# Thread: CHAPTER 4 - discussion and clues

1. Hi, Lobster.

Based in the recurrent clues, I am confident that the main cipher in this chapter treats with change of the letters' positions, using the WHOLE alphabet. Afterwards, I am not sure if you have (or you don't have) to use a substitution cipher, but I am sure that at the end you have to throwing out the letters U-Z (numbers 21-26).

what about the clue "the solution to this chapter is easier than you think". I like your idea but it seems complicated

I forget how chapter 3 was solved. did you need to decrypt anything before finding the solution in that chapter?

4. Anybody feeling good about their recent submissions? I feel I have been able to build a good logical case for mine, based on the FB clues and the possible clues in the chapter. Reading the FB clues, I have been able to discern the 'hidden' clues in most of them. I have then consolidated all of them into a common theme. Now I just have to wait for my next rejection email to thwart my hopes...

im pretty conifident about my recent submissions. the worse part is the waiting

Well that changes my whole way of thinking for chapter 4

I wouldn't at all be surprised if I had submitted the first half correctly at some time over the past year, but I'd never know it. I can find approximately 8 different alpha sequences for C4 that have things that appear to be "validators" indicating that they are correct, when clearly this can not be so.

I hear you Lobster! I was really confident about my alpha, but now realizing that I may have to encrypt/decrypt it first, the possibilities really are limitless. I keep going back to the clue " The answer is easier than you think. ". Encrypting or decrypting a solution does not seem easy imo.

I hope Ron releases a key soon to give us some direction!
