Interestingly, there is a cypher used in the book ("Pontifex" AKA "Solitaire") using packs of playing cards. This was developed by Bruce Schneier, an encryption expert. It actually works, and is detailed in a post script. This is no ordinary novel.
This is an outstanding book. I have read it a few/several times, and always find more in it. There are many, very engaging characters, beyond the grandfather-grandson pair into whose heads the reader is allowed.
