Lucie Manneur, 18, brilliant student, is found dead in the courtyard of Saint Croix Boarding School in her pajamas with no obvious signs of sexual activity. She got out of the school with her friend and roommate Victoire Ledoyen to go to a bar, which they used to do every night. The girl had invented that her father lived in South Africa and her mother was a stewardess. Meyer and Delcourt discover that she spent all weekends with the Ledoyens.
