Dickens girl (4)
I believe the answer is:
nell
'dickens girl' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nell that I've seen before include "Little -, (Dickens char.)" , "Orphan girl" , "- - Gwynne" , "little Miss Trent?" , "-- Gwyn, 17th-century actress" .)
