J. G. Ballard - Zone of Terror

Larsen had been waiting all day for Bayliss, the psychologist who lived in the next chalet, to pay the call he had promised on the previous evening. Characteristically, Bayliss had made no precise arrangements as regards time; a tall, moody man with an off-hand manner, he had merely gestured vaguely with his hypodermic and mumbled something about the following day: he would look in, probably. Larsen knew damned well he would look in, the case was too interesting to miss. In an oblique way it meant as much to Bayliss as it did to himself.

Except that it was Larsen who had to do the worrying - by three that afternoon Bayliss had still not materialized. What was he doing except sitting in his white-walled, air-conditioned lounge, playing Bartok quartets on the stereogram? Meanwhile Larsen had nothing to do but roam around the chalet, slamming impatiently from one room to the next like a tiger with an anxiety neurosis, and cook up a quick lunch (coffee and three amphetamines, from a private cache Bayliss as yet only dimly suspected. God, he needed the stimulants after those massive barbiturate shots Bayliss had pumped into him after the attack). He tried to settle down with Kretschmer's _An Analysis of Psychotic Time_, a heavy tome, full of graphs and tabular material, which Bayliss had insisted he read, asserting that it filled in necessary background to the case. Larsen had spent a couple of hours on it, but so far he had got no further than the preface to the third edition.

Periodically he went over to the window and peered through the plastic blind for any signs of movement in the next chalet. Beyond, the desert lay in the sunlight like an enormous bone, against which the aztec-red fins of Bayliss's Pontiac flared like the tail feathers of a flamboyant phoenix. The remaining three chalets were empty; the complex was operated by the electronics company for which he and Bayliss worked as a sort of 're-creational' centre for senior executives and tired 'think-men'. The desert site had been chosen for its hypotensive virtues, its supposed equivalence to psychic zero. Two or three days of leisurely reading, of watching the motionless horizon, and tension and anxiety thresholds rose to more useful levels.

However, two days there, Larsen reflected, and he had very nearly gone mad. It was lucky Bayliss had been around with his hypodermic. Though the man was certainly casual when it came to supervising his patients; he left them to their own resources. In fact, looking back, he - Larsen - had been responsible for just about all the diagnosis. Bayliss had done little more than thumb his hypo, toss Kretschmer into his lap, and offer some cogitating asides.

Perhaps he was waiting for something?

Larsen tried to decide whether to phone Bayliss on some pretext; his number - 0, on the internal system - was almost too inviting. Then he heard a door clatter outside, and saw the tall, angular figure of the psychologist crossing the concrete apron between the chalets, head bowed pensively in the sharp sunlight.

Where's his case, Larsen thought, almost disappointed. Don't tell me he's putting on the barbiturate brakes. Maybe he'll try hypnosis. Masses of post-hypnotic suggestions, in the middle of shaving I'll suddenly stand on my head.

He let Bayliss in, fidgeting around him as they went into the lounge.

'Where the hell have you been?' he asked. 'Do you realize it's nearly four?'

Bayliss sat down at the miniature executive desk in the middle of the lounge and looked round critically, a ploy Larsen resented but never managed to anticipate.

'Of course I realize it. I'm fully wired for time. How have you felt today?' He pointed to the straight-backed chair placed in the interviewee's position. 'Sit down and try to relax.'

Larsen gestured irritably. 'How can I relax while I'm just hanging around here, waiting for the next bomb to go off?' He began his analysis of the past twenty-four hours, a task he enjoyed, larding the case history with liberal doses of speculative commentary.

'Actually, last night was easier. I think I'm entering a new zone. Everything's beginning to stabilize, I'm not looking over my shoulder all the time. I've left the inside doors open, and before I enter a room I deliberately anticipate it, try to extrapolate its depth and dimensions so that it doesn't surprise me - before I used to open a door and just dive through like a man stepping into an empty lift shaft.'

Larsen paced up and down, cracking his knuckles. Eyes half closed, Bayliss watched him. 'I'm pretty sure there won't be another attack,' Larsen continued. 'In fact, the best thing is probably for me to get straight back to the plant. After all, there's no point in sitting around here indefinitely. I feel more or less completely okay.'

Bayliss nodded. 'In that case, then, why are you so jumpy?'

