When the putrid smell oozing out of an old mine shaft in the Cambrian hills' 'green desert' of Wales turns out to be a corpse, DCI Evan Warlow and his team quickly slip into gear.

But this is no pot-holing adventure gone wrong. Soon, Evan and the team are hunting for another missing person and discovering ghosts from the past that no one wants to confront. With the team stretched and confronting their own demons, DCI Warlow has his work cut out in unravelling a web of manipulation and lies.

Yet there is more than one victim here. And unless he can find a way to the truth and quickly, someone else is going to fall foul.
