The heavy oak door swung open without a single uttered sound. Candles flickered wildly across the table, casting restless, dancing shadow shapes. A dinner party once held laughter, now frozen in dreadful silence. Eight chairs stood precisely placed, yet one gaped empty and still. Lord Ashworth’s velvet seat held a body, pale and terribly limp. His crystal goblet was shattered, staining the white linen deep red. No guest had heard a cry, a plea, or final breath. Inspector Hale arrived with rain clinging to his long grey coat. He scanned the shocked faces slowly, reading their practiced, guarded masks. Only the grandfather clock ticked on, counting the seconds of life.
