The Shunned House

The Shunned House by H. P. Lovecraft Audiobook is a horror fiction novelette by American author H. P. Lovecraft, written on October 16-19, 1924. It was first published in the October 1937 issue of Weird Tales.

Plot:
For many years, the narrator and his uncle, Dr. Elihu Whipple, have nurtured a fascination with an old abandoned house on Benefit Street. Dr. Whipple has made extensive records tracking the mysterious, yet apparently coincidental, sickness and death of many who have lived in the house for over one hundred years. They are also puzzled by the strange weeds growing in the yard, as well as an unexplained foul smell and whitish phosphorescent fungi growing in the cellar.

There, the narrator discovers a strange, yellowish vapour in the basement, which seems to be coupled with a moldy outline of a huddled human form on the floor. The narrator and his uncle decide to spend the night in the house, investigating the possibility of some supernatural force. They set up both cots and chairs in the cellar, arm themselves with military flamethrowers, and outfit a modified Crookes tube in the hopes of destroying any supernatural presence they might find.
When Dr. Whipple naps, he tosses and turns and starts babbling in French until he suddenly awakes. He tells the narrator that he had strange visions of lying in an open pit, inside a house with constantly shifting features, while faces stared down at him. Many of the faces were those of the Harris family, whose members died in the house. When the narrator sleeps, he is awakened by a horrific scream.

He sees a revolting yellowish "corpse-light" bubbling up from the floor, which stares at him with many eyes before vanishing in a wisp through the chimney. He finds his uncle transformed into a monster with "blackened, decaying features" and dripping claws. He turns on the Crookes tube, but seeing that it has no effect, escapes the house through the cellar door as his uncle's body dissolves, transforming into a multitude of faces of those who died in the house as it melts. The narrator returns the next day to find his equipment intact, but no body.

The narrator hatches a plan. He orders a military gas mask, digging tools, and six carboys of sulfuric acid to be delivered to the cellar door of the house. He digs into the earthen floor of the cellar, turning up fungous yellow ooze, and arranges the barrels of acid around the hole in the belief that he will happen upon some kind of monstrous creature.
