1940 was a difficult year in Great Britain, so its not surprising the Heyer would have been off her game a little. It’s a little difficult to write engaging light romance while two brothers are in the military and that dreadful man is dropping bombs around your ears. So I forgive Heyer for not being up to her usual standard.
That being said Corinthian has its good points. A charming hero, an attractive heroine, and a silly almost brother-in-law for comic relief. Too bad they spent so much time on stagecoaches.
Oh, well. Even mediocre Heyer is better than nothing.
