Moscow, the Cold War, 1961. Stalin has been dead for eight years. With the launch of Sputnik, the Soviet Union's international prestige is at an all-time high. Former CIA agent Francis 'Frank' Weeks, the most notorious of the defectors to the Soviet Union, is about to publish his memoirs, and what he reveals is reportedly going to send shock waves through the West. Weeks' defection in the early 1950s shook Washington to its core - his betrayal rippled through the State Department, prompting frantic searches for moles and forcing the resignation of Simon, Frank's brother and best friend. So when a Soviet agency approaches Simon, now a publisher in New York City, with a controversial proposition to publish his brother's memoirs, he finds the offer irresistible since it will finally give him the chance to learn why his brother chose to betray his country. But what he discovers in Moscow is far more than he ever imagined.
