Olivier Norec is compared to the best masters of the crime genre, Jo Nesbø and Jean-Christophe Grange. He brilliantly combines lush naturalism with subtle psychologism. And only real masters can do this task... Working for a long time in the homicide department of the police, Captain Victor Cost has seen everything. But recent events have literally knocked the ground out from under his feet. First, right during the autopsy inside the corpse of a man who died from unexplained burns, the phone rang. Then another body, thought to be dead, came to life. And finally, Kost began to receive anonymous letters with detailed details of recently committed crimes. The Parisian suburb of Seine-Saint-Denis, of course, has a bad reputation, but nothing like this has ever happened here...
