The heavy rain fell hard upon the dark cobblestone streets, slowly washing away every single trace of brutal midnight murder. Detective Miller stepped carefully over the bright yellow police tape, his tired eyes scanning the grim alleyway for hidden clues. A silver pocket watch lay broken near the pale victim, its frozen hands pointing toward the exact moment of death. Dark blood stained the damp brick wall behind him, forming strange symbols that nobody could ever truly begin to understand. He pulled his wool collar tight against the bitter wind, knowing this dark case would haunt him until his death. Somewhere in the deep shadows, the killer watched silently, waiting for the next move in their deadly cat and mouse.
