Jack and Annie went out to buy some ice-cream, then they noticed that the frog creek woods were very quiet. Jack and Annie knew another mission was waiting for them so they went to the magic tree house. There was a part of the book and a letter, it said that they should the find four magicians, the magician of sounds, the magician of light, the magician of invisible and the magician of iron, and learn their secrets. So Jack and Annie went to Paris and searched. They looked a lot of places and found 3 magicians, Edison, Bell and Louis but not the magician of iron. They also found out that all the 4 magicians were in Eiffel Tower so they went up.
