"Three Kings” setting (4)
I believe the answer is:
iraq
'three kings setting' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for iraq that I've seen before include "Middle Eastern country" , "Country with WMD once?" , "Asian area of conflict" , "Putter, perhaps" , "Present-day site of Mesopotamia" .)
