Introduction

Seems that back in the early 1920s, Burroughs wanted to know what Stephen King wondered about much later: Did his name on the title page alone sell the book, or would one of his yarns sell if it went out to editors under a pseudonym? Between Aug. 9-31, 1922, he wrote the novelette BEWARE! and sent it out into the world as written by “John Tyler McCulloch.” It was a flop.

Eventually, it sold to Ray Palmer at AMAZING STORIES. With Burroughs’ permission — he was a pretty easygoing fellow — this contemporary mystery/spy thriller was rewritten as science fiction, re-titled THE SCIENTIST’S REVOLT, and finally published in the pulp FANTASTIC ADVENTURES in July 1939. The Burroughs original stayed tucked away for another 35 years, not seeing publication until the July 1974, issue of THE BURROUGHS BULLETIN.

Prologue

A small pane in the leaded glass of the window tinkled to the study floor, as the bullet embedded itself in the ebony paneling behind the Emperor.

It was the first of May preceding that historic second which wiped an ancient dynasty from the throne of Assuria. For a month the imperial family had virtually been prisoners in the summer palace upon the outskirts of the capital, but they had been unmolested, and their personal safety had seemed reasonably assured until this morning.

For years the voice of the agitator and the malcontent had been heard with increasing emphasis throughout the length and breadth of the empire. "Whatever is is wrong" had been the text from which they preached. During the early weeks of April the capital had been a hotbed of revolution which had rapidly merged into the chaos of anarchy. The people had grievances, but no leader—they had only agitators, who could arouse but not control.

And then had come this first of May, when the rabble from the low quarters of the city, drunk with liquor and with blood lust, had derided the weaklings at the head of the revolution and, screaming for blood and loot, had marched upon the palace with the avowed intention of assassinating the imperial family.

All that day they had howled and hooted about the palace, held in check only by a single military unit which had remained loyal to the Emperor—the Foreign Corps, recruited among foreigners and, with few exceptions, similarly officered.

A shot, the tinkling of glass upon the study floor behind the Emperor; bits of the inlaid ivory design fell as the bullet crashed into the paneling. A fusillade of shots from the palace grounds. The steady roar of the rabble, pierced by shrieks and screams of pain and rage. The Emperor turned and surveyed the panel ruefully. "My great-grandsire brought that from Persia over a hundred years ago, Semepovski. 'So fleet the works of men, back to their earth again, ancient and holy things fade like a dream'."

As the Emperor spoke his companion had crossed the room quickly. "Come, sire!" he cried, "we must leave this apartment. That shot was intended for you."

The Emperor shook his head sadly. "But for Her Majesty, I could have wished the fellow had been a better marksman," he said.

"And the Crown Prince Alexander," Semepovski reminded him.

"It might make it easier for him," replied the Emperor. "It is I they hate. My people hate me, Semepovski—my people whom I love and to whom I have tried to be a father. But them I cannot blame. They have been deceived by lies. It is toward those who knew the truth, who lived closest to me, and for whom I did the most that I feel any bitterness. Every day they are deserting me, Semepovski—the rats and the sinking ship. I am sure of only a few of you—I could count my friends tonight upon the fingers of one hand."

Prince Michael Semepovski, Minister of War, bowed his head, for the Emperor had spoken the truth and there was no denial to be made. After a moment's silence, the Emperor spoke again.

"What do you suppose started them today?" he asked. "What brought this mob to the palace?"

"They heard last night of the birth of the Crown Prince Alexander to Her Majesty," replied Semepovski. "They pretended to see in that fact a menace to what they are pleased to call The Republic—that is why they are here, sire."

"You think they want the lives of the Empress and the Crown Prince, as well as my life?" demanded the Emperor.

Semepovski bowed. "I am sure of it, sire," he replied.

"That must be prevented at all cost," said the Emperor.

"I had thought of removing them from the palace," replied Semepovski, "but that would be difficult, even were it possible to move Her Majesty, which the physicians assure me is impossible at this time, but there is just a faint possibility that we may be able to remove the Crown Prince Alexander. I have given the matter a great deal of thought, sire, for I have apprehended just such a contingency as that which has arisen. I have a plan. It entails risk, but on the other hand, to permit the Crown Prince to remain in the palace another twelve hours would, I am confident, prove fatal."

"Your plan, Semepovski, what is it?" demanded the Emperor.

"For the past month the officers of the Foreign Corps have been quartered within the palace. Several of them are married men, and their wives are here with them. One of these women, the wife of a Lieut. Donovan, gave birth to a son two days since. She is a strong and healthy young woman and could be moved without materially endangering her health. For all the rabble know, she may have had twins."

The Emperor elevated his brows. "I see," he said, "but how could she pass out with the infants? We are all virtually prisoners here. No one may escape."

"But they do daily, sire," replied Semepovski. "The palace is filled with traitors. Not a day passes but that several desert to the enemy. We are close pressed. Only a miracle can save The Foreign Corps from absolute extermination. It would not seem strange, then, to the revolutionists, should Lieut. Donovan desert to them, for the sake of the safety of his wife and children."

For several minutes the Emperor stood with bowed head, buried in thought. The yells of the rabble rose and fell without, but at a greater distance than before, since the fusillade of shots that the soldiers had poured into the ranks of the mob in reply to the shot that had shattered the window in the Emperor's study. The irregularity of the firing now suggested the activity of snipers, rather than a concerted attack by any considerable body of men. But both the Emperor and Semepovski guessed that the mob had but withdrawn temporarily, and that when they renewed the assault it would be with increased numbers and redoubled ferocity. Sooner or later the loyal guardsmen must fall, and if aught was to be done to save the Crown Prince it must be done at once.

"Call Drovoff," said the Emperor, "and we will send for this Lieut. Donovan."

"Perhaps I had better go myself," said Semepovski. "The fewer who know of what we intend, the safer will be the secret of Prince Alexander."

"I have implicit confidence in Drovoff," replied the Emperor. "He has served me faithfully for many years."

"Pardon, sire," said Semepovski, "but the occasion is one of such tremendous moment to the dynasty that I would be untrue to the trust you repose in me, were I to remain silent—sire, I fear Drovoff; I mistrust him, I have no confidence in him."

"Why?" demanded the Emperor.

"I could substantiate no charge against him," replied Semepovski, "or I should have preferred charges long ago, yet in my heart of hearts I believe him disloyal."

"Poof!" exclaimed the Emperor. "Drovoff would die for me. Summon him, please."

Semepovski moved toward the bell cord, but with his hand upon it he turned again toward the Emperor.

"I beg of you, sire, to let me go instead."

The elder man replied with an imperious gesture toward the bell cord, and Semepovski, bowing, pulled it. A few moments later, Paul Drovoff, the Emperor's valet, entered the chamber, bowing obsequiously. He was a slender, dark man, apparently in his early thirties. His eyes were large and dreamy and set rather too far apart, while, in marked contrast to them, were his thin, aquiline nose and his straight and bloodless lips. He awaited in silence the will of his master, who stood scrutinizing him closely, as though for the first time he had seen the face of the man before him. Presently, however, the Emperor spoke.

"Drovoff," he said, "you have served me faithfully for many years. I have implicit confidence in your loyalty, and because of that I am going to place within your hands tonight the future of Assuria and the safety of the dynasty."

The man bowed low. "My life is yours to command, Your Majesty," he replied.

"Good. The mob seeks our life and that of Her Majesty, the Empress, and of the Crown Prince Alexander. Even if I could leave the palace I should not do so. Her Majesty, on account of her condition, cannot, but Prince Michael believes that we can smuggle the Crown Prince away where he may remain in safety and seclusion until my poor deluded people have recovered from the madness which grips them now."

Prince Michael Semepovski, watching intently the face of the valet, saw reflected there no emotion which might arouse the slightest suspicion, as the emperor outlined the plan which might cheat the revolutionists of the fruit of their endeavor.

Twenty minutes later Drovoff returned with Lieutenant Terrance Donovan, a young Irish soldier of fortune who had been a Lieutenant in the Foreign Corps for better than a year.

At the emperor's command, Prince Michael explained the plan to the officer.

"The most difficult part," he concluded, "will be in obtaining safe escort for your wife and the two infants through the drunken rabble that surrounds the palace, but that is a chance that we must take, for in their present mood the mob will spare no one once it has gained access to the palace, which now can be but a matter of hours. Once you have gained the city remain in hiding until your wife's strength is equal to travel, then leave the country. Go to America where funds will be sent you periodically for the care and education of the Crown Prince. From time to time you will receive instructions from us, but you will make no reports unless requested, nor attempt in any way to communicate with us, for only by maintaining the utmost secrecy may we hope to preserve the Crown Prince from the vengeance of the revolutionists. To prevent suspicion from attaching to you in any way upon the other side you must pursue some calling that may at least partially account for your income. His Majesty, the Emperor, Drovoff, your wife, yourself and I are the only people who will know the identity of your second twin. No other must ever know until you receive authoritative word from Assuria that the time is ripe for his return to his people. Not even the Crown Prince himself must know that he is other than your son. Do you understand fully and do you accept the commission?"

Donovan inclined his head in assent.

"We are placing in your hands the fate of Assuria," said the Emperor; "God grant that you may be true to the trust imposed upon you."

I shall not fail you, Majesty," replied the Irishman.

Twenty-four hours later the rabble overcame the remaining guards and forced its way into the palace. The fate of the emperor and his empress is not known—their bodies were never found. The rage of the revolutionists when they discovered that the infant prince had been spirited away was unbounded. But all that is history. If you are interested in it I recommend to you The Last Days of the Dynasty, by Prince Michael Semepovski, large 12mo. illus., 529 pgs., G. Strake, Ltd., London.

* * * *

It was the sixteenth of May, two weeks after the fall of the Empire, that a tiny, muffled figure, with a weight at its feet, slipped over the side of the liner Collosic bound for New York. Upon the deck, with bowed head, stood a young Irishman, and at his side, sobbing softly, his wife clutched tightly to her breast a little baby.

Twenty-two Years Later

Chapter I

Your Ma is a very sick woman, Mackie." The older man, sitting at his desk, did not raise his eyes to his son as he spoke, and the other knew that it was because he feared to reveal the emotion that lay behind them, and thus give the boy greater cause for apprehension.

"I guessed as much when I got your message, Dad," and as he spoke, Macklin Donovan arose, and walking to his father's side laid his hand affectionately and sympathetically upon the broad shoulder of the police lieutenant. "May I see her?" he asked.

"That is all, Mackie—just see her," replied his father. "She will not know you. We must be very quiet. The doctor has ordered absolute quiet."

The younger man nodded, and together they tip-toed their way upstairs to a room on the second floor.

When they returned to the den again there was a hint of moisture on the lashes of both men.

"How did you find me," asked the younger man, "through the department?"

"Yes. I telephoned Washington. You chief told me where you were."

"I am still on the Thorn case. It has got us guessing. No one in the department believes Mr. Thorn to be more than a visionary philanthropist with conservative socialistic leanings. He wants to do good with his money, but doesn't know how. At first we thought the Reds had gotten hold of him, but the more we investigate the less sure we are about it. We haven't been able to identify a single avowed radical with him, yet we are sure that there is a bunch of Assurians with whom he has frequent dealings, often secretly. His son is as much mystified as we, and almighty worried, too. You know it was he who reported the matter to the department. He thinks they are after the old man's money, and fears that they may influence him to finance some movement that will lay him liable to Federal prosecution.

"But there's another angle to the whole case—something we haven't sensed yet, even faintly; but I'm going to get it. I think I'm closer to it now than I have been at any time during the past month that I've been on the case. We came down from their summer place yesterday on Mr. Thorn's yacht and things seem to have tightened up some way from the moment we got into his town house—there's a sort of tenseness and air of mystery that wasn't manifest at 'Three Gables.' About the only new element that seems to have been infused into the affair is Thorn's butler, a fellow named Goertz, who was not at Three Gables. None of the rest of the town servants seems to count much that I can see, but this fellow Goertz I don't like. He's always pussy-footing. I can scarcely turn around without finding him behind me. I think he suspects me and is watching me accordingly. The other guests, beside myself, are Mrs. Glassock and her daughter—the Peabody Glassocks of Philadelphia, you know—and Count Saranov and his daughter. As far as the Glassocks are concerned they are out of my reckoning entirely—might as well connect young Roosevelt or Joe Cannon with Red activities as a Glassock of Philadelphia—but the Saranovs are different. They're from Assuria. He's supposed to be a political exile. I haven't a thing on him, but I've filed him in the same folder with Goertz. The girl, his daughter, is all right—very much all right, plus."

Lieutenant Terrance Donovan looked up quickly at his son and smiled. The latter grinned back at the older man, and flushed a little.

"Don't be too sure about anybody, Mackie," counseled the father. "The best friend I had when I was walkin' beat tried to stab me in the back one night when we were raidin' a joint in the old Tenderloin. And, anent that, are you sure about young Thorn?"

