"Well, it's a reputable, highly competent and conservative group of some of the best scientific brains in the country. But somehow, these two got attached to it. They're not very conservative, although they're competent—especially at getting into trouble."

Kelly gave the boys a comradely grin. "If he talks that way, he must like you."

The boys grinned back. The lieutenant was likable.

"All right. Last I saw of you two, Rick was lying across the legs of the guy who had been tailing me. The next thing I heard, two men we've been keeping an eye on were in the hoosegow, one with a slug in his shoulder. And I also heard some wild tales of jumping out of windows. Now fill in the details."

Rick started from the moment they first noticed that a shadow had picked them up. He told the story in careful and accurate detail, knowing that Steve's trained mind might find significance in things that meant nothing to him. Now and then Scotty elaborated on a point.

When Rick concluded the recital, Steve cupped his chin in one hand and stared at them thoughtfully.

Kelly complimented them. "Sounds as if you took care of things like real professionals, both in the water and in the hotel. And I must say, I wish my people would learn to give reports like that."

The boys thanked him, and Scotty added, "I don't suppose you can tell us anything about what you do?"

"Sure I can. I'm not one of Steve's hush-hush crew. I'm a simple Navy lieutenant."

Rick chuckled. "In other words, you can't tell us."
