A great story BUT one has to pay attention.
I left the show in German and read the subtitles in English.
The only character that I had a problem with was Annalena the cop who in charge of the murder investigation. When will script writers learn how to write for a successful, accomplished women without her coming across as less than/a bit@#. The detective is well versed in policy and procedures BUT does not get along with others. She is not a team player. At times she comes across as a bully and can come across as bias in her thought process. Towards the end of the 6th episode this was addressed. All in all she has little compassion and is all about results. And what's with asking point blank a subordinate for sex and stating that no feelings will be involved.
The other lead detective Maik is going back to his home town to conduct the murder investigation and with it comes all his baggage that he has put behind him.
I loved the filming of the series. The music. The flashbacks.
If you love a good mystery, want something non formulaic, this a good choice.
