Laura Dean, a curator, is discovered in a shallow grave in remote woodland. Mathias and his team must delve into the young victim's life to unearth some shocking secrets. Meanwhile, Prosser - still reeling from the death of Iwan Thomas - calls on the help of retired Chief Inspector Robert Owen.

From the windswept sand dunes of the coastline to the badlands of the hinterland, this is a detective drama with pace, poetry and scale. A world of Blood, soil and belonging. A place that lives by its own rules: a natural crucible of colliding worlds where history and myth meet the modern and contemporary. Into this world steps DCI Tom Mathias. On the run from his past, a brilliant but troubled man. Having abandoned his life in London, he isolates himself on the outskirts of town – a town filled with secrets as dark and destructive as his own.
