The Gorman here would be John Gorman, one of John’s old army buddies, who collaborated on at least one magazine piece (“The Cobra Had Me Cornered,” Cavalier, May 1955).
After the publication of Jadoo, John (Keel, that is) struggled with writer’s block. As he recalled in a piece for Writer’s Digest (August 1959), “Finally, I decided a change of environment might help. I got rid of my pet snakes and moved to another, larger, brighter apartment and picked a gregarious army buddy for a roommate. We had parties every night and life was a million laughs and I was just too busy to think about writing anymore.”
Eventually, of course, he got back to work. Meanwhile, the world needed to know there were a couple of available bachelors on the loose.
