Why is "What's my line? TV star and Pulitzer-Prize-nominated investigative reporter Dorothy Kilgallen, one of the most feared journalists in history? Why has her threatened exposure of the truth about the JFK assassination triggered a cover-up by at least four government agencies and resulted in abuse of power at the highest levels? "Denial of justice", written in the spirit of bestselling author Mark Shaw's gripping true crime murder mystery. The reporter who knew too much, tells the inside story of why Kilgallen was such a threat leading up to her unsolved murder in 1965. Shaw includes facts that have never before been published, including eyewitness accounts of the underbelly of Kilgallen's private life, revealing statements by family members convinced she was murdered, and shocking new information about Jack Ruby's part in the JFK assassination that only Kilgallen knew about, causing her to be marked for danger. Peppered with additional evidence signaling the potential motives of Kilgallen's arch-enemies J. Edgar Hoover, mobster Carlos Marcello, Frank Sinatra, her husband Richard, and her last lover, "Denial of justice" adds the final chapter to the story behind why the famous journalist was killed, with no investigation to follow despite a staged death scene.
