I've made a tentative start, but puzzled in a few places.
I don't see the parsing for the last 3 letters in 12d
29ac doesn't seem to be in my on-line Chambers. I can see that the last part is an anagram, but what about the first part?
The first answer to 9/25 seems to have a simple answer, which doesn't seem to be defined in the clue?
Thanks in anticipation
