Elaine R. reviewed How to Write and Decode Secret Messages (Codemaster , No 2) on + 2 more book reviews
This is an excellent book. Probably its best audience will be youngsters between the ages of 8 or 9 and 12 years old. There are many fun to do ideas for secret messages and they are presented in an intriguing manner. The only negative is that the decoder card is missing from every copy I looked for on half.com and eBay and this website, as well. Unless it is purchased new, I guess we will have to do without the decoder card! Thank you PBS for your wonderful service.
