The way Diana found out about Prince Charles's affair with Camilla is heart-wrenching
When it comes to royals scandals, it doesn't get much bigger than Prince Charles's affair with Camilla Parker Bowles while he was married to Princess Diana.
It came to overshadow their marriage - but for a long time Diana wasn't aware of what was going on.
It was only when she made an accidental discovery that she realised that that her husband was being unfaithful.
In an interview in 1997, the year she died, Diana revealed that two weeks before their wedding, she'd stumbled across a personalised bracelet that Charles had had made for Camilla.
"I was still too immature to understand all the messages coming my way," Diana recalled.
"And then someone in his office told me that my husband has had a bracelet made for her.
"I walked into this man's office one day and I said, 'Ooh, what's in that parcel?'"
The staff member told Diana not to look at it but she couldn't resist.
"So I opened it and there was the bracelet. I was devastated, and I said 'Well, he's going to give it to her tonight'.
"So rage, rage, rage. You know, 'Why can't you be honest with me?'
"But no, absolutely cut me dead.
"It was as if he’d made his decision, and if it wasn't going to work, it wasn't going to work."
"He'd found the virgin, the sacrificial lamb - and in a way he was obsessed with me, but it was hot and cold, hot and cold, you never knew what mood it was going to be, up and down, up and down."
Camilla wore the bracelet publicly for years, The Mirror reports.
