Dickensian heroine (7)
I believe the answer is:
estella
'dickensian heroine' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for estella that I've seen before include "Sale let (anag) - girl's name" , "Pip's girl in Great Expectations" , "daughter for Abel" , "Dickensian heroine" , "Magwitch's daughter (Dickens)" .)
