"You'll have to postpone that," Hunterleys told him. "I want to borrow the yacht."

"She's yours," Richard assented promptly. "I'll give you a note to the captain."

"Look here, I want you to understand this clearly," Hunterleys went on. "If you lend me the Minnehaha, well, you commit yourself a bit. You see, it's like this. I've one man of my own in Grex's household. He came to me this morning. Monsieur Douaille objects to cross again the threshold of the Villa Mimosa. He fears the English newspapers. There has been a long discussion as to the next meeting-place. Grex suggested a yacht. To that they all agreed. There is a man named Schwann down in Monaco has a yacht for hire. Mr. Grex knows about it and he has sent the man I spoke of into Monaco this afternoon to hire it. They are all going to embark at ten o'clock to-night. They are going to hold their meeting in the cabin."

Lane whistled softly. He was wide awake now.

"Go on," he murmured. "Go on. Say, this is great!"

"I want," Hunterleys explained, "your yacht to take the place of the other. I want it to be off the Villa Mimosa at ten o'clock to-night, your pinnace to be at the landing-stage of the villa to bring Mr. Grex and his friends on board. I want you to haul down your American flag, keep your American sailors out of sight, cover up the Stars and Stripes in your cabin, have only your foreign stewards on show. Schwann's yacht is a costly one. No one will know the difference. You must get up now and show me over the boat. I have to scheme, somehow or other, how we can hide ourselves on it so that I can overhear the end of this plot."

The face of Richard Lane was like the face of an ingenuous boy who sees suddenly a Paradise of sport stretched out before him. His mouth was open, his eyes gleaming.

"Gee, but this is glorious!" he exclaimed. "I'm with you all the way. Why, it's wonderful, man! It's a chapter from the Arabian Nights over again!"

He leapt to his feet and rang the bell furiously. Then he rushed to the telephone.

"Blue serge clothes," he ordered the valet. "Get my bath ready."
