Ghost detectors

At the county fair, ten-year-olds Malcolm and Dandy face a real ghost in the Screaming Mansion, while at home, Malcolm's sister Cocoa's attempt to become Fair Queen has the family in turmoil.

When Malcolm gets a school assignment to write a research report on a long-dead local hero who wrote a book about his adventure-packed life, he is shocked to meet the author's ghost, who reveals that he was a fake.
