Top Secret: A Handbook of Codes, Ciphers, and Secret Writing

Hardcover (Candlewick April 12, 2004) , 1st edition
Pssst! Inside these TOP SECRET files is everything sneaky young agents need to know about making-and breaking-their own secret codes.

Do you know the difference between a code and a cipher? Can you tell a St. Cyr slide from a Cardano grille? Did you know that a substitution cipher caused Mary Queen of Scots to lose her head? Don’t look now, but packed into this practical field guide is everything a young person needs to know about the art of concealment — making and breaking codes, mastering cipher systems, and experimenting with secret writing. Offering plenty of hands-on practice sessions, tips for creating a code-making kit, sidebars on secret codes in history, and an amusing pair of spies to illustrate techniques, Paul B. Janeczko’s tantalizing TOP SECRET won’t stay a secret for long.
