None of my husband’s family turns up to support us. Instead of a honeymoon, we have a quiet night in. My wedding bouquet is placed on his first wife’s grave. And then my new stepson tells me he’s sure his mother is still alive.

Our new home was supposed to be a chance to leave our past behind. But was moving here the worst mistake of our lives?

And when I start an affair with a stranger called Ewan, my life changes in ways I can’t begin to understand. Because Ewan breaks apart my marriage piece by piece and then he just disappears.

I can’t trust anyone, not even myself - not even the people I love.

I heard Emily before I saw her. The harsh smack of heels against cheap wooden floorboards. The loud phone calls. The incessant music. I knew Emily before I met her.

The only one who can save her. Because I know her best, and I heard everything.

One unsolved murder. A best friend determined to right the wrongs of the past. On the 21st August Tabitha Rice disappeared without a trace.

Some people think I’m jealous of my sister, but it isn’t true. I love her confidence; her free spirit. She’s the reckless one in the family, always wearing skimpy clothes and posting her life on social media. I prefer reading, walking my rescue dog and early nights in my New York apartment. It’s not that I meant to keep her a secret from my boyfriend, Bradley, but she just didn’t come up in conversation.
