This is an interesting book for me since the logic of the narrative and the characters involved in the story made me look at the real life evidence for the accidental death of Amy Dudley. When I was writing the novel it was widely accepted that she had broken her neck as a result of a fall. It seemed to me that murder was a far more likely cause, and you can read the novel to see who I suspect. It was very exciting when, long after publication, the original documents of her inquest were found showing that she died from blows to the head made by a weapon. Amy Dudley was indeed murdered, but we still don't know who was the murderer.
