Crossword Genius

Author can't serve bananas (9)

Ross

I believe the answer is:

cervantes

'author' is the definition.
(I've seen this before)

'can't serve bananas' is the wordplay.
'bananas' is an anagram indicator (informal term for mad).
'cant'+'serve'='cantserve'
'cantserve' is an anagram of 'CERVANTES'.

(Other definitions for cervantes that I've seen before include "Spanish writer" , "Bookmaker" , "Author of the novel 'Don Quixote'" .)

I've seen this clue in The Sun.
