The Psychopath
Inspector Holloway (Patrick Wymark) investigates a series of gruesome murders with one common trait linking them: a tiny doll left next to the victim's corpse. Holloway's investigation ultimately ties the killings to the lost wealth of a German businessman, missing since the end of World War II. Meanwhile, more disturbing clues are uncovered at the home of Mrs. Von Strum (Margaret Johnston), the dolls' owner, and her eccentric son, Mark (John Standing).
