An electrifying thriller about the rise of extremism. Two ritual murders—one in Rome and one in Jerusalem—rekindles an ancient rivalry between modern-day secret societies for knowledge lost at the fall of the Third Reich. Detective Antoine Marcas unwillingly teams up with the strong-willed Jade Zewinski to chase Neo-Nazi assassins across Europe. They must unravel an arcane mystery, sparked by information from newly revealed KGB files. Inspired from the true story of mysterious Freemason files thought to hold a terrible secret, stolen by the SS in 1940, recovered by the Red Army in 1945 and returned half a century later. First in a hugely successful series that has sold over 1.5 million copies in France and is translated into seventeen languages.
