Horst Grossman is a doctor who lives in Pforzheim, Germany. He is considered to be a model citizen and is known for his excellent herbal blend tea.
Behind the mask of the kind doctor, he is one of Johan's loyal followers. Known by the Baden-Württemberg state police as "The Dissector," he successfully killed twenty eight people (two of which were part of the middle-aged couple serial killings throughout Germany) and left absolutely no evidence. Johan kills him shortly before heading to Ruhenheim.
