"Don't comrade me and don't but me either. I know where you came from."

"Where?" asked Dugan.

"You know," said the tall man. But Dugan didn't.

Dugan had planned, in the shower room, that he would take Hundeshausen to his room, keep Hundeshausen awake long enough to pump all available information out of him, then gag him and tie him up and — equipped with sightseeing papers comprising Hundeshausen's identity card and passes — go out for a night's tour of Atomsk. Then he had thought of simply putting Hundeshausen under the bed, out of sight, and going to sleep in Hundeshausen's bed himself, for an hour or two. He could count on himself to awaken, and could have made the trip with greater physical strength and intellectual alertness. Finally, when Hundeshausen gave him the four names, he had wanted only to check the names back with documents or with further talk from Hundeshausen, and then to escape. But all these plans had gone awry. The Cossack was making plans. And he looked as if he could.

The tall man said, "Left."

They entered room 146.

The tall man said to Dugan, "What is your section number?"

"Section number?"

"You know your section number," said the Russian crossly. "Don't you understand Russian? Deine Verwendung-skammernummer," he added in German. "Your Utilization Chamber Number."

Utilization Chamber — that's what I'm supposed to be in, thought Dugan. A show of obstinacy would not be out of place. He kept silent.
