All I ever wanted was to keep my son safe. I married the perfect husband, built the perfect home. I’ve tried to give Finn the life I never had. Everything was going so well. Until now. It’s just small things at first - a punctured tyre, an open gate that I'm sure I locked. But then I see the photograph of two young girls, and a night I’ve tried to forget. I know I have to stop pretending that nothing is happening. I can’t escape the truth. Someone knows my secret. But what do they want from me?

The phone rings. What Eva doesn’t realize is that the call will signal the end of what she knows to be true. The end of trusting her family. And the end of everything keeping her safe. The phone call is from a hospital hundreds of miles away. A woman has been admitted with a serious head injury, saying she’s Eva’s older sister. A sister Eva never knew she had. Whose name - Nancy - has never once been mentioned by her parents. It seems impossible. Could the two people who brought Eva up have lied to her for her whole life?

I made a new friend at playgroup today. She’s different from the other mothers. She feels like someone I can trust. Someone I can confide in. But there are some things I can’t tell her. Things I can’t tell anyone. Because I have a secret that no one else knows. One that still haunts my dreams, wakes me up in cold sweat at night. Even another mother would never understand. Unless, of course, she’s hiding something, too.

Just four words were printed in the card. He doesn’t love you. I’ve been dreaming about this day - marrying Adam, my childhood sweetheart, who I’ve loved for 18 years. I didn’t realize the perfect day would turn into the perfect nightmare. I was so excited to send out the wedding invitations, carefully writing everyone’s names on thick cream paper in beautiful cursive script. I had no idea I was inviting someone to destroy our marriage. 

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven.

I wrap my arms around the tree trunk, pressing my cheek against it until the bark digs in and the missing poster is finally secured. I try not to look at the photograph on it. At the features so similar to mine. Perhaps this will be the year someone comes forward. Were crucial mistakes made by detectives from the very beginning? Could the pressure of living two lives have led my sister to run away - or even end it? Or did someone in her tight circle of friends and family have reason to want her gone? Someone out there must know something.
