Rain rattled the manor windows. Inspector Hale arrived before dawn. The gate hung half-open, sighing. Servants whispered behind drawn curtains. A scream had ended supper. Now silence held its breath. In the library, candles guttered. Lord Ashford lay face-down, dead. His ringed hand gripped ash. No footprints crossed the rug. Only a torn letter remained. Hale read it, frowning hard. Someone knew tonight's secret well. Outside, thunder covered new footsteps.
