"... and so you see, John, by following this trail, I've arrived at a theory that has to do with the basic nature of the universe—of all reality. Yet things don't behave as they would if my theory were operating."

John Henderson frowned into space, disturbed. Visibly disturbed. Martin watched him with a twinkle in his eyes.

"You must have gone off the track on it somewhere, Martin," John said suddenly, as though trying more to convince himself than his listener.

Martin shook his head with slow positiveness. "You followed every step. We spent four hours on it." He took pity on his friend. "Don't let it bother you. I regard it as just an intellectual curiosity. I've included it in my next book on that basis."

"Yes, Father."
