It’s another week of catching up on our Listener Library! This time, thanks to a recommendation from Holly, we are listening to “The Thing in the Cave,” from CBS Radio Mystery Theater. A group of speleologists find themselves trapped in a cave reputed to be inhabited by a monstrous creature. Can they overcome their own shortcomings to survive? Is there really a monster that dwells in this subterranean world? Is proper letter-writing etiquette really that important? Listen for yourself and find out!
