The heavy rain hammered against the windows of Blackwood Manor. Inside, a lone candle flickered in the darkened study room. A lifeless body lay sprawled across the expensive Persian rug. The victim was Lord Ashworth, a man of many secrets. His cold gray eyes stared at nothing, forever frozen now. A gleaming silver letter opener protruded from his chest area. The ancient grandfather clock struck midnight, echoing through empty halls. Somewhere upstairs, a wooden floorboard creaked beneath an unseen weight. Detective Sarah Chen arrived at the manor just after three. She immediately noticed the broken lock on the garden door. Someone had entered the manor without forcing any windows open. The killer knew this grand house intimately, she thought grimly. Six prominent guests had gathered here for the weekend party. Now one of them was most certainly the ruthless murderer. The terrible storm had cut them off from the world. No phone lines worked, and the roads were all flooded. They were trapped here together with a killer among them. Sarah slowly pulled out her notebook and began taking notes. The dangerous game had only just begun, she thought silently. Outside, the fierce storm raged like some hungry wild beast. Lightning flashed, briefly illuminating the terrified faces peering from above. The frightened guests gathered on the staircase, watching her work. Every single guest had a motive, she realized with dread. The young widow stood closest, her hands trembling very visibly. The angry partner scowled, arms crossed tightly over his chest. The timid secretary stared fixedly down at the floor instead. One of these people had plunged that sharp knife deep. Sarah slowly closed her notebook and looked up at them. "Nobody leaves this house tonight," she announced with quiet authority. The storm howled its approval through the old stone walls.
