Summary After a night in the castle, romantic notably for Ellen and Heldt, who sneaked out of his shared room, seminar director Kleine alias Baron von Protznitz is missing as 'victim', but actually also in reality, all participants, cook Meisterjahn and Butler Hackforth (both hired actors) finally want to end the game fast. Despite some rivalries, state attorney Sebastian Pringel and commissioners Kathrin Hardt and Erik Schubert applaud Heldt working out the clues to the murder mystery. Kleine is found really stabbed in a storage room. Ellen claims nearest jurisdiction and commissions Heldt to officially investigate the castle, which is locked down as murder site, so nobody can leave. Heldt first finds the impoverished real baron von Protznitz, who noticed an outsider car. While the castle is searched, which proves dangerous with two criminals, an external one as well as a traitor, who ruthlessly traps several people while finding himself in danger. In Bochum Grün and Mario Korthals's parallel research is surprisingly fruitful, which turns out necessary.
