“Can’t you siphon it out?”

“Not without a tube, and I didn’t bring one.”

“You’ll never in the world make a G-man,” sighed Penny. “Well, at least you can describe the fellow who hired you.”

Bill’s brow puckered. “I didn’t pay much attention,” he admitted. “I’d say the fellow was about thirty-eight, with a little trick moustache.”

“That can’t be the man who originally rented the boat from Sara,” Penny remarked, frowning.

“Say, are you really sure this boat belongs to the Ottmans?” Bill asked. “You know they’re pretty badly tangled with the police. It said in the papers—”

“I know,” interrupted Penny wearily. “Or do I know? I’m so mixed I feel like a perpetual motion machine running backwards.”

“We’ve been watching here all day,” Louise added, her voice quavering. “We’ve had nothing to eat. No wonder our minds are failing.”

“Why don’t you go home?”

“And let a saboteur run off with this boat?” Penny demanded. “We promised to stay here until Sara comes.”
