"Do not trouble yourself, Miss Thurston. Only lead the way."

She unlocked the door herself. Although it was a fine, large house, there were no servants in evidence. I helped her off with her coat and hung it for her in a closet off to one side. As we ascended the front stairs, she hastily explained that another of her father's inexplicable behaviors was to give leave to the entire staff until-she supposed-the crisis had pa.s.sed.

"Oh, I do fear that it is is a mania, Mr. Holmes." a mania, Mr. Holmes."

I was beginning to fear as much myself, but scarcely a moment to consider the possibility when a voice thundered from above, "Abigail! Is that you?"

Miss Thurston looked to Holmes, then to me with an expression of utmost bewilderment and fright. I think she all but fainted at that moment. I made ready to catch her lest she tumble back down the stairs.

Again came the voice, from somewhere off to the left of the top of the stairs. "Abigail! If that's you, speak up girl! If it's Hawkins, you d.a.m.ned blackguard, I have my gun ready and am fully prepared to shoot!"

Holmes shouted in reply, "Sir Humphrey, it is Sherlock Holmes and his colleague Dr. Watson. We have been admitted by your daughter, who is here with us."

"Abigail?"

"Yes, Father, it is I. I've brought them as you asked."

Heavy footsteps crossed the floor upstairs. A door opened with a click of the lock being undone.

"Thank G.o.d, then... "

Holmes, Miss Thurston, and I were admitted into Sir Humphrey's study. I was astounded to confront the same man same man we had seen on the street. The broad shoulders, bearded face, high forehead, dark eyes, and athletic gait were unmistakable. But now he wasn't dressed for the outdoors. He wore a dressing gown and slippers. An elephant gun lay across the chair where he had obviously been sitting moments before. On the table by his right hand were a bottle and gla.s.s of brandy, a notebook, a pen and an uncapped ink jar. we had seen on the street. The broad shoulders, bearded face, high forehead, dark eyes, and athletic gait were unmistakable. But now he wasn't dressed for the outdoors. He wore a dressing gown and slippers.

On the table by his right hand were a bottle and gla.s.s of brandy, a notebook, a pen and an uncapped ink jar.

"Thank G.o.d you are here, Mr. Holmes," he said. "Doubtless my daughter has told you of my distress and seeming madness. If anyone on Earth may convince me that I am not not mad, it is you, Mr. Holmes. I can trust no one else to uncover the fiendish devices by which I have been made to see the impossible." mad, it is you, Mr. Holmes. I can trust no one else to uncover the fiendish devices by which I have been made to see the impossible."

We all sat. Thurston offered Holmes and me gla.s.ses of brandy. Holmes waved his aside. I accepted out of politeness, but after a single sip placed it on the table beside me.

Sir Humphrey seemed about ready to speak, when Holmes interrupted.

"First, a question. Have you been, for any reason, outside of the house this morning?"

Thurston looked startled. "Certainly not. I have not been out of this room room for five days-" He paused, as if uncertain of how to proceed. for five days-" He paused, as if uncertain of how to proceed.

It was Holmes's turn to be astonished, but only I, who knew him well, could detect the subtle change in his manner and expression. To the others he must have seemed, as before, calm and attentive, purely a.n.a.lytical.

The silence went on for a minute or two. Now that I had a chance to examine our surroundings, the room proved to be exactly what I expected, a cluttered a.s.sembly of mementoes and books, a large bronze Buddha seated on a teakwood stand, strangely demonic Asian masks hanging on the walls amid framed citations and photographs. In a place of honor behind his writing desk hung a portrait of a beautiful woman whose features resembled those of Abigail Thurston but were somewhat older. This I took to be her mother.

"Do go on, Sir Humphrey," said Holmes, "and tell us what has taken place during these five days in which you have never once left this room."

"You'll probably think I am out of my mind, Mr. Holmes. Indeed, I think so myself, whenever I am unable to convince myself that I am beguiled by some devilish trickery. For the life of me, I cannot figure out how it is done. done."

"How what is done, Sir Humphrey?"

"Mr. Holmes, do you know what I mean when I say I have seen my death fetch?" death fetch?"

Abigail Thurston let out a cry, then covered her mouth with her hand.

