DCI Mathias must solve the case of the murdered Aron Bowen, but he must deal with feuding family members and runaway teenagers first. Will he discover the truth of the matter or will the person that's stalking him get in his way?
Mathias is under pressure. His wife Meg has turned up in Aberystwyth and he's under investigation by the IPCC following the death of Mari Davies at the end of the last episode. When a bus driver is found shot dead on an isolated mountainside, the investigation provides a welcome escape.
