After La Faussaire [The Counterfeiter], a finalist for the Elle Crime Readers' Prize in 2022, Patricia Delahaie delivers an intimate and powerful reinterpretation of a tragic crime from 1974, refracted through the lens of a mother-son relationship of rare sensitivity and cruelty. Loïc, 20, knows that a monster lives within him. One Pentecost Monday, the beast is unleashed when he sees an 8-year-old girl in a white dress. Her body is found two days later. Loïc faces the death penalty. His mother, Louise, believes this is a terrible mistake. But in trying to exonerate him, is she leading him to the scaffold?
