The Killing - David Hewson

Sarah Lund is looking forward to her last day as a detective with the Copenhagen police department before moving to Sweden. But everything changes when nineteen-year-old student, Nanna Birk Larsen, is found raped and brutally murdered in the woods outside the city. Lunds plans to relocate are put on hold as she leads the investigation along with fellow detective Jan Meyer. While Nannas family struggles to cope with their loss, local politician, Troels Hartmann, is in the middle of an election campaign to become the new mayor of Copenhagen. When links between City Hall and the murder suddenly come to light , the case takes an entirely different turn. Over the course of twenty days, suspect upon suspect emerges as violence and political intrigue cast their shadows over the hunt for the killer.
