Many biographies and TV documentaries have
discovered affairs, incognito dates, State secrets, wedding promises, a
press conference where Marilyn threatened to reveal things, wiretaps,
blackmails, dissimulatiions, gangsters and hired killers stories...
In many stories, the Kennedys brothers are practically interchangeables; in every case, Marilyn represented a potential weapon usable by the ennemies of the Kennedys. She would have not only written all the secrets in a mysterious red note-book, but also was about to reveal everything.Another version, supported by the biographers who think that Marilyn tried to kill herself, is that the Kennedys responsability is no more and no less important than the one of those who belonged to her life at that time.
John Kennedy as well as Robert Kennedy had had, for several years, some affairs and sexual relations in the most complete impunity. What's more, Marilyn having never publicly attacked people who had hurt her, the threat of a press conference where she would have revealed awful things about Robert Kennedy seems unlikely.
Dr Greenson flatly denied the existence of an affair between Marilyn and one or the other of the Kennedys.
