Yet another post about invisibility in fiction! Will I ever run out of these? I feel like I need to write another book just about invisibility fiction.

So in my last post, I wrote about “Invisible Death”, which appeared in the January 1930 issue of Astounding Stories of Super-Science. On a whim, I happened to browse the rest of the stories, and found another story about invisibility in that same issue. Clearly invisibility was a hot topic in that era.

The new story I found is titled “The Cave of Horror,” by Captain S.P. Meek.

It is a mixture of horror, action, and science fiction, and features run-ins with an invisible monster that has wandered up from the bowels of the earth and is now haunting Mammoth Cave, in Kentucky!
