Are behind working islander (9)
I believe the answer is:
hebridean
'islander' is the definition.
(someone from the Hebrides)
'are behind working' is the wordplay.
'working' is an anagram indicator.
'are'+'behind'='arebehind'
'arebehind' with letters rearranged gives 'HEBRIDEAN'.
(Other definitions for hebridean that I've seen before include "in Stornoway?" , "Scot!" , "from Scottish island" , "from the Western Isles" , "from Harris, for example" .)
