The book was a piece of total nonsense written by an author whose scholarly credentials rank as virtually non-existent.
You wonder if Kilgallen still lived past November 1965, her story about the assassination might have blown it wide open.
She had nothing and knew it- note that she spent most of the last month of her life bickering with a pair of Broadway producers when she published a review of their show while it was still in previews, which isn't exactly how you prioritize things when you do have the story of a lifetime.
