Egyptian secrets take center stage in this interactive mystery where boys and girls can solve codes and puzzles right along with the multicultural cast of characters.

Cody, Quinn, Luke, and M.E. love playing around with codes. In fact, they love codes so much they have their own club, with a secret hideout and passwords that change every day.

After learning about steganography, the study of concealed writing, the Code Busters discover that artists have been hiding secret messages in their artwork for centuries.

A clue hunt on a class trip to the Rosicrucian Egyptian Museum leads the Code Busters to an artifact that doesn't seem to quite fit with the rest of the collection. Could it be a forgery? The Code Busters code-cracking skills and new knowledge of hieroglyphic messages will help them get to the bottom of this mystery, but they better think fast before the criminal tries to frame them!
