Quasimodo's creator (4)
I believe the answer is:
hugo
'quasimodo's creator' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hugo that I've seen before include "Boy" , "Victor ---, Fr. poet, novelist" , "French romantic writer, Victor, d. 1885" , "Man's name; sci-fi award" , "Victor ---; --- Wolf" .)
