"But come!" he exclaimed; "one must yield to reason. People like the Roubauds would not kill such a man as your father, in order to inherit sooner; or, at least, there would be indications of them being in a hurry. I should find traces of this eagerness to possess and enjoy, elsewhere. No; the motive is insufficient. It is necessary to find another, and there is nothing. You bring nothing yourselves. Then establish the facts. Do you not perceive material impossibilities? No one saw the Roubauds get into the coupé. One of the staff even thinks he can affirm that they returned to their compartment; and, as they were certainly there at Barentin, it would be necessary to admit of a double journey between their carriage and that of the President, who was separated from them by three coaches, during the few minutes it required to cover the distance, and while the train was going at full speed. Does that seem likely? I have questioned drivers and guards. All replied that long habit, alone, could give sufficient coolness and energy. In any case, the woman could not have been there. The husband must have run the risk without her, and to do what? To kill a protector who had just extricated him from serious embarrassment? No; decidedly no! The presumption is inadmissible. We must look elsewhere. Ah! Supposing a man, who got into the train at Rouen, and left it at the next station, had recently uttered threats of death against the victim----" In his enthusiasm, he was coming to his new theory. He was on the point of saying too much about it, when the door was set ajar to make way for the head of the usher; but, before the latter could utter a word, a gloved hand sent the door wide open, and a fair lady, attired in very elegant mourning, entered the room. She was still handsome at more than fifty years of age, but displayed the opulent and expansive beauty of a goddess grown old. "It is I, my dear magistrate. I am behind time, and you must excuse me. The roads are very bad; the three leagues from Doinville to Rouen are as good as six to-day." M. Denizet had risen gallantly from his seat. "I trust your health has been good, madam, since Sunday last?" said he. "Very good. And you, my dear magistrate, have got over the fright my coachman gave you? The man told me the carriage got almost upset as he drove you back, before he had gone a couple of miles from the château." "Oh! merely a jolt. I had forgotten all about it. But pray be seated, and, as I just now said to Madame de Lachesnaye, pardon me for awakening your grief with this frightful business." "Well, as it has to be done----How do you do, Berthe? How do you do, Lachesnaye?"
