Molly Windsor (Cheat), Laura Fraser (The Loch) and Jennifer Spence (You Me Her) are set to join Line of Duty’s Martin Compston in Amelia Bullmore’s (Scott & Bailey) new drama as three forensic scientists who aim to discover the truth behind an unsolved murder.

The crime thriller follows Emma Hedges (Molly Windsor), a new lab assistant who joins the Scottish Institute of Forensic Science and Anatomy (SIFA) and discovers a fictitious case of a murder scene that bares a striking resemblance to memories from her past.

To find answers, Emma journeys to the darkest corners of forensic science, making her cautious of who she can trust.

With the aid of Professors Sarah Gordon (Laura Fraser) and Kathy Torrance (Jennifer Spence), Emma will set out to bring the killer to justice using the forensic disciplines that have fuelled her imagination.

Traces, Alibi’s first original drama series, will be produced by RED Production Company and executive produced by Nicola Shindler.

Also joining the cast are Rebecca Gatward (Cold Feet), Mary Nighy (Silent Witness), Vincent Regan (Delicious), Laurie Brett (EastEnders), John Gordon Sinclair (Marple) and Michael Nardone (Shetland).

The six-part series airs later in 2019 and you can watch Martin Compston in the season finale of Line of Duty on Sunday at 9.00pm on BBC One.
