Was Dorothy Kilgallen, television star, media icon, investigative reporter, and journalist, murdered for writing a tell-all book about the JFK assassination? Through discovery of never-before-seen videotaped eyewitness interviews with those closest to Kilgallen and secret government documents, journalist Mark Shaw unfolds a murder mystery featuring suspects including Frank Sinatra, J. Edgar Hoover, Mafia Don Carlos Marcello, and a "mystery man" who may have silenced Kilgallen.
