"The room in which I stood was dimly lighted, but I could see that, like the hall, it was hung with heavy, Persian rugs. The corners were filled with palms, and there was the unmistakable odor in the air of Russian cigarettes, and strange, dry scents that carried me back to the bazaars of Vladivostock. Near the front windows was a grand piano, and at the other end of the room a heavily carved screen of some black wood, picked out with ivory. The screen was overhung with a canopy of silken draperies, and formed a sort of alcove. In front of the alcove was spread the white skin of a polar bear, and set on that was one of those low, Turkish coffee-tables. It held a lighted spirit-lamp and two gold coffee-cups. I had heard no movement from above stairs, and it must have been fully three minutes that I stood waiting, noting these details of the room and wondering at the delay, and at the strange silence.

"And then, suddenly, as my eye grew more used to the half-light, I saw, projecting from behind the screen, as though it were stretched along the back of a divan, the hand of a man and the lower part of his arm. I was as startled as though I had come across a footprint on a deserted island. Evidently, the man had been sitting there since I had come into the room, even since I had entered the house, and he had heard the servant knocking upon the door. Why he had not declared himself I could not understand, but I supposed that, possibly, he was a guest, with no reason to interest himself in the Princess's other visitors, or, perhaps, for some reason, he did not wish to be observed. I could see nothing of him except his hand, but I had an unpleasant feeling that he had been peering at me through the carving in the screen, and that he still was doing so. I moved my feet noisily on the floor and said, tentatively, 'I beg your pardon.'

"There was no reply, and the hand did not stir. Apparently, the man was bent upon ignoring me, but, as all I wished was to apologize for my intrusion and to leave the house, I walked up to the alcove and peered around it. Inside the screen was a divan piled with cushions, and on the end of it nearer me the man was sitting. He was a young Englishman with light-yellow hair and a deeply bronzed face. He was seated with his arms stretched out along the back of the divan, and with his head resting against a cushion. His att.i.tude was one of complete ease. But his mouth had fallen open, and his eyes were set with an expression of utter horror. At the first glance, I saw that he was quite dead.

"For a flash of time I was too startled to act, but in the same flash I was convinced that the man had met his death from no accident, that he had not died through any ordinary failure of the laws of nature. The expression on his face was much too terrible to be misinterpreted. It spoke as eloquently as words. It told me that before the end had come he had watched his death approach and threaten him.

"I was so sure he had been murdered that I instinctively looked on the floor for the weapon, and, at the same moment, out of concern for my own safety, quickly behind me; but the silence of the house continued unbroken.

"I have seen a great number of dead men; I was on the Asiatic Station during the j.a.panese-Chinese war. I was in Port Arthur after the ma.s.sacre. So a dead man, for the single reason that he is dead, does not repel me, and, though I knew that there was no hope that this man was alive, still, for decency's sake, I felt his pulse, and, while I kept my ears alert for any sound from the floors above me, I pulled open his shirt and placed my hand upon his heart. My fingers instantly touched upon the opening of a wound, and as I withdrew them I found them wet with blood. He was in evening dress, and in the wide bosom of his shirt I found a narrow slit, so narrow that in the dim light it was scarcely discernible. The wound was no wider than the smallest blade of a pocket-knife, but when I stripped the shirt away from the chest and left it bare, I found that the weapon, narrow as it was, had been long enough to reach his heart. There is no need to tell you how I felt as I stood by the body of this boy, for he was hardly older than a boy, or of the thoughts that came into my head. I was bitterly sorry for this stranger, bitterly indignant at his murderer, and, at the same time, selfishly concerned for my own safety and for the notoriety which I saw was sure to follow. My instinct was to leave the body where it lay, and to hide myself in the fog, but I also felt that since a succession of accidents had made me the only witness to a crime, my duty was to make myself a good witness and to a.s.sist to establish the facts of this murder.

"That it might, possibly, be a suicide, and not a murder, did not disturb me for a moment. The fact that the weapon had disappeared, and the expression on the boy's face were enough to convince, at least me, that he had had no hand in his own death. I judged it, therefore, of the first importance to discover who was in the house, or, if they had escaped from it, who had been in the house before I entered it. I had seen one man leave it; but all I could tell of him was that he was a young man, that he was in evening dress, and that he had fled in such haste that he had not stopped to close the door behind him.

