Traces stars Line of Duty alumni, and explores the world of SIFA, the Scottish Institute of Forensic Science.
It's being shown on crime channel Alibi, so here's everything you need to know about it - including how to watch it.
What is Traces about?
"When 23-year-old Emma Hedges returns to Scotland to take up a new position as a lab assistant at SIFA, she signs up to an online course which teaches the principles of forensic science," says the show's official synopsis.
Hedges soon discovers that the fictitious case study has a strikingly similar and shocking link to her past, and as Emma’s sleuthing takes her into darker corners and unpicks more and more secrets, it becomes clear that she should trust no-one.
"Running alongside Emma’s central story, other cases and different forensic disciplines will shine a spotlight on science’s contribution to solving the mysteries of human existence."
Who stars in it?
"Traces introduces us to three compelling and very different female characters," says the synopsis, "Emma Hedges, Prof. Sarah Gordon and Prof. Kathy Torrance - who together will use the rigours of forensics to uncover the truth about an unsolved murder case."
BAFTA award winning actress Molly Windsor stars as lab assistant Emma Hedges. She picked up the BAFTA for her role as Holly Winshaw in Rochdale grooming scandal drama Three Girls, and starred alongside Katherine Kelly in TV drama, Cheat.
Laura Fraser (The Missing, Breaking Bad) co-stars as Prof. Sarah Gordon, while Jennifer Spence (Travelers, You Me Her) is Prof. Kathy Torrance.
Co-starring opposite the female leads is Martin Compston, who will be instantly familiar to fans of similar crime shows for his time as anti-corruption cop DS Steve Arnott in Line of Duty.
He's also appeared in Mary Queen of Scots, Victoria and The Nest, but unlike in Line of Duty, Compston will be delivering his lines in his native Scottish accent here.
