Published 10 September 2013
When Sir Sidney, a kindly old circus owner, becomes too tired to travel with his show, he places a Help Wanted ad in the newspaper. Enter Barnabas Brambles: "I have a degree in lion taming from the University of Piccadilly Circus." But does Leo the lion need taming? Will Elsa the elephant still get her gourmet peanuts? And what will Brambles say when he discovers Bert and Gert-two mice who travel with the circus on popcorn cleanup patrol? Brambles has big plans: More cities! More shows! No more free popcorn. Soon he's made a big mess of Sir Sidney's Circus, but Leo, Elsa, Bert, Gert, and the rest of the performers agree: The Show Must Go On! Black and white line drawings throughout.

Book 2

As the performers in Sir Sidney's circus discover that friendship and teamwork are more important than winning a trophy for The Greatest Star on Earth, circus mice Bert and Gert write a book on how to be kind for rotten ringmaster-in-training Barnabas Brambles to read.
