20D - First pm novelist (7); I have W?L?E?E
23A - Provenance of Aida (5); I have E?B?A - Euboa ?, why?
26A - Poet with features of clerical cut etc. (5). I suppose this is Eliot but I can't work it out from the clue. Thanks for any answers.
27A is Cheyennes and 24D is Bantu so 14D has to be Iphigeneia which leaves 20D W?L?E?E - not Walpole and 23A E?B?A can't be Egypt or Nubia - any ideas ?