Exasperated, Larsen clenched his fists. He could almost hear the artery thudding in his temple. 'I'm not jumpy! For God's sake, Bayliss, I thought the advanced view was that psychiatrist and patient shared the illness together, forgot their own identities and took equal responsibility. You're trying to evade - '

'I am not,' Bayliss cut in firmly. 'I accept complete responsibility for you. That's why I want you to stay here until you've come to terms with this thing.'

Larsen snorted. "Thing"! Now you're trying to make it sound like something out of a horror film. All I had was a simple hallucination. And I'm not even completely convinced it was that.' He pointed through the window. 'Suddenly opening the garage door in that bright sunlight it might have been a shadow.'

'You described it pretty exactly,' Bayliss commented. 'Colour of the hair, moustache, the clothes he wore.'

'Back projection. The detail in dreams is authentic too.' Larsen moved the chair out of the way and leaned forwards across the desk. 'Another thing. I don't feel you're being entirely frank.'

Their eyes levelled. Bayliss studied Larsen carefully for a moment, noticing his widely dilated pupils.

'Well?' Larsen pressed.

Bayliss buttoned his jacket and walked across to the door. 'I'll call in tomorrow. Meanwhile try to unwind yourself a little. I'm not trying to alarm you, Larsen, but this problem may be rather more complicated than you imagine.' He nodded, then slipped out before Larsen could reply.

Larsen stepped over to the window and through the blind watched the psychologist disappear into his chalet. Disturbed for a moment, the sunlight again settled itself heavily over everything. A few minutes later the sounds of one of the Bartok quartets whined fretfully across the apron.

Larsen went back to the desk and sat down, elbows thrust forward aggressively. Bayliss irritated him, with his neurotic music and inaccurate diagnoses. He felt tempted to climb straight into his car and drive back to the plant. Strictly speaking, though, the psychologist outranked Larsen, and probably had executive authority over him while he was at the chalet, particularly as the five days he had spent there were on the company's time.

He gazed round the silent lounge, tracing the cool horizontal shadows that dappled the walls, listening to the low soothing hum of the airconditioner. His argument with Bayliss had refreshed him and he felt composed and confident. Yet residues of tension and uneasiness still existed, and he found it difficult to keep his eyes off the open doors to the bedroom and kitchen.

He had arrived at the chalet five days earlier, exhausted and overwrought, on the verge of a total nervous collapse. For three months he had been working without a break on programming the complex circuitry of a huge brain simulator which the company's Advanced Designs Division were building for one of the major psychiatric foundations. This was a complete electronic replica of the central nervous system, each spinal level represented by a single computer, other computers holding memory banks in which sleep, tension, aggression and other psychic functions were coded and stored, building blocks that could be played into the CNS simulator to construct models of dissociation states and withdrawal syndromes - any psychic complex on demand.

The design teams working on the simulator had been watched vigilantly by Bayliss and his assistants, and the weekly tests had revealed the mounting load of fatigue that Larsen was carrying. Finally Bayliss had pulled him off the project and sent him out to the desert for two or three days' recuperation.

Larsen had been glad to get away. For the first two days he had lounged aimlessly around the deserted chalets, pleasantly fuddled by the barbiturates Bayliss prescribed, gazing out across the white deck of the desert floor, going to bed by eight and sleeping until noon. Every morning the caretaker had driven in from the town near by to clean up and leave the groceries and menu slips, but Larsen never saw her. He was only too glad to be alone. Deliberately seeing no one, allowing the natural rhythms of his mind to reestablish themselves, he knew he would soon recover.

In fact, however, the first person he had seen had stepped up to him straight out of a nightmare.

Larsen still looked back on the encounter with a shudder.

After lunch on his third day at the chalet he had decided to drive out into the desert and examine an old quartz mine in one of the canyons. This was a two-hour trip and he had made up a thermos of iced martini. The garage was adjacent to the chalet, set back from the kitchen side entrance, and fitted with a roll steel door that lifted vertically and curved up under the roof.

Larsen had locked the chalet behind him, then raised the garage door and driven his car out on to the apron. Going back for the thermos which he had left on the bench at the rear of the garage, he had noticed a full can of petrol in the shadows against one corner. For a moment he paused, adding up his mileage, and decided to take the can with him. He carried it over to the car, then turned round to close the garage door.

The roll had failed to retreat completely when he had first raised it, and reached down to the level of his chin. Putting his weight on the handle, Larsen managed to move it down a few inches, but the inertia was too much for him. The sunlight reflected in the steel panels was dazzling his eyes. Pressing his palms under the door, he jerked it upwards slightly to gain more momentum on the downward swing.

