From MHz Choice:

Based on the international best-selling mystery novels by Mari Jungstedt, the blockbuster German crime series The Inspector and the Sea is set on the idyllic Swedish island of Gotland. Walter Sittler stars as Robert Anders, a laid-back German police inspector who has moved to the island to be with his Swedish wife, Line, and their two children.

From MHz Choice you can stream 2 seasons of this German production that takes place in Sweden.  Each season offers 6 episodes each of which lasts 1.5 hours.

Each episode is self-contained although the family theme continues throughout both seasons. In fact all the stories center around the Anders family and their social group such as friends, relatives, and their children’s school society.  Throughout Robert Anders and his wife Line and their children have their problems, the worst of which is that Robert is so busy with his detective work that he somewhat neglects his family. In my experience this “neglectful detective” theme is present  in the majority of such TV series.

After watching a few episodes, Kathy and I find that the Swedish society, at least as it is portrayed in this series, is somewhat ugly: high school children are as entitled and cruel as their unfaithful parents.

Despite the defects of the portrayed Swedish society, the plots, characters, and acting (for the most part) are excellent and make watching such long episodes well worth the effort.