"He was the best friend I had in Harvard," replied the son. "He asked to have me assigned to this case because he and I could work together better than strangers. He has done everything to aid me. Not a soul in the house knows who I really am. Thorn was afraid to even let 'em know that my father is a police lieutenant, for fear it might arouse suspicion as to my motives for being there. They think you're a retired sugar king from San Francisco and that we're lousy with money. Say, if Mrs. Peabody Glassock of Philadelphia knew the truth she'd throw a conniption."

The older man's face sobered, reflectively. "I'll say she would," he said, "-if she knew the truth."

"Well, Dad," said the boy, rising, "I've got to go—that's the hell of a job like mine, and yours, too; our personal interests mustn't count. Kipling's Tommy has nothing on us:

"'You 'aven't got no families when servin' of the Queen&mdash;

"'You 'aven't got no brothers, fathers, sisters, wives, or sons&mdash;

"'If you want to win your battles, take an' work your bloomin' guns!'"

He threw an arm about his father's shoulders affectionately. "Buck up, Dad," he said. "I'm sure Mother'll pull through all right. Keep me posted, and if I can see her when she's conscious, why—well, to Hell with the Queen. I'll come."

As he walked down the street he nodded pleasantly to the policeman at the corner who was guarding one end of the block that had been roped off against traffic to insure quiet for the sick woman lying unconscious on the second floor of the Donovan home. The cross street was covered with a layer of tan bark and as he felt it soft beneath his silent tread a realization of the reason for its being there brought a lump to his throat. "Mother!" he murmured, and then, shaking himself, stepped briskly to a waiting taxi at the opposite curb and was driven rapidly south toward an older part of the city.

The cab stopped, at last, in front of a tall, brown-stone house—one of several identical houses in a hideous, frowning block of them. Once upon a time each of them had housed a family of fashion and wealth, and even now some of the old timers remained in a few of them&mdash;men who, like Mason B. Thorn, had been born there. As Macklin Donovan mounted the steps the door was opened by a footman, just beyond whom Donovan saw Goertz, who bowed low&mdash;much too low the Secret Service man thought -- as he stepped forward to take the guest's hat.

"Mr. Thorn and the others are in the library, sir," said Goertz.

"Thank you," responded Donovan, curtly. At the library doorway he turned quickly to see Goertz's eyes upon him. Instantly the butler turned away. There was a frown on the young man's face as he entered the room.

"My!" exclaimed a tall, blonde girl; "whatever in the world is peeving our little Mackie?"

Donovan smiled as the others looked toward him. "Happy as a lark," he answered the girl. "Sun's awful out—been frowning all afternoon to keep my eyes from sunburning—haven't got my face straightened out yet."

Count Boris Saranov was standing upon the opposite side of the room facing him. Donovan was distinctly aware that Saranov's eyes were looking past him and not at him, as were the eyes of the other occupants of the library. As he advanced into the room he drew his cigarette case from his pocket and as he did so let it drop to the floor behind him. With a laughing exclamation at his awkwardness he turned quickly to pick up the case, permitting his glance to pass swiftly toward the doorway through which he had just entered the room, and the hall beyond. Goertz was standing in the shadows of the hallway, a finger raised. As Donovan turned back toward the room he was still smiling—but he was the only one who knew why.

"We're not going back to Three Gables tomorrow, Macklin," announced his host. "Genevive has had enough of New York in the summer time."

"I thought a little of it would go a long way with her when she asked you to bring her," replied Donovan, smiling. "You are returning with us?"

The elder Thorn nodded. "Got my business all attended to. Shall be glad to get out of this devilish heat."

"Hmph!" exclaimed Miss Euphonia Thorn, his sister. "You haven't transacted a bit of business. Why in the world you wanted to drag us all down here this time of year is quite beyond me. Make us all suffer for nothing—absolutely nothing. Business—hmph!"

"I didn't drag you down, Euphonia. As a matter of fact I tried to persuade you not to come. I know how you hate the city in summer. And as for my business, I'm a fast worker," he added with a laugh. "I'll finish up the tag ends after the rest of you are in bed tonight." He glanced at Saranov and then relapsed into silence. Donovan was certain that the Assurian had shot a quick warning from those deep-set, somber eyes.

"Well!" snapped Euphonia, rising. "I'm going to dress for dinner, and I think the rest of you had better be doing the same."

"Why, it isn't four thirty yet, Aunt Phony," exclaimed Percy Thorn.

"I don't care what time it is, and I wish you wouldn't call me Aunt Phony—it's vulgar and disrespectful. If your Grandfather was alive, but then --"

"But then—he isn't. Have a cigaret, Auntie?"

"You know I never smoke. I don't approve of women smoking. You just ask that to annoy me. It is a filthy habit that I have never acquired."

"I didn't know that you had ever acquired any filthy habits, Auntie. But then it is a wise nephew who knows his own aunt, these days."

The angular little woman moved majestically toward the doorway. Near it she turned and faced her brother. "Mason," she announced, "I shall not remain to be insulted farther."

Her brother laughed indulgently. "See you at dinner, Eu," he called after her.

"You can sneak a smoke now, Genevive," said Percy to the tall blonde.

"I have not ceased smoking," replied the girl with a shrug. "I do not take your Aunt Euphonia seriously."

"No one does except herself," replied the young man.

"I wish you would cease smoking occasionally, Genevive," reproved her mother. "Nariva never smokes, although she comes from a country where the women have smoked for generations, and she seems to be just as happy."

"But I do not enjoy smoking," exclaimed Miss Saranov. "I'm sure that I should smoke if I did enjoy it."

The tall Miss Glassock arose from her chair, languidly, and walked to Donovan's side. "Do you think I smoke too much, Mackie?" she inquired, purringly, placing a hand softly upon his arm.

Mrs. Glassock beamed. "Oh, those children!" she exclaimed. "It doesn't make any difference what I think, or what anyone else thinks, as long as Mackie thinks it's all right." If she sought to suggest vexation she was not entirely convincing.

Macklin Donovan was visibly ill at ease for an instant, but he laughed it off quickly. Percy Thorn appeared bored and irritated. Could looks wither, Mrs. Peabody Glassock would have assumed the dimensions of a peanut, but she did not even guess that Percy Thorn was looking at her.

Donovan petted Genevive's hand where it lay upon his sleeve. "I'm sure you wouldn't do anything too much, Gene," he assured her.

Saranov cast a quick glance at his daughter, caught her eye, and directed a furtive and very meaningful look toward Miss Glassock and Donovan. Nariva Saranov merely raised her delicate brows.

A little later the three women went to their rooms to dress. Saranov excused himself presently and was soon followed by the elder Thorn. Then Percy Thorn turned to Donovan.

"Look here, Mack," he said. "What is there between you and Gene? I want to know."

"Nothing, you old fool, except the Donovan millions," and the speaker laughed. "Can't you see that she doesn't give a tinker's dam for me—that it's her mother who is egging her on?"

"I think she's in love with you," insisted Thorn.

"I want to see 'em when they learn the truth about me," said Donovan.

"You may be right about the old lady—she's after Dad for his bank roll; but Gene—never! She's true blue, Mack. She's the real thing, and it just about does me up to see her falling in love with one of my best friends."

"Well, you ought to know your friends, Perce—if they're not fit associates for Gene you ought not to bring 'em around."

"Cut the comedy! I'm in love with her and you're not—at least you say you're not, though I don't see how you can help being—and I don't want to lose her, and I don't want to play second fiddle."

"Don't worry, Perce. It won't be for long now, unless I miss my guess. Things are coming to a head mighty quick. I have an idea that I'll learn a lot before I'm many hours older, and it may be that I can fade away then in a hurry and not gum up your love affairs with my filthy millions."

"It isn't the money, Mack—she's in love with you, I'm afraid. I've got money enough, as far as that's concerned; but she can't even see me when you're around."

"You mean when Mamma's around," corrected Donovan. "I saw her making eyes at you and rubbing up against you there at Three Gables and on the yacht every time Mamma wasn't looking."

Thorn shook his head. "I wish you were right," he said, "but you ain't. Come on, let's go up and dress." He arose and walked toward the door.

"I'll be up in a minute—you run along," replied Donovan. "I want to look around for a bit."

Thorn nodded and ran up the stairs that, descending from the second floor, opened into the large library. When he had gone Donovan walked quickly to the doorway leading to the hall. As he did so the heavy hangings before a doorway on the opposite side from the library moved, but the hall was dark and Donovan did not see the movement. He had scarcely reached the doorway when his attention was attracted by the sound of light footsteps on the stairway above. Turning quickly, he saw Nariva Saranov descending. She had halted almost at the instant that he turned, but immediately resumed her downward course. Had he surprised her? Would she have turned back had he not discovered her? He wondered.

"Ah, Mister Donovan!" she exclaimed. "I thought everyone had gone to his room. I did not expect to meet anyone," she flushed prettily.

He realized now why she might have wished to turn back unseen—she was in a negligée. A very beautiful creation that set off her dark loveliness bewitchingly. Donovan stood with one hand upon the newel post as the girl descended—his back toward the hall doorway.

"I left a little bag down here," she explained. "It contained a few trinkets that I should not care to lose. Ah, there it is!" and she crossed quickly to the chair in which she had been sitting and picked up a small gold bag. As she returned to the stairway, where Donovan still stood, she paused on the lower step. "You had better hurry and dress for dinner, Mr. Donovan," she said, with her pretty accent, "or you will be late." As she spoke she played with the little gold bag, opening it and closing it. Donovan was aware of a very delicate and delectable fragrance about her.

"What a wonderful perfume," he remarked.

The girl smiled and opened the bag again. "Yes," she said, drawing a small jeweled phial from the receptacle and holding it toward his face, "it is very wonderful. The emperor of Assuria, before he was assassinated, gave it to my—to a friend of my father. There is no more like it in all the world. It is very old and has never been uncorked, yet it permeates whatever it comes in contact with. I just took it from my trunk today—you did not notice it before?"

"There was too much smoke in the room, I guess," he replied. Suddenly he placed his hand upon hers. "I wanted to say this afternoon, but I couldn't very well at the time, that I am glad you do not smoke."

For just an instant an eager light shone in her eyes, and then she drew back.

"I am glad," she said gently, "if I have pleased Mister Donovan."

"Pleased me! Oh, Nariva, you must know -- " he drew her suddenly close to him—"you must have seen that I -- "

Quickly she place a cool, soft palm across his lips. "Stop!" she cried, and her eyes looked frightened.

The heavy hangings upon the opposite side of the hallway moved. Donovan's back was toward them.

He clung to her. "I love you!" he cried, almost angrily, it seemed. "You must have known it—you must have! Why can't you love me?"

She broke away. "Mon dieu!" she explained; "I do love you!" but there was horror in her eyes and in her voice as she turned and fled up the stairway.

Donovan looked after her for a moment with puzzled eyes, and then, passing his palm slowly across the back of his neck, he slowly ascended the stairs toward his room.

"The more you see of 'em, the less you know about 'em," he soliloquized as he closed his bedroom door behind him.

In a room at the opposite end of the house and upon the other side of the hall Miss Glassock's maid was arranging her mistress's hair, while Mrs. Glassock sat before a dressing table appliquéing her face. "At your age I should have had him long before this," Mrs. Glassock was remarking. "The girl of today lacks subtlety of contrivance in such matters."

Her daughter shrugged her fair shoulders. "I don't want him," she said. "I want Percy. I should think the Thorn millions would be enough."

"Genevive, you are vulgar!" her mother rebuked. "And anyway, if I marry Mr. Thorn I can expect nothing more than my dower rights in the event of his death, since Percy will inherit the bulk of the fortune; while Mr. Donovan, being an only child, I am told, will inherit his father's entire estate—a matter of some hundreds of millions."

Across the hall from the Glassocks Nariva Saranov stood before her mirror, scowling. In the doorway of her closet stood Count Boris Saranov. He, too, was scowling.

"You had him then," he said in a low voice, accusingly.

The girl made no reply.

"Do not fail us again," said Saranov—his tones were well modulated, but ugly. Then he stepped back into the closet and closed the door.

Nariva, her head upon one side, listened for a moment, then, almost fiercely, she pressed the back of her hand to her eyes, as one in pain. "I can't! I can't!" she murmured.

Chapter II

It was after one o'clock the following morning before they returned from supper and dancing at one of the city's popular roof gardens. Goertz admitted them. As she passed him Nariva Saranov raised her brows questioningly and the butler replied with an almost imperceptible inclination of his head. Neither act would have been noticeable to other than specially trained senses—such as Donovan's. It was his business to notice such trivial occurrences and this one did not escape him. He was puzzled and vexed—vexed with himself that he could still doubt Nariva Saranov's connection with the band of conspirators that he felt he was at last closing in upon after weeks of seemingly fruitless effort.

