The cold rain fell hard against the pavement while the detective looked down at the body lying in the street. A single drop of crimson blood stained the white collar of the expensive shirt worn by the unfortunate victim tonight. Detective Miller lit a cigarette and watched the gray smoke curl slowly up into the dark and stormy night air. There was no gun to be found near the crime scene, making this case particularly difficult for him to analyze. Somewhere in the deep shadows of the alleyway, a watching figure smiled silently before turning to walk away very quickly.
