A shooting spree shakes Southern Hesse: Several people die when a man opens fire from a dark limousine. The police arrive quickly, the area is cordoned off, and tight controls bring traffic to a standstill. Criminal Chief Inspector Robert Krump is also scrutinized, and to his great dismay, he seems to be seen among the suspects. The situation escalates when Krump's former partner Elias Maier is wanted by the LKA, and a suitcase with two million euros appears. It's no easy task for Krump and Police Master Hartwig to shed light on the darkness of corruption, grievances, and dangerous solo actions. The fictional plot of the crime novel is based on the real Hessian tax investigator scandal. With a foreword by former tax investigator and SPIEGEL bestselling author Frank Wehrheim.
