sounds interesting, do the royals know?

This book sounds quite interesting, especially as the release of Phillips 'The Crown' episodes are being released. I am hoping the book is fearless in its explaination and characterisation, but fear it may be condensed or even diluted to please audiences. after the first impressions read I see both a concentrated and diluted version of the character and wonder if this is part of the structure.

I would be interested to see how this develops.
