She believed her death was planned so Prince Charles could remarry. In one letter, she predicted dying from “brake failure and serious head injury.”
Diana wrote:
“I am sitting here at my desk today in October, longing for someone to hug me and encourage me to keep strong. This phase in my life is the most dangerous. XXXXX is planning ‘an accident’ in my car, brake failure and serious head injury.”
She also said:
“I have been battered and abused mentally for 15 years, but I feel no resentment. I am strong inside, and maybe that is a problem for my enemies. Thank you Charles for putting me through such hell and teaching me through your cruelty.”
Former butler Paul Burell’s role

The newspaper knew the blacked-out name but didn’t publish it for legal reasons.
Burrell said the letter’s contents troubled him since Diana’s death. He revealed the letters after his 2002 trial for stealing them collapsed when it came out he told the queen he took them to keep them safe.
Burrell worked for Charles and Diana from 1987 until Diana’s death in 1997 and was once called the “only man” she trusted.
Though Harry and William initially got along with Burrell, their relationship soured after Harry worked on a farm in Australia at 19.
In 2003, Burrell’s book, A Royal Duty, revealed private details that angered Harry and William, who called it a “cold and overt betrayal.”
Harry was furious with his mother’s former butler

Paul suggested meeting Harry and William to explain his book and share unseen sides of their mother’s life.
“I’d love to give them a piece of my mind,” he said.
After that, Harry and Paul clashed. In Spare, Harry accused Paul of “milking” their mother’s death for money and said A Royal Duty “made his blood boil.”
Harry recalled receiving a warning from the Palace about the “delicate matter.” He called Paul’s book a self-centered version of events and said, “My mother trusted him, but now he’s exploiting her disappearance.”
Harry wanted to confront Paul in Britain but was stopped by his father and brother.
Paul later responded from Florida, saying Harry had “changed fundamentally” and that their mother would be “appalled.”
Naughty Princess Diana letters

Princess Diana showed a cheeky, humorous side in two greeting cards sent to King Constantine II of Greece, which sold at auction for $7,000.
One card featured a naked man with the caption: “Adam came first… Men always do!” The other showed a naked woman with a joke about the “Perfect Man” — “A midget with a 10” tongue who can breathe through his ears!”
Signed warmly, “Dearest Tino, lots of love from Diana,” the cards reveal a playful side rarely seen.
The reason for sending them is unclear, but they likely reflected a private joke or conversation between friends.
Rest in peace, Princess Diana — a royal with wit and spirit.
