Why did I love this book?
This is the most brilliant nonfiction spy book I have ever read.
It is a juxtaposition of oxymoronic proportion: CIA agent Aldrich Ames, who became a KGB mole and betrayed his country for money, and KGB agent Oleg Gordievsky who became disillusioned with the Soviet regime and risked his life by working closely with MI6, in the process very likely preventing the outbreak of a nuclear war.
Where both spies crossed paths without knowing it when Ames betrayed Gordievsky, who was recalled to Moscow. He barely escaped death and prison but was closely watched. The story of his escape from the USSR is better than any scene in a James Bond movie. This is a page-turner.
