Jeff nodded, realization striking. What would be more natural to a group of people teetering from day to day on the brink of death? The need for excitement, for activity, would be overpowering in a dismal prison-place like this. And with the huge sums of money yet unearned to bet with--Jeff shuddered. Cut-throat games, yes, but could they really explain this strange tension he sensed? Or had something happened, something to change the atmosphere, to pervade every nook and cranny of the room with an air of explosive tension? Jeff started moving toward the Nasty Frenchman. The little man was gulping coffee in the corner. He sucked on a long, black cigar and appeared to be in deep conversation with a bald-headed giant who leaned against the wall. Jeff spotted Blackie again. She was across the room on her knees. She faced a little buck-toothed man, as she swiftly rolled the three colored dice. Her eyes followed them, quick and unnaturally bright. Jeff shook his head. Panmumjon was a high-speed, high-tension game--a game for the steel-nerved. Its famous dead-locks had often led to murder, as the pots rose higher and higher. The girl seemed to be winning. She rolled the dice with trance-like regularity, and the little buck-toothed man's face darkened as his money pile dwindled. Across the room a corner crap game was moving swiftly, with staggering sums of money passing from hand to hand; the card games, though slower, left the mark of their tension on the players' faces. Jeff still stared, until he had seen every face in the room. Paul Conroe's face was not one of them. No, he had not expected that. But what had happened? It was maddening to stand there, to feel the tension in the room, sense that it was growing until it seemed to pound at his temples. No one else seemed to notice it. Was he the only one aware of the change in the air, in the sounds, even in the color of the light against the walls? Something was impelling him, urging him to run, to get away, to leave the room now while he could. Yet when he tried to analyze the creeping, poisonous fear, tried to pin it down, it wriggled away into the fringes of his mind, and mocked him. Finally, he reached the corner of the room. His ear caught the Nasty Frenchman's nasal voice, and he froze as he stared at the little man. "I tell you, Harpo, I heard it with my own ears. You never saw Schiml so excited. And then Shaggy Parsons was saying that the whole unit was being split up--that's the A unit. I saw him when I was going through this afternoon. He was all excited, too." "But why split it up?" The huge bald-headed man called Harpo growled, his heavy lips twisting in disgust. "I don't trust Shaggy Parsons for nothin', and I think you hear what you want to hear. What's the point to it? Schiml's coming along fine in the work he's using us in--"
