CHAPTER XVI

The Deadly Spring Gun

The storm blew itself out by noon of the following day, leaving an overcast sky and heavy swells. An inspection with the binoculars showed that all was quiet at the frogmen's house. Their boat was tied to the pier.

"They probably recovered the brass ball during the night," Rick observed, "or perhaps early this morning."

"The question is," Scotty remarked, "did they take the gadget to the octopus cave?"

Tony joined them on the porch in time to hear Scotty's query. "I can shed some light on that. It happens that I woke up at dawn and looked out to see how the weather was behaving. The frogmen were anchored off the eastern reef in the same place. We can assume that they picked up the brass ball and put it back in the cave near the wreck."

Rick rubbed his hand over his short hair in a gesture of bewilderment. "But what's their game? What do they get from the brass ball?"

"I rather imagine Steve Ames would like to know the same thing. If you boys have no objection, I think I'll spend the afternoon at my midden. What are you planning?"
