Rain battered Blackthorn Manor as midnight swallowed the coastal road. Detective Clara Voss arrived carrying flowers instead of her revolver. Her invitation promised dinner, reconciliation, and an announcement concerning inheritance. The scream reached her before she could touch the knocker. Inside, seven guests stood motionless beneath the chandelier's trembling light. Lord Blackthorn lay across his desk, smiling through bloody teeth. A silver letter opener protruded neatly from his velvet waistcoat. Beside his hand, an untouched wineglass held one white feather. "Nobody touched him," whispered the butler, carefully avoiding Clara's eyes. Clara noticed mud beneath his cuffs, though his shoes gleamed. Then the grandfather clock struck thirteen, silencing every nervous breath. From upstairs came Blackthorn's voice, calling Clara softly by name.
