that, I doubt if anything would have come of my visit, for he was plainly nervous and ill at ease and very repentant of ever having said anything. But after my compliment to the house we got on better. "It's on my mind," he said; "I shan't be easy till someone else knows." We were in the front room where a good fire was burning--in my honor, I guessed, for the apartment had not the air of being much used. On the table were some photographs. Barnes showed them to me. They were enlargements from those he had taken of poor Radcliffe's last ascent. "They've been shown all over the world," he said. "Millions of people have seen them." "Well?" I said. "But there's one no one has seen--no one except me." He produced another print and gave it to me. I glanced at it. It seemed much like the others, having been apparently one of the last of the series, taken when the aeroplane was at a great height. The only thing in which it differed from the others was that it seemed a trifle blurred."A poor one," I said; "it's misty." "Look at the mist," he said. I did so. Slowly, very slowly, I began to see that that misty appearance had a shape, a form. Even as I looked I saw the features of a human countenance--and yet not human either, so spectral was it, so unreal and strange. I felt the blood run cold in my veins and the hair bristle on the scalp of my head, for I recognised beyond all doubt that this face on the photograph was the same as that Radcliffe had sketched. The resemblance was absolute, no one who had seen the one could mistake the other. "You see it?" Barnes muttered, and his face was almost as pale as mine. "There's a woman," I stammered, "a woman floating in the air by his side. Her arms are held out to him." "Yes," Barnes said. "Who was she?" The print slipped from my hands and fluttered to the ground. Barnes picked it up and put it in the fire. Was it fancy or, as it flared up, and burnt and was consumed, did I really hear a faint laugh floating downwards from the upper air? "I destroyed the negative," Barnes said, "and I told my boss something had gone wrong with it. No one has seen that photograph but you and me, and now no one ever will." VIII THE TERROR BY NIGHT Maynard disincumbered himself from his fishing-creel, stabbed the butt of his rod into the turf, and settled down in the heather to fill a pipe. All round him stretched the undulating moor, purple in the late summer sunlight. To the southward, low down, a faint haze told where the sea lay. The stream at
