Top Secret: A Handbook of Codes, Ciphers and Secret Writing
Grade 4-8-A wonderful guide to secret writing. Janeczko relates how different codes came to be and why they were needed, and gives some historical examples. The book also contains information and exercises (with answers) on deciphering codes and provides children with the tools to make their own field kit. In addition to numerous codes and ciphers, invisible ink recipes and a number of concealment techniques are included. Humorous black-and-white sketches featuring two figures in sunglasses and trench coats are found throughout the book. The author's upbeat, positive tone is refreshing and his enthusiasm about his topic is contagious. He recommends that readers go to the library to learn more about the subject, and encourages them to use their imaginations and share the fun of secret writing with friends.Cynde Suite, Bartow County Library System, Adairsville, GACopyright © Reed Business Information, a division of Reed Elsevier Inc.
