When I started research on Jacquetta Duchess of Bedford I found pretty much nothing. There was a chapter in a PhD thesis, and one essay. And yet this is the mother and grandmother of queens of England, and a major player at both royal courts of Lancaster and York. There was more magic in this story than any I have written since the more fictional novel The Wise Woman and this was because Jacquetta was descended from a family who claimed to have a water spirit in their family tree, and she was associated for all her life with the practise of witchcraft. I found her to be utterly fascinating, and I hope that historians go on to research her life in detail.
