Rain hammered Blackthorn Manor as midnight swallowed the surrounding hills. Inside, thirteen guests waited beneath chandeliers that flickered without wind. The hostess had vanished shortly after proposing her final toast. Nobody mentioned the scream until somebody noticed the locked library. Detective Mara Vale arrived carrying wet gloves and unwelcome questions. She found Lord Blackthorn sprawled across his desk, smiling faintly. His throat was cut, but his immaculate collar remained white. Beside him lay a chessboard missing every single black piece. Someone had arranged the white queen inside his open mouth. The library windows were bolted, and only one key existed. Mara lifted that key from the dead man's clenched fist. Behind her, the missing hostess appeared, wearing somebody else's blood. “Before you ask,” she whispered, “my husband died yesterday morning.”
