Yes, well, it's fair to say that Georgette Heyer was not the world's best mystery writer and the plotting in this one is not particularly strong. (I say this because I guessed the culprit early in the piece. It was just a process of elimination, as there weren't that many suspects to choose from!) But I still enjoyed listening to the audiobook of this novel. Most of the characters are unlikeable, but they are quite funny. I loved their in-depth discussions about how they could have been the murderer. I also loved Roger: he reminded me of one of the stock characters in Georgette Heyer's Regency romances: the disreputable but entertaining younger brother. I don't think Heyer's mysteries are anything like as good as her Regency romances, but for someone who grew up reading and loving those romances - or for someone with an interest in period mysteries - they still make rewarding reading.
