1815 Austen novel (4)
I believe the answer is:
emma
'1815 austen novel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for emma that I've seen before include "Retired chief in Ian Fleming" , "It's a girl - ask me ma" , "classic work" , "Ack -, a term for a.m." , "companion for Nelson" .)
