Forty years is one of those special anniversaries when people are more inclined to remember the past. Not that Pippa Golding is taking any chances. Purporting to be a journalist researching a book about unsolved missing person cases, she brings the story of the disappearance of Daisy Burrows and Jimmy McGill back into the present, leaving those involved in the lives of the two missing people anxious and reluctant to speak with her. For her parents and brother, Daisy remains the five year old, innocent child. For the teacher, criticised for allowing a little girl to run out of the classroom and disappear, she is a reminder of a lost career. For Joey McGill, his mentally-disabled brother remains the abductor, the guilty party. Pippa believes there’s truth to uncover but what is her interest in this particular story. While her search for information continues, the five people she’s unnerved feel they’re being forced to relive that September day forty years before, when things weren’t quite as they’d seemed.
