Millions watched the CBS 60 Minutes special on Jack Barsky in 2015. Now the Soviet KGB agent tells his story of gut-wrenching choices, appalling betrayals, his turbulent inner world, and the secret life he lived for years without getting caught. In October 1978, a Canadian national named William Dyson stepped off a plane at O'Hare International Airport and proceeded through customs. Two days later, William Dyson ceased to exist. The identity was a KGB forgery, used to get their young, ambitious East German agent into the United States. The plan succeeded, and the spy's new identity was born: Jack Barsky. He would work undercover for the next decade, carrying out secret operations during the Cold War years -- until a surprising shift in his allegiance challenged everything he thought he believed in."
