The three gathered in the living room, and Tony chuckled. "If I associate with you two for much longer, I'll get to be the world's champion dissembler."

"What happened?" Rick demanded.

"Simple and unlucky. The two frogmen surfaced practically under me. My own fault, because I had moved much closer to the boat. I think one of them almost fired a spear at me, but the other stopped him. They invited me to go aboard, and I didn't think it wise to refuse the invitation."

"I imagine not," Rick commented grimly. "Then what?"

"Naturally, they demanded to know what I was doing. I admitted to overpowering curiosity that got the better of my manners. They wanted to know who I was and why I was on the island. I told them the truth, of course, at least partly. I identified all of us. Then I'm afraid I told a slight untruth. I said we had found reference to the Maiden Hand in an old manuscript, and were diving in hopes of finding cannon and other old things which we planned to sell for museum pieces to pay for our vacation. I believe they accepted my story."

"It's a good story," Scotty approved. "Just enough truth to make it ring true."

"They've been watching us," Tony went on. "They asked why the plane had gone, and why it had come back with only the pilot. I told them Professor Zircon had cut himself and gotten a coral infection, and that the doctor at Charlotte Amalie felt that he should stay there for treatment."

"I guess they haven't recognized Scotty and me as the two who stopped Steve's tail."

"Seems not," Tony agreed. "Well, I admitted that I was still curious about their activities, since night diving is not common. So they told me a story."

The boys waited breathlessly.
