Heavy rain washed the dark alley behind the grand theater. Detective Vance stepped over the cold and lifeless human body. Shattered glass glittered brightly beneath his worn leather shoes. A single crimson rose lay upon the victim's chest. The theater manager wept softly into his dirty handkerchief. Nobody heard the fatal shot above the loud storm. Vance realized this twisted puzzle had only just begun.
