Rain hammered Blackthorn Manor's windows. At midnight, the screaming stopped. Inspector Vale arrived moments later. The butler answered without speaking. Blood stained his white gloves. Upstairs, Lord Blackthorn lay smiling. A dagger pierced his heart. His bedroom door stood locked. The windows were nailed shut. Four relatives waited downstairs, trembling. Each carried an identical telegram. Vale unfolded the nearest message. The message predicted this murder. Tomorrow's date appeared beneath it. The handwriting belonged to Vale.
