Work in vile Parisian prison (8)
I believe the answer is:
bastille
'parisian prison' is the definition.
(I've seen this before)
'work in vile' is the wordplay.
'work' becomes 'till' (tilling is a kind of working).
'in' indicates putting letters inside.
'vile' becomes 'base' ('base' can be a synonym of 'vile').
'till' going within 'base' is 'BASTILLE'.
(Other definitions for bastille that I've seen before include "Fortress in Paris" , "Notorious Paris prison stormed in French revolution" , "French jail" , "Ballet is about notorious prison in Paris" , "Paris prison stormed in 1789 ad." .)
