About This Book (from the inside front cover)
This book is all about keeping secrets. It shows you how to set up secret meeting places and a secret post office and how to disguise your messages. It shows you lots of secret codes and signals.
On the first page you will meet the Black Hat Spy. Watch out for the tricks he plays in Spy Trick – these are things real spies have done. You can see what equipment a spy uses and how he hides it quickly in an emergency.
There are messages in code all through the book. See if you can work them out.
