The first case: the small matter of a man stabbed in the back of the knee. Who would perpetrate such a crime and why? Next: a young woman's imaginary boyfriend goes missing. But how on earth do you search for someone who doesn't exist? And in the final investigation: eerie secrets that are revealed under a full moon may not seem so supernatural in the light of day. No case is too unusual, too complicated, or too, well insignificant for this squad to solve. The team: Ulf 'the Wolf" Varg, the top dog, thoughtful and diligent; Anna Bengsdotter, who's in love with Varg's car (and possibly Varg too); Carl Holgersson, who likes nothing more than filling out paperwork; and Erik Nykvist, who is deeply committed to fly fishing.
