Tales of the Unexpected #224925

I was surprised to hear a queer sort of laugh, and saw Davidson standing unsteadily in the middle of the room, with a dazzled look on his face. My first impression was that he was drunk. He did not notice me. He was clawing out at something invisible a yard in front of his face. He put out his hand, slowly, rather hesitatingly, and then clutched nothing. 'what's come to it?' he said. He held up his hands to his face, fingers spread out. 'great Scott!' he said. The thing happened three or four years ago, when every one swore by that personage. Then he began raising his feet clumsily, as though he had expected to find them glued to the floor.
