"The Diana Investigations" docuseries recently revealed fresh insight that Princess Diana predicted her death.
The royal allegedly informed her lawyer that there was a plot to get rid of her by a car accident.
Diana's lawyer Victor Mischon penned down details of the conversation on a note.
Two years after informing her lawyer of the alleged plot, Diana died in a car accident.
Her lawyer subsequently handed the note to the police.
An investigation, dubbed Operation Paget, was launched to determine the letter's credibility.
The investigating officer, John Stevens, questioned Mischon for more details about the letter.
Other allegations about the death of the Princess were also checked out.
Details about Operation Paget were made public in December 2006.
