Before she went out, she reminded Vitalis that this was his last day in her service, that when she returned she would expect to find him gone. It was after seven when she left the house. The lovers had no time to lose; the deed must be done immediately on the mother's return. They arranged that Vitalis should get rid of the shop-boy, and that, as soon as he had gone, Marie should shut and lock the front doors of the two shops. At one o'clock Madame Boyer came back. She expressed her astonishment and disgust that Vitalis still lingered, and threatened to send for the police to turn him out. Vitalis told the shop-boy that he could go away for a few hours; they had some family affairs to settle. The boy departed. Madame Boyer, tired after her long morning in the town, was resting on a sofa in the sitting-room, at the back of the milliner's shop. Vitalis entered the room, and after a few heated words, struck her a violent blow in the chest. She fell back on the sofa, calling to her daughter to come to her assistance. The daughter sought to drown her mother's cries by banging the doors, and opening and shutting drawers. Vitalis, who was now trying to throttle his victim, called to Marie to shut the front doors of the two shops. To do so Marie had to pass through the sitting-room, and was a witness to the unsuccessful efforts of Vitalis to strangle her mother. Having closed the doors, she retired into the milliner's shop to await the issue. After a few moments her lover called to her for the large cheese knife; he had caught up a kitchen knife, but in his struggles it had slipped from his grasp. Quickly Marie fetched the knife and returned to the sitting-room. There a desperate struggle was taking place between the man and woman. At one moment it seemed as if Madame Boyer would get the better of Vitalis, whom nature had not endowed greatly for work of this kind. Marie came to his aid. She kicked and beat her mother, until at last the wretched creature released her hold and sank back exhausted. With the cheese knife, which her daughter had fetched, Vitalis killed Madame Boyer.
