The detective found the body sprawled across the library floor. A silver letter opener rested beside the victim's pale hand. Rain hammered the windows while thunder masked every distant footstep. Nobody had heard the scream that ended Lady Whitmore's life. The clock on the mantel had stopped at midnight exactly. Blood stained the Persian rug in a widening dark circle. She had been reading when death arrived without any warning. Three guests claimed alibis that crumbled under careful questioning tonight. The detective closed the door and began his grim investigation.
