Daniel Miller, an undercover agent who has just arrived at the CIA station in Berlin, Germany, has a clandestine mission: to determine the identity of a now-famous whistleblower masquerading as "Thomas Shaw." Guided by jaded veteran Hector DeJean, Daniel learns to contend with the rough-and-tumble world of the field officer, agent-running, deception, danger and moral compromises. As he dives deeper into the German capital's hall of mirrors and uncovers the threads of a conspiracy that leads back to Washington, Daniel wonders: Can anyone ever be the same after a posting to Berlin?
