The Code Book contains many fascinating accounts of code-breaking in action, from its use in unmasking the Man in the Iron Mask and the defeat of the Nazis to the breaking of a modern cipher system by a world-wide army of amateurs in 1994. It is especially good on the most recent developments, such as quantum cryptology and the thorny civil liberties issues raised by the advent of very secure cipher systems over the Internet. But Singh's mathematical prowess sometimes gets the better of his journalistic instincts, leading to technical descriptions that unnecessarily disrupt the narrative flow. So buy it-- and have a shot at the 10,000 pound mystery cipher--but be prepared to skip. --Robert Matthews --This text refers to an out of print or unavailable edition of this title.

Amazing book. It's much more of a history book about code breaking through time, with stories told as well as you've come to expect of Singh.

Very well written. Only quibble is that I would have liked to have seen more illustrations, and in colour.Published 3 months ago by Shireen Mohandes
