From Amazon BritBox:

Emma Hedges needs to find out what happened to her mum. In a world of danger and deceit, will Emma have the nerve to follow the evidence no matter where it takes her?

From Amazon BritBox you can stream two seasons of this mystery series set in Dundee, Scotland.  Each season consists of 6 episodes. Each episode lasts about 45 minutes.

SEASON  1:

Emma (played by Molly Windsor) enthusiastically begins her new job in a forensics lab where she discovers a link to the still unsolved murder of her mother twelve years ago.  Coincidentally her team must investigate a suspicious fire in which 3 people died.  During this investigation she meets the father and son team of building contractors involved in the construction of that building.  Her relations with each of these two men could not be more opposing: she falls in love with son Daniel MacAfee (played by Martin Compston) and is afraid of the father Phil MacAfee (played by Vincent Regan).  And then the plot thickens.

Vincent Regan may be the most familiar actor in this series. Usually he plays a nice guy such as Ray Conlon in “The Bay“.  In “Traces”, however, he is a very effective bad guy.

Worth calling this season a DO NOT MISS.

SEASON 2:

Although this season begins with the trial of Phil MacAfee for murdering Emma’s mother,  this season suddenly ignores that plot and launches into the search for a serial bomber.  At least three bombs go off before the forensic scientists uncover the bomber’s identity.  Along the way there are many personality clashes and other issues.  To repeat: season 2 seems strangely disjoint from season 1, is more into scientific details, and is not as exciting as season 1.  Not exactly a “do not miss”, but still worth the watch.
