"We will speak of that later, my friend," observed Lefevre, quietly. "Just at present I propose that we return to Mr. Stapleton's without a moment's delay. Her heart is breaking with anxiety." He took Grace's arm and assisted her to enter the automobile, where Mr. Stapleton had already preceded them with his son. "It is to you, my dear child," he said to Grace, as she sunk weakly back upon the cushioned seat, "that Mrs. Stapleton will owe all her happiness."

It was a cheerful party that broke in upon the banker's wife a short time later. Duvall, under the stimulus of Grace's presence, had completely forgotten his wound; while Grace, who had been but momentarily stunned by the blow which the kidnapper had given her, was radiant with joy at once more feeling her husband's arms about her.

Monsieur Lefevre carried them both off to his house, as soon as the boy had been restored to his mother. The happiness of the banker's reunited family was too great to permit them to be even mildly interested in the affairs of Richard Duvall and his wife, and they, too, wished to be alone. It seemed to them both as though ages had passed since they had seen each other; they could scarcely realize that it had been but a little over two weeks. Richard especially seemed unable to grasp the truth of the situation. He plied Grace with numberless questions, and could scarcely believe that he had actually been within arm's length of her on at least four different occasions during the past week without knowing it.

Monsieur Lefevre advised him to leave the whole matter until the next day. "You should be proud of your wife, Monsieur," he said, gravely. "But for her, I doubt if Monsieur Stapleton would ever have seen his boy again. And that reminds me," he smiled mischievously, "that I have won that little bet. It was Mademoiselle Goncourt, of my office, that recovered the lost child."

"I think the honors are pretty evenly divided, Monsieur," laughed Grace, happily, as she pressed her husband's hand. "Don't forget that if Richard hadn't gotten my message, all my work would have gone for nothing."

"Suppose we call it a draw, then," said the Prefect. "All in the family, as you Americans say. And to show that I am not prejudiced, one way or the other, I suggest that you both, with Mr. and Mrs. Stapleton, dine with me tomorrow evening. There are many points connected with this case which are by no means cleared up, and we should talk them over. Although we have secured the missing child, and three of the kidnappers, we do not yet know how the child was stolen, or whether the nurse, Mary Lanahan, is innocent or guilty of any part in his mysterious disappearance in the Bois de Boulogne. I confess that I have all along considered her guilty, and am inclined to order her arrest at once."

"It will be useless, Monsieur," remarked Duvall, quietly. "She is entirely innocent."

"You mean that she knows nothing of how the boy was spirited away?"

"Nothing!"

"Mon Dieu! Then the thing may forever remain a mystery."
