A place to go for moles? (6)
I believe the answer is:
agents
'moles?' is the definition.
(mole is a kind of agent)
'a place to go' is the wordplay.
'place to go' becomes 'gents' (gentlemen's toilet).
'a'+'gents'='AGENTS'
'for' is the link.
(Other definitions for agents that I've seen before include "Representatives" , "Instruments" , "Spies" , "They do business on behalf of others" , "They act for actors" .)
