"Working with thousands of previously unreleased documents and drawing on more than one thousand interviews, with many witnesses speaking out for the first time, Joan Mellen revisits and extends the investigation of late New Orleans district attorney Jim Garrison, the only public official to have indicted a suspect in John F. Kennedy's murder."

"Garrison began by exposing the contradictions in the Warren Commission Report, which concluded that Lee Harvey Oswald was an unstable pro-Castro Marxist who acted alone in killing President Kennedy. A Farewell to Justice reveals that Oswald, no Marxist, was in fact working with both the FBI and the CIA, as well as with U.S. Customs, and that attempts to sabotage Garrison's investigation reached the highest levels of the U.S. government. Garrison interviewed individuals involved in the assassination ranging from CIA operative Clay Shaw and CIA contract employee David Ferrie to a Marine cohort of Oswald named Kerry Thornley, who turned out also to have had ties to the CIA.

Garrison's suspects included CIA-sponsored soldiers of fortune enlisted in assassination attempts against Fidel Castro, an anti-Castro Cuban asset, and a young runner for the conspirators, who comes forward fully here for the first time." "Building upon Garrison's formidable effort, Joan Mellen uncovers decisive new evidence and clearly establishes the intelligence agencies' roles in a president's assassination and its cover-up, set in motion well before the murder."--Jacket.
