The Swedish criminal legal system has a place for even the most complex and strange cases, for which the Malmö police are responsible for an elite unit known as the Sensitive Investigations Unit: Ulf “Wolf” Varg, an attentive and thoughtful leader, Anna Bengsdotter, in love with Varg’s car (it is possible that Varg himself too), Karl Holgersson, who loves filling out paperwork more than anything in the world, and Erik Nykvist, who is wholeheartedly devoted to the art of fishing. Ulf takes on the most unusual crimes, requiring tact and a good knowledge of human nature, along the way trying to unravel the tangle of his own romantic feelings and help his dog, the only dog in all of Sweden who has learned to read lips, cope with depression.
