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.

The East German government has the power to officially change the truth, so when the murder of a woman is officially labeled an "accidental death," Major Karin Müller of the People's Police knows that to solve the crime, she must defy the official version of events. During the worst winter of the century, Müller sets out to untangle a web of state secrets, and in this fifth case (after Stasi 77), she must make a fateful choice that puts her family in danger.
