The heavy oak door creaked open slowly, revealing a dark room filled with the sharp metallic scent of fresh blood. Detective Miller stepped inside carefully, his flashlight beam cutting through thick shadows to illuminate the lifeless body on the floor. A single silver dagger was buried deeply in the chest of the victim, whose eyes remained wide open in terror. Crimson stains painted the pristine white carpet, forming a gruesome pattern that suggested a violent struggle before the final blow. He knelt beside the unfortunate dead man, noticing a small torn piece of fabric clutched tightly within the cold fingers. The killer had clearly made a terrible mistake by leaving behind such an obvious clue at this very bloody scene. Miller placed the tiny evidence bag into his coat pocket, knowing this mysterious case would keep him awake all night.
