The House on the Borderland by William Hope Hodgson

It was now about three a.m., and, presently, the eastern sky began to pale with the coming of dawn. Gradually, the day came, and, by its light, I scanned the gardens, earnestly; but nowhere could I see any signs of the brutes. I leant over, and glanced down to the foot of the wall, to see whether the body of the Thing I had shot the night before was still there. It was gone. I supposed that others of the monsters had removed it during the night.

Then, I went down on to the roof, and crossed over to the gap from which the coping stone had fallen. Reaching it, I looked over. Yes, there was the stone, as I had seen it last; but there was no appearance of anything beneath it; nor could I see the creatures I had killed, after its fall. Evidently, they also had been taken away. I turned, and went down to my study. There, I sat down, wearily. I was thoroughly tired. It was quite light now; though the sun's rays were not, as yet, perceptibly hot. A clock chimed the hour of four.
