Probably all of Jane Austen's books, because of her depictions of good manners. My parents didn't bother much, apart from teaching us how to use a fish knife correctly and how to lay the table without making it look like a restaurant, but she presented situations that showed how sensible it was to behave well in certain situations. Nowadays good manners are fairly rare, so my DD says that her DS is always winning the class prize for manners and politeness!
