The investigation of two brutal Marseilles murders by Senior Inspector Gerard de Rochenoir of the elite French National Police unearths a complex art fraud scheme involving a trove of valuable paintings stolen by the Nazis during World War II. Balancing his new American love, Wisconsin native Catherine York, in one hand and his old nemesis, the beautiful Russian assassin Sofia Mostov in the other, Inspector de Rochenoir must act quickly before the art disappears, or worse, the Mexican drug cartel adds him to their increasing body count.
