The duty list lay on his desk, as it had every morning for years. Sebastian MacMaine felt tense and a little irritated with himself, but he felt nothing that could be called a premonition. When he read the first item on the duty list, his irritation became a little stronger. "Interrogate Kerothi general." The interrogation duty had swung round to him again. He didn't want to talk to General Tallis. There was something about the alien that bothered him, and he couldn't
