Derrick (1974–1998)

This fantastic German 'Krimi' is unique because of its sterile depiction of murder investigation. Derrick's only weapon is his reasoning. He needs no gun to arrest suspects, he fires his arguments one by one at them, so that the murderer (often a neat & rich person) simply has to surrender. The settings are always great: cool, white villas, sleazy nightclubs and, as another commenter said, an absolutely spartan office. As far as I know there are no references to the families and friends of the protagonist and his introvert sidekick Harry, and you need a magnifying glass to find frivolities like humor. The sterility and formality of the series may be repulsive to some viewers, but I think it's a haven for people that are fed up with them Hollywood-influenced police series on steroids.

There are rumors that Derrick is back on Dutch television, so: "Harry, hol' den Wagen!"
