The Codebreakers

David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon its first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure-a masterpiece of the historian's art.
