"He'll be waiting for you when you come out. And you'll have to come out after a while.”

"We rest and take it easy," said Gary, "while he tears up the ground outside and wears himself to a frazzle. And we do some thinking.”

"It's a lousy way to fight," the voice insisted.

"Look," said Gary. "Who's doing the fighting here?

You or us.”
