Gawst's ship is coming toward us fast," said Thor.  "The other seven
are holding position about nine thousand klicks away."

"Steady, everyone," said Keith.  "Steady."

"He's firing!"  said Thor.  "Direct hit on our force screens.

No damage."

"How long can we keep deflecting his lasers?"', asked Keith.

"Four, maybe five more shots," said Lianne.

"the other Waldahud ships are moving in, trying to Surround us," said
Thor.

"Do you want our probeships to engage them?"  asked Rhombus.  Keith said
nothing.  "Director, do you want our probeships to engage them?"

"I--I didn't think Gawst would really fire," said Keith.

"qThey're taking up equidistant geodesic positions around us," said
Thor.  "If all eight ships shoot at us simultaneously and at the same
wavelength, it will overload our shields.

There will be nowhere to shunt the energy."

Holograms of the dolphin pilots and their gunners were floating above
Keith's console.  "Let me take out the ship nearest us," said Rissa,
flying with Longbottle aboard the Rum Runner.

Keith closed his eyes for a second.  When he opened them, he had found
his resolve.  "Do it."

"Shooting for the engine pod," said Rissa.

PHANTOM drew a red line in the holo sphere to represent the invisible
output of the geological laser, lancing from the bow of the Rum Runner
to the Waldahud craft.  The beam sliced along the length of the engine
pod, and a plasma tongue shot away from the ship.

"Hey," said Rissa, with a triumphant smile.  "Guess all that time
playing darts was good for something after all."

"Gawst is firing on Starplex again," said Thor.  "And one of the other
ships is going after the Rum Runner."

"Get out of there, Longbottle," said Keith.  The Rum Runner did an
arcing maneuver, exactly like a dolphin doing a backflip.  It completed
the move with its laser firing in the direction of the incoming ship,
which swerved to avoid contact with the beam.

"Gawst's ship has two lasers, one port and one starboard," said Thor.

"He's pounds ring them both at our lower radio telescope--man, he's
good.  He's letting our antenna's parabolic dish focus his beams onto
the instrument cluster."

"Rock $tarplcx," said Keith.  "l.os him."

The stars in holographic display danced left and right.

"He's still on us," said Thor.  "I bet--yup, he's done it.

Even with full shields, enough of his laser leaked through, and the dish
antenna foeused it.  He's taken out the deck-seventy sensor array,
and--"

Starplex shook.  Keith was startled; he had never felt the ship shake
before.  "The seven remaining Waldahud craft are firing on us in
sequence," said Thor.

"Keith to probeships: engage the Waldahudin.  Get them to stop their
attack on us."

"They'll overload our shields in sixteen seconds," said Lianne.

In the holo display, Keith could see the PDQ and the Long March firing
on two of the Waldahud ships.  The Waldahudin were trying to keep a
single force screen to their attackers while continuing to fire on
Starplex, but the probeships were maneuvering wildly, making it hard for
the Waldahudin to keep the screen positioned.  Glancing blows were
making it through.

An alarm started sounding.  "Force-screen failure imminent," said
PHANTOM's voice.

Suddenly one of the Waldahudin ships exploded silently; the Marc Garneau
had wheeled from firing on one ship to firing on the same one that the
PDQ had engaged.  The target ship had had no force screens deployed
along its bow.  Keith lowered his head.  The first casualties of the
battle--and, with hand-aimed lasers, no one would ever know if gunner
Helena Smith-Tate had aimed for the habitat, or had simply missed when
shooting at the engine pod.

"Two down, six to go," said Thor.

"Force-screen failure," announced Lianne.

The five dolphin-piloted ships began swooping wildly, their weapons
firing at' random.  The holographic display was crisscrossed with
animated laser beams, red for the Commonwealth forces, blue for the
attackers.

Suddenly Gawst's vessel began revolving around its bow-stern axis,
spinning like a corkscrew.  "What the hell's he doing?"  asked Keith.

It became apparent as PHANTOM drew in the two beams from Gawst's twin
laser canons.  With the ship rotating, the beams were forming a cylinder
of coherent light--turning twin pinpoint weapons into effectively a
wide-beam device.

Gawst was aiming up, toward the underside of Starplex's central disk,
beneath one of the ship's four main generators.

"If he does it right," said Thor, impressed despite himself, "he'll be
able to carve out the number-two generator, like a geologist taking a
core sample."

"Move the ship!"  snapped Keith.

The starfield wheeled.  "Doing so--but he's got a tractor beam locked on
us.  We--"

The ship rocked again, and a new alarm started wailing.

Lianne swung around to face Keith.  ""There's an internal hull breach on
deck forty, where the bottom of the ocean deck joins the central shaft.

Water is pouring down the shaft into the lower decks."

"Christ!"  said Keith.  "Did the Ibs screw up when they installed the
replacement lower habitats?"

Rhombus's web turned yellow with rage again, and the dots on it flared
brightly.  "Excuse me?"  he said sharply.

Keith raised his hands.  "It's just that--"

"The work was done perfectly," said Rhombus, "but this ship's designers
never thought we would be in a battle."

"Sorry," said Keith.  "Lianne, what's the procedure in a situation like
this?"

"There is no procedure," said Lianne.  "The ocean deck was considered
unbreachable."

"Can the water be contained with force fields?"  asked Keith.

"Not for long," said Lianne.  "The force fields we use in the docking
bays have enough strength to hold air at normal pressure against vacuum.

But each cubic meter of water masses a full ton; nothing short of the
ship's external forcefield emitters could hold back that much pressure,
and even if Gawst hadn't overloaded those, there's no way to aim them
inside the ship."

"If you turn off the artificial gravity in the central disk and on all
decks below it, at least the water won't flow down," said Thor.

"Good idea," said Keith.  "Lianne, do that."

"Security override," said PHANTOM's voice.  "Command disallowed."

Keith shot a look at the PHANTOM camera pair on his console.  "What the
--?"

"It's because of the Ibs," said Rhombus.  "Our circulatory system is
based on a gravity feed; we'll die if you turn off the gravity."

"Damn!  Lianne, how long to move all Ibs from decks forty-one through
seventy to the upper decks?"  ' "Thirty-four minutes."

"Begin doing that.  And get all dolphins out of the ocean deck--but tell
them to stand by with breathing apparatus, in case we have to send them
below into the flooded areas."

"If you evacuate starting from deck seventy," said Thor, "you can turn
off the gravity there first, and work your way "That won't make any
difference," said Lianne.  "By the time the water has fallen that far,
it'll have enough momentum to continue on downward even if gravity is no
longer pulling

"What about electrical shorting?"  asked Keith.

"I've already shut off the electrical systems in flooded areas," said
Lianne.

"If the ocean deck were to drain completely, how much of the lower decks
would it fill?"  asked Thor.

"One hundred percent," said Lianne.

"Really?"  said Keith.  "Christ."

"The ocean deck contains six hundred and eighty-six thousand cubic
meters of water," said Lianne, consulting a monitor screen.  "Even
including all sealed interdeck areas, the entire enclosed volume of the
ship below the central disk is only five hundred and sixty-seven
thousand cubic meters."

"Excuse me, but I think the PDQ is in trouble," said Rhombus, gesturing
with one of his ropes toward part of the holographic bubble.  Two
Waldahud ships were converging on the Starplex probeship, lasers
crisscrossing.

Keith's eyes darted between the holo display and the monitor on his
console showing the progress of the flooding.

"Wait," said Rhombus, "the Dakterth is coming up on the stern of the two
ships attacking the PDQ.  It should be able to draw their fire."

"How are the evacuations coming?"  asked Keith.

"On schedule," said Lianne.

"Are we leaking any water into space?"

"No; it's just an internal breach."

"How watertight are our interior doors?"

"Well," said Lianne, "the sliding doors between rooms seal when closed,
but they aren't strong.  After all, the door panels are designed so that
anyone can kick them free of their rails for emergency escape in case of
fire.  The weight of the water will burst them open."

"What genius thought of that?"  asked Thor.

"I think he helped design the Titanic," muttered Keith.

The ship rocked again, heaving back and forth.  In the holo display, a
cylinder carved out of Starplex's central disk, ten decks thick, was
tumbling against the night.

"Gawst has cut out our number-two generator," reported Lianne.  "I'd
evacuated that part of the engineering torus as soon as he started
carving into it, so there were no casualties.  But if he can get one
more of our generators, this ship won't be able to enter hyperdrive,
even if we could get far enough from the star to make that possible."

A burst of light caught Keith's eye.  The Dakterth had severed the
engine pod from one of the Waldahud ships that had been firing on the
PDQ.  The pod pinwheeled away.  It looked as though it was going to
crash into the cylindrical core that had been cut from Starplex, but
that was only a trick of perspective.

"What if we vent the water out into space."?"  asked Rhombus.

"We'd have to cut our own hole into the ocean deck to do that," said
Lianne.

"Where would be the easiest spot?"  asked Keith.

Lianne consulted a schematic.  "The rear wall of docking bay sixteen.

Behind it is the engineering torus, of course.  But right at that
location, the torus contains a filtration station for the ocean deck.

In other words, it's already filled with water right up to the back wall
of the docking bay, so you'd only have to carve a hole in the bay's wall
to get water to pour in."

Keith thought for a moment.  And then it hit him.  "Okay," he said.

"Get someone with a geological laser down to bay sixteen right away."

He turned to Rhombus.  "I know the Ibs need gravity, but what if we cut
the artificial gravity, and spin the ship instead?"

"Centrifugal force?"  said Lianne.  "People would be standing on the
walls."

"Yes.  So?"

"Well, and each deck is cross-shaped, so the apparent force of gravity
would increase as you went farther out into each

"But it would also keep the water from flowing down the central shaft,"
said Keith.  "Instead, it would be trying to press against the outer
walls of the ocean deck.  Thor, could you set up such a spin using our
ACS thrusters?"

"Can do."

Keith looked at Rhombus.  "How much gravity do you Ibs need for your
circulatory systems to work?"

Rhombus lifted his ropes.  "Tests have suggested that at least one
eighth of a standard-g is required."

"Below deck fifty-five," said Lianne, "even at the ends of the arms, we
won't get that much apparent gravity at any reasonable rotation rate."

"But that's only fifteen floors that have to have their Ibs evacuated
instead of forty," said Keith.  "Lianne, inform everyone of what we're
doing.  Thor, as soon as no Ib is left below deck fifty-five, start
spinning the ship.  Bleed off the artificial gravity as we come up to
speed."

"Will do."

"People should probably vacate the rooms at the ends of each arm,
because of the windows," said Lianne.

"Why?"  asked Keith.  "They're transparent carbon composite; they won't
break even if people are standing on them."

"Of course not," said Lianne.  "But the windows are angled at forty-five
degrees there, because the edges of the habitat modules slope at that
angle.  It'll be difficult to stand on them once the apparent gravity
shifts so that those sloping windows become slanted floors."

Keith nodded.  "Good point.  Pass on that advisory as well."

"Will do."

The holographic head of Longbottle aboard the Rum Runner spoke up.

"Polluted waters we are in.  Engines overheating."

Keith nodded at the holegram.  "Do what you can; if necessary, head away
from us.  Maybe no one will follow you."

Starplex rocked again.  "Gawst has started carving into the central disk
beneath our number-three generator," said Rhombus.  "And a second one of
his ships is carving in from the top of the disk, right above generator
one."

"Start spinning the ship, Thor."

The starfield holegram began to rotate.  The ship reeled again.  "That
took Gawst by surprise," said Thor.  "His lasers are skittering across
the entire undersurface of the central disk."

Lianne spoke up.  "Jessica Fong is in position inside docking bay
sixteen, Keith."

"Show me."

A frame appeared around part of the starfield holegram--now spinning at
dizzying speed.  Inside the frame, a picture of the interior of the
docking bay appeared, with a space-suited woman floating in midair.

She was tethered to the rear wall--the one that was shared with the
engineering torus--and the tether was pulled taut as the ship's rotation
flung her outward toward the inside of the curving space door.  The
bay's floor, crisscrossed with landing reference markers, was more than
a dozen meters below her feet, and its roof, covered with lighting
panels and housings for winches, was a dozen meters above her head.

"Open channel," said Keith, then: "Okay, Jessica.  Behind the bay's rear
wall, inside the engineering torus, is a water-filled ocean-deck
filtering station.  That station opens on to the ocean on the other
side.  Drill open a big hole in the docking bay's rear wall, Be careful,
though: when you do that, water is going to hammer through at you."

"I understand," said Jessica.  She reached to her waist and let out more
tether.  Keith watched breathlessly as she moved through the air across
the bay.  She wasn't wasting any time; meters of additional tether
appeared each second.  She finally reached the far side of the bay,
slamming against the curving surface of the space door.  For a horrible
moment, Keith thought she'd been knocked unconscious by the impact, but
she soon recovered from the blow and fought to bring the heavy
geological laser into position.  She was having trouble holding the unit
steady.  When she fired, her first shot crossed her own tether line,
severing it at its midpoint.  Fifteen meters of nylon line came crashing
down at her; the other fifteen meters whipped around far over her head
like a narrow yellow snake.  She was now pinned against the center of
the space door by the ship's spinning.

Fong's second shot went equally wild, taking out a junction box for the
in-bay lighting system.  Everything was plunged into darkness.

"Jessica!"

"I'm still here, Keith.  God, this is awkward."

In the frame, all that was visible was black--black, and then a pinprick
of ruby, as the laser found the rear wall.

Keith watched as the metal began to glow, soften, ripple----and then-The
sound of water rushing through, like a high-pressure fire hose.

Jessica continued to shoot the laser, perforating a giant square along
the rear wall.  A hole here, move the laser a centimeter, another hole,
shoot again, over and over-- The emergency lights came on, bathing the
entire bay in red.

Seawater erupted from the rear wall.  The perforated square of bulkhead
metal peeled back, then tore free, flinging across the bay, propelled by
a geyser of water behind it.

Keith cringed.  It looked as-though the metal wall fragment was going to
slap against Jessica, who was already being pummeled by wild fists of
water, but she, too, must have seen it coming.  There was an explosion
of flame behind her, scorching the wall.  She'd been smart enough to put
on a suit with a thruster pack, and had fired herself up and away just
in time.  The bay was filling with water, starting at the space door and
rising in toward the interior wall Jessica was soon slapped back against
the door.

Once the bay had filled, Keith spoke to her once more.

"Okay, now turn around and drill a.hole about ten centimeters in
diameter in the outer docking-bay door.  Hold the beam emitter right
against the door; you don't want to boil the water around you."

"Will do," she said, her space suit now a diving suit.  She stood on the
space door and held the gray metal cone of .her geological laser like a
jackhammer.  She then fired down between her feet.  Soon, part of the
space door was glowing cherry red, then white-hot, and then, and then .

. .

Starplex spun like a top against the night, green starlight winking off
its hull.

The five remaining Waldahud ships were approaching.

Two of the ships were.  coming in from above and three from below,
heading toward the ring of docking bays.  Doubtless the ship was
rotating too fast for any of the Waldahud pilots to notice the tiny
incandescent spot in the middle of the door to bay sixteen, a spot that
glowed, flared, and burned away.

And suddenly-- Water began to spray out into space, flinging away from
the rapidly rotating ship.  And as it hit vacuum, it evaporated
immediately into vapor, and then, once enough vapor had accumulated to
make for considerable pressure, the water recondensed into liquid, the
plankton, salt crystals, and oceanic detritus providing seeds for
droplet formation, and then here, shaded from the green star by the
intervening dark-matter field, it froze into ice-- Millions upon
millions of ice pellets, flinging away from Starplex at high speed,
propelled by the explosive force of all the water behind and by the
centrifugal force of the rapidly rotating ship.  Countless diamonds
against the night, winking green in the light of the nearby star-- The
first Waldahud ship was hit by a barrage of ice chunks, that ship's
speed toward Starplex being added to the pellets' own velocity, making
for a truly high-speed collision.  The initial half-dozen chunks were
deflected by the ship's force screens, shields designed for guarding
against single microme-teoroid impacts, not a sustained onslaughtn-Ice
pellets ripped through the Waldahud hull like teeth through flesh,
tearing up the habitat, expelled air freezing and adding to the
hailstorm in space On the bridge, Keith called out, "Now, Thor!  Rock
the ship!"

Thor compliedew streamer of ice chunks angled off in a different
direction, impacting a second Waldahud ship, ripping it open.  Then a
third ship exploded, a silent flower against the dark background, as
frozen bullets ripped into the tanks containing its
atmospheric-maneuvering fuel.

Thor rocked the ship the other way, and ice pellets were flung toward
the fourth remaining ship.  By this time, its pilot had come up with a
counterstrategy.  He rotated his own ship so that its fusion exhaust
cone faced toward Starplex, and he fired his main engine, melting the
ice into water drops, which immediately boiled into vapor before they
could hit his ship.

But the pilot of one of the other remaining ships had been unprepared
for this maneuver, or too preoccupied with saving his own tail by
heading toward the shortcut.  His course took him in the path of his
comrade's fusion exhaust, and the white-hot flames tore into his vessel.

It exploded, leaving only two ships--one of which was Gawst's.

The expanding ring of water pellets deflected most of the ship debris
away from Starplex, but the crew of the Waldahud craft that had tried
the fusion-exhaust trick wasn't so lucky.  A large, jagged piece of hull
rammed into their shipt it spinning away, out of control--directly
toward the field of dark matterlot seemed almost to regain control when
he was a few million kilometers away from the closest of the great gray
balls of gas, but by then he was already caught in its gravity.  It
would take hours for the deadly trajectory to play out its course, but
the ship was destined to crash into the darmat-- STARPLEX.

and, at that velocity, even the kind of soft impact that occurred when
regular matter hit dark matter would be enough to pulverize the vessel.

Gawst's ship was still intact, holding station with a tractor beam
beneath the central disk.  There was no way Thor could aim the
ice-pellet stream there.  Still, Starplex could keep spinning until
GaWst ran out of fuel, if need be .  . .

"Uh-oh."  PHANTOM's translation of the rippling lights on Rhombus.

Thor looked up.  "God damn," he said.

Emerging from behind the limb of the green star were one .  . . two .

. . five more Waldahud fighters.  Gawst had not been fool enough to use
all his forces on the initial attack.  One of the newcomers was a giant,
ten times the size of the smaller probecraft.

Starplex's five dolphin-piloted ships had backed off, avoiding the ice
barrage.  But now they were linking up in formation, and heading toward
the approaching attack force, determined to get to it before it could
get to their mothership.

And then .  . .

"What the hell?"  said Keith, gripping his armrests.

"Jesus "said Thor."  Jesus.

The vast field of dark matter had begun to move, slowly at first, but
now with gathering speed.  It was spinning out into lumpy streamers,
greenish on the side facing toward the rogue sun, inky black on the
other.  The streamers grew longer until they spre ad out over millions
of kilometers, tubes of gravel with planet-sized spheres distributed
along their length like knuckles on ethereal fingers.

The Starplex probeships dived above or below the stream- ers.  The
Waldahud pilots found their ships traveling in erratic courses, unable
to compensate for the streamers' gravitational attraction.  In the
spherical hologram, Keith could see the attacking ships staggering in
drunken, weaving lines, pulled off course by the hundreds of
Jupiter-masses within each dark-matter ribbon.

The streamers were growing with surprising speed.  Keith still had
trouble with the concept of macrolife living freely in space, but of
course most life-forms could move quickly when they wanted to .  . .

