Detective Chief Inspector Tom Mathias arrives in Aberystwyth after ten years at the London Met. A man on a journey to recovery, a man cast into a wilderness of his own making. Flawed but brilliant, Mathias has faced death and carries the scars to show it. He may not be able to bring back the dead, but he is compelled to find justice for the living. However unorthodox his methods, this brilliant, impulsive but very human man earns our trust and confidence as - time and again - he leads us to the truth.
