I have just finished a book called 'whatever you love' by Louise Doughty. As I was reading it, I knew what was going to happen next and think I saw it done on TV a few years ago. A young girl is knocked down by a car, the mother vows revenge and when she finds the man who drove the car, she ends up seducing him that night! Her ex husband has a disasterous second marriage and his new wife disappears. Ring any bells?
