Hunterleys nodded thoughtfully.

"Frenhofer," he explained, "my scheme is this. A friend of mine has a yacht in the harbour. I believe that he would lend it to me. Why should we not substitute it for the yacht your master imagines that he is hiring? If so, all difficulties as to placing whom I desire on board and secreting them are over."

"It is a great scheme," Frenhofer assented, "but supposing my master should choose to telephone some small detail to the office of the man Schwann?"

"You must hire the yacht of Schwann, just as you were instructed," Hunterleys pointed out. "You must give orders, though, that it is not to leave the harbour until telephoned for. Then it will be the yacht which I shall borrow which will lie off the Villa Mimosa to-night."

"It is admirable," Frenhofer declared. "The more one thinks of it, the more one appreciates. This yacht of Schwann's—the Christable, he calls it—was fitted out by a millionaire. My master will be surprised at nothing in the way of luxury."

"Tell me again," Hunterleys asked, "at what hour is it to be off the Villa Mimosa?"

"At ten o'clock," Frenhofer replied. "A pinnace is to be at the landing-stage of the villa at that time. Mr. Grex, Monsieur Douaille, Herr Selingman, and Mr. Draconmeyer will come on board."

"Very good! Now go on your errand to the man Schwann. You had better meet me here later in the afternoon—say at four o'clock—and let me know that all is in order. I will bring you some particulars about my friend's boat, so that you will know how to answer any questions your master may put to you."

"It is admirable," Frenhofer repeated enthusiastically. "Monsieur had better, perhaps, precede me."

Hunterleys walked through the streets back to Ciro's Restaurant, filled with a new exhilaration. His eyes were bright, his brain was working all the time. The luncheon-party at the next table were still in the midst of their meal. Mr. Simpson was smoking a meditative cigarette with his coffee. Hunterleys resumed his place and ordered coffee for himself.
