EDIT: I'm reuploading this chapter here in 2020 because I have seen people struggling to decode the latest GR cipher... hopefully this will help a person or two who wants to suffer with me XD

Every keyword cipher has a keyword, so make sure you know what the keyword is. In this case, the keyword is "gideon".

Write out the alphabet. Underneath that, write your keyword and then the remaining letters of the alphabet. You cannot repeat any letters.

This is your key to solve the cipher. Use it to decipher the code.

You try!
