“Holmes!” I whispered, “what on earth are you doing in this den?”
“As low as you can,” he answered; “I have excellent ears. If you would have the great kindness to get rid of that sottish friend of yours I should be exceedingly glad to have a little talk with you.”
“Then pray send him home in it. You may safely trust him, for he appears to be too limp to get into any mischief. I should recommend you also to send a note by the cabman to your wife to say that you have thrown in your lot with me. If you will wait outside, I shall be with you in five minutes.”
It was difficult to refuse any of Sherlock Holmes’s requests, for they were always so exceedingly definite, and put forward with such a quiet air of mastery. I felt, however, that when Whitney was once confined in the cab my mission was practically accomplished, and for the rest, I could not wish anything better than to be associated with my friend in one of those singular adventures which were the normal condition of his existence. In a few minutes I had written my note, paid Whitney’s bill, led him out to the cab, and seen him driven through the darkness. In a very short time a decrepit figure had emerged from the opium den, and I was walking down the street with Sherlock Holmes. For two streets he shuffled along with a bent back and an uncertain foot. Then, glancing quickly round, he straightened himself out and burst into a hearty fit of laughter.
“I suppose, Watson,” said he, “that you imagine that I have added opium-smoking to cocaine injections, and all the other little weaknesses on which you have favored me with your medical views.”
“I was certainly surprised to find you there.”
“Yes; one of my natural enemies, or, shall I say, my natural prey. Briefly, Watson, I am in the midst of a very remarkable inquiry, and I have hoped to find a clew in the incoherent ramblings of these sots, as I have done before now. Had I been recognized in that den my life would not have been worth an hour’s purchase; for I have used it before now for my own purposes, and the rascally Lascar who runs it has sworn to have vengeance upon me. There is a trap-door at the back of that building, near the corner of Paul’s Wharf, which could tell some strange tales of what has passed through it upon the moonless nights.”
