It is interesting to watch the narrative change over the years around Diana.
At the time, I remember how hostile the press has started to become before he death and how they immediately turned on the royal family, demanding public displays of private grief, whilst Diana became a saint in death.
William and Harry did an interview in, I think 2017, where they both said they were glad they had walked behind the coffin, difficult though it was, and how supportive Prince Philip had been. They were grateful to have been given a choice. Harry has changed his mind on this, as is his right. I think that it shows how grief isn't a static thing and how our perspective can change over the years.
I don't know why Charles S has waited so long to write this book, 30 years later the narrative around Diana is far more complex and nuanced than Saint Diana, Dreadful Charles. He may have missed the boat if he wanted to portray his sister as the perfect victim. Certainly his ongoing hostility calls into question the reliability of his memories, particularly as grief distorts everything around us anyway.
I hope that the book is a balanced measured account of Diana's life and that the the clickbait bits in the tabloids do not reflect the whole. Diana deserves that.
After 30 years though what I believe she most deserves is to be left in peace to be privately mourned by those who actually knew and loved her. Instead I suspect we are in for a deluge of dubious revelations and reflections to cash in, once again, on her death.
