All the neighbours were laughing, drinking out of plastic glasses and getting along. I almost felt happy.

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. 

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.
