Ann Forestier, the companion of police officer Verovain, is the only witness of a robbery in a jewelry store in Elysian Fields, having miraculously escaped the brutality of the thief. Shocked by the attack, police officer Verovain throws himself body and soul into this investigation, which becomes a personal matter, as the thief, a marked criminal of rare violence, is seeking Ann to kill her...

The two men are involved in a frantic chase, with Ann at stake. Verovain, feeling his own life threatened, becomes violent and ruthless himself, reaching the point of renouncing all his principles... The roles between them begin to intricately intertwine; who is ultimately the hunter and who is the prey?

Cold atmosphere, sharp writing, unexpected plot development: Pierre Lemaitre - awarded the Goncourt Prize for the novel "Au revoir là-haut" - has imposed his style and talent in noir literature.
