"Beats hunting flying stingarees," Rick agreed. "Pass another crab, please."

Not until the table had been cleared by the waiter, who simply removed the utensils and tray, then wrapped up all the shells in the brown paper and carried it off, did the conversation return to the mystery.

Rick hadn't told Steve of last night's meeting with the white-haired man or of the thinly veiled warning. He described them now in detail.

"Odd," Steve said. "This familiar face needs identifying. No normal person worries about anyone asking casual questions. That's a sure mark of insecurity. In other words, the man is afraid. People who are afraid often have something to hide. Do you have any reason to think he may be tied up with the flying stingarees or saucers?"

"None at all," Rick answered.

"Do you know where Calvert's Favor is?" Scotty asked. "The location wasn't given in your books. There was quite a lot about the plantation house."

"No, never heard of the place. But we'll find out when we pass through Cambridge. I know a man there who knows everything about this area." Steve held out his hand. "Let's see your notebook."

Scotty handed it over. The young agent leafed through it rapidly. "That's some list. If I had any doubt that people were seeing things, it's gone now. How are you going to arrange the data?"

"In tables, and on a map," Rick explained.

"Fine. We can do it tonight. Want anything else?"
