Gross was staring at him oddly. Kramer shifted uneasily. “Then who is supposed to do it?” Gross said. “I can have my organization prepare examinations of various kinds, to determine fitness, that kind of thing—” “Listen, Phil,” Dolores said suddenly. “What?” She turned toward him. “I have an idea. Do you remember that professor we had in college. Michael Thomas?” Kramer nodded. “I wonder if he’s still alive.” Dolores frowned. “If he is he must be awfully old.” “Why, Dolores?” Gross asked. “Perhaps an old person who didn’t have much time left, but whose mind was still clear and sharp—” “Professor Thomas.” Kramer rubbed his jaw. “He certainly was a wise old duck. But could he still be alive? He must have been seventy, then.” “We could find that out,” Gross said. “I could make a routine check.” “What do you think?” Dolores said. “If any human mind could outwit those creatures—” “I don’t like the idea,” Kramer said. In his mind an image had appeared, the image of an old man sitting behind a desk, his bright gentle eyes moving about the classroom. The old man leaning forward, a thin hand raised— “Keep him out of this,” Kramer said. “What’s wrong?” Gross looked at him curiously. “It’s because I suggested it,” Dolores said. “No.” Kramer shook his head. “It’s not that. I didn’t expect anything like this, somebody I knew, a man I studied under. I remember him very clearly. He was a very distinct personality.” “Good,” Gross said. “He sounds fine.” “We can’t do it. We’re asking his death!” “This is war,” Gross said, “and war doesn’t wait on the needs of the individual. You said that yourself. Surely he’ll volunteer; we can keep it on that basis.”
