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

"The author's upbeat, positive tone is refreshing and his enthusiasm about his topic is contagious." — 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?

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.

Back matter includes suggestions for further reading, an author’s note, an answer key, and an index.
