Der Ermittler is a German television series set in Hamburg, featuring a team of investigators led by Chief Inspector Paul Zorn.
His colleague Eva Klaussner and their superior, Director of Criminal Investigation Henning Peters from the Hamburg homicide squad, were also part of the team.
In the 2004 season, forensic pathologist Dr. Tina Jaeger and trainee detective inspector Tim Rasch joined the group.
Writers of the individual episodes received contributions from authors including Eva and Volker A. Zahn, Johannes Dräxler, Remy Eyssen, and Eva and Horst Kummeth.
To ensure a diverse range of perspectives, various directors were involved in the creation of different episodes.
