Far away in Ancient Egypt, Jackal and Ibis are brought before the Cat Pharaoh to be punished for stealing from the town market. In a merciful moment, the Pharaoh decides to give the two friends one last chance: they must journey up the River Nile to the temple of Karnak and bring back something that has been taken from her - a beautiful and precious Jewel Fish. But she has a warning for the two: Do not take anything else while you are in Karnak. And know that the Jewel Fish is magical. Be sure it does not get wet. Jackal and Ibis are not very clever and ignore the Cat Pharaoh's words, taking a few extra treasures for themselves . . . and disaster follows! It's up to readers to work out from the pages of the book what the Jewel Fish looks like, then log on towww.graemebase.com, where the Cat Pharaoh and Crocodile Prince wait for their treasures to be returned. A cunning mechanical device in the back of the book holds the final key to the puzzle. And on the back of the book's jacket is a poster map of ancient Egypt with facts about the actual places and mythological characters in the story. Complete with hieroglyphics and sparkling jewels, here is a cautionary tale set amongst the wonders of an ancient world, from the bestselling and highly acclaimed author of such classics asAnimalia, The Eleventh Hour and The Legend of the Golden Snail.
