I love Heyer best in full farcical mode--as she is in this book! It is true Amanda can be a bit annoying, but since she is, after all, just the Means by which Heyer contrived to get her hero and heroine together (since, left to their own devices, they are driftingly gently but inexorably apart), I do not mind her. As a heroine, she would have been tiresome: as a catalyst, she's amusing!
