The storm outside mirrored the turmoil within the grand estate. Sir Reginald lay dead, a bullet hole in his forehead. His glass of brandy sat untouched upon the mahogany desk. The butler’s trembling hand still held the silver serving tray. Everyone claimed to be asleep at the time of shooting. Yet the locked room presented an impossible, puzzling mystery indeed. Detective Aris arrived, his sharp eyes missing no single detail. He noted the position of the body and the window. A single spent cartridge gleamed dully near the cold fireplace. Someone in this house was a murderer, and they lied.
