Punctually at eight o’clock Graham Vane had taken his seat at a corner table at the remote end of the cafe Jean Jacques, called for his cup of coffee and his evening journal, and awaited the arrival of M. Lebeau. His patience was not tasked long. In a few minutes the Frenchman entered, paused at the comptoir, as was his habit, to address a polite salutation to the well-dressed lady who there presided, nodded as usual to Armand Monnier, then glanced round, recognized Graham with a smile, and approached his table with the quiet grace of movement by which he was distinguished.

Seating himself opposite to Graham, and speaking in a voice too low to be heard by others, and in French, he then said,

“In thinking over your communication this morning, it strikes me as probable, perhaps as certain, that this Louise Duval or her children, if she have any, must be entitled to some moneys bequeathed to her by a relation or friend in England. What say you to that assumption, Monsieur Lamb?”

“You are a sharp fellow,” answered Graham. “Just what I say to myself. Why else should I be instructed to go to such expense in finding her out? Most likely, if one can’t trace her, or her children born before the date named, any such moneys will go to some one else; and that some one else, whoever he be, has commissioned my employer to find out. But I don’t imagine any sum due to her or her heirs can be much, or that the matter is very important; for, if so, the thing would not be carelessly left in the hands of one of the small fry like myself, and clapped in along with a lot of other business as an off-hand job.”

“Will you tell me who employed you?”

“No, I don’t feel authorized to do that at present; and I don’t see the necessity of it. It seems to me, on consideration, a matter for the police to ferret out; only, as I asked before, how should I get at the police?”

“That is not difficult. It is just possible that I might help you better than any lawyer or any detective.”

“Why, did you ever know this Louise Duval?”

“Excuse me, Monsieur Lamb; you refuse me your full confidence; allow me to imitate your reserve.”

“Oho!” said Graham; “shut up as close as you like; it is nothing to me. Only observe, there is this difference between us, that I am employed by another. He does not authorize me to name him, and if I did commit that indiscretion, I might lose my bread and cheese. Whereas you have nobody’s secret to guard but your own, in saying whether or not you ever knew a Madame or Mademoiselle Duval; and if you have some reason for not getting me the information I am instructed to obtain, that is also a reason for not troubling you further. And after all, old boy” (with a familiar slap on Lebeau’s stately shoulder), “after all, it is I who would employ you; you don’t employ me. And if you find out the lady, it is you who would get the L100., not I.”

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.”

“Bon! I will wait. Here comes M. Georges. I leave you to dominos and him. Good-night.”

Late that night M. Lebeau was seated alone in a chamber connected with the cabinet in which he received visitors. A ledger was open before him, which he scanned with careful eyes, no longer screened by spectacles. The survey seemed to satisfy him. He murmured, “It suffices, the time has come,” closed the book, returned it to his bureau, which he locked up, and then wrote in cipher the letter here reduced into English:—
