I think this is one of the better fiction books that I have read lately. The characters are fun and interesting and there is so much to this novel. There is a lot of history and I thought that having such a novel around secrecy and cryptography was really a good idea. Overall there are some slow our skippable parts in the books and the ending is fairly low, but Dengo escape and Bobby's fights are really riviiting. Waterhouse is always interesting.

９００ページを超える大著。暗号をテーマに、いろいろなアイディアと薀蓄を惜しげもなく放りこんでいる。それはいいのだが、肝心の小説としての出来栄えはいまいち。
