“You can trust us to look after that, Mr. Holmes,” said Lestrade, as the whole party moved towards the door. “Anything further to say?”

“Only to ask what charge you intend to prefer?”

“What charge, sir? Why, of course, the attempted murder of Mr. Sherlock Holmes.”

“Not so, Lestrade. I do not propose to appear in the matter at all. To you, and to you only, belongs the credit of the remarkable arrest which you have effected. Yes, Lestrade, I congratulate you! With your usual happy mixture of cunning and audacity, you have got him.”

“Got him! Got whom, Mr. Holmes?”

“The man that the whole force has been seeking in vain - Colonel Sebastian Moran, who shot the Honourable Ronald Adair with an expanding bullet from an air-gun through the open window of the second-floor front of No. 427 Park Lane, upon the thirtieth of last month. That’s the charge, Lestrade. And now, Watson, if you can endure the draught from a broken window, I think that half an hour in my study over a cigar may afford you some profitable amusement.”

Our old chambers had been left unchanged through the supervision of Mycroft Holmes and the immediate care 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 observed 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 frockcoat, 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 right, 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.
