The second series will see the return of Molly Windsor as Emma Hedges, Martin Compston as Daniel Macafee. Laura Fraser as professor Sarah Gordon, Jennifer Spence as professor Kathy Torrance and Michael Nardone as DCI Neil McKinven. 

Based on an idea by crime writer Val McDermid, Traces allows forensic science to take centre stage, set in Scotland at the Scottish Institute of Forensic Science. 

Amelia Bullmore will return to write the second series with Jess Williams and the series will again be produced by the RED production company. 

The first series saw Hedges return to Scotland and join the Scottish Institute of Forensic Science as a lab assistant and attempt to find out the truth about her mother’s murder. 

Series two will focus on a devastating series of bombings that hits the city of Dundee, and follows the hunt to discover the identity of the mystery bomber before the next bomb goes off.

Series two of Traces will air later this year, with further broadcast details to be announced at a later date.
