Bishop visiting killer's shack (5)
I believe the answer is:
cabin
'shack' is the definition.
(thesaurus)
'bishop visiting killer's' is the wordplay.
'bishop' becomes 'b' (abbreviation used in chess).
'visiting' is an insertion indicator.
'killer' becomes 'cain' (Cain who killed Abel).
'b' put within 'cain' is 'CABIN'.
(Other definitions for cabin that I've seen before include "Uncle Tom's little house" , "modest accommodation" , "Room on board ship" , "One's own room aboard" , "Compartment on a ship" .)
