As bodies continue to fall and the past bleeds into the present, Dr Alan Twist must confront a killer no one can see and a crime that defies logic.

Renowned sleuth Dr Alan Twist and his partner Inspector Hurst go to the eerie landscape of Dartmoor to investigate. But invisible killers are hard to bring to justice…
