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? As more victims surface, it becomes clear that there is a cold-blooded killer out there taking their revenge. But are the Stasi really working with her on this case?
A secret state. A dark conspiracy. A terrible crime.
