See poor now rich (7)
I believe the answer is:
norwich
'see' is the definition.
(I've seen this before)
'poor now rich' is the wordplay.
'poor' indicates an anagram.
'now'+'rich'='nowrich'
'nowrich' is an anagram of 'NORWICH'.
(Other definitions for norwich that I've seen before include "Administrative centre of Norfolk" , "Largest city in East Anglia" , "Norfolk city" , "County town in E. Anglia" , "E. Anglian county town" .)