He had always suspected Saranov and at first had assumed that the Assurian's daughter was criminally connected with the band of which her father was a part. Reasoning from this premise it was not strange that he should seek to ingratiate himself with the girl, that through her he might gain the knowledge he sought. To this end he sought her companionship with a view to establishing friendly and intimate relations, that might develop into something closer, if necessary to his ends. The result had been that not only had he been unable to connect her with any of the activities that he believed chargeable to the band under investigation, but he had fallen hopelessly in love with her. And so he was puzzled and vexed as he walked down the hallway toward the library with the others.

After a few moments desultory conversation in which no one seemed interested Miss Thorn announced her intention of retiring—a suggestion that evidently met with the approval of the others, who, with sleepy "Good nights," ascended the stairway to their several chambers. Fifteen minutes later Goertz made the rounds of the lower floor, turning off all the lights with the exception of a small night lamp in the front hallway and a second small lamp in the library, which was the last room to which he gave his attention. Instead of returning to the servants' stairway at the rear of the house which he should have used in going to his room on the fourth floor, he ascended the main stairway from the library. He left a light on the landing about half way up the stairs, but shut off all those in the hallway on the second floor, which was, however, slightly illuminated by the light from the landing. These duties attended to he paused for a moment in the center of the hall, apparently listening. He looked quickly first in one direction and then in the other, after which, seemingly satisfied, he ascended the second flight of steps to the third floor where were located the apartments of the family. Ordinarily a small passenger elevator was used to reach the upper floors, but this was temporarily out of commission while undergoing its annual summer overhauling during the absence of the family at Three Gables. From the third floor a single flight of stairs led to the servants' quarters on the floor above.

This stairway was near the read end of the third floor hallway. Directly opposite it was a small, dark closet wherein were kept a various assortment of brooms, brushes, mops, dusters, vacuum cleaners and similar paraphernalia.

Goertz turned out all but a single light in the third floor hall, walked to the foot of the stairway, paused, listened, and then, turning quickly, crossed the hall silently, opened the door of the dark closet, entered it and closed the door after him.

Macklin Donovan had gone directly to his room, removed his dinner coat, tie and collar, and sat down to smoke and read at a table near one of the open windows which overlooked the small garden in the rear of the house. Outside this window was a narrow iron balcony identical with those outside every other window on this floor, both front and rear. These balconies did not connect with those adjacent to them, being separated by a space of about three feet. The houses upon either side were similarly disfigured by these mid-Victorian atrocities.

Macklin's back was toward the open window and he was facing in the direction of the door leading into the hallway. He was not particularly interested in the book he was reading -- it did not hold his attention. It was better than nothing, however, in assisting him to pass the time until the household slumbered, for he had a suspicion that something might transpire thereafter that would prove of interest to him and to his chief in Washington.

He had been sitting thus for about half an hour, occasionally looking up from his uninteresting book to draw upon his cigaret, when his eyes alighted upon a folded paper lying on the threshold partially inside the room. It had not been there a moment before, of that he was positive. There had been no sound—the paper had not been there one minute—the next minute it had. That was all there was to it.

In the instant that he discovered the thing he leaped quickly toward the door with the intention of throwing it open; but before his hand touched the knob he thought better of his contemplated act and, instead, stooped and picked up the paper. Whoever put it there did not want to be seen. Perhaps it would be better to humor them, temporarily at least.

Standing near the door he opened the message and read its contents, after which he was glad that he had not yielded to his first impulse to rush into the hall in an effort to discover the messenger. The note was in a feminine hand and read: "Mackie: Please come to my room at quarter past two. I have something to tell you. Do not come before," and it was signed with the initials "N. S."

Donovan's right palm went to the back of his neck in a characteristic gesture of perplexity. It wasn't like Nariva—she wasn't the sort of girl that would ask a man to her room at that hour of the morning—unless—ah, that was it! She wanted to tell him something that she didn't dare tell him before Saranov. It must be that. It must be something urgent. Whatever it was, it was all right—he could trust her—of that he was quite sure. He glanced at his watch. It lacked about five minutes to quarter past. He went to his dressing room, buttoned on his collar, adjusted his tie, and slipped into his dinner coat.

As he re-entered his room a figure in a dressing gown was cautiously descending the stairway from the third floor, pausing occasionally to listen. At the foot of the stairs it halted and glanced quickly up and down the hall the light in which was too dim to reveal the features of the nocturnal prowler. Discovering no one, the muffled figure crept stealthily along the dark hallway toward the front of the house.

As Donovan entered his room he turned immediately to his dresser from which he took an automatic pistol, which he was on the point of slipping into a hip pocket when he hesitated, held the pistol in front of him in the palm of his hand for an instant and then, with a smile and a shrug, replaced it in the dresser and closed the drawer. As he walked toward the hall door his eyes fell upon the table as he passed it. He came to an abrupt stop and, wheeling, took a hurried survey of the room, for propped against the reading lamp was a square blue envelope that had not been there when he had quitted the room a few minutes before. Snatching it up he saw his own initials crudely printed upon its face. The flap, which was but freshly sealed, he tore open, revealing an ordinary square correspondence card, upon which was printed in the same rude hand a single word: BEWARE!

A frown creased Donovan's brow. His hall door was locked. He glanced toward the open window, and then quickly at his watch. It was exactly quarter past two. Slipping the blue envelope and the card into his pocket he crossed the room to the hall door. As he laid his hand upon the knob the report of a firearm reverberated through the house, followed almost immediately by the sound of a body falling, and the piercing shriek of a woman.

Throwing the door open Donovan stepped out into the hall and ran quickly toward the front of the house—the direction from which the shot had sounded. At the head of the stairs leading to the library he stumbled over a huddled heap covered by a dressing gown. A few feet farther along the hall was Nariva Saranov's room on one side and across from it that occupied by Mrs. Glassock and her daughter. From this position of the body Donovan's police instinct sensed almost intuitively the fact that the shot could have been fired from inside Nariva's room, but not from the Glassocks' room. Too, it might also have been fired from the doorway of the room occupied by Count Boris Saranov; but from the direction that the doors of the various rooms opened it could most easily have been fired from Nariva's, had the door been opened not more than an inch, by one standing concealed within. Some of these things came to him as suspicions at the moment, to be verified by investigation later. But above all else there loomed above him like a hideous specter the appalling fact that the shot had been fired precisely at quarter past two.

Saranov was the first on the scene, followed quickly by Percy Thorn and Goertz. Goertz and Saranov were fully dressed—a fact which no one but Donovan seemed to note. It was Saranov who switched on the lights.

"What has happened?" he cried.

Donovan pointed at the huddled form lying on the floor, the head and face of which were hidden by the large collar of the dressing gown that had fallen across them as the body had slumped to the floor. "Murder!" he replied.

Saranov looked bewildered; and as Goertz came running up his eyes were wide with astonishment and incredulity, but they were not looking at the body on the floor—they were fixed on Macklin Donovan.

Mrs. Glassock now came from her room, and behind her was Genevive, while servants were pouring from the upper floors.

"Who is it?" demanded Percy Thorn.

Donovan stooped and drew back the collar of the dressing gown. A scream broke from the lips of Mrs. Glassock. "My God!" she cried, "it's Mason."

"Father!" exclaimed Percy Thorn, dropping to his knees beside the body. "Who could have done it?" he cried. "Who could have done it?" and he looked around at them all standing there—questioningly, accusingly.

Donovan knelt beside Percy and turned the body over on its back, opened the dressing gown and the shirt and placed his ear above the heart. Presently he arose. They were all looking at him, eyes filled with suspense. Donovan shook his head, sadly.

"Mr. Thorn is dead," he said. "Goertz, go to the phone and call the police. Percy, we shall have to leave the body here until they come. You had better go and prepare your aunt, and prevent her coming down until after the police have been here. I shall remain here. The rest of you may go to your rooms, or not, as you wish. There is nothing that anyone can do until after the police come."

Percy Thorn came to his feet like one in a trance and moved slowly down the hall toward the stairs leading to the third floor where was his aunt's room. Goertz ran quickly down the stairs to the library to the telephone. Donovan looked about him. Where was Nariva Saranov?

"Mrs. Glassock," he said, turning to that lady, "will you kindly step to Miss Saranov's room and see if she is all right?"

Mrs. Glassock crossed the hall and knocked lightly on Miss Saranov's door. There was no response. She knocked again, more imperatively. Still no response.

"Try the door," directed Donovan. It was locked. Donovan turned toward Saranov. "Where is your daughter?" he demanded. He was no longer the suave young society man. Instead, his voice cut like steel, and in it was the ring of steel.

Saranov was pale. "She must be in her room," he replied. "Where else could she be?"

Donovan motioned to a couple of frightened footmen. "Break down the door!" he commanded.

As they stepped forward to obey, the door of Nariva Saranov's room opened, revealing her standing there, fully dressed, and breathing rapidly. At sight of Macklin Donovan she voiced a little cry that she tried to smother, and her eyes went very wide—as had Goertz's eyes.

"What has happened?" she cried, when she found her voice. "I heard a shot and I must have swooned. Who is it?" and she looked down at the still figure on the floor. "Oh, no!" she cried when she recognized the features, "it cannot be—it cannot be Mr. Thorn—it must be a terrible mistake!"

"It was a terrible mistake, Miss Saranov," said Donovan, coldly, his eyes steadily upon hers.

Chapter III

The police came, and, as Fate would have it, under the command of Lieutenant Terrance Donovan, and after the arrival of the deputy coroner the body of Mason B. Thorn was removed to the small room off the library—a room that he had used for a study and in which was a large couch. It was laid upon the couch, near an open window. Then Terrance Donovan returned to the library. Mrs. Glassock was there, and Genevive. Percy Thorn sat on a sofa beside his aunt, who was weeping softly, trying to comfort her. Saranov stood before the cold fireplace smoking a cigaret. Goertz remained beside the door to his master's study. There were three burly police officers and some of the maids and housemen, also, the latter standing near the hall doorway as though momentarily expecting to be banished.

"Now," said Terrance Donovan, "I want to hear about this. Who saw the shooting?"

"No one," replied his son, "as far as I have been able to discover. We all heard the shot. It was fired at precisely a quarter past two." He glanced at Saranov, but the latter was looking at the ceiling. Nariva was not in the room. "I was the first to reach the hall. I found Mr. Thorn lying where you found him, but on his face. It was necessary fors me to turn him over to examine him for signs of life—otherwise the body was not disturbed."

Neither Lieutenant Donovan nor Macklin had given any indication of their relationship or that they were even acquainted, owing to the fact that the latter was assuming a role necessary to the successful prosecution of his investigation and that exposure at this time would doubtless nullify all that the Department had accomplished.

"Who do you think might have had reason to wish to kill Mr. Thorn?" continued Lieutenant Donovan.

"I believe that no one could have had any reason for wishing to kill him," replied Macklin. "To my knowledge he hadn't an enemy in the world and I never heard him in altercation with anyone—he was a most kind and considerate man to his friends, his acquaintances and his servants, while his son and sister, the only members of his immediate family, were devoted to him." He paused. "It is my belief, sir, that the shot that killed Mr. Thorn was intended for another." As he spoke he looked directly at Saranov whose eyes were now upon him, and was rewarded by a slight narrowing of the other's lids.

"Who followed you into the hall after the shot was fired?" asked the police official.

"I did," said Saranov. "Mr. Donovan was standing over the body of Mr. Thorn as I came from my room. The hall was but dimly lighted, yet sufficiently to permit me to see Mr. Donovan. He was putting something in his hip pocket as I opened the door of my room." The insinuation was obvious, and that it was thoroughly understood was manifest by the sound of quick intaking of breath by several of the occupants of the library—a natural reaction to mental shock and surprise.

Macklin smiled. "You better have me searched, Lieutenant," he said.

"I object to his being searched or questioned farther by this officer," protested Saranov.

"Why?" asked Lieutenant Donovan.

"Because you are his father," replied the Assurian, and the effect of this second surprise was almost equal to that of the first. The chin of Mrs. Peabody Glassock dropped for an instant, and then she smiled superciliously.

"The count must have lost his mind," she whispered to her daughter. "The very idea—Macklin Donovan the son of a common policeman!"

Genevive turned to a police officer standing behind them. "What is the lieutenant's name?" she asked.

"Terrance Donovan, mum," replied Officer McGroarty.

Mrs. Glassock appeared slightly groggy, but she was still in the ring. "Ridiculous!" she exclaimed. "He is of the Donovans of San Francisco." She looked defiantly, and crushingly, at Officer McGroarty.

"Sure, mum," said he, "an' it wasn't me that was after sayin' he wasn't—it was the djook over there," and he nodded in the direction of Saranov.

Terrance Donovan eyed the Assurian for a moment before he replied. "What makes you think this man is my son?" he demanded.

Saranov hesitated. He seemed to regret that he had made the charge. He smiled deprecatingly and spread his palms before him with a shrug. "It was a matter of no moment until now," he said. "One of the servants at Three Gables told my valet. I gave the matter no thought—scarcely believed it, in fact, until you arrived here tonight. Then I recalled."

"How does it happen that you know my name?" asked Terrance Donovan.

