Dear Emma,

You should know all ciphers have a crib!  And Cribs can look like anything...

This is not even close to being true, especially in the middle ages. Many ciphers were so straightforward, they could be written from a simple alphabetic list of the basic letters or a wheel. Some, done with different methods, didn't even require this. No crib necessary.
