"By the way," he said, "did you know that your brother is returning to Earth tomorrow?"

INTERLUDE

Is this our young man, Dr. Farnsworth?" asked the man in uniform.

"Yes, it is. Colonel Mannheim, I'd like you to meet Mr. Bartholomew Stanton."

"How are you, Mr. Stanton?"

"Fine, Colonel. A little nervous."

The colonel chuckled softly. "I can't say that I blame you. It's not an easy decision to make." He looked at Dr. Farnsworth. "Has Dr. Yoritomo any more information for us?"

Farnsworth shook his head. "No. He admits that his idea is nothing more than a wild hunch. He seems to think that five years of observing the Nipe won't be too much time at all. We may have to act before then."

"I hope not. It would be a terrible waste," said Mannheim. "Mr. Stanton, I know that Dr. Farnsworth has outlined the entire plan to you, and I'm sure you're aware that many things can change in five years. We may have to play by ear long before that. Do you understand what we are doing, and why it must be done this way?"
