Twisted Minds — Hilary Norman

From the day he sets foot in the Hampstead house, Matthew Gardner realises that life with his new wife, Caroline, is going to be rougher than he'd hoped. Two of her three teenage daughters, Flic and Imogen - charming to him in public - actually loathe him. If only their mother could see Matthew through their eyes, the girls feel, life would be so much easier. And the two girls are utterly determined to get rid of their stepfather, and chillingly ruthless in their methods.
