Parisian that flushed has one questioned (7)
I believe the answer is:
queried
'questioned' is the definition.
('query' can be a synonym of 'question')
'parisian that flushed has one' is the wordplay.
'parisian that' becomes 'que' ('that' in French).
'flushed' becomes 'red' (red-faced).
'has' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'red' enclosing 'i' is 'ried'.
'que'+'ried'='QUERIED'
(Other definitions for queried that I've seen before include "Expressed doubt about" , "Questioned" , "Marked with "?"" .)
