The best mystery story I have ever read would be The Pit and the Pendulum by Edger allan poe. I just recently read it in are mystery unit in languege arts. What I really enjoyed was how the story ended. He kept you thinking.
I walked into his room, and saw him. Dead, lying in a puddle of blood. What was I to do? Would I be a suspect? I had to do something. There would already be eveidence that I was here, so should I report it? I paced back and fourth, thinking. Later I realized i was leaving bloody footprints. I paniced. I had no time. I left with blood stained hands, my best friend crammed in the trunk of my car.
