This was a great episode, based off of a Manly Wade Wellman short story that was featured in Weird Tales back in the '30s. If I remember correctly, the written story was more Lovecraftian, but Rod Serling did a great job transferring it to the boob tube. I read this story in Peter Haining's Weird Tales Anthology As I am aware there are quite a few anthology books. I caught this episode at 430am on the sci fi channel and when it starts I thought something felt pretty familiar (I have seen my fair share of old twilight zone episodes but personally prefer those from the '80s, and happenstance I hadn't seen this episode) Great adaptation of a great story. Check out Haining's anthology if you get a chance, it has a lot of great shorts in it
