The old mansion stood silent beneath a bruised stormy sky. Rain lashed the windows while thunder rolled across the hills. Detective Eleanor Vance stepped into the grand and empty foyer. Her shoes clicked softly on the cold polished marble floor. A single candle flickered on the carved mahogany side table. She paused, listening to the echo of her own breath. The heavy library door stood ajar at the far end. A thin line of golden light spilled across the hallway. She slowly pushed the door open and then froze completely. Lord Rutherford lay sprawled across the room's ornate Persian rug. A silver letter opener protruded from his still lifeless chest. Blood had soaked into the rug's dark and intricate pattern. Eleanor knelt beside the body and checked for a pulse. His skin was cold, his eyes wide open and staring. A shattered brandy glass lay beside the heavy overturned chair. An empty brandy bottle sat beside the overturned mahogany table. The French doors leading outside were securely locked from within. That meant the killer was still somewhere inside the house.
