For Commandant Camille Verhoven life is beautiful. He is happily married and soon to become a father. He's always one chapter ahead. But his blissful existence is punctured by a murder of unprecedented savagery. When his team discovers that the killer has form - and each murder is a homage to a classic crime novel - the Parisian press are quick to coin a nickname... With the public eye fixed on both hunter and hunted, the case develops into a personal duel, each hell-bent on outsmarting the other. There can only be one winner. The one who has the least to lose.
