We all know that Humpty Dumpty is an egg. But did you know he was born into the travelling circus? Or that he had a little sister, Dimity? At last her story can be told! Shy as her big brother is bold, Dimity prefers the shadows to the spotlight and never joins her performing family in the tent at showtime. But one fateful afternoon, Humpty - with time on his hands - climbs the factory wall at the edge of the circus ground, and slips. It is Dimity, not all the King's horses or all the King's men, who finds her voice - and her courage - and saves his life!
