"That's not all," Rick added. He told of their conversation at the Narrows and of the talk with Orvil Harris that morning. "So there's something fishy around here besides crabs and rockfish. We thought you might know," he concluded.

Steve shook his head with obvious admiration. "Leave it to the Spindrift twins! If there's a mystery afoot, you'll unearth it. Nope, lads. Never heard of your flying stingarees, or flying saucers, either. But that's not surprising. I'm down here mostly on weekends, sometimes with a friend or two, and the only local folks we see are at the store or gas station. Usually I'm in too much of a rush for small talk. I don't get the local papers, and when I listen to the radio or watch TV, it's either a Washington or Baltimore station. So I'm not in touch with local events."

"Anyway," Rick said, "stingarees don't fly."

Steve had been in the Virgin Islands, too, and had been involved in the adventure of The Wailing Octopus. "You found out that the octopus didn't wail," he reminded them, "but for a while it looked as though you'd found a new species. Maybe this is the same thing. What makes the stingaree fly?"

"It would be fun to find out," Scotty admitted.

"You'll have time to make a start, and I won't be in the way with plans for fishing or crabbing. I'm sorry, boys, but I'll be in and out of Washington for a few days. Got a hot case working that I can't leave for long."

The boys protested. "You deserve some vacation," Rick said hotly.

Steve held up his hand. "Whoa! I'm getting a vacation. This case should be settled in three or four days, and I'll be with you. Meanwhile, you move in here. You can drive me to the airport at Cambridge and pick me up when I come back. That will leave you a car, and you can use the motorboat for exploring or for fishing. If you feel like skin diving, you can try for rock or hardheads off the northern tip of Taylors Island, right at the mouth of the river. Did you bring gear?"

"The whole set," Rick replied. "Lungs, compressors, guns, and even suits."

"You won't need suits. The bay is shallow and warm. At night you can relax right here. Plenty of books, TV, radio, or a chessboard. If it gets cool, there's wood for the fireplace."
