Some problem, maybe, in a Jane Austen novel (4)
I believe the answer is:
emma
'a jane austen novel' is the definition.
(novel by Jane Austen)
'some problem maybe in' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'EMMA' can be found hidden inside 'problem maybe in'.
(Other definitions for emma that I've seen before include "Madame Bovary, perhaps" , "young woman in novel" , "Ack -, a term for a.m." , "Novel by June Austen" , "Female" .)
