M. Lecoq affectionately pressed his friend's hand.

"I have only known you a few hours," said he, "and yet I am as devoted to you as I would be to an old friend. All that is humanly possible for me to do to serve you, I shall certainly do."

"But where shall I see you? They expect me to-day at Orcival."

"Very well; to-morrow morning at nine, at my rooms. No—Rue Montmartre."

"A thousand thanks; I shall be there."

When they had reached the Belle Image they separated.

"Monsieur Lecoq?" said he to an old woman who was engaged in getting breakfast for three large cats which were mewing around her. The woman scanned him with a surprised and suspicious air. M. Plantat, when he was dressed up, had much more the appearance of a fine old gentleman than of a country attorney; and though the detective received many visits from all sorts of people, it was rarely that the denizens of the Faubourg Saint Germaine rung his bell.
