What's up with all these spies? Did they really love me? Have we no sense of decency?

The history of Russian espionage in the west, and especially "Illegals"--spies who operated without diplomatic cover. We get into Kim Philby and the Cambridge Five, Klaus Fuchs, the Rosenbergs, Hanssen and Ames, and the more recent clown shows.
