“But I’ll warn you. It could be quite dangerous. Even afterward, if they found it out.” She stopped suddenly, frowning a little. “No. Wait. Since you’ve brought up the question, I’ll be perfectly frank with you. There is one aspect of it that probably isn’t quite legal. That is taking a boat into the waters of a foreign country and landing two people secretly. But there’d be no chance of your getting caught, and it doesn’t sound like a particularly reprehensible crime—”

“Depends on what they were being landed for,” I said.

“Simply,” she said, her eyes somber, “so they could live in peace. And go on living.”

I nodded, thinking about it. I had a hunch she was telling it to me straight. She and her husband were running from Tweed Jacket and God knew how many more for some reason, but somehow I couldn’t connect her with anything criminal. Of course, I didn’t know anything about him at all, but I was beginning to like her very much. I tried to warn myself. It hadn’t been twenty minutes since I’d gone off halfcocked in the other direction. Maybe there was just something about her that precluded objective appraisal, at least as far as I was concerned.

“What is the deal, specifically?” I asked.

She took another drag on the cigarette, and crushed it out very slowly in the ash tray. She looked at me. “Just this,” she said. “That you buy and outfit a seaworthy boat large enough to accommodate three people but which can be handled by one seaman with the help of two landlubbers. We’ll furnish the money, of course, but the whole thing is to be done under your name or an assumed one, and we have no connection with it, for obvious reasons, until the very hour we go aboard. Secretly, and without being followed. That isn’t going to be easy, either. Sail us to a place off the coast of Yucatan and recover something from a private plane which crashed and sank—”

“Wait,” I said. “In how much water? Do you know?”

“Just roughly,” she replied. “About sixty feet, I think.”

I nodded. “That’s easy. The depth, I mean. But finding the plane is something else. You could spend years looking for it, and still never locate it. Planes break up fast, especially in exposed positions and shallow water.”

“I believe we can find it,” she said.
