TV tonight: dramatic twists abound in forensics crime drama

Traces

9pm, BBC One

The dramatic twists abound in this series starring Molly Windsor as forensics student Emma. She soon discovers that the fictional case study she is learning about refers to her own mother, who was murdered when Emma was seven and whose killer was never found. We open on the revelation, which prompts her to reconnect with her estranged father, Drew (John Gordon Sinclair), while questioning her course tutors Sarah Gordon (Laura Fraser) and Kathy Torrence (Jennifer Spence) on their unsettling choice of topic.

The Cabins
