Crusoe's creator (5)
I believe the answer is:
defoe
'crusoe's creator' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for defoe that I've seen before include "Daniel -, Moll Flanders author" , "Author of Robinson Crusoe, d. 1731" , "Author of Moll Flanders, d. 1731" , "Robinson Crusoe's creator, d. 1731" , "Writer of Moll Flanders" .)
