Moritz Eisner’s first assignment as a member of a new special commission within the Ministry of the Interior—tasked with handling specialized criminological cases throughout Austria—takes him to the Arndorf Monastery in Carinthia. An international organ competition is taking place there, and a very special member of the jury is scheduled to receive personal protection. When the arrival of the Bishop—who was scheduled to open the competition—is delayed, the young organist Nikolaus Kutil steps in to fill the void. However, the spectacular opening concert ends in catastrophe: an organ pipe breaks loose from its mountings and crushes the young man to death in front of the assembled audience. Moritz Eisner and his new superior, Section Chief Schremser, are on the scene.

Strike at the Ostendorf shipyard in Kiel: Works council spokesman Bruhns wants to agree to the dismissal of a maximum of 50 men in order to ensure the preservation of the Kiel shipyard. The boss of the shipyard, Felix Ostendorf, tries almost desperately to make it clear to him that that won't be enough. But Bruhns remains firm, because he gains much personal advantage from his control over who is allowed to work. When Commissioner Borowski is called to the shipyard the next morning, Bruhns lies dead on a work raft.

Environmental activist Hermann Wegschneider—who had been a thorn in the side of many in the village due to his bitter struggle against the industrial exploitation of a local healing spring—has been found dead at the spring itself.

The carefully draped corpse of 16-year-old student and talented pianist Rita Koehler is found on a grand piano in a concert hall, her body apparently embalmed. Could it have been assisted suicide? The body of an old man, also prepared, is then found - Karl Hahnemann, born in 1923. What did Rita and Hahnemann have in common? Both had a talent: Rita in music, Hahnemann a gifted chess player. A third victim makes it inevitably clear to the investigators that they are dealing with a serial offender: when the seven-year-old, highly talented Björn disappears, Borowski, his colleague Alim Zainalow, and police psychologist Frieda Jung urgently need to decode a pattern in order to track down the perpetrator.
