Lovely home, lovely husband, lovely family: apart from the envy of her less contented sister everything in Dilys's rags-to-riches life is lovely, lovely, lovely. Until the day she meets a man at a railway station who is also - lovely.
As she hurtles towards either her destruction or her liberation she discovers that deceit is in the blueprint of our birth, that ancient Aunts have their own dark secrets, that envious sisters have their reasons. And that when 'Brief Encounters' meet 'Basic Instinct', the right choice, like truth, is rarely pure and never simple.
