He showed some cleverness as an author (5)
I believe the answer is:
verne
'an author' is the definition.
(I've seen this before)
'he showed some cleverness' is the wordplay.
'VERNE' is hidden within the letters.
But, I am unsure how this is indicated.
'as' is the link.
Can you help me to learn more?
(Other definitions for verne that I've seen before include "Jules --, French author" , "Jules ..... wrote ` `20,000 Leagues under the Sea' '" , "Jules --, French writer" , "Science-fiction writer" , "French novelist" .)
