The best mystery I have ever read is "The Pit and the Pendulum" by Edgar Allan Poe. It isn’t as much a mystery as the others, but it is very suspenseful. I haven’t really read mysteries before though, so that would have to be my favorite one. I like it because there’s a lot of suspense and you never know what’s going to happen.
I think a good mystery starter would be:
Mr. Ethan Richardson was rich. Not your typical rich were you have a million or so, but he had billions of dollars. He was the richest man on Earth- that was until one fateful night where everything changed.
