“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.”

“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’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 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.”

“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 clew 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[55] 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.”

“The Cedars?”

“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. A dull wrack was drifting slowly across the sky, and a star or two twinkled dimly here and there through the rifts of the clouds. Holmes drove in silence, with his head sunk upon his breast, and the air of a man who is lost in thought, while I sat beside him, curious to learn what this new quest might be which seemed to tax his powers so sorely, and yet afraid to break in upon the current of his thoughts. We had driven several miles, and were beginning to get to the fringe of the belt of suburban villas, when he shook himself, shrugged his shoulders, and lit up his pipe with the air of a man who has satisfied himself that he is acting for the best.

“You have a grand gift of silence, Watson,” said he. “It makes you quite invaluable as a companion. ‘Pon my word, it is a great thing for me to have someone to talk to, for my own thoughts are not over-pleasant. I was wondering what I should say to this dear little woman to-night when she meets me at the door.”

“You forget that I know nothing about it.”

“I shall just have time to tell you the facts of the case before we get to Lee. It seems absurdly simple, and yet, somehow I can get nothing to go upon. There’s plenty of thread, no doubt, but I can’t get the end of it into my hand. Now, I’ll state the case clearly and concisely to you, Watson, and maybe you can see a spark where all is dark to me.”

“Proceed, then.”

“Some years ago – to be definite, in May, 1884 – there came to Lee a gentleman, Neville St. Clair by name, who appeared to have plenty of money. He took a large villa, laid out the grounds very nicely, and lived generally in good style. By degrees he made friends in the neighbourhood, and in 1887 he married the daughter of a local brewer, by whom he now has two children. He had no occupation, but was interested in several companies and went into town as a rule in the morning, returning by the 5:14 from Cannon Street[56] every night. Mr. St. Clair is now thirty-seven years of age, is a man of temperate habits, a good husband, a very affectionate father, and a man who is popular with all who know him. I may add that his whole debts at the present moment, as far as we have been able to ascertain amount to 88 pounds 10s,[57] while he has 220 pounds standing to his credit in the Capital and Counties Bank. There is no reason, therefore, to think that money troubles have been weighing upon his mind.

“Last Monday Mr. Neville St. Clair went into town rather earlier than usual, remarking before he started that he had two important commissions to perform, and that he would bring his little boy home a box of bricks. Now, by the merest chance, his wife received a telegram upon this same Monday, very shortly after his departure, to the effect that a small parcel of considerable value which she had been expecting was waiting for her at the offices of the Aberdeen Shipping Company. Now, if you are well up in your London, you will know that the office of the company is in Fresno Street, which branches out of Upper Swandam Lane, where you found me to-night. Mrs. St. Clair had her lunch, started for the City, did some shopping, proceeded to the company’s office, got her packet, and found herself at exactly 4:35 walking through Swandam Lane on her way back to the station. Have you followed me so far?”

“It is very clear.”

“If you remember, Monday was an exceedingly hot day, and Mrs. St. Clair walked slowly, glancing about in the hope of seeing a cab, as she did not like the neighbourhood in which she found herself. While she was walking in this way down Swandam Lane, she suddenly heard an ejaculation or cry, and was struck cold to see her husband looking down at her and, as it seemed to her, beckoning to her from a second-floor window. The window was open, and she distinctly saw his face, which she describes as being terribly agitated. He waved his hands frantically to her, and then vanished from the window so suddenly that it seemed to her that he had been plucked back by some irresistible force from behind. One singular point which struck her quick feminine eye was that although he wore some dark coat, such as he had started to town in, he had on neither collar nor necktie.
