Go back to the asylum (7)
I believe the answer is:
retreat
I believe this clue is a triple definition!
'go' is the first definition.
(retreating is a kind of going)
'back' is the second definition.
(thesaurus)
'to' is a link.
'the asylum' is the third definition.
(thesaurus)
(Other definitions for retreat that I've seen before include "It may be secluded" , "unhappy manoeuvre" , "secluded place" , "place for meditation" , "care home" .)
