Rain hammered the dark windows of the old mansion. Inside, guests gathered for dinner in quiet conversation. Suddenly, a scream pierced the silence of evening. Everyone rushed upstairs to find a horrible sight. Lord Pemberton lay motionless upon the Persian rug. His glassy eyes stared blankly at the ceiling. Blood pooled beneath his head in crimson horror. Someone in this room had committed cold murder. Detective Sinclair arrived at exactly ten o'clock sharp. His keen eyes surveyed the scene with interest.