The pilots of the incoming Waldahud ships were realizing that they were
in trouble.  One of them aborted what had clearly been 'an attack run
toward Starplex, and was now veering off at a steep angle.  Another
fired its braking jets, the exhausts four ruby pinpricks against the
blackness.  But the darmats continued to reach for them, long, puffy
fingers against the night.

If the ships had been able to use hyperdrive, they could have escaped.

But the gravity well from the green star, and the shallower but still
significant wells created by the darmats, prevented that.

The farthest of the new fighters was now only a few kilometers ahead of
one of the dark-matter tendrils.  Keith watched as the gap was closed,
the ship disappearing within the fog of gravel.

Thor provided a schematic, showing the fighter's position within the
streamer--a streamer that now was no longer reaching forward, but had
started pulling back, its gravity dragging the Waldahud vessel with it .

. .

Soon a second dark-matter tentacle had enveloped another Waldahud ship.

A third fighter was trying desperately to get away; Keith could see the
flash of explosive bolts as it jettisoned its weapons clusters in order
to decrease its overall mass.  But the dark matter was still gaining on
it, Meanwhile, the two tendrils that had already caught ships were still
pulling back, and--that was curious--had begun curling in on themselves,
archirig away, like cobras made of ash.

The third small ship was finally caught, and its gray finger started
pulling back, too.  The giant Waldahud ship was also being approached
from above and below by separate dark-matter tentacles.  Only the fifth
new ship seemed likely to get away, although Keith's heart was pounding
as he saw that Rissa and Longbottle were now pursuing it.  His son's
face flashed in front of his eyes--still a kid at nineteen, the goatee
notwithstanding.  How would he break the news to him if his mother got
killed?

The first two tentacles had arched back into semicircles, the cups of
which were facing away from the green star.  At the same moment as the
large vessel was engulfed by the two converging streamers that had been
pursuing it, the first of the dark-matter fingers snapped forward like a
whip.  The Waldahud fighter that had been embedded in it shot ahead, out
of the tentacle, tumbling end over end.  Keith saw the pinpoint lights
of ACS jets firing, but the ship's wild rotation continued unabated

Keith's jaw fell open.  Good Christ--!

--as the ship was flung directly toward the green star.

The vessel continued to rotate over and over as the distance between it
and the star diminished rapidly.  The pilot finally managed to gain
control, but he was too close to the 1.5-million-kilometer-wide ball of
fire.  Prominences licked toward the incoming projectile-- --and the
ship turned to vapor in the star's upper atmosphere.

Keith shouted, "Rhombus, hail our probeships!"

"Channel open."

"Return to Starplex!"  said Keith.  "All ships, return at once to
Starplex!"

Four probeships acknowledged and changed course, but one was still
pursuing its target.

"Rissa!"  Keith shouted.  "Turn back!"

Suddenly the second dark-matter whip cracked across the night, sending
another Waldahud ship hurtling toward the green star.  Keith's head kept
snapping left and right between the twin horrors of Rissa's ship
receding from Starplex and the fighter's head-over-heels rush toward
destruction.

The Rum Runner was corkscrewing wildly as it approached the enemy
vessel.  Laser fire from the Waldahud's rear cannons kept missing the
probeship, or glancing off its force screens.  But, after a moment, the
firing stopped as the Waldahudin aboard presumably became absorbed in
the spectacle they, too, were no doubt monitoring.

The second ship the darmats had tossed toward the sun was rapidly
reaching its destination.  Lifeboats popped away from it, but their puny
motors weren't strong enough to let them achieve orbit around the star.

The last sight the dying Waldahu-din probably saw on their monitor
screens was the star's strange dumbbell-shaped sunspots, gray-black
splotches against a hell of liquid jade.

The PDQ and the Dakterth were returning to Starplex now.  Of course,
they had to approach from above or below to avoid the torus of hail
surrounding the ship.  Rhombus was using tractor beams to pull them down
onto the flat surface of the central disk.  There was no way to get them
into the docking bays--the ice prevented that--but there were emergency
docking clamps on both faces of the disk.

Rum Runner was still giving chase.  "Rissa!"  shouted Keith into his
mike.  "For God's sake, Rissa--come home!"

Suddenly the Rum Runner's laser erupted, PHANTOM dutifully drawing in
its beam on the holographic display.  It swept across the starscape.

Rissa's aim was perfect, severing the ship's engine pod from the craft
in one clean slice.

The pod tumbled against the night, a puff of expelled gas around it
shining like a halo of emeralds.  And suddenly-- The pod flared
brilliantly, brighter even than the nearby star, as it went up in a
fusion explosion.  Longbottle executed a crazed arcing maneuver to avoid
the expanding ball of plasma, then began a laser-straight path for
Starplex.  The engineless Waldahud ship shot away at an oblique angle
under momentum, unable to maneuver.

The third dark-matter whip cracked, sending another Waldahud fighter
pinwheeling across the firmament.  As this one passed by, Keith saw that
several of its hull plates had been deliberately blown away; the crew
had apparently preferred opening the ship to vacuum over cooking alive
as they plunged into the sun.

Next the combined double finger that had enveloped the huge Waldahud
ship began to rotate around its midpoint, playing out into a spiral
design like a galaxy as it did so, turning faster and faster.  PHANTOM
showed the location of the ship buried within one arm of the spinning
mass.  The rotation became more and more rapid, until finally, like an
athlete throwing a discus, the dark matter hurtled the giant ship away
from it.  The bigger ship managed to regain control before it impacted
the sun, but as it startedto alter its course, the white fusion flames
of its exhaust stark against the green inferno, a giant prominence
arched upward from the photosphere, engulfing it.

"Four of our five probeships are safely clamped to our hull," reported
Rhombus.  "And the Rum Runner will be back in eleven minutes."

Keith let out a heavy sigh.  "Excellent.  We must have everyone out of
the lower decks by now, right?"

"The final elevator is on its way up," said Lianne.  "Give it another
thirty seconds."

"Okay.  Keep the lower decks at zero-g so no more water will flow down.

Thor, stop spinning the ship."

"Will do."

"Director," said Rhombus, "Gawst's ship has attached itself to the
surface of our hull.  He's holding in place with a tractor beam."

Keith smiled "Fancy that--a prisoner of war."  He spoke loudly.

"Excellent work, everyone.  Thor, Lianne, Rhombus--excellent."

He paused.  "Thank God the darmats sided with us.

I guess it never hurts to be on speaking terms with the stuff that makes
up most of the universe, and--"

"Jesus.!"  Thor's voice.

Keith's head snapped up to face the pilot.  He'd spoken too soon.

Tendrils of dark matter were now closing on Starplex.

"We're next," said Rhombus.

"But we're orders of magnitude bigger than the Waldahud ships," said
Thor.  "Surely they can't toss us into the star?"

"Only a third of the dark matter participated in the attack on the
Waldahud forces," said Rhombus.  "If it all comes after us--PHANTOM, can
they do it?"

"Yes."

"Hail Cat's Eye," said Keith.  "I better talk to him."

"Locating vacant frequency," said Rhombus.  "Transmitting .  . . No
response."

"Thor, get us out of here," said Keith.

"Course?"

Keith considered for half a second.  "Toward the shortcut."

But he immediately realized that dark-matter tendrils had already
started to intervene between Starplex and that invisible point in space.

"No, change that," he snapped.

"Bring us in close to the green star, in the opposite direction.

And get Jag down here, PHANTOM."

"You ordered him barred from this room, sir," said the computer.

"I know that.  I'm giving you new instructions.  Get him down here right
away."

There was a moment's silence while PHANTOM conferred with Jag.  "He is
on his way."

"What're you got in mind?"  asked Rhombus.  Dark matter was approaching
Starplex on three sides, like a fist closing around a bug.

"Hopefully, a way to get out of here--if it doesn't kill us."

The starfield split open, and Jag walked in.  For the first time, Keith
saw a look of humility on the Waldahud's face.

Jag had presumably been watching the space battle, and had seen his
compatriots slammed into the emerald star.  But still some of the old
defiance was in his voice as he looked suspiciously at Keith.  "What do
you want?"

"I want," said Keith, his voice tightly controlled, "to slingshot
Starplex around the green star, and hurtle it into the shortcut from the
far side."

"Jesus God," said Thor.

Jag grunted a similar sentiment in his own language.

"Can it be done?"  said Keith.  "Will it work?"

"I--I don't know," said Jag.  "I would normally like a few hours to do
the calculations for something like that."

"You don't have hours--you've got minutes.  Will it work?"

"I do not--yes.  Maybe."

"Melondent," said Keith, "transfer control back to Jag's station."

"So doing," said the dolphin.

Jag slipped into his usual spot.  "Central Computer," he barked, "put
our trajectory on this monitor."

"You are barred from issuing nonhousekeeping commands," said PHANTOM.

"Override!"  snapped Keith.  "Jag's house arrest is suspended until
further notice."

The requested schematic appeared.  Jag squinted at it.

"Magnor?"

"Yes?"  said Thor.

"We have only perhaps ten minutes until we are engulfed.

You will need to fire all our ventral thrusters.  Copy my monitor six in
touch-screen mode."

Thor pressed buttons.  "Okay."

Jag ran a flat finger in an arc along the schematic.  "Can you manage a
course like that?"

"You mean on manual?"

"Yes, on manual.  We have no time to program the run."

"I--yes, I can do it."

"Execute it.  Execute it now!"

"Director?"

"How long until the Rum Runner is anchored to our hull?"

"Four minutes," said Rhombus.

"We don't have the time to wait for her," said Jag.

Keith turned to snap at Jag, but stopped himself.  "Options?"

he said generally to the people on bridge.

"I can put a tractor beam on the Rum Runner," said Rhombus.  "I won't be
able to haul her in before we hit the shortcut, but she should be
dragged over to it with us and hopefully Longbottle can pilot it
through."

the"o that.  Thor, get us out of here."

Starplex rushed toward the star at an oblique angle.

"Thrusters on full," said Thor.

"There's another problem we still have to deal with," said Jag, turning
to Keith.  "There's a good chance that I can get us to the shortcut, but
once there, we'll just plunge through it.  W, '

e won t have any time to slow down and do a controlled approach at a
specific angle, and with our deck-seventy hyperscope array damaged I
can't even predict which exit' we'll pop out of.  It could be anywhere."

The dark-matter fingers were still stretching toward Starplex.  "In a
few minutes, anywhere will be preferable to this place," said Keith.

"Just get us out of here."

The ship began to careen around the star.  Half of the bridge hologram
showed the green orb, its granular surface detail and dumbbell sunspots
visible.  Most of the rest of the view was cloudy, with dark-matter
tendrils eclipsing the background stars.  "Rhombus, do you have a solid
lock on the Rum Runner?"

"It's still four hundred kilometers away, and dark matter is starting to
intervene, but, yes, I've got it."

Keith breathed a sigh of relief.  "Good work.  Have you been able to
contact Cat's Eye, or any darmat?."

"They're still ignoring our hails," said Rhombus.

"We can't go in as close to the star as I would like,"'said Jag.

"There's not enough water left in the ocean deck to make an effective
shield, and our force screens are still burned out.  There's a
thirty-percent chance that the darmats will ensnare us."

Keith felt his heart pounding in his chest.  Starplex continued to swing
around the star in a parabolic course, the tendrils still stretching
toward it.  The Rum Runner was indicated in the hole bubble as a tiny
square, with an animated yellow tractor beam lancing out to it.  The
starfield wheeled--Thor was angling the ship as they grazed the star's
atmosphere.

Finally, Starplex reached the cusp of the parabola and, picking up
enormous velocity from slingshoting around the star, raced toward the
shortcut.  In the hole bubble, PHANTOM brightened the yellow
tractor-beam animation, indicating that additional power was being
pumped into it.

Starplex's course, four hundred kilometers closer to the star, was
significantly different from the path the Rum Runner would have been
following if it had been leoping around the orb under its own momentum.

"Two minutes to contact with the shortcut, mark," said Rhombus.

"We've never gone through a shortcut this fast before--no one has," said
Jag.  "People should secure themselves, or at least hold on to
something."

"Lianne, pass on that recommendation to all aboard," said Keith.

"All personnel," said Lianne's voice, reverberating over the speakers,
"brace for possible turbulence."

Suddenly a large, irregular object eclipsed part of the view.  "Gawst's
ship," said Lianne.  "He's pushed off our hull.  Probably thinks we've
all gone insane."

"I could grab him with another tractor," said Rhombus.

Keith smiled.  "No, let him go.  If he thinks his chances are better
with the darmats, that's fine by me."

"Eighty seconds, mark," said Rhombus, orange clamps rising up from the
invisible floor to hold on to his wheels.

"One-point-four degrees to port, Magnet," said Jag.

"You're going to miss the shortcut."

"Adjusting course."

"Sixty seconds, mark."

"Everyone hold on," said Lianne.  "It's--" Blackness.

Weightlessness.

"God damn it!"  Thor's voice.

Barking--Jag speaking'.  No translation from PHANTOM.

Flickering lights--the only illumination in the room: Rhombus saying
something.

"Power failure!"  shouted Thor.

Red emergency lighting came on, as did emergency gravity--a priority
because of the Ibs.  There were loud splashing sounds from either side
of the room: the water in the dolphin workstations had swelled up into
great dome shapes under zero gravity, domes that had collapsed,
splattering liquid everywhere as weight returned.

No holographic bubble surrounded the bridge; instead its blue-gray
plastiform walls were visible.  Keith was still in his chair, but Jag
was on the floor, obviously having lost his balance during the brief
period of zero-g.

The three consoles in the front row--lnOps, Helm, and ExOps--flickered
back into life.  The back-row stations were less critical, and stayed
off, conserving battery power.

"We've lost the Rum Runner," said Rhombus.  "It was cut loose when the
tractor beam died."

"Abort the shortcut insertion!"  snapped Keith.

"Way too late for that," said Thor.  "We're going through under
momentum."

Keith closed his eyes.  "Which way did the Rum Runner go?"

"No way to tell until I get my scanners back on-line," said Rhombus,
"but--well, we were hauling her in, meaning she would have been moving
pretty much in a line back toward the green star .  . ."

"The number-one generator blew," interjected Lianne, consulting
readouts.  "Battle damage.  I'm switching over to standby generators."

PHANTOM's voice: "Re-in-ish-il-i-zing.  Onqine."

The holographic bubble re-formed, beginning as a burst of whiteness all
around them, then settling down to the exterior view, dominated by the
green star, the rest obscured by the pursuing tendrils of dark matter.

Keith looked in vain for any sign of the Rum Runner.

Thor's voice: "Ten seconds to shortcut insertion, mark.

Nine.  Eight."

Lianne's voice, overtop, coming from the public-address speakers.  "We
should have full power back in sixty seconds.

Prepare--"

"Two.  One.  Contact!"  The red emergency lighting flickered.

The shortcut appeared like a ring of violet arcing around thems visible
above their heads and beneath their feet, as the infinitesimal point
expanded to swallow the massive ship.

Everything to the stern of the ring was the now familiar sky of the
green star and the pursuing dark matter.  But in front of the ring was
an almost completely black sky.  The passage through the shortcut took
only a few moments as Starplex hurtled through at breakneck speed.

Keith shuddered as he realized what had happened.

Rhombus's lights swirled in Patterns of astonishment.  Li-anne made a
small sound in her throat.  Jag was reflexively smoothing his fur.

All around was black emptiness, except for an indistinct white oval and
three smaller white splotches high above their heads, and a handful of
fainter white smudges tossed at random against the night.

They had emerged in the empty void of intergalactic space.

The white splotches weren't stars; they were whole galaxies.

And not one of them looked like the Milky Way.

Chapter XVIII

Rissa felt her throat constricting as the Rum Runner was flung away from
Starplex.

"What happened?"  she called.

But Longbottle was too busy to answer.  He was twisting and turning in
his tank, fighting to bring the ship under control.  On her monitors,
Rissa saw the green star swelling ahead of them, its surface a roiling
ocean of fiery emerald, jade, and malachite.

She fought down a wave of panic, and tried to assess for herself what had
gone wrong.  There's no way Keith would have cut power to the tractor
beam, so either Gawst had used some sort of interfering transmission to
sever the tractor, or Starplex had suffered a power failure.  Either
way, they'd been hurled away from the mothership, and almost directly
toward the star.  Through the clear wall between her air-filled chamber
and Longbottle's water-filled one, Rissa saw the dolphin sharply arcring
his body in what seemed to be a painful way, and bashing the side of his
head against the opposite wall, as if by that sheer additional effort he
could force the ship in the direction he wanted it to go.

Rissa looked at her monitors, and her heart skipped a beat.  She saw
Starplex disappear through the shortcut to--to wherever it had gone.-The
great ship's windows were dark, confirming that a power failure must
have occurred.  If the ship was truly without power, Rissa hoped it had
come through the shortcut network at New Beijing or Flatland--where
there would be other vessels to help it.

Otherwise, it might not be able to return through whatever exit it
emerged from--and a search of all the active exits might not be
completed before Starplex's batteries ran out, leaving it without life
support.

But Rissa only had a few moments to think about the fate of her husband
and colleagues; the Rum Runner was still heading toward the green star.

The bow window had already darkened considerably, trying to filter out
the inferno ahead of them.  Longbottle was still struggling with the
controls attached to his flukes and fins.  Suddenly he flipped around in
his tank, and Rissa saw the green star wheel away from view.

Longbottle was bringing the main engines around to face the star, and
firing them as brakes.  The ship rattled; Rissa could see Longbottle
disabling emergency cutoffs with presses of his snout.

"Sharks!"  shrieked Longbottle.  At first, Rissa thought it was just a
swear word for the dolphin, but then she saw what he was referring to:
tendrils of dark matter were now obscuring half the sky, the gray
spheres within the miasma of luster-quark gravel like the knots on a
cat-o'-nine-tails.

Longbottle twisted to his right, and the ship followed suit.

But soon a much more sharply defined blackness obscured their view.

"Ship of Gawst," said Longbottle.

"Damn," said Rissa.  She brought her hands down on the two grips that
controlled the geological laser.  She wasn't going to fire unless he
did, but -- Ruby dots on Gawst's hull.  Rissa'moved her thumb over the
laser's twin triggers.

Longbottle must have seen her do that.  "ACS jets," he said.  "Not
lasers.  He, too, tries to get away from darmats."

The view in the window changed again as Longbottle

. altered the Rum Runner's course.  Green star to the rear, enemy ship
to port, darmats to starboard and coming in above and below.  There was
only one course possible.

Longbottle jabbed controls with his snout.  "To the shortcut!"

he shouted in his high-pitched voice.

Rissa flipped keys, and one of her monitors showed the hyperspace map,
the maelstrom of tachyons visible around the exit point.

"More maneuverable are we than Starplex," said Long-bottle.

"An exit we may choose."

Rissa thought for half a second.  "Can you tell where Keith and the
others went?"

"No.  Shortcut rotates; I can match their angle of approach, but no time
to work out if that will mean we exit at the same place."

"Then--then go for New Beijing," said Rissa.  "Starplex will eventually
end up there for repairs--if it can."

Longbottle squirmed in his tank, and the Rum Runner arched upward then
down, coming at the shortcut from above and behind.  "Insertion in
seconds five," he said.

Rissa held her breath.  There was nothing visible on her monitors.

Nothing at all--A flash of purple.

A different starfield.

A massive black starship.

A starship firing on a flotilla of United Nations vessels.

