As Holly takes control of the investigation, the trail leads her straight into the path of Kyra Ford, a local academic and documentary presenter, who Holly hasn’t seen since their friendship imploded at school fifteen years earlier.

Kyra isn’t just a witness to the crime – she’s also a reminder of a betrayal Holly has spent her entire adult life trying to forget. As the two women circle each other against a backdrop of festering hatreds and hidden abuses of power, Holly must confront both her past and a killer who may be planning to strike again.
