Well I don’t know how to solve it, but it could help for us to take a step back and assess the possibilities.
- None of the puzzles we’ve solved so far have relied on content from previous puzzles, so it’s safe to assume this will be standalone as well.
- DIBEH means nothing on its own, the standard Caesar cipher turns up nothing, and it’s not an anagram.
- Every letter in DIBEH is unique, so if it’s encrypted with a substitution cipher we won’t be able to crack it. This means it can’t be a substitution cipher, as OWI wouldn’t give us an unsolvable puzzle.
- None of Ed’s previous tweets have used asterisks and dashes in the way these tweets have. Either or both may be significant. They could be a reference to morse code, although previous messages from Ed have used . instead of * to represent dots.
- DIBEH is a very short message, so it’s unlikely to be a direct clue such as a URL.
- The second tweet is possibly meant to help us solve the first in some way.
