Prince Charles has received a warning from Princess Diana's biographer. 

When Prince Harry and Meghan Markle stepped down from t8heir senior royal roles, they took part in an exclusive interview with Oprah Winfrey detailing the Duke of Sussex's strained relationship with his dad, Prince Charles. 

He claimed in the bombshell interview, "I didn't see a way out. I was trapped but I didn't know I was trapped."

The dad of Lilibet Diana and Archie Harrison explained, "Trapped within the system like the rest of the family."

"My father and my brother are trapped. They don't get to leave and I have huge compassion for that."

Prince Harry also revealed in the same interview that the future king stopped taking his calls before confessing that he really let him down. 

"He's been through something similar. He knows what pain feels like. I will always love him, but there is a lot of hurt that's happened."

Prince Charles Warned to Hide

But according to Princess Diana's royal biographer Andrew Morton, Prince Charles should go in hiding once Prince Harry's reported memoir comes out. 

In July, it was reported that the Duke of Sussex is writing an intimate and heartfelt memoir in a multi-million dollar deal with a publishing house. 

The book is currently untitled, but it is expected to come out in 2022. 

Penguin Random House said in a statement, "Prince Harry will share, for the very first time, the definitive account of the experiences, adventures, losses, and life lessons that have helped shape him."

However, according to Morton, the book will make Prince Charles look like a bad father.

"I think we're going to see Charles once more in the firing line."

The book will also be ghost-written by Andre Agassi, who also had a problematic relationship with his dad.

"It is written by someone who spends a lot of time investigating father-son relationships."
