Jack and Annie came back home. They looked out the tree house window and noticed that the light of their house was turned on. They hurried up to take off the woods. When they got home, they heard the sound of running water from the bathroom. The home was safe and cosy.

Before going to bed, Jack wanted to take a note. He found the blue bookmark on his pack. It must be fallen from the castle book. And there was the letter M on it. It was the same M on the gold medallion. One mystery solved. The person who dropped the gold medallion in the time of dinosaurs and the person who owned the books in the tree house was the same person.

Jack tried to take a note again but his eyes shut soon. Jack dreamed that they were riding with the knight again.
