The Picture in the House by H. P. Lovecraft

While seeking shelter from a storm, a traveler enters a decaying rural house and meets an unnerving old man with a disturbing interest in a book of anatomical drawings. As the story unfolds, the setting grows more ominous, and the final revelation is chilling. This compact horror tale plays on isolation, decay, and the grotesque. Lovecraft turns a quiet countryside visit into a brush with something ancient and horrifying.
