Oberleutnant Karin Müller

1975: When Oberleutnant Karin Muller is called to investigate a teenage girl's body at the foot of the Berlin Wall, she imagines she's seen it all before. But she soon realizes that this is a death like no other before it--the girl was evidently trying to escape from West Berlin. As a member of the People's Police, Muller's power in East Germany only stretches so far. The Ministry for State Security, the Stasi, assures her the case is closed, all they need to know is the girl's name. Yet they strongly discourage her from asking questions. The evidence doesn't add up, and it soon becomes clear the crime scene has been staged. But this regime does not tolerate curious minds, and it takes Muller too long to realize that the trail she's been following may lead her dangerously close to home ...

Karin Muller, side-lined from the murder squad in Berlin, jumps at the chance to be sent south to Halle-Neustadt, where a pair of infant twins have gone missing. But Muller soon finds her problems have followed her to Halle-Neustadt. She and her team are forbidden by the Stasi from publicising the disappearances, lest they tarnish the town's image. Meanwhile, in the eerily nameless streets and tower blocks, a child snatcher lurks and the clock is ticking to rescue the twins alive...

For the Stasi, it's not just the truth that gets buried… The body of a teenage boy is found weighted down in a lake. Karin Muller, newly appointed Major of the People's Police, is called to investigate. But her power will only stretch so far, when every move she makes is under the watchful eye of the Stasi. Then, when the son of Muller's team member goes missing, it quickly becomes clear that there is a terrifying conspiracy at the heart of this case, one that could fast lead Muller and her young family into real danger. Can she navigate this complex political web and find the missing boy, before it's too late?
