Title: Fascinating, you won't put it down till you finish it
Review: I read the book from cover to cover in one sitting and then eagerly dashed to the website to learn more about the cipher challenge that author Singh poses to those of us who think, gee this seems easy, I could take a crack at it. From Egyptian hieroglyphics to Elizabethan intrigue to modern-day Internet encryption, the book eloquently covers the ways in which humans have used codes and ciphers to conquer and cover up their activities. While I was vaguely aware of the Rosetta Stone and the role of Navajo codetalkers during the War, the book made me realize how complex the field is and how slow the progress has been over centuries to refine and evolve these secretive methods of communication. Singh's style is never stuffy or dry. I will be sure to read Fermat's Last Theorem.
