"The authors upbeat, positive tone is refreshing and his enthusiasm about his topic is contagious." â?? SCHOOL LIBRARY JOURNAL (starred review) Pssst! 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 the discovery of a substitution cipher caused Mary Queen of Scots to lose her head? Donâ??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. Janeczkoâ??s tantalizing TOP SECRET wonâ??t stay a secret for long.
