A Bosnian arms collector goes on a rampage, a "Reichsbürger" seeks revenge, and a Muslim doctor finds herself caught in the crossfire – a crime novel based on a true story. The Kurdish doctor Roja Özen is well-integrated in the small Bavarian town of Auffing. But then the Bosnian Ayyub Zlatar, who fled from Srebrenica as a child, shoots three police officers at the station – sparing Roja, who is present. Everything points to an ISIS attack. Roja is suspected of being an accomplice, losing patients, her husband, and friends. Markus Keilhofer, raised by his grandparents, fanatical "Reichsbürger," wants Muslims to pay for the bloodbath. When he storms into a mosque armed, Roja stands in his way. Seidl skillfully intertwines the life paths of the three protagonists, culminating in a gripping finale. A highly relevant crime novel.