The space was small, no more than six inches, but it was just enough for him to see into the darkened garage.

Hiding in the shadows against the back wall near the bench was the indistinct but nonetheless unmistakable figure of a man. He stood motionless, arms loosely at his sides, watching Larsen. He wore a light cream suit - covered by patches of shadow that gave him a curious fragmentary look - a neat blue sports-shirt and two-tone shoes. He was stockily built, with a thick brush moustache, a plump face, and eyes that stared steadily at Larsen but somehow seemed to be focused beyond him.

Still holding the door with both hands, Larsen gaped at the man. Not only was there no means by which he could have entered the garage - there were no windows or side doors - but there was something aggressive about his stance.

Larsen was about to call to him when the man moved forward and stepped straight out of the shadows towards him.

Aghast, Larsen backed away. The dark patches across the man's suit were not shadows at all, but the outline of the work bench directly behind him.

The man's body and clothes were transparent.

Galvanized into life, Larsen seized the garage door and hurled it down. He snapped the bolt in and jammed it closed with both hands, knees pressed against it.

Half paralysed by cramp and barely breathing, his suit soaked with sweat, he was still holding the door down when Bayliss drove up thirty minutes later.

Larsen drummed his fingers irritably on the desk, stood up and went into the kitchen. Cut off from the barbiturates they had been intended to counteract, the three amphetamines had begun to make him feel restless and overstimulated. He switched the coffee percolator on and then off, prowled back to the lounge and sat down on the sofa with the copy of Kretschmer.

He read a few pages, increasingly impatient. What light Kretschmer threw on his problem was hard to see; most of the case histories described deep schizos and irreversible paranoids. His own problem was much more superficial, a momentary aberration due to overloading. Why wouldn't Bayliss see this? For some reason he seemed to be unconsciously wishing for a major crisis, probably because he, the psychologist, secretly wanted to become the patient.

Larsen tossed the book aside and looked out through the window at the desert. Suddenly the chalet seemed dark and cramped, a claustrophobic focus of suppressed aggressions. He stood up, strode over to the door and stepped out into the clear open air.

Grouped in a loose semicircle, the chalets seemed to shrink towards the ground as he strolled to the rim of the concrete apron a hundred yards away. The mountains behind loomed up enormously. It was late afternoon, on the edge of dusk, and the sky was a vivid vibrant blue, the deepening colours of the desert floor overlaid by the huge lanes of shadow that reached from the mountains against the sunline. Larsen looked back at the chalets. There was no sign of movement, other than a faint discordant echo of the atonal music Bayliss was playing. The whole scene seemed suddenly unreal.

Reflecting on this, Larsen felt something shift inside his mind. The sensation was undefined, like an expected cue that had failed to materialize, a forgotten intention. He tried to recall it, unable to remember whether he had switched on the coffee percolator.

He walked back to the chalets, noticing that he had left the kitchen door open. As he passed the lounge window on his way to close it he glanced in.

A man was sitting on the sofa, legs crossed, face hidden by the volume of Kretschmer. For a moment Larsen assumed that Bayliss had called in to see him, and walked on, deciding to make coffee for them both. Then he noticed that the stereogram was still playing in Bayliss's chalet.

Picking his steps carefully, he moved back to the lounge window. The man's face was still hidden, but a single glance confirmed that the visitor was not Bayliss. He was wearing the same cream suit Larsen had seen two days earlier, the same two-tone shoes. But this time the man was no hallucination; his hands and clothes were solid and palpable. He shifted about on the sofa, denting one of the cushions, and turned a page of the book, flexing the spine between his hands.

Pulse thickening, Larsen braced himself against the window-ledge. Something about the man, his posture, the way he held his hands, convinced him that he had seen him before their fragmentary encounter in the garage.

Then the man lowered the book and threw it on to the seat beside him. He sat back and looked through the window, his focus only a few inches from Larsen's face.

Mesmerized, Larsen stared back at him. He recognized the man without doubt, the pudgy face, the nervous eyes, the too thick moustache. Now at last he could see him clearly and realized he knew him only too well, better than anyone else on Earth.

The man was himself.

Bayliss clipped the hypodermic into his valise, and placed it on the lid of the stereogram.

'Hallucination is the wrong term altogether,' he told Larsen, who was lying stretched out on Bayliss's sofa, sipping weakly at a glass of hot whisky. 'Stop using it. A psychoretinal image of remarkable strength and duration, but not an hallucination.'

