Marilyn had attempted suicide before but luckily got help in time. I never really bought the conspiracy theories, although I thought it *might* be possible considering who she was dating, but I always thought it was another suicide attempt that she didn't get medical help to save her life this time. But the new diary discovered where she talks about her fear of Peter Lawford (JFK's brother-in-law) is pretty chilling. She was genuinely afraid of him: "(There is a) feeling of violence I've had lately about being afraid of Peter he might harm me, poison me, etc. why -- strange look in his eyes -- strange behavior."
