Fictional Doone (5)
I believe the answer is:
lorna
'fictional doone' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lorna that I've seen before include "-- Doone, novel" , "girl" , "Female" , "-- Doone (book)" , "and 21 Down: Novel by R.D. Blackmore" .)
