| Dec 15, 2013 at 12:08 | comment | added | David Richerby | @joker I'm sorry for not being very helpful in my previous comment. To figure out a sentence that matches the code, I started by guessing the two-letter word at the start, since the first letter of that appears twice more. I then tried to guess the first letter of the second word, bearing in mind that the last letter of the third word has to be the same. At that point, I had XY ZX-- ---Z -- -X- and you either figure out something to put in the rest of the gaps, or you don't so you try something else. "At Ears Cove, go mad." "Ay, Dave sold to Ian." | |

Changed decrypt for one that reads better.

| Dec 15, 2013 at 11:13 | comment | added | David Richerby | @joker I just wrote the cyphertext on a piece of paper and started guessing letters underneath. I went through a couple of iterations before I found one that made reasonable sense as an English sentence. And, just now, I changed it because I found one that read better. | |
