New investigations by Commissioner Schenck

The peace of the peaceful and wealthy city of Zurich in the middle of the 20th century was again broken by a bloody orgy of murders of young girls. Maniac? Yes, not one? Commissioner Shenk''s shock brigade again has neither rest nor peace. But they must stop the series of brutal killings (Knights of Darkness). When the talent goes to a fanatically religious person with an unhealthy psyche, and even obsessed with the dream of world recognition, this can end in a terrible tragedy ("Painting blood on the wall").The previous investigations of Commissioner Shenk and his loyal assistants Franz Fischer, Ignaz Mayer and Mateusz Glinsky can be found in the second part of the book "Swabian stories".
