What do you do if you crack cryptography puzzles (cryptograms) in Kevin Mitnick's book, the one about him on the run from the FBI all those years? When he asks you to write tougher cryptograms for the paperback edition, you write puzzles that are tough as nails. I made sure the first 7 can be cracked with paper and pencil alone. The first three should be a snap for anyone with a little experience. There are no guarantees of an easy time after that.
The paperback edition of Ghost in the Wires is out!!! It has all new, much more difficult codes to crack. Thanks again to @airdisa
