Washington DC, 1953. The Cold War is heating up; McCarthyism, in all its fear and demagoguery, is raging in the nation’s capital, and Joseph Stalin’s death has left a dangerous power vacuum in the Soviet Union.
The CIA, meanwhile, is reeling from the discovery of a double agent within their midst. Someone is selling secrets to the Soviets, compromising missions and endangering lives around the globe. The CIA director knows any news of the traitor, whose code name is Protocol, would be a national embarrassment and weaken the entire agency. He assembles an elite team to find Protocol.
George Mueller seems to be the perfect man to help the investigation: Yale-educated; extensive experience running missions in Eastern Europe; an operative so dedicated to his job that it left his marriage in tatters. Mueller, though, has secrets of his own, and as he digs deeper into the case, making contact with a Soviet agent, suspicion begins to fall on him, as well. Paranoia and fear spreads and until Protocol is found, no one can be trusted.