Larsen gestured feebly. He had stumbled into Bayliss's chalet an hour earlier, literally beside himself with fright. Bayliss had calmed him down, then dragged him back across the apron to the lounge window and made him accept that his double was gone. Bayliss was not in the least surprised at the identity of the phantom, and this worried Larsen almost as much as the actual hallucination. What else was Bayliss hiding up his sleeve?

'I'm surprised you didn't realize it sooner yourself,' Bayliss remarked. 'Your description of the man in the garage was so obvious - the same cream suit, the same shoes and shirt, let alone the exact physical similarity, even down to your moustache.'

Recovering a little, Larsen sat up. He smoothed down his cream gabardine suit and brushed the dust off his brown-and-white shoes. 'Thanks for warning me. All you've got to do now is tell me who he is.'

Bayliss sat down in one of the chairs. 'What do you mean, who he is? He's you, of course.'

'I know that, but why, where does he come from? God, I must be going insane.'

Bayliss snapped his fingers. 'No you're not. Pull yourself together. This is a purely functional disorder, like double vision or amnesia; nothing more serious. If it was, I'd have pulled you out of here long ago. Perhaps I should have done that anyway, but I think we can find a safe way out of the maze you're in.'

He took a notebook out of his breast pocket. 'Let's have a look at what we've got. Now, two features stand out. First, the phantom is yourself. There's no doubt about that; he's an exact replica of you. More important, though, he is you as you are now, your exact contemporary in time, unidealized and unmutilated. He isn't the shining hero of the super-ego, or the haggard grey-beard of the death wish. He is simply a photographic double. Displace one eyeball with your finger and you'll see a double of me. Your double is no more unusual, with the exception that the displacement is not in space but in time. You see, the second thing I noticed about your garbled description of this phantom was that, not only was he a photographic double, but he was doing exactly what you yourself had been doing a few minutes previously. The man in the garage was standing by the workbench, just where you stood when you were wondering whether to take the can of petrol. Again, the man reading in the armchair was merely repeating exactly what you had been doing with the same book five minutes earlier. He even stared out of the window as you say you did before going out for a stroll.'

Larsen nodded, sipping his whisky. 'You're suggesting that the hallucination was a mental flashback?'

'Precisely. The stream of retinal images reaching the optic lobe is nothing more than a film strip. Every image is stored away, thousands of reels, a hundred thousand hours of running time. Usually flashbacks are deliberate, when we consciously select a few blurry stills from the film library, a childhood scene, the image of our neighbourhood streets we carry around with us all day near the surface of consciousness. But upset the projector slightly - overstrain could do it - jolt it back a few hundred frames, and you'll superimpose a completely irrelevant strip of already exposed film, in your case a glimpse of yourself sitting on the sofa. It's the apparent irrelevancy that is so frightening.'

Larsen gestured with his glass. 'Wait a minute, though. When I was sitting on the sofa reading Kretschmer I didn't actually see myself, any more than I can see myself now. So where did the superimposed images come from?'

Bayliss put away his notebook. 'Don't take the analogy of the film strip too literally. You may not see yourself sitting on that sofa, but your awareness of being there is just as powerful as any visual corroboration. It's the stream of tactile, positional and psychic images that form the real data store. Very little extrapolation is needed to transpose the observer's eye a few yards to the other side of a room. Purely visual memories are never completely accurate anyway.'

'How do you explain why the man I saw in the garage was transparent?'

'Quite simply. The process was only just beginning, the intensity of the image was weak. The one you saw this afternoon was much stronger. I cut you off barbiturates deliberately, knowing full well that those stimulants you were taking on the sly would set off something if they were allowed to operate unopposed.'

He went over to Larsen, took his glass and refilled it from the decanter. 'But let's think of the future. The most interesting aspect of all this is the light it throws on one of the oldest archetypes of the human psyche - the ghost - and the whole supernatural army of phantoms, witches, demons and so on. Are they all, in fact, nothing more than psychoretinal flashbacks, transposed images of the observer himself, jolted on to the retinal screen by fear, bereavement, religious obsession? The most notable thing about the majority of ghosts is how prosaically equipped they are, compared with the elaborate literary productions of the great mystics and dreamers. The nebulous white sheet is probably the observer's own nightgown. It's an interesting field for speculation. For example, take the most famous ghost in literature and reflect how much more sense Hamlet makes if you realize that the ghost of his murdered father is really Hamlet himself.'

