About this deal

McKay traces the increasingly sophisticated use and decryption of coded texts to wage and win wars, to woo lovers, and to conceal esoteric or scientific knowledge throughout the centuries. In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents - the operating instructions of the cipher machine, Enigma. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland.

Still, you can’t help wondering how that story might have read if it had been told from the point of view of Francisco Mojica, the Spanish scientist who first spotted Crispr in bacteria inhabiting salt ponds in the 1990s. The most authoritative and revealing examination yet of the way intelligence--of all kinds--was instrumental in defeating Japan.

It captures the harsh realities of life for those who spent the war in less lauded, yet equally important, secret roles. Many specimens with images, ranging from encrypted postcards to historical messages, are conveniently classified in chapters and their solutions are explained. With their inextricable links to history, mystery and war, codes and ciphers offer a rich seam of material for any author. A comprehensive, yet accessible, resource for a contemporary understanding of the past and present of codebreaking.

In 1974, the British government admitted that its WWII secret intelligence organization had read Germany's ciphers on a massive scale.

Two of the world’s leading experts, Elonka Dunin and Klaus Schmeh, reveal their codebreaking methods and stories. The work of women like Elizabeth Friedman – who got her start unpicking the codes of Prohibition-era liquor smugglers – was one of the war’s best-kept secrets.

A gentle and enthralling introduction for the novice with scores of challenge problems, a guide for the student of classical cryptology, and a delight for the expert with dozens of unsolved problems to attack.Finance is provided by PayPal Credit (a trading name of PayPal UK Ltd, Whittaker House, Whittaker Avenue, Richmond-Upon-Thames, Surrey, United Kingdom, TW9 1EH). They do the intellectual heavy lifting that will engage any reader in the science and art of encryption.
