Hardcover. Condición: Very Good. First Edition. 1976 FIRST U.K. EDITION hardcover with dust jacket. UNREAD COPY with unmarked, crisp-edged, well-bound pages. Jacket shows minor shelf-rubbing and minor edge wear only. A very good, collectible copy! "A popular history of cryptography and secret writing from antiquity to the modern era. Haldane traces the development of ciphers, codes, and concealed communication, showing how each generation of code-makers has been answered by code-breakers. He explains the mechanics of substitution and transposition ciphers and the methods used to decode them, including the medieval Arab discovery of letter-frequency analysis ? a foundational tool of cryptanalysis. The book moves through invisible inks, diplomatic ciphers, and the cloak-and-dagger traffic of earlier centuries before turning to the twentieth-century arenas where signals intelligence became decisive: First World War interception, the Enigma machine, Bletchley Park's work against German naval traffic, and the cryptographic war against U-boat communications in the Battle of the Atlantic. Aimed at the general reader rather than the specialist, it blends historical narrative with accessible technical explanation, drawing on published intelligence histories that were becoming available in the mid-1970s following declassifications of wartime Ultra material. A useful introductory survey for collectors of espionage, intelligence, and code-breaking literature.".…
