Thunder rattled the old Ashworth manor as the storm drenched the empty ballroom, and a chilling scream echoed ominously still. The stoic butler, Sir Reginald, entered the library, discovering Sir Harold slumped over the mahogany desk, eyes frozen in terror. A single candle flickered beside a bloodstained letter, its seal broken, revealing a cryptic confession written in trembling, ink‑stained hand. Detective Mara Sinclair, draped in a black trench coat, slipped silently through the rain‑slicked doorway, eyes scanning the darkened hallway. A murmur of footsteps echoed from the attic, hinting that the murderer might still be lurking within these cursed walls.
