Rain hammered the cobblestone streets. Detective Harlow lit another cigarette. The body lay face down. Blood pooled beneath the streetlamp. A woman screamed from above. Harlow glanced up, eyes narrowed. Curtains fluttered in an window. Someone had witnessed the crime. He approached the corpse slowly. The victim wore expensive shoes. A gold watch remained intact. This wasn't a simple robbery. Harlow knelt beside the man. Something glinted in his palm. A small, bloodstained silver key. The killer missed this clue. Harlow pocketed it very carefully. Footsteps echoed from the alley. He reached for his pistol. The game had just begun.
