M. Lebeau mechanically brushed, with a light movement of hand, the shoulder which the Englishman had so pleasantly touched, drew himself and chair some inches back, and said slowly,—

"Monsieur Lamb, let us talk as gentleman to gentleman. Put aside the question of money altogether; I must first know why your employer wants to hunt out this poor Louise Duval. It may be to her injury, and I would do her none if you offered thousands where you offer pounds. I forestall the condition of mutual confidence; I own that I have known her,—it is many years ago; and, Monsieur Lamb, though a Frenchman very often injures a woman from love, he is in a worse plight for bread and cheese than I am if he injures her for money."

"Is he thinking of the duchess's jewels?" thought Graham. "Bravo, mon vieux," he said aloud; "but as I don't know what my employer's motive in his commission is, perhaps you can enlighten me. How could his inquiry injure Louise Duval?"

"I cannot say; but you English have the power to divorce your wives. Louise Duval may have married an Englishman, separated from him, and he wants to know where he can find, in order to criminate and divorce her, or it may be to insist on her return to him."

"Bosh! that is not likely."

"Perhaps, then, some English friend she may have known has left her a bequest, which would of course lapse to some one else if she be not living."

"By gad!" cried Graham, "I think you hit the right nail on the head: c'est cela. But what then?"

"Well, if I thought any substantial benefit to Louise Duval might result from the success of your inquiry, I would really see if it were in my power to help you. But I must have time to consider."

"How long?"

"I can't exactly say; perhaps three or four days."
