Overall good, though chapter 6 is kind of a snooze. I remember when the Kryptos statue went up at the CIA heaquarters and being intrigued by it, and the Beale and Voynich chapters are fascinating. I keep hoping that someone someday will crack the Voynich Manuscript code -- now there is some wacky stuff.

Belfield is capable of writing engagingly and accessably about topics most people find difficult, and he certainly has a fabulous sense of humor -- some of his turns of phrase had me chortling and reading out loud to Sarah -- which makes my overall lukewarm impression of this book curious; I should have liked it more than I actually did. But though the individual elements are interesting enough, the overall impression is very scattershot; he constantly references later chapters in earlier ones, for instance, assuming a familiarity with the material that the audience doesn't yet have. The organization of the book is scattershot -- the stories are arranged neither by chronology, nor fame of the unbroken code/cipher, nor complexity -- and Belfield alternates between treating his work as a serious attempt to explore the cryptological lessons/implications of the unbroken code/cipher and a more mass-market pop-science approach. This has some fascinating moments, but overall, not as interesting as it appeared on a bookstore pick-up-and-peruse.

Interesting read about... well, unsolved ciphers! Kind of shows what could happen if you spend too much time and money trying to solve these puzzles, but the lure is there!

It reads like it was written in response to the hype surrounding Dan Brown. Interesting histories, nonetheless.
