John F. Kennedy's murder launched a flurry of covert actions by officials to hide the fact that in November 1963 the US was on the brink of invading Cuba, as part of a JFK-authorised coup. The plan's exposure could have cost the life of JFK's coup leader - Cuban Army Commander Juan Almedia - and led to a nuclear confrontation with the Soviets, just a year after the Cuban missile crisis. But the cover-ups by these top officials also had the tragic effect of preventing a full investigation into JFK's assassination, spawning a legacy of secrecy that would impact Presidents, Congress, and US foreign policy for the next 45 years. Legacy of Secrecy reveals for the first time the secret attempts of Robert F. Kennedy and his aides to expose his brother's killers, using interviews with two dozen RFK associates and newly declassified files. It shows how RFK continued his war against the Mafia by focusing increasing attention on the godfathers behind JFK's assassination, until his own murder. RFK's associates continued his quest and almost exposed the truth on six different occasions. But like a deadly, high-stakes chess game - at the height of the Cold War - each time they were blocked by three Mafia chiefs and a handful of CIA operatives.
