"The old Comtesse only goes to church, and Mademoiselle Mariette goes sometimes to market."

"So much the better for you. Your men will have an easy time."

"But——"

"I pray you do not argue, my good Monsieur Moulin. Mademoiselle Mariette may be out shopping at this very moment."

And when the accredited agent said "I pray you," non-compliance was out of the question.

Later in the day the préfet talked the matter over with M. Cognard, chief commissary of police, who had had similar orders in the matter of the Romaines. The two cronies had had their tempers sorely ruffled—by the dictatorial ways of the secret agent, whom they hated with all the venom that indolent natures direct against an energetic one.

"The little busybody," vowed M. Moulin, "sees conspirators in every harmless citizen and interferes in matters which of a truth have nothing whatever to do with him."

Then in the very midst of the complacency of these two worthies came the memorable day which, in their opinion, was the most turbulent one they had ever known during their long and otiose careers.

It was the day following the arrival of the secret agent at St. Lô, and he had come to the commissariat that morning for the sole purpose—so M. Cognard averred—of making matters uncomfortable for everybody, when Mademoiselle de Romaine was announced. Mademoiselle had sent in word that she desired to speak with M. le Commissaire immediately, and a minute or two later she entered, looking like a pale ghost in a worn grey gown, and with a cape round her shoulders which was far too thin to keep out the cold on this winter's morning.
