Rain hammered the manor windows. Midnight swallowed the gravel drive. Inspector Vale stepped inside quietly. Candles guttered along dark corridors. Guests whispered behind velvet curtains. A violin stopped abruptly upstairs. The butler's hands trembled visibly. He pointed toward locked library. Vale smelled iron and smoke. Books lay scattered like birds. Lady Harrow slumped beside desk. Her throat wore crimson lace. A teacup steamed, untouched nearby. Someone had stirred sugar twice. Footprints dried near the hearth. Only one print faced outward. Vale noted the missing key. Thunder hid a distant laugh.
