In 1970s East Berlin, Karin Müller works for the People's Police, solving crimes in the shadow of the Wall. Trying not to run afoul of the communist bureaucracy and the Stasi—the State's ruthless yet effective security force—Müller will find that her job is nearly impossible, and in these tense Cold War thrillers, the stakes could not be higher.

Sidelined from the murder squad in Berlin, Karin Müller jumps at the chance to be sent south to Halle-Neustadt, where a pair of infant twins have gone missing. But in this second outing (after (Stasi Child), Müller soon finds that in Halle-Neustadt—the pride of the communist state—she is forbidden from publicizing the disappearances, lest they tarnish the town's flawless image. Meanwhile, in the eerily nameless streets and tower blocks, a child snatcher lurks, and the clock is ticking to rescue the twins alive.
