Much has been written about the notorious British spies Guy Burgess, Donald MacLean, Kim Philby, Anthony Blunt, and John Cairncross, known collectively as the Cambridge Five - but never before from the Soviet side. In this enthralling account, Yuri Modin - their KGB controller, protector, confidant, and link to Moscow - offers unique insight into the true characters and intrigues of the legendary five. Modin reveals previously unknown details about how the Cambridge spies passed on their information and what they provided to the Soviet secret service. In vivid descriptions based on firsthand knowledge, he reveals how Burgess and MacLean made their spectacular escape to Moscow, the games Melinda MacLean played with both sides before defecting with her children. What pushed Philby to crack in 1983 and flee to Moscow as well, and how the Cambridge spies fared in the U.S.S.R.A real-life John Le Carre Thriller, this book provides a fascinating new view into one of the cold war's hottest chapters.
