We were watching the second episode of Guillerimo del Toros cabinet of curiosities when I realized I was familiar with the story it was based on. The Graveyard Rats is a short story by Henry Kuttner but I was pretty sure I hadn't read the original story. I suspected it was a comic book adaptation and that evening I managed to track it down.
The story (included below) was drawn by Jack Cole an artist with a promising career who committed suicide for mysterious reasons. Neither adaptation follows the short story which you can read in it's entirety here.