Saranov was evidently nonplussed by the question. He realized his mistake instantly, but it was too late to remedy it—there was no reason in the world, that he would care to have these people know of, why he should have any knowledge whatever of the existence of Lieutenant Terrance Donovan. He sought to cover his confusion by a show of anger.

"It makes no difference how I know," he snapped. "I do know, and I don't purpose permitting the murderer of my friend to escape because he is the son of a police lieutenant. I demand that some other officer pursue this investigation."

Terrance Donovan nodded. "You are right," he said. "I think Captain Bushor is here now—I just heard the front door, and he was notified at his home at the time I left the station."

"He does not deny that Macklin is his son," whispered Genevive, to her mother.

"Preposterous," said Mrs. Glassock, but she said it in a small voice—she was weakening.

"I always mistrusted him," she added; "he never impressed me as one having the air of one to the manner born, as it were."

At this juncture a large man in the uniform of a captain of police entered the room. He nodded to Lieutenant Donovan and crossed to his side. The two men whispered together in low tones for a few minutes, then Captain Bushor pointed a large forefinger at Count Boris Saranov.

"Do you accuse Mr. Macklin Donovan of the murder of Mason B. Thorn?" he asked.

"I accuse no one," replied Saranov. "I merely relate what I witnessed."

"What else did you witness beside what you have told Lieutenant Donovan?"

"After the police came, and while they were carrying Mr. Thorn's body down stairs Mr. Donovan went to his room, took a piece of paper from his pocket and burned it."

Macklin Donovan looked at the speaker in surprise. Saranov had spoken the truth, but how had he known?

"Perhaps," continued the count, "he may have hidden his pistol at the same time, provided of course that it was he who shot Mr. Thorn. If the pistol is not in his possession now it may be in his room. He should be searched and so should his room."

"Shure it's a dhirty frame," grumbled Officer McGroarty. "I've known Mackie Donovan since he was knee-high to nothin' at all, an' there ain't a sneaky hair in his head." He spoke in a whisper that was audible only to the Glassocks.

"Then you admit that he is the son of that person there," accused Mrs. Glassock. "I am not in the least surprised. I have said right along that he had a low face."

Genevive Glassock looked at her mother in wide-eyed astonishment. "I think he's wonderful," she said, "and I have changed my mind about marrying him." She could not resist the temptation to punish her mother in retaliation for the older woman's past unwelcome efforts at matchmaking.

"You will return to Philadelphia today," snapped Mrs. Glassock.

Captain Bushor was searching Macklin for a weapon—which he did not find.

"Now we'll take a look at your room," he said. "You come along," he pointed at Saranov. "The rest of you stay here. See that no one leaves the room, McGroarty."

Lieutenant Donovan glanced quickly around the library as he accompanied Bushor, Saranov and Macklin toward the stairway. "Where's the butler?" he demanded suddenly.

"Why, he was here just a moment ago," replied Percy Thorn; "perhaps he's stepped into the next room," and he pointed to the study where his father's body lay. "Goertz!" he called, but there was no response.

One of the policemen stepped into the adjoining room. "There ain't no one in there," he said, as he re-entered the library a moment later.

"Find him," directed the captain, as he led the way up the stairs with Macklin Donovan at his side.

Upon the left of the landing half way up the stairs was a tall pier glass and as Macklin ascended upon Bushor's right his eyes, turned toward the latter, who was speaking, viewed the mirror beyond the captain, whose eyes were turned away from it. Reflected in it, just for an instant, Macklin saw the shadowy figure of a woman dart into his room at the far end of the dimly lighted hall. He was upon the point of telling Bushor what he had seen when there flashed to his mind the realization that all the women in the house, save one, were in the library below, and that one was Nariva Saranov. An instant later they reached the head of the stairs in full view of the entire hallway. There had been no opportunity for whoever had entered his room to leave it. The hall had been lighted when last he passed through it after the officers had come, but now the lights were extinguished, the only illumination coming from the landing on the stairway. Who had extinguished them, and why? Possibly what he had just seen reflected in the mirror explained why.

The three men walked directly to Macklin's room, which, like the hall, was in darkness, although Donovan distinctly recalled that the lamp on the reading table had been lighted when he left the room. Just inside the doorway was a switch which operated two inverted dome lights suspended from the ceiling. Macklin pressed this switch and the room was flooded with light.

"I suggest that you make a very thorough search," said Saranov.

"When I want any suggestions from you I'll ask you for 'em," replied Bushor, tersely, and Saranov subsided, scowling.

"Got a gun, Macklin?" asked the captain.

"It's in my dresser—top drawer on the left," replied young Donovan, indicating the article of furniture with a jerk of his thumb.

Captain Bushor crossed to the dresser and opened the upper left hand drawer, in which he rummaged for a moment. "No gun here, Macklin," he said.

Macklin Donovan knitted his brows. "It was there at the instant that Mr. Thorn was shot," he said. "I had just placed it there. I do not know what has become of it."

The police officer continued to ransack the dresser, and then each of the other pieces of furniture in the two rooms and the closet. Nowhere could he find a pistol. Saranov was quite evidently restraining a desire to speak, only with the greatest difficulty. At last he could hold his peace no longer. "Why don't you search the bed?" he demanded, eagerly.

Macklin glanced quickly toward the bed, the covers at the foot of which, he noticed for the first time, were disarranged, as though they had been pulled out from the side and hastily tucked in again. Bushor examined several pieces of overstuffed furniture, apparently ignoring Saranov's suggestion, then crossed to the bed and pulled the coverings aside. One by one he removed and shook them. Finally he turned the mattress completely off the springs. Saranov was almost standing on tip-toe. There was no weapon there!

Young Donovan was looking at Saranov, upon whom he kept his eyes as much as possible, and he saw the look of blank surprise that crossed the Assurian's face when it became definitely evident that there was no pistol hidden in or about the bed.

All the time that the search had been going on Donovan had been awaiting the discovery of the person he had seen enter the room only a minute ahead of them, and as every nook and cranny was examined without revealing any hidden presence he was reduced to a state of surprise fully equaling that which Saranov had revealed when no pistol had been discovered beneath the mattress. Walking to one of the windows he looked out and examined the balconies along the front of the house—there was no one there.

They returned to the library just as the officer who had been detailed to find Goertz entered the room. "I've searched the whole house, Cap'n," he said, "an' he ain't here. The house is being watched outside, front an' back, an' there ain't no one gone out."

Bushor nodded. "Then he must be inside," he said. He turned to the company in the room. "You'll all admit that there's something peculiar about this case. I can lock you all up on suspicion, but I don't want to do that. Right now there isn't a case against anybody, and so I'll give you your choice of remaining here under guard until morning, or goin' to the station. Under the circumstances I can't make any exceptions, and I'm stretchin' a point in lettin' you stay here. Which will it be?" They unanimously chose to remain in the house, under guard. "Now go to your rooms and stay there." He walked from the room, beckoning Lieutenant Donovan to follow him. "I left 'em here," he explained in a low voice, "because I think here is the best place to trap the murderer. He's one of 'em, but I don't know which one. Don't let any one leave the house, and say, find that damned butler. See you about eight o'clock," and he departed.

Chapter IV

As the guests started toward their rooms Macklin found himself beside Mrs. Glassock and Genevive. "It has been a terrible experience for you," he said. "I hope that it has no ill effects. If I can be of any service do not hesitate to call upon me."

Mrs. Glassock's chin rose perceptibly. "The only service you can render us, young man, is to permit us to forget the humiliating position in which your imposture has placed us," and she swept majestically up the stairway.

Genevive paused beside him. "I am sorry for you, Mr. Donovan," she said, coldly; "but you have brought it upon yourself. One should not pretend to be what one is not," and she followed her mother up the stairs to their rooms.

Percy Thorn, assisting his aunt, followed them. As he passed Donovan he stopped and put a hand on the other's shoulder. "I want you to know, Mackie," he said, "that I think Saranov is a damned liar."

"Thanks," replied Donovan. "I knew you would not believe such a ridiculous charge."

"But who in the world could have done it?" asked Thorn.

Donovan shook his head. "I wish I knew," he replied.

He remained a moment, after the others had gone, to speak to his father—to ask the latest news concerning his mother, only to learn that there had been no change; then he, too, ascended the stairs toward his room. As he reached the top step the door of Nariva Saranov's room opened and he saw her standing there. It was evident that she wanted to speak to him. She held a finger to her lips, enjoining silence, at the same time motioning him toward her. He had taken but a couple of steps in her direction when the door of Saranov's room opened and he stepped into the hall. Simultaneously Nariva stepped back into her room and closed her door.

"I thought your room was at the opposite end of the hall, Mr. Donovan," said Saranov, with a slightly sarcastic inflection.

"No one should know it better than you," replied Macklin.

Saranov paled. "Keep away from my daughter's room," he said, nastily.

Macklin bowed. "She has been absent from the library since the police came," he said, "and I feared that she might be indisposed. I but wished to stop and inquire. Perhaps you can enlighten me."

"My daughter is quite well, thank you," replied Saranov, and as Donovan bowed again and turned toward his room the other watched him until he was out of sight.

Again in his room, the house restored to the normal quiet of the early morning hours, Donovan threw himself into an easy chair beside the table, and lighting a cigaret sat pondering the occurrences of the night. That which occupied him most was a mad effort to discover some means of removing all suspicion connected with the attempt that he believed had been made upon his life, from the person of Nariva Saranov. He did not want to believe that she had had any guilty part in it, and yet, try as he would to reach another, the conviction remained unalterable that she had attempted to lure him to his death, and that by chance only Mason B. Thorn had approached her door at the very instant that she had expected Donovan. It made him wince to even think it, and so he would set off each time upon a new tack in a fruitless effort to explain her various questionable actions upon some other hypothesis. But he could not explain away her evident surprise when she discovered him alive; he could not explain why she had been the last to come to the hall after the firing of the fatal shot; he could not explain why she and Goertz alone of all the company had been absent from the library during the police investigation. His judgment told him that she and Goertz and Saranov were at the bottom of the plot to kill him, yet but just now when she had attempted to speak to him Saranov had prevented. Then there was the memory of those almost tragic words that still were ringing in his ears: "Mon Dieu! I do love you!" and recollection of the horror that had been in her eyes as she voiced the cry and fled up the stairway. What did it all mean? Donovan rubbed the back of his neck with his right palm, but the movement had scarcely begun when it stopped abruptly, the man remaining with his hand on his neck in rigid immobility, his eyes glued upon the floor at the bottom of the closet door, beneath which a piece of paper was slowly being pushed into the room.

Cautiously Donovan arose from his chair and tip-toed across the room toward the closet. He made no noise as he moved—none until his hand fell upon the knob and then, in the same instant, he flung the door wide. The closet was empty. He entered it and examined every inch of it. It was absolutely empty except for a couple of suits that he had hung in it the day before. Like all the other closets in the house it was wainscoted with cedar to the same height that the rooms were paneled in various ornamental woods.

Mystified, Donovan came from the closet and locked the door, leaving the key in the lock. Then he stooped and picked up the bit of folded paper. It bore but a single word—the same word that the other message had borne—"BEWARE!"

As he stood before the closet door turning the bit of paper over and over, the while he searched his mind for an explanation as to the identity of its sender and the means by which he had been able to shove it from under the closet door without being in the closet, his attention was attracted by what seemed to be a shuffling sound from one of the balconies before the windows on the opposite side of the room. Cautiously he raised his eyes toward the window. The light from the reading lamp illuminated the table, the chair beside it, and a little area of the floor surrounding the two, leaving the balance of the room in a subdued light.

Beyond the table was the window from which the sound seemed to come. As he watched he thought that he saw something move upon the balcony just outside the window. He remained very quiet, apparently examining the paper in his hand, his eyes barely raised to the window. Again he saw the movement without—a human hand reached forth toward the sash. It clutched the bottom in an attempt to raise it higher, but the sash did not move. Then another hand appeared, perhaps to help. In the second hand was a long, slim dagger. The second hand never reached the sash. There was a shot. The hands disappeared. The tinkle of metal on stone. A curse. Silence.

Donovan leaped for the window, threw it open and stepped out onto the balcony. There was no one there—there was no one on any of the other balconies. A rich Irish voice rose from below. "Phwat the divil's wrong up there?" it demanded. Its owner was one of the officers left to guard the rear of the house.

"I thought I heard a shot," said Donovan. He said nothing about the figure on his balcony, for he had determined to ferret out the mysteries of that night, unaided. If Nariva was involved he wanted to know it first, and shield her, if he could. Love and insanity merely have different names.

He stooped and examined the stone floor of the balcony. There lay the dagger. He picked it up and carried it into his room. He could hear people running through the hall, aroused and alarmed by this second shot. He heard the gruff, low tones of the police, and the high, frightened voices of women. He carried the dagger to the table and held it close to the light. His face was very near it as he examined it minutely. It was a weapon of foreign make, its velvet grip bound with cords of gold. A faint fragrance wafted to his nostrils. Quickly he raised the grip closer to them and inhaled, then he let the weapon fall to the table as his hand dropped limply at his side. His face was drawn and white—the hilt was scented with Nariva Saranov's perfume.

