"But now I cast about desperately for some tale that would seem more plausible than the truth. Could I save my neck by a lie? One after another came into my mind; I need not trouble to remember them now. Each had its own futilities and perils; but every one split upon the fact—or what would be taken for fact—that I had induced Manderson to go out with me, and the fact that he had never returned alive. Notion after notion I swiftly rejected as I paced there by the dead man, and doom seemed to settle down upon me more heavily as the moments passed. Then a strange thought came to me.
"Several times I had repeated to myself half-consciously, as a sort of refrain, the words in which I had heard Manderson tell his wife that I had induced him to go out. 'Marlowe has persuaded me to go for a moonlight run in the car. He is very urgent about it.' All at once it struck me that, without meaning to do so, I was saying this in Manderson's voice.
"As you found out for yourself, Mr. Trent, I have a natural gift of mimicry. I had imitated Manderson's voice many times so successfully as to deceive even Bunner, who had been much more in his company than his own wife. It was, you remember,"—Marlowe turned to Mr. Cupples—"a strong, metallic voice, of great carrying power, so unusual as to make it a very fascinating voice to imitate, and at the same time very easy. I said the words carefully to myself again, like this—" he uttered them, and Mr. Cupples opened his eyes in amazement—"and then I struck my hand upon the low wall beside me. 'Manderson never returned alive?' I said aloud. 'But Manderson shall return alive!'
"In thirty seconds the bare outline of the plan was complete in my mind. I did not wait to think over details. Every instant was precious now; I lifted the body and laid it on the floor of the car, covered with a rug. I took the hat and the revolver. Not one trace remained on the green, I believe, of that night's work. As I drove back to White Gables my design took shape before me with a rapidity and ease that filled me with a wild excitement. I should escape yet! It was all so easy if I kept my pluck. Putting aside the unusual and unlikely, I should not fail. I wanted to shout, to scream! Nearing the house I slackened speed, and carefully reconnoitered the road. Nothing was moving. I turned the car into the open field on the other side of the road, about twenty paces short of the little door at the extreme corner of the grounds. I brought it to rest behind a stack. When, with Manderson's hat on my head and the pistol in my pocket, I had staggered with the body across the moonlit road and through that door, I left much of my apprehension behind me. With swift action and an unbroken nerve, I thought I ought to succeed."
With a long sigh Marlowe threw himself into one of the deep chairs at the fireside, and passed his handkerchief over his damp forehead. Each of his hearers, too, drew a deep breath, but not audibly.
"Everything else you know," he said. He took a cigarette from a box beside him and lighted it. Trent watched the very slight quiver of the hand that held the match, and privately noted that his own at the moment was not so steady.
"The shoes that betrayed me to you," pursued Marlowe after a short silence, "were painful all the time I wore them, but I never dreamed that they had given anywhere. I knew that no footstep of mine must appear by any accident in the soft ground about the hut where I laid the body, or between the hut and the house, so I took the shoes off and crammed my feet into them as soon as I was inside the little door. I left my own shoes, with my own jacket and overcoat, near the body, ready to be resumed later. I made a clear footmark on the soft gravel outside the French window, and several on the drugget round the carpet. The stripping off of the outer clothing of the body and the dressing of it afterwards in the brown suit and shoes, and putting the things into the pockets, was a horrible business; and getting the teeth out of the mouth was worse. The head ... but you don't want to hear about it. I didn't feel it much at the time. I was wriggling my own head out of a noose, you see. I wish I had thought of pulling down the cuffs, and had tied the shoes more neatly. And putting the watch in the wrong pocket was a bad mistake. It had all to be done so hurriedly.
"You were wrong, by the way, about the whisky. After one stiffish drink I had no more; but I filled up a flask that was in the cupboard, and pocketed it. I had a night of peculiar anxiety and effort in front of me, and I didn't know how I should stand it. I had to take some once or twice during the drive. Speaking of that, you give rather a generous allowance of time in your document for doing that run by night. You say that to get to Southampton by half-past six in that car under the conditions, a man must, even if he drove like a demon, have left Marlstone by twelve at latest. I had not got the body dressed in the other suit, with tie and watch-chain and so forth, until nearly ten minutes past; and then I had to get to the car and start it going.... But then I don't suppose any demon would have taken the risks I did in that car at night, without a head-light. It turns me cold to think of it now.
"There's nothing much to say about what I did in the house. I spent the time after Martin had left me in carefully thinking over the remaining steps in my plan, while I unloaded and thoroughly cleaned the revolver, using my handkerchief and a penholder from the desk. I also placed the packets of notes, the note-case and the diamonds in the roll-top desk, which I opened and re-locked with Manderson's key. When I went upstairs it was a trying moment, for though I was safe from the eyes of Martin as he sat in his pantry, there was a faint possibility of somebody being about on the bedroom floor. I had sometimes found the French maid wandering about there when the other servants were in bed. Bunner, I knew, was a deep sleeper. Mrs. Manderson, I had gathered from things I had heard her say, was usually asleep by eleven; I had thought it possible that her gift of sleep had helped her to retain all her beauty and vitality in spite of a marriage which we all knew was an unhappy one. Still, it was uneasy work mounting the stairs and holding myself ready to retreat to the library again at the least sound from above. But nothing happened.
"The first thing I did on reaching the corridor was to enter my room and put the revolver and cartridges back in the case. Then I turned off the light and went quietly into Manderson's room.
