CHAPTER IV
Visitors by Night
Rick and Scotty stood on the pier and watched their erstwhile shadow row slowly toward another pier some distance away.
"We probably should have tied him up and called the police," Rick remarked.
"It wouldn't have gotten us anything," Scotty disagreed. "He could always claim he didn't see us in the water. After all, it wouldn't be the first time divers had been run over by motorboats."
"It's too late now, anyway. Let's dress, then go to the hotel and tell Zircon and Tony about this."
As they dressed in the small cabin of the Water Witch, Rick spoke aloud the question that had been bothering him. "What did he have to gain by running us down? That's what puzzles me. It was a stupid thing to try, because he didn't really have much chance of getting both of us, or even one, once he failed to catch us by surprise."
"He wasn't very well prepared for murder, either," Scotty added. "No weapons except a switch knife."
Rick nodded agreement. "He was desperate," he concluded. "Suddenly he had to take a chance on getting us. He must have known it wasn't much of a chance. Either he lost his head, or he wasn't very bright. What could have made him try?"
Scotty had no answer, nor could Rick even hazard a reasonable guess.
