“Don’t put on the light. We’re going out. Come on.”
“Come on where?” asked Tim.
“To the fair, of course,” said Tobias. “You want to go to the fair, don’t you? I’ve been waiting for you. I’ve got a broomstick outside the window.”
A funfair arrives in town and Tim desperately wants to go, but Aunt May just doesn’t have the money to give to Tim.
Luckily, Tim’s new friend Tobias thinks of a way that Tim can get into the funfair without paying, make him invisible! Tim and Tobias fly silently into the fair on Tobias’ broomstick, but will they get caught?
