Inspection (5)

I believe the answer is:

audit

'inspection' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for audit that I've seen before include "Roman Aquae Sulis" , "Stocktake" , "vetting of books" , "Thoroughgoing check" , "Check of books" .)

I've seen this clue in the Evening Standard.
