Things are going well for Matt Buchanan. After some hard times, life is peaceful as sole-charge constable for the small, isolated settlement of Haast on New Zealand's wild West Coast. He's made friends among the locals, won their trust. He keeps their little world safe. And he's working in spectacular surroundings - the fierce Tasman Sea, the dense beech forest, the dark, cold swamps, the snowy Southern Alps.

But then his much-loved predecessor, Gus, is discovered beside a river with a bullet through his head. He'd been looking into a disturbing murder-suicide from 1978: the parents' bodies were found, but not their daughter's. Suspecting a darker truth, Matt is certain the answers can't be too far away in this close-knit community. How does former forest service ranger Liam, with his gang links, fit into the story? What about Joe, the alcoholic hermit whose knowledge and intelligence seem so at odds with his appearance and lifestyle?

In this episode Gregory Dobbs chats to Chris Blake about the wild west coast of the South Island of New Zealand as the perfect setting for a dark and bloody crime thriller, how Senior Constable Matt Buchanan might have has escaped his demons, and the challenges for Chris Blake as both a serving police officer and an award-winning novelist.
