The Rats in the Walls by H. P. Lovecraft

After restoring his ancestral estate in England, a man begins hearing the sound of rats scurrying within the walls—though no one else can. As he investigates the mystery, he uncovers a horrific secret buried beneath the foundation: a hidden city tied to his family’s gruesome past. The story descends into madness as he confronts ancient evil and inherited guilt. It’s one of Lovecraft’s most disturbing tales, exploring the horror of ancestry and forbidden knowledge. The final revelation is both shocking and unforgettable.
