Many thanks Philistine - a perfect middle ground between the excesses of the last few weeks. FOI 11a, LOI 19d (got very confused so put this one aside for a long time), thanks for the pointers I got from here. Too many COD contenders to count but some very nice clueing.
I'm sure I've seen 9a in a Guardian crossword, no doubt Jono can't tell us when it was. Liked the Pauline 13a/18a; I thought we might have a marital theme emerging with 12d and 24a, but nothing else came through.
All the best to all, see you tomorrow
