I think it is very VERY brave to write about real people who are still very much alive and very much in the public eye to the point we feel like we "know" them. I just cannot picture Her Majesty behaving this way. Nor the descriptions of Sir David Attenborough. I get that it's fiction, but this just feels a stretch, sorry. It would have been better to use lesser royals or people not quite so in the public eye already.
So, yeah, not for me on this one.
