Scottish town in love with outlaw (4)
I believe the answer is:
oban
'scottish town' is the definition.
(I've seen this before)
'love with outlaw' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'with' means one lot of letters go next to another.
'outlaw' becomes 'ban' (banning is a kind of outlawing).
'o'+'ban'='OBAN'
'in' is the link.
(Other definitions for oban that I've seen before include "Northern port" , "port required" , "small Scottish port" , "Port in western Scotland" , "Argyll seaport" .)
