Ann Todd, Patrick Magee and Tony Beckley star in this ghoulish 1972 mystery directed by thrill-meister Robert Hartford-Davis. Murder is sinful, but apparently not for a religious zealot who thinks he's serving his holy master by preying on young women and offering them up for sacrifice -- all in the name of piety gone mad. The killer has the city quaking under siege, worried about its female denizens. Can he be stopped?
