A fuss started by some Parisian criminal (9)
I believe the answer is:
desperado
'criminal' is the definition.
(desperado can mean a criminal or outlaw)
'a fuss started by some parisian' is the wordplay.
'a' becomes 'per' (eg 'one a day' means 'one per day').
'fuss' becomes 'ado' (synonyms).
'started by' means one lot of letters go next to another.
'some parisian' becomes 'des' ('some' in French).
'per'+'ado'='perado'
'perado' after 'des' is 'DESPERADO'.
(Other definitions for desperado that I've seen before include "Bravo" , "Bandit, outlaw" , "Gangster" , "Reckless criminal" , "Wild ruffian" .)
