The rain beat against the heavy glass windows while the old clock chimed midnight in the silent, dusty drawing room. Lord Blackwood lay sprawled across the Persian rug with a silver letter opener buried deep inside his cold, pale chest. Inspector Reed stepped over the bloodstained carpet, his sharp eyes scanning the locked door and the shattered crystal wine glass. A single gold cufflink glimmered on the floor, hinting that the killer had left a small trace behind them now. Outside the room, the frightened guests whispered in hushed tones, knowing that one of them was a cold murderer tonight.
