“By letting the girl go, he’s exposed us. Griffin now knows that we are working against him. And he is, according to old Erich, the only man we have to fear.”

“Except that man Farquhar, partner with Sir George Gavin, the newspaper owner.”

“Ah! I forgot him. But surely he doesn’t count?”

“Yes, he does,” protested Jannaway. “He’s in love with the girl. Hence we must see that he turns his back upon her, or there may be further trouble. I foresee pretty awkward complications in that direction.”

“Very well, my dear boy, all that I leave to you,” answered Sir Felix, with a heavy, thoughtful look.

“But it does not lessen our danger. If we’re not careful we’ll lose the thing altogether,” Jannaway pointed out. “I’ve been a full fortnight making careful investigations. The Doctor called on Griffin the day before yesterday, and what’s more, the girl has written to Charlie, asking him to meet her.”

“How have you found that out?”

Jim Jannaway smiled.

“No matter,” he laughed. “Except that Laura, the parlour-maid at Pembridge, is a friend of mine. I took her to the Tivoli last Thursday. Told her I was a lawyer’s clerk.”

“By Jove, Jim,” exclaimed the Baronet, “you’re always ingenious when you’ve set your mind on worming out a secret.”
