some questions
- What do we KNOW as a FACT about him?
- What if the z13 and z32 are just a bunch o numbers instead of letters?
- What if the cyphers are just a tool of distraction? I mean, sending the cyphers at the moment he is moving
- What if we search the cryptography books at the time? Like "Cryptography and Cryptanalysis"(1955) - H. F. Gaines
- Are we sure he didn't add question and exclamation marks in his latest codes?
