Cold fog rolled over the silent, dark, empty Victorian manor. Inspector Vance stepped through the heavy, shattered front door carefully. Moonlight revealed a pool of thick crimson liquid upon marble. Lord Blackwood lay dead beside his overturned mahogany study chair. A gleaming silver letter opener pierced his expensive silk tie. Clutched in his cold right hand was a torn photograph. The grandfather clock struck midnight with a dull, heavy chime. Someone chuckled softly from deep inside the dark hallway shadow. Vance pulled his heavy pistol quickly from his coat pocket. The killer was still waiting inside this dark, quiet room.
