Milchgeld. Ein Kluftingerkrimi (2012)

Detective Kluftinger is investigating the murder of an employee of the local dairy plant. While this provides a welcome excuse not to go on a sunny Mediterranean holiday with his wife, he finds that many locals, including his own father, are doing their best to obstruct his investigations. Kluftinger himself is uncomfortable investigating local dairy farmers and their affairs, but he keeps going and eventually discovers a huge scandal.
