Detective Miller stood alone in the freezing rain, staring at the dead body lying upon the cold dark wet pavement. The blood on the steps was fresh, painting a grim picture of the violence that occurred there this very night. Yellow tape surrounded the area, fluttering in the wind like a warning flag for those who dared to come closer. The detective knew the killer was watching from somewhere in the dark shadows of the old city alleyway right now. He turned his collar up against the wind and walked away to find the person responsible for this brutal crime.
