Wicked, hid lantern in back of beyond (10)
I believe the answer is:
hinterland
'back of beyond' is the definition.
(thesaurus)
'wicked hid lantern' is the wordplay.
'wicked' is an anagram indicator.
'hid'+'lantern'='hidlantern'
'hidlantern' with letters rearranged gives 'HINTERLAND'.
'in' acts as a link.
(Other definitions for hinterland that I've seen before include "Remote inland areas" , "remote country region" , "Remote area of a country" , "area around a port" , "Remote areas of a country" .)
