Animal returned to Arthur's place? (7)
I believe the answer is:
camelot
'arthur's place?' is the definition.
(court of King Arthur)
'animal returned to' is the wordplay.
'animal' becomes 'camel' (I've seen this before**).
'returned' says the letters should be written backwards.
'to' in reverse letter order is 'ot'.
'camel'+'ot'='CAMELOT'
(Other definitions for camelot that I've seen before include "King Arthur's capital" , "mythical place" , "Mythical British kingdom" , "Idyllic situation" , "King Arthur court - or JFK's" .)