'All right, all right,' Larsen cut in irritably. 'But how does this help me?'

Bayliss broke off his reflective up-and-down patrol of the floor and fixed an eye on Larsen. 'I'm coming to that. There are two methods of dealing with this disfunction of yours. The classical technique is to pump you full of tranquillizers and confine you to a bed for a year or so. Gradually your mind would knit together. Long job, boring for you and everybody else. The alternative method is, frankly, experimental, but I think it might work. I mentioned the phenomenon of the ghost because it's an interesting fact that although there have been tens of thousands of recorded cases of people being pursued by ghosts, and a few of the ghosts themselves being pursued, there have been no cases of ghost and observer actually meeting of their own volition. Tell me, what would have happened if, when you saw your double this afternoon, you had gone straight into the lounge and spoken to him?'

Larsen shuddered. 'Obviously nothing, if your theory holds. I wouldn't like to test it.'

'That's just what you're going to do. Don't panic. The next time you see a double sitting in a chair reading Kretschmer, go up and speak to him. If he doesn't reply sit down in the chair yourself. That's all you have to do.'

Larsen jumped up, gesticulating. 'For heaven's sake, Bayliss, are you crazy? Do you know what it's like to suddenly see yourself? All you want to do is run.'

'I realize that, but it's the worst thing you can do. Why whenever anyone grapples with a ghost does it always vanish instantly? Because forcibly occupying the same physical co-ordinates as the double jolts the psychic projector on to a single channel again. The two separate streams of retinal images coincide and fuse. You've got to try, Larsen. It may be quite an effort, but you'll cure yourself once and for all.'

Larsen shook his head stubbornly. 'The idea's insane.' To himself he added: I'd rather shoot the thing. Then he remembered the .38 in his suitcase, and the presence of the weapon gave him a stronger sense of security than all Bayliss's drugs and advice. The revolver was a simple symbol of aggression, and even if the phantom was only an intruder in his own mind, it gave that portion which still remained intact greater confidence, enough possibly to dissipate the double's power.

Eyes half closed with fatigue, he listened to Bayliss. Half an hour later he went back to his chalet, found the revolver and hid it under a magazine in the letterbox outside the front door. It was too conspicuous to carry and anyway might fire accidentally and injure him. Outside the front door it would be safely hidden and yet easily accessible, ready to mete out a little old-fashioned punishment to any double dealer trying to get into the game.

Two days later, with unexpected vengeance, the opportunity came.

Bayliss had driven into town to buy a new stylus for the stereogram, leaving Larsen to prepare lunch for them while he was away. Larsen pretended to resent the chore, but secretly he was glad of something to do. He was tired of hanging around the chalets while Bayliss watched him as if he were an experimental animal, eagerly waiting for the next crisis. With luck this might never come, if only to spite Bayliss, who had been having everything too much his own way.

After laying the table in Bayliss's kitchenette and getting plenty of ice ready for the martinis (alcohol was just the thing, Larsen readily decided, a wonderful CNS depressant) he went back to his chalet and put on a clean shirt. On an impulse he decided to change his shoes and suit as well, and fished out the blue office serge and black oxfords he had worn on his way out to the desert. Not only were the associations of the cream suit and sports shoes unpleasant, but a complete change of costume might well forestall the double's reappearance, provide a fresh psychic image of himself powerful enough to suppress any wandering versions. Looking at himself in the mirror, he decided to carry the principle even farther. He switched on his shaver and cut away his moustache. Then he thinned out his hair and plastered it back smoothly across his scalp.

The transformation was effective. When Bayliss climbed out of his car and walked into the lounge he almost failed to recognize Larsen. He flinched back at the sight of the sleek-haired, dark-suited figure who stepped from behind the kitchen door.

'What the hell are you playing at?' he snapped at Larsen. 'This is no time for practical jokes.' He surveyed Larsen critically. 'You look like a cheap detective.'

Larsen guffawed. The incident put him in high spirits, and after several martinis he began to feel extremely buoyant. He talked away rapidly through the meal. Strangely, though, Bayliss seemed eager to get rid of him; he realized why shortly after he returned to his chalet. His pulse had quickened. He found himself prowling around nervously; his brain felt overactive and accelerated. The martinis had only been partly responsible for his elation. Now that they were wearing off he began to see the real agent - a stimulant Bayliss had given him in the hope of precipitating another crisis.

