Detective Vance stared down at the lifeless body lying coldly upon the damp and forgotten autumn leaves. Shattered glass glittered under the harsh streetlamp while heavy rain began washing away crucial microscopic evidence. A silver pocket watch ticked frantically inside the victim's torn pocket, mocking the investigation team completely. Shadows danced across the gothic mansion gates as whispering neighbors gathered behind the yellow police warning tape.
