Some grab at hero in city (4)
I believe the answer is:
bath
'city' is the definition.
(English city)
'some grab at hero' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'BATH' is hidden within 'grab at hero'.
'in' is the link.
(Other definitions for bath that I've seen before include "place of Chaucer's wife" , "Water container for washing" , "Avon city - tub" , "where one may pull the plug on a singer" , "Large tub" .)
