Mopes about town (5)
I believe the answer is:
epsom
'town' is the definition.
(I've seen this before)
'mopes about' is the wordplay.
'about' is an anagram indicator.
'mopes' with letters rearranged gives 'EPSOM'.
(Other definitions for epsom that I've seen before include "Derby course" , "Home to the Derby and the Oakes" , "Surrey racecourse" , "Classic racecourse" , "& 5 Purgative medicine" .)
