One takes off Parisian art stunt (7)
I believe the answer is:
escaper
'one takes off' is the definition.
(take off can mean to escape)
'parisian art stunt' is the wordplay.
'parisian art' becomes 'es' ('is' in French - 'art' can mean 'is' eg 'thou art').
'stunt' becomes 'caper' (I've seen this in another clue).
'es'+'caper'='ESCAPER'
(Other definitions for escaper that I've seen before include "one getting away" , "it's no longer caged" , "Fugitive" , "One runs away" , "One who gets away" .)
