The Cryptogram Challenge: Over 150 Codes to Crack and Ciphers to Break

For thousands of years the code makers and code breakers have battled for possession of vital secrets. This book contains many of the ingenious codes that have been weapons in that ongoing conflict. It gives readers an inside look at some of history’s most groundbreaking codes—by everyone from Caesar and Leonardo to Norman Schwarzkopf—detailing how each code was constructed and how it was used. With one hundred illustrations and seventy-five messages for readers to decipher, The Cryptogram Challenge is both instructive and entertaining, offering readers of all ability levels a chance to test their knowledge of code cracking, and an invaluable insight into some of the greatest written languages in history.
