At midnight, the manor clock stopped beneath a blood-red moon. Mara Vale found the front door standing open in rain. Inside, all candles burned, but one beside the stairs died. Lord Ashcombe lay facedown beneath his portrait, dressed for dinner. His untouched brandy stood beside a note bearing Mara’s name. She had not visited Ashcombe in seventeen years, until tonight. Then the dead man’s telephone rang upstairs, once, then twice. Mara answered and heard her own voice whisper, “Run now.”
