Think of them as podcasts from decades ago: Horror masters like Stephen King have pointed to the rich imagination of radio shows as offering more appropriate terror than the page or screen. In the era before television (just imagine), purely audio suspense was provided by not only by the writers, actors, and the listeners’ own imaginations, but the sound-effects engineers, in an art form that has now been lost to the ages. Gruesome shows like
Inner Sanctum and
Lights Out!helpfully provided health precautions with their intros for faint-hearted listeners. But the era’s premiere radio drama,
Suspense, also offered lots of scary moments for the thrill-bound, as did the more adventure-based
Escape and the sci-fi-themed
X Minus One. Then the sound-effects guys would go to town, cracking walnuts to indicate bones and using ripe melons to depict bodies falling from buildings: the squishier the better. For Halloween this year, try one of our selections below, with mournful organ chords, creaky doors, and various screams by some names you’ll recognize, as many film stars flocked to the popular radio medium in an attempt to get further exposure. That’s only if you dare, of course.
1. Suspense, “The House On Cypress Canyon”
2. Lights Out!, “Cat Wife”
3. Escape, “Three Skeleton Key”
4. Suspense, “Ghost Hunt”
5. Lights Out!,“Murder Castle”
6. Inner Sanctum, “Black Seagull”