Four--no, five!--dead hulks pinwheeling against the night, surrounded by
clouds of expelled atmosphere.

Everything was bathed in bloody light from the red dwarf that had
recently emerged from this shortcut.

It flashed in front of Rissa's eyes, the words fully formed, like a
chapter title on some future textbook screenThe Rout of Tau Ceti.

Waldahud forces attacking the Earth colony, seizing the one shortcut
that serviced human space, a giant battle cruiser easily dispatching the
tiny diplomatic craft normally stationed there-- A giant battle cruiser
that had all its force screens aimed forward, protecting it from the
returning fire being launched by the UN ships-- A giant battle cruiser
that the Rum Runner was directly behind.

Rissa had never killed before, had never even deliberately injured
before, had The Rout of Tau Ceti.

She swung the handles that aimed the laser, and leaned on the triggers.

PHANTOM wasn't here to animate in the beam for her, and the Waldahudin
battleship was too far away for her to see the red dot moving across its
hull -- Moving across its thruster fuel storage tanks--Ripping them
open--Igniting the fuel--And then-- A ball of light, like a
supernova-The bow window going completely black-- Longbottle arching in
his tank, moving the Rum Runner away from the expanding sphere of
debris.

Rissa took her hands off the triggers.  The window grew clear again.

She was shaking from head to foot.  How many Waldahudin had been aboard
a ship that size?  A hundred?  A thousand?  If they'd planned to
actually move on to Sol system and storm Earth and Mars and Luna,
perhaps as many as ten thousand soldiers--All dead.

Dead.

There were other Waldahudin ships in the area, but they were tiny
one-person fighter craft.  The big black vessel must have been their
mothership.

Rissa exhaled noisily.

"You acted well," said Longbottle gently.  "You did what you had to."

She said nothing.

The UN ships were banking now--New Beijing was a human-dolphin
colony--and coming in to attack the small Waldahud fighters.  The Rum
Runner buffeted slightly as it passed through the cloud of expelled
atmosphere from the destroyed battleship.

Rissa's console beeped.  She looked at the glowing red indicator, like a
drop of blood, but did not move.  Longbottle eyed her for a moment, then
nosed the similar control in his tank.  A woman's voice came over the
speakers.  "This is Liv Amundsen, commander of the United Nations police
forces at Tan Ceti, to Starplex auxiliary craft."  Rissa glanced at her
monitors.  Amundsen's ship was still three light-minutes away; no point
in trying a real-time conversation.  "We have identified your
transponder signal.  Thank you for your timely arrival.  Our casualties
are heavy--over two hundred dead--but you've saved New Beijing.  You can
bet they'll pin a medal on your chest, whoever you are aboard that ship.

Over."

A medal, thought Rissa.  Jesus Christ, they give medals.

"Rissa?"  said Longbottle.  "Do you want me--?"

Rissa shook her head.  "No.  No, I'll do it."  She tapped a key.  "This
is Dr. Clarissa Cervantes aboard the Rum Runner; I'm here with a dolphin
pilot named Longbottle.

Starplex was also attacked by Waldahud forces; it headed through the
shortcut network to destination unknown, but may require emergency
drydock facilities.  Can you accommodate?"

She watched the stars drift by as she waited for her signal to reach
Amundsen's ship, and the reply to make its way back.  The Waldahud
forces were repelled at Tau Ceti, said the history book in her mind.

But what was the next chapter?  Two hundred from Earth or its colonies
were dead .  . . Dolphins didn't believe in vengeance, but would the
humans demand it?  Would this be the one skirmish, or were we about to
see all-out war?

"Negative, Dr. Cervantes," came Amundsen's voice, at last.  "Our dock
facilities were the first thing the Waldahudin fired on."  Of course,
thought Rissa.  Pearl Harbor all over again.  "Suggest Starplex try the
Flatland drydocks--although it should be careful when moving through the
shortcut to there.  Remember, a G-class subgiant recently emerged from
that shortcut.  We can, however, offer repair services here for a small
ship such as yours."

Rissa looked at her monitors.  The battle wasn't quite over.  Police
ships were still engaging a few Waldahud craft, although some of the
invaders seemed to have surrendered, jettisoning their own engine pods.

"We more fuel need," said Longbottle to Rissa.  "And thrusters must be
allowed to cool--I overworked them badly."

"Fine," said Rissa into her microphone.  "We're coming in."  She' nodded
to Longbottle, and he rotated in his tank, moving the ship.

Rissa's heart was still pounding.  She closed her eyes, and tried not to
think of what she had done.

Chapter XIX

"Lianne, damage report!"  snapped Keith.

"I'm still tabulating everything from the battle, but there were no new
problems caused by the high-speed shortcut passage."

"What about casualties?"

Lianne tilted her head, listening to reports over her audio implant.

"No deaths.  Lots of bone fractures, though.  Couple of concussions.

Nothing too serious.  And Jessica Fong got out of docking bay sixteen
all right, although she has a broken hip and arm, and a lot of
bruising."

Keith nodded and breathed a sigh of relief.  He looked around the hole
bubble, trying to make out detail in the faint smudges of white against
black infinity.  "God," he said under his breath.

"All the gods," replied Jag, softly, "are a very, very long way from
here."

Thor turned around and looked at Jag.  "It is intergalactic space, isn't
it."

Jag lifted his upper shoulders in agreement.

"But--but I've never heard of any shortcut exit this far ou,,Thseaid
Lianne.

shortcuts have only existed for a finite time," 'said

Jag.  "Even hyperspace signals from one in intergalactic space might not
have reached any of the Commonwealth worlds yet."

"But how can there be a shortcut in intergalactic space?"

asked Thor.  "What's it anchored to'?."

"That's a very good question," said Jag, bending his head down to look
at his instruments.  "Ah--there it is.  Check your hyperspace scanner,
Magnor.  There's a large black hole about six light-hours from here."

Thor let out a low whistle.  "Adjusting course.  Let's give it a wide
berth."

"Are we in any danger from it?"  asked Keith.

"Not much, boss--unless I fall asleep at the wheel."

Jag touched some controls, and a framed-off area appeared in the holo
bubble.  But the space inside the frame was just as empty and black as
the space outside it.

"Normally you can see the accretion disk around a black hole," said Jag,
"but there's nothing out here to be pulled into it."  He paused.

"My guess is that it's an ancient black hole--it would have needed
billions of years to get out here.  I suspect it's the remains of a
binary star system.  When the larger component went supernova, it could
have caused an asymmetric 'kick which propelled the resulting black hole
out of its home galaxy."

"But what would have activated this shortcut?"  asked Lianne.

Jag lifted all four shoulders.  "The hole would pull in any matter that
wanders by.  Something that was being sucked in by it probably fell
through the shortcut instead."  Jag tried to sound jaunty, but it was
clear even he was staggered by it all.  "We're actually pretty
lucky--shortcuts in intergalactic space are probably as rare as mud
without footprints."

Keith turned to Thor.  He made an effort to keep his voice calm,
controlled.  He was the director; no matter how much Starplex usually
behaved like a research lab rather than a sailing vessel, he knew all
eyes would be on him, looking for strength.  "How soon can we go back
through the shortcuT' he asked.  "How soon can we go get the Rum
Runner?"

"We've still got major electrical problems," said Lianne.

"I wouldn't want to move the ship until those are stabilized-- and I'll
need at least three hours for that."

"Three hours!"  said Keith.  "But-- ' try to cut it down," said Lianne.

"What about sending a probeship through to help Rissa and Longbottle?"

asked Keith.

The room was silent for a moment.  Rhombus rolled over to the command
workstation, and touched Keith's forearm lightly with one of his
manipulator ropes.  "My friend," he said, PHANTOM translating the low
intensity of his lights as whispering, "you can't do that.  You can't
put another ship in danger."

I'm the director, thought Keith.  I can do what I damn well please.  He
shook his head, trying to get control.  If anything had happened to
Rissa .  . .

"You're right," he said at last.  "Thanks."  He turned to Jag, and felt
his heart rate increasing.  "I should put you back under house arrest,
you .  . ."

"'Pig,'" said Jag, his underlying bark an excellent mimicking of the
English word.  "Go ahead and say it."

"My wife is out there somewhere--possibly dying.  Long- bottle, too.

What the hell were you trying to accomplish?"

"I admit nothing."

"The damage to this ship will cost billions to repair.  The Commonwealth
will bring charges against you, you can be sure of that--"

"You will never be able to prove that my request to move Starplex had
anything to do with the subsequent events.  You can revile me all you
wish, human, but even your unenlightened courts require proof to
substantiate a charge.  The dark-matter being I wanted to examine did
indeed have an unusual hyperspace footprint; any astronomer will verify
that.  And it was indeed invisible from Starplex's vantage point before
the move--"

"You said that darmat was about to reproduce.  It hasn't done a thing."

"You are spoiled by being a sociologist, Lansing.  In the hard sciences,
we occasionally have to face the reality that some of our theories will
actually be disproven."

"It was a rose--"

"It was an experiment.  Suggesting anything else is conjecture; persist
publicly in it, and I shall bring defamation charges against you."

"You bastard.  If Rissa dies--"

"If Dr. Cervantes dies, I will mourn.  I wish her no ill.  But for all
we know, she and Longbottle have maneuvered through the shortcut to
safety.  It is my compatriots who have died today, not yours."

Lianne spoke softly from her console.  "He's right, Keith.

We've lost equipment, and we've got several people who are injured.

But no one from Starplex is dead."

"Except possibly Rissa and Longbottle," snapped Keith.

He took a deep breath, trying to calm himself.  "It's all about money,
isn't it, Jag?  Of all the Commonwealth homeworlds, Rehbollo's economy
took the biggest hit when interstellar commerce opened up.  You guys
never build two things the same--"

"To do so is an affront to the God of Artisans--"

"To do so is efficient, and your factories and workers were not.  So
you tried to goose the government coffers.

Even disassembled for parts, Starplex would be worth trillions--lots of
glory in that.  And if war erupted over its seizure, well, nothing like
a little war to give the economy a boost, eh?"

"No sane being wants war," said Jag.

"PHANTOM," snapped Keith, "Jag is again under house arrest."

"Acknowledged."

"It may please the punitive in you to do that," barked Jag.

"But this is still a science vessel, and we are the first Commonwealth
beings ever to be in intergalactic space.  We should determine our exact
location--and I am the most qualified person to undertake that task.

Rescind the arrest order, shut up and leave me alone, and I shall try to
figure out where we are."

"Boss," said Thor gently, "he's right, you know.  Let him help."

Keith fumed for a few moments longer, then nodded curtly.  But when he
did nothing further, Thor spoke into the air.  "PHANTOM," he said.

"Cancel house arrest on Jag."

"Cancellation requires authorization from Director Lansing."

Keith exhaled noisily.  "Do it--but, PHANTOM, monitor every command he
issues.  If any of them seem unrelated to determining our location,
notify me at once."

"Acknowledged.  House arrest ended."

Keith looked at Thor.  "What's our current heading?"

Thor consulted his instruments.  "We're still on a modified version of
the parabolic course we used to slingshot around the green star.

Obviously, the path changed when we ceased to be under that star's
gravitational influence, so--"

"Magnor," said Jag, interrupting.  "I need you to rotate the ship in a
Gaf Wayfarer pattern; we are missing one hyperscope array, but I need a
parallactic full-sky hyperspace scan."

Thor tapped some keys.  The holographic bubble around the bridge began a
complex series of rotations, but because the bubble was empty save for a
few indistinct smudges of white, the tilting and turning didn't cause
vertigo.  The pilot looked at Keith again.  "As for getting home, the
shortcut exit behind us shows in hyperspace just like every other one
I've ever seen, complete with zero meridian.  Assuming the damned things
still work the same way over millions of light-years, once Lianne gets
our full electrical system back on-line, I should be able to put us back
at any active shortcut you specify."

"Good" said Keith.  "Lianne, how badly damaged were we in the battle?"

"Decks fifty-four through seventy are flooded," she said, into a
hologram of Keith's head, "and everything from deck forty-one down has
some water damage.  Also, all decks below the central disk took a heavy
hit of radiation as we careened around the green star; I advise
declaring the entire lower half uninhabitable."  She paused.  "The
Starplex 2 team is going to be pissed off with us--we've now fried both
sets of lower-habitat modules."

"What about our shields?"

"Our forcefield emitters were all overloaded, but I've already got my
engineers working on repairs; we should have minimal screens within an
hour.  In a way, it's good we came out in intergalactic space.  The
chances of running into a micrometeoroid out here are slim."

"What about the damage done when Gawst carved out our number-two
generator?"

"My teams have put temporary bulkheads in place around the hole where it
was removed," said Lianne.  ''That should hold until we get back to a
spacedock."

"And the other generators?"

"Number three has had all its electrical connections severed.

I've got a crew working on hooking it back up again, but I don't know if
we've got enough wide-gauge fiber-optic cable in stock to do the job; we
may have to manufacture some.

Anyway, until we get it back on-line, we won't be able to use the main
engines.  One of the other Waldahud ships had started carving out the
number-one generator, as well.  That's the one that quit, causing the
power failure.  We should be able to repair that damage, though."

"And what about the docking bays?"

"Bay sixteen is filled with frozen water," said Lianne.

"Also, three of the five probeships that were involved in the battle are
in need of repairs."

"But we're still spaceworthy?"  asked Keith.

"I want to schedule about three weeks in dock for repairs, but, yes,
we're in no immediate danger."

Keith nodded.  "In that case, Thor, as soon as Lianne says we're ready
for powered flight, I'll want you to plot a course through the shortcut
that will pop us out where we started, back near the green star."

Thor's orange eyebrows lifted.  "I know you want to rescue the Rum
Runner, Keith, but if they survived, Long- bottle will have already
taken them out of there through the shortcut."

"Probably so, but that's not why I want to go back."  He .looked over at
Rhombus.  "You were right a few minutes ago, my rolling friend.

I've got to keep my priorities straight.

Contact with other life is why Starplex was built in the first place.

I'm not going to let the Commonwealth become like the Slammers, cutting
off all communication because of a misunderstanding.  I want to talk to
the darmats again."

"They tried to kill us," said Thor.

Keith raised a hand.  "I'm not feel enough to give them a second chance
to toss us into the green star.  Can you plot a course that will bring
us out of the shortcut, whip us around that star, then bring us back to
the shortcut, diving through on a vector that will take us out at the
Flatland 368A exit?"

Thor considered for a moment.  "I can do that, yes.  But F368A?  Not New
Beijing?"

"For all we know, the attack on Starplex was not an isolated event.

New Beijing may be under siege.  I want to go to a neutral location."

A pause.  "Now, with the course I've described, will the darmats be able
to grab us again?"

Thor shook his head.  "Not at the speed we'll be going, unless they're
all lying in wait for us just outside the exit."

"Rhombus," said Keith, "as soon as Lianne's got the appropriate systems
back on-line, send a probe through to the green-star exit.  Include a
hyperspace scanner on it so you can locate the darmats by the dents they
make in spacetime.  Also, have it do a wide-spectrum radio scan, in case
Waldahud reinforcements have arrived.  And"--Keith tried to keep his
voice calm--"have it check for the Rum Runner's transponder code."

"It'll be at least thirty minutes before we can do that," said Lianne.

Keith pursed his lips, and thought about Rissa.  If she were gone, it
would take all the billions of years he had left to get over the loss.

He looked at the smudges of galactic light against the abyss.  He didn't
even know which direction to look in, which way to concentrate his
thoughts.  He felt incredibly small, insignificant, and lonely beyond
belief.

There was nothing to focus on in the holo bubble--nothing sharp, nothing
well defined.  Just an abysswan ego-crashing emptiness.

Suddenly there was a strange sound like a dog's cough from his left;
PHANTOM translated it as an expression of "absolute astonishment."

Keith turned to face Jag, and his mouth hung open as he stared at the
Waldahud.  He'd never seen Jag's fur do that before.  "What's wrong?"

"I--I know where we are," said Jag.

Keith looked at him.  "Yes?"

"You're aware that the Milky Way and Andromeda have about forty smaller
galaxies bound to them gravitationally, right?"  said Jag.

"The Local Group," said Keith, irritated.

"Exactly," said Jag.  "Well, I started off by trying to find some of the
Local Group's distinctive features, such as superbright S Doradus in the
Large Magellanic Cloud.  But that didn't work.  So I sorted the catalog
of known extragalactic pulsars by distance--which corresponds.

to age, of course--and used their signature radio pulses to orient
myself."

"Yes, yes," said Keith.  "And?"

"And the closest galaxy to us right now is that one there."

Jag pointed beneath his feet to a fuzzy spot in the hologram.

"It's about five hundred thousand light-years from here.  I have
identified it as CGC 1008; it has several unique attributes."

"All right," said Keith, sharply.  "We're half a million light-years
from CGC 1008.  Now, for us nonastrophysics types, how far is CGC 1008
from the Milky Way?"

Jag's barking was subdued, almost soft.  "We are," said the translated
voice, "six billion light-years from home."

"Six .  . . billion?"  asked Thor, turning to face Jag.

Jag lifted his upper shoulders.  "That is correct," he said, his voice
still soft.

"That's .  . . staggering," said Keith:

Jag lifted his upper shoulders.  "Six billion light-years.  Sixty
thousand times the Milky Way's own diameter.  Twenty-seven hundred times
the distance between the Milky Way and

Andromeda."  He looked at Keith.  "In terms you nonastrophys-ics types
might use, one hell of a long way."

"Can we see the Milky Way from here?"  asked Keith.

Jag made a gesture with his arms.  "Oh, yes," he said, his barking still
subdued.  "Yes, indeed.  Central Computer, magnify sector 112."

A border appeared around a portion of the holographic bubble.  Jag left
his workstation and walked toward it.  He squinted for a moment, getting
his bearings.  "There," he said, pointing.  "That one there.

And that's Andromeda next to it.

And this is M33, the third-largest member of the Local Group."

Rhombus's lights twinkled in confusion.  "Boundless apologies, but that
can't be right, good Jag.  Those aren't spiral galaxies.  They look more
like disks."

"I'm not mistaken," said Jag.  "That is the Milky Way.

Since we are now six billion light-years from it, we are seeing it as it
looked six billion years ago."

"Are you sure?"  said Keith.

"I am positive.  Once the pulsars had told me approximately where to
look, it was easy enough to identify which galaxy was the Milky Way,
which was Andromeda, and so on.  The Magellanic Clouds are too young for
any light from them to have reached this far out, but globular clusters
contain almost exclusively ancient first-generation stars, and I've
identified several specific globulars associated with both the Milky Way
and Andromeda.  I am sure of it--that simple disk of star is our home
galaxy."

"But the Milky Way has spiral arms," said Lianne.

Jag turned to her.  "Yes, without question, the Milky Way today has
spiral arms.  And, just as surely, I can now say that when it was six
billion years younger, it did not have spiral

"How can that be?"  asked Thor.

"That," said Jag, "is a vexing question.  I confess that I would have
expected a Milky Way even half its present age to still have arms."

"Okay," said Keith.  "So the Milky Way gains spiral arms sometime in the
interim."

"No, it is not okay," said Jag, his bark returning to its usual
sharpness.  "In fact, it has never made any sense.  We've never had a
good model for galactic spiral-arm formation.  Most models are based on
differential rotation--the fact that stars near the galactic center make
several orbits around the core in the time it takes for those farther
out to complete just one.  But any arms that resulted because of that
should be temporary phenomena, enduring at most for a billion years. Oh,
we should see some spiral galaxies, but there is no way that three out
of every four large galaxies should be spirals--which is the ratio we
actually observe.  Ellipticals should far outnumber spimls, but they do
not."

