An emasculated corpse who opens his eyes on the autopsy table. A cell phone that starts ringing in the body of a young drug addict who died of unexplained burns. Despite fifteen years of duty in Seine-Saint-Denis, Victor Coste, police captain, is preparing for the worst. And what about these anonymous letters that reference a mysterious file: the "Code 93?" Coste will cross the limits of the job, and of reason. Author Olivier Norek is also a lieutenant of the Criminal Investigation department of Seine-Saint-Denis. Code 93, his first novel, meets the success of the public and critics with an astounding and ultra-realistic introduction to the world of crime and the police of today. The Express writes: "A story that holds in suspense until the last page. Great art of crime."
