If it's the last thing she ever does, Iris will find Sophie's killer and
make her pay.
On a cold December night in Cornwall, nanny Karen Peterson disappeared
with three-year-old Sophie Flynn. The next day, the child's body was
found on a riverbank in Penhale Wood.
A year later, Sophie's mother, Iris Flynn, appears on the doorstep of
investigating officer Rob McIntyre, determined to make him reopen her
daughter's case. McIntyre has his own personal demons, but Iris hijacks
his life in order to find the woman she thinks is responsible for
Sophie's death. Following the slimmest of leads, they are soon
confronting ghosts from the past and a chameleon-like killer who will do
anything to stay hidden.
