"Not me," Lee said, shaking his head. "I couldn't."

"Why not?"

"Why? Hell, Kim, you saw them carry me out of here five years ago. How do you know the same thing won't happen again? How do I know it?"

A trace of a smile flickered across Bennett's face. "Look, the fact that you returned to Titan—to this center and to that infernal machine out there—well, that's proof enough to me that you've licked whatever it was that caused your breakdown."

"Maybe you're satisfied," Lee countered, "but how about the rest of the staff? How will they feel about having a reconditioned neurotic heading the show?"

Bennett's smile broke into an open grin. "Self-pity is a terrible thing. Do you know what those kids think of you? You're Dr. Sidney Lee, the foremost xeno-anthropologist of the human race. You're the man who deciphered the Martian Script, who uncovered the ruins on Tau Ceti, who did the definitive studies on the cave man cultures on Sirius and Vega. Your troubles here on Titan are just a six-month incident in the middle of a dazzling career. Haven't you noticed the deference with which they've been treating you? You're a big man on this campus."

"I don't know...."

"It won't be a lifetime job," Bennett coaxed. "In a couple of years some of the young squirts around here will have acquired enough poise and self-control to run the show. Then you can go on to something else."

Lee got up from his chair and paced slowly to the bookshelf that lined one wall of the office. "Why don't you stay on for another year or so, and then turn it over to one of the youngsters?"

Bennett wordlessly extended his arms over the desk. His hands were trembling, almost imperceptibly, but trembling.
