Snobs by Julian Fellowes

But is life amongst the upper echelons of 'good' society all that it seems? Edith soon discovers there's much more to the aristocracy than dancing in Anabel's, shooting small birds and understanding which fork to use at dinner. And then there is Charles's mother, the indomitable Lady Uckfield, or 'Googie' to her friends, who is none too pleased with her son's choice of breeding partner. With twists and turns aplenty, this is a comical tale worthy of a contemporary Jane Austen.
