The relentless cold rain lashed against the ancient fractured windows of the dark, crumbling old stone manor on the hill. Inside the pitch-black room, a single candle flickered faintly, casting long dancing shadows across the dusty floorboards near the door. A body lay motionless on the floor, a knife handle protruding from its back, pooling blood near the overturned chair. The only sign of struggle was a single broken vase by the fireplace, its shards scattered on the stone hearth. A heavy oak door creaked open slowly, and Inspector Hayes stepped into the room, his eyes scanning the scene calmly. On the polished marble mantelpiece, a single white glove lay neatly folded, looking out of place among the crime scene. A single muddy footprint on the rug led directly from window to the body and disappeared near an open door. Inspector Hayes knelt by the body, examining the muddy footprint with a critical eye, knowing the killer left incriminating evidence.
