Once I deleted the N (thanks to Loge) things started to gel. I have 3 pairs, 2 from acting and 1 from mythology that together comprise 38 cells, but I'll be damned if I can see the one from literature. I have also manged to parse every clue apart from 13a and 31d which I am also finding slightly annoying. For me, this is another listener where grid staring comprises 70%+ of the solve time.
