Apprentice Yannik Rösner and supervising employee Karsten Kleinert discover in the stock shed the skull-smashed corpse of boss Stefan Stuckenthaler, who returned unexpectedly from his many Alpine prospecting trips to select perfect trees to cut up into perfect wood for musical instrument builders.

Theresa had an affair with Karsten, who also knew about a major client complaining recently about business fraud.
