I listened to this in audiobook and I was like "Oh my god it has to be a movie". This is the 4th story that I read by Stephen King and he never fails to amaze his fans. 
 I thought this story is about ghosthunting because of the funhouse and because they said that there's a ghost there but Devin Jones didn't see a ghost but he solved a crime. 
 Brilliant! Everyone should read it!
