"Just as glad you haven't, then," remarked Tony cheerfully. Carefully, he brought the boat alongside the Sleuth and Frank and Joe jumped over the side into their own craft.
Paul Blum was resigned. He submitted to having his wrists bound with a piece of stout rope that the boys found on the stern of the boat, and then he sat down philosophically.
"I'll get away yet," he told them. "If I can't escape from that jail myself, my friends will see that I get out."
"How will we get back?" asked Frank, turning to Tony.
Paul Blum laughed.
"That's a problem for you," he said. "The gas tank's empty. What are you going to do about it?"
Tony calmly handed over the can of gasoline from his own boat.
"This should help," he remarked. "I always keep some spare gas on hand."
Paul Blum, beaten, had no more to say. The Hardy boys poured the reserve supply of gasoline into the tank, and in a few minutes the engine was pounding away.
Then, side by side, the two motorboats turned about and put back for Bayport.
