"Quite right!—quite right!" said M. Fantin querulously. "Now, Monsieur Fernand, will you come?"

"One moment, Monsieur le Commissaire," said the secret agent, and suddenly his whole manner changed to one of commanding authority. "There will be plenty of time for excuses presently. For the nonce you will order your captain to make a thorough search of this château and of the grounds around. You will question every one of the domestics; and remember that I shall be about somewhere—probably unseen—but present, nevertheless, to see that the investigation is minute and thorough. Sébastien will remain in the meanwhile in the custody of these two men here, until I have need of him again."

"By Heaven!" protested the Commissaire roughly.

"By Heaven!" retorted the Man in Grey loudly, "you'll obey my orders now, Monsieur le Commissaire, or I shall send you straight to Monsieur the Minister to report upon your own misconduct!"

M. Fantin, at the threat and at the manner in which it was uttered, became as white as a sheet. But he obeyed—at once and without another word. Sébastien's rugged face had shown no sign of emotion as, at a curt word from the secret agent, the two men of the police closed up on either side and marched him into an adjoining room.

The commissary had taken the threat of the Minister's all-powerful agent very much to heart. His men searched the château through and through, just as if it had been the stronghold of some irreconcilable rebel. The secret agent himself appeared and disappeared, while the search was going on, like some grey will-o'-the-wisp—now in one room, now in another, now a passage, now half-way upstairs, just where least expected. The search took over three hours. During that time Monseigneur himself sat in his room in front of the fire, the very picture of silent and offended dignity. He listened—motionless and dignified—to the commissary's profuse apologies, only now and then accepting the ministrations of the lackey who remained with him throughout, bathing his forehead with vinegar, or mixing a fresh glass of orange-flower water. Of the grey-clad figure which flittered unceremoniously in and out of his private apartments, he took no more notice than if he were a fly.

When presently the police actually invaded his own bedroom, Monseigneur's attitude remained one of unapproachable reserve. Even when the agent passed his hands over the wainscoting and presently found the button that worked the secret spring, Monseigneur showed neither interest nor emotion. The hiding-place itself was found to be empty; the Man in Grey walked into it and out again, in a matter-of-fact, impassive manner, as if he were performing a mechanical and useless job. Neither here nor inside the house, nor in the grounds, nor in any other hiding-place was anyone or anything found to impeach Monseigneur's well-known loyalty.

The unfortunate commissary was covered with confusion. He would gladly have strangled the meddlesome official who had placed him in such an awkward position, or even have relieved his feelings by hurling anathema upon him. But the secret agent appeared indifferent both to the wrath of M. Fantin and to the silent disapprobation of the Bishop. When he was satisfied that the search was done, and well done, he took his leave, but not before.

Monseigneur did not vouchsafe him even a look. But he was quite affable with M. le Commissaire, when the latter finally was allowed to depart.

"Have you any further orders, Monsieur Fernand?" queried M. Fantin with bitter sarcasm, when he had bowed his way out of the presence of the outraged prelate.
