Cold rain lashed against the tall windows of Blackwood Manor. Inside the dim library, the grand mahogany clock chimed midnight. Lord Harrington sat frozen in his favorite leather armchair forever. A silver dagger was buried deeply inside his velvet vest. Crimson blood slowly stained the pristine silk of his shirt. The frightened butler dropped his silver platter onto the floor. Metal crashed loudly against the cold and ancient stone tiles. He stared in absolute horror at the dead man's eyes. A single yellow rose lay ruined upon the bloody floor. Shadows danced wildly across the walls as wind blew inside. The balcony door stood open to the freezing night air.
