"Come on now," Bennett scoffed, "you're talking like a man of ninety. Why, you won't need geriatrics for at least another month."

They both laughed. Bennett was a shy-looking, slender astrophysicist who spoke softly, never seemed to exert himself, and yet commanded the unabashed admiration of every member of the center.

"All right," Lee said. "You didn't call me to discuss my failing years. What's on your mind?"

"Oh, I just thought it's about time you got to work. You've been loafing around for a week now. We can't afford to feed you free forever, you know."

"No, I guess you can't," Lee agreed, smiling.

Bennett leaned back in his chair and studied Lee for a long moment. "I won't ask you why you wanted to come back. But I was delighted when I saw the paperwork with your name on it. Want to know why?"

"Now I am curious."

"I want to leave Titan. I've been heading this operation for too many years, now. I want out. And I really can't leave until I have a top-notch man to run this little show. You're my replacement."

"As director?"

"Yes."