"The Russian servant I had found apparently asleep, and, unless he acted a part with supreme skill, he was a stupid and ignorant boor, and as innocent of the murder as myself. There was still the Russian princess whom he had expected to find, or had pretended to expect to find, in the same room with the murdered man. I judged that she must now be either upstairs with the servant, or that she had, without his knowledge, already fled from the house. When I recalled his apparently genuine surprise at not finding her in the drawing-room, this latter supposition seemed the more probable. Nevertheless, I decided that it was my duty to make a search, and after a second hurried look for the weapon among the cushions of the divan, and upon the floor, I cautiously crossed the hall and entered the dining-room.

"The single candle was still flickering in the draught, and showed only the white cloth. The rest of the room was draped in shadows. I picked up the candle, and, lifting it high above my head, moved around the corner of the table. Either my nerves were on such a stretch that no shock could strain them further, or my mind was inoculated to horrors, for I did not cry out at what I saw nor retreat from it. Immediately at my feet was the body of a beautiful woman, lying at full length upon the floor, her arms flung out on either side of her, and her white face and shoulders gleaming, dully, in the unsteady light of the candle. Around her throat was a great chain of diamonds, and the light played upon these and made them flash and blaze in tiny flames. But the woman who wore them was dead, and I was so certain as to how she had died that, without an instant's hesitation, I dropped on my knees beside her and placed my hands above her heart. My fingers again touched the thin slit of a wound. I had no doubt in my mind but that this was the Russian princess, and when I lowered the candle to her face I was a.s.sured that this was so. Her features showed the finest lines of both the Slav and the Jewess; the eyes were black, the hair blue-black and wonderfully heavy, and her skin, even in death, was rich in color. She was a surpa.s.singly beautiful woman.

"I rose and tried to light another candle with the one I held, but I found that my hand was so unsteady that I could not keep the wicks together. It was my intention to again search for this strange dagger which had been used to kill both the English boy and the beautiful princess, but before I could light the second candle I heard footsteps descending the stairs, and the Russian servant appeared in the doorway.

"My face was in darkness, or I am sure that, at the sight of it, he would have taken alarm, for at that moment I was not sure but that this man himself was the murderer. His own face was plainly visible to me in the light from the hall, and I could see that it wore an expression of dull bewilderment. I stepped quickly toward him and took a firm hold upon his wrist.

"'She is not there,' he said. 'The Princess has gone. They have all gone.'

"'Who have gone?' I demanded. 'Who else has been here?'

"'The two Englishmen,' he said.

"'What two Englishmen?' I demanded. 'What are their names?'

"The man now saw by my manner that some question of great moment hung upon his answer, and he began to protest that he did not know the names of the visitors and that until that evening he had never seen them.

"I guessed that it was my tone which frightened him, so I took my hand off his wrist and spoke less eagerly.

"'How long have they been here?' I asked, 'and when did they go?'

"He pointed behind him toward the drawing-room.

"'One sat there with the Princess,' he said; 'the other came after I had placed the coffee in the drawing-room. The two Englishmen talked together, and the Princess returned here to the table. She sat there in that chair, and I brought her cognac and cigarettes. Then I sat outside upon the bench. It was a feast-day, and I had been drinking. Pardon, Excellency, but I fell asleep. When I woke, your Excellency was standing by me, but the Princess and the two Englishmen had gone. That is all I know.'

"I believed that the man was telling me the truth. His fright had pa.s.sed, and he was now apparently puzzled, but not alarmed.

"'You must remember the names of the Englishmen,' I urged. 'Try to think. When you announced them to the Princess what name did you give?'

"At this question he exclaimed, with pleasure, and, beckoning to me, ran hurriedly down the hall and into the drawing-room. In the corner furthest from the screen was the piano, and on it was a silver tray. He picked this up and, smiling with pride at his own intelligence, pointed at two cards that lay upon it. I took them up and read the names engraved upon them."

