Isabell Kreitz's graphic novel "Haarmann" tells the story of "Fritz" Haarmann, a German serial killer born October 25, 1879. From 1918 to 1924 Haarmann killed 24 young men and finally got caught and convicted in 1925. The graphic novel documents this episode in his life and a German post World War I society in a compelling black and white style, starting with his first known victim: Friedel Rothe a 17-year-old youth who disappeared in September 1918. It also depicts his homosexual relationship with Hans Grans and several rumors that until today have remained vivid: For example the possibility that Haarmann was selling the victims’ meat as canned black market pork. Although this could never be proven the extreme poverty and social problems of the time as well as the subtle horror of this thought seem to keep speculations alive. Even today Haarmann is known as "the Butcher" or "the Vampire" of Hanover. He killed his victims by biting through their throats and dismembered them completely before getting rid of the bodies. Afterwards he or his lover sold their belongings on the black market. He was guillotined on April 15, 1925. Isabell Kreitz isn’t the first artist to become "inspired" by this gruesome case: Many films used the case as a storyline or to integrate the topic of how to treat dangerous or maybe even psychotic criminals, one being the famous classic "M" directed by Fritz Lang in 1931. Like this film, Kreitz’s graphic novel is not just the portrait of a serial killer, but also of a society that is as defective as it is hungry for spectacular detail. In the end it leaves it’s readers at a loss: Even though the case seems very clear you still can’t figure out the most important question: "Why?".
