One of the more prolific contributors to the spicy pulps was Hugh Cave, who contributed numerous tales under the name Justin Case.  Much of Cave's fiction has been reprinted, including a collection of his weird menace stories entitled THE CORPSE MAKER.  Edited by Sheldon Jaffery and published by Starmont House in 1988, THE CORPSE MAKER collects seven of Cave's weird menace stories, including "The Thing from the Swamp" from the February 1942 issue of SPICY MYSTERY STORIES.
