"Completing a unified theory of life. Why a crystal grows but isn't alive, why an organism that dies isn't like a crystal. What is the process we call life? What is its relationship to the space-time continuum—"

He said it so casually that Walker was caught off his guard completely. "Are you serious, Millet?" he said.

"Certainly. I expect to publish in about two years."

"Is this an independent effort?"

"Not entirely. Others have contributed. Some pioneers long dead, some among the living." His eyes twinkled. "You see, important things beside the development of weapons of destruction do continue in the scientific world. Did you think that was the end of everything for me, ten years ago?" He shook his head in mock gravity. "It was just the beginning. I wanted out, you see."

"You wanted out?" Walker leaned forward, unwilling to believe what he had heard. "Are you trying to tell me that you arranged your discharge?"

Millet shrugged. "Why, of course. Nobody ever has bothered to ask me about that up to now, but I certainly did arrange it. It wasn't hard, you know. All I had to do was set up some sort of relationship with a so-called security risk, and I was on my way out."

"Why ... that's damned near treason."

"Don't be silly. I had other important things to do. In order to do them—to continue work on the unified life theory—it was necessary for me to contact scientists with whom professional relationships were made illegal by security regulations. The choice was simple; besides, I didn't enjoy the idea of spending my life developing ways of destroying the very thing I wanted most to understand."

"This is fantastic, Millet, utterly fantastic."
