From Wikipedia:

Tatort (“Crime scene”) is a German language police procedural television series that has been running continuously since 1970 with some 30 feature-length episodes per year, which makes it the longest-running German TV drama. Developed by the German public service broadcasting organisation ARD for their channel Das Erste, it is unique in its approach, in that it is jointly produced by all of the organisation’s regional members as well as its partnering Austrian and Swiss national public-service broadcasters, whereby every regional station contributes a number of episodes to a common pool.

Charlotte Lindholm is a smart, determined, and courageous detective, as well as a single mother raising her young son. Throughout the episodes she will have many romantic relationships, none of which succeed.

Of the 12 episodes, number 10  “The Smooth Death”  is unsettling because the “bad guy” wins.  Sometimes in a series, one episode will have the evildoer win only to be followed by an episode in which justice prevails. Sadly, not so with this difficult episode.

Each episode is very tense and can be unnerving to watch. If that appeals to you, then
