The rain fell hard against the cold pavement, washing away the sins of the city but leaving the blood behind. A single streetlamp flickered above the prone body, casting long and twisted shadows that danced upon the pale, lifeless face. Detective Miller pulled his collar up tight against the chill wind, staring down at the shattered remains of the man. A silver watch lay broken near the outstretched hand, its hands frozen in time at exactly three in the morning. Silence hung heavy in the damp air, broken only by the distant wail of a police siren approaching the scene.
