“Because, madame,” said M. Hautet, with calculated brutality. “A man tells to his mistress what he does not always tell to his wife.” “Ah!” she sprang forward. Her eyes flashed fire. “Monsieur, you insult me! And before my daughter! I can tell you nothing. Have the goodness to leave my house!” The honours undoubtedly rested with the lady. We left the Villa Marguerite like a shamefaced pack of schoolboys. The magistrate muttered angry ejaculations to himself. Poirot seemed lost in thought. Suddenly he came out of his reverie with a start, and inquired of M. Hautet if there was a good hotel near at hand. “There is a small place, the Hotel des Bains, on this side of town. A few hundred yards down the road. It will be handy for your investigations. We shall see you in the morning then, I presume?” “Yes, I thank you, M. Hautet.” With mutual civilities, we parted company, Poirot and I going towards Merlinville, and the others returning to the Villa Geneviève. “The French police system is very marvellous,” said Poirot, looking after them. “The information they possess about every one’s life, down to the most commonplace detail, is extraordinary. Though he has only been here a little over six weeks, they are perfectly well acquainted with M. Renauld’s tastes and pursuits, and at a moment’s notice they can produce information as to Madame Daubreuil’s banking account, and the sums that have lately been paid in! Undoubtedly the _dossier___ is a great institution. But what is that?” He turned sharply. A figure was running hatless, down the road after us. It was Marthe Daubreuil. “I beg your pardon,” she cried breathlessly, as she reached us. “I—I should not do this, I know. You must not tell my mother. But is it true, what the people say, that M. Renauld called in a detective before he died, and—and that you are he?” “Yes, mademoiselle,” said Poirot gently. “It is quite true. But how did you learn it?” “Françoise told our Amélie,” explained Marthe, with a blush. Poirot made a grimace. “The secrecy, it is impossible in an affair of this kind! Not that it matters. Well, mademoiselle, what is it you want to know?” The girl hesitated. She seemed longing, yet fearing, to speak. At last, almost in a whisper, she asked: “Is—any one suspected?” Poirot eyed her keenly. Then he replied evasively: “Suspicion is in the air at present, mademoiselle.” “Yes, I know—but—any one in particular?” “Why do you want to know?” The girl seemed frightened by the question. All at once Poirot’s words about her earlier in the day recurred to me. The “girl with the anxious eyes!” “M. Renauld was always very kind to me,” she replied at last. “It is natural that I should be interested.” “I see,” said Poirot. “Well, mademoiselle, suspicion at present is hovering round two persons.” “Two?” I could have sworn there was a note of surprise and relief in her voice.
