The storm arrived before midnight, carrying secrets across Blackwater Bay. Inside Harrow House, thirteen guests watched their hostess extinguish candles. Lady Harrow smiled, though her trembling hands betrayed unfamiliar fear. “Before we dine, someone must confess what happened last winter.” Nobody answered, but the grandfather clock abruptly stopped its ticking. Then darkness swallowed the room, and something heavy struck marble. When lightning illuminated the windows, Lady Harrow lay unnaturally still. A silver letter opener protruded neatly beneath her pearl necklace. Detective Rowan noticed the blood before anyone began to scream. It pooled around her fingers, spelling one impossible, familiar name. His own, written exactly as his mother once wrote it. She had been dead for thirty years, buried without hands.
