I was perplexed, and seeing it, he laughed.

"Let us make no bones about it," he said, laying down his cigar. "Here's a discarded prince whom no one wants, sailing for no one knows where, with his fortune on board and no one responsible for him. Do you take me now?"

"I'm hanged if I do," I replied testily, for indeed I had no thought of what the man was driving at. But here it came out with a burst.

"Doctor, all this is in our hands. We can do what we will. We're masters of the situation."

I opened my mouth and stared at him. The broad swarthy face loomed like a menace in the uncertain light before us. It was dark; it was inscrutable; a heavy resolution was marked in that thick neck, low brow, and salient chin. We eyed each other in silence.

"It's God's truth I haven't, doctor," he replied earnestly. "I mean what I say. See, the prince carries away a million, and if the prince disappears the million belongs to those who can find it. Now, we don't want any truck with dismounted princes. We're playing for our own hand. I know you take sensible views on these matters. I admit it makes one blink a bit at first, but stick on to the idea, turn it round, and you'll get used to it. It spells a good deal to poor devils like you and me."

"You must be mad," I said angrily, "or——" He interrupted me.

"That's not my line. I'm in dead sober earnest. You hold on to the notion, and you'll come round to it. It's a bit steep at first to the eye. But you hang on to it like a sensible man."

"Good Heavens, man," said I, "are you plotting murder?"
