(1966, Upgraded 10/30/21) Gunther Stoll, Pinkas Braun, Monika Peitsch. Terrifying things are happening around the grounds of an old castle, within which is a boarding house for delinquent girls. Things get nutty when some of the girls die mysteriously. A hunchback killer is on the loose! Scotland Yard is called. More murders occur, the screams of the victims being silenced by the sound of a church organ. Good creepy fun and one of the best color Edgar Wallace chillers. Beautiful Color, from 35mm.
