The rain had finally stopped, leaving the cobblestone streets slick and gleaming like polished obsidian mirrors just outside the tavern. Detective Elara Voss stepped over the threshold, her dark coat swirling silently around her like a cape of impending doom. The victim lay sprawled across the rain-washed stones, a single perfect crimson rose clutched tightly in his cold, lifeless hand. No one had seen anything, the alley emptied in minutes after the fatal shot echoed through the foggy midnight air. Yet, a single white feather rested delicately upon the victim's shoulder, a silent, chilling, dark promise of more to come.
