The heavy rain washed away the crimson stains that slowly pooled around the motionless body lying on the cold cobblestones. Her pale hand still clutched the silver locket, guarding a secret that someone had killed to keep buried forever tonight. A lone streetlamp flickered above the scene, casting long and dancing shadows that seemed to mock the terrible silence below. Detective Miller stepped out from the darkness, lighting a cigarette while staring down at the victim with weary, sad eyes. He knew this sprawling city was full of ghosts, but he never expected to find his own wife lying there.
