"Japanese raiders!" he said. "Can you run?"

"You bet," said Colin, growing excited; "I'm a crack runner."

"Get back to the agent's house as fast as you know how an' wake him up. He'll know what to do."

"What are you after, Hank?" asked the boy, tightening his belt.

"Whatever comes along," was the terse reply.