Holmes seemed unperturbed. "In the superst.i.tions of many races, a man who is about to die may encounter his spirit-likeness. The German term is doppelganger, doppelganger, meaning double-walker. Certainly such an apparition is held to be a portent of the direst sort, and to be meaning double-walker. Certainly such an apparition is held to be a portent of the direst sort, and to be touched touched by this figure means instantaneous death. You haven't been touched by it then, have you, Sir Humphrey?" by this figure means instantaneous death. You haven't been touched by it then, have you, Sir Humphrey?"

Thurston's face reddened. "If you mean to mock me, Mr. Holmes, then my faith in you is misplaced."

"I do not mock. Nor do I deal in phantoms. My practice stands firmly flat-footed upon the ground. No ghosts need apply. Therefore I must agree with your conclusion, even before I have examined the evidence, that you are the victim of trickery of some kind. But first, describe to me what you think think you have seen." you have seen."

"Myself, Mr. Holmes. My daughter has surely mentioned my sudden aversion to mirrors." Mr. Holmes. My daughter has surely mentioned my sudden aversion to mirrors."

"Don't we all see ourselves in mirrors?"

"I saw myself twice." twice."

"Twice?"

"Five mornings ago, I stood before the mirror shaving, when a second image appeared in the gla.s.s, as if an exact duplicate of myself exact duplicate of myself were looking over my shoulder. I whirled about, razor in hand, and confronted were looking over my shoulder. I whirled about, razor in hand, and confronted myself myself as surely as if I gazed into a second mirror, only the face of this as surely as if I gazed into a second mirror, only the face of this other other was contorted with the most venomous hatred, Mr. Holmes, the most absolute malevolence I have ever beheld. The lips were about to form an utterance which I somehow was contorted with the most venomous hatred, Mr. Holmes, the most absolute malevolence I have ever beheld. The lips were about to form an utterance which I somehow know know would mean my immediate death. would mean my immediate death.

"So I slashed frantically with my razor. I felt the blade pa.s.s through only the air, but the figure vanished, like a burst soap bubble."

"And it did not harm you in any way," said Holmes, "any more than a soap bubble-or some projected illusion of light and shadow."

"Oh no, Mr. Holmes, this was no magic-lantern show. It was a fully three-dimensional image. Each time I saw it, it was as real to my eyes as you and Dr. Watson appear now."

"You saw it, then, more than once?"

"Three times, Mr. Holmes, until I had the sense to remove all mirrors and reflective surfaces from the room. That is how it gets in. gets in. I am certain of that." I am certain of that."

"And I am certain, Sir Humphrey, that you you are certain of far more than you have told me. Unless you give me are certain of far more than you have told me. Unless you give me all all of the facts, I cannot help you, however much your daughter may entreat me. Who, for instance, is the 'blackguard Hawkins' you took us for on the stairs?" of the facts, I cannot help you, however much your daughter may entreat me. Who, for instance, is the 'blackguard Hawkins' you took us for on the stairs?"

Thurston refilled his gla.s.s and took a long draught of brandy, then settled back. "Yes, you are right, of course, Mr. Holmes. I shall have to tell you and Dr. Watson everything." He turned to his daughter. "But you, my dear, perhaps should not hear what we have to say."

"Father, I think I am old enough."

"It is not a pretty story."

"My early years were wild," Sir Humphrey began. "I was no paragon of scientific respectability at twenty-one, but little more than a common criminal. I have never before admitted that I was dismissed from the Indian Army under extremely disreputable circ.u.mstances and only escaped court martial because a sympathetic officer allowed me time to flee, change my name, and disappear. The offense involved the pillage of a native temple, and the officer's sympathy had been purchased with some of the loot.

"And so, under another name, I wandered the East. I had no means by which to return to England, nor had I any desire to present myself to friends and family as a failure and a disgrace. Once in a very great while I dispatched a letter filled with fanciful, if artfully vague, tales of confidential adventures in government service.

"In the course of my travels I picked up several languages and a profound education in the ways of the world's wickedness. I fell in with the roughest possible company, and was myself more often than not on the wrong side of the law. In the gold fields of Australia there was a certain dispute and a man died of it, and once more I had to vanish. In Shanghai I worked as an agent for a wealthy mandarin, whose true activities, when they became known to the Chinese authorities, caused his head to be pickled in brine.

