He's got no style, no flash and he's middle-aged. But Swedish detective Martin Beck is good at one thing: methodically catching criminals so they can be put away for a long time. His tightly-wound partner, Gunvald, is the opposite: an impulsive man who cuts a dashing figure, is in no way politically-correct and who never met a boundary he didn't leap to cross. He'll do anything to get information from a suspect, including enhanced interrogation techniques. It's classic good cop/bad cop, and together with their team they bring down dangerous criminals lurking in the seedy Stockholm underworld. Beck may be a loner but he's not anti-social; he regularly sees his daughter, with whom he has a much better relationship than when he was neglecting her growing up. And at the end of a workday, there's always an interesting conversation and a nightcap with a neighbor who gives new meaning to the word quirky.
