Architektur eines Todes.

Sofia Martens, star architect and owner of a large architecture office, asks her old friend, public prosecutor Scheer, for help: her assistant Anett Berger has disappeared. Scheer draws Charlotte Sänger and Fritz Dellwo's attention to the case, but they are not exactly enthusiastic about it as the search for missing persons is not one of their duties. At first, they are reluctant to investigate the disappearance of Anett, but they are increasingly fascinated by this completely different world of Sofia Martens.
