Stasi 77

Karin Müller of the German Democratic Republic's People's Police is called to a factory in the east of the country. A man has been murdered - bound and trapped as a fire burned nearby, slowly suffocating him. But who is he? Why was he targeted? Could his murderer simply be someone with a grudge against the factory's nationalisation, as Müller's Stasi colleagues insist? Why too is her deputy Werner Tilsner behaving so strangely? As more victims surface, it becomes clear that there is a cold-blooded killer out there taking their revenge. Soon Müller begins to realise that in order to solve these terrible crimes, she will need to delve into the region's dark past.
