Her father stroked her hair to still her frenzy, just as he had often done in the stress of some childish tantrum; for Yvonne had never been a demure little saint, but owned in full measure the defects of a frank and impulsive temperament.

"Don't let us give way to hysteria," he said, smiling wanly. "Of course it was my fault. I cracked up first; but I sha'n't offend again. Perhaps, as you say, we may take a more level-headed view of our difficulties in cold daylight. But, to prepare you, so to speak, I must warn you that your mother's chief enemy is that churl Raymond."

"Raymond!" Again was Yvonne almost choked with apprehension. How could her father suspect the devilish scheme the secretary had hatched? Had Lorry probed the depths of the man's evil mind? Her brain swam; but she compelled her faculties to remain alert.

"Yes—Raymond," her father was saying. "I have no absolute proof; but I am convinced that he overheard your mother's frantic words of self reproach when the Hirondelle was coming up the river. The very agent he is employing in Paris, ostensibly in aid of your quest for poor Madeleine, is really engaged in a search into the early records of our lives, your mother's and mine. The inquiry is a simple thing. If Raymond has not secured the necessary evidence already, it is only a matter of hours before it is in his hands. Then, unless a miracle happens, he can dictate his own terms. Worst of all, your mother will be in his power as long as she lives, and an unscrupulous scoundrel, such as I believe Raymond to be, could cause untold mischief after her death."

Yvonne rose to her feet, and straightened her lithe, slim body. With a determined gesture she brushed away a mist from before her eyes. "I want to ask a few questions," she said. "You will be quite open and candid with me, I know, because it is necessary that we should meet the trials of the next few days with the clearest knowledge of each other's aims. Do you think it possible to make any arrangement with Raymond that would be binding?"

"The blackmailer's appetite only grows by feeding. Pay him a very large sum today, and he will demand four or five times the amount within a month or a year. There is no finality. The wolf may eat to repletion; but it will continue to slay in mere lust of killing.

"Is there no way of defeating him?"

"Lorry, as I hinted, hit on a notion. I have no means of knowing exactly what legal steps Carmac and Stella took to make their marriage valid. Carmac might have been advised to establish, or secure, American citizenship. Moreover, French law may adapt itself readily to American standards. Those are points for lawyers; but I want you to go into the matter thoroughly with your mother, and ascertain whether or not there exists any sort of legal barrier that may serve to keep this jackal from devouring her. That is one reason why I have opened my heart to you tonight."

Yvonne had Mrs. Carmac's trick of wrinkling her brows when in deep thought. Many a time had her father chaffed her on the habit, and pretended to wait in breathless suspense till the oracle announced its weighty decision. But the creasing of the smooth forehead passed unnoticed now. They were no longer light-hearted playmates, but a man and a woman pondering one of life's most harrowing problems.

"Raymond can get nothing at all unless he acts through Rupert Fosdyke," she said collectedly. "Why shouldn't an arrangement be made with him—Fosdyke, I mean? It's all a question of this wretched money. Why shouldn't Mother give it to him and his sisters? Surely they would leave her sufficient to live on?"
