"What followed gave me, slight as it was, my first impression of something odd being afoot. As soon as I mentioned the word 'expenses' his hand went mechanically to his left hip-pocket, where he always kept a little case containing notes to the value of about a hundred pounds in our money. This was such a rooted habit in him that I was astonished to see him check the movement suddenly. Then, to my greater amazement, he swore viciously under his breath. I had never heard him do this before; but Bunner had told me that of late he had often shown irritation in this way when they were alone. 'Has he mislaid his note-case?' was the question that flashed through my mind. But it seemed to me that it could not affect his plan at all, and I will tell you why. The week before, when I had gone up to London to carry out various commissions, including the booking of a berth for Mr. George Harris, I had drawn a thousand pounds for Manderson from his bankers; and all, at his request, in notes of small amounts. I did not know what this unusually large sum in cash was for; but I did know that the packets of notes were in his locked desk in the library, or had been earlier in the day, when I had seen him fingering them as he sat at the desk. "But instead of turning to the desk, Manderson stood looking at me. There was fury in his face, and it was a strange sight to see him gradually master it until his eyes grew cold again. 'Wait in the car,' he said slowly. 'I will get some money.' We both went out, and as I was getting into my overcoat in the hall I saw him enter the drawing-room, which, you remember, was on the other side of the entrance hall. "I stepped out onto the lawn before the house and smoked a cigarette, pacing up and down. I was asking myself again and again where that thousand pounds was; whether it was in the drawing-room; and if so, why. Presently, as I passed one of the drawing-room windows, I noticed Mrs. Manderson's shadow on the thin silk curtain. She was standing at her escritoire. The window was open, and as I passed I heard her say: 'I have not quite thirty pounds here. Will that be enough?' I did not hear the answer, but next moment Manderson's shadow was mingled with hers, and I heard the chink of money. Then, as he stood by the window, and as I was moving away, these words of his came to my ears--and these at least I can repeat exactly, for astonishment stamped them on my memory--'I'm going out now. Marlowe has persuaded me to go for a moonlight run in the car. He is very urgent about it. He says it will help me to sleep, and I guess he is right.'
