Rain hammered Blackthorn Manor’s windows as midnight silenced the clocks. Detective Mara Voss arrived carrying questions nobody wished answered tonight. Inside the library, Lord Ashcombe lay beneath a shattered portrait. His right hand clutched one black feather, slick with blood. Every door remained locked, and every guest denied entering alone. Yet muddy footprints crossed the carpet toward the blazing fireplace. Mara counted seven guests but discovered eight untouched champagne glasses. Then somewhere upstairs, a woman laughed, and the lights died.
