Fictional Karenina (4)
I believe the answer is:
anna
'fictional karenina' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for anna that I've seen before include "Miss Karenina" , "Girl's name (palindrome)" , "The name's the same,either way" , "copper, once, in India" , "Old foreign coin" .)
