- For years I’d wanted to write a two-book set based on the premise: “Two men say they’re the Duke of Something. One of them must be wrong.” (Two points if you can guess where that line comes from.)
- The Lost Duke of Wyndham and Mr. Cavendish, I Presume take place concurrently, and their plots are very closely intertwined. When I began to develop these two novels, it became clear that if I didn’t want the plot or characters of one book to be dependent upon the other, I would need to write the two books simultaneously. Many scenes occur in both books, but from different points of view.
- As with The Lost Duke of Wyndham, the cover was meant to evoke a romantic movie poster. I got to pick out the cover models for this one!
- I have always been a total geek for maps, so I was very excited to be able to include some cartography in the book. The first map that Thomas and Amelia look at (the one in which Greenland looks so big) is a Mercator projection:

- Here is an example of a Mercator projection circa 1820:

- And finally, here we have a cordiform projection. This world map (below) created in 1536 by Oronce Fine (1494–1555) who was one of the first French scholars to work with cartography.

- I’ve loved the idea of the Outer Hebrides ever since I saw Barbra Streisand in What’s Up Doc? Wondering where they are?
