As we finished with the red and gold fireworks and welcomed everyone back to our house, I believed that everything would be okay. But I didn’t know who I was inviting in.

My parents got me through a horrific accident, helped me find a job I love teaching art, and even with buying my own house. But was it all built on lies? 

I thought my sister was happy. I thought what we all thought: that Annie and Dom led perfect lives in a lovely cottage in a quiet village by the sea, with flowers at the front gate and an apple tree in the garden. Everyone knew them: generous, loving Dom, creative, joyful Annie. But I never saw Annie as she sat waiting for Dom well into the night. I didn’t see her smiling through her tears. I didn’t know what the perfect couple was hiding.

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 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.