"Obviously, then, there's a flaw with the theory," said Keith.

Jag lifted his upper shoulders.  "Indeed.  We astrophysics types have
been limping by for centuries with something called 'the density-wave
model' for explaining the abundance of spiral galaxies.  It proposes a
spiral-shaped disturbance that moves through the medium of a galactic
disk, with stars getting caught up in it--or even being formed by it--as
the wave rotates.  But it has never been a satisfactory theory.

First, it fails to account for all the different types of spiral forms,
and, second, we don't have a good answer as to what would cause these
imagined density waves in the first place.  Supernova explosions are
sometimes cited, but it's just as easy to model such explosions
canceling each other out as it is to get them to build up long-duration
waves."  He paused.  "We've had other problems with our galaxy-formation
models, too.  Back in 1995, human astronomers discovered that distant
galaxies, observed when they were only twenty percent of the current age
of the universe, had rotational rates comparable to what the Milky Way
has today--that's twice as fast.  as they should have been rotating at
that age, according to theory."

Keith thought for a second.  "But if what we're seeing right now is
correct, then spiral galaxies like ours must somehow form from simple
disks, right?"

Another lift of the Waldahud's upper shoulders.  "Perhaps.

Your Edwin Hubble proposed that galaxies each start as a simple sphere
of stars, gradually spin out into a flat disk, then develop arms that
open up more and more over time.

But although we now have observational proof that that sort of evolution
does indeed happen"--he gestured at the disk of stars in the glowing
frame--"we still don't have an explanation for why the evolution takes
place, or why the spiral structures persist."

"But you say three quarters of all large galaxies are spirals?"  asked
Lianne.

"Wellll," said Jag, PHANTOM translating a hissing bark as a protracted
word, ."actually, we don't know much directly about the ratio of
elliptical to nonelliptical galaxies in the universe at large.  It's
hard to make out structure in dim objects that are billions of
light-years away.  Locally, we see that there are many more spirals than
there are ellipti-cals, and that spirals contain a preponderance of
young blue stars, whereas our local ellipticals contain mostly old red
stars.  We've assumed, therefore, that any vastly distant galaxy that
showed lots of blue light--after correcting for redshift, of course--was
a spiral, and any that showed mostly red was an elliptical, but we
really don't know that for sure."

"It's incredible," said Lianne, looking at the image.

"So--so if that's how it looked six billion years ago, then none of the
Commonwealth homeworlds yet exists, right?  Is there--do you suppose
there's any life in the galaxy now?"

"Well, 'now' is still 'now,' of course," said Jag.  "But if you're
asking if there was any life in the Milky Way hack when that light
started its journey to us, I would say no.

Galactic cores are very radioactive--even more so than we used to think.

In a large elliptical galaxy, such as we're seeing here, the whole
galaxy is essentially the core.  With stars that close together, there
would be so much hard radiation everywhere that stable genetic molecules
wouldn't be able to form."  He paused.  "I guess that means it's only
middle-aged galaxies that can give rise to life; young, armless ones
will be sterile."

There was silence on the bridge for a time, broken only by the gentle
hiss from the air-circulating equipment and the occasional soft beep
from a control panel.  Each person contemplated the small fuzzy blot of
light that one day would give rise to all of them, contemplated the fact
that they were farther out in space than anyone had ever been before,
contemplated the vastly empty darkness all around them.

Six billion light-years.

Keith remembered reading about Borman, Lovell, and Anders, the Apollo 8
astronauts who had circled the moon over Christmas of 1968, reading
passages from Genesis back to the people on Earth.  They had been the
first human beings to get far enough from the homeworld so that they
could cup it in an outstretched hand.  Maybe more than any other single
event, that view, that perspective, that image, had marked childhood's
end for humanity--the realization that all their world was one tiny ball
floating against the night.

And now, thought Keith, maybe--just maybe--this image was the one that
marked the beginning of middle age: a still frame that would become the
frontispiece of volume two of humanity's biography.  It wasn't just
Earth that was 'tiny, insignificant, and fragile.  Keith lifted his hand
and reached out toward the hologram, cupping the island of stars in his
fingers.  He sat silently for a long moment, then lowered his hand, and
allowed his eyes to wander over the overwhelming dark emptiness that
spread out in all directions.

His gaze happened to pass over Jag--who was doing exactly what Keith had
done a moment ago, using one of his hands to cup the Milky Way.

"Excuse me, Keith," said Lianne, the first words spoken by anyone on the
bridge for several minutes.  Her voice was soft, subdued, the way one
would talk in a cathedral.  "The electrical system is repaired.  We can
launch that probe anytime you like."

Keith nodded slowly.  "Thank you," be said, his voice wistful.  He
looked once more at the young Milky Way floating in the darkness, and
then said softly, "Rhombus, let's have a look at what's going on back
home."

Chapter XX

"Launching probe," said Rhombus.

In the holo bubble, Keith could see the silver-and-green cylinder moving
away from the ship, illuminated by a tracking searchlight on Starplex's
hull.  It looked out of place against the fuzzy splotches of distant
galaxies.  Soon the probe touched the shortcut and disappeared.

"The mn should only take about five minutes," said Rhombus.

Keith nodded, trying to contain himself.  He didn't know which he wanted
more: to have the probe report that it had detected Rissa's
transponder--meaning the Rum Runner was at least still intact--or for it
to report nothing, meaning the probeship might have made it through the
shortcut to safety.

Time passed, and Keith's nervousness grew.  A watched pot never boils,
but .  . .

He looked up at the trio of clocks floating in space above the hidden
port-side door.  "How long has it been?"

"Seven minutes," said Rhombus.

"Shouldn't your probe be back by now?"

Lights moved up the Ib's web.

"Then where the hell--"

"Tachyon pulse!"  announced Rhombus.  "Here it comes."

"Don't wait until it's docked," said Keith.  "Download the data by radio
and display it."

"Doing so with delight," said Rhombus.  "Here we go."

The probe's scan was low resolution, and video, rather than holographic.

A part of the all-encompassing bubble was framed off in blue, and
playback of the flatscreen images the probe had recorded began to
appear.

"What the--?"  said Keith.  "Rhombus, did you use the correct angle of
approach?"

"Yes--to within a fraction of a degree."

Jag said a Waldahudar swear word.  By default, PHANTOM didn't translate
profanity, but Keith felt like swearing himself.  "That's not where we
came from," he said.

Jag's fur was motionless.  "No," he said.  The image in the screen
showed tightly packed red stars.  "At a guess, I'd say it's not even
anywhere in the Milky Way.  That looks like the inside of a globular
cluster.  There are dozens associated with CGC 1008, so it might even be
one of those."

"Which means--"

"Which means," said Thor, lifting his hands from the helm console, "that
we can't go home.  We don't have the correct address."

"The latitude/longitude coordinate system must not work the same way
over such great distances," said Lianne.

Keith's voice was small.  "Even at full hyperdrive--" Jag snorted.

"Even at full hyperdrive, to cover six billion light-years would take
two hundred and seventy million years."

"All right," said Keith.  "We'll try sending probes through in a search
pattern.  Rhombus, start by piercing the tachyon sphere around the
shortcut at the north pole, then work your way down, trying again at
every five degrees of latitude and five degrees of longitude.  Maybe, if
we're really lucky, we'll see something we recognize in the scans they
bring back."

Rhombus began launching probes, but it soon became apparent that they
were all going to either the globular cluster, or to another region of
space where the sky was dominated by a ring-shaped nebula.

"From the point of view of this shortcut," said Rhombus, "there are only
two other active shortcuts.  I suppose that means we're lucky our
initial probe came back to us--it only had a one-in-two chance of doing
so."

"Not much of a choice, is it?"  said Keith.  "Here on the periphery of a
black hole in intergalactic space; off in a globular cluster--presumably
full of old, lifeless stars; or over to that ring nebula."

"No," said Jag.

"No what-?"

"No, we cannot be limited to those choices."

Keith let out a sigh of relief.  "Good.  Why not?"

"Because the God of Alluvial Deposits is my patron," said the Waldahud.

"She would not abandon me."

Keith felt his heart sink.  He stopped himself before he snapped out
something nasty.

"There has to be a way back," said Jag.  "We came here, and therefore we
must be able to return.  If only we--"

"Speed!"  shouted Lianne.

Keith looked at her.

"Speed!"  she said.  "We went through the shortcut at very high speed.

Perhaps the velocity range at which you enter a shortcut selects which
other family of shortcuts you have access to.  We've always previously
done it at very low relative velocities in order to avoid impacts.

After all, one does go through a shortcut blind, not knowing for sure
what's on the other side.  But this time, we whipped into it at
substantial fraction of light-speed.  We may have keyed into another
level of shortcuts by doing so."

Keith turned to Jag.  He lifted all four shoulders.  "It's as good an
explanation as any."

"Rhombus, launch another probe," said Keith.  "Put it on a long
trajectory that will let it accelerate to the same speed we were at when
we passed through the shortcut, and aim for the exact latitude and
longitude that corresponds to where we came from."

"Doing so with transcendent joy," said the Ib.

The probe was launched, built up speed, pierced the shortcut.  They all
held their breaths.  Even Rhombus's pump, which operated without
guidance from the pod, apparently sensed that something important was
happening.

Its central orifice temporarily halted its constant sequence of open,
stretch, compress, and close.

And then the probe returned.  Rhombus's ropes whipped his console,
making loud slapping sounds as they did so, and the framed-off area
filled with the probe's recorded images.

Thor was grinning from ear to ear.  "I never thought I'd be glad to see
that thing again," he said, jerking a thumb at the image of the green
star.

Keith breathed a long sigh of relief.  "Thank--thank the God of Alluvial
Deposits."

"According to the probe's hyperscope, the darmats have moved well away
from the exit point," said Rhombus.

"Excellent.  Thor, take us home.  Execute the course we discussed
earlier.  I want to have a word with Cat's Eye."

Chapter XXI

Starplex moved through the intergalactic abyss toward the shortcut.

The ship--seeming minuscule amidst all the emptiness--gathered speed as
it approached, Thor revving up the thrusters.  When it touched the
shortcut, a ring of violet fire passed over the vessel as it traversed
six billion light-years -- 60,000,000,000,000,000,000,000 kilometers--in
the blink of an eye.  There was a spontaneous cheer from those on the
bridge as the holographic bubble was filled again with countless stars.

Keith felt his eyes stinging, the way they had the last time he'd
returned to Earth.

Thor immediately began making manual adjustments; they hadn't been
monitoring the green star long enough to know its exact trajectory away
from the shortcut, and his guess of where it would be was somewhat off.

He soon had the ship settled into the parabolic course Keith wanted--a
much wider parabola than their previous passing, avoiding any dangerous
proximity to the green star, which now once again dominated the holo
bubble.

"Scan for the Rum Runner's transponder," said Keith.

"Doing so," said Lianne.  But then, a moment later, "I'm sorry, Keith.

There's nothing."

Keith closed his eyes.  She could be safe, he told himself, she could
have gone through to another exit, she could-- "Tachyon pulse!"  said
Rhombus in what PHANTOM translated as a shout.

Keith swiveled around to look at the shortcut, now swelling into a
purple-limned shape--in the exact cross sectional outline of a
Commonwealth probeship.

"It's the Rum Runner!"  crowed Thor.

"Incoming signal," said Lianne.  She touched keys and a hologram of
Rissa's beaming face appeared inside a floating frame.

"Hello, everyone," said Rissa.  "Fancy meeting you here."

"Pdssa!"  said Keith, rising to his feet.

"Hello, darling," said Rissa, smiling radiantly.

"Rhombus," said Keith, "can they dock with us, given the course we're
on?"

"They can if I give them a tow with a tractor beam."

Keith was grinning widely.  "Please do so!"

"Okay, guys," said Rhombus, "prepare to be grabbed by a tractor."

Longbottle's gray face popped up next to Rissa's.  "Pre- pared are we!

Home we come!"

"Locking on," said Thor.

"Thor," said Keith, "do you have a fix on Cat's Eye?"

"Yes.  He's about ten million klicks ahead, at about nine o'clock to the
green star."

"I've located a vacant frequency in the darmat babble, in case you want
to talk to him," said Lianne.  "Somebody must have left the conversation
recently."

"Excellent," said Keith.  "Keep track of it.  As soon as Rissa's back on
board, I'll want to open communication."

"We'll have the Rum Runner in docking bay seven in about three minutes,"
said Rhombus.

Keith was anxious as hell.  He tried to hide it by checking status
reports on his monitor screens, but his mind wasn't registering the
words.  At last, the' starfield split and Rissa appeared, framed by the
corridor beyond.  Keith ran to her, and they hugged, then kissed.  The
rest of the bridge crew cheered as she entered.  A moment later,
Longbottle popped up in one of the two open pools.  Rissa knelt down
beside him and rubbed his bulging forehead.  "Thanks for getting us home
safe and sound, buddy," she said.

"We're doing a quick parabolic path," Keith said to them.

"I don't think the darmats can grab us this time, but I want to
communicate with them--find out why in the hell they attacked us."

Rissa nodded, stood up, kissed Keith once more, then moved over to her
workstation.  She pressed keys, calling up the translation program.

"Do we still have a vacant frequency?"  asked Keith.

"Yes," said Lianne.

"All right.  Let's jump into the conversation.  Lianne, open a channel
from my console with automatic translation, but put a five-second delay
in before you send whatever I say."

He looked at Rissa.  "I'll speak directly to Cat's Eye, but if I say
anything wrong or something that you don't think will translate
properly, jump in, and we'll reword the message before it goes out."

Rissa nodded.

"Ready," said Lianne.

"Starplex to Cat's Eye," said Keith.  "Starplex to Cat's Eye.  We are
friends.  We are friends."  Keith glanced at a counter.  At light-speed,
it would still be thirty-five seconds before the message reached Cat's
Eye, and almost that long again before any reply would arrive.

But no reply came.  Keith waited an extra full minute, then another.

He touched a key and tried again.  "We are friends."

Finally, after a forty-second delay in addition to the round-trip signal
time, a reply came through.  Just two words, in a curt French accent:
"Not friends."

"Yes," said Keith.  "We are friends."

"Friends not hurt," came the reply, with no delay beyond that caused by
transmission times.

Keith was taken aback.  Had they somehow hurt the darmats?  It was
almost inconceivable that they could injure such giant creatures.

Still .  . . perhaps the sampling probes had caused pain.  Keith didn't
have the slightest idea how to apologize; the vocabulary Rissa had built
up didn't deal with such concepts.

"We did not mean to hurt you," said Keith.

"Not directly," said Cat's Eye.

Keith spread his hands and looked around the bridge.

"Anybody understand that?"

"I think he means whatever injury we caused wasn't a direct injury,"
said Lianne.  "We didn't hurt them, but hurt--or were going to
hurt--something that was important to them."

Keith touched the transmit key.  "We intend no injury to anything.  But
you--you deliberately tried to kill us."

"Make you.  Not make you."

Keith keyed the mike off.  "'Make you.  Not make you,'" he repeated,
shrugging helplessly.  "Anybody?"

Lianne lifted her hands, palms up.  Jag moved all four of his shoulders.

Rhombus's web was dark.

Keith reactivated the mike.  "We want to be friends again."

The response time was getting shorter as Starplex's parabolic course
brought the ship closer to Cat's Eye.  "We want to be friends again,
too," said the darmat., Keith thought for a moment, then: "You say we
injured you somehow.  We did not intend any injury.  So that we don't do
it again, will you tell us what we did wrong?"

The delay time was nerve-racking.  Finally: "Attacking each other."

"You were bothered by the battle?"  asked Keith.

"Yes."

"Worried that explosions would hurt you?"

"No."

"But then why did you fling those ships into the star?"

"Afraid."

"Of what?"

"That your activities would destroy .  . . destroy .  . .

point that is not a point."

"The shortcut?  You were afraid that we would destroy the shortcut?"

"Yes."

"No explosion could damage the shortcut.  It's not fragile."

"Did not know."

Jag barked softly.  "Ask him why he cares."

Keith nodded.  "Why do you care about the shortcut, anyway?  Do you use
it yourselves?"

"Use?  No.  Not use."

"Then why?"

"Spawn."

"They're important to your spawning practices?"

"No, one of our spawn," said the voice from the speaker.

It was frustrating--and probably as much so for the darmat as it was for
Keith.  Cat's Eye was used to being part of a community whose members
had been talking among themselves for millennia.  They understood the
context of each other's remarks, the history.

Explicating a thought in detail was not normal for themeand possibly
even rude.

"One of your spawn," Keith said again, helpfully.

"Yes.  Touched the point that is not a point."

Oh, my God.  "You mean one of your youngsters went through the
shortcut?"

"Yes.  Lost."

"Christ," said Thor, turning around.  "That's what activated this
shortcut--a darmat baby going through!"

Keith leaned back in his chair.  "And if our fighting had accidentally
destroyed the shortcut, your child would never have been able to find
its way home again, right?"

"Rightness abounds.  When you first arrived, we thought you had come to
bring our spawn home."

"You never asked us about that."

"Wrong to ask."

"Darmat bad manners," said Rissa, eyebrows raised.

Keith spread his arms.  "We didn't know about your child.

How long ago did it go through the shortcut?"

"Time since you first arrived, doubled."

Keith turned to his left, looking at Jag.  "The child couldn't have gone
far from the exit point, then.  Any way of knowing which shortcut it
would have come out from?"" "Well," said Jag, "the child must have
emerged through an already active exit.  But, as we found when we went
careening through this shortcut ourselves, there are more active exits
than we were aware of--possibly trillions more, if they permeate
intergalactic space and other galaxies.

And, since the shortcuts rotate, without knowing to the second what time
the child went through, even duplicating the approach angle wouldn't
help us.  The thing could be anywhere."

"But if we could find the child and bring it safely home," said Keith,
"well, not only would that be the right thing to do, it would also help
cement our relationships with the darmats."  He looked around the
bridge.  "Anyone disagree?"

He turned the mike back on.  "Does the child have a name?

A unique identifying word?"

"Yes.  It is"--PHANTOM's own voice replaced the synthesized one coming
through the speaker--"untranslated term."

Keith gestured at PHANTOM's eyes.  "Call it--call it Junior," he said.

"Acknowledged."

Keith looked over at Rhombus, who could see Keith clearly, of course,
even though his backside was to him.

"Rhombus, what do You think?"

"It could be a very steep slope that ends in a cliff," he said--a
wild-goose chase.  "But, as you have said, establishing friendly
relationships is what Starplex is all about.  I say we at least try."

"Should we ask one of them to come with us?"  asked Lianne.

"There is no way we could go through the shortcut together," said Thor,
turning to face her.  "Remember, even the smallest of those beings
masses as much as Jupiter.  And without precisely controlling its
entrance angle, the darmat might end up coming out of a different
shortcut, meaning we'd have two lost darmats, instead of one."

Keith reactivated the mike.  "We will look for your child," he said.

"Would you please call out to it?  We will record that, and play it back
at each possible place it might be.  Call out to it, and ask it to come
with us.  Tell it that we will not hurt it, and that we only want to
guide it home."

"Record?"

"Like an oral history; we will repeat it."

"Doing," said the voice from the speaker.  Keith let the entreaties
spill into PHANTOM's memory.

