Having the perfect life may be far more dangerous than you could ever believe.

From the author of the Midsomer Murders novels comes a spine-chilling domestic thriller about jealousy and revenge. Having the perfect life will always come at a price.

Roz Gilmour is a happy woman with two children, a loving husband, a successful career as a local radio presenter and a comfortable home in North London. Sometimes she can't believe just how fortunate she is. But a woman who has everything has everything to lose, and Roz's luck is about to change...

Not everybody is as content as Roz Gilmour. There are people who dislike her - if only because of the apparent ease and success with which she lives her life. And one of them is insane. A fame-hungry stranger whom Roz has unwittingly snubbed. A man who is dangerously delusional and spiralling out of control. A man who will stop at nothing to get his revenge. Whatever it takes . . .
