In an abandoned house on the outskirts of Lille, a young urban exploration enthusiast discovers the body of a man—emaciated, bound, and on the brink of death. The victim dies in the hospital a few hours later. An autopsy reveals a strange message inside his stomach: “Eternity for the chosen.” Commander Xavier Ducastaing, his partner Captain Nadia Vernois, and police academy trainee Sybille Kervasdoué suspect a link between this ritualized execution and the property’s owner—a delusional former soldier with cult-like beliefs. How long had the victim been held captive and starved? Was he a victim or a willing participant? So begins an investigation with far-reaching tentacles extending into the depths of the darknet—a trail leading back and forth between past and present, scrutinizing the toxic relationship between a convicted murderer and his prison visitor. A harrowing investigation into the darkest recesses of the human soul.