"We have it," said Keith, once Cat's Eye stopped transmitting.

"Find our child," said Cat's Eye.  "I--words unavailable."

The translation exercises hadn't covered this topic.  But Keith
understood across species lines--across matter lines.

He nodded.
Chapter XXII


Keith was in his office, going over proposals for finding the darmat
baby.  It was the first of the month; the holo on his desk of Rissa had
automatically changed to a pose of her in shorts and tank top, taken
during a hike through the Grand Canyon.  The Emily Carr painting had
switched to an A. Y.

Jackson view of Lake Superior.

"Jag Kandaro em-Pelsh is here," announced PHANTOM.

Keith spoke without looking up from the datapad he was reading.  "Let
him in."

Jag entered and helped himself to a chair.  He had all four arms crossed
in front of his massive chest.  "I want to go get the darmat child," he
barked.

Keith leaned back in his chair and looked at the Waldahud.

"You?"

Jag's dental plates clicked together defiantly.  "I."

Keith breathed out slowly, using the time it took to complete the
exhalation to gather his thoughts.  "This is a delicate mission."

"And you do not trust me anymore," said Jag.  He moved his upper
shoulders.  "I realize that.  But the attack on Starplex was not
authorized by Queen Trath.  And the attack on Tau Ceti that Rissa has
told us about was repulsed.

Matters are at an end rightnow--unless you humans wish to prolong them.

Where do we go from here, Lansing?  Is it over?  Or do we go on
fighting?  I am prepared to act as if--"

"As if nothing had happened?"

"The alternative is war.  I do not want that, and I had believed you did
not want it, either."

"But--"

Jag's barks were sharp.  "The choice is yours.  I have volunteered a
peaceful coexistence.  If you want your--what is the human
metaphor?--your pound of flesh, I refuse to grant it.  But finding the
child and getting it home will require the utmost skill in shortcut
mechanics.  Magnor is good at such matters, but I am better.  Indeed,
there is no one better in all the Commonwealth.  You know this to be
true;

if it were not, I would not be assigned to this ship."

"Thor is trustworthy," said Keith simply.

The Waldahud's two right eyes were already locked on Lansing, and a
moment later the two left ones converged on him as well.  "The choice is
yours.  You have my report."  He gestured at the datapad Keith was still
holding.  "I have suggested we send a probeship to find the child.  I
should be on that ship."

"All you want," said Keith, "is access to the darmats for your people.

Bringing home their child would earn you much gratitude."

Jag moved his lower shoulders.  "You do me a disservice, Lansing.

Indeed, the darmats do not yet know that there are a thousand entities
aboard this ship, let alone that they represent a quarter-sixteen of
races."

Keith thought for a moment.  Damn, he hated being pushed.  But the
bloody pi--but Jag was right.  "Okay," he said.  "Okay--you and
Longbottle, if he's up to it.  Is the Rum Runner in any condition for
another mission?"

"Dr.  Cervantes and Longbottle had it serviced at Grand

Central," said the Waldahud.  "Rhombus has confirmed that it is
spaceworthy."

Keith looked up.  "Intercom: Keith to Thor."

A hologram of Thoraid Magnor's head appeared floating above Keith's
desk.  "Yes, boss?"

"How are we for travel through the shortcut?"

"No problems," said Thor.  "The green star is far enough from it now to
allow just about any entrance angle.  You want me to program a run?"

Keith shook his head.  "Not for the whole ship.  Just for the Rum Runner
and a one-person travel pod.  I'm going to have to return to Grand
Central for a meeting with Premier Kenyatta."  He looked back at the
Waldahud.  "Despite what you just said, Jag, there's going to be hell to
pay."

It was the ultimate grand tour: around the galaxy in twenty shortcuts--a
quick survey of all the active exit points.  The Rum Runner, with Jag
and Longbottle aboard, zoomed away from Starplex's docks and, after
Longbottle's requisite joyride, headed for the shortcut.

As always, the exit point expanded as the ship touched it.

The purple discontinuity moved from bow to stern, and then the ship was
zooming through a different sector of space.

There were no spectacular sights to be seen at this first exit: just
stars, somewhat less densely packed than they had been on the other
side.

Jag was intent on his instruments.  He was doing a hyperspace scan,
looking for any large mass within a light-day of the exit.  Finding the
darmat child would be hard.  Dark matter, by its very nature, was very
difficult to detect--all but invisible, and the radio signals it put out
were very weak indeed.  But even a baby darmat was going to mass 1037
kilograms.  It would make a dent in local spacetime that should be
detectable in hyperspace.

"Anything?"  asked Longbottle.

Jag moved his lower shoulders.

Longbottle arched in his tank, and the Rum Runner' curved back toward
the shortcut.

"Again we go," said the dolphin.  The ship dived toward the point---and
popped out near a beautiful binary star system, streamers of gas flowing
from a bloated, oblate red giant toward a tiny blue companion.

Jag consulted his instruments.  Nothing.  The Rum Runner did a
loop-the-loop and came down upon the shortcut from above, diving
through, a burst of Soderstrom radiation washing over the ship, the
spectacle of the binary pair being replaced by a new starscape, with a
great yellow-and-pink nebula covering half the sky, a pulsar at its
heart cycling dim and bright over a period of a few seconds.

"Nothing," said Jag.

Longbottle arched again, and plunged toward the shortcut.

An expanding point.

A ring of purple.

Mismatched starfields.

Another sector of space.

A sector dominated by another green star pulling away from the shortcut.

Longbottle maneuvered furiously to avoid it.

Jag's scan took longer; the nearby star overwhelmed the hyperspace
scanner.  But, finally, he determined the darmat child was not there.

Longbottle rotated in his tank, and the Rum Runner did a corkscrew
flight back into the shortcut.  When they popped out this time, it was
through Shortcut Prime, near the galactic core, the initial shortcut
that had presumably been activated by the shortcut makers themselves.

The sky blazed with the light of countless tightly packed red suns.

Longbottle nosed a control, and the ship's shields increased to maximum.

They were close enough to the heart of the galaxy to see the comscating
edge of the violet accretion disk surrounding the central black hole.

"Not here," said Jag.

Longbottle maneuvered the ship back to the shortcut in a simple straight
line.  They hadn't been close enough to be caught by the singularity's
ravenous gravity, but he was taking no chances.

They next exited into another seemingly empty region of space, but Jag's
hyperspace scanners indicated the presence of substantial concealed
mass.

"Suppose not do you?"  asked Longbottle.

Jag shrugged all four shoulders.  "It couldn't hurt to check," he said,
adjusting the shipboard radio to search near the twenty-one-centimeter
band.

"Ninety-three separate frequencies currently in use," said Jag.

"Another community of darmats."

They were tens of thousands of light-years from the first darmats they
had encountered, but, then again, the darmat race was billions of years
old.  It was possible that they all spoke the same language.  Jag
scanned the cacophony, found the topmost frequency group, and, since
there were no vacancies, transmitted just above it.  "We are looking for
one called Junior"--the ship's computer substituted the baby's real
name.

There was silence for a lot longer than round-trip message time would
require, but then, finally, a reply did come through.

"No one here by that name.  Who are you?"

"No time to chat--but we'll be back," said Jag, and Longbottle turned
the ship back toward the shortcut.

"Bet surprised them that did," said the dolphin as they passed through
the gateway.

This time they emerged near a planet about the size of Mars, and just as
dry, but yellow rather than red.  Its sun, a blue-white star, was
visible in the distance, about twice the apparent diameter of Sol as
seen from Earth.  "Nothing here," said Jag.

Longbottle allowed himself the luxury of moving the Rum Runner in such a
way that the bulk of the yellow planet precisely eclipsed the star.

The corona--mixing purple and navy and white--was gorgeous, and covered
much more of the sky than the dolphin had expected.  He and Jag basked
in the sight for a moment, then they dived back through the shortcut.

This exit point had also recently had a star emerge from it, but it
wasn't green.  Rather, as at Tau Ceti, this one was a red dwarf, small
and cool.

Jag consulted his scanners.  "Nothing."

They dived through again, the shortcut opening like a purple-lipsticked
mouth to accommodate them.

Pure blackness--no stars at all

"A dust cloud," said Jag, his fur dancing in surprise.

"Interesting--it wasn't here the last time anyone went through to this
exit.  Carbon grains mostly, although there are some complex molecules,
too, including formaldehyde and even some ammo acids, and--Cervantes
will want to return here, I think.  I'm picking up DNA."

"In the cloud?"  asked Longbottle, incredulous.

"In the cloud," said Jag.  "Self-replicating molecules floating free in
space."

"But no darmat, correct?"

"Correct," said Jag.

"A wonder for another time," said Longbottle, and he spun the ship
around, fired retros, and headed back through the shortcut.

A new sector of space--another one that had recently had a star erupt
from it.  This time the intruder was a blue type-O, with more purple
sunspots than a fair-haired human had freckles in summer.  The Rum
Runner had emerged right on the edge of one of the Milky Way's spiral
arms.  To one side, the sky was thick with bright young stars; to the
other, they were sparse.  Overhead, a globular cluster was visible, a
million ancient red suns packed together into a ball.  And-- "Bingo,"
said Jag--or, at least, he barked something that would be translated as
that in English.  "There it is!"

"See do I," agreed Longbottle.  "But .  . ."

"Parched land!"  swore Jag.  "It's trapped."

"Agree--caught in the net."

And indeed it was.  The baby darmat had obviously stumbled out of the
shortcut only a few days before this blue star had arrived, and the star
had been expelled from the exit in approximately the same direction as
the darmat.  As they'd all discovered to their shock, a darmat could
move with surprising agility for a free-floating world, but the gravity
of a star was enormous.  The baby was only forty million kilometers from
its surface--less than Mercury's distance from Sol.

"There is no way it can manage escape velocity," said Jag.  "I'm not
even sure it's managed to settle into orbit; it may be spiraling in.

Either way, though, that darmat is not going anywhere."

"Will signal," said Longbottle--and he set the ship's transmitter to
broadcast the prerecorded message on all the frequencies that the
members of the darmat community had used.

They were about three hundred million kilometers from the star; the
signals took over fifteen minutes to reach the darmat, and the quickest
any reply could be received would be another fifteen minutes after that.

They waited, Jag fidgeting, Longbottle amusing himself by painting a
sonar caricature of Jag as he fidgeted.  But no reply was received.

"Well," said the Waldahud, "there's so much radio noise coming from the
star, we might not be able to pick up the darmat's transmission.  Or it
might not be able to hear us."

"Or," said Longbottle, "darmat may be dead."

Jag made a noise like bubble wrap being burst, his snout vibrating as he
did so.  That was the one possibility he didn't want to consider.

But the heat that close to the star would be incredible.  The side of
the darmat facing it might be.  over 350 degrees Celsius, hot enough to
melt lead.  Neither Jag nor Delacorte had yet worked out all the
particulars of luster-quark meta-chemistry, but many normal complex
molecules broke down when heated that high.

Another thought occurred to Jag.  What, if any, funereal customs would
the darmats have?  Would they want this world-sized corpse brought home?

He glanced at Longbottle.

Dolphins just let the body float away when one of their own died.  Jag
hoped the darmats would be equally sensible.

"Let's head back," said Jag.  "There's nothing we can do on our own."

The Rum Runner zoomed toward the shortcut in one of Longbottle's
patented sweeping curves, hitting the point at the precise angle
required to exit where they'd started all those jumps ago.  Starplex was
there, floating against the night, tinged green by the light of the
fourth-generation star.

Beyond it were the dark-matter beings, tendrils of gas stretching
between them.  The question now was what to do next.  For one brief
moment, Jag sympathized with Lansing.

He wouldn't want to swim the choppy waters of the river that now spread
out before the human.

Keith was in his apartment, preparing to leave for his upcoming meeting
with Premier Kenyatta at Grand Centr.  Station.

An electric bleep sounded.  "Rhombus would like to see you," announced
PHANTOM.  "He requests seven minutes of your time."

Rhombus?  Here?  Keith really felt like being alone just now.  He was
marshaling his thoughts, trying to decide what to say in the meeting.

Still, having an Ib disturb him at home was unusual enough to pique his
curiosity.  "The time is granted," said Keith--the appropriate answer
dictated by Ibese manners.

PHANTOM again: "Since you are going to have an Ib visitor, may I dim the
lights?"

Keith nodded.  The ceiling panels decreased their intensity, and the
glaring white glacier in the wall hologram of Lake Louise turned a muted
gray.  The double-pocket door slid aside and Rhombus rolled in.

Lights flashed on his web.

"Hello, Keith."

"Hello, Rhombus.  What can I do for you?"

"Forgive me for intruding," said the pleasant British voice, "but you
were quite angry on the bridge today."

Keith frowned.  "Sorry if I was harsh," said Keith.  "I'm furious with
Jag--but I shouldn't have taken it out on anyone else."

"Oh, your anger seemed quite focused.  I doubt you gave offense."

Keith lifted his eyebrows.  "Then what's the problem?"

Rhombus was quiet for a moment, then: "Have you ever wondered about the
apparent contradiction my race represents?

We are obsessed, you humans say, with time.  We hate to waste it.  But
we nonetheless spend time on being polite, and, as many humans have
noted, we take pains not to hurt feelings."

Keith nodded.  "I've wondered about that.  Seems that wasting time on
social niceties would take away from more important tasks."

"Precisely," said Rhombus.  "Precisely the way a human would see it.

But we do not perceive it that way at all.  We see getting along as
going--well, our metaphor is 'hub in wheel,' but you'd say 'hand in
hand'--with a philosophy of not wasting time.  A brief but unpleasant
meeting ends up squandering more time than a longer but agreeable one."

"Why?"

"Because after an unpleasant encounter, one spends much time going over
the meeting in one's mind, replaying it again and again, often seething
over the things that were said or done."  He paused.  "You've seen with
Boxcar that under Ibese jurisprudence, we punish direct wastings of
time.  If an Ib wastes ten minutes of my time, the courts may order that
Ib's life shortened by ten minutes.  But did you know that if an Ib
upsets me through rudeness or ingratitude or deliberate maliciousness,
the courts may impose a penalty of sixteen times the amount of time
apparently wasted over the issue?  We use a multiple of sixteen simply
because, like the Waldahudin, that number is the base for our system of
counting; there really is no way to quantify the time actually wasted
mulling over an unpleasant experience.

Years later, painful memories can--again, metaphors fail me.  I would
say 'roll up beside you'; you'd probably say 'rear their ugly head."

It is always better to leave a situation on pleasant terms, without
rancor."

"You're saying we should really put the screws to the Waldahudin?  Get
back sixteen times what they did to us in damages?"  Keith nodded.

"That certainly makes sense."

"No, you miss my meaning--doubtless due to my lack of clarity in
expressing it.  I'm saying forget about what has transpired between you
and Jag, and between Earth and Rehbollo.  I despair over how much of
your mental resources--how much of your time--you humans will waste over
these issues.  No matter how bumpy the terrain, smooth it in your mind."

Rhombus paused for a moment, letting this sink in, then: "Well, I've
used the seven minutes you granted me; I should leave now."  The Ib
began to roll away.

"People have died," said Keith, raising his voice.  "It's not that easy
to smooth it all out."

Rhombus stopped.  "If it is difficult, it is only because you choose for
it to be that way," he said.  "Can you foresee any solution that will
bring the dead back to life?  Any reprisals that won't result in more
people dead?"  Lights played across his web.  "Let it go."

ETA DRACONIS

Glass looked at Keith, and Keith looked at Glass.  Something 'in the
being's manner told Keith this would be their final conversation.

"You mentioned during your introductory speech that your Commonwealth
currently consists of three home-worlds," said Glass.

Keith nodded.  "That's right," he said.  "Earth, Rehbollo, and
Flatland."

Glass tipped his head.  "There are, in fact, only seven thousand worlds
with native life on them in this entire universe at your time--and those
few worlds are spread out over all the billions of galaxies.  The Milky
Way has far more than its fair share: during your time, there are a
total of thirteen intelligent races within it."

"I'll keep score," said Keith, smiling.  "I won't give up until we've
found them all."

Glass shook his head.  "You will find them eventually, of course--when
they're ready to be found.  The shortcuts' facilitating of interstellar
travel isn't just a side effect of their shunting stars back to the
past.  Rather, it's an integral part of the plan.  But so is the safety
valve that keeps sectors of space isolated until their native
inhabitants become starfarers on their own.  Of course, if you have the
appropriate key, as I do, you can travel between any shortcuts, even
apparently dormant ones.  That's important, too, because we shortcut
makers will need to make extensive use of them.  But the way they work
without the key is designed to foster an interstellar community, to give
rise to the kind of peaceful and cooperative future that's in everyone's
interest."

Glass paused, and when he resumed speaking, his tone was a little sad.

"Still, you won't be able to keep score of how many races you have yet
to discover.  When I send you back, I will wipe your memories of the
time you've spent here."

Keith 's heart fluttered.  "Don't do that."

"I'm afraid I must.  We have an isolation policy."

"Do you--do you do this often?  Grab people from the past?"

"Not as a rule, no, but, well, you're a special case.  I'm a special
case."

"In what way?"

"I was one of the first people to become immortal."

"Immortal .  . ."  Keith's voice trailed off.

"Didn't I mention that?  Oh, yes.  You're not just going to live for a
very long time--you're going to live forever."

"Immortal," said Keith again.  He tried to think of a better word, but
couldn't, and so simply said, "Wow."

"But, as I said, you--l--we are a special case of immortality."

"How so ?"

"There are, in fact, only three older human beings than me in the entire
universe.  Apparently, I had a--what do you call it?--an 'in' that got
me the immortality treatments early on."

"Rissa was working on senescence research; I assume she ended up being
codeveloper of the immortality technique."

"Ah, that must have been it," said Glass.

"You don't remember?"

"No--and that's the whole problem.  You see, when they first invented
immortality, it worked by allowing cells to divide an infinite number of
times, instead of succumbing to preprogrammed cell death."

"The Hayflick limit," said Keith, having learned all about it in
conversations with Rissa.

"Pardon ?"

"The Hayflick limit.  The phenomenon that limits the number of times a
cell can divide."

"Ah, yes," said Glass.  "Well, they overcame that.  And they overcame
the old, natural limitation that said you were born with a finite
quantity of brain cells, and that those cells were not normally
replaced.  One of the keys to immortality was to let the brain
constantly create new cells as the old ones wore out, so--"

"So if the cells are replaced," said Keith, eyes growing wide, "then the
memories stored by the original cells get lost."

Glass nodded his smooth head.  "Precisely.  Of course, now we offload
old memories into lepton matrices.  We can remember an infinite amount
of material I don't just have access to millions of books, I actually
remember the contents of millions of books that I've read over the
years.

But I became an immortal before such offloading existed.

My early memories--everything from my first couple of centuries of
life--is gone."

"One of my best friends," said Keith, "is an Ib named Rhombus.  Ibs die
when their early memories get wiped out--new memories overwrite their
basic autonomous routines, killing them."

Glass nodded.  "There's a certain elegance to that," he said.  "It's
very difficult to live without knowing who one is, without remembering
one's own past."

"That's why you were disappointed that I'm only forty-six."

"Exactly.  It means there's still a century and a half of my life that
you can't tell me about.  Perhaps someday, I'll locate another version
of me, from--what would that be?--from about the year 2250 in your
calendar."  He paused.  "Still, you remember the most crucial parts.

You remember my physical childhood, you remember my parents.