The American paused abruptly, and glanced at the faces about him. "I read the names," he repeated. He spoke with great reluctance.

"Continue!" cried the baronet, sharply.

"I read the names," said the American with evident distaste, "and the family name of each was the same. They were the names of two brothers.

One is well known to you. It is that of the African explorer of whom this gentleman was just speaking. I mean the Earl of Chetney. The other was the name of his brother. Lord Arthur Chetney."

The men at the table fell back as though a trapdoor had fallen open at their feet.

"Lord Chetney?" they exclaimed, in chorus. They glanced at each other and back to the American, with every expression of concern and disbelief.

"It is impossible!" cried the Baronet. "Why, my dear sir, young Chetney only arrived from Africa yesterday. It was so stated in the evening papers."

The jaw of the American set in a resolute square, and he pressed his lips together.

"You are perfectly right, sir," he said, "Lord Chetney did arrive in London yesterday morning, and yesterday night I found his dead body."

The youngest member present was the first to recover. He seemed much less concerned over the ident.i.ty of the murdered man than at the interruption of the narrative.

"Oh, please let him go on!" he cried. "What happened then? You say you found two visiting-cards. How do you know which card was that of the murdered man?"

The American, before he answered, waited until the chorus of exclamations had ceased. Then he continued as though he had not been interrupted.

"The instant I read the names upon the cards," he said, "I ran to the screen and, kneeling beside the dead man, began a search through his pockets. My hand at once fell upon a card-case, and I found on all the cards it contained the t.i.tle of the Earl of Chetney. His watch and cigarette-case also bore his name. These evidences, and the fact of his bronzed skin, and that his cheek-bones were worn with fever, convinced me that the dead man was the African explorer, and the boy who had fled past me in the night was Arthur, his younger brother.

"I was so intent upon my search that I had forgotten the servant, and I was still on my knees when I heard a cry behind me. I turned, and saw the man gazing down at the body in abject horror.

"Before I could rise, he gave another cry of terror, and, flinging himself into the hall, raced toward the door to the street. I leaped after him, shouting to him to halt, but before I could reach the hall he had torn open the door, and I saw him spring out into the yellow fog. I cleared the steps in a jump and ran down the garden-walk but just as the gate clicked in front of me. I had it open on the instant, and, following the sound of the man's footsteps, I raced after him across the open street. He, also, could hear me, and he instantly stopped running, and there was absolute silence. He was so near that I almost fancied I could hear him panting, and I held my own breath to listen. But I could distinguish nothing but the dripping of the mist about us, and from far off the music of the Hungarian band, which I had heard when I first lost myself.

"All I could see was the square of light from the door I had left open behind me, and a lamp in the hall beyond it flickering in the draught.

But even as I watched it, the flame of the lamp was blown violently to and fro, and the door, caught in the same current of air, closed slowly.

I knew if it shut I could not again enter the house, and I rushed madly toward it. I believe I even shouted out, as though it were something human which I could compel to obey me, and then I caught my foot against the curb and smashed into the sidewalk. When I rose to my feet I was dizzy and half stunned, and though I thought then that I was moving toward the door, I know now that I probably turned directly from it; for, as I groped about in the night, calling frantically for the police, my fingers touched nothing but the dripping fog, and the iron railings for which I sought seemed to have melted away. For many minutes I beat the mist with my arms like one at blind man's buff, turning sharply in circles, cursing aloud at my stupidity and crying continually for help.

At last a voice answered me from the fog, and I found myself held in the circle of a policeman's lantern.

"That is the end of my adventure. What I have to tell you now is what I learned from the police.

"At the station-house to which the man guided me I related what you have just heard. I told them that the house they must at once find was one set back from the street within a radius of two hundred yards from the Knightsbridge Barracks, that within fifty yards of it someone was giving a dance to the music of a Hungarian band, and that the railings before it were as high as a man's waist and filed to a point. With that to work upon, twenty men were at once ordered out into the fog to search for the house, and Inspector Lyle himself was despatched to the home of Lord Edam, Chetney's father, with a warrant for Lord Arthur's arrest. I was thanked and dismissed on my own recognizance.

