Tolstoy's Karenina (4)
I believe the answer is:
anna
'tolstoy's 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 "___ Pavlova, Russian dancer, d. 1931" , "was of very small account in India" , "Former Indian coin, girl" , "Girl - old Indian coin" , "She's a woman, whichever way you look at it" .)
