The flickering neon sign cast a sickly green glow across the street. Rain pelted the grimy window of the rundown apartment building relentlessly. Detective Harding sighed, running a tired hand through his already disheveled hair. Another late night call, a familiar and unwelcome disturbance had arrived. He pulled his trench coat tighter against the biting November chill. The dispatcher’s voice had been clipped, filled with a grim urgency. Someone discovered a body inside the old abandoned factory just now. Harding knew the place, a notorious haunt for local teenage vandals. He parked his unmarked sedan beside several flashing patrol car lights. Uniformed officers guarded the perimeter, keeping curious onlookers safely away. The crime scene tape shimmered, a stark yellow warning barrier. A rookie officer saluted him, mouth tight with nervous tension. "Inside, sir. It’s not a pretty sight at all," she warned. Harding’s boots crunched on fragments of broken glass and debris. The air hung heavy with the smell of stale damp concrete now. A single bare bulb illuminated the grim discovery unevenly. A woman lay sprawled, her crimson dress a shocking contrast against grimy floor. Her wide, unseeing eyes stared blankly toward the blackened ceiling. No obvious weapon lay nearby, no signs of struggling were evident. Only a meticulously placed white orchid rested upon her pale chest.
