Big Max, the Best Detective in the World

I know the first book that I ever read on my own was a kid's book called Big Max, the best detective in the world. That was an illustrated book about this guy who was called in by the king of a fictional country because his pet elephant had disappeared. And he thought that the elephant had been stolen. Do you want me to tell you what really happened? Well, I don't know if I want it spoiled for me, but yeah, go on.
