From Casual Debris.
Published 32 years ago this month, the Ellery Queen novella "The Lamp of God" is technically a supernatural story. The premise finds Detective Ellery Queen invited by lawyer acquaintance Thorne to help escort a young woman, Alice, to her father's isolated house to retrieve her inheritance. Arriving at the isolated Victorian "Black House," they spend the night in the adjacent "White House" where the deceased man's remaining kin have settled. Upon waking the next morning, the black house has entirely vanished!
Though readers can deduce early on that a rational explanation will be available to explain the house's disappearance, the fact that the plot hinges on the possibility of a ghostly house categorizes the story as supernatural. In fact the story can potentially be categorized as a ghost story, if one were to be inclined to argue that vanishing house is a ghostly object, but since the plot does not reflect it being an apparition, only that it disappeared, I would refute the claim. The story was, however, originally titled "The House of Haunts," whether by the authors or publisher, but despite this detail the supernatural element is not directly investigated, nor speculated upon, so nothing in the text claims that a haunting is a possibility.
It is only at the story's denouement that the supernatural element is entirely and indisputably removed.
Though it appears that by employing the supernatural as a possibility, the authors are challenging their own conventions, along with challenging the conventions of early detective fiction. However, they are taking safe refuge with how the supernatural element is presented. The story opens with a brief segment that establishes Ellery Queen as a strictly rational man, so that no fanciful ideas can act as potential realities in his mind. When the house disappears Queen is flabbergasted, as are the other, more impressionable, witnesses. Though Queen does, on occasion, comment on the fact that God's world is shaken and there are some minor comments on his faith in the rational being challenged, his thoughts are kept conveniently away from the reader and we later discover, though it is obvious, that throughout the plot his rational brain is picking up clues and piecing the evidence together. The questioning of Queen's reality is simplistic and certainly not terribly existential; Thorne and Alice are the ones whose cores are affected, but they are secondary players in the plot so their realities are further removed. Because even much of Queen's portrayal is distanced, and though we might receive the glimpse of a thought along the lines of his worlds being shaken up, his investigative mind is kept wholly secret, so that we are left to wonder what in fact was spinning in that head of his.
As a mystery story it is a product of its time. It features stock characters and is high on melodrama. However, it is quite entertaining, and the explanation of the house's disappearance is a good one. Some might figure it out; I admit that I did not.
