The old mansion loomed darkly under stormy midnight skies. Rain pattered against the cracked, peeling front door’s wooden frame. A lone figure stood shivering, clutching a tattered black umbrella. Footsteps echoed hollowly through the empty, creaking hallway’s depths. The air smelled faintly of damp earth and something metallic. A single candle flickered weakly on the dusty mantelpiece. The victim’s body lay sprawled across the bloodstained rug. Fingers twitched slightly, as if still reaching for help. A half-empty glass of whiskey sat overturned nearby. The killer’s footprints vanished into the shadowed staircase’s curve. Whispers of the past seemed to cling to the walls. A locked door stood ajar, revealing a hidden, bloodied key. The detective arrived just as the first police car’s lights. Shadows stretched long across the floor, framing the crime’s truth.
