Saltea

“What I saw was the Count’s head coming out from the window. I did not see the face, but I knew the man by the neck and the movement of his back and arms. In any case I could not mistake the hands which I had had some many opportunities of studying. I was at first interested and somewhat amused, for it is wonderful how small a matter will interest and amuse a man when he is a prisoner. But my very feelings changed to repulsion and terror when I saw the whole man slowly emerge from the window and begin to crawl down the castle wall over the dreadful abyss, face down with his cloak spreading out around him like great wings. At first I could not believe my eyes. I thought it was some trick of the moonlight, some weird effect of shadow, but I kept looking, and it could be no delusion. I saw the fingers and toes grasp the corners of the stones, worn clear of the mortar by the stress of years, and by thus using every projection and inequality move downwards with considerable speed, just as a lizard moves along a wall.”
