I stare at the little girl in the photo, her big eyes looking straight at me. ‘Please,’ the woman pleads holding the photo up. ‘You have to help me. No one else will.’ Every Friday Mercy Hamilton goes to the same supermarket. But she doesn’t buy groceries. Instead, she shows a fading photo of a little girl to anyone who’ll look, begging for help to find her daughter. One Friday, Erica Fielding comes across Mercy. Touched by her story, Erica agrees to do what she can to help. But all is not as it seems. The police know of Mercy. And there’s never been a record of a missing girl matching the description Mercy gives. In fact, there’s no record of a child at all. They think Mercy might be suffering from delusional disorder and there’s nothing Erica can do. But Erica can’t stop thinking about poor Mercy. Just who is the girl in the picture if not Mercy’s missing daughter? Despite people’s warnings, Erica is drawn deeper and deeper into Mercy’s drama…. And Erica will come to realise it was a mistake she’ll pay for. Because she was the target all along. An absolutely unputdownable read that will have your heart pounding as you question everything you thought you knew. Perfect for fans of Gone Girl, Lisa Jewell and Shari Lapena.