For a moment he stood thus, then he turned and walked quickly to the door, opened it and stepped into the hall. He wanted to see who was there—or, more particularly, who was not. They were all there—Saranov, Nariva, the Glassocks, servants and police. Percy Thorn came down a moment later, his aunt behind him. Goertz alone was absent. No one seemed able to explain the shot and Donovan kept silent as to what had transpired upon his balcony and within his room.

Tired, haggard, nerve wracked, the occupants of the house returned once more to their rooms. Macklin threw himself upon his bed, fully dressed, after switching off the lights. He did not intend to sleep. He had wanted to wait until the house quieted, if it ever did, that he might, in comparative safety from discovery, go to Saranov's door and listen. He had an idea that Goertz was in there, and he wanted to make sure. But he was very tired—almost exhausted—and he dozed before he realized the danger. It could have been for but an instant before his sleep was shattered by a piercing scream, and, again, a shot rang through the house.

Macklin leaped from his bed and ran toward the hall door; as he did so, from the closet door on the opposite side of the room, a pistol flashed in the dark and a bullet whizzed by his head. As he had no weapon he could not return the fire, but he sprang to the switch and turned on the lights. Then he wheeled and faced the closet door. It was closed and the key was still upon the outside, where he had left it. He crossed the room and tried the knob—the door was locked!

As he entered the hall again he found it filled with nervous men and terrified women. Everyone was talking at once. Only the police were near normal, and even their nerves were a bit on edge.

Lieutenant Terrance Donovan was among them. "Who's missing, Macklin?" he demanded of his son.

"The butler, Count Saranov, and his daughter," replied young Donovan.

"The butler is not on the premises," said his father. "Which is Count Saranov's room?"

"Here," said Macklin, leading the way. The others crowded in their rear.

Lieutenant Donovan opened the door and fumbled for the light switch. His son stepped past him and found it, flooding the room with light. "Look!" he exclaimed, and pointed toward the closet.

There, on the floor, his body in the room, his legs extended into the closet, lay Count Boris Saranov, upon his back, blood running from a bullet wound in his forehead. Macklin Donovan turned and ran toward the hall.

"Miss Saranov!" he cried. "Something may have happened to her."

His father followed him, and again the others swarmed behind. Macklin knocked upon the girl's door—there was no response. He knocked again --louder. Silence. Motioning the others aside he stepped back, paused, hurled himself against the door with all his weight, striking it with a shoulder. A single lamp burned upon a table. The room was empty, as were the dressing room and bath and closet.

Macklin called the girl's name aloud: "Nariva! Nariva!" but there was no response. He looked blankly at his father. "What do you make of it, Dad?" he asked.

The older man shook his head. "It's got me," he admitted; "but we'll find her—she must be in the house."

"That's what you said about Goertz," his son reminded him, "but you haven't found him yet."

"I'll search the house myself this time," replied Terrance Donovan. "I want to have a closer look at Saranov's room and the body, then we'll lock it up, and I'll go through the house."

Together they went into the hall and approached Saranov's door. It was closed—they had left it open. The elder Donovan tried the knob, but the door did not open, then he stooped and looked through the keyhole.

"The door is locked, Mackie," he said. "It is locked on the inside." He turned to one of his men. "Break it in, McGroarty," he said.

The huge Irishman had to do little more than lean against the door to send it crashing into the room. The lieutenant smiled. "There is nothing heavier than a ton of Mick," he said, and McGroarty grinned, but the smile and the grin both faded as the two officers stepped into the room, for Saranov's body was not there—only a little pool of blood marked the spot upon the floor outside the open closet door where the dead man's head had rested.

Terrance Donovan scratched his head, then he turned and looked accusingly at the company clustered in the doorway. A wide-eyed, terrified housemaid was sobbing hysterically.

"Shut up!" admonished Donovan, whose own nerves were on edge by the various happenings in this house of mystery.

"I c-can't," sobbed the girl. "If ever I lives through this night, I quits. The house is haunted. I've said so right along. The noises I've heard—my gord!"

"What noises have you heard?" demanded Lieutenant Donovan.

"Footsteps at night w'en I'd be a-comin' home late. My gord, I'd run all the way up stairs as fast as I could go, 'til I got scairt to go out o'nights."

"Footsteps where?" asked the officer.

"In these rooms where there wasn't nobody in 'em—on this floor mostly. This floor's the worst. My gord, it's awful."

"Didn't you ever tell anyone about 'em?" pursued Donovan.

"Sure! My gord, didn't I tell Mr. Goertz half a dozen times?"

"What did he say?"

"He said I was just a nervous little girl afraid of the dark—that it was all my imagination. Imagination! I suppose poor Mr. Thorn a-lyin' down stairs there dead, is imagination. An' this here dead man wot gets up an' locks his door an' vanishes—I suppose he's imagination, too. My gord!"

Donovan turned to the others. "If you would feel safer together," he said, "you may go to the library and remain there the balance of the night—it will not be long now until daylight. There are officers at both ends of the house—you will be perfectly safe there."

"I wouldn't go back to my room alone if you'd give me Broadway," said the house maid. The others appeared to feel similarly, for they moved toward the stairway and down to the library in a huddled group. There were no stragglers.

Chapter V

Lieutenant Donovan, with Macklin and McGroarty, searched the house from top to bottom—there was not a room, or closet, or cupboard that they did not investigate—but their search revealed no trace of Miss Saranov, the butler, or the body of the count. They had vanished as utterly as though they had never existed.

"It's got me," said Lieutenant Donovan.

Macklin shook his head. "There's some explanation," he said.

"Of course there is."

"And I intend to find it. Good night, Dad. I'm going to my room again."

The elder man reached into a pocket and produced an automatic pistol. "Take this, Mackie," he said, "you may be needin' it. I found it in the library table. And I'm goin' to send a couple of the boys up to sit with you."

"What for?" demanded the young man.

"I can't be tellin' you, Mackie—you wouldn't understand; but I've got my own reasons, and they're good ones. I been puttin' two and two together this night—an' they don't make eight, either."

"I can take care of myself, Dad."

"Sure you can. That's probably what Thorn and Saranov thought, too. Now look at 'em."

Macklin shrugged. "All right," he said; "but remember that I'm workin' on a case, and tell 'em not to interfere with me."

"They'll be under your orders, me boy."

Shortly after Macklin Donovan entered his room the two police officers knocked at the door.

"Make yourself at home, boys," he said as the two entered, and going to the table he brought cigars for them. "I don't want to talk, he said, after they had seated themselves and lighted their cigars; "I want to listen." They nodded.

Both the officers were sleepy and in a few minutes were half dozing. Macklin was listening and thinking. He was trying to figure some explanation that would account for the mysterious disappearance of two living inmates of the house and a dead man, and he attempted also to fathom the causes underlying his father's recent apprehension concerning his own safety. If Terrance Donovan had known all that had occurred in the house and especially in Macklin's room there would be ample grounds for his fear; but he did not. He must know something else, then, that Macklin did not know. What was it that his father could not tell him and that he would not understand? The inevitable palm went to the back of his neck, which it rubbed slowly back and forth.

Macklin sat beside the table near the window; one of the policemen sat near the corner of the dressing room, the other beside the closet door across the room. Both the officers were dozing and Macklin was deep in thought when he was startled by a sibilant "S&mdash;s&mdash;st!" from somewhere at his right. He wheeled around, facing the two officers. Neither one of them had moved, and their deep, regular breathing attested the fact that both were asleep. In the middle of the floor, between Donovan and one of the officers, lay a bit of paper rolled into a small cylinder about which was rubber band. Donovan rose and stepped quickly to the window. There was no one on any of the balconies. Then he turned to the closet door which he found still locked and the key on the outside where he had left it. He moved on tip-toe to avoid arousing the officers, and thus he investigated both his room and the bath. Finally he returned to the room where the policemen still slept and picked the piece of paper from the floor. As he unfolded it he expected to find the usual message—"Beware!"—but this was something different.

"Be quick! Get out of this room. Your life is in danger," it read, in the same crude printing that had marked the others.

One of the officers awoke just as Macklin was stuffing the paper into his pocket.

"Anything wrong?" asked the policeman. "I thought someone was walkin' 'round the room, or was I sleepin'?"

"You were sleeping all right," said Donovan, "and you can go back to sleep if you want—I'll watch."

"What's that?" whispered the officer, cocking an ear.

"Sounds like someone in Saranov's room," replied Macklin in a low tone, at the same time moving cautiously toward the door.

The sound they had heard was a subdued shuffling noise. Against the silence of the night, and coming as it did from the vacant room in which Saranov had been murdered, it induced an impression of uncanniness that both men felt, inured though they were to dangers and to mysteries. Behind Donovan came the policeman and as the former laid his hand upon the knob of the door the other officer awakened. Observing their silence and their stealthy movements at a glance he arose and followed them with equal quiet. Together the three crept out into the hallway and moved noiselessly toward Saranov's door, which stood open as it had since McGroarty had broken it in. Macklin was in the lead. He had reached the frame of the door and was on the point of looking into the interior of the room when a figure stepped from it into the hall. Instantly Macklin seized it—it was Goertz.

The butler was evidently surprised, but he remained cool. "Beg pardon, sir," he said, "but I did not see you."

"No," said Donovan, sarcastically; "but I saw you. I've been lookin' for you, Goertz."

"Oh, have you, sir?" exclaimed the butler, in his best official tones. "I am very sorry, sir. Is there anything that I can do for you, sir? I did not hear your ring—I have been in my room, sir."

"You're a damned liar, Goertz," exclaimed Donovan.

"Yes, sir!" replied the butler. "I was looking for you, sir. You must not return to that room," and he pointed along the hall towards Macklin's door.

"Why?" demanded Donovan.

"It is not safe, sir."

"Why is it not safe?"

"I cannot tell you, sir; but please believe me, it is not safe," and then he turned to the officers. "Do not allow him to return to that room, I beg of you," he insisted. "Even if you remain with him he will be a dead man within five minutes after he crosses the threshold."

Macklin Donovan stood eyeing the butler closely. The man was evidently very much in earnest, but what motives prompted the warning? Donovan had his own opinion—the gang wanted to keep him out of that room for some particular reason and they were trying to frighten him out. First by the note and now by means of Goertz. Well, he wouldn't be frightened. He saw that the butler was out of breath and that his clothing was soiled here and there with dust and cobwebs.

"Where have you been all night, Goertz?" he demanded suddenly.

"Attending to my duties," responded the butler.

"Once more, you are a liar."

"Yes, sir!"

"Where is Miss Saranov?"

"Is she not in her room, sir?"

"Where is she? Answer me!"

"You will pardon me, Mr. Donovan; but I have some other duties to attend to. I must be going," and he moved toward the stairs leading to the upper floors.

"No you don't," cried Donovan, and grabbed for the man.

Goertz dodged him and started to run. "Grab him!" cried Macklin to the officer who was nearest the butler. The big Irishman jumped in front of the fugitive and held out both ponderous hands to seize him. It was a foolish move, for it left his chin exposed; but then who would expect a middle-aged butler to be so rough? Goertz struck the policeman once without even pausing and as the latter slumped to the floor the butler leaped across his body and made for the stairway. Just as he turned into it Macklin drew his gun and fired, at the same time leaping in pursuit with the second policeman at his heels. Macklin fired again as he reached the foot of the stairs and saw Goertz disappearing at the turn half way up. Donovan was young and active. He went up those stairs three or four at a time, but when he reached the top Goertz was nowhere to be seen. Followed by the officer, Donovan ascended at a run to the fourth floor—no Goertz. He searched every apartment there and even found the scuttle that lead to the roof; but that was fastened upon the inside, precluding the possibility that Goertz had escaped in this way, even had he had time to do so in the short interval of his lead over Donovan.

Crestfallen, the two men returned to the third floor and searched it thoroughly. They were joined there by Terrance Donovan and McGroarty who had been attracted by Macklin's shooting. Young Donovan narrated the incidents of the last few minutes to his father. "He just vanished—that was all—vanished," he concluded.

Donovan senior scratched his head. "As I've said about forty times this night, Mackie, it's got me, and I've been twenty-two years on the New York police force an' seen some funny things. If I hadn't pounded on walls tonight until I've near wore all the hide off my knuckles I'd say the place was full o' phony panels, but it ain't—every wall's as solid as every other one—there ain't no air spaces nowhere. And then, too, boy, I've even paced off the length and breadth of the house and the rooms and the closets, and there's no space unaccounted for. Yes, sir—it's got me."

"It's getting me, too," said his son; "but I'm goin' to stick with it."

"You keep out of that room, though," said his father. "Better come down to the library with the others."

Macklin shook his head. "I'll go in the room across the hall from mine—that's not being used," he said.

"There ain't any of 'em being used except the library," remarked the lieutenant with a smile; "you can take your choice of a lot of rooms—but I wouldn't care for Saranov's, myself."

