If Detective Frank Bennett tries hard enough, he can sometimes forget that Eden Archer, his partner in the Homicide Department, is also a moonlighting serial killer . . .
Thankfully their latest case is proving a good distraction. Someone is angry at Sydney's beautiful people - and the results are anything but pretty. On the rain-soaked running tracks of Sydney's parks, a predator is lurking, and it's not long before night-time jogs become a race to stay alive.
While Frank and Eden chase shadows, a different kind of danger grows closer to home. Frank's new girlfriend Imogen Stone is fascinated by cold cases, and her latest project - the disappearance of the two Tanner children more than twenty years ago - is leading her straight to Eden's door.
And, as Frank knows all too well, asking too many questions about Eden Archer can get you buried as deep as her past.
