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."
"I have a cab outside."
"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' 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 favoured me with your medical views."
"I was certainly surprised to find you there."
"But not more so than I to find you."
"I came to find a friend."
"And I to find an enemy."
"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 clue in the incoherent ramblings of these sots, as I have done before now. Had I been recognised 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."
"What! You do not mean bodies?"
"Ay, bodies, Watson. We should be rich men if we had 1000 pounds for every poor devil who has been done to death in that den. It is the vilest murder-trap on the whole riverside, and I fear that Neville St. Clair has entered it never to leave it more. But our trap should be here." He put his two forefingers between his teeth and whistled shrilly--a signal which was answered by a similar whistle from the distance, followed shortly by the rattle of wheels and the clink of horses' hoofs.
"Now, Watson," said Holmes, as a tall dog-cart dashed up through the gloom, throwing out two golden tunnels of yellow light from its side lanterns. "You'll come with me, won't you?"
"If I can be of use."
"Oh, a trusty comrade is always of use; and a chronicler still more so. My room at The Cedars is a double-bedded one."
"Yes; that is Mr. St. Clair's house. I am staying there while I conduct the inquiry."
"Where is it, then?"
"Near Lee, in Kent. We have a seven-mile drive before us."
"But I am all in the dark."
"Of course you are. You'll know all about it presently. Jump up here. All right, John; we shall not need you. Here's half a crown. Look out for me to-morrow, about eleven. Give her her head. So long, then!"
He flicked the horse with his whip, and we dashed away through the endless succession of sombre and deserted streets, which widened gradually, until we were flying across a broad balustraded bridge, with the murky river flowing sluggishly beneath us. Beyond lay another dull wilderness of bricks and mortar, its silence broken only by the heavy, regular footfall of the policeman, or the songs and shouts of some belated party of revellers.
