Corentin rose, stepped back a pace or two, and looked at Marie.

“You have grown rich in a very short time,” he said, in a tone of ill-disguised bitterness.

“Montauran,” she continued, “will make you a better offer still for his ransom. Now, then, prove to me that you have the means of guaranteeing him from all danger and—”

“Can’t you send him away the moment he arrives?” cried Corentin, suddenly. “Hulot does not know he is coming, and—” He stopped as if he had said too much. “But how absurd that you should ask me how to play a trick,” he said, with an easy laugh. “Now listen, Marie, I do feel certain of your loyalty. Promise me a compensation for all I lose in furthering your wishes, and I will make that old fool of a commandant so unsuspicious that the marquis will be as safe at Fougeres as at Saint-James.”

“Yes, I promise it,” said the girl, with a sort of solemnity.

“No, not in that way,” he said, “swear it by your mother.”

Mademoiselle de Verneuil shuddered; raising a trembling hand she made the oath required by the man whose tone to her had changed so suddenly.

“You can command me,” he said; “don’t deceive me again, and you shall have reason to bless me to-night.”

“I will trust you, Corentin,” cried Mademoiselle de Verneuil, much moved. She bowed her head gently towards him and smiled with a kindness not unmixed with surprise, as she saw an expression of melancholy tenderness on his face.

“What an enchanting creature!” thought Corentin, as he left the house. “Shall I ever get her as a means to fortune and a source of delight? To fling herself at my feet! Oh, yes, the marquis shall die! If I can’t get that woman in any other way than by dragging her through the mud, I’ll sink her in it. At any rate,” he thought, as he reached the square unconscious of his steps, “she no longer distrusts me. Three hundred thousand francs down! she thinks me grasping! Either the offer was a trick or she is already married to him.”