Until I spoke to you, I wasn't even sure that I'd had biological
parents.  You remember my first love.  All of that has been gone from me
for so incredibly long.  And yet, those experiences shaped how I behave,
set down the patterns of my personality, the core neural nets of my
mind, the fundamentals of Who I am."  Glass paused.  "I have wondered
for millennia why I act the way I do, why I sometimes torture myself
with unpleasant thoughts, why I interact with others as a bridge-builder
or a peace maker, why I internalize my feelings.  And you have told me:
I was once, long ago, an unhappy child, a middle child, a stoic child.

There had been a horizon in my past, a curve beyond which I could not
see.  You have taken that away.  What you have given me is beyond
price."  Glass paused, then his tone grew lighter.  "I thank you from
the bottom of my infinitely regenerating heart."

Keith laughed, like a yelping seal, and the other Keith laughed too,
like wind chimes, and then they both laughed at the sound the other had
made.

"I'm afraid it's time for you to go home," said Glass.

Keith nodded.

Glass was silent for a moment, then: "I have refrained from giving you
advice, Keith.  It is not my place to do so, and, frankly, there are ten
billion years between us.  We are, in many ways, different people.

What is right for me, now, at this stage of life, may not be right for
you.  But I owe you--for what you have given me, I owe you enormously,
and I would like to repay you with a small suggestion."

Keith tilted his head, waited.

Glass spread his transparent arms.  "I have seen the ebb and tide of
human sexual morality over the eons, Keith.  I've seen sex given as
freely as a smile, and I've seen it guarded as though it were more
precious than peace.  I've known people who have been celibate for a
billion years, 'and I've know others have had more than a million
partners.  I've seen sex between members of different species from the
same world, and between those who evolved on different worlds.  Some
people I know have removed their genitals altogether to avoid the issue
of sex.  Others have become true hermaphrodites, capable of procreative
sex with themselves.

Others still have switched genders--I have a friend who changes from
male to female every thousand years, like clockwork.  There have been
times when humans have embraced homosexuality, and heterosexuality, and
incest, and multiple concurrent spouses, and prostitution, and
bestiality, and sadomasochism, and there have been times when all of
those have been abjured.  I have seen marriage contracts with expiration
dates, and I have seen marriages last five billion years.

And you, my friend, will live long enough to see all these things, too.

But through all of it, there is one constant for people of conscience,
for people like you and me: if you hurt someone you care about, there is
guilt."

Glass dipped his head.  "I do not remember Clarissa.  I do not remember
her at all.  I have no idea what happened to her.  If she, too, became
an immortal, then perhaps she still exists, and perhaps I can find her.

I have loved a thousand other humans over the years; a paltry number by
many people's standards, but sufficient for me.  But there is no doubt
that Rissa must have been very, very special to us; that's apparent in
the way you speak of her."

Glass paused, and Keith had the eerie feeling that eyes--invisible in
that smooth transparent egg of a head--were seeking out his own, seeking
the truth behind them.  "I can read you, Keith.  When you told me
earlier to move along, to pick another topic, it was obvious what you
were hiding, what you have been contemplating."  A beat of silence; even
the forest simulacrum around them held its peace.  "Don't hurt her,
Keith.  You will only hurt yourself."

"That's the advice?"  asked Keith.

Glass lifted his shoulders slightly.  "That's it."

Keith was quiet for a time.  Then: "How will I remember that?  You said
you were going to wipe my memories of this meeting."

"I will leave that thought intact.  You will indeed have no memory of
me, and you'll just think it came from yourself--which, of course, it
did, in a way."

Keith thought for a time about what the appropriate reply was.

Finally, he said, "Thank you."

Glass nodded.  And then, sadly, he said, "It's time for you to go."

There was an awkward moment during which they stood and looked at each
other.  'Keith started to extend his hand, but then let it drop to his
side.  Then, after a second of hesitation, he surged forward, and hugged
Glass.  To his astonishment, the transparent man felt soft and warm. The
embrace lasted only a few seconds.

"Perhaps someday we'll meet again," said Keith, taking a step back now.

"If you ever feel like popping through to the twenty-first century for a
visit .  . ."

"Perhaps I will.  We are about to start something very, very big here.

I told you at the outset that the fate of the universe is in question,
and I--meaning you, too, of course--have a key role to play in that.  I
gave up being a sociologist ages ago.  As you might guess, I've had
thousands of careers over the millennia, and now I'm a--a physicist, you
might call it.  My new work will eventually necessitate a trip to the
past."

"Just remember our full name, for God's sake," said Keith.  "I'm listed
in the Commonwealth directory, but you'll never find me again if you
forget."

"No," said Glass.  "This time I promise I will not forget you, or the
parts of our past you have shared with me."  He paused.  "Good-bye, my
friend."

The forest simulation, along with its motionless sun, daytime moon, and
four-leaf lucky clovers, melted away, revealing the cubic interior of
the docking bay.  Keith started walking toward his travel pod.

Glass stood motionless in the bay as it opened to space.

More magic; he needed no space suit.  Keith touched a key, and his pod
moved out into the night, the six-fingered pink nebula that had once
been Sol staining the sky on his left, the robin 's-egg-blue dragon
receding behind him.  He flew the pod toward the invisible point of the
shortcut, and as he made contact, he felt a faint itching inside his
skull.  He had just been thinking about--about something .  . .

It was gone now, whatever it had been.

Oh, well.  The ring of Soderstrom radiation passed over the pod from bow
to stern, and Keith 's view was filled with the sky of Tau Ceti, Grand
Central Station visible off to his right, looking odd in the dim red
light from the newly arrived dwarf star.

As he always did when he came here, Keith amused himself for a few
seconds finding Boetes, then locating Sol.

He nodded once and smiled.  Always good to know that the old girl hadn't
gone nova .  . .

Chapter XXIII

Keith had always thought Grand Central Station looked like four dinner
plates arranged in a square, but today, for some reason, it reminded him
of a four-leaf clover floating against the stars.  Each of the leaves or
plates was a kilometer in diameter and eighty meters thick, making the
station the largest manufactured structure in Commonwealth space.

Like Starplex's own much-smaller central disk, the outward facing edges
of the plates were studded with docking-bay doors, many of them bearing
the logos of Earth-based trading corporations.  The computer aboard
Keith's travel pod received docking instructions from Grand Central's
traffic controller, and flew him in toward a docking ring adjacent to a
large corrugated space door bearing the yellow-script symbol of the
Hudson's Bay Company, now in its fifth century of operation.

Keith looked around through the travel pod's transparent hull.  Dead
ships were floating across the sky.  Tugs were arriving at the docking
bays hauling wreckage.  One of the station's four plates was completely
dark, as if it had taken a major hit during the battle.

Once his pod was secured, Keith exited into the station.

Unlike Starplex, which was a Commonwealth facility, Grand Central belong
entirely to the peoples of Earth, and its common environment was kept
precisely at terrestrial standard.

A governmental aide was waiting to greet Keith.  He had a broken arm.

It likely occurred during the battle with the Waldahudin, since the
bone-knitting web he had on would normally only be worn for seventy-two
hours after the injury.  The aide took him to the opulent office of
Petra Kenyatta, Human Government Premier of Tau Ceti province.

Kenyatta, an African woman of about fifty, rose to great Keith.

"Hello, Dr.  Lansing," she said, extending her right hand.

Keith shook it.  Her grip was firm, almost painfully so.

"Ma' am."

"Please, have a seat."

"Thank you."  No sooner had Keith sat down in the chair-- a regular,
nonmorphing human chair--than the door slid open again and another woman
came in, this one Nordic in appearance and a little younger than
Kenyatta.

"Do you know Commissioner Amundsen?"  said the premier.  "She's in
charge of the United Nations police forces here at Tau Ceti."

Keith half rose from his chair.  "Commissioner."

"Of course," said Amundsen, taking a seat herself, "'police forces' is a
euphemism.  We call it that for alien ears."

Keith felt his stomach knotting.

"Reinforcements are already on their way from Sol and Epsilon Indi,"
said Amundsen.  "We'll be ready to move on Rehbollo as soon as they
arrive."

"Move on Rehbollo?"  said Keith, shocked.

"That's right," said the commissioner.  "We're going to kick those
bloody pigs halfway to Andromeda?"

Keith shook his head.  "But surely it's over.  A sneak attack only works
once.  They're not going to be coming back."

"This way we make sure of that," said Kenyatta.

"The United Nations can't have agreed to this," said Keith.

"Not the United Nations, of course," said Amundsen.

"Dolphins don't have the spine for something like this.  But we're sure
the HuGo will vote for it."

Keith turned to Kenyatta.  "It would be a mistake to let this escalate,
Premier.  The Waldahudin know how to destroy a shortcut."

Amundsen's sapphire eyes Went wide.  "Say that again."

"They could cut us off from the rest of the galaxy--and they only need
to get one ship through to Tau Ceti to do that."

"What's the technique?

"I--I have no idea.  But I'm assured it works."

"All the more reason to destroy them," said Kenyatta.

"How did they sneak up on you?"  asked Commissioner Amundsen.  "Here at
Tau Ceti, they sent one large mother-ship through, and it disgorged
fighters as soon as it arrived.

I understand from what Dr. Cervantes said while she was here that they
sent individual craft after Starplex.  How was it that you didn't notice
when the first one arrived?"

"The newly emerged star was between us and the shortcut."

"Who ordered the ship to take that position?"  asked Amundsen.

Keith paused.  "I did.  I give all the orders aboard Starplex.

We were engaged in astronomical research, and had to move the ship away
from the shortcut to facilitate that.  I take full responsibility."

"No need to Worry," said Amundsen, grinning like a skull.  "We'll make
the pigs pay."

"Don't call them that," said Keith, surprising himself.

"What?"

"Don't call them that name.  They are Waldahudin."  He managed to say
the word as a bark, with perfect accent and asperity.

Amundsen was taken aback.  "Do you know what they call us?"  she asked.

Keith shook his head slightly.

"Gargtelkin," she said.  "'Ones who copulate out of season.""

Keith suppressed a grin.  But then he sobered.  "We can't go to war with
them."

"They started it."

He thought of his older sister and younger brother.  He thought of an
old black-and-white movie with dueling anthems, the Marseillaise
drowning out Wacht am Rhein.

And he thought most of all of the sight of the young Milky Way, cupped
in his outstretched hand.

"No," said Keith simply.

"What do you mean, 'no'?"  snapped Amundsen.  "They did start it."

"I mean it doesn't make any difference.  None of it does.

There are beings out there made of dark matter.  There are shortcuts in
intergalactic space.  There are stars coming back from the future.  And
you're worried about who started it?  It doesn't matter.  Let's end it.

Let's end it here and now."

"That's exactly what we're talking about," said Premier Kenyatta:
"Ending it once and for all.  Knocking the pigs on their hairy asses."

Keith shook his head.  Midlife crisis--for all of them, humans and
Waldahudin.  "Let me go to Rehbollo.  Let me talk to Queen Pelsh.  I'm
supposed to be a diplomat.  Let me go and talk peace.  Let me build a
bridge."

"People have died," said Amundsen.  "Here at TaU Ceti, humans beings
have died."

Keith thought of Saul Ben-Abraham.  Not the horrid picture that usually
came to mind, Saul's skull opening like a red flower in front of his
eyes, but rather Saul alive, great wide grin splitting his dark beard, a
home-brewed beer in hand.  Saul Ben-Abraham had never wanted war.

He'd gone to the alien ship looking for peace, for friendship.

And what about the other Saul?  Saul Lansing-Cervantes--unable to carry
a tune, sporting a silly goatee, shortstop on one of Harvard's campus
baseball teams, a chocoholic--and a physics major, the kind they would
draft to be a hyperdrive pilot if it came to war.

"Humans have died before, and we have not sought vengeance," said Keith.

Rhombus had been right.  Let it go, he'd said.  Let it all go.

Keith felt it leaving him, the unpleasant thing he'd carried around for:
eighteen years.  He looked at the two women.  "For the sake of those who
have died--and for all those who would die in a war--we have to put out
the fire before it's too late."

Keith reboarded his travel pod, left Grand Central, and headed back
toward the shortcut.

He had spent hours arguing with Commissioner Amundsen and Premier
Kenyatta.  But he wouldn't give up.  This was the windmill he'd been
looking for.  This was the battle worth fighting--the battle for peace.

An impossible dream?

He thought of his great-great-grandfather's wonder-filled life.  Cars
and airplanes, lasers and moon landings.

And his own wonder-filled life.

And all the wonders yet to come.

Nothing was impossible--not even peace.  Any sufficiently advanced
technology is indistinguishable from magic.

Sufficiently advanced.  Races did grow up, did enter a state of
maturity..He was ready for that.  At last, he was ready.

Others must be, too.

Borman, Lovell, and Anders had cupped the Earth in their hands.  Just a
quarter of a century later, that same world had begun disarming itself.

Einstein hadn't lived to see it, but his impossible dream of putting his
nuclear genie back in the bottle had come to pass.

And now humans and Waldahudin had both cupped the galaxy in their hands.

A galaxy that Keith, and surely others, would live to see rotate around
its axis time and again.

There would be peace between the races.  He would make sure of that.

After all, what better job was there for a middle child with billions of
years to spend?

Keith's travel pod touched the shortcut, the purple halo passed over the
spherical hull, and he emerged back near the green star.

Starplex was up ahead, a giant silver-and-copper diamond against the
starry backdrop.  Keith could see that docking bay seven's space door
was open, and the bronze wedge of the Rum Runner was in the process of
landing--meaning Jag and Longbottle must be returning with news of their
search for the darmat baby.  Heart pounding, Keith activated his pod's
preprogrammed docking sequence.

Keith hurried to the bridge.  Although he'd only been gone a short time,
he felt a need to hug Rissa, who happened to be there using her console
even though it was delta shift.  He held her tight for several seconds,
feeling the warmth of her.

Wineglass politely rolled away from the director's workstation in case
Keith wished to use it, but Keith motioned for the Ib to return to it,
and Keith took a chair in the seating gallery at the back of the room.

No sooner had he done so than the forward bridge door opened and Jag
waddled in.  "The baby is trapped," he barked as he made his way over to
the physics station, which was currently unoccupied.  "It's stuck in
close orbit around a star that emerged from the same shortcut the baby
did."

"Did you call out to by radio?"  asked Rissa.  "Any response?"

"None," said Jag, "but the star is a real noisemaker.  Our message might
have been lost going in, or the reply might have been lost coming out."

"It would be like trying to hear a whisper during a hurricane," said
Keith, shaking his head.  "All but impossible."

"Especially," said Longbottle, popping up in the starboard pool on the
bridge, "if the darmat is dead."

Keith looked at the dolphin's face, then nodded.  "That's a good point.

How do we tell if something like that is still alive?

Rissa frowned.  "None of us would survive five seconds close to a star
without a lot of shielding or heavy-duty force screens.  The baby is
naked."

"it's worse than that," said Jag.  "The thing is black.

Although the luster-quark matter is transparent to electromagnetic
radiation, the regular-matter dust that permeates it is not reflecting
any appreciable amount of the star's light and heat.  The child may be
cooking itself."

"So what do we do?"  asked Keith.

"First," said Jag, "we should get it into the shade--build a reflective
foil parasol that could be jockeyed in between the darmat and the star."

"Can our nanotech tab do that here?"  asked Keith.

"Ordinarily, I'd have New Beijing build such a thing and shunt it
through the Tau Ceti shortcut to us, .but I saw the mess they were in
when I popped back for my meeting."

There was a young Native American sitting at InOps.  "I'd have to check
with Lianne to be sure," he said, "but I suspect we can pull it off.

It won't be easy, though.  The parasol will have to be over a hundred
thousand klicks wide.

Even at just one molecule of thickness, that's still a lot of
material."'

"Get to work on it," said Keith.  "How long?"

"Six hours if we're lucky," said the man.  "Twelve if we're not."

"But even if we shield the baby, then what?"  asked Rissa.

"It's still trapped."

Keith looked at Jag.  "Could we use the parasol as a solar sail, and let
the solar wind blow it away from the star?"

Jag snorted.  "Ten to the thirty-seventh kilos?  Not a chance,"

"Okay, okay--what about this?"  said Keith.  "What if we protect the
baby with some sort of force shield, and then detonate the star, so that
it goes nova, and--"

Jag was barking in a staccato pattern--Waldahud laughter.

"Your imagination is unbridled, Lansing.  Oh, there has been some
theoretical work on controlled nova reactions--I've been exploring that
area a bit myself--but there's no shield we could build that would
prOtect the baby from a star going nova only forty million kilometers
away."

Keith was not to be deterred.  "Okay, try this: Suppose we force the new
star back through the shortcut.  When it passes through the shortcut,
its gravitational pull will disappear, and the baby goes free."

"The star is moving away from the shortcut, not toward it," said Jag.

"We cannot move the shortcut at all, and if we had the power to turn a
star around, we would also have the power to skim a Jupiter-sized object
out of a close orbit around the star.  But we don't."  Jag looked around
the room.

"Any more bright ideas?"

"Yes," said Keith, after a moment.  He looked directly at Jag.  "Yes,
indeed!"

When Keith had finished talking, Jag's mouth hung open for a few
moments, showing the two curving blue-white translucent dental plates
within.  Finally, he barked in a subdued fashion.  "I--I know I said
such things were possible, but it has never been tried on anything
approaching this scale."

Keith nodded.  "Understood.  But unless you have a better suggestion--"

"Well," said Jag's Brooklynite voice, "we could leave the darmat baby in
orbit around the star.  Assuming it is still alive, once we put the
parasol sun-shield in place, it could, in theory, live out the rest of
its natural life--however long that isin close orbit around that star.

But if your plan does not work, the darmatchild will be killed."

Jag's voice became quieter.  "I know, Lansing, that I am the one always
looking for glory--and, since my role in what you propose is pivotal, I
have no doubt that considerable glory would accrue to me were we able to
pull this off.  But it really is not our decision to make.

Ordinarily, I'd say ask the--the patient--for permission before
attempting something as risky as this, but that is not possible in this
case, because of the radio noise.  And so I suggest we do what both your
race and mine would do in such circumstances: we should ask the next of
kin."

Keith thought about that, then began to nod slowly.

"You're right, of course.  I keep seeing the macro-issue, that if we
pull this off, it'll be great for our relationships with the darmats.

Damn, sometimes I'm pretty pigheaded."

"That is all right," said Jag lightly, choosing not to take offense at
Keith's unfortunate choice of words.  "Rumor has it that you are going
to have a very long time to acquire more wisdom."

Keith spoke into the mike.  "Starplex to Cat's Eye.  Starplex to Cat's
Eye."

The incongruous French accent; Keith half expected the thing to say
bonjour.  "Hello, Starplex.  It is wrong to ask, but .  . ."

Keith smiled.  "Yes, we have news of your child.  We have located it.

But it is in close orbit around a blue star.  It is unable to get away
under its own power."

"Bad," said Cat's Eye.  "Bad."

Keith nodded.  "But we have a plan that may--I repeat, may--allow us to
rescue the child."

"Good," said Cat's eye.

"The plan involves much risk."

"Quantify."

Keith looked at Jag, who lifted all four shoulders.  "I can't," said the
human.  "We've never done anything like this on this scale before.

Indeed, I only recently learned that it was theoretically possible.  It
may work, or it may not--and I have no way of knowing the likelihood of
either outcome."

"Better idea available?"