"Nor I," said Macklin—"there's something funny about that room."

Together they descended to the second floor. "On your way down turn the light on the landing out, Dad," said Macklin; "I want to listen up here in the dark for a while."

"Keep to your room," cautioned his father.

"If it's dark they can't see me to harm me and I can listen from my doorway without being seen," explained Macklin.

"All right," agreed his father and walked down the hallway toward the stairs leading to the library while Macklin and the two officers turned toward the room opposite that which young Donovan had formerly occupied.

Macklin turned off the remaining hall lights, leaving the second floor in utter darkness; then he entered the room with the policemen, switched on the lights there long enough for them to find chairs and then switched them off again. Before their eyes could become accustomed to the darkness he recrossed the room to the door and stepped out into the hall, making no noise. In equal silence he crossed to the door of the room he had formerly occupied. Stealthily he turned the knob and opened the door. The darkness within was solid except for the two rectangular spaces that were the windows—areas that were but faintly visible against the deeper darkness of the room. As he stood just inside the door listening, he thought that he discerned something moving on one of the balconies—just a vague suggestion of a figure without definite form or shape. It riveted his attention and held his eyes. Very softly he reached behind him and closed the door, fearing that one of the officers in the room across the hall, missing him, might switch on a light that would be sure to reveal him standing there in the doorway.

Drawing his pistol he moved slowly forward toward the window—inch by inch he moved, fearing that the slightest noise might frighten away whatever haunted this balcony. He had crossed to about the middle of the room, when, without warning, the narrow beams of a flashlight burst from the closet full upon the window toward which he had been creeping. Macklin Donovan came up standing with a gasp as his eyes rested upon what the beams of the flash light revealed beyond the window—a face pressed close against the pane—the face of Saranov, the dead man, with the blood upon its forehead.

Almost instantly the face vanished toward the left and then the flashlight swung slowly about the room, coming closer and closer to Macklin Donovan. His first impulse was to flee—there was something so uncanny about the silence and the seeming inevitableness of that grisly light searching him out in the darkness of the chamber of mystery. Then he sought to keep ahead of it, but at last it drove him into a corner where he halted and held his pistol ready. An instant later the light touched his face and stopped upon it, blinding him. Then it was that he raised his weapon and fired point-blank into its fiery eye. Instantly the light disappeared.

A moment of silence was followed by a shuffling sound, coming, apparently, from the interior of the closet—then silence again. Donovan sprang through the darkness for the closet door. Fumbling for the knob, he found it; but the door was locked, and the key, which he had left upon the outside, was gone.

Chapter VI

Slightly bewildered by the rapidity with which the events of the past few moments had followed one another, and dazed by the inexplicable mystery of the weird light that had blazed through the panels of a locked door,

Donovan hesitated briefly as he sought to adjust his reasoning faculties to the improbabilities of the facts that confronted them, and select a plan of action consistent therewith.

Long since had the call of duty merged with, or been subordinated to, an overmastering urge to discover the fate or the whereabouts of Nariva Saranov, and to determine definitely her connection with the plotters, that he might fix her responsibility in the matter of the murder of Mason B. Thorn and the attempts upon his own life. Just how far she was involved with Goertz and Saranov he could not know, and now the shooting of Saranov had helped to upset whatever theories he had commenced to entertain relative to the connection existing between the three.

If Goertz and Saranov had been in league with one another, and there was no doubt in Donovan's mind but that they had been, it seemed unlikely that Goertz should have shot Saranov, while the conclusion that Nariva had been guilty of the murder of her father was impossible of entertainment. Who, then, had shot Saranov? Was Saranov dead? The fact that he had seen and recognized the face at the window but a moment since, would have, under ordinary circumstances, settled that question definitely in the mind of so sane and intelligent a man as Macklin Donovan; but the circumstances of the past few hours had been anything but ordinary, filled as they had been with mysterious disappearances and other inexplicable and seemingly supernatural manifestations of various kinds.

Where was Nariva? Was Saranov dead? If Saranov were not dead, it was reasonable to assume that if he could find him, he could find Nariva also, since the most natural conjecture would place father and daughter near one another. But where to search for them! They had not left the Thorn home, yet they were not in the Thorn home. Already had the place been searched until there remained no unrevealed hiding place where even a cat might have concealed itself successfully from the searchers. There remained but a single tenable conclusion—all others were preposterous, unthinkable, verging on the demoniacal.

Sane judgment assured him that Saranov was not dead—that the face he had seen at the window must have been the face of a living man, and that that man was Count Boris Saranov. The thing to do, then, was to follow. He walked quickly across the room, raised the window, and stepped out upon the balcony. The apparition, or the man, whichever it had been, had disappeared to the left, so toward the left Donovan looked. Three feet away was the balcony before the windows of the dressing room and bath; beyond that, at similar intervals, the balconies of the adjoining house. Below was the small garden between the rear of the house and the garage. Nowhere, upon the balconies nor in the garden, was anyone in sight, though he knew that directly beneath him were the policemen guarding the back entrance.

Stealthily, that he might not attract the attention of the officers, Donovan climbed over the handrail and stepped to the next balcony. There he paused for a moment, listening. He heard nothing other than the subdued night noises of the city. Cautiously he made his way to the nearest balcony of the house next door. The window letting upon it was wide open. Within was darkness and silence. He threw a leg over the sill and drew himself into the interior, silently. His feet dropped softly to the floor and he stood erect. The boards were carpetless. There was a feel of vacancy about him. Although he could not see, he guessed that the chamber was unfurnished—but it was not unoccupied. Of that he had startling proof immediately.

From out of the darkness at his left came a low-toned whisper.

"Go back!" it warned. "In the name of heaven, go back before they kill you!"

For just a moment Donovan hesitated, then he turned and moved quickly across the room in the direction from which the voice had come. He walked with his left hand extended before him, in his right his automatic.

"Who are you," he demanded, "and who will kill me?"

"S—s—st!" warned the voice. "They will hear you."

Simultaneously a door at the far end of the room opened, revealing the figure of a large man silhouetted against the doorway of a lighted room across a hall.

"Is that you, Drovoff?" demanded the man in the doorway.

Beyond him Donovan caught a glimpse of several men and a woman, seated or standing about a table. At the gruff question of the man in the doorway, those who were facing him looked up, while the woman, whose back had been toward the door, turned around. Macklin Donovan caught but a fleeting glimpse of her face, as at the very instant that she turned a hand reached out of the darkness and powerful fingers seized his arm. He was jerked violently through an opening, the sides of which he could feel his body strike against as it passed between, and at the same time his pistol was wrenched from his grasp and he heard the loud voice of the man in the doorway crying: "Answer me, damn you, or I fire!"

Then a door closed behind him and there came to his ears, faintly, the muffled report of a pistol. He tried to grapple with the man who was dragging him along, half backward, through the darkness, but the man was very powerful and the whole incident lasted but a moment before he felt himself swung violently around and pushed heavily backward into the dark, where he stumbled and then sprawled headlong to the floor.

As he fell two thoughts dominated his mind—one was that he must lie very quiet for the purpose of deceiving his assailant into the belief that he was stunned, that he might thus take advantage of the other and overpower him—the other was the realization that the woman he had seen in the lighted room was Nariva Saranov.

It seemed to him that he had scarcely fallen before he heard footsteps in front of him, running toward him. He heard a door fly open, and with the click of an electric switch the room was flooded with light. He leaped to his feet then to grapple with his assailants and as he faced them he uttered an oath of astonishment and stepped back in utter incredulity. They were the two police officers whom he had left but a few minutes before in the house of the late Mason B. Thorn, next door.

Then he glanced hurriedly about the lighted room—it was the one which he had first occupied in the Thorn home, and from the window of which he had stepped a minute or two since. He was nonplussed. The policemen looked at him questioningly.

"What's happened?" asked one. "We thought we heard a scrap goin' on in here."

"No," replied Donovan, "I was just looking for something in the dark and stumbled over a rug."

"Where was the shot—did you hear it?" asked the other.

"Yes," replied Donovan; "that's what I was investigating."

The officer scratched his head. "That's funny," he said. "We looked in here the first thing after we heard the shot—we didn't see you."

"Perhaps I was on the balcony then," suggested Donovan, realizing that they referred to the shot he had fired at the light from the closet, and that they must have examined the room immediately after he had left it by way of the window. He didn't want to tell them the truth, yet. He wanted to work out some plan, if he could, to learn the truth about Nariva Saranov before he was forced to expose her to arrest and all that that would mean to her whether she was guilty of any wrongdoing or not.

"That's it," said the officer, "you must o' been on the balcony. We just looked in an' didn't see no one, an' then we searched the other rooms."

"Find anything?" asked Donovan.

"No," he replied, "an' for one I didn't want to find nothin'. I've had enough of this joint. I got so now I'm afraid I'm goin' to find something every time I poke my head into one of these rooms—an' I don't know what it's goin' to be. That's what gets me."

Donovan moved toward the hallway. Through the pall of mystery a light was breaking. What it would reveal he could scarce even guess, yet that it would illuminate several hitherto seemingly inexplicable occurrences seemed probable, and it might lead to complete revelations. It might also lead to deeper mystery, and there was even a greater chance that it might lead to death; but that was a chance that every man in the service expected to be called upon to face in the pursuance of duty.

In only one respect did the plan forming in his mind disregard the straight path of duty, and that lay in his determination to carry it through alone, notwithstanding the fact that he might enlist the cooperation of an ample force of police to assist him. Call it love, call it infatuation, call it what you will—it was this passion that he felt for Nariva Saranov that prompted him to formulate his plan in secrecy and carry it out alone. Whatever she might be, however guilty of attempts upon his life, love demanded that he give her every chance, and that he could not accomplish if he shared his suspicions with the police, even though one of them were his father, for the best of policemen appear to assume all those under suspicion as guilty until proven innocent. If he led them, as he believed he could, to her hiding place, they would arrest her with the others, and all would be thrown into jail. He must, if possible, first discover the degree of her guilt. If he found her guilty, he assured himself sternly, no consideration of love would deter him from carrying on along the straight path of duty.

As he moved toward the doorway one of the officers pointed at the floor behind him.

"There's your gun," he said. "It must have dropped out of your pocket when you did the Brodie."

"Yes," agreed Donovan, as he turned and recovered the weapon, still further mystified by the fact of its return to him.

In the hallway he met his father coming from the third floor, and called him aside. "I think I'm next to something," he whispered in a low tone. "Don't ask me any questions. I'll tell you what I want and then you tell me if you'll do it."

"Shoot," said Lieutenant Donovan.

"I want every light above the first floor shut off and a stall made that will kid anyone who may be listening into believing that all of you have gone downstairs. But instead post three or four men in this hall, in the dark, and have one close to each of the doors on this side—mine, Saranov's and his daughter's, with orders to nab anyone who comes out unless they give a countersign that we'll agree upon."

"How can anyone come out when there ain't nobody in any of these rooms?" demanded Terrance Donovan.

"I don't know," replied his son. "That's what I want to find out. The countersign can be Three Gables.. Whisper it an' all your instructions to your men—if walls ever had ears it's these walls."

"What are you goin't to do?" asked the father.

"Never mind—I told you not to ask me any questions."

The older man shook his head. "Mackie," he said, "there's something about all this night's business that I've got a hunch is hooked up with something I can't tell you about, yet. If I'm right it's all got more to do with you than it has with Mason B. Thorn. I wish you'd get out of this house an' go home. I'll send a couple of the boys with you."

Young Donovan laughed. "I supposed you'd laugh," said his father, "but I wish you'd do it, Mackie. I don't think your life's safe here."

The younger man placed a hand affectionately on his father's shoulder. "Don't worry, Dad," he said, "I can take care of myself, and even if I can't, you don't want a son of yours runnin' away from his post, do you?"

Lieutenant Terrance Donovan turned slowly away. "The lights'll be out an' the men posted in two minutes," he whispered, "an' God be with you!"

In less than the brief time he had stipulated the upper floors of the Thorn home were in darkness and Lieutenant Donovan with several of his men were descending to the first floor with considerable show of noise, that any listener might think a greater number were descending than actually were. Behind him he left three burly policemen silently guarding three doorways in the blackness of the second-floor hallway. What had become of Macklin Donovan, he did not know.

Chapter VII

Donovan stood at the foot of the stairs leading to the third floor until after the lights had been extinguished, then he quietly removed his shoes, placed them at one side of the stairway, and crept noiselessly upward through the darkness and the silence of the deserted upper stories.

Occasionally he paused to listen, then resumed his upward way until he came to the top floor, along the hallway of which he groped until his hands touched the thing he sought—the ladder leading to the scuttle in the roof. He climbed the ladder, feeling above him with one hand. The lid was on and still fastened upon the inside. He was glad of that, since it indicated that those he sought made no practice of using the scuttle in their comings and goings—a fact favorable to his plans, because it suggested that the conspirators would be less likely to think that he might use the scuttle.

