The rain fell hard against the pavement, washing away the grime but failing to cleanse the sins of this city. Detective Miller stood over the cold body, staring down at the red pool slowly spreading across the wet gray concrete. The man’s eyes were wide open, frozen in a look of terror that suggested he knew his killer very well. A single silver cufflink lay near his hand, glinting under the streetlights that flickered continuously above the dark alley entrance. Miller pulled his collar tight against the wind, knowing deeply that tonight marked the start of a very long game. He sighed heavily before turning to the uniformed officer, who looked too young and too pale for this brutal work.
