In the afternoon, as it was not one of my days to be in Harley Street, I looked up an old friend who lives close to Hyde Park, and found that he was just off to Brighton on some business or other. I had tea with him, and saw him off by the 5:35 from Victoria. On issuing from the barrier it occurred to me to purchase an evening paper, and I thoughtlessly turned my steps to the bookstall. The usual crowds were rushing to catch suburban trains home, and on moving away I found myself involved in a contrary stream of travellers coming up out of the Underground, or bolting from all sides for the 5:45 to Battersea Park and Wandsworth Common. I disengaged myself after some buffeting and went home in a taxi; and it was not till I was safely seated there that I discovered somebody's gold-rimmed pince-nez involved in the astrachan collar of my overcoat. The time from 6:15 to seven I spent concocting something to look like a bogus report for Sir Reuben.
At seven I went through to the hospital, and found the workhouse van just delivering my subject at the side door. I had him taken straight up to the theatre, and told the attendant, William Watts, that I intended to work there that night. I told him I would prepare the body myself — the injection of a preservative would have been a most regrettable complication. I sent him about his business, and then went home and had dinner. I told my man that I should be working in the hospital that evening, and that he could go to bed at 10:30 as usual, as I could not tell whether I should be late or not. He is used to my erratic ways. I only keep two servants in the Battersea house — the man-servant and his wife, who cooks for me. The rougher domestic work is done by a charwoman, who sleeps out. The servants' bedroom is at the top of the house, overlooking Prince of Wales Road.
As soon as I had dined I established myself in the hall with some papers. My man had cleared dinner by a quarter past eight, and I told him to give me the siphon and tantalus; and sent him downstairs. Levy rang the bell at twenty minutes past nine, and I opened the door to him myself. My man appeared at the other end of the hall, but I called to him that it was all right, and he went away. Levy wore an overcoat with evening dress and carried an umbrella. «Why, how wet you are!» I said. «How did you come?» «By 'bus,» he said, «and the fool of a conductor forgot to put me down at the end of the road. It's pouring cats and dogs and pitch-dark — I couldn't see where I was.» I was glad he hadn't taken a taxi, but I had rather reckoned on his not doing so. «Your little economies will be the death of you one of these days,» I said. I was right there, but I hadn't reckoned on their being the death of me as well. I say again, I could not have foreseen it.
I sat him down by the fire, and gave him a whisky. He was in high spirits about some deal in Argentines he was bringing off the next day. We talked money for about a quarter of an hour and then he said:
«Well, how about this Peruvian mare's-nest of yours?»
«It's no mare's-nest,» I said; «come and have a look at it.»
I took him upstairs into the library, and switched on the centre light and the reading lamp on the writing table. I gave him a chair at the table with his back to the fire, and fetched the papers I had been faking, out of the safe. He took them, and began to read them, poking over them in his short-sighted way, while I mended the fire. As soon as I saw his head in a favourable position I struck him heavily with the poker, just over the fourth cervical. It was delicate work calculating the exact force necessary to kill him without breaking the skin, but my professional experience was useful to me. He gave one loud gasp, and tumbled forward on to the table quite noiselessly. I put the poker back, and examined him. His neck was broken, and he was quite dead. I carried him into my bedroom and undressed him. It was about ten minutes to ten when I had finished. I put him away under my bed, which had been turned down for the night, and cleared up the papers in the library. Then I went downstairs, took Levy's umbrella, and let myself out at the hall door, shouting «Good-night» loudly enough to be heard in the basement if the servants should be listening. I walked briskly away down the street, went in by the hospital side door, and returned to the house noiselessly by way of the private passage. It would have been awkward if anybody had seen me then, but I leaned over the back stairs and heard the cook and her husband still talking in the kitchen. I slipped back into the hall, replaced the umbrella in the stand, cleared up my papers there, went up into the library and rang the bell. When the man appeared I told him to lock up everything except the private door to the hospital. I waited in the library until he had done so, and about 10:30 I heard both servants go up to bed. I waited a quarter of an hour longer and then went through to the dissecting-room. I wheeled one of the stretcher-tables through the passage to the house door, and then went to fetch Levy. It was a nuisance having to get him downstairs, but I had not liked to make away with him in any of the ground-floor rooms, in case my servant should take a fancy to poke his head in during the few minutes that I was out of the house, or while locking up. Besides, that was a flea-bite to what I should have to do later. I put Levy on the table, wheeled him across to the hospital and substituted him for my interesting pauper. I was sorry to have to abandon the idea of getting a look at the latter's brain, but I could not afford to incur suspicion. It was still rather early, so I knocked down a few minutes getting Levy ready for dissection. Then I put my pauper on the table and trundled him over to the house. It was now five past eleven, and I thought I might conclude that the servants were in bed. I carried the body into my bedroom. He was rather heavy, but less so than Levy, and my Alpine experience had taught me how to handle bodies. It is as much a matter of knack as of strength, and I am, in any case, a powerful man for my height. I put the body into the bed — not that I expected anyone to look in during my absence, but if they should they might just as well see me apparently asleep in bed. I drew the clothes a little over his head, stripped, and put on Levy's clothes, which were fortunately a little big for me everywhere, not forgetting to take his spectacles, watch and other oddments. At a little before half past eleven I was in the road looking for a cab. People were just beginning to come home from the theatre, and I easily secured one at the corner of Prince of Wales Road. I told the man to drive me to Hyde Park Corner. There I got out, tipped him well, and asked him to pick me up again at the same place in an hour's time. He assented with an understanding grin, and I walked on up Park Lane. I had my own clothes with me in a suitcase, and carried my own overcoat and Levy's umbrella. When I got to No. 9 there were lights in some of the top windows. I was very nearly too early, owing to the old man's having sent the servants to the theatre. I waited about for a few minutes, and heard it strike the quarter past midnight. The lights were extinguished shortly after, and I let myself in with Levy's key.
It had been my original intention, when I thought over this plan of murder, to let Levy disappear from the study or the dining-room, leaving only a heap of clothes on the hearth-rug. The accident of my having been able to secure Lady Levy's absence from London, however, made possible a solution more misleading, though less pleasantly fantastic. I turned on the hall light, hung up Levy's wet overcoat and placed his umbrella in the stand. I walked up noisily and heavily to the bedroom and turned off the light by the duplicate switch on the landing. I knew the house well enough, of course. There was no chance of my running into the man-servant. Old Levy was a simple old man, who liked doing things for himself. He gave his valet little work, and never required any attendance at night. In the bedroom I took off Levy's gloves and put on a surgical pair, so as to leave no telltale finger-prints. As I wished to convey the impression that Levy had gone to bed in the usual way, I simply went to bed. The surest and simplest method of making a thing appear to have been done is to do it. A bed that has been rumpled about with one's hands, for instance, never looks like a bed that has been slept in. I dared not use Levy's brush, of course, as my hair is not of his colour, but I did everything else. I supposed that a thoughtful old man like Levy would put his boots handy for his valet, and I ought to have deduced that he would fold up his clothes. That was a mistake, but not an important one. Remembering that well-thought-out little work of Mr. Bentley's, I had examined Levy's mouth for false teeth, but he had none. I did not forget, however, to wet his toothbrush.