Larsen stood by the window, staring out angrily at Bayliss's chalet. The psychologist's utter lack of scruple outraged him. His fingers fretted nervously across the blind. Suddenly he felt like kicking the whole place down and speeding off. With its plywood-thin walls and match-box furniture the chalet was nothing more than a cardboard asylum. Everything that had happened there, the breakdowns and his nightmarish phantoms, had probably been schemed up by Bayliss deliberately.

Larsen noticed that the stimulant seemed to be extremely powerful. The take-off was sustained and unbroken. He tried hopelessly to relax, went into the bedroom and kicked his suitcase around, lit two cigarettes without realizing it.

Finally, unable to contain himself any longer, he slammed the front door back and stormed out across the apron, determined to have everything out with Bayliss and demand an immediate sedative.

Bayliss's lounge was empty. Larsen plunged through into the kitchen and bedroom, discovered to his annoyance that Bayliss was having a shower. He hung around in the lounge for a few moments, then decided to wait in his chalet.

Head down, he crossed the bright sunlight at a fast stride, and was only a few steps from the darkened doorway when he noticed that a man in a blue suit was standing there watching him.

Heart leaping, Larsen shrank back, recognizing the double even before he had completely accepted the change of costume, the smooth-shaven face with its altered planes. The man hovered indecisively, flexing his fingers, and appeared to be on the verge of stepping down into the sunlight.

Larsen was about ten feet from him, directly in line with Bayliss's door. He backed away, at the same time swinging to his left to the lee of the garage. There he stopped and pulled himself together. The double was still hesitating in the doorway, longer, he was sure, than he himself had done. Larsen looked at the face, repulsed, not so much by the absolute accuracy of the image, but by a strange, almost luminous pastiness that gave the double's features the waxy sheen of a corpse. It was this unpleasant gloss that held Larsen back - the double was an arm's length from the letterbox holding the .38, and nothing could have induced Larsen to approach it.

He decided to enter the chalet and watch the double from behind. Rather than use the kitchen door, which gave access to the lounge on the double's immediate right, he turned to circle the garage and climb in through the bedroom window on the far side.

He was picking his way through a dump of old mortar and barbed wire behind the garage when he heard a voice call out: 'Larsen, you idiot, what do you think you're doing?'

It was Bayliss, leaning out of his bathroom window. Larsen stumbled, found his balance and waved Bayliss back angrily. Bayliss merely shook his head and leaned farther out, drying his neck with a towel.

Larsen retraced his steps, signalling to Bayliss to keep quiet. He was crossing the space between the garage wall and the near corner of Bayliss's chalet when out of the side of his eye he noticed a dark-suited figure standing with its back to him a few yards from the garage door.

The double had moved! Larsen stopped, Bayliss forgotten, and watched the double warily. He was poised on the balls of his feet, as Larsen had been only a minute or so earlier, elbows up, hands waving defensively. His eyes were hidden, but he appeared to be looking at the front door of Larsen's chalet.

Automatically, Larsen's eyes also moved to the doorway.

The original blue-suited figure still stood there, staring out into the sunlight.

There was not one double now, but two.

For a moment Larsen stared helplessly at the two figures, standing on either side of the apron like half-animated dummies in a waxworks tableau.

The figure with its back to him swung on one heel and began to stalk rapidly towards him. He gazed sightlessly at Larsen, the sunlight exposing his face. With a jolt of horror Larsen recognized for the first time the perfect similarity of the double - the same plump cheeks, the same mole by the right nostril, the white upper lip with the same small razor cut where the moustache had been shaved away. Above all he recognized the man's state of shock, the nervous lips, the tension around the neck and facial muscles, the utter exhaustion just below the surface of the mask.

His voice strangled, Larsen turned and bolted.

He stopped running about two hundred yards out in the desert beyond the edge of the apron. Gasping for breath, he dropped to one knee behind a narrow sandstone outcropping and looked back at the chalets. The second double was making his way around the garage, climbing through the tangle of old wire. The other was crossing the space between the chalets. Oblivious of them both, Bayliss was struggling with the bathroom window, forcing it back so that he could see out into the desert.

Trying to steady himself, Larsen wiped his face on his jacket sleeve. So Bayliss had been right, although he had never anticipated that more than one image could be seen during any single attack. But in fact Larsen had spawned two in close succession, each at a critical phase during the last five minutes. Wondering whether to wait for the images to fade, Larsen remembered the revolver, in the letterbox. However irrational, it seemed his only hope. With it he would be able to test the ultimate validity of the doubles.

