hter of Auguste Duval, artiste en dessin, to
come forward. Monsieur objects to that."

"I object to it extremely; as I have told you, this is a strictly
confidential inquiry; and an advertisement which in all likelihood would
be practically useless (it proved to be so in a former inquiry)
would not be resorted to unless all else failed, and even then with
reluctance."

"Quite so. Accordingly, Monsieur delegates to me, who have been
recommended to him as the best person he can employ in that department
of our police which is not connected with crime or political
surveillance, a task the most difficult. I have, through strictly
private investigations, to discover the address and prove the identity
of a lady bearing a name among the most common in France, and of whom
nothing has been heard for fifteen years, and then at so migratory an
endroit as Aix-la-Chapelle. You will not or cannot inform me if since
that time the lady has changed her name by marriage."

"I have no reason to think that she has; and there are reasons against

"Permit me to observe that the more details of information Monsieur can
give me, the easier my task of research will be."

"I have given you all the details I can, and, aware of the difficulty of

your advice in our first interview, of asking some Parisian friend of
mine, with a large acquaintance in the miscellaneous societies of your
capital, to inform me of any ladies of that name whom he might chance
to encounter; and he, like you, has lighted upon one or two, who alas!
resemble the right one in name and nothing more."

"You will do wisely to keep him on the watch as well as myself. If it
were but a murderess or a political incendiary, then you might trust
exclusively to the enlightenment of our corps, but this seems an affair
of sentiment, Monsieur. Sentiment is not in our way. Seek the trace of
that in the haunts of pleasure."

M. Renard, having thus poetically delivered himself of that
philosophical dogma, rose to depart.

Graham slipped into his hand a bank-note of sufficient value to justify
the profound bow he received in return.

When M. Renard had gone, Graham heaved another impatient sigh, and said
to himself, "No, it is not possible,--at least not yet."

Then, compressing his lips as a man who forces himself to something he
dislikes, he dipped his pen into t
