Money for investment in Paris perhaps (7)
I believe the answer is:
capital
I believe this clue is a triple definition!
'money' is the first definition.
(I've seen this before)
'for investment' is the second definition.
(I've seen this before)
'in' acts as a link.
'paris perhaps' is the third definition.
(paris is a kind of capital)
(Other definitions for capital that I've seen before include "city such as London" , "It's terrific in the big city" , "Cardiff, say" , "Money available to produce interest" , "Chief; excellent" .)
