Being a huge Georgette Heyer fan, I was a little disappointed with this book, but I hadn't realized it was more of a mystery than a historical romance. It didn't seem as lively and witty and fast-moving as are the many other Heyer novels I've read. However, had I accepted it as a mystery going in, I believe I would have enjoyed it more than I did.
