Night Without End by Alistair MacLean

young pilot had been dead for several hours. I knelt there for a long time, just looking down at him, and when I finally rose to my feet I did so like an old man, a defeated old man, and I felt as cold, almost, as the dead man lying there. Everyone was wide awake now, everyone staring at me, the eyes of nearly all of them reflecting the superstitious horror which the presence of sudden and unexpected death brings to those who are unaccustomed to it. It was Johnny Zagero who broke the silence. 
         
         "He's dead, isn't he, Dr Mason?" His low voice sounded a little husky. "That head injury-" His voice trailed off. 
         
         "Cerebral haemorrhage," I said quietly, "as far as I can tell." 
         
         I lied to him. There was no shadow of doubt in my mind as to the cause of death. Murder. The young boy had been ruthlessly, cold-bloodedly murdered: lying there unconscious, gravely injured and with his hands strapped helplessly to his sides, he had been smothered as easily, as surely, as one might smother a very little child. 
         
         We buried him out on the ice-cap, not fifty yards from the place where he had died. Bringing his stiffened body out of the hatch was a grisly job, but we managed it and laid him on the snow while we sawed out a shallow grave for him in the light of one of our torches. It was impossible to dig it out: that frozen ringing surface turned shovel blades as would a bar of iron: even at eighteen inches, the impacted ntvt of snow and ice defied the serrated spearpoints of our special snow saws. But it was deep enough and within a few hours the eternal ice-drift would have smoothed its blanket across the grave, and we would never be able to find it again. The Reverend Joseph Smallwood murmured some sort of burial service over the grave but his teeth chattered so violently in the cold and his voice was so low and indistinct and hurried that I could hardly catch a word of it. I thought wryly that heavenly forgiveness for this indecent haste was unlikely to be withheld: by all odds it must have been by far the coldest funeral service that Mr Smallwood had ever conducted. 
         
         Back in the cabin, breakfast was a sketchy and silent affair. Even in the steadily rising warmth, the melancholy gloom was an almost palpable blanket under the dripping ceiling. Hardly anybody said anything, hardly anybody ate anything. Margaret Ross ate nothing, and when she finally set down her coffee-cup, the contents had scarcely been touched. 
         
         You're overdoing it, my dear, I thought viciously, you're carrying the grief-stricken act just a little too far: a little longer, and even the others will start wondering - and they have no suspicions at all, you damned inhuman little murderess. 
         
         For I had no suspicions either - only certainty. There was no doubt in my mind at all but that she had smothered the young pilot. She' was only slightly built - but then it would have required only slight strength. Lashed to the cot as he had been, he wouldn't even have been able to drum his heels as he had died. I could feel my flesh crawl at the very thought. 
         
         She had killed him, just as she had broken the radio and doped the passengers. He had been killed, obviously, to keep him from talking - about what, I couldn't even begin to guess, any more than I could guess the reason for the destruction of the radio, except that she clearly did not want the news of the crash broadcast to the outer world. But why in the world destroy the radio in the first place, surely she must have known how essential it was for survival? But then, after all, how was she even to have guessed that: she might well have thought that we had big fast tractors that could have whipped them down to the coast in a matter of a couple of days. For that matter, she might have thought she was a great deal nearer the coast than we really were -it was
