"Virtue is its own reward; and there may be others," Schuyler said as he deducted a sum equal to 5 per cent. from Mary's winnings and pushed it across the table.

But even this was not the end of his interference. When Madeleine rose and Mary sprang up obediently, he proposed that they, the three men, should see the ladies home. This plan was carried out; and when Mary had been left at the door of the Hôtel de Paris, they insisted on taking Madame d'Ambre at once down the hill to her lodgings in the Condamine. The penance was made only a little lighter to the victim by a lift in Schuyler's automobile. She was far from grateful to its owner, and made no answer except a twist of the shoulders to his last words: "Remember not to change your mind. It isn't safe in this climate."

When they had dropped Hannaford at his hotel, also in the Condamine, Carleton lost no time in satisfying his curiosity. "I never saw you take so much trouble, Jim, over a woman. Is it a case of love at first sight, old man?"

"Bosh!" said Schuyler, "Don't you know me better? That girl puzzles me. There's something very odd about her. I'm conceited enough to think I can generally size people up pretty well at first sight, but she beats me. I can't make her out. And besides——"

"Besides—what?"

"I know I never saw her before, yet her face seems familiar. I associate her with—it's idiotic—but with the person I care for most in the world. Heaven knows why. I don't."

"Do I know who that person is?" Carleton ventured, unable to resist the temptation.

"No, you don't know," the older man returned, rather gruffly. "And I'm pretty sure you never will, because the less I talk or think about that person the better for me. That part of the story has nothing to do with the case. There's only this queer impression of mine. And I had a weird feeling as if it were my bounden duty to see that this little girl wasn't victimized by an unscrupulous woman. So I did what I could."

"I should think you did!" exclaimed the other. "I couldn't have done as much. Poor Madame d'Ambre."

"Her real name's probably the French for Smith, without a 'de' in it, unless it's to spell devil. If she's a widow, she's a grassy one. Her game is to be found crying on the Casino terrace by moonlight, preparatory to drinking poison, because she's tired of life and its temptations. If it's a young lieutenant just off his ship for a flutter at Monte, or some other lamb of that fleeciness, he's soon shorn. There's quite a good living in it, I understand. She always contrives to make the youngsters believe her an innocent angel, whom they must try to save."
