"We are met in this cave by the restless sea to reveal the horror in Man's mind. Listen to The Weird Circle!"
This episode, first broadcast on September 5, 1943, adapts Edward Bulwer-Lytton's The House and the Brain, first published in 1859. I've not had a chance to be exposed to the original, so I'll focus on the show itself.
The story starts in London, where our protagonists, Paul and Sandra Whitney, a young couple, are attending an art auction run by their friend, Jim. Paul and Sandra tease each other amicably, and we find a typical mid-20th Century dynamic of a rational, practical husband with his emotional, impulsive wife. They are both fascinated with the occult - he more logically, she more passionately, excited about the details of the macabre. This fascination leads them from a sinister portrait Jim shows them, of an evil old "cutthroat", to his now haunted house, built 450 years ago.
The haunting's physical effects are described as entirely factual - and despite later dismissing claims by Mrs. Browning, the housekeeper, that ghosts swarm the place day and night, they both seem to take the possibility seriously, although Sandra absolutely believes it, while Paul is dubious.
This is a strange, occultism-friendly version of London, where later a policeman is very easily convinced that a ghost was responsible for a murder. Indeed, this contrast between Sandra and Paul isn't like Mulder vs Scully - the true believer vs the skeptic - but instead of two somewhat different attitudes towards an admittedly ultra-mundane world. Sandra is also shown as more susceptible to the hypnotic influences of the antagonist, but Paul still does barely fight it off.
The real horror for them isn't that there is a haunting, or that ghosts are around us, but that there is a malign, mesmeric presence able to control all that is living and dead in the house. That there's supernatural evil specifically alarms them - and leads them to the action which defeats it.
As for sound effects, repeated use of Mrs. Browning's cackle, as well as a children's choir singing a song I couldn't identify, are used to express the presence of horror and the supernatural. There's no repeated reuse of water and wind to connect to the framing seaside story.
Overall, I enjoyed this more than their adaptation of The Fall of the House of Usher, and the dynamics between Sandra and Paul really manage to drive the story along and expose us to this weird London.
I'm looking forward to reading Bulwer-Lytton's original and comparing notes some day.