Unlocking it—it was fastened with two ordinary hooks-and-eyes—he gently removed the lid, revealing the starry heavens of a summer night above, and clambered out upon the roof. Then he returned the lid to its place and crossed to a similar scuttle in the roof of the adjoining house. Just for an instant he hesitated beside it. Would it be locked? He prayed that it would not, then he stooped and tried it, gently at first, later with more force. Yes, it was fastened.

There was but a single way to overcome the difficulty—he kneeled and grasped the lower edge of the lid with both hands. Then, with all the strength of his legs and back he gave a mighty upward heave. There was just a momentary sound of tearing wood as the screw-eyes pulled from their seats and the lid came up in his hands&mdash;the scuttle lay open below him.

He stooped and listened at the yawning aperture, but no sound from below suggested that the noise he had made in removing the lid had aroused the inmates of the house. It had been necessary to take the chance, though he had not done so without weighing the possibilities of detection which it involved. He knew the noise that he would have to make might be loud, but it would be brief. If those he sought were in the house below, as he fully believed them to be, the chances were that they were on the second floor and if they heard the noise at all it was unreasonable to believe that they could locate it, or that they would locate it within the house. It would come down to them but very faintly, if at all—they would not attribute it to its real source, unless the upper floor was occupied, or he had been followed. Either of these were possibilities that he must face.

With a slight shrug he lowered himself through the small opening, groped with his feet for a ladder, found it, and descended to the floor below. Again he paused—listening. It was very dark—he could see nothing. He had learned this night that he was pitted against resourceful enemies who had all the advantage of knowing the ground thoroughly. That very instant someone might be watching him—in the next the flash of a pistol in the dark might put a period to his existence.

He stepped boldly forward to where he knew the stairs should be, for he surmised that this house was, more or less, a duplicate of the Thorn House next door, in which he was correct. He found the stairs and descended them to the next floor, stopping occasionally to listen, but on the whole moving rapidly. He came at last to the stairway leading to the second floor. Here he moved with greater caution—creeping downward slowly and with the utmost stealth. Below him, on the second floor, was a dimly diffused light and the subdued murmur of voices. Almost at the foot of the stairs he paused again, listening. Cautiously he leaned forward that he might gain a glimpse of the hallway to his right. Upon the opposite side of the hall, only a few feet away, a door stood slightly ajar. The room beyond was lighted and from its interior came the murmur of voices that he had heard.

Straining his ears he sought to catch the words themselves, but there came to him only a jumble of sounds. He must move closer. He wondered how long it would be before one of the occupants of the room emerged from it, or an absent one returned. In either event he would be immediately discovered, and he did not relish being discovered until he had learned what he wished to know. Drawing his pistol, he crossed the hall and stood close to the door, which was ajar about an inch. Now he could hear.

A man was speaking—the voice was coarse and uncultured. He spoke in the Assurian tongue. Young Donovan understood it well, and he was glad now that his father had insisted upon his learning it. He had never understood why so much stress had been laid upon languages in his education—he did not understand now. He merely was glad that he had learned Assurian as well as French, Spanish and German. There had been other things in his education that had seemed in a way bizarre—fencing, for example, and riding; two accomplishments that his father had insisted upon his gaining proficiency in. He had always thought it merely a strange fancy on the part of the elder Donovan that he should be master of such things, and have a better knowledge of the history of the Old World than of his own. He did not think these thoughts now—he was too intent upon listening.

"There is a traitor among us," the man was saying.

"Or Thorn divulged the secrets of the house to others," suggested a second voice; "that, you know, is very possible and would explain much." At the sound of the second voice Donovan raised his eyebrows, for he recognized the tones—they belonged to Goertz.

There was some grumbling, as though of dissent from the suggestion, and then the first voice spoke again. "This girl—how long have you known her, Saranov? There is something about her that reminds me of someone else. Are you very sure of her?"

"You ought to be sure of me—I have been working with you for more than a year," said a feminine voice. It was Nariva!

"The Committee recommended her," came a man's voice—Saranov's. "Beyond that I know nothing of her. Until tonight I have had no reason to mistrust her; but now! By God, someone is double-crossing us—someone tried to kill me. She is the only one who could have had a motive."

"What motive?" demanded the gruff voice of the first speaker.

"The fool is in love with him."

There was a long silence and then, suddenly an exclamation from him of the coarse voice. There was the scraping of a chair on bare boards and other sounds indicative of a seated man rising excitedly to his feet. Donovan kneeled and placed an eye close to the keyhole, revealing, in the thus circumscribed range of his vision, three of the occupants of the room. Seated at a table, her back partially toward him, Nariva Saranov was nearest the door beyond which he knelt; upon the opposite side of the table from her he could see two men. One of them was Saranov, who, seated, was looking up at the man at his right—the one whom Donovan had heard rise from his chair. The latter, a coarse, heavily-bearded foreigner, leaned forward across the table and shook a trembling finger in the face of Nariva Saranov. The fellow appeared inarticulate with rage.

Donovan could not see Goertz, nor the other occupants of the room, if there were others, except a man's hand and part of a coat sleeve resting on the table to the right of the bearded figure that faced Nariva. There might be a dozen men in the room, for aught that Macklin Donovan knew to the contrary, and he sincerely hoped that however many constituted the gang, they were all in that room—it would have been most embarrassing to have had one of them come up behind him at that moment.

He wondered what it was all about—the obviously overmastering excitement and anger of the man facing Nariva Saranov—the trembling, accusing finger—the tense silence of the others in the room. Presently the bearded one found his voice. "Spy!" he screamed. "I know you now." He turned excitedly to the right and left toward the others in the room. "You are fools!" he cried. "We are all fools, dupes. The monarchists have tricked us nicely. Do you not know who she is? Do you not know who she is?"—his voice rose almost to a shriek, as he turned upon the girl again. He leaned so far forward that his pudgy finger almost touched her face as he pointed it at her.

"You are Semepovski's daughter!" he cried, accusingly. "Think of it," he exhorted the others, "the daughter of Prince Michael Semepovski, the acknowledged leader of the monarchists, admitted for more than a year to our inner circle." He turned upon the girl again. "You deny it?" he demanded.

"Have I denied it?" she asked. Her voice was level, her mien dignified; but Donovan could see that her cheek was pale.

"You know the fate of spies?" the man continued.

The girl nodded. The man faced Saranov. "The responsibility for this is more yours than another's," he said. "Is it possible that there are two spies among us?"

"There may be two, Drovoff, but I am not one of them," replied Saranov, whose facial muscles were working in nervous anger. "She tricked me, as she did all of you; but she did not try to kill any of you. She tried to kill me, the ----," he applied a foul name to her. "For the safety of the cause, she must die. Let me, then, be her executioner."

Drovoff held up a restraining hand. "Let this thing be carried out in order," he said. "Have you anything to say, Princess?"

"What could I say to you, Drovoff, betrayer of your emperor's trust, murderer, exploiter of your fellow countrymen, traitor, that would influence you from the decision that you reached the instant that you recognized me? I am ready tonight, as I have always been, to die for Assuria and the empire."

"Then die!" cried Drovoff, flushing angrily, and nodded to Saranov.

The latter rose and as he did so he drew a pistol from his pocket. The girl rose too, and stood facing them haughtily, her head high. At the same instant Macklin Donovan pushed the door aside and stepped into the room just as Saranov raised his weapon. The secret-service man fired first. Saranov grasped at his breast, slumped forward upon the table, and then slipped to the floor.

The other occupants of the room turned surprised eyes upon the intruder—there were five men and the girl. What followed happened so quickly that it could have made but a confused impression of excited words, shots, darkness and the sound of running footsteps, upon those who participated in the rapid action of the ensuing seconds.

Drovoff uttered an exclamation of surprise as his eyes fell upon Donovan.

"Ah!" he exclaimed, exultantly, "it is he!"

"Who?" demanded another—"not --?"

"Yes," cried Drovoff—"the prince!" and then: "For Assuria! For the Republic!" he screamed, and leveled his pistol.

Donovan raised his own weapon and pulled the trigger—with no result, for the empty shell had jammed after he had shot Saranov. Simultaneously Goertz drew a gun and fired, dropping Drovoff in his tracks. Nariva leaped past Macklin to the switch beside the door and plunged the room into darkness. Someone grasped him by an arm on one side and an instant later he was seized by a second person upon the other. Drovoff was groaning. Someone cried: "Stop them! Kill them!" There was the sound of heavy shoes on bare boards, and furniture pushed about and overturned. Nariva's voice sounded in Donovan's ear. "Come quickly!" she urged in a whisper. "You can trust me—you must trust me!" He felt himself rushed along through the darkness, turning first this way and then that.

Suddenly he felt hands seize him from out of the darkness before, as he collided with an invisible form.

"Halt!" commanded a deep voice, and then, "I got 'em; give a hand here." Heavy footsteps sounded, running. Then someone switched on lights and the astonished Donovan found himself in the second-floor hallway of the Thorn house, a burly policeman grappling with him, while two more came running to the assistance of the first, and on one side of him was Nariva Saranov and on the other, Goertz.

The officer who held him looked hurt. "Why didn't ye give the countersign?" he demanded.

Terrance Donovan, leaping up the stairs from the library three at a time, came down the hall at a run. "Hang on to those two," he ordered, indicating Goertz and the girl. "Good boy, Mackie, you got 'em! That's the boy!"

"I didn't get them, though," replied young Donovan, ruefully; "they got me."

Goertz was smiling. "You needn't worry about us now, Lieutenant Donovan," he said. "We won't elude you again—there's no more need for it."

"I'll say you won't!" exclaimed Terrance Donovan; "not if I know myself, you won't. I've got you, now, and I'm goin' to keep you."

"There's something about this, Dad, that we don't understand," said Macklin. "Goertz and Miss Saranov just saved my life. But before we go into it any farther we've got to get the gang next door." He turned to Goertz. "Will you show us how you get back and forth between these houses so easily and so quickly?"

"Certainly, sir," said Goertz; "but I doubt if you will find your men now. We got the ones who counted. The other three, Petroff, Kubosk and Salitch do not count for much—they were only tools working for hire, and, as far as I know, they have committed no crimes."

"Who in hell are you, anyway?" demanded Macklin Donovan of the butler.

"Wait until we come back from next door and I will tell you everything," replied Goertz.

"Go ahead, then," commanded Lieutenant Donovan, "but I'll go with you, an' keep a good hold on you into the bargain—you may be all right but you're too damned slippery to suit me."

Goertz laughed. "All right, Lieutenant, I don't know that I can blame you," he replied.

"Mac, you stay here and see that this woman don't get away again," Terrance Donovan instructed McGroarty; "the rest of you come along with us."

Goertz led them into the room formerly occupied by Macklin. The closet door that had been locked now stood open, as the lights revealed after Goertz had switched them on. Stepping into the closet the butler took hold of a clothes-hook at the end of the closet and pushed up on it—a panel swung silently inward. Passing through the opening they found themselves in another closet, the door of which Goertz opened, leading them into a chamber corresponding with the one they had left. Here he switched on the lights, crossed the room to a door which he opened and pointed to a darkened room across the hall.

"There's where they were," he said. "We are in the house next door to Mr. Thorn's."

The police crossed the hall, entered the room and switched on the lights. Saranov's dead body lay upon the floor, where it had fallen. With the exception of a few pieces of furniture, some of which was overturned, the room was vacant and unoccupied. Goertz appeared puzzled. He turned to Macklin Donovan.

"I thought Drovoff was mortally wounded," he said. "I expected to find him dead."

Donovan nodded. "The others must have helped him to get away; but they can't be far. You'd better search the house, Dad."

"You'll find a trap door in the rear room of the basement," Goertz told them, "that opens into a tunnel leading to the garage. They've gotten away by this time. It's too bad we lost Drovoff—he's the man you want."

"Why?" demanded Lieutenant Donovan.

"It was Drovoff who murdered Mr. Thorn."

"You boys follow up as far as the garage and then report back to the library," the police officer instructed his men. "Mackie, we'll take Goertz to the library now and hear his story."

Chapter VIII

As Macklin Donovan entered the Thorn library a few moments later with Goertz, Nariva Saranov, and his father, he spoke pleasantly to the Glassocks and the Thorns. Percy Thorn returned his greeting cordially; Miss Euphonia, crushed and weeping, was too buried in her own grief to notice anyone. Genevive Glassock nodded indifferently and looked in another direction, while Mrs. Peabody Glassock, looking directly through him, failed apparently to perceive either him or his salutation; unless a slightly increased elevation of her patrician chin denoted aught to the contrary.

"It is strange," she whispered later to her daughter, "that the Thorns should have tolerated such people; but then poor Mason could not have known. It is Percy's fault—he must have gotten it from his mother; her grandfather, you know, had nothing—absolutely nothing. Ah, blood will tell—always! One can see it in that Donovan person—common, very common."

She was interrupted by Lieutenant Donovan's gruff voice. "Now, Goertz," he was saying, "if you've got anything to say I want to tell you first that it may be used against you."

