Cold rain beat the glass. The pendulum swung very slowly. Arthur entered the dark library. Dust motes danced in moonlight. A silent figure sat there. Lord Blackwood did not breathe. Crimson stained his silk shirt. A silver blade remained inside. Arthur gasped in sudden horror. Cold wind blew the drapes. A muddy bootprint lay nearby. The killer was still inside.
