Emily and James's teacher Mr. Quisling is up to something mysterious. First, there's the news clipping with an unusual note that he drops at a book event. Then Emily and James discover their teacher has been receiving encrypted messages in a series of Mark Twain books hidden through Book Scavenger. When Emily and James decipher the messages, they begin to suspect Mr. Quisling is hunting a long-rumored treasure of buried gold.

As the Germans waged a brutal war across Europe, details of every Nazi plan, every attack, every troop movement were sent over radio. But to the Allied troops listening in―and they were always listening―the crucial messages sounded like gibberish. The communications were encoded with a powerful cipher, making all information utterly inaccessible … unless you could unlock the key to the secret code behind the German’s powerful Enigma machine.
