This series is centred on Sofia Karppi, a detective working in Helsinki. She lives with her school-aged son and her step-daughter. Her husband was killed in a hit and run accident in Hamburg. Partnered with Sakari Nurmi, her first case involves the investigation of the murder of a woman whose body is discovered at the site of a somewhat controversial new development. Their investigation will uncover several suspects; some personal some involved in the development. The second season sees the two detectives investigating the deaths of people who were aboard a ship as a secret meeting took place; the meeting concerned a new tunnel planned to link Helsinki with Estonia. Sofia also has to deal with problems involving her children.
I enjoyed this Finnish series with its season long stories. Each case provides plenty of suspects and motives to keep the viewer guessing. While there isn't a lot of action there are quite a few tense scenes where key characters are in danger. The characters are interesting, even if Sofia might be a candidate for Finland's most neglectful mother! The cast is impressive, particularly Pihla Viitala and Lauri Tilkanen as Karppi and Nurmi. The series makes good use of impressive locations without ever feeling like it is sponsored by the tourist board. Overall I'd certainly recommend this to fans of the genre.
