"Of course, I gave Lavernay a stern scolding; but he swore to me that though he had followed Mademoiselle during her evening walks, he had done it mostly without her knowledge and always without her consent; a fit of his former jealousy had seized him, but she had reprimanded him very severely and forbidden him ever to dog her footsteps again. After that he, too, appeared to turn over a new leaf. It. seemed as if his passion for Marie was beginning to burn itself out, and that we could look forward once again to the happy and peaceful days of the summer."

M. le Sous-Préfet had talked uninterruptedly for a quarter of an hour; his pompous, somewhat laboured diction and his loud voice had put a severe strain upon him. The Man in Grey had been an ideal listener. With his eyes fixed on M. Leblanc, he had sat almost motionless, not losing a single word of the prolix recital, and even now when the sous-préfet paused—obviously somewhat exhausted—he did not show the slightest sign of flagging interest.

"Now, my good Monsieur Fernand," resumed M. Leblanc, with something of his habitual, condescending manner, "will you tell me if there is anything in what I have just told you—I fear me at great length—that is not perfectly simple and even stereotyped? A young and pretty girl coming into a somewhat old-fashioned and dull household and finding a not altogether commendable pleasure in turning the heads of every susceptible man she meets! Indiscretions follow and the gossips of the neighbourhood are set talking. Admonished by her mistress, the girl is almost broken-hearted; she begs for forgiveness and at once sets to work to re-establish herself in the good graces of her employers. I dare say you are surprised that I should have been at such pains to recount to you a series of commonplace occurrences. But what to an ordinary person would appear in the natural order of things, strikes me as not altogether normal. I mistrust the girl. I do not believe in her contrition, still less in her reformation. Moreover, what worries me, and worries Madame Leblanc still more, is the amazing ascendency which Marie Vaillant exorcises over our boy Ernest. She seems to be putting forth her fullest powers of fascination—I own that they are great—to cementing the child's affection for her. For the last few weeks the boy has become strangely nervy, irritable and jealous. He follows Marie wherever she goes, and hangs upon her lips when she speaks. So much so that my wife and I look forward now with dread to the day of parting. When Marie goes I do verily believe that Ernest, who is a very highly-strung child, will fall seriously ill with grief."

Again M. Leblanc paused. A look of genuine alarm had overspread his otherwise vapid face. Clearly he was a man deeply attached to his children and, despite his fatuous officiousness, was not prepared to take any risks where their welfare was concerned. He mopped his face with his handkerchief, and for the first time since the beginning of the interview he threw a look of almost pathetic appeal on the agent of the Minister of Police.

"Otherwise, Monsieur le Sous-Préfet," said the latter, meeting that look of appeal with a quiet smile, "has nothing occurred to justify your mistrust of Mademoiselle Vaillant's good intentions?"

"Nothing at all," replied M. Leblanc with a nervous hesitation which belied his emphatic words, "except a vague sense of uneasiness—the unnatural quiet which came so quickly in the wake of the storm of a fortnight ago; and, as I say, the extraordinary pains which the girl has taken to captivate the boy: so much so in fact that, thinking perhaps Marie still entertained hopes of our complete forgiveness and thought of using the child as an intermediary with us to allow her to remain, Madame Leblanc at my suggestion spoke yesterday very firmly to the girl, and told her that whatever happened our determination was irrevocable. We felt that we could trust her no longer and go she must."

"And how did Mademoiselle Vaillant take this final decision?" asked the police agent.

"With extraordinary self-possession. Beyond a humble 'Very well, Madame,' she never spoke a word during the brief interview. But in the evening, long after the children should have been in bed, Anne—my wife's confidential maid—happened to be in the passage outside Mademoiselle's room, the door of which was ajar. She distinctly heard Marie's voice raised in almost passionate supplication: 'Ernest, my darling little Ernest!' she was saying, 'will you always love me as you do now?' And the child answered fervently: 'I will always love you, my darling Marie. I would do anything for you—I would gladly die for you——' and so on—just the sort of exalté nonsense which a highly-strung, irresponsible child would talk. Anne did not hear any more then, but remained on the watch in a dark corner of the passage. Quite half an hour later, if not more, she saw Ernest slipping out of the governess's room clad only in his little night-gown and slippers and going back to his own room. This incident, which Anne reported faithfully to her mistress and to me, has caused my wife such anxiety that I determined to consult someone whom I could trust, and see whether the whole affair struck an impartial mind with the same ominous significance which it bears for me. My choice fell upon you, my dear Monsieur Fernand," concluded the sous-préfet with a return to his former lofty condescension. "I don't like to introduce gossiping neighbours into my private affairs and I know enough about you to be convinced of your absolute discretion, as well as of your undoubted merits."

The Man in Grey accepted M. Leblanc's careless affability with the same unconcern that he had displayed under the latter's somewhat contemptuous patronage. He said nothing for a moment or two, remaining apparently absorbed in his own thoughts. Then he turned to his visitor and in a quiet, professional manner, which nevertheless carried with it an unmistakable air of authority, intimated to him, by rising from his chair, that the interview was now at an end.
