Private, the world's most respected investigation firm, has branches around the world, each staffed with the smartest, fastest, and most advanced agents, who have cutting-edge forensic tools that not even the most powerful governments possess.
At Private Berlin, agent Chris Schneider has disappeared. Chris had taken a secretive personal leave and hadn't spoken to anyone from the office in days. The Private team retraces his footsteps to the cases he was investigating before his disappearance: a billionaire suspected of cheating on his wife, a world-famous soccer player accused of throwing games, and the owner of a seedy nightclub. They were the last people to see Chris--and they're all suspects. And someone is lying.
The Private team is led to an abandoned Nazi slaughterhouse where all hope vanishes. As Private digs further into Chris's past, a terrifying history is revealed, and they begin to suspect that someone very dangerous and very depraved is responsible for Chris's disappearance. And he's not finished in Berlin.
