This episode marks the only known instance in which future Oscar-winner Jodie Foster shared screen time (after a fashion) with Twilight Zone creator Rod Serling!. The ten-year-old Foster is cast as Pip Baker, the daughter of Chief Ironside's friends Gerald and Carol Barker (Paul Carr, Anne Whitfield). Morbidly fascinated with witchcraft and the occult, little Pip is convinced that she has cast a spell upon her parents' nasty landlord, causing the man's death. Later on, however, the police arrest a mentally challenged adult named Billy (Lee Paul) for the murder. Certain that neither Pip nor Billy is the guilty party, Ironside launches his own investigation, which at one point brings him in contact with a certain Mr. Thyros (Serling!), the black-clad owner of a "Witches'" store.