"But the blackest depths were in Rangoon, for there I met Wendall Hawkins. He was a vile rogue, Mr. Holmes, even among such company as I found him. Murderer, thief, pirate, and more-I am sure. He was a huge, powerful man with an enormous, dark beard, who used to jokingly boast-though I think he half believed it-that he was the reincarnation of Edward Teach, the notorious buccaneer commonly known as Blackbeard.

"Reckless as I was, my normal instinct would have been to avoid such a man as I would a live cobra, but he had something which fascinated me: an idol six inches in height, of a hideous, bat-winged dog, carven of the finest milky green jade, stylized in a manner which resembled the Chinese but wasn't. Its eyes were purest sapphires.

"Mr. Holmes, I was more than just a thieving lout in those days. Already the direction of my life's work was clear to me-though I had yet to learn its manner-for if ever I suffered from a true mania, it was the craving to penetrate the deepest secrets of the mysterious Orient. Oh, I wanted riches, yes, but more than that I hoped to come back to England famous, like some Burton or Livingstone or Speke, having brought the light of European science to the darkest and most forbidden corners of the globe.

"I knew what this idol was, even before Wendall Hawkins told me. It was an artifact of the Chan-Tzo people who inhabit the Plateau of Leng in central Asia, in that unmapped and unexplored region northwest of Tibet, where theoretically the Chinese and Russian empires adjoin, but in fact no civilized person has ever set foot-for all the ravings of Madame Blavatsky contain much nonsense about the place. The very name, Chan-Tzo, is often mistranslated as 'Corpse-Eaters,' and so occultists whisper fearfully of the hideous rites of the 'Corpse Eating Cult of Leng.' In truth necrophagia is the least of Leng's horrors. The Chan-Tzo are 'Vomiters of Souls'... but I am far ahead of myself.

"Hawkins had the idol and he had a map-which had been acquired, he darkly hinted, at the cost of several lives-written in an obscure Burmese dialect. He needed me to translate. That was why he had come to me. Otherwise he would share his treasure-hunt with as few as possible-for that was what it was to be. We would journey to Leng armed to the teeth, slaughter any natives who stood in our way, and return to civilization rich men. I tried to console my conscience with the belief that I, at least, would be travelling as much for knowledge as for wealth, and that through my efforts this find could be of scientific value.

"Hawkins and ten others had pooled funds to buy a steam launch, which we christened, to suit our leader's fancy, the Queen Anne's Revenge Queen Anne's Revenge. Once we had secured sufficient ammunition and supplies, we slipped up the Irrawaddy by night and journeyed deep into the interior, beyond the reach of any colonial authorities, ultimately anchoring at Putao near the Chinese border and continuing overland.

"I don't have to tell you that the trip was a disaster. Supplies went bad or disappeared. We all had fevers. What native guides we could hire or seize at gunpoint misled us, then got away. I alone could read the d.a.m.ned map, but it was cryptic, even if you could make out the script. Much of the time I merely guessed and tried to find our way by the stars.

"Many times I was certain that none of us would get back alive. The first to die was the crazy American, something-or-other Jones, a lunatic who carried a bullwhip and fancied himself an archaeologist. We found Jones in his tent, bloated to half again normal size, his face eaten away by foot-long jungle leeches.

"One by one the others perished, from accidents, from disease that might have been poisoning. Gutzman, the South African, caught a dart in the neck one night. Van Eysen, the Dutchman, tried to make off with most of our remaining food and clean water. Hawkins shot him in the back, then killed the Malay when he protested, and the Lascar on general principles. Another Englishman, Gunn, got his throat cut merely so that there would be one mouth less to feed.

"Since I alone could read the map-or pretended to-I was certain Hawkins needed me alive. In the end, there were only the two of us, ragged and emaciated wretches staggering on in a timeless delirium of pain and dread. It was nothing less than a living death.

"At last we emerged from the jungle and climbed onto the windswept tableland of central Asia. Still the journey seemed endless. I had no idea of where we were going anymore, for all I made a show of consulting the map over and over so that Hawkins would not kill me. Each night I dreamed of the black and forbidding Plateau of Leng, which was revealed to me in a series of visions, its ruins and artificial caverns of shocking antiquity, perhaps older even than mankind itself, as were the immemorial blasphemies of the Chan-Tzo.

