4On a stormy night in December, a tree is blown down on an isolated Devon farm. A rucksack is found caught amongst the roots - and next to it is a human skeleton. The discoveries revive memories for DI Wesley Peterson: a young hitchhiker who went missing twelve years ago was last seen carrying a similar backpack. Suddenly a half-forgotten cold case has turned into a murder investigation. Meanwhile, in the nearby village of Petherham, a famous TV psychic is found dead in suspicious circumstances whilst staying at a local guesthouse. Could a string of mysterious deaths in Petherham over a hundred years ago be connected to the recent killings? As Wesley digs deeper, it seems the dark whisperings of a Burial Circle in the village might not be merely legend after all...
