Daniel Miller has just arrived at the CIA foreign station in Berlin, Germany with a clandestine mission: to uncover the source of a leak who has supplied information to a now-famous whistleblower named Thomas Shaw. Guided by veteran Hector DeJean, Daniel learns to contend with the rough-and-tumble world of the field agent: agent-running, deception, the dangers 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?
