Aberystwyth. Centuries old. A place of searing beauty. A natural crucible of colliding worlds, where history, myth and tradition come face to face with the modern and contemporary. But its panoramic vistas and quaint facade hide a multitude of sins - this is a place that lives according to its own rules, a place where grudges fester, where the secrets of the past are buried deep. Into this world steps DCI Tom Mathias. On the run from his past, our thirty-eight year old hero is a brilliant but troubled man. Having abandoned his life in London, he finds himself holed up in a trailer park on the outskirts of town - a place filled with secrets as dark and destructive as his own. His partner in crime is DI Mared Rhys. Thirty-three years old, Mared is intelligent and complex with demons of her own to conceal. Together, enigmatic outsider Mathias and hometown girl Mared form an engaging partnership. Mathias is at the heart of every story.
