"At first my wife and I had every reason to congratulate ourselves on having secured such a competent, refined and charming woman to preside over the education of our children. Marie Vaillant was gay, pretty and full of spirits. The children loved her, especially Ernest, who set his entire childish affections upon his young and attractive governess. During the summer lessons were done out of doors, and long expeditions were undertaken in the woods, whence Ernest and Adèle would return, hot, tired and happy. They had played at being explorers in virgin forests, so they told their mother.

"It was only when the evenings waxed longer," continued the sous-préfet, in a tone of growing embarrassment, now that he was nearing the climax of his story, "that Mademoiselle Vaillant suddenly changed. She developed a curious proclivity for promiscuous coquetry."

"Coquetry?" broke in the secret agent with a smile.

"Yes! Marie began to flirt—shamelessly, openly, with every man she came across, visitors, shop-keepers, friends and gardeners. She exercised an almost weird fascination over them; one and all would anticipate her slightest wish; in fact, the men about the house and grounds of Les Colombiers appeared to be more her servants than ours. Moreover, she made an absolute fool of our butler, Lavernay—a middle-aged man who ought to have known better. He has not only pursued Mademoiselle Vaillant with his attentions but also with his jealousy, until Madame Leblanc felt that her whole household was becoming the laughing-stock of the neighbourhood."

"And have you or Madame Leblanc done anything in the matter?" asked the Man in Grey, while M. le Sous-Préfet paused to draw breath.

"Oh, yes! Madame spoke to the girl and I trounced Lavernay. Marie was humble and apologetic and Lavernay very contrite. Both promised to be discreet and sensible in future. At the same time I confess that I was not at all reassured. Within a fortnight we heard through the gossip of a busybody that Marie Vaillant was in the habit of stealing out of the house in the evenings, at an hour when respectable people should be in bed, and after five minutes' start she was usually followed on these peregrinations by the butler. There was no doubt about the whole thing: even our sergeant of police had witnessed these clandestine meetings and had reported the matter to the local commissary.

"There was nothing for it now but to dismiss the flirtatious governess as quickly as possible. I may say that Madame Leblanc, who had been genuinely fond of the girl, acquitted herself of the task with remarkable tact and gentleness. Marie Vaillant, indeed, belied her name when she received the news of her dismissal. She begged and implored my wife's forgiveness, swore by all she could think of that she had only erred from ignorance; she had no thought of doing wrong; she was innocent of anything but the merest flirtation. Fond of breathing the midnight air which was so balmy and sweet in the woods, she had lately got into the habit of strolling out when she could not sleep and sitting for an hour or so dreaming among the trees. She admitted that once or twice she had been followed by Lavernay, had been very angry with him, and had seriously rebuked him; but it should never, never happen again—she vowed and swore it should not—if only Madame would forgive her and not send her away from Les Colombiers which was like a home to her, and from Ernest and Adèle whom she loved as if they were her brother and sister.

"But Madame Leblanc was inexorable. Perhaps she felt that quite so much ignorance of the ways of the world and the decorum prescribed to every well educated woman was not altogether credible; perhaps she thought that the lady did protest too much. Certain it is that though she went back on her original pronouncement that the girl must leave the house within twenty-four hours, she refused to consider the question of allowing her to remain permanently.

"It was finally agreed that Marie Vaillant should leave Les Colombiers at the end of the month: but that at the slightest transgression or repetition of the old offence she would be dismissed with contumely and turned out of the house at an hour's notice.

"This happened exactly a fortnight ago," went on M. Leblanc, who was at last drawing to the end of what had proved a lengthy soliloquy; "and I may tell you that since then Mademoiselle Vaillant has grown the model of all the proprieties. Sober, demure, well-conducted, she has fulfilled her duties with a conscientiousness which is beyond praise. When those heavy rains set in a week ago, outdoor life at once became impossible. Adèle and Ernest took seriously to their books and Mademoiselle devoted herself to them in a manner which has been absolutely exemplary. She has literally given up her whole time to their welfare, not only—so Madame Leblanc tells me—by helping with their clothes, but she has even taken certain menial tasks upon herself which are altogether outside her province as a governess. She has relieved the servants by attending to the children's bedroom; she had been making their beds and even washing their stockings and pocket handkerchiefs. She asked to be allowed to do these things in order to distract her mind from the sorrow caused by Madame's displeasure.
