At Paris Madame Raquin had found one of her old friends, the commissary of police Michaud, who had held a post at Vernon for twenty years, lodging in the same house as the mercer. A narrow intimacy had thus been established between them; then, when the widow had sold her business to go and reside in the house beside the river, they had little by little lost sight of one another. Michaud left the provinces a few months later, and came to live peacefully in Paris, Rue de Seine, on his pension of 1,500 francs. One rainy day, he met his old friend in the Arcade of the Pont Neuf, and the same evening dined with the family. The Thursday receptions began in this way: the former commissary of police got into the habit of calling on the Raquins regularly once a week. After a while he came accompanied by his son Olivier, a great fellow of thirty, dry and thin, who had married a very little woman, slow and sickly. This Olivier held the post of head clerk in the section of order and security at the Prefecture of Police, worth 3,000 francs a year, which made Camille feel particularly jealous. From the first day he made his appearance, Thérèse detested this cold, rigid individual, who imagined he honoured the shop in the arcade by making a display of his great shrivelled-up frame, and the exhausted condition of his poor little wife. Camille introduced another guest, an old clerk at the Orleans Railway, named Grivet, who had been twenty years in the service of the company, where he now held the position of head clerk, and earned 2,100 francs a year. It was he who gave out the work in the office where Camille had found employment, and the latter showed him certain respect. Camille, in his day dreams, had said to himself that Grivet would one day die, and that he would perhaps take his place at the end of a decade or so. Grivet was delighted at the welcome Madame Raquin gave him, and he returned every week with perfect regularity. Six months later, his Thursday visit had become, in his way of thinking, a duty: he went to the Arcade of the Pont Neuf, just as he went every morning to his office, that is to say mechanically, and with the instinct of a brute.
