One of the unexpected advantages of ebooks: Replacing the renamed characters with their originals. (The characters and the author were renamed when the series moved from HarperCollins to Kensington. I read the first of the new books in paper, and the new names threw me off the entire time.)
I'm not sure how this would work for people not already invested in the Rannoch/Fraser marriage, but I enjoyed this bit of backstory: the decisions and emotions (and denied emotions) that led to their marriage, and a mystery for them to solve. As with Vienna Waltz
, the mystery neatly sheds a light on other romances and marriages in the same milieu, with especial attention to the constraints placed on women and the adaptations they made.
