Heavy rain pounded against the cracked glass of the window. Blood pooled slowly beneath the lifeless man on the carpet. Detective Vance knelt down to inspect the gruesome crime scene. A silver dagger rested inches away from his cold fingers. Someone had locked the heavy oak door from the inside. No clear escape route existed within this perfectly square room. The dead millionaire wore a sharply tailored black tuxedo tonight. Vance discovered a torn photograph hidden inside the breast pocket. Half of a smiling woman remained visible in the picture. The killer deliberately left this specific message for the police. Lightning flashed outside while thunder shook the entire lonely mansion. Someone extremely dangerous still lurked somewhere within these dark walls. He pulled his revolver and prepared for a tense search.
