42a Fine wordplay is hard (6) ??N?S?
36d Main attraction, a hit mostly (4) ?L??
Last letter of 36 = 2nd letter of 42
Also 40a E?E which is unclued. I can find no reference to it in Brewer's
TIA
Flan, 40 A IS mentioned in my Brewer's - as I said, it's contained in the entry for another. It's not great that it's not got an entry of its own, as the others do. I no longer have my copy, but I think this might be the part referred to in the preamble, where two entries join with the theme word, to make a trio.
