The series is inextricably linked with its main actor, Klaus Löwitsch. He was specialized in rough, gnarled loner types for decades. And so it is in this TV series. The private detective stories are set against the backdrop of the Duisburg inland ports. And so the main character drives in a small motorboat with a typical bobble hat and with his usual grim expression through the harbor to clear up his cases. Of the German detective series of the time, it is one of the best.
