From MHz Choice:

Criminalist Viola Delbrück and Detective Burkhard “Butch” Schulz are mismatched investigators in this atmospheric German crime drama set in the mountains of Upper Lusatia.

From MHz Choice you can stream one season consisting of 6 episodes. Each episode lasts about 1.5 hours and is a complete story. German with subtitles.

Running through the 6 episodes are several themes, the most important being the fact that Viola’s former husband is stalking her and determined to win her back.  Viola is an intelligent and sincere detective who tries to follow the rules.  Detective “Butch” on the other hand is a real pain-in-the neck who is most often rude but underneath  the coarse surface is, in his own way, a caring person.

Well done set of engrossing stories.
