Dear Daisy, I miss you so much. I’m sorry I broke my promise to never be separated from you. I have never given up the search for you. Your loving sister, Holly

Superintendent Jo Hamilton remembers the night all too well. Forty years ago, when she was a young constable, she was called to a domestic disturbance. Hours later, two girls, Holly and Daisy, are left behind, the only survivors of the fire started by their dad which killed him and their mother.

Against her own instincts, Jo had to leave the girls at Morley House children’s home, a Victorian building teetering on the edge of Saltdean Cliffs in Sussex. She’d tried to keep track of them but found out the sisters were separated, little Daisy adopted and Holly, the elder one, getting into trouble until one day she disappeared, never to be seen again - around the same time as another of the girls in the home fell to her death on Saltdean Cliffs, assumed a suicide. But no one ever looked too closely into the goings on at Morley.
