The storm arrived at midnight. Rain hammered the old manor. Inside, candles flickered and died. Lady Ashworth lay quite still. Her tea had gone cold. Poison traced her pale lips. Detective Marsh reached the gates. Constable Reeves waited there, trembling. "The household heard no screams." "Who found the poor woman?" "The butler, sir, at dawn." Marsh studied the iron door. No locks were forced open. The killer walked right in. Footprints ended beside her chair. "Someone here knows too much." Thunder rolled across the hills. The game had just begun.
