Friday's creator (5)
I believe the answer is:
defoe
'friday'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 "Gulliver author" , "Daniel -, Moll Flanders author" , "Daniel . . . . . wrote ''Robinson Crusoe'' (5)" , "Writer of Moll Flanders" , "Daniel, writer, d. 1731" .)
