"In the mid-1970s, the CIA and KGB watched Karel Koecher closely--they were both convinced he was working for the enemy. And they were both right. Traveling with his wife, Hana, Koecher posed as a Czechoslovak asylum seeker and arrived in the US as a Communist sleeper agent. After parlaying a doctorate from Columbia into a job at the CIA, Koecher proceeded to operate as a double agent at the height of the Cold War. Using newly declassified documents, interrogation tapes, and extraordinary firsthand accounts from the Koechers themselves, Cunningham reconstructs their double lives and the fading Cold War, where a strange moral fog made it hard to know what truth was being fought for, and to what end."--,Provided by publisher.
