Séance on a Wet Afternoon

Myra (Kim Stanley), a self-styled psychic in London, concocts a scheme to gain celebrity. She convinces Billy, her weak-willed husband, to kidnap the young daughter of wealthy parents. She and Billy will demand money, and then she will go to the parents with extra-sensory messages that will help the police find the child and the ransom. The plan unfolds beautifully, except that after her first visit to the parents, the police want to check her out.
