At midnight, the manor clock struck thirteen, waking every guest. Lady Vale lay beneath the staircase, her gloved hand raised. Rain stitched thin silver threads across the darkened ballroom windows. Inspector Marlowe arrived carrying no umbrella and one question only. Who had locked all the doors before the storm began? Nobody answered, though twelve faces turned toward the portrait above. Then the dead woman's watch chimed from inside Marlowe's coat.
