Midwinter Blood by Mons Kallentoft

Police Inspector Malin Fors is thirty-three and lives with her teenage daughter, Tove, in Linkoping. She and her partner Zeke Martinsson are called out to a gruesome murder scene, where a naked overweight man is hanging from a tree. The victim is revealed to be a man named Bengt Andersson, a loner who was teased by local teenagers and ignored by pretty much everyone else. Malin delves into Bengt's life and finds a traumatic childhood and a connection to a more recent crime. While trying to uncover the truth in the investigation, Malin must also deal with her daughter's raging hormones, a purely physical relationship with a local reporter, and yearnings for her ex-husband, Janne. Midwinter Blood is the first book in the Malin Fors series and would appeal to people who like Helene Tursten and Yrsa Sigurdardottir.
