Besides her novels, DDM wrote some non-fiction, mainly biography. I mentioned Vanishing Cornwall at the start of this week, and today I bring your attention to her other works.
503: The Du Mauriers.
This is the biography of some of her ancestors, which she intended to write "like a novel".
524: The infernal world of Branwell Bronte.
DDM was interested in the Brontes, but decided to focus her attention on Branwell, a much maligned character. I found this book intensely interesting because I had read so much about the sisters but very little about him.
529: Golden lads.
Again, DDM focuses on a character hidden in the shadows, and writes about Anthony Bacon, the elder brother of the more famous Francis.
523: The winding stair.
This builds on her research for the earlier Golden Lads, but focuses this time on Francis Bacon.
