Thanks to Brockwell. I'm becoming a big fan.
Found this very slow going at first, sped through the second half once I got on the wavelength, but solving time definitely over Prize norm. Time put to good use, as the puzzle was delightful with so many excellent clues.
FOI 7, LOI 23.
No single COD. Maybe I liked 9, 7 and 11 the best, but 8, 14, 18, 25, 14, 22a and 13 also appear in my notes. And others could be added.
Now to decipher a theme...(12, 16 and 1) give a hint...not certain but I'm thinking 16 is key.
