German enemy author? (5)

I believe the answer is:

defoe

I'm a little stuck... Click here to teach me more about this clue!

'author?' is the definition.
(Daniel Defoe)

'german enemy' is the wordplay.
'german' becomes 'de' (I am not sure about this - if you are sure you should believe this answer much more).
'enemy' becomes 'foe' (I've seen this before).
'de'+'foe'='DEFOE'

Can you help me to learn more?

(Other definitions for defoe that I've seen before include "Robinson Crusoe's creator, d. 1731" , "Daniel -, Moll Flanders author" , "Daniel --, English novelist" , "Daniel . . . . . wrote ''Robinson Crusoe'' (5)" , "Author of Moll Flanders, d. 1731" .)

I've seen this clue in The Hindu.
