The first instalment of the Sussexes Netflix documentary saw Prince Harry compare his late mother to Meghan, speak about unconscious bias, address the moment he decided to wear a Nazi uniform to a party, explain how he felt "harassed" during palace-organised press calls and express his hopes for his two children, Archie and Lilibet.
While the first three episodes did not throw too many noses out of joint thanks to the lack of explosive content, the final instalment - which will be available to stream on December 15 - will focus on their departure from the Royal Family and everything that has taken place since.
However, if there is one revelation that senior royals and palace officials will surely be breathing a sigh of relief over it is that Harry's upcoming memoir 'Spare' is reputed to be far less "harmful" than the series.
During an Instagram Live, former royal correspondent and associate editor of The Telegraph, Camilla Tominey, answered questions on royal events from the past few weeks and offered her view on the release of Prince Harry and Meghan's Netflix series.
After answering a series of questions and clearing up some misconceptions, TV presenter Phillip Schofield sent in a question to the livestream asking: "Is [Harry] saving the biggest attacks for 'Spare'?"
Camilla replied: "No, my understanding is the documentary is more harmful than the book and that the book is extremely closely focused on his childhood, his life and the army."

Prince Harry's memoir 'Spare' will be released early in the new year on January 10.
According to the publishers, Penguin Random House, Harry's book - which was ghost written by American novelist J.R. Moehringer - contains “raw, unflinching honesty” which is "full of insight, revelation, self-examination and hard-won wisdom about the eternal power of love over grief.”
One well-placed source said: “The very title demonstrates yet another confrontational attack on the family after claiming a desire for privacy. Palace lawyers will undoubtedly be on standby in the New Year waiting to see what is in it. If Harry’s previous allegations across numerous TV interviews are anything to go by, this will be nuclear.
When it was announced that Harry was going to write a tell-all book, he said: "I’m writing this not as the prince I was born but as the man I have become.
"I’ve worn many hats over the years, both literally and figuratively, and my hope is that in telling my story - the highs and lows, the mistakes, the lessons learned - I can help show that no matter where we come from, we have more in common than we think.
"I’m deeply grateful for the opportunity to share what I’ve learned over the course of my life so far and excited for people to read a first-hand account of my life that’s accurate and wholly truthful."
