his head then, and forced his eyes open. There was a dim, feeble glow from somewhere overhead and to his right, but it was enough to show him a vaulted ceiling a few feet above him. He was lying in some sort of tube which— And then the sudden realization came. He was in a sewer. The shock of it cleared his mind a little, and gave added strength to his muscles. He pushed himself to his hands and knees and began crawling toward the dim light. It wasn't more than eight or ten feet, but it seemed to take an eternity for him to get there. Above him was a grating, partially covered with a soggy-looking sheet of paper. The light evidently came from a glow-plate several yards away. He lay there, exhausted and aching, trying to force his brain into action, trying to decide what to do next. He'd have to lift the grating, of course; that much was obvious. And he'd have to stand up to do that. Did he have the strength? Only one way to find out. Again he pushed himself to his hands and knees, and it seemed easier this time. Then, bracing himself against the curving wall of the sewer, he got to his feet. His knees were weak and wobbly, but they'd hold. They had to hold. The top of the sewer duct was not as far off as it had seemed; he had to stoop to keep from banging his head against the grating. He paused in that position to catch his breath, and then reached up, first with one hand and then with the other, to grasp the grating. Then, with all the strength he could gather, he pushed upwards. The hinged grate moved upwards and banged loudly on the pavement. There remained the problem of climbing out of the hole. The Guesser never knew how he solved it. Somehow, he managed to find himself out of the sewer and lying exhausted on the pavement. He knew that there was some reason why he couldn't just lie there forever, some reason why he had to hide where he couldn't be seen. It was not until that moment that he realized that he was completely naked. He had been stripped of everything, including the chronometer on his wrist. With an effort, he heaved himself to his feet again and began running, stumbling drunkenly, yet managing somehow to keep on his feet. He had to find shelter, find help.
