French author in Inverness (5)
I believe the answer is:
verne
'french author' is the definition.
(Jules Verne)
'in inverness' is the wordplay.
'in' says the answer is hidden in the clue.
'VERNE' is hidden within 'inverness'.
(Other definitions for verne that I've seen before include "Jules --, French writer" , "See 27 Across" , "French novelist" , "Jules ..... wrote ` `20,000 Leagues under the Sea' '" , "Jules --, French author" .)
