“Ask Mr. Sholto to step this way.—Mr. Sholto, it is my duty to inform you that anything which you may say will be used against you. I arrest you in the Queen’s name as being concerned in the death of your brother.”

“There, now! Didn’t I tell you!” cried the poor little man, throwing out his hands, and looking from one to the other of us.

“Don’t trouble yourself about it, Mr. Sholto,” said Holmes. “I think that I can engage to clear you of the charge.”

“Don’t promise too much, Mr. Theorist,—don’t promise too much!” snapped the detective. “You may find it a harder matter than you think.”

“Not only will I clear him, Mr. Jones, but I will make you a free present of the name and description of one of the two people who were in this room last night. His name, I have every reason to believe, is Jonathan Small. He is a poorly-educated man, small, active, with his right leg off, and wearing a wooden stump which is worn away upon the inner side. His left boot has a coarse, square-toed sole, with an iron band round the heel. He is a middle-aged man, much sunburned, and has been a convict. These few indications may be of some assistance to you, coupled with the fact that there is a good deal of skin missing from the palm of his hand. The other man—”

“Ah! the other man—?” asked Athelney Jones, in a sneering voice, but impressed none the less, as I could easily see, by the precision of the other’s manner.

“Is a rather curious person,” said Sherlock Holmes, turning upon his heel. “I hope before very long to be able to introduce you to the pair of them.—A word with you, Watson.”

He led me out to the head of the stair. “This unexpected occurrence,” he said, “has caused us rather to lose sight of the original purpose of our journey.”

“I have just been thinking so,” I answered. “It is not right that Miss Morstan should remain in this stricken house.”

“No. You must escort her home. She lives with Mrs. Cecil Forrester, in Lower Camberwell: so it is not very far. I will wait for you here if you will drive out again. Or perhaps you are too tired?”

“By no means. I don’t think I could rest until I know more of this fantastic business. I have seen something of the rough side of life, but I give you my word that this quick succession of strange surprises to-night has shaken my nerve completely. I should like, however, to see the matter through with you, now that I have got so far.”
