POLICE INVESTIGATE. Forensics indicate the bodies have been buried at least thirty years, which leads the police to question the cottage's former owner - Saffy's grandmother, Rose.

OWNER QUESTIONED. Rose's Alzheimer's means her memory is increasingly confused. She can't help the police - but it is clear she remembers something.

A KILLER AT LARGE? As Rose's fragmented memories resurface, and the police dig ever deeper, Saffy fears she and the cottage are being watched.

What happened thirty years ago? What part did her grandmother play? And is Saffy now in danger? . . .
