I agree.
If I were William I wouldn't talk to Hazno until I found out what he'd written in his Memoir. William is bound to feature heavily and he'll be worried about how Hazno paints him.
True.
Though I wonder how much the Place is really bothered about what Harry says in this book.
If Harry had any sense.... yeah I know... he never would have mentioned the book, and would have just released it.
By now his fox has been shot on most of the stories he, his dimwit wife, and a 'general' American reader think 'juicy': something proven if it is true he is dabbling in Diana conspiracies.
About the only thing he can reveal, that isn't already known, is how many times he has tried to commit suicide... I'm guessing four, one of which was serious...
