Twisted Minds by Hillary Norman (Paperback)

Upon entering the Hampstead house once owned by his new wife’s late husband, Matthew Gardner quickly comes to the realisation that life with Caroline will be far more challenging than he initially anticipated. Among Caroline’s three teenage daughters, Flic and Imogen, who present themselves charmingly in public, harbour a deep loathing for him. They believe that life would be considerably smoother if their mother could see Matthew from their perspective. However, Flic and Imo, displaying tendencies towards sociopathy, are unwaveringly committed to eliminating their stepfather and employ chillingly ruthless methods to achieve their goal.
