The Monomaniac by Émile Zola

The following day, a Sunday, five o'clock in the morning had just struck from all the belfries of Havre, when Roubaud came down under the iron marquee of the station, to resume duty. It was still pitch dark; but the wind, blowing from the sea, had increased, and drove along the haze, smothering the hills which extend from Sainte-Adresse to Tourneville; while westward, above the offing, appeared a bright opening, a strip of sky, where shone the last stars. The gas-lamps under the marquee were still alight, but looking pale in the damp chill of this matutinal hour. Shunters were engaged in making-up the first train for Montivilliers, under the orders of the assistant station-master on night duty. The doors of the waiting-rooms had not yet been opened, and the platforms stretched forward, deserted, in this drowsy awakening of the station.

As Roubaud left his apartments, upstairs, over the waiting-rooms, he found Madame Lebleu, the wife of the cashier, standing motionless in the middle of the central corridor, on which the lodgings of the members of the staff opened. For weeks past this lady had been in the habit of getting up during the night to watch Mademoiselle Guichon, the office-keeper, whom she suspected of carrying on an intrigue with M. Dabadie, the station-master. As a matter of fact, she had never surprised the least thing, not a shadow, not a breath. And, again on this particular morning, she had quickly returned to her own quarters, taking no news back with her, save the expression of her astonishment at what she had caught sight of in the rooms occupied by the Roubauds, during the two or three seconds the husband had required to open and shut the door.
