Princess Diana’s infamous letter in which she warned she could be killed in a staged car crash was only passed to French investigators six years after her fatal collision, a new documentary claims. The film ‘Investigating Diana: Death In Paris’ refers to the so-called ‘Mishcon Note’ as it was written by the Princess of Wales’ legal adviser in 1995, and is reportedly an account of what Diana said during a meeting with Victor Mishcon and her personal private secretary at the time.
