Agree with comments about 9D ... terrific clue and what this setter does best - witty and apposite anagrams. '3 down' is a common cricketing term, and an ingenious red herring in a crossword, so no problem with that, but I still couldn't parse 1A hours after finishing the whole puzzle, so thanks for the explanation Mathi (it was 'second' that threw me). Agree with Chrise re 25A: undoubtedly an 'Ahhh' moment once the (guessed) answer is in place, but almost impossible to work out from the clue alone, so not really fair imo.
PS Re 4D, has the setter got a holiday home in SE France? I'm sure that place cropped up a few weeks ago, too!
