City scoundrel and US lawyer married (9)
I believe the answer is:
rotterdam
'city' is the definition.
(Rotterdam is an example)
'scoundrel and us lawyer married' is the wordplay.
'scoundrel' becomes 'rotter' (I've seen this before).
'and' means one lot of letters go next to another.
'us lawyer' becomes 'da' (abbreviation for District Attorney).
'married' becomes 'm'.
'rotter'+'da'+'m'='ROTTERDAM'
(Other definitions for rotterdam that I've seen before include "Dutch city and port" , "Major North Sea port - tarred tom (anag)" , "One of the world's largest ports" , "foreign city" , "city abroad" .)
