That's what I mean aristo, they are all state capitals (there isn't a theme and then variations, it's four matching state capitals)
I have RECA-T for 28 across, so yes, I thought RECART, anagram of all the others (yet again, not one theme word and then three variations, it's just four variations or anagrams of the same letters)
If you look at the preamble again, it gives examples of a theme word and then three linked words.
Manhattan - then three clue words to make up the original theme word
Queens - then three actual Queens
In the crossword, Theme 'A' is 4 state capitals and not one theme word that then links the following three words
And in theme C, it's 4 anagrams and not three anagrams and a theme linked word to connect them.
I'm not trying to be an arse, I enjoyed the crossword thoroughly, but it just didn't seem to be entirely fair with the theme thing.
