Money-drawer in corrupt French fortress (8)
I believe the answer is:
bastille
'french fortress' is the definition.
(I've seen this before)
'money-drawer in corrupt' is the wordplay.
'money drawer' becomes 'till' (I've seen this in another clue).
'in' is an insertion indicator.
'corrupt' becomes 'base'.
'till' placed within 'base' is 'BASTILLE'.
(Other definitions for bastille that I've seen before include "Old fortress" , "Parisian prison stormed on July fourteenth, seventeen eighty-nine" , "Building stormed in Paris" , "Historic French prison" , "Paris prison, now opera" .)
