A devil from France, I conclude (5)
I believe the answer is:
fiend
'a devil' is the definition.
(I know that devil can be written as fiend)
'france i conclude' is the wordplay.
'france' becomes 'f'.
'conclude' becomes 'end' (I've seen this before).
'f'+'i'+'end'='FIEND'
'from' acts as a link.
(Other definitions for fiend that I've seen before include "Devil" , "Evil supernatural being" , "Evil spirit, demon" , "Demon, ogre" , "Demon; cruel person" .)
