She vanished eleven years ago. Every year, on her daughter’s birthday, her mother received a letter: ‘You will never see each other again.’ For eleven years, few people believed she was still alive. And now, she has returned. Maxime Monceau—a gendarme by profession, a synergologist and non-verbal communication specialist by training, and, by birthright, a former member of a sect he loathes (memories of which still haunt him to this day)—joins the investigation. The story of the crime that gradually takes shape within the Annecy Gendarmerie is both terrifying and baffling. What happened to the young woman who vanished from the face of the earth for eleven years? Why does she remember nothing? Who is her abductor? Where can he be found? Who else is in danger?
