The tree house was still at the top of the tallest oak tree in woods. Jack and his seven-year-old sister Annie climbed it up.

Still books scattered around the tree house. They held up a book about Ancient Egypt, then they pointed to the pyramid picture with making a wish that they could go to there. They also brought a picture of their hometown in book, Frog Creek, Pennsylvania. It was in case that they would want to come right back home.

As they opened their eyes, the tree house was in the middle of the desert with the strangest sleek cat. But the cat ran away toward a giant pyramid. Then they saw Egyptian funeral parade to the pyramid, but it was mirage.

They stepped into the pyramid, where a hallway went on and on. They were going to a burial chambers which a mummy in it. At that time a tomb robber who tried to steal moved swiftly past them.

Just then another figure was moving slowly toward them. She was made of air, Queen of the Nile. She had waited to go on to the Next Life for a thousand years. She needed the Book of the Dead so Jack and Annie helped her find out it along the massage on the wall in hieroglyph.

Jack and Annie followed the ghost-queen deeper into the pyramid. They saw a real mummy, Queen of the Nile, in a gold box. Jack put the scroll, Book of the Dead, next to the mummy's skull.

When they came out there, they were lost on one of false passages which were built to fool tomb robbers. As they were trapped, they followde the cat's meow. Then the cat disappeared after they came out.

They got back safely.

Until they found three letters of M. One medallion were found on their dinosaur adventure, another from bookmark of the castle book, and the third was shining on the floor in the tree house after today's journey. That was a clue that the tree house belonged to M.
