'Ava tells me she's told you things you shouldn't know. Let me tell you this: you never tell anyone - not in my lifetime.' This is the warning that Michael Munn received over the telephone from Ol'Blue Eyes himself when he was spending time at Ava Gardner's house one day. Suffice it to say that he has never spoken to anyone about the contents of this book until now, after Frank Sinatra's death. Sinatra: The Untold Story is an extraordinary book that gives us an insight into the darker side of Frank's life - in particular his dealings with the Mob, and how he made a secret pact with the FBI to nail Chicago Mob Boss Sam Giancana as the man behind the conspiracy to kill Marilyn Monroe. The author unearths new evidence that contradicts the accepted accounts of Monroe's death and inevitably implicates the Kennedies, the FBI, and CIA and the Mafia. We learn how Sinatra feared for Monroe's safety after being shown photos of a drugged and drunk Monroe by Giancana. And how Sinatra was questioned by the FBI after Monroe's death. And how Giancana then sent Sinatra the skin of a lamb's head (signifying that he was soon to be killed) for his part in the FBI investigation. The author tracks Sinatra's vendetta against Giancana and his struggles to get free from the Mafia's control in later life. This fascinating biography contains exclusive material and has extremely wideranging implications.
