[Bb] Centre of Gravity, ha ha. No, mine isn't the start, end or middle of anything. Or the second. Or even "a letter in the word 'open'". [Blob] I said not when I said "No-one's got mine yet".
BTW, there is a definition for "Bust down reason" - it's not just a device. I can't tell if there is for "Case bust", which could just mean something that encases a bust ie. "Playtex Brassiere", which is wrong.
[MF]Just an allusion to the clues I was commenting on. But if you can find a solution anyway, don't let me stop you! Am I anywhere on the right lines with my solution to "Bust down reason"?
[Bb] Congratulations! [Raak] You're definitely thinking about it the right way. I agree with Martha that it's a very hard clue (I didn't get it when I was reading the book.) The first letter is B. [Blob] I'm not sure if you are referring to a different occasion, but I clued "Mile End" as More? (4,3) with the idea that it should be read as "M or E"
