Frankenstein author (7)
I believe the answer is:
shelley
'frankenstein author' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for shelley that I've seen before include "Writer of To a skylark" , "Percy Bysshe . . . . . . ., great English poet" , "Author of Frankenstein" , "Ode to the West Wind poet" , "Author of Ode to the West Wind" .)
