Duffy is the author of four novels. 'The Generation Game' was her debut novel, inspired by her childhood growing up in a sweet shop in Torquay. Her second novel, 'This Holey Life', is about a reluctant curate's wife. Her third, 'Bright Stars', is a modern day Brideshead, her fourth 'Betsy and Lilibet', the story of two women born on the same day - one an undertaker, the other the Queen.
