“But the rest,” said the Marquis de Kersaint, staring down before him at his locked hands, “were not, in 1792, merely amusing themselves in exile, whatever they may have been doing in 1790. . . . Even though I had not been by her side, if I had been where I ought to have been long before, in the army of the Princes or with Condé, do you think that de Brencourt would say . . . those things? Or that they would be like death to me, if he did? . . . You see you cannot answer that, Pierre!”

“Mon frère,” said M. Chassin quietly, “that delay has been expiated. The question for the moment is, whether M. le Comte suspects your identity.”

M. de Kersaint moved a little. “Do you think he possibly can? I never remember seeing him before in my life, until he was assigned to me last December in Jersey as my lieutenant.”

“And if he had ever chanced to see you before the Revolution,” went on the priest musingly, “this bitter resentment he seems to have would have shown itself ere now. No, he could have had no grounds for suspicion of any kind before last night and the business of Mirabel. It was evidently only the mention of that name that roused him. If he begins to have . . . ideas . . . my advice to you, Gaston, is to tell him who you are. He knows, as most people do, about the part you played at Rivoli, not to speak of what you are doing now, so he would not continue——”

“Never!” broke in the Marquis, making a violent gesture of negation. “I desire never to hear that old name of mine again in this life! And I forbid you once more to tell anyone in the world—anyone—whatever you might think would be gained by it! Is it a promise?”

“You have had my promise once for all, Gaston.”

“I will never see you again if you break it!” said his foster-brother with vehemence.

“Have I kept it so ill these seven years, then, that you think a threat is necessary?” asked the priest gently.

“Oh, my dear Pierre, forgive me!” cried the other instantly, and he held out his hand. “When a man starts threatening the best friend he ever had, to whom he owes not only his life but his sanity, it looks rather as if that sanity was leaving him!”

“I do not see much signs of that,” said the priest, with a smile, as he took the proffered hand. “And last night’s business was horrible. I have always thought,” he went on reflectively, “that M. le Comte was an embittered man.”
