There was someone there all right, but I didn't have to worry about his reactions. Not any more. He'd none left. He was lying face down on the bunk with that huddled shapeless look that belongs only to the dead. I made a quick traverse of the cabin with the pencil beam. The dead man was alone. As in the radio cabin, there was no sign of a struggle.

I didn't even have to touch him to ascertain the cause of death. The amount of blood that had seeped from that half-inch incision in his spine wouldn't have filled a teaspoon. I wouldn't have expected to find more; when the spinal column has been neatly severed the heart doesn't go on pumping long enough to matter a damn. There would have been a little more internal bleeding, but not much.

The curtains were drawn. I quartered every foot of the deck, bulkheads and furniture with my flash. I don't know what I expected to find: what I found was nothing. I went out, closed the door behind me and searched the radio cabin with the same results. There was nothing more for me here, I had found all I wanted to find, all I had never wanted to find. And I never once looked at the faces of the two dead men. I didn't have to, they were faces I knew as well as the face that looked back at me every morning out of my shaving mirror. Seven days previously they had dined with me and our chief in our favourite pub in London and they had been as cheerful and relaxed as men in their profession can ever be, their normal still watchfulness overlaid by the momentary savouring of the lighter side of life they knew could never really be for them. And I had no doubt they had gone on being as still and watchful as ever, but they hadn't been watchful enough and now they were only still.
