Thanks Malone for 19a - i had winceyette in in d and was thinking sure instead of yes for the "certain" bit
I have changed 6 so far .... 4 across ones and 2 downs... how many more need altering?
i think I'm down to my last one now...
23d Handle ancient spirit (7) I have ?AIRA?D assume it's a thematic one but I can't work it backwards either!!
Also can't parse the god answer in 25d
Thanks for any help on offer!
Kirky, the first five letters in what you have are the changed part - the clue answer has six letters. The spirit isn't Naiad.
For 25 D, the god might be Ra.
