"Did the submarine actually put out to sea with you on board?"

She nodded her head, and then very deliberately added, "Yes, I have told you that I was out for two hours. They all knew it—the men and officers of the flotilla. I was horribly frightened, but—but now I am glad indeed that I went. Yes, I am indeed glad!"

"Why are you glad?" he asked roughly—and again a hateful suspicion thrust itself insistently upon him.

"I am glad I went, because it will make what Claire has done to-day seem natural, a—a simple escapade."

There was a moment of terrible silence between them.

"Then do all the officers and men belonging to the flotilla know that my wife is out there—in the Neptune?" Jacques de Wissant asked in a low, still voice.

"No," said Madeleine, and there was now a look of shame, as well as of terror, on her face. "They none of them know—only those who are on board." She hesitated a moment—"That is why I sent the servants away this morning. We—I mean Commander Dupré and I—did not think it necessary that anyone should know."

"Then no one—that is, only a hare-brained young officer and ten men belonging to the town of Falaise—were to be aware of the fact that my wife had accompanied her lover on this life-risking expedition? You and Dupré were indeed tender of her honour—and mine."

"Jacques!" She took her hand off the chair, and faced her brother-in-law proudly. "What infamous thing is this that you are harbouring in your mind? My sister is an honest woman, aye, as honest, as high-minded as was your own mother——"

He stopped her with a violent gesture. "Do not mention Claire and my mother in the same breath!" he cried.
