1. DCI Tom Mathias - Richard Harrington
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.

2. DI Mared Rhys - Mali Harries
Detective Inspector Mared Rhys is a local girl from middleclass stock. She knows the fabric of Aberystwyth society inside out, she’s bound to the place for better or worse; this is home. Mared is young to have risen so quickly through the ranks, but she’s earned it – a combination of hard work and natural talent. She’s intelligent, perceptive and independent, she loves what she does and she gets results. She is attractive, but doesn’t trade on it, and has no patience with those who do.
