He stooped and took one of madame's hands that lay limply in her lap.
"Good-bye, Thérèse!" His voice broke. He had reached the end of his iron self-control.
She rose and clung to him a moment, unashamed before them. The ashes of that dead romance had been deeply stirred this night, and deep down some lingering embers had been found that glowed brightly now before their final extinction. Yet she made no attempt to detain him. She understood that their son had pointed out the only wise, the only possible course, and was thankful that M. de La Tour d'Azyr accepted it.
"God keep you, Gervais," she murmured. "You will take the safe-conduct, and ... and you will let me know when you are safe?"
He held her face between his hands an instant; then very gently kissed her and put her from him. Standing erect, and outwardly calm again, he looked across at André-Louis who was proffering him a sheet of paper.
"It is the safe-conduct. Take it, monsieur. It is my first and last gift to you, and certainly the last gift I should ever have thought of making you—the gift of life. In a sense it makes us quits. The irony, sir, is not mine, but Fate's. Take it, monsieur, and go in peace."
M. de La Tour d'Azyr took it. His eyes looked hungrily into the lean face confronting him, so sternly set. He thrust the paper into his bosom, and then abruptly, convulsively, held out his hand. His son's eyes asked a question.
"Let there be peace between us, in God's name," said the Marquis thickly.
Pity stirred at last in André-Louis. Some of the sternness left his face. He sighed. "Good-bye, monsieur," he said.
"You are hard," his father told him, speaking wistfully. "But perhaps you are in the right so to be. In other circumstances I should have been proud to have owned you as my son. As it is..." He broke off abruptly, and as abruptly added, "Good-bye."
