Novelist wandering in a stupor (6)
I believe the answer is:
proust
'novelist' is the definition.
(I know that Proust is a novelist)
'wandering in a stupor' is the wordplay.
'wandering in' indicates an anagram (I've seen this in other clues).
'stupor' with letters rearranged gives 'PROUST'.
(Other definitions for proust that I've seen before include "Great French writer in stupor" , "French novelist - stupor (anag)" , "Remembrance of Things Past author" , "See 8" , "Marcel --, French novelist 1871-1922" .)