"What Hawkins dreamed, I cannot say. His speech had ceased to be coherent, except on the point of threatening me should I waver from our purpose. I knew he was insane then, and that I would die with him, likewise insane, unless I could somehow escape his company.

"I was past thinking clearly. How fortunate, then, that my plan was simplicity itself-almost the bare truth rather than some contrived stratagem.

"I fell to the ground and refused to rise, no matter how much Hawkins screamed that he would blow my brains out with his pistol. I said I was dying, that his pistol would be a mercy. He He would offer me no mercy. I was counting on that. Instead, he forced me to translate the map for him and make notes as best I could. There was nothing to write with by a thorn and my own blood, but I wrote, and when he was satisfied, he laughed, folded the map into his pocket, took would offer me no mercy. I was counting on that. Instead, he forced me to translate the map for him and make notes as best I could. There was nothing to write with by a thorn and my own blood, but I wrote, and when he was satisfied, he laughed, folded the map into his pocket, took all all our remaining supplies, and left me to my fate on the trackless, endless plain. our remaining supplies, and left me to my fate on the trackless, endless plain.

"And so we parted. I hoped I had sent him to h.e.l.l, deliberately mixing up the directions so he'd end up only the Devil knew where. He, of course, a.s.sumed I would be vulture's meat before another day or two.

"But I did not die. Mad with fever and privation, my mind filled with fantastic and horrible hallucinations, I wandered for what might have been days or even weeks, until, by the kindness of providence alone, I stumbled into the camp of some nomads, who, seeing that I was a white man, bore me on camel-back into the Chinese province of Sinkiang and there turned me over to a trader, who brought me to a missionary.

"This proved to be my salvation, both physical and otherwise. I married the missionary's daughter, Abigail's mother, and largely through the influence of her family I later found a place on a much more respectable Anglo-French expedition to Angkor. That was the true beginning of my scientific career. Still the mysteries of the East haunted me, but my cravings were directed into proper channels until I achieved the renown I have today."

At this point Sir Humphrey paused. The only sound was the slow ticking of a great clock in some other room. Abigail Thurston's face was white from the shock of what she had heard. She scarcely seemed to breathe. Holmes sat very still, his chin held in his hand, staring into s.p.a.ce.

I was the one who broke the silence.

"Surely, Sir Humphrey, there is more to the story than that. I don't see how your luckless expedition or whatever fate the rascal Hawkins must have met has anything to do with the here and now."

Thurston's reaction was explosive.

"d.a.m.n it, man! It has everything everything to do with my predicament and what may well be my inevitable fate. But... you are right. There is more to tell. After many years of roving the world, giving lectures, publishing books, after I was knighted by the Queen-after my past life seemed a bad dream from which I had finally awakened-I thought I was safe. But it was not to be. to do with my predicament and what may well be my inevitable fate. But... you are right. There is more to tell. After many years of roving the world, giving lectures, publishing books, after I was knighted by the Queen-after my past life seemed a bad dream from which I had finally awakened-I thought I was safe. But it was not to be. This past fortnight I began to receive communications from the fiend Hawkins!" This past fortnight I began to receive communications from the fiend Hawkins!"

"Communications?" said Holmes. "How so?"

"There. On the desk."

Holmes reached over and opened an ornately carven, lacquered box, removing a sheaf of papers. He glanced at them briefly and gave them to me.

"What do you make of them, Watson?"

"I cannot read the writing. The paper is an Oriental rice-paper. The penmanship shows the author to be under considerable mental strain, perhaps intoxicated. Notice the frequent scratchings and blottings. Beyond that, I can make out nothing."

Sir Humphrey spoke. "The language is an archaic-some would say degenerate-form of Burmese, the script a kind of code used by criminals in the Far East. Between these two elements, I am perhaps the only living living man who can read what is written here, for Wendall Hawkins man who can read what is written here, for Wendall Hawkins is not alive is not alive, if his words are to be believed."

"Surely if he is dead," said Holmes, "your troubles are at an end."

