A fast-paced and twist-filled psychological thriller from the author of The Couple's Revenge, The Perfect Nurse and the #1 bestseller, The Doctor's Wife.

I've never liked my next-door neighbour, Tanya, but I'm shocked when I discover she is having an affair. She doesn't seem the type, plus her husband, Joe, is gorgeous, so why would she risk her marriage?

With her secret out, I have to decide what to do next. My husband, Spencer, wants me to stay out of it. He says it's none of my business and he might be right. But news travels fast on a street as sleepy as mine and sordid secrets aren't safe in suburbia...

I can't help it. I have to get involved. I believe I am doing the right thing, only to discover, to my horror, that my neighbour is not the only one capable of making a mistake. I am too, as are the people closest to me, and as things get out of control and multiple marriages are at stake, I'm going to wish I never found out about my neighbour's affair...
