really depends what people are after (I'm not gonna read back through 189 pages), but if you like interesting and good crime fiction then James Ellroy, if he's not already been mentioned. (He wrote the book that became the film LA Confidential.) I'd most recommend his American Tabloid trilogy, which covers about 1960 to 1972 ish, with a plot combining a mixture of events that are definitely true (JFK being assassinated, FBI spying on Martin Luther King, etc), events that are true but where the precise details he includes are debatable (the CIA supplying weapons to right wing paramilitaries in Central America etc), and things that are common conspiracy theories but doubtful (CIA involvement in JFK assassination, etc). It sort of weaves together the classic features of crime fiction (angry loner maverick cops with a dark secret, etc) with an interesting political backdrop.