"No, Mr. Holmes, they are not, for all of these letters were written after after Hawkins's death-long after it. It seems that he Hawkins's death-long after it. It seems that he reached reached the Plateau of Leng, which I saw only in visions. There the almost sub-human priests of the Chan-Tzo murdered him after what might have been the Plateau of Leng, which I saw only in visions. There the almost sub-human priests of the Chan-Tzo murdered him after what might have been years years of indescribable tortures, then brought him back into a kind of half-life as an animate corpse at their command, hideously disfigured, the skin flayed from his face, his heart ripped out, the cavity in his chest filled with inextinguishable fire. He is implacable now, driven both by the will of his masters and his own rage for revenge against me, whom he blames for his unending agony. He knows all the secrets of the Chan-Tzo priests, and the conjuring of death-fetches is easily within his power." of indescribable tortures, then brought him back into a kind of half-life as an animate corpse at their command, hideously disfigured, the skin flayed from his face, his heart ripped out, the cavity in his chest filled with inextinguishable fire. He is implacable now, driven both by the will of his masters and his own rage for revenge against me, whom he blames for his unending agony. He knows all the secrets of the Chan-Tzo priests, and the conjuring of death-fetches is easily within his power."

"He says all that that in these letters?" I asked. in these letters?" I asked.

"That and more, Dr. Watson, and if it is true, I am defenseless. My only hope is that Mr. Holmes and yourself can prove me to be deluded, deluded, the victim of a the victim of a hoax hoax perpetrated by the vile Hawkins who has no doubt returned, but returned, I still dare to hope, as no more than a mortal villain. If you can do this, I certainly have the means to reward you handsomely for your services." perpetrated by the vile Hawkins who has no doubt returned, but returned, I still dare to hope, as no more than a mortal villain. If you can do this, I certainly have the means to reward you handsomely for your services."

"My services are charged on a fixed scale," said Holmes, "but let us not concern ourselves with the monetary details now. I shall indeed collar this Hawkins for you and unmask his devices-which I am sure would make the tricks of our English spirit mediums child's play in comparison-but they are devices none the less. For what else can they be?"

"Mr. Holmes, I will be forever in your debt."

"We shall watch and wait until Hawkins is forced to show his hand. But first, I think Dr. Watson should escort Miss Abigail to a safer place, my own rooms, which I shall not be needing until this affair is concluded." When Thurston's daughter made to protest, Holmes turned to her and said, "You have been a heroine, but now that the battle is actually joined, I think it best that you remove yourself from the field. Will you go with Dr. Watson?"

"Whatever you say, Mr. Holmes."

"Splendid. Now I must busy myself examining the house inside and out, to discover any way our enemy might use to gain entrance."

Thurston picked up the elephant gun and lay it across his lap, then began idly polishing the barrel with a cloth.

"I've survived five days like this. I think I shall be safe here behind the locked door for a little while longer yet. Your plan makes excellent sense, Mr. Holmes."

We left Sir Humphrey alone in the room. As Holmes and I escorted Miss Thurston down the stairs, the detective asked me, "Well, Watson, what do you think?"

"A unique case, Holmes. One worthy of your talents."

"About Sir Humphrey. What about him?"

"I judge him to be of fundamentally sound mind, but what superst.i.tious fears he may harbor are being played upon by the murderous Hawkins, who sounds himself to be completely mad."

"Mad or not, he shall have to manifest himself in a decidedly material material form before long, at which point he will be susceptible to capture by mundane means." form before long, at which point he will be susceptible to capture by mundane means."

"One thing doesn't fit, Holmes. Who, or what, did we see upon our arrival here? Sir Humphrey hadn't been out of the room."

"An impostor, possibly a trained actor in league with Hawkins. I agree that all the pieces of the puzzle are not yet in place. But have patience. You know my methods."

"I am so glad that you and Dr. Watson will help Father," Miss Thurston said softly as we reached the base of the stairs. "You are sent from Heaven, both of you."

Holmes smiled indulgently. "Not from nearly so far, but we shall do what we can."

Alas, we could do but little. As we stood there at the base of the stairs and I helped Miss Thurston on with her coat, she turned and chanced to look back up the stairs. Suddenly she screamed.

"Good G.o.d!" I exclaimed.

Near the top of the stairs was a figure who appeared to be Sir Humphrey, but dressed for the outside, in coat and top hat, as we had seen him before. He could not could not have gotten past us. have gotten past us.

"You! Stop!" Holmes was already in pursuit, bounding up the steps three at a time.
