Marlowe turned upon him with a glowing face. “And I think you will understand me, Mr. Trent,” he said in a voice that shook a little, “when I say that if such a possibility had occurred to me then, I would have taken any risk rather than make my escape by that way. … Oh well!” he went on more coolly, “I suppose that to anyone who didn’t know her, the idea of her being privy to her husband’s murder might not seem so indescribably fatuous. Forgive the expression.” He looked attentively at the burning end of his cigarette, studiously unconscious of the red flag that flew in Trent’s eyes for an instant at his words and the tone of them.
That emotion, however, was conquered at once. “Your remark is perfectly just,” Trent said with answering coolness. “I can quite believe, too, that at the time you didn’t think of the possibility I mentioned. But surely, apart from that, it would have been safer to do as I said; go by the window of an unoccupied room.”
“Do you think so?” said Marlowe. “All I can say is, I hadn’t the nerve to do it. I tell you, when I entered Manderson’s room I shut the door of it on more than half my terrors. I had the problem confined before me in a closed space, with only one danger in it, and that a known danger: the danger of Mrs. Manderson. The thing was almost done; I had only to wait until she was certainly asleep after her few moments of waking up, for which, as I told you, I was prepared as a possibility. Barring accidents, the way was clear. But now suppose that I, carrying Manderson’s clothes and shoes, had opened that door again and gone in my shirtsleeves and socks to enter one of the empty rooms. The moonlight was flooding the corridor through the end window. Even if my face was concealed, nobody could mistake my standing figure for Manderson’s. Martin might be going about the house in his silent way. Bunner might come out of his bedroom. One of the servants who were supposed to be in bed might come round the corner from the other passage—I had found Célestine prowling about quite as late as it was then. None of these things was very likely; but they were all too likely for me. They were uncertainties. Shut off from the household in Manderson’s room I knew exactly what I had to face. As I lay in my clothes in Manderson’s bed and listened for the almost inaudible breathing through the open door, I felt far more ease of mind, terrible as my anxiety was, than I had felt since I saw the dead body on the turf. I even congratulated myself that I had had the chance, through Mrs. Manderson’s speaking to me, of tightening one of the screws in my scheme by repeating the statement about my having been sent to Southampton.”
Marlowe looked at Trent, who nodded as who should say that his point was met.
“As for Southampton,” pursued Marlowe, “you know what I did when I got there, I have no doubt. I had decided to take Manderson’s story about the mysterious Harris and act it out on my own lines. It was a carefully prepared lie, better than anything I could improvise. I even went so far as to get through a trunk call to the hotel at Southampton from the library before starting, and ask if Harris was there. As I expected, he wasn’t.”
“Was that why you telephoned?” Trent enquired quickly.
“The reason for telephoning was to get myself into an attitude in which Martin couldn’t see my face or anything but the jacket and hat, yet which was a natural and familiar attitude. But while I was about it, it was obviously better to make a genuine call. If I had simply pretended to be telephoning, the people at the exchange could have told at once that there hadn’t been a call from White Gables that night.”
“One of the first things I did was to make that enquiry,” said Trent. “That telephone call, and the wire you sent from Southampton to the dead man to say Harris hadn’t turned up, and you were returning—I particularly appreciated both those.”
A constrained smile lighted Marlowe’s face for a moment. “I don’t know that there’s anything more to tell. I returned to Marlstone, and faced your friend the detective with such nerve as I had left. The worst was when I heard you had been put on the case—no, that wasn’t the worst. The worst was when I saw you walk out of the shrubbery the next day, coming away from the shed where I had laid the body. For one ghastly moment I thought you were going to give me in charge on the spot. Now I’ve told you everything, you don’t look so terrible.”
He closed his eyes, and there was a short silence. Then Trent got suddenly to his feet.
“Cross-examination?” enquired Marlowe, looking at him gravely.
“Not at all,” said Trent, stretching his long limbs. “Only stiffness of the legs. I don’t want to ask any questions. I believe what you have told us. I don’t believe it simply because I always liked your face, or because it saves awkwardness, which are the most usual reasons for believing a person, but because my vanity will
