1. Guernon's Hidden Baby-Swapping Across Generations

   In the alpine university town of Guernon, families of hospital orderlies (the Sertys) and librarians (the Caillois) secretly exchanged newborns across generations, swapping healthy babies born in the mountain villages for the weakened children of the university's families. The murders, beginning with the librarian Rémy Caillois found mutilated in a rock face, strike people tied to this scheme, and the investigation gradually uncovers the exchanges.

2. Parallel Investigations That Converge on One Secret

   Two cases that look unrelated run in alternating chapters: a grotesque murder in the Alps and a child's desecrated grave with a school burglary in a distant town. Clues recur in both lines, so the reader senses the link before either detective does. That gap in knowledge drives the pace, and when the storylines meet, the true scale of the crime comes out in one reveal.

3. Mutilation as a Message About Identity

   The killer removes eyes and hands, the body parts most tied to identifying a person. Read this way, the mutilations stop looking like random sadism and become a signature that points to the real crime: stolen and falsified identity and lineage. The investigator who reads the wounds as language, rather than as gore, finds the motive.
