Heavy rain lashed against the cracked windowpanes of Blackwood Manor, obscuring the terrifying scene that lay silently inside the library. Lord Reginald sat slouched in his velvet armchair, a golden letter opener buried deep within his cold, motionless chest. Crimson blood seeped slowly into his crisp white shirt, dripping onto the intricate Persian rug beneath his polished shoes. A half-empty glass of amber whiskey rested upon the mahogany desk beside an unfinished letter written in hurried cursive. The grandfather clock chimed loudly in the hallway, marking midnight just as a sudden shadow flickered past the doorway. Detective Miller stepped carefully over the threshold, his wet trenchcoat dripping rainwater onto the pristine hardwood floor below him. He pulled off his leather gloves, kneeling beside the corpse to inspect the bizarre symbols carved into the desk. Outside, thunder roared fiercely across the darkened estate, sealing the grand house from the rest of the cold world.
