Security agent Christopher Kruse lost his wife and young daughter in the south of France. In Come Barbarians he investigated and stopped the people responsible for their deaths. He has remained in France working for the ambitious mayor of Paris, wandering streets haunted by his lost family and watching over a woman and her daughter. But when a charismatic politician is murdered by a grenade attack in the Jewish quarter, Kruse catapults back into the maelstrom of organized crime and dirty politics. A young woman named Zoe, working for a shadowy division of the French clandestine services, hires Kruse and his old colleague and mentor Tzvi to hunt down and assassinate the killer. The mission leads him not to redemption but down a rabbit hole of deception, violence and unlikely romance.
