The storm raged outside relentlessly. Inspector Vale stared at shadows. Then the telephone loudly rang. "Come to the old mansion." "Lord Ashworth has been murdered." Vale's heart quickened with dread. He grabbed his heavy raincoat. The drive took an hour. Ashworth Manor loomed through fog. A butler opened the door. His face was terribly pale. "Upstairs, sir, in the library." Vale climbed the marble staircase. The library door stood ajar. Inside, chaos met his eyes. Books were strewn across floors. Lord Ashworth slumped over desk. A dagger pierced his back. Blood dripped onto Persian rugs. A cryptic note lay nearby. It read only "The past." Who wrote this strange message? Vale knew this case began.