"No.  No, in fact, this is our only idea."

"Describe plan."

Keith did so, at least as much as the limited vocabulary they had
established allowed.

"Difficult," said Cat's Eye.

"Yes."

There was a long period of silence on the frequency used by Cat's Eye,
but lots of traffic on the other channels--the darmat community
discussing its options.

At last, Cat's Eye spoke again.  "Try, but .  . . but .  . .

two hundred and eighteen minus one is much less than two hundred and
seventeen."

Keith swallowed.  "I know."

The PDQ (containing the cetacean physicist Melondent) and the Rum Runner
(with Jag and Longbottle aboard) headed through the shortcut .to the
sector containing the darmat baby.  Working in tandem, the two ships
deployed the molecule-thick parasol.  Reaction motors were mounted on
the parasol's frame, firing away from the blue star to keep the solar
wind from blowing it away.  Once the baby was in the shade, its nearside
surface temperature began to drop rapidly.

Next, 112 hastily constructed buoys, each consisting of a hollowed-out
watson casing with special equipment mounted inside, were popped through
the shortcut from Starplex.  The two probeships used their tractor beams
to array them in interlocking orbits around the baby.

On one of his tall, thin monitor screens aboard the Rum Runner, Jag
displayed a hyperspatial map showing the steep local gravity well with
the star at the bottom.  The sides of the well were almost perpendicular
this close to the star; they only began to flare out just before the
orbiting darmat was encountered.  The baby made a second, smaller well
of its own.

Once the buoys were in place, the PDQ headed off, moving past the
shortcut without going through it, and continuing on for half a day.

Finally, they were all lined up in a neat row.  At one end was the Rum
Runner.  Next to it was the darmat baby.  Forty million kilometers
beyond the baby was the fiery blue star.  Three hundred million
kilometers farther on was the shortcut, and a billion kilometers beyond
that was the PDQ--Melondent was now a total of seventy-two light-minutes
from the star, far enough away that her local space was now reasonably
flat.

"Ready?"  barked Jag to Longbottle, in the Rum Runner's piloting tank.

"Ready," the dolphin barked back in Waldahudar.

Jag touched a control, and the lattice of buoys surrounding the darmat
baby sprang to life.  Each buoy contained an artificial-gravity
generator, powered by solar energy stolen from the very star they were
trying to fight.  Slowly, in unison, the buoys increased their output,
and just as slowly, a flattening pocket began to develop in one wall of
the star's steep gravity well.

"Gently," said Jag, under his breath, watching his hyperspace map.

"Gently."

The pocket continued to grow more and more flat.  Great care had to be
taken not to flatten out the darmat's own gravity well: if the effects
of the baby's own mass were suppressed--which, after all, was what was
holding it together--it would lose cohesion, and expand like a balloon.

The buoys' output continued to grow and the curvature of spacetime
continued to diminish, until, until-- Flatness, like a plateau jutting
from the side of the well.

It was as if the darmat were in interstellar space, not spitting
distance from a star.

"Isolation complete," said Jag.  "Now let's get it out of there."

"Activating hyperdrives," said Longbottle.

The antigrav buoys made up points on a sphere around the baby, but now,
as their individual hyperspace field generators came on, that whole
sphere seemed to mirror over, as if it were a glob of mercury floating
freely in space.

In a matter of seconds, the glob shrank to nothingness and disappeared.

The buoys were preprogrammed to move the darmat baby away from the blue
star as fast as possible.  The PDQ was waiting near the point at which
the darmat should emerge from hyperspace, far enough from the star that
the hyper-drive field should collapse without difficulty.

The Rum Runner set out for the same location, traveling under thruster
power.  As they passed near the shortcut point, a radio message from
Melondent came through, blueshifted because of the Rum Runner's
acceleration toward her ship.

"PDQ to Longbottle and Jag.  Arrived has darmat baby; popped into normal
space it did right in front of my eyes.

Hyperdrive field collapse uneventful was.  But baby shows still no signs
of life, and responds does not to my hails."

Jag's fur moved pensively.  No one had known for sure whether the baby
would survive unprotected during its brief journey through hyperspace.

Even if it had been alive beforehand, that might have killed it.

Maddeningly, there was no way to tell.

The space-flattening technique Was risky.  Rather than use it themselves
so that Longbottle could engage the Rum Runner's hyperdrive, they flew
out to their rendezvous with the PDQ under thruster power.

To fill the time, and to get his mind off of the fate of the baby, Jag
spoke with Longbottle, who, to his credit, was piloting the ship in an
absolutely straight line.

"You dolphins," said Jag, "like the humans."

"Mostly," said Longbottle in high-pitched Waldahudar.

He let the piloting drones disengage from his fins, and put the ship on
automatic.

"Why?"  barked Jag sharply.  "I have read Earth history.

They polluted the oceans you swam in, captured you and put you in tanks,
caught you in fishing nets."

"No one of them has done any of that to me," said Longbottle.

"No, but--"

"It is the difference: we generalize do not.  Specific bad humans did
specific bad things; those humans do we not like.  But the rest of
humanity we judge one by one."

"But surely once they discovered you were intelligent, they should have
treated you better."

"Humans discovered intelligent we were before we discovered that
they-were."

"What?"  said Jag.  "But surely it was obvious.  They had built cities
and roads, and--"

"Saw none of that."

"No, I suppose not.  But they sailed in boats, they built nets, they
wore clothes."

"None of those were meaningful to us.  We had of such things no concept;
nothing to compare them to.  Mollusk grows a shell; humans have clothes
of fabric.  The mollusk's covering is stronger.  Should judged we have
the mollusk more intelligent?  You say humans built things.  We had no
concept of building.  We knew not they made the boats.  We thought
perhaps boats alive were, or had once been alive.

Some tasted like driftwood, others ejected chemicals.  into the water,
just as living things do.  An achievement, to ride on the back of boats?

We thought humans were like remoras to the shark."

"But--"

They our intelligence did not see.  They looked right at us and see it
did not.  And we looked at them and did not see theirs."

"But after you discovered their intelligence, and they yours, you must
have realized they had been mistreating you."

"Yes, some in the past mistreated us.  Humans do generalize, they blamed
themselves.  Learned have I since that concept of ancestral
guilt--original sin--is to many of their beliefs central.  There were
cases in human court to determine compensation due to dolphins.  This
made to us no sense."

"But you get along with humans now, which is something my people are
having trouble managing.  How do you do it?"

Longbottle barked, "Accept their weaknesses, welcome their strengths."

Jag was silent.

Finally, the Rum Runner reached its destination, 1.3 billion kilometers
from the star, and a billion kilometers past the shortcut.  Jag and
Melondent consulted by radio about the exact trajectory they wanted to
launch the darmat child on, then the gravitational buoys were activated
again, pushing and pulling the world-sized being, which, as planned,
started to fall in toward the star, sliding back down the gravity well
it had earlier been whisked out of.  But this time, the shortcut point
was in between the darmat and the star; this time, if all went well, the
Child would touch the shortcut, its approach to it speeded somewhat by
the attraction of the star's gravity beyond.

Even at full thrusters, it took more than a day for the buoys to bring
the darmat back in to the vicinity of the shortcut.  Melondent popped a
watson through to Starplex, warning them that, if all went well, the
baby was about to reemerge on their side.

When they did get close to the shortcut, the buoys fought to slow down
the baby's speed so that it would pass slowly through the portal.  The
whole-rescue effort would be for naught if the darmat ended up whipping
in toward the green star near Starplex.  Once it had been braked to a
reasonable speed, they adjusted the baby's trajectory so that it would
pass through the tachyon sphere on the precise course required.

First to pass through the shortcut were some Of the gravity buoys,
then, at last, the baby itself touched it.  The point began to swell,
widening, enveloping the darmat, lips of purple lightning surrounding,
then engulfing, the giant black sphere.  Jag wondered what was going
through the darmat's mind during the passage, assuming it was still
alive.

And if it was alive, and did at some point regain whatever passed for
consciousness, then, Jag wondered, what if it panicked?  What if it was
unable to make sense out of being partly in one sector of space and
partly in another?  It might grind its own passage to a halt.  If the
beast were to expire there, halfway through the shortcut, there might be
no way to dislodge it.  The shortcut opening formed a tight seal around
the passing body, so no coordination of the use of gravity generators on
both sides would be possible.  And that would mean that the Rum Runner
and the PDQ might be trapped forever here, out on the edge of the
Perseus arm, tens of thousands of light-years from any of the
home-worlds.

The darmat was deforming a bit as it moved through the opening, the
shortcut's periphery clamping down on it.  Such clamping was normal, and
the effect on rigid spaceships was negligible, but the darmat was mostly
gas--exotic, luster-quark gas to be sure, but still gas.  Jag feared the
baby would be cleaved in two--similar to the normal birthing process,
but possibly fatal when done unexpectedly.  But it seemed the creamre's
core was sufficiently solid to prevent the shortcut from pinching all
the way through.

At .last, the darmat completed its passage.  The shortcut collapsed down
to its normal dimensionless existence.  Jag wanted Longbottle to
immediately dive through the shortcut so that they could see the result
of all their efforts.  But they, and Melondent aboard the PDQ; had to
wait for hours to be sure the darmat had moved far enough from the
shortcut so that a collision--or just tidal stress from its enormous
gravity--wouldn't destroy their ships when they popped through to the
other side.

At last, after a probe had indicated it was safe to go through,
Longbottle programmed the computer to take them home.  The Rum Runner
moved forward.  The shortcut swelled, and they passed through to the
other side.

It took Jag a few moments to take in all that he was seeing.  The baby
was there, all right.  And so was Starplex.

But Starplex was surrounded on all sides by darmats, and the ship itself
looked dead, all the lights in its windows dark.

Chapter XXIV

The shortcut point began to expand, starting as a violet pinprick of
Soderstrom radiation, and growing as an ever-expanding purple ring.

First to pop through was one of Starplex's hastily constructed
antigravity buoys, and then another and another.  They zoomed across the
sky like bullets.  They'd been tugging the darmat baby, but since they
came through the portal before it did, they were severed from its mass
and so shot ahead.  Soon, though, the bulk of the darmat baby began its
passage, bulging out through the ring of purple in the sky.

On Starplex's bridge Thoraid Magnor let loose a great cheer, and it was
echoed by hundreds of others from all over the ship, as everyone watched
the spectacle either through a window or on a viewscreen.

Cat's Eye and a dozen other adult darmats moved closer to the shortcut,
calling out to the baby.  Over the bridge speakers, PHANTOM played a
translation of what Cat's

Eye was saying, but many of the words were missing; the leader of the
darmats was not limiting his vocabulary to the few hundred words Rissa
and Hek had learned.  "Come forward... forward... toward..  you are...

we...

come... hurry... do not... forward... forward "

Rhombus was using the deck-one array to monitor the emerging baby, but
so far it hadn't transmitted a word of its own, at least not on any
frequency even close to the twenty-one-centimeter band.

Lianne Karendaughter was shaking her head.  "It's not moving at all
under its own volition," she said.  "It must be dead."

Keith ground his teeth together.  If it was dead, all this was for
nothing-- "It's possible," he said, at last, trying as much to convince
himself as Lianne, "that a single darmat can't move on its own.  They
may need to play off each other's gravity and repulsion.  The baby may
not yet be far enough out for that."

"Forward," said Cat's Eye.  "Forward .  . come .  . you .  . .

forward."

Keith had never heard of anyone trying so slow a passage through a
shortcut before--there was an unspoken sense that one should hurry
through, that to tarry would be tempting fate, lest the magic of the
thing fail.

At last the baby completed its passage.  The shortcut collapsed,
although, moments later, it opened slightly several times as additional
antigrav buoys popped through from the other side.

The darmat child was moving away from the shortcut, but only under
momentum.  It had not yet-"Where...

where..."

Still a French-accented voice, but, in a stroke of rare creativity,
PHANTOM had chosen a child's tones for this translation.

"Home .  . back .  . ."

Thor let loose another thunderous cheer.  "It's alive!"

Keith found his eyes misting over.  Lianne was openly crying.

"It's alive!"  Thor shouted again.

The darmat baby did, finally, begin to move, heading toward Cat's Eye
and the others.

The speakers changed back to the voice PHANTOM had assigned to Cat's
Eye.  "Cat's Eye to Starplex," it said.

Keith keyed his mike.  "Starplex responding," he said.

Cat's Eye was quiet longer than the round-trip signal time would have
required, as if he was searching for a way to express what he wanted to
say using the limited vocabulary available.  Finally, simply, he said,
"We are friends."

Keith felt himself grinning from ear to ear.  "Yes," he said.

"We are friends."

"The child's vision is damaged," said Cat's Eye.  "It will .  . .

become equal to one again, but time is required.

Time, and absence of light.  Green star is bright; not here when child
left."

Keith nodded.  "We can build another shield, to protect the baby from
the green star's light."

"More," said Cat's Eye.  "You."

Keith was momentarily puzzled.  "Oh--of course.  Li-anne, kill all our
running lights, and, after warning people, douse the lights in all rooms
with windows.  If people want to put their lights back on, tell them to
draw the shades first."

Lianne's beautiful face was split by a wide smile.  "Doing

SO."

Starplex went dark, and the darmat community moved toward the great ship
and their newly returned child.

The Rum Runner popped through the shortcut, followed moments later by
the PDQ.  Radio communication soon assured their crews that Starplex was
all right, and the ships curved in toward the docking bays.  As soon as
the Rum Runner was safely aboard, Jag headed for the bridge.

Keith was still talking to Cat's Eye when Jag entered the bridge.  The
director turned to the Waldahud.  'qhank you, Jag.  Thank you very
much."

Jag nodded his head, accepting the comment.

The voice of Cat's Eye came over the speakers.  "We to you an
incorrect," he said.

A wrong, thought Keith.  They did us wrong.

"You into point that is not a point had to move with high speed."

"Oh, it wasn't so bad," said Keith, ever the diplomat, into the mike.

"Because of that we got to see our group of hundreds of millions of
stars."

"We call such a group a"--PHANTOM translated the new signal--" galaxy."

"You have a word for galaxy?"  said Keith, surprised.

"Correct.  Many stars, isolated."

"Right," said Keith.  "Well, the shortcut put us six billion light-years
from here.  That meant we were seeing our galaxy as it looked six
billion years ago."

"Understand looking back."

"You do?"

"Do."

Keith was impressed.  "Well, it was fascinating.  Six billion years ago,
the Milky Way didn't have its current shape.  Um, I guess you don't
know this, but it's currently shaped like a spiral."  A light flashed on
Keith's console, PHANTOM notifying him that he'd just used a word for
which there was as yet no darmat equivalent in the translation database.

Keith nodded at PHANTOM's cameras.  "A spiral," he said into the mike,
"is .  . . is .  . . "He sought a metaphor that would be meaningful;
terms such as "pinwheels" would convey no information m the darmat.  "A
spiral is .  . ."

PHANTOM provided a definition on one of Keith's monitor screens.  He
read it into the mike.  "A spiral is the path made by an object rotating
around a central point while also receding from that point at a constant
speed."

"Understand spiral."

"Well, the Milky Way is a spiral, with four major"--he wanted to say
"arms," but again that was a useless word--"parts."

"Know this."

"You do?"

"Made."

Keith looked at Jag, who moved his lower shoulders up and down in a
shrug.  What did the darmat mean?  That he'd been made to learn this
fact in some dark-matter equivalent of grammar school?

"Made?"  repeated Keith.

"Once plain, now .  . now .  . . no word," said the darmat.

Lianne spoke up.  "Now pretty," she said.  "That's the word he's looking
for, I bet."

"To look at it, one plus one greater than two?"  asked Keith into the
mike.

"Greater than.  More than sum of its parts.  Spiral is .  . ."

"Is pretty," said Keith.  "More than the sum of its parts, visually."

"Yes," said Cat's Eye.  "Pretty.  Spiral.  Pretty."

Keith nodded.  There was no doubt that spiral galaxies were more
interesting to look at than elliptical ones.  Keith was pleased that
humans and darmats apparently shared some notion of aesthetics, too.

Not too surprising, though, .given that many artistic principles were
based on mathematics.

"Yes," said Keith.  "Spirals are very pretty."

"That why we make them," said the synthesized voice from the speaker.

Keith felt his heart jump, and he saw Jag do a reflexive splaying of all
sixteen of his fingers, the Waldahud equivalent of a double take.

"You make them?"  said Keith.

"Affirm.  Move stars--small tugs, takes long time.  Move stars into new
patterns, work to hold them there."

"You turned our galaxy into a spiral?"

"Who else?"

Who else indeed .  . .

"That's incredible," said Keith softly.

Jag was rising from his chair.  "No, that makes sense," the Waldahud
said.  "By all the gods, that makes sense.  I said there was no good
theory for explaining why galaxies acquired or maintained spiral shapes.

Being deliberately held in place by conscious dark matter--it's
mind-boggling, but it does make sense."

Keith keyed off the mike.  "But--but what about all the other galaxies?

You said three quarters of all galaxies are spirals."

Jag did a four-armed Waldahud shrug.  "Ask it."

"Did you make many galaxies into spirals?"

"Not us.  Others."

"I mean, did others of your kind make many galaxies into spirals?"

"Yes."

"But why?"

"Have to look at them.  Make pretty.  Make--make--a thing for
expressions not mathematic."

"Art," said Keith.

"Art, yes," said Cat's Eye.

Having left his chair, Jag now dropped down to all fours, the first time
Keith had ever seen him do that.  "Gods," he barked, his voice subdued.

"Gods."

"Well, it certainly fills that theoretical hole you were talking about,"
said Keith.  "It even explains that bit you mentioned about ancient
galaxies seeming to rotate faster than theory suggests they should. They
were being made to rotate, in order to spin out spiral arms."

"No, no, no," barked Jag.  "No, don't you understand?

Don't you see?  It's not just an esoteric point of galaxy formation
that's been explained.  We owe them everything--everything!"

The Waldahud took hold of one of the metal legs supporting Keith's
console and hauled himself back onto two feet again.  "I told you
earlier: Stable genetic molecules would have an almost impossible time
existing in a densely packed mass of stars, because of the radiation
levels.  It's only because our homeworlds exist far from the core, out
in the spiral arms, that life was able to arise on them at all.  We
exist--all the life made out of what we arrogantly refer to as 'regular
matter'--all of it exists simply because the dark-matter creatures were
playing with stars, swirling them into pretty patterns."

Thor had turned around to face Jag.  "But--but the biggest galaxies in
the universe are ellipticals, not spirals."

Jag lifted his upper shoulders.  "True.  But maybe shaping them is too
much work, or too time-consuming.  Even with faster-than-light
communications--with 'radio-two'-it would still take tens of thousands
of years for signals to pass from one side of a truly giant elliptical
to the other.  Maybe that's too much for a group effort.  But for
mid-sized galaxies like ours and Andromeda--well, every artist has a
preferred scale, no?  A favorite canvas size, or an affinity for either
short stories or novels.  Mid-sized galaxies are the medium .  . .

and .  . . and we are the message."

Thor was nodding.  "Jesus, he's right."  He looked at Keith.  "Remember
what Cat's Eye said when you asked it why it tried to kill us?  'Make
you.  Not make you."  My father used to say that, too, when he was
angry: 'I brought you into this world, boy, and I can take you out of
it."  They know--the darmats know that their activity is what has made
our kind of life possible."

