Wuthering Heights author (6)
I believe the answer is:
bronte
'wuthering heights author' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for bronte that I've seen before include "Bell" , "British family of writers" , "Charlotte, Branwell, Emily and Anne" , "Wuthering Heights author" , "Haworth literary family" .)
