You may recall from a former Shadow posting for this blog that Walter Gibson, who did the Shadow pulp novels since their beginning, also did scripts for Shadow Comics. He was paid more because of his history with the character. I cannot believe he put a whole lot of thinking into this story, though. The huge skeleton hand is great visually, just not logically.
