Some of them may enjoy an Austen novel (4)
I believe the answer is:
emma
'an austen novel' is the definition.
(I've seen this before)
'some of them may enjoy' is the wordplay.
'some of' says the answer is hidden in the clue.
'EMMA' is hidden within 'them may enjoy'.
(Other definitions for emma that I've seen before include "Female" , "Novel by June Austen" , "Title of novel by Jane Austen" , "classic work" , "Madame Bovary, perhaps" .)
