Adventures of Diggeldy Dan by Edwin P. Norwood

Diggeldy Dan is a most ingenious fellow who lives in a circus called Spangleland. He looks like a clown because he perhaps is a clown but a very special clown who invites the Pretty Lady with the Blue Blue Eyes to meet with the animals of the circus. Many things happen that are just too amazing to talk about because you won't believe them but if you read this book you will perhaps learn that fun is inside all of us. The writing is adult, not childlike, and easy to understand. - Summary by phil chenevert
