I wrote The Second Duchess in first person—actually, in dual first-person viewpoints. I deliberately chose to write Barbara in the first person because the book started out as a historical mystery, and in mysteries the first-person sleuth is more common than not. The book, of course, went on to become as much romance and “opulent intrigue” (a phrase used to describe Duchess by one of my crit group members, which I love) and character study as it was mystery, but Barbara’s first-person voice remained. Lucrezia, the second viewpoint character, sprang to the page in first person and never looked back.
That said—I am writing The Silver Casket in third person. It’s a bigger, longer, slightly grittier, more complex story and it needs a wider view. Even so, it’s hard to feel my way out of the close, heart-and-mind intimacy of first person and into the slightly more detached third person. Even a very tight, very subjective third person still means I’m looking over my character’s shoulder and not inside her skin. It’s disconcerting. I’ve found her—my lovely farouche floromancer Rinette—and I want to be one with her.
I suspect I will write the first few chapters both ways, and perhaps some strange combination of the two, until I find the right path.
