The talented Mr. Varg / Alexander McCall Smith.

The Department of Sensitive Crimes, renowned for taking on the most obscure and irrelevant cases is always prepared to dive into an investigation, no matter how complex. So when the girlfriend of an infamous author who insists her bad-boy beau is being blackmailed approaches Ulf Varg, the department's lead detective, Ulf is determined to help. It's rather difficult to determine what skeletons hide in the hard-living lothario's closet, though. And while Swedes are notoriously tolerant... well, there are limits. Even for the Swedish. The case requires Ulf's total concentration, but he finds himself distracted by his ongoing attraction to his co-worker, Anna, whose own fears about her husband's fidelity are causing a strain on her marriage. When Ulf is also tasked with looking into a group of dealers exporting wolves that seem more canis familiaris than canis lupus, it will require all of his team's investigative instincts and dogged persistence to put these matters to bed.
