It was the Anne Boleyn research. She wanted to know everything, e.g. when would she have stopped feeling her head being cut off
The nerve specialist told her the few seconds after her head had been cut off and that she would have felt her head being cut off
I was dreading how she would have translated that to the book.
I’ve read a few and I don’t remember being overly disturbed by any. Have you read the Wolf Hall trilogy because I would say Alison Weir is tamer than that?
She has written a book about Wolsey and there’s a lot of him having sex in it and that did make me squeamish
