Query: Go to the top of the class, Enid Blyton!

A relatively unknown set of books here in the states, but unfortunately so. The Famous Five series tells of the adventures of Georgina (George), her dog, Timothy, and her cousins Julian, Dick, and Anne.Five Go Off In A Caravan is one of the three that ties for my favorite Five book. I love them all, of course, but this one is just chock full of humor, good food, fun, and excitement! It's summer hols again, and the Five are traveling in a pair of caravans. They make camp in an area that is also occupied by a circus! They make friends with a circus boy named Nobby and his mischievous chimp, Pongo, who becomes a source of much hilarity. But something sinister is going on in the camp and the children are sure that it concerns Nobby's "Uncle" Dan and his unpleasant friend, Lou the acrobat. What are they hiding and can the children bring them to justice in time?
