Some unfinished business in bogs Earl concludes (5,4)
I believe the answer is:
loose ends
'some unfinished business' is the definition.
(I've seen this before)
'bogs earl concludes' is the wordplay.
'bogs' becomes 'loos' (I've seen this in another clue).
'earl' becomes 'e'.
'concludes' becomes 'ends' (I've seen this in another clue).
'loos'+'e'+'ends'='LOOSE ENDS'
'in' acts as a link.
(Other definitions for loose ends that I've seen before include "Unfinished business" , "items to be settled" , "details yet to be explained" .)