"This morning, Inspector Lyle called on me, and from him I learned the police theory of the scene I have just described.

"Apparently, I had wandered very far in the fog, for up to noon to-day the house had not been found, nor had they been able to arrest Lord Arthur. He did not return to his father's house last night, and there is no trace of him; but from what the police knew of the past lives of the people I found in that lost house, they have evolved a theory, and their theory is that the murders were committed by Lord Arthur.

"The infatuation of his elder brother, Lord Chetney, for a Russian princess, so Inspector Lyle tells me, is well known to everyone. About two years ago the Princess Zichy, as she calls herself, and he were constantly together, and Chetney informed his friends that they were about to be married. The woman was notorious in two continents, and when Lord Edam heard of his son's infatuation he appealed to the police for her record.

"It is through his having applied to them that they know so much concerning her and her relations with the Chetneys. From the police Lord Edam learned that Madame Zichy had once been a spy in the employ of the Russian Third Section, but that lately she had been repudiated by her own government and was living by her wits, by blackmail, and by her beauty. Lord Edam laid this record before his son, but Chetney either knew it already or the woman persuaded him not to believe in it, and the father and son parted in great anger. Two days later the marquis altered his will, leaving all of his money to the younger brother, Arthur.

"The t.i.tle and some of the landed property he could not keep from Chetney, but he swore if his son saw the woman again that the will should stand as it was, and he would be left without a penny.

"This was about eighteen months ago, when, apparently, Chetney tired of the Princess, and suddenly went off to shoot and explore in Central Africa. No word came from him, except that twice he was reported as having died of fever in the jungle, and finally two traders reached the coast who said they had seen his body. This was accepted by all as conclusive, and young Arthur was recognized as the heir to the Edam millions. On the strength of this supposition he at once began to borrow enormous sums from the money-lenders. This is of great importance, as the police believe it was these debts which drove him to the murder of his brother. Yesterday, as you know, Lord Chetney suddenly returned from the grave, and it was the fact that for two years he had been considered as dead which lent such importance to his return and which gave rise to those columns of detail concerning him which appeared in all the afternoon papers. But, obviously, during his absence he had not tired of the Princess Zichy, for we know that a few hours after he reached London he sought her out. His brother, who had also learned of his reappearance through the papers, probably suspected which would be the house he would first visit, and followed him there, arriving, so the Russian servant tells us, while the two were at coffee in the drawing-room. The Princess, then, we also learn from the servant, withdrew to the dining-room, leaving the brothers together. What happened one can only guess.

"Lord Arthur knew now that when it was discovered he was no longer the heir, the moneylenders would come down upon him. The police believe that he at once sought out his brother to beg for money to cover the post-obits, but that, considering the sum he needed was several hundreds of thousands of pounds, Chetney refused to give it him. No one knew that Arthur had gone to seek out his brother. They were alone. It is possible, then, that in a pa.s.sion of disappointment, and crazed with the disgrace which he saw before him, young Arthur made himself the heir beyond further question. The death of his brother would have availed nothing if the woman remained alive. It is then possible that he crossed the hall, and, with the same weapon which made him Lord Edam's heir, destroyed the solitary witness to the murder. The only other person who could have seen it was sleeping in a drunken stupor, to which fact undoubtedly he owed his life. And yet," concluded the Naval Attache, leaning forward and marking each word with his finger, "Lord Arthur blundered fatally. In his haste he left the door of the house open, so giving access to the first pa.s.ser-by, and he forgot that when he entered it he had handed his card to the servant. That piece of paper may yet send him to the gallows. In the meantime, he has disappeared completely, and somewhere, in one of the millions of streets of this great capital, in a locked and empty house, lies the body of his brother, and of the woman his brother loved, undiscovered, unburied; and with their murder unavenged."

In the discussion which followed the conclusion of the story of the Naval Attache, the gentleman with the pearl took no part. Instead, he arose, and, beckoning a servant to a far corner of the room, whispered earnestly to him until a sudden movement on the part of Sir Andrew caused him to return hurriedly to the table.
