of Mrs. Hudson. As I entered I saw, it is true, an unwonted tidiness, but the old landmarks were all in their place. There were the chemical corner and the acid-stained, deal-topped table. There upon a shelf was the row of formidable scrap-books and books of reference which many of our fellow-citizens would have been so glad to burn. The diagrams, the violin-case, and the pipe-rack—even the Persian slipper which contained the tobacco—all met my eyes as I glanced round me. There were two occupants of the room—one Mrs. Hudson, who beamed upon us both as we entered; the other the strange dummy which had played so important a part in the evening's adventures. It was a wax-coloured model of my friend, so admirably done that it was a perfect facsimile. It stood on a small pedestal table with an old dressing-gown of Holmes's so draped round it that the illusion from the street was absolutely perfect.
"I hope you preserved all precautions, Mrs. Hudson?" said Holmes.
"I went to it on my knees, sir, just as you told me."
"Excellent. You carried the thing out very well. Did you observe where the bullet went?"
"Yes, sir. I'm afraid it has spoilt your beautiful bust, for it passed right through the head and flattened itself on the wall. I picked it up from the carpet. Here it is!"
Holmes held it out to me. "A soft revolver bullet, as you perceive, Watson. There's genius in that, for who would expect to find such a thing fired from an air-gun. All right, Mrs. Hudson, I am much obliged for your assistance. And now, Watson, let me see you in your old seat once more, for there are several points which I should like to discuss with you."
He had thrown off the seedy frock-coat, and now he was the Holmes of old in the mouse-coloured dressing-gown which he took from his effigy.
"The old shikari's nerves have not lost their steadiness nor his eyes their keenness," said he, with a laugh, as he inspected the shattered forehead of his bust.
"Plumb in the middle of the back of the head and smack through the brain. He was the best shot in India, and I expect that there are few better in London. Have you heard the name?"
"No, I have not."
"Well, well, such is fame! But, then, if I remember aright, you had not heard the name of Professor James Moriarty, who had one of the great brains of the century. Just give me down my index of biographies from the shelf."
He turned over the pages lazily, leaning back in his chair and blowing great clouds from his cigar.
"My collection of M's is a fine one," said he. "Moriarty himself is enough to make any letter illustrious, and here is Morgan the poisoner, and Merridew of abominable memory, and Mathews, who knocked out my left canine in the waiting-room at Charing Cross, and, finally, here is our friend of to-night."
He handed over the book, and I read:—
"MORAN, SEBASTIAN, COLONEL. Unemployed. Formerly 1st Bengalore Pioneers. Born London, 1840. Son of Sir Augustus Moran, C.B., once British Minister to Persia. Educated Eton and Oxford. Served in Jowaki Campaign, Afghan Campaign, Charasiab (despatches), Sherpur, and Cabul. Author of 'Heavy Game of the Western Himalayas,' 1881; 'Three Months in the Jungle,' 1884. Address: Conduit Street. Clubs: The Anglo-Indian, the Tankerville, the Bagatelle Card Club."
On the margin was written, in Holmes's precise hand::—
"The second most dangerous man in London."
"This is astonishing," said I, as I handed back the volume. "The man's career is that of an honourable soldier."
"It is true," Holmes answered. "Up to a certain point he did well. He was always a man of iron nerve, and the story is still told in India how he crawled down a drain after a wounded man-eating tiger. There are some trees, Watson, which grow to a certain height and then suddenly develop some unsightly eccentricity. You will see it often in humans. I have a theory that the individual represents in his development the whole procession of his ancestors, and that such a sudden turn to good or evil stands for some strong influence which came into the line of his pedigree. The person becomes, as it were, the epitome of the history of his own family."
"It is surely rather fanciful."
"Well, I don't insist upon it. Whatever the cause, Colonel Moran began to go wrong. Without any open scandal he still made India too hot to hold him. He retired, came to London, and again acquired an evil name. It was at this time that he was sought out by Professor Moriarty, to whom for a time he was chief of the staff. Moriarty supplied him liberally with money and used him only in one or two very high-class jobs which no ordinary criminal could have undertaken. You may have some recollection of the death of Mrs. Stewart, of Lauder, in 1887. Not? Well, I am sure Moran was at the bottom of it; but nothing could be proved. So cleverly was the Colonel concealed that even when the Moriarty gang was broken up we could not incriminate him. You remember at that date, when I called upon you in your rooms, how I put up the shutters for fear of air-guns? No doubt you thought me fanciful. I knew exactly what I was doing, for I knew of the existence of this remarkable gun, and I knew also that one of the best shots in the world would be behind it. When we were in Switzerland he followed us with Moriarty, and it was undoubtedly he who gave me that evil five minutes on the Reichenbach ledge.
"You may think that I read the papers with some attention during my sojourn in France, on the look-out for any chance of laying him by the heels. So long as he was free in London my life would really not have been worth living. Night and day the shadow would have been over me, and sooner or later his chance must have come. What could I do? I could not shoot him at sight, or I should myself be in the dock. There was no use appealing to a magistrate. They cannot interfere on the strength of what would appear to them to be a wild suspicion. So I could do nothing. But I watched the criminal news, knowing that sooner or later I should get him. Then came the death of this Ronald Adair. My chance had come at last! Knowing what I did, was it not certain that Colonel Moran had done it? He had played cards with the lad; he had followed him home from the club; he had shot him through the open window. There was not a doubt of it. The bullets alone are enough to put his head in a noose. I came over at once. I was seen by the sentinel, who would, I knew, direct the Colonel's attention to my presence. He could not fail to connect my sudden return with his crime and to be terribly alarmed. I was sure that he would make an attempt to get me out of the way at once, and would bring round his murderous weapon for that purpose. I left him an excellent mark in the window, and, having warned the police that they might be needed—by the way, Watson, you spotted their presence in that doorway with unerring accuracy—I took up what seemed to me to be a judicious post for observation, never dreaming that he would choose the same spot for his attack. Now, my dear Watson, does anything remain for me to explain?"
"Yes," said I. "You have not made it clear what was Colonel Moran's motive in murdering the Honourable Ronald Adair."
"Ah! my dear Watson, there we come into those realms of conjecture where the most logical mind may be at fault. Each may form his own hypothesis upon the present evidence, and yours is as likely to be correct as mine."
"You have formed one, then?"
"I think that it is not difficult to explain the facts. It came out in evidence that Colonel Moran and young Adair had between them won a considerable amount of money. Now, Moran undoubtedly played foul—of that I have long been aware. I believe that on the day of the murder Adair had discovered that Moran was cheating. Very likely he had spoken to him privately, and had threatened to expose him unless he voluntarily resigned his membership of the club and promised not to play cards again. It is unlikely that a youngster like Adair would at once make a hideous scandal by exposing a well-known man
