The grand mansion loomed under a stormy, moonless night sky. Detective Cole adjusted his coat, feeling the cold wind bite. A single candle flickered in the hallway, casting long shadows. The butler stood stiffly, his face pale with obvious dread. Footsteps echoed down the marble staircase, slow and deliberate. A scream pierced the silence, then abruptly cut off short. Cole rushed toward the sound, heart pounding in his chest. The study door creaked open, revealing a gruesome, bloody scene. Sir Reginald lay sprawled across his desk, eyes wide open. A silver letter opener protruded from his lifeless, motionless chest.
