teenieleek, I worked backwards for 22d. I could find only one possibility for a "partner" given the letters that I had, and I worked from that. Somebody has already said on this thread that it's "Nice", so you want the french personal pronoun.
I had 2 possibilities, other one had y as second letter and that might have worked with french definite article plus a bit but yours is obviously correct, thanks.
Presumably we have 'roc' plus 'l' in a mountain range - it must be the approaching night that clogs my mind. Approaching the clue from the answer twin seems just as nebulous. Another cue?
just read all postings . agree with peterman(6) sometimes hard for aussies et al. Is 6d a proper name? "?t?e?r?e"., and do we have to know our what goes with 24a.? 22d not very Nice ???
