Some ladies' hero in Surrey town (5)
I believe the answer is:
esher
'surrey town' is the definition.
(I've seen this before)
'some ladies' hero in' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ESHER' is hidden within 'ladies hero in'.
(Other definitions for esher that I've seen before include "Sandown Park's location" , "Town SW of London" , "Surrey town and racecourse" , "Town near Sandown Park" , "somewhere in Surrey" .)
