Heavy rain battered the window. Blood pooled on the floor. Detective Vance surveyed the room. A cold wind blew inside. The victim lay completely still. Pale moonlight revealed her face. Broken glass surrounded the doorway. Someone had entered very quietly. Muddy tracks stained the carpet. Footprints trailed toward the hallway. A silver knife rested nearby. The killer left in haste. Silence filled the dark mansion. The tall clock ticked loudly. Vance knelt beside the corpse. She clutched a torn photo. He gently took the evidence. The picture showed three people. One face was scratched out. A deadly game had begun.
