An exposé by a former Czechoslovak intelligence officer of Soviet and East European covert operations against the West. Going well beyond the author's personal experience-he left Czechoslovakia in 1968-the book ranges over the entire field (forgeries, black propaganda, front organizations, recruitment of agents, penetration of Western institutions, terrorism, assassinations, aid to revolutionaries, and so on), with many illustrative cases and items of interest, but also with a tendency to write the KGB's role as larger than life.
