Cold rain washed the dark blood down the cobblestone street. Inspector Vance stared quietly at the lifeless body before him. A silver pocket watch still ticked inside his bloody coat. The victim held a tiny golden key in his palm. Moonlight revealed a shadowy figure lurking near the old alley. Vance pulled his heavy pistol and shouted into the gloom. Nobody answered his stern call except for the howling wind. The killer had already vanished into the thick fog tonight.
