Fortunately, the street at the moment was deserted. Around one, two, then three corners Hal doubled, and then slowed down.

"Guess we are all right for a few minutes," he gasped.

Uncle John stopped and gasped for breath.

"I'm not as young as I used to be, Hal," he said. "Don't forget that. I can't go a hundred yards in eleven seconds any more."

"Well, you didn't miss it much," said Hal, with a chuckle. "But come on, we must get away from here. If we are caught now, the chances are they will stand us up against a wall and have a shot at us."

"In which event," said Uncle John dryly, "I can still do a hundred yards in ten flat."

Side by side the two walked on.

"The question that now arises," said Uncle John, "is how we are going to get away from here?"

"First," said Hal, "we must go back and see if Chester is still where we left him."

"Like looking for a needle in a haystack," said Uncle John. "This is a pretty good-sized town."
