True crime podcaster Rachel Krall has come to Neapolis, a small seaside town being torn apart by a devastating trial. A local golden boy - a swimmer destined for Olympic greatness - has been accused of raping the beloved granddaughter of the police chief.

Used to being recognised for her voice, not her face, Rachel is unsettled when she finds a note on her car windshield, begging for her help. Twenty-five years ago, Jenny Stills drowned. Her sister insists it was murder.

Rachel throws herself into covering the trial, but the letters keep coming. As the past and present start to collide, Rachel uncovers startling connections between the two cases. The truth will change the course of the trial, and the lives of everyone involved.