The outcropping ran diagonally to the edge of the apron. Crouching forwards, he scurried along it, pausing at intervals to follow the scene. The two doubles were still holding their positions, though Bayliss had closed his window and disappeared.

Larsen reached the edge of the apron, which was built on a shallow table about a foot off the desert floor, and moved along its rim to where an old fifty-gallon drum gave him a vantage point. To reach the revolver he decided to go round the far side of Bayliss's chalet, where he would find his own doorway unguarded except for the double watching by the garage.

He was about to step forward when something made him look over his shoulder.

Running straight towards him along the outcropping, head down, hands almost touching the ground, was an enormous ratlike creature. Every ten or fifteen yards it paused for a moment, and looked out at the chalets, and Larsen caught a glimpse of its face, insane and terrified, another replica of his own.

'Larsen! Larsen!'

Bayliss stood by the chalet, waving out at the desert.

Larsen glanced back at the phantom hurtling towards him, now only thirty feet away, then jumped up and lurched helplessly across to Bayliss.

Bayliss caught him firmly with his hands. 'Larsen, what's the matter with you? Are you having an attack?'

Larsen gestured at the figures around him. 'Stop them, Bayliss, for God's sake,' he gasped. 'I can't get away from them.'

Bayliss shook him roughly. 'You can see more than one? Where are they? Show me.'

Larsen pointed at the two figures hovering luminously near the chalet, then waved limply in the direction of the desert. 'By the garage, and over there along the wall. There's another hiding along that ridge.'

Bayliss seized him by the arm. 'Come on, man, you've got to face up to them, it's no use running.' He tried to drag Larsen towards the garage, but Larsen slipped down on to the concrete.

'I can't, Bayliss, believe me. There's a gun in my letterbox. Get it for me. It's the only way.'

Bayliss hesitated, looking down at Larsen. 'All right. Try to hold on.'

Larsen pointed to the far corner of Bayliss's chalet. 'I'll wait over there for you.'

As Bayliss ran off he hobbled towards the corner. Halfway there he tripped across the remains of a ladder lying on the ground and twisted his right ankle between two of the rungs.

Clasping his foot, he sat down just as Bayliss appeared between the chalets, the revolver in his hand. He looked around for Larsen, who cleared his throat to call him.

Before he could open his mouth he saw the double who had followed him along the ridge leap up from behind the drum and stumble up to Bayliss across the concrete floor. He was dishevelled and exhausted, jacket almost off his shoulders, the tie knot under one ear. The image was still pursuing him, dogging his footsteps like an obsessed shadow.

Larsen tried to call to Bayliss again, but something he saw choked the voice in his throat.

Bayliss was looking at his double.

Larsen stood up, feeling a sudden premonition of terror. He tried to wave to Bayliss, but the latter was watching the double intently as it pointed to the figures near by, nodding to it in apparent agreement.

'Bayliss!'

The shot drowned his cry. Bayliss had fired somewhere between the garages, and the echo of the shot bounded among the chalets. The double was still beside him, pointing in all directions. Bayliss raised the revolver and fired again. The sound slammed across the concrete, making Larsen feel stunned and sick.

Now Bayliss too was seeing simultaneous images, not of himself but of Larsen, on whom his mind had been focusing for the past weeks. A repetition of Larsen stumbling over to him and pointing at the phantoms was being repeated in Bayliss's mind, at the exact moment when he had returned with the revolver and was searching for a target.

Larsen started to crawl away, trying to reach the corner. A third shot roared through the air, the flash reflected in the bathroom window.

He had almost reached the corner when he heard Bayliss shout. Leaning one hand against the wall, he looked back.

Mouth open, Bayliss was staring wildly at him, the revolver clenched like a bomb in his hand. Beside him the bluesuited figure stood quietly, straightening its tie. At last Bayliss had realized he could see two images of Larsen, one beside him, the other twenty feet away against the chalet.

But how was he to know which was the real Larsen?

Staring at Larsen, he seemed unable to decide.

Then the double by his shoulder raised one arm and pointed at Larsen, towards the corner wall to which he himself had pointed a minute earlier.

Larsen tried to shout, then hurled himself at the wall and pulled himself along it. Behind him Bayliss's feet came thudding across the concrete.

He heard only the first of the three shots.
