Austen novel (4)
I believe the answer is:
emma
'austen novel' is the definition.
(novel by Jane Austen)
This is all the clue.
(Other definitions for emma that I've seen before include "Mrs Bovary" , "Retired chief in Ian Fleming" , "Title of novel by Jane Austen" , "Ack -, a term for a.m." , "novelist's work" .)
