"I needn't tell you fellows," he said gravely, "that this place is a little unlike any other in Europe. You may think you're safe enough, but all the same I wouldn't trust a living soul. By-the-by, I saw Felicia as I came in. You don't want her to break down, do you?"

"Good heavens, no!" her brother exclaimed.

"Break down?" David repeated. "Don't suggest such a thing!"

"It struck me that she was rather nervy," Hunterleys told them. "One of you ought to look after her for an hour or two to-morrow."

"I can't spare a moment," her brother sighed.

"I'll take her out," Briston declared eagerly. "There's nothing for me to do to-morrow till Sidney gets back."

"Well, between you, keep an eye on her," Hunterleys advised. "And, Sidney, I don't want to make a coward of you, and you and I both know that if there's danger ahead it's our job to face it, but have a care up at the Villa Mimosa. I don't fancy the law of this Principality would see you out of any trouble if they got an idea that you were an English Secret Service man."

Roche laughed shortly.

"Exactly my own idea," he admitted. "However, we've got to see it through. I sha'n't consider I've done my work unless I hear something of what Grex and the others have to say to Douaille the next time they meet."

Hunterleys found Felicia waiting for him outside. He shook his head reproachfully.
