**This fascinating account of the most infamous crime of the 20th century draws on never-before-published information to reveal the Mafia conspiracy that led to the assassination of John F. Kennedy.** For the first time, this concise and compelling history seeks to answer the questions that have haunted Americans for Why and how was JFK murdered? The Hidden History of JFK’s Assassination draws on exclusive interviews with more than two dozen associates of John and Robert Kennedy, in addition to former FBI, Secret Service, military intelligence, and Congressional personnel, who provided critical first–hand information. The book also uses government files—including the detailed FBI confession of notorious Mafia godfather Carlos Marcello—to simply and clearly reveal who killed JFK. Using information never published before, the book uses Marcello’s own words to his closest associates to describe the plot. His confession is also backed up by a wealth of independent documentation. This book builds on the work of the last Congressional committee to investigate JFK’s murder, which concluded that JFK “was probably assassinated as a result of a conspiracy,” and that godfathers “[Santo] Trafficante [and Carlos] Marcello had the motive, means, and opportunity to assassinate President Kennedy.” However, it also draws on exclusive files and information not available to Congress, that have only emerged in recent years, to fully explain for the first time how Marcello and Trafficante committed—and got away with—the crime of the 20th century.
