If you have read and loved The Little Prince and if you like riddles, this book will probably interest you. What is the meaning of the “magnificent image” at the beginning of the first chapter? Most readers do not find it magnificent at all. Yet, those who know that “the essential is invisible to the eyes” see it as an invitation to think and to learn. The “hat” featured on the same page which actually is something else conveys another hint to look beyond appearance. As you read The Proof by Nine, you will see what is represented by the Virgin Forest mentioned on the first page of The Little Prince. You will grasp the meanings of the pilot, the little prince, the golden muffler of the title character and of the wonderful “fox.” You will see what the “children” really are. The war waged by “sheep” against the “rose” will make profound sense. You will recognize the universal symbols of the tree, the rope, the wheel and the well of science. You will be edified by the experience of the Turkish astronomer. You will observe how all that is relevant to current events and politics for, as stated by the author of The Proof by Nine, “all those things are connected.” You might even ask yourself an exciting question: “Did Saint-Exupéry see the future?” That is why The Little Prince is, in the final words of its author “so very important.”
