Rain lashed the manor windows. Lightning split the ancient oak. A scream tore through silence. Footsteps echoed down the hallway. The library door stood ajar. Candlelight flickered on crimson stains. A body slumped over mahogany. The silver dagger gleamed coldly. No one else was present. Yet the clock kept ticking.
