"The Old Curiosity Shop" girl (4)
I believe the answer is:
nell
'the old curiosity shop 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 "Orphan girl" , "Dickensian heroine" , "-- Gwyn, 17th-century actress" , "- - Gwynne" , "Little -, (Dickens char.)" .)
