To satisfy the spy in everyone, a vintage-looking covert booklet with a sneaky cipher wheel inside. Write and decipher coded messages using a substitution cipher method by turning the wheel inside the front cover. Write your message on the included notepad inside. To write messages with a friend, make sure you're both using the same cipher wheel, set to the same key letter. (So two booklets might be helpful, or more if you want to trade messages with a group.) Instructions are included on the first page of the notepad inside.

Note for the curious from Christy: the cipher wheel (or code disk) was invented by Italian architect Leon Battista Alberti in 1467. Click here for more details. I first saw it in this book as a kid, which I still have!
