7d (9) Mendicant from Cumberland - C???E?I?E i thought Carmelite but this impinges on 10ac (5) O damn their Celtic twilight Peter thought Thank god I'm N???E 22ac (8) long distance writer T?R?I?E? and 27ac Shakespearian knight with connections to former heavyweight (3, 6) Sir ?I?R?E
The only write I can think of that matches your letters is (Nadine) Gordimer but I can't see the 'long distance' connection.
I keep thinking it should be Alan Sillitoe!
