I'm finally returning to Arch Oboler's Lights Out, this time with "Little Old Lady" from November 17, 1937. A young lady brings her friend out to the woods to see her aunt. The aunt just might be the quintessential crazy old cat lady... or the most sinister old woman who ever lived. Unlike the more reserved Inner Sanctum, you could always count on Lights Out to delve head first into something utterly weird; such is the case here.
