Alice Lang was wearing her favourite scarlet dress when she disappeared twenty-five years ago, and her memory still casts a long shadow.
The past was like water.
Once the tide turned, you couldn't hold it back.
In the long, hot summer of 1995, twenty-two-year-old Alice Lang rents a caravan on a holiday park on the outskirts of the lively holiday resort of Severn Sands.
She befriends Marnie, a shy, damaged little girl whose father is the park's caretaker and whose mother died a few months earlier.
