Query: In Search of the Infamous Fifth Man

SPYTIME is a fictional story which covers such historical events as the Bay of Pigs Invasion, the Cuban Missile Crisis, the assassination of Mussolini and the capture of Che Guevara in Bolivia. Many of the book's characters are real. In spite of its title the novel is not a spy story in the traditional sense but is actually written more in the style of an expose of the inner workings of the CIA.Jim Angleton remains in the background throughout much of the story while the bulk of the spy action is handled by his young protege, Tony Crespi, who is stationed in Beirut. Angleton's main obsession as Director of Counterintelligence is the search for the infamous Fifth Man who collaborated with Burgess, Maclean, Blunt and Philby.SPYTIME is an intriguing book for anyone who is interested in the Cold War and the CIA. Buckley writes with some authority about these subjects. The novel's greatest weakness is its lack of suspense and the ending is also a bit of a dud.
