Rouge abattoir opens Gilda Piersanti’s Les Saisons meurtrières sequence with a wintry police investigation centered on Inspector Mariella De Luca. The title points to a violent death, and the novel develops the case through procedural inquiry, clues, and the tensions that surround a murder investigation. Piersanti’s crime fiction emphasizes methodical detection and atmosphere over spectacle, placing the reader within the rhythms of an investigation where motives and evidence emerge gradually. Its cold-season setting reinforces the bleak mood and the pressure on investigators to reconstruct a crime from incomplete traces. As the first entry in the series, it introduces the investigative world that later volumes expand while standing as a self-contained French crime novel.
