Novel by Nabokov (6)
I believe the answer is:
lolita
'novel by nabokov' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lolita that I've seen before include "Eponymous nymphette created in novel by Nabokov" , "Literary nymphet" , "1958 novel by Vladimir Nabokov" , "Nabokov's nymphet" , "book" .)