Jag was losing his balance again.  He finally gave up, and dropped back
to his four hind legs, making him look like a chubby centaur.  ''Talk
about an ego blow," he said.

"This one is the biggest of them all.  Early on, each of the
Commonwealth races had thought its homeworld was the center of the
universe.  But, of course, they weren't.  Then we reasoned that dark
matter must exist--and, in a way, that was even more humbling.  It
meant.  that not only were we not the center of the universe, we're not
even made out of what most of the universe is made from!  We are like
the scum on a pond's surface daring to think that we are more important
than all the vast bulk of water that makes up the pond.

"And now this!"  His fur was dancing.  "Remember what Cat's Eye said
when you asked it how long ago dark-matter life had first arisen?

'Since the beginning of all the stars combined,' he said.  'Since the
beginning of the universe."" Keith nodded.

"He said they had to exist that far back--had to!"  Jag's fur was
rippling.  "I thought it was just a philosophical position, but he's
right, of course--life had to exist from the beginning of this universe,
or as near to the beginning as physically possible."

Keith stared at Jag.  "I don't understand."

"What arrogant fools we are!"  said Jag.  "Don't you see?

To this day, despite all the humbling lessons the universe has already
taught us, we still try to retain a central role in creation.  We devise
theories of cosmology that say the universe was destined to give rise to
us, that it had to evolve life like us.  Humans call it the anthropic
principle, my people called it the aj-Waldahudigralt principle, but it's
all the same thing: the desperate, deep-rooted need to believe that we
are significant, that we're important.

"We talk in quantum physics about Schredinger's cat or Teg's
kestoor--the idea that everything is just potentialities, just
wavefronts, unresolved, until one of us all-important qualified
observers lumbers by, has a peek, and, by the process of looking, causes
the wavefront to collapse.  We actually allowed ourselves to believe
that that is how the universe worked--even though we know full well that
the universe is many billions of years old, and not one of our races is
more than a million.

"Yes," barked Jag, "quantum physics demands qualified observers.  Yes,
intelligence is necessary to determine which possibility becomes
reality.  But in our arrogance we thought that the universe could work
for fifteen billion years without us, and yet that it somehow was geared
to give rise to us.

Such hubris!  The intelligent observers are not us--tiny beings,
isolated on a handful of worlds in all the vastness of space.  The
intelligent observers are the dark-matter creatures.

They have been spinning galaxies into spirals for billions upon billions
of years.  It is their intellect, their observations, their sentience
that drives the universe, that gives quantum potentialities concrete
reality.  We are nothing-nothing!--but a recent, localized phenomenon--a
spot of mold on a universe that doesn't need us, or care that we exist.

Cat's Eye was absolutely right when he said we were insignificant.

This is their universe--the darmats' universe.  They made it, and they
made us, too!"

Chapter XXV

Keith sat in his office on deck fourteen, looking over the latest news
from Tau Ceti.  Reports were sketchy, but on Rehbollo, forces loyal to
Queen Trath had put down the insurrection against her, and twenty-seven
conspirators had been summarily executed in the traditional method of
being drowned in boiling mud.

Keith set down the datapad.  The report strained credulity--it was the
first he'd heard of any political unrest on Rehbollo.

Still, maybe it was true--although more likely it was just a government
desperately trying to distance itself from a disastrous initiative.

A chime sounded, and PHANTOM's voice said, "Jag Kandaro em-Pelsh is
here."

Keith exhaled.  "Let him in."

Jag entered and found a polychair.  His left eyes were on Keith, but the
right pair were scanning the room in the instinctive fight-or-flight
pattern.  "I suppose at this juncture," he said, "I must fill out some
of those forms you humans are so fond of."

"What forms?"  said Keith.

"Forms for resigning my position aboard Starplex, of course.  I can no
longer serve here."

Keith rose to his feet, and permitted himself a stretch.

It had to begin somewhere--maturity, the stage after the midlife crisis,
peace.  It had to begin somewhere.

"Children play with toy soldiers," said Keith, looking now at Jag.

"Child races play with real ones.  Maybe it's time all of us grew up a
bit."

The Waldahud was quiet for a long moment.  "Maybe."

"We all have loyalties hardwired into our genes," said Keith.  "I won't
push for your resignation."

"Your comments assume that I am guilty of something.  I reject that.

But were it true, you still misunderstand.

Perhaps .  . . perhaps your people will always misunderstand mine."

Jag paused.  "And the converse, too, of course."

Another pause.  "No, it is time for me to return to Rehbollo."

"There's a lot of work left to be done here," said Keith.

"Doubtless so.  But the job I set for myself has been completed."

"Oh," said Keith, understanding dawning.  "You mean you've accrued
sufficient glory to win Pelsh."

"Exactly.  The discoveries I have been a part of involving the darmats
will make me the most celebrated scientist on Rehbollo."  A pause.

"Pelsh will make her decision soon.  I can tarry here no longer."

Keith thought for a moment.  "No female Waldahud has ever worked aboard
Starplex.  When my term of office ends, it will be an Ib's turn to be
director; I suspect Wineglass will get the job.  But after the Ib, the
position will then fall to a Waldahud--and I know the Waldahudin will
demand a female leader.  What if--what if you and Pelsh came to Starplex
together?  From what I've heard, she'd be a natural for the director's
job."

Jag's fur rippled in surprise.  "We can't do that.  We will both still
be part of a larger grouping.  She will retain her entourage until she
dies."

Keith's eyes widened a bit.  "You mean the males that don't succeed with
her don't get to try their luck elsewhere?"

"Of course not.  We will remain a family.  We have all been pledged to
Pelsh since childhood."

"Perhaps you could all come to serve aboard Starplex-all six of you."

Jag moved his lower shoulders.  "Starplex is for the best and brightest.

I would never speak to a Waldahud in disparaging terms about other
members of my lady's entourage, but I will tell you the truth.  It was
never a contest between me and four others.  Never.  It was between me
and one individual.  That was clear from the beginning.

The others .  . . lack distinction."

"But I thought Pelsh was related to the royal family.

Forgive me, but why would she have less than the most qualified
suitors?"

"An entourage must continue to function even after a mate is chosen.  A
skillfully selected entourage Will contain several members who will be
content with lesser stations.

Indeed, an entourage composed entirely of what you humans call alpha
males would be doomed."

Keith thought about this.  "Well, if the only way we can get you is to
take your whole family, then I will see to it that we do so."

"I--I do not think you will follow through on that."

Keith blinked.  "I'm a man of my word."

"The real contest for Pelsh was between me and one other.

That other, of course, has a name."  Jag's four eyes locked on Keith's
two.  "That name is Gawst Dalayo em-Pelsh."

"Gawst!"  said Keith.  "Who led the attack on Starplex?"

"Yes.  He escaped the darmats and is now back on Rehbollo."

Keith was still for ten seconds, then began to nod.  "You had to help
him, didn't you?"

"I have admitted nothing," said Jag.

"If you didn't help him, all the glory in bringing Starplex home to
Rehbollo would have been his; he would have been chosen by Pelsh.  By
assisting him, you assured that the glory would be shared."

"There are two hundred and sixty Waldahudin aboard Starplex," said Jag.

The sentence floated between them for several moments.

Keith nodded, understanding.  "So if you hadn't helped him, doubtless he
would have found someone else who would have," said Keith..

"Again," said Jag, "I admit nothing."  He was quiet for a time.  "Of
course, Queen Trath's government may bring criminal charges against
Gawst.  He soon may not have his liberty--or even his life."

"My offer still stands," said Keith.

Jag bowed his head.  "I--we--shall consider it."  And then Jag did
something Keith had never seen any Waldahud do before.  He added the
words, "Thank you."

It was evening; the corridor lighting was dimmed, As he always did just
prior to dinner, Keith dropped by the bridge, and had a word with the
gamma-shift director, a Waldahud named Stelt.  Everything was running
smoothly, Stelt said.

Not a surprise; Keith would have been called at once had something been
amiss.  Keith wished everyone a pleasant night and left the bridge,
heading toward the central shaft.

Lianne Karendaughter was there, sitting on a bench in the widened part
of the corridor just before the elevators.  She looked lithe and sexy in
a skintight black jumpsuit.

Surely a coincidence, thought Keith.  Surely she didn't know his
murine--know that he passed this way every evening at this time.  She
must be waifng for somebody else.

Lianne had her hair down; Keith had never realized that it went halfway
down her back.  "Hello, Keith," she said, smiling warmly.

"Hello, Lianne.  Did--did you have a good day?"

"Oh, yes.  I mean, you saw alpha shift today--a breeze.

And I got to do some swimming and fencing during beta shift.  How about
you?"

"Fine.  Just fine."

"That's good," said Lianne.  She paused for a moment, and looked down
at the rubberized flooring.  When she lifted her head again, she didn't
quite meet Keith's eyes.  "I, ah, understand Rissa is away today."

"That's right.  She's taken a pod back to Grand Central.  I think she's
trying to find a way not to have to accept a medal, or have a parade in
her honor."

Lianne nodded.  "So I was thinking," she said, after a moment, "that
perhaps you'd be all alone for dinner."

Keith felt his pulse quickening.  "I--I suppose I am," he said.

Lianne smiled at him.  She had perfect white teeth, perfect alabaster
skin, and the most beautiful dark, haunting, almond-shaped eyes.  "I
wondered if you'd like to join me.  I've got a wok in my apartment; I
could make that stir-fry I promised you."

Keith looked at .  . . at the girl, he thought.  Twenty-seven.

Two decades younger than himself.  He felt a slight shifting in his
shorts.  It was probably just an innocent invitation.  She felt sorry
for the old guy, or maybe was trying to ingratiate herself with the
boss.  Just some stir-fry, mayhe some wine, maybe .  . .

"You know, Lianne," said Keith, "you are a very beautiful woman.  He held
up a hand.  "I know, I'm not supposed to say things like that, but we're
both off duty.  You're a very beautiful woman."  She lowered her eyes:
He paused and chewed on his bottom lip.  And a thought welled up in his
brain.

Don't hurt Rissa.

You'll only hurt yourself.

"But," he said at last, "I think it's better if I just admire you from
afar."

She met his eyes for a moment, then dropped hers again.

"Rissa is a very lucky woman," Lianne said.

"No," said Keith, "I'm a very lucky man.  See you tomorrow, Lianne."

She nodded.  "Good night, Keith."

He went home, made himself a sandwich, read a few chapters in an old
Robertson Davies novel, then went to bed early.

And slept like a log, absolutely at peace with himself.

Alpha shift the next day started uneventfully.  Rhombus had arrived
precisely on time, of course; Thor came in, put his feet up on the helm
console, and started dictating instructions into the navigational
computer; Lianne was hard at work briefing little holographic heads of
her engineers on the day's proposed work.  In the back row, Keith was
talking quietly to Rissa, who had just returned from Grand Central.

But then the starscape split, and Jag came in, moving with more of a run
than a waddle.

"I've got it!"  he said--although from the excited waving of his fur,
perhaps "Eureka!"  would have been a more appropriate translation.

Keith and Rissa turned to look at Jag.  He didn't go to his workstation;
instead, he moved to the front of the room, standing about two meters
ahead of Thor's console.

"What have you got?"  asked Keith, resisting the potential straight
line.

"The answer!"  barked Jag excitedly.  "The answer!"  He caught his
breath.  "Bear with me for a moment; this will take some explaining.

But I'll tell you one thing up front--we do matter!  We do make a
difference.  Gods of the mountains, rivers, valleys, and plains--we make
all the difference!"  His eyes diverged, one falling on Lianne, a second
on Rhombus, a third on Rissa, and the fourth on Thor and Keith, who were
lined up one behind the other from Jag's point of view.

"We know now that time travel from the future into the past is
possible," he said.  "We've seen it happen with the fourth-generation
stars, and with the time capsule Hek and Azmi built.  But consider the
implications of that.  Suppose that at noon tomorrow, I used a time
machine to send myself back in time to today.  What would we have then?"

Keith said, "Well, there'd be two of you, right?  The Jag from today,
and the Jag from tomorrow."

"That's right.  Now think about that: if you have two of me, you've
doubled the mass.  I mass one hundred and twenty-three kilograms, but if
there were two of me here, then there'd be two hundred and forty-six
kilos of ]ag-mass aboard this ship."

"But I thought that was impossible," said Rissa, "because of the law of
conservation of mass and energy.  Where did the extra hundred and
twenty-three kilos come from?"

Jag looked triumphant.  "From the future!  Don't you see?  Time travel
is the only conceivable way to overcome that law.  It's the only way to
increase the total mass in the system."  His fur continued to dance.

"And what about the stars from the future?  As each arrives, the mass of
the present-day universe is increased.  After all, even
fourth-generation stars are made up of preexisting recycled subatomic
particles.  Pushing them back in time means that those particles have
essentially been duplicated, doubling their total mass."

"An interesting side effect no doubt," said Rhombus.  "But it still
doesn't explain why the stars are being sent back."

"Oh, yes it does.  The doubling of mass is not just a side effect--not
at all!  Rather, it's the whole point of.  the operation."

"Operation?"  said Keith.

"Yes!  The operation to save the universe!  These stars are being pushed
back in time to increase the mass of the entire universe."

Keith felt his jaw dropping.  "Good God."

All four of the Waldahud's eyes converged on Keith.

"Exactly!"  barked Jag.  "We've known for over a century that the
visible matter in the universe accounts for less than ten percent of the
total that must be present.  The rest is neutrinos and dark matter, like
our giant friends outside the ship.  We now know what all the matter in
the universe is, but we don't know how much there is in total.  And the
fate of the universe depends on how much mass it has, on whether the
total is above, below, or precisely at the so-called critical density."

"Critical density?"  asked Rissa.

"That's right.  The universe is expanding--and has been ever since the
big bang.  But will that expansion go on forever?

That depends on gravity.  And how much gravity there is, of course,
depends on how much mass there is.  If there isn't enough--if the mass
of the universe is less than the critical density--gravity will never
overpower the original explosion, and the universe will continue to
expand forever, all the matter in it spreading out farther and farther.

Everything will grow cold and empty, with light-years separating
individual atoms."

Rissa shuddered.

"I suppose," said Keith.  -"But what a project!"

"Indeed," said Jag.  "And it might be even greater in scope than it
first seems.  Tell me: How old is this universe right now?"

"Fifteen billion years," Keith said.  "Earth years, that is."

Jag moved his lower shoulders.  "Actually, although that is the most
commonly cited figure, no astrophysicist believes it.

Fifteen is a compromise, halfway between the ages of the universe
suggested by two different lines of reasoning.  The universe is either
as young as ten billion years, or as old as twenty.  Since the
mid-1990s, the accepted value of the Hubble constant--which measures the
rate of expansion of the universe--has been about eighty-five kilometers
per second per megaparsec.  That means the universe is still flinging
apart at a great rate from the original big bang--that gravity has done
little to slow the expansion so far--and therefore it can't be much more
than about ten billion years old.

"But spectral studies of extreme first,generation stars, especially
those in globular clusters, suggest that such stars have been undergoing
fusion for almost twice that length of time.

We've long assumed that one calculation or the other must be wrong.

But perhaps neither is.  Perhaps what we're seeing now is merely the
most recent phase of a multistage project.

Perhaps I was premature in rejecting Magnor's suggestion earlier about
pushing globular clusters through shortcuts.

Perhaps such clusters, each containing tens of thousands of stars, have
already been shoved back from the future.  It's possible that originally
this universe contained far, far less than ninety-five percent of the
critical density of matter, and that the current phase of the project is
just some fine-tuning."

"But--but surely the mass doubling is only temporary," said Lianne, "To
go back to your original example, if you traveled back from tomorrow to
today, there'd be two of you today--but tomorrow, one of them would
presumably disappear back into the past."

"Perhaps so," said Jag.  "But for the entire span between the departure
point in the future and the arrival point in the present, you have
doubled the mass.  And if those two points were separated by ten billion
years, then you've doubled the mass for a very long time indeed--long
enough for its effects to put the brakes on the universe's expansion. If
you calculate with great care, you don't need to permanently increase
the mass of the universe.  You only need to do it long enough for
gravitational attraction to halt the rate of expansion of the original
explosion.  If you do it just right, even without a permanent increase
in mass, you could end up with a universe in the far future that is
indeed precisely balanced--a universe that will live forever."

Jag paused for breath.  "It's the most massive engineering project ever
undertaken," he said.  "But it sure beats the alternative--which was to
let the universe die."  He beamed at the members of the bridge staff.

"We did it.  Regular-matter creatures--creatures with hands!  In the
end--correction, to prevent the end--the universe needed us!"

The ceremony, held in their favorite Waldahud restaurant, was short.

The audience was much bigger than their original family-only wedding in
Madrid; any sort of celebration was welcomed aboard Starplex.

Thoraid Magnor had been promoted to acting director for the day so that
he could perform the service.  "Do you, Gilbert Keith," he said, "again
take Clarissa Maria, to love, honor, and cherish, in sickness and in
health, for richer or poorer?"

Keith turned to face his wife.  He remembered the day twenty years ago,
the day they had first gone through this ritual, a wonderful, happy day.

It had been a good marriage--stimulating intellectually, emotionally,
and physically.  And she was, if anything, more beautiful, more
challenging today than then.  He looked into her large brown eyes, and
said, "I do."

Thor turned to face her, but before he could speak, Keith squeezed his
wife's hand and added, loudly, for all to hear, "For as long as we both
shall live."

Rissa smiled at him radiantly.

Hell, thought Keith, twenty years was just scratching the surface .

**EPILOGUE**

Keith Lansing had been sleeping well for weeks now.  He lay in bed, next
to his beautiful wife, drifting off to sleep.  So what if he and Rissa
and Jag and Longbottle and Rhombus and all the other billions of
Commonwealth citizens didn't yet amount to a hill of beans in this crazy
universe?  So what if they were a cosmic afterthought, an unexpected
by-product of dark-matter art?  Someday they would make a
difference--they would make all the difference .  . .

Keith woke with a start.  He pulled back the little card covering his
clock face; it was 0143.  He sat up in bed and listened to the white
noise PHANTOM was playing through the room's sound system.

Christ, he thought.  Good Christ.

Pushing billions of stars from the future back in time would change the
past--change it radically, change it chaotically.  There's no way the
time line would unfold the same way as it had originally--no way this
past would end up giving rise to the same future.  You couldn't avoid a
paradox--unless .  . . unless .  . .

Unless you were going to come back in time yourself--back to a time
before the first matter from the future appeared.  Keith felt his heart
racing.  All the beings from the far future must be here already,
somewhere in the present.

He recalled the pictures he'd seen of that smooth ball of metal--metal
that had once been the boomerang sent from Tau Ceti to the Tejat
Posterior shortcut, metal altered by fantastically advanced science.

The Slammers had indeed closed the door on the Commonwealth .  . .

closed the door on their own past.  They'd made it very clear that they
wanted to--needed to--remain isolated from the earlier versions of
themselves.

Using that shortcut--and doubtless countless others--were people from
the future.  And among those people would be the version of himself that
had signed the message on the time capsule, the version who was
apparently a leader of the project to save the universe--a
multibillion-year-old Keith Lansing, a Keith Lansing who had become,
quite literally, the grand old man of physics.  How he would love to
meet that other self .  . .

Keith looked at Rissa in the dim light.  She was still fast asleep, but
his movements in the bed had pulled the sheet off her.  He gingerly
replaced it, then lay back against the pillow, and slowly fell into
unconsciousness, dreaming of a glass man.
