Fleming returned with Gallico and another author (7)
I believe the answer is:
naipaul
'another author' is the definition.
I know nothing about this answer so I can't tell whether this works.
'fleming returned with gallico' is the wordplay.
'fleming' becomes 'ian' (I've seen this in another clue).
'returned' is a reversal indicator.
'with' means one lot of letters go next to another.
'gallico' becomes 'paul' (I can't explain this - if you can you should give a lot more credence to this answer).
'ian' back-to-front is 'nai'.
'nai'+'paul'='NAIPAUL'
'and' is the link.
Can you help me to learn more?
(Other definitions for naipaul that I've seen before include "V. S. -, two thousand and one Nobel Prize author" , "Sir V.S. --, author" , "V. S. - , novelist (A House for Mr Biswas)" , "Author of In a Free State" , "Sir V. S. -, Br. author" .)
