"Lolita” author (7)
I believe the answer is:
nabokov
'lolita author' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for nabokov that I've seen before include "Russian-American novelist" , "Russian author" , "'Russian-American author, famously of Lolita (7)'" , "Lolita writer" , "Vladimir --, author" .)
