It's so creepy. This character is so depraved he's compelling. His downfall is created from being betrayed by his wife's (love). How deep is love? Better still, how deep and firm is Martin's character before being boosted by this love? Not too concrete it seems. His wife cheats on him. He utterly falls apart. Sure, it's the stuff songs are made of, but Martin reacts beyond lamenting and crooning. The young couple in the cave begin by professing love. What happens when this love is severly tested? Cannabalism is the rule of the day after torment settles in. Seems our young man, George, is vulnerable as well. It is a hard call as we are not entrapped and starving. Cannabalism is a documented human option with starvation. Is George depraved in the "evil" way Martin seems to be. Is Martin evil, or just terribly disturbed and ruined? It's another tale of destroyed humanity via suffering...I do tend to choose these lovelies....Still, I think this episode offers even more. It is strange and this strange quality comes across very well with the radio medium. This is evident with the "voices" in the cave. These are only voices, surely, but we the listeners certainly feel for them. We are not the only people listening, for Martin is listening too. Unlike us, he listens, is fascinated as we are but leaves them in there. The Psychiatrist, like us, is startled and compelled. Are we compelled because we identify to some degree? It boils down to possibilities. This is a fantastic tale, and unlikely, though likely enough to convey a good deal of palpable horror.
