It was quite dark when the Minister's agent arrived at the Lodge. M. Cognard met him outside the small garden gate. As soon as he caught sight of the slender, grey-clad figure he ran to meet it as fast as his portliness would allow.

"Nothing!" he said breathlessly.

"How do you mean—nothing?" retorted the secret agent.

"Just what I say," replied the commissaire. "We have searched this tumbledown barrack through and through. The women are there—in charge of my men. They did not protest; they did not hinder us in any way. But I tell you," added M. Cognard, as he mopped his streaming forehead, "there's not a cat or a mouse concealed in that place. We have searched every hole and corner."

"Bah!" said the Man in Grey with a frown. "Some secret hiding-place has escaped you!"

"Ask your own trusted men," retorted the commissaire. "They have worked with ours."

"Have you questioned the women?"

"Yes! They adhere to Mademoiselle's story in every point."

"Do they know that I—a member of His Majesty's secret police force—saw Jacques de Romaine enter this house on Tuesday night, and that I swear he did not leave it the whole of that night; whilst my own men are equally ready to swear that he has not left it since?"

"They know that."

"And what is their answer?"

"That we must demand an explanation from the man who was lurking round here in the dark when Jacques de Romaine had priceless jewels in his possession," replied the chief commissary.

The stern features of the Man in Grey relaxed into a smile.

"The rogues are cleverer than I thought," he said simply.

"Rogues?" growled M. Cognard. "I for one do not believe that they are rogues. If Jacques de Romaine entered this house on Tuesday night and has not left it since, where is he now? Answer me that, Monsieur Fernand!"

"Do you think I have murdered him?" retorted the secret agent calmly.

Then he went into the house.

He found Mme. la Comtesse de Romaine entrenched within that barrier of lofty incredulity which she had set up the moment that she heard of the grave suspicion which rested upon her son.

"A Comte de Romaine, Monsieur," she said in her thin, cracked voice in answer to every query put to her by the Man in Grey, "who is also Seigneur de Mazaire and a peer of France, does not steal the jewels of a dancer. If, as that wench asserts, my son had her trinkets that night about his person, then obviously it is for you who were lurking around my house like a thief in the night to give an account of what became of him."

"Your son entered this house last Tuesday night, Madame," answered Fernand firmly, "and has not been out of it since."

"Then I pray you find him, Sir," was Madame de Romaine's rejoinder.

Mademoiselle Mariette's attitude was equally uncompromising. She bore every question and cross-question unflinchingly. But when the secret agent finally left her in peace to initiate a thorough search inside that house which so bafflingly refused to give up its secret, she turned to the chief commissary of police.

"Who is that anonymous creature," she queried with passionate indignation, "who heaps insults and tortures upon my dear mother and me? Why is he not being questioned? Whose is the hidden hand that shields him when retribution should be marking him for its own?"

Whose indeed? The commissary of police was at his wits' end. Even the Man in Grey—resolute, systematic and untiring—failed to discover anything suspicious in the Lodge. It had often been said of him that no secret hiding-place, no secret panel or lurking-hole could escape his eagle eye, and yet, to-day, after three hours' persistent search, he was forced to confess he had been baffled.

Either his men had relaxed their vigilance at some time since that fateful Tuesday night, and had allowed the rogue to escape, or the devil had indeed spirited the young Comte de Romaine up the chimney.

Public opinion at once went dead against the authorities. Mademoiselle de Romaine had taken good care that the story of the man lurking round the Lodge on the night her brother disappeared should be known far and wide. That that man happened to be a mysterious and anonymous member of His Majesty's secret police did not in any way allay the popular feeling. The worthy citizens of St. Lô loudly demanded to know why he was not brought to justice. The préfet, the commissary, the procureur, were all bombarded with correspondence. Indignation meetings were held in every parish of the neighbourhood. Indeed, so tense had the situation become that the chief departmental and municipal officials were tendering their resignations wholesale, for their position, which already was well-nigh intolerable, threatened to become literally dangerous. Sooner or later the public would have to be told that the Man in Grey, on whom so grave a suspicion now rested, had mysteriously vanished, no one knew whither, and that no one dared to interfere with his movements, on pain of having to deal with M. le Duc d'Otrante, His Majesty's Minister of Police, himself.