"I understand," replied the butler. "In the first place, Lieutenant Donovan, it may help you to understand matters better from the first if I tell you that this young lady," he indicated Nariva Saranov with a respectful inclination of the head, "is not the daughter of Saranov. She is the Princess Nariva, daughter of Prince Michael Semepovski, whom, doubtless, you will recall."

Terrance Donovan's face betrayed the astonishment the statement induced.

"As you know, the Crown Prince Alexander of Assuria was brought to America in infancy to preserve him from the wrath of the revolutionists, who assassinated the balance of the imperial family the day following his removal from the palace. Only Prince Semepovski and the emperor's valet, Paul Drovoff, beside yourself and your wife, held the secret of the whereabouts of the Crown Prince.

"Drovoff joined the revolutionists, but he kept the secret of the Prince until recently, using his knowledge to extort money from Prince Semepovski, the head of the monarchist party. For the past three years he has been the infamous power behind the infamous government that has reduced Assuria to bankruptcy and starvation. Recently the power of the monarchist party has increased tremendously, until it now constitutes the hope of Assuria and the only menace to the criminal coterie that has for so long held the fate of the country in their bloodstained hands.

The hope of the monarchists lay in the young Crown Prince, though only a few knew that he still lived, and only one, Prince Michael Semepovski, knew where and under what name and disguise. But Drovoff knew, too, and we have been watching him closely. For that purpose the Princess Nariva and I gained access to the councils of Drovoff and his fellows. We learned that Drovoff had conceived a great ambition and to further it he brought together the malcontents from all parties and formed them into the so-called Republican Party. A coup-d'etat was planned for next month, when the present government was to be overthrown and a republic proclaimed with Drovoff provisional president. The next step was to be a dictatorship, following which Drovoff was to seize all the reins of government, announce an empire and crown himself Emperor of Assuria.

"There was every possibility for the success of his bold play. The greatest obstacle lay in the existence of a rightful heir to the throne—the Crown Prince would constitute an ever-present menace to his power. Drovoff, therefore, determined to search out the young Prince Alexander and kill him; but Drovoff was clever. Really, he trusted no one, and made no confidants. Until tonight not even we who were closest to him realized his true intentions. His party consisted of many factions all of which must be appeased. He claimed, therefore, that he was coming to America to find the Crown Prince and to prevail upon him to return to Assuria as the first president of the new republic, thus winning the confidence of both the lukewarm monarchists who had joined his forces and the out-and-out republicans as well.

"The Princess Nariva and I were sent by the true monarchists to watch him, for Prince Semepovski, naturally, feared the man's every motive. We had the greatest difficulty in locating Prince Alexander, due to the fact that his present calling is such that he was forced to assume an identity different from that which we were told would reveal him to us. None of us knew him by sight—not even Drovoff; while the Prince himself is ignorant of his true identity.

"We have searched for months. Tonight we found him. Drovoff got the first clue yesterday morning, but said nothing to us. Saranov clinched it a few minutes after Mr. Thorn was murdered, as did I, though I think Drovoff may have told Saranov earlier in the night—that, I do not know.

"Lieutenant Donovan, I do not need to tell you who the Crown Prince is, nor the gratitude that every true Assurian owes you for your faithful service to the Empire and the dynasty. I should like to be the first to salute my future emperor, but there is one who better deserves that honor." Once again he turned and bowed to the Princess Nariva. "As her father had given his fortune, so she had dedicated her life and risked it many times for the sake of the Imperial House of Assuria."

The Princess Nariva smiled and inclined her head toward Goertz, then she turned to Macklin Donovan, and, curtsying low before him, took his hand in hers and raised it to her lips. "Sire, I salute you!" she said.

Donovan grasped her arm and raised her to her feet. His face was flushed with embarrassment. He drew her close to him and threw an arm about her waist, as he turned toward Goertz.

"What is the meaning of all this idiocy?" he demanded.

"It is the truth, your majesty," replied Goertz; "Lieutenant Donovan can assure you of all that."

"I think you're all gone crazy," snapped Macklin Donovan, "and anyway all this has nothing to do with the business that interests me now—who murdered Mason B. Thorn, and why? There is a great deal more to be explained, Goertz, too. I want the history of the past few hours—not the ancient history of Assuria."

"Very well, Majesty."

"Cut the 'Majesty'!"

"Yes, Maj—yes, sir!" assented Goertz with a smile. "Yesterday morning you were followed to and from Lieutenant Donovan's home. That was evidently Drovoff's first direct clue as to your identity. He thought you a spy employed by the monarchists. When he found who you really were he told us that he had discovered that you were about to expose us to the United States Government. Of course such a step would have effectively ruined all the plans of the Republic. He said you must be killed. Princess Nariva and I tried to warn you, though we had no idea who you really were. Saranov forged the note that was slipped under your door, and that was to lure you to your death. Poor Mr. Thorn chanced to pass through the hall at the instant you were expected and the bullet that was intended for you killed him. It was fired by Drovoff from a sliding panel in the wall of the Princess' closet. Come up stairs and I will show you."

He led the way to the second floor and into the room occupied by the Princess.

"This closet," and he stepped into it, "is connected with both Saranov's closet and Saranov's room by panels similar to the one I showed you in&mdash;ah—Mr. Donovan's closet." He smiled as he pronounced the name. "There is also a similar connection between Saranov's closet and the house next door, thus giving entrance to that house from all three rooms on this side of the hall.

"Now look here," and he raised a small panel in one end of the closet, revealing a breast-high aperture a few inches square that opened into the hallway opposite the head of the stairs leading to the library. "Drovoff shot Mr. Thorn from here. He entered through Saranov's closet. The Princess, realizing that you were to be shot, hastily printed a note of warning, passed back of Drovoff, through Saranov's closet to the house next door and thence to your closet, in which there is a small look-out panel similar to this. When you went to your dressing room, she entered the outer room and placed the note on your table where you discovered it.

"After she left your room to return to her own she heard the shot and thought it was you who had been killed. She screamed, and though she was in the next house you were able to hear her scream distinctly because she chanced to be opposite an open window in the light-and-air shaft which opens between the two houses.

"Saranov, too, thought that you had been killed. Possibly he showed surprise when he discovered that it was Mr. Thorn whom Drovoff had murdered by mistake, for he certainly must have been surprised and shocked too, since Mr. Thorn was to have financed the stroke that they expected would result in giving Assuria a new government."

"What did my father have to do with it?" demanded Percy Thorn.

"Your father was very much deceived. He thought that he was aiding mankind with his money, but he was only playing into the hands of unscrupulous tricksters. I do not know all that they told him, but you may be sure that little or none of it was truth."

"Go on with the story of what happened here this night," directed Terrance Donovan.

"Well, the Princess had difficulty getting back to her room without being observed by Drovoff, and she only did reach it just as you were about to have the door broken in. She was sure you had been killed, Mr. Donovan, and she told me that she almost betrayed herself when she discovered you alive.

"After you all went to the library she returned to the house next door to watch Drovoff and the others. It was in the library that I at last realized your true identity, for I knew that the reputed son of Lieutenant Donovan was in reality Crown Prince Alexander of Assuria. I immediately hastened to the house next door and acquainted the Princess with the facts. She had just learned something else from Petroff, one of Drovoff's tools. Immediately after Mr. Thorn had been killed Saranov had gone to his room as had most of the others, and from there he had entered Mr. Donovan's room from the house next door and hidden Mr. Donovan's pistol beneath the mattress. The Princess barely had time to reach the room and remove the weapon before the police searched the room. From then on she and I had to watch you, and Saranov, and Drovoff almost constantly to prevent them from finding a way to kill you.

"At last we determined that we must tell you of your danger, but when the Princess attempted to do so in the hallway Saranov discovered her and interfered. From then on he was suspicious, and we had difficulty in even getting the little notes of warning to you.

"Saranov attempted to reach your room and stab you to death with a dagger belonging to the Princess. I tried to shoot him from an upper window, but succeeded only in hitting the dagger and knocking it from his hand. Then, a few minutes later, the Princess discovered that Saranov was planning to enter your closet and shoot you from the small panel. Distracted, she knew not what to do. It was then that she shot Saranov from his closet as he was about to enter it on his way to your closet.

"To shield herself she ran to Drovoff and told him that one of the police had killed Saranov. As there were papers on his body that Drovoff did not want to fall into the hands of the police he sent Kubosk and Salitch to carry Saranov's body into the house next door. When they had done so it was discovered that Saranov was only stunned by a scalp wound, and he soon recovered consciousness.

"At the same time that Saranov was shot Drovoff was in your closet waiting for Saranov. He heard the shot, feared interference, and fired at you through the panel in your closet door. He did not wait to note the effect of this shot, but ran for the safety of the adjoining house.

"The last time we warned you, Saranov was on his way again to get you, and the Princess had to drop the note through one of the listening holes from the dark-closet on the third floor through the ceiling of your room. At the same time I made my way to Saranov's room, determined at last that I must tell you face to face of your great danger. It was then that you caught me, sir."

"And I'd like to know how you disappeared so easily," said Donovan.

"Through a panel in the dark-closet on the third floor, sir—it is very easy, if you know this house."

"I'd like to know who had all these secret panels and things put into this house," said Percy Thorn.

"Your father did, Mr. Thorn," replied the butler. "Like any other man, he had a mania for secretiveness. He also craved romance and adventure. Most of his intrigues were entirely harmless, but he chose to work under the greatest semblance of mystery. Petroff and Kubosk were skilled cabinet-makers. It was they who did the actual work."

"Go on with what happened in the house," said Macklin.

"There is not much more to tell that you do not already know. You nearly killed Princess Nariva when you fired at the light shining from your closet. She had been hiding there, expecting either Saranov or Drovoff, or both, to come again in search of you. She dimly discerned someone on the balcony and turned the light upon them—it was Saranov, as you know. The light frightened him away.

"Then she turned the light on you to make sure that it was you and not Drovoff. When you fired at her you missed her head by scarce an inch and she left the closet, fearing you might fire again. She had already removed the key from the outside lock by the simple expedient of reaching through the small aperture in the door—the same one through which Drovoff fired, and that she used to shine the flashlight on Saranov and you.

"When you followed Saranov into the house next door it was I who dragged you into the closet and then hustled you to your own room in the Thorn house. You had a narrow escape that time, sir.

"I guess that is all, Lieutenant," Goertz concluded. "I have tried to cover every point; and now won't you explain to—an—er, his majesty who he really is?"

Wait a moment," said Terrance Donovan. "Not so fast. A week ago I could have told him, for I thought I knew. Now, I'm damned if I know. We got a letter from Prince Michael then. It told me something about his fears of a plot to assassinate Mackie, and for us to watch him very close as the time was almost ripe for him to return to Assuria.

"When I read the letter to my wife she fainted, and when she came out of the faint she suffered a stroke. She has only rallied partially a couple of times since, and then she told me something that I don't know whether to believe or not, when the condition of her mind is taken into consideration. She kept cryin': 'I can't let him go—my little Mackie, my little Mackie!' And then, just in broken bits, she told me that he is our son—that it was the Crown Prince who died on the ship comin' over; an' I always thought that it was our own boy that died."

Goertz appeared dumbfounded. "We must get the truth at any cost, sir," he said.

"Who are you?" demanded Macklin.

"He is Count Macansk," said the princess. "He was a lieutenant in the Guards at the time of the revolution, and very loyal always to the imperial family."

"Can we not go to your wife at once and explain the necessity of knowing the truth?" insisted Goertz. "The fate of Assuria hangs in the balance&mdash;the happiness and prosperity of countless millions of people."

Lieutenant Donovan hesitated. "She is close to death's door," he said.

"But your promise to the emperor!" Goertz reminded him.

"Very well, we will go," the lieutenant said, "but whether we shall question my wife or not depends upon the decision of the doctor."

It was already daylight when they entered the taxis that had been summoned to take Terrance Donovan, Count Macansk, Princess Nariva and Macklin to the bedside of Mrs. Donovan. The police lieutenant and the count occupied one of the cabs, Nariva and Macklin the other. As they drove off Mrs. Peabody Glassock turned to Percy Thorn with a sickly smile. "And to think," she said, "that you have been entertaining the future Emperor of Assuria without suspicioning his true identity! But really, didn't you notice, Percy, his distinguished and majestic mien? Quite noticeable and very impressive."

In the second cab Macklin Donovan and the Princess Nariva sat in silence that was presently broken by the man.

"Before I knew that you were a princess I told you that I loved you," he said.

"Before I knew that you were an emperor I told you that I loved you," she replied; "but now we must forget all that. You see how impossible it is."

"If I am an emperor nothing should be impossible. If I am only Mackie Donovan, the son of an Irish policeman, though, that will make the difference, for how could such aspire to the hand of a princess?"

"I pray to God that you are only Mackie Donovan, dear," she whispered, "for then I can show you how easy it is to win the hand of a princess."

He took her in his arms. "Emperor or Mick," he said, "I'm going to marry you."
