Detective Harris arrived at the old mansion after midnight struck. He found the study door unlocked and barely ajar still. A dead millionaire sat slumped in the large wooden chair. A knife protruded from the victim's bleeding chest cavity easily. The window remained open allowing chilly midnight wind entry freely. No signs of struggle were visible in the room anywhere. One muddy footprint marked the floor near the desk then. This murder case would prove hard to solve correctly now.
