Isabel Dalhousie is sanctimonious bitch!
She is condescending to her housekeeper.
She slut shames her niece.
She is a snob about her so-called work which she never seems to do.
She thinks her 2 year old son is a food snob because he likes olives, sardines and gherkins.
She justifies her buttinksky behavior by thinking she has the power to make other people happy.
She ponders how lucky and happy she is and assumes those who were not blessed with a trust fund and good education lead lives of quiet desperation.
IMHO the real hero of this book is Isabel's niece Cat:
