Oberleutnant Karen Muller

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. 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.

Dresden, East Germany, 1980. A man's body is found buried in concrete at a building site in the new town district. When People's Police Homicide Captain Karin Müller arrives at the scene, she discovers that all of the body's identifiable features have been removed - including its fingertips. The deeper Müller digs, the more the Stasi begin to hamper her investigations. She soon realises that this crime is just one part of a clandestine battle between two secret services - the Stasi of East Germany and Britain's MI6.
