Was “What's My Line?” TV Star, media icon, and crack investigative reporter and journalist Dorothy Kilgallen murdered for writing a tell-all book about the JFK assassination? If so, is the main suspect in her death still at large?

These questions and more are answered in former CNN, ESPN, and USA Today legal analyst Mark Shaw in his book, “The Reporter Who Knew Too Much.”

 Shaw unfolds a "whodunit" murder mystery featuring suspects including Frank Sinatra, J. Edgar Hoover, Mafia Don Carlos Marcello and a "Mystery Man" who may have silenced Kilgallen. All the while presenting through Kilgallen's eyes the most compelling evidence about the JFK assassination since the House Select Committee on Assassinations investigation in the 1970s.

Author Mark Shaw joins me today on Murder Most Foul.
