The incredible story of the CIA's bizarre effort to do in Cuban leader Fidel Castro--via everything from Mafia hit men to exploding cigars--has been coming out bit by bit over the years, without raising much of a public stir. Hinckle, former Ramparts editor and current San Francisco Chronicle columnist, and Turner, a former FBI agent and co-author (with Jon G. Christian) of The Assassination of Robert Kennedy, now lay out the whole mad and ridiculous project. The Mafia connection to Cuba is straight out of Godfather Il, with big money sunk into hotels and casinos and dreams of more--all spoiled by the entry of Castro's guerrillas into Havana. The rebel victory produced two additional sets of dissidents: American officials and the Cuban political anti-Castroites who fled to Miami. Hinckle and Turner splice together the threads of the ensuing alliance--which began with the Bay of Pigs invasion, plots to sabotage Fidel's beard, secret commando units, etc., but also branched out, they allege, to include: the suspect assassination of JFK (brother Robert, an early advocate of ""getting"" Castro, then not only soured on the wilder plots but went after the Mafia); the Watergate break-in (which, notoriously, employed several veteran anti-Castroites); and the assassination of Chilean leader Orlando Letelier. The story is full of unsavory types doing unsavory things--from soldier of fortune Frank Sturgis to Richard Nixon, whom the authors depict as the mobsters' best friend. No startling revelations--most of this has been known or suspected--but plenty of vivid high-level and undercover intrigue.
