Novelist Grafton (3)
I believe the answer is:
sue
'novelist grafton' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sue that I've seen before include "Take legal case against" , "Bring charges against - girl" , "Take case against in court" , "Entreat; girl's name (dim.)" , "Proceed legally against (someone)" .)
