“I picked up the revolver and saw, almost without emotion, that it was my own. Manderson had taken it from my room, I suppose, while I was getting out the car. At the same moment I remembered that it was by Manderson’s suggestion that I had had it engraved with my initials, to distinguish it from a precisely similar weapon which he had of his own.
“I bent over the body and satisfied myself that there was no life left in it. I must tell you here that I did not notice, then or afterwards, the scratches and marks on the wrists, which were taken as evidence of a struggle with an assailant. But I have no doubt that Manderson deliberately injured himself in this way before firing the shot; it was a part of his plan.
“Though I never perceived that detail, however, it was evident enough as I looked at the body that Manderson had not forgotten, in his last act on earth, to tie me tighter by putting out of court the question of suicide. He had clearly been at pains to hold the pistol at arm’s length, and there was not a trace of smoke or of burning on the face. The wound was absolutely clean, and was already ceasing to bleed outwardly. I rose and paced the green, reckoning up the points in the crushing case against me.
“I was the last to be seen with Manderson. I had persuaded him—so he had lied to his wife and, as I afterwards knew, to the butler—to go with me for the drive from which he never returned. My pistol had killed him. It was true that by discovering his plot I had saved myself from heaping up further incriminating facts—flight, concealment, the possession of the treasure. But what need of them, after all? As I stood, what hope was there? What could I do?”
Marlowe came to the table and leaned forward with his hands upon it. “I want,” he said very earnestly, “to try to make you understand what was in my mind when I decided to do what I did. I hope you won’t be bored, because I must do it. You may both have thought I acted like a fool. But after all the police never suspected me. I walked that green for a quarter of an hour, I suppose, thinking the thing out like a game of chess. I had to think ahead and think coolly; for my safety depended on upsetting the plans of one of the longest-headed men who ever lived. And remember that, for all I knew, there were details of the scheme still hidden from me, waiting to crush me.
“Two plain courses presented themselves at once. Either of them, I thought, would certainly prove fatal. I could, in the first place, do the completely straightforward thing: take back the dead man, tell my story, hand over the notes and diamonds, and trust to the saving power of truth and innocence. I could have laughed as I thought of it. I saw myself bringing home the corpse and giving an account of myself, boggling with sheer shame over the absurdity of my wholly unsupported tale, as I brought a charge of mad hatred and fiendish treachery against a man who had never, as far as I knew, had a word to say against me. At every turn the cunning of Manderson had forestalled me. His careful concealment of such a hatred was a characteristic feature of the stratagem; only a man of his iron self-restraint could have done it. You can see for yourselves how every fact in my statement would appear, in the shadow of Manderson’s death, a clumsy lie. I tried to imagine myself telling such a story to the counsel for my defence. I could see the face with which he would listen to it; I could read in the lines of it his thought, that to put forward such an impudent farrago would mean merely the disappearance of any chance there might be of a commutation of the capital sentence.
“True, I had not fled. I had brought back the body; I had handed over the property. But how did that help me? It would only suggest that I had yielded to a sudden funk after killing my man, and had no nerve left to clutch at the fruits of the crime; it would suggest, perhaps, that I had not set out to kill but only to threaten, and that when I found that I had done murder the heart went out of me. Turn it which way I would, I could see no hope of escape by this plan of action.
“The second of the obvious things that I might do was to take the hint offered by the situation, and to fly at once. That too must prove fatal. There was the body. I had no time to hide it in such a way that it would not be found at the first systematic search. But whatever I should do with the body, Manderson’s not returning to the house would cause uneasiness in two or three hours at most. Martin would suspect an accident to the car, and would telephone to the police. At daybreak the roads would be scoured and enquiries telegraphed in every direction. The police would act on the possibility of there being foul play. They would spread their nets with energy in
