I want to identify a short story that inspired a Hellboy tale. The story Double Feature of Evil, by Mike Mignola (drawn by Richard Corben) features the short stories "Sullivan's Reward" and "The House of Sebek". Mignola says about Sullivan's Reward that it:
[...] owes a lot to a very strange short story by Belgian writer Jean Ray (1887-1964)-at least I think it does.
He claims not to remember the name of the story, but Mignola claims that he is positive the story is from Jean Ray.
In this story Hellboy meets a guy called Sullivan, who confesses to being a murderer. The thing is that he hasn't killed anyone; it is his house who does it.
Sullivan explains that due to his addiction to alcohol he lost everything (family, job, etc.) until one day a stranger who looked like a lawyer gives him the keys to a house and a lot of legal papers. When he visits this house he finds a skeleton in one of the rooms and then suddenly three gold coins fall from downstairs, despite the guy is alone in the house. He buries the skeleton in the back yard.
After receiving the legal papers Sullivan loses interest in alcohol, but the first night sleeping at the house he has strange dreams, the craving comes back and he starts
luring homeless people, shambling drunks and prostitues into the room where he found the skeleton. Each time one is locked in that room he receives three gold coins and the next morning a skeleton is all that is left from them in the room.
In this tale there is also an ominous picture of an old man, of whom Sullivan says
"I've gotten it into my head that he built this house and that he came by his money in some bad way."
At the end of the story Sullivan
locks Hellboy in the room. When he asks for his payment a massive pile of gold coins crushes Sullivan.
I have been trying to find the original story, but despite some of Jean Ray's stories having old houses as important elements of the story (Malpertius, Maison à Vendre ["House for Sale"], etc.) not many details match the
man-eating house that rewards the owner with three gold coins per victim element.
Since this Hellboy tale is just inspired by Jean Ray's, the original may or may not contain all of these elements. Mignola definitely gave it his touch. Or maybe I'm not conducting my research properly.
I would appreciate any help identifying the original Jean Ray story.
