Distant, unsympathetic (5)
I believe the answer is:
aloof
I believe this is a double definition.
'distant' is the first definition.
(synonyms)
'unsympathetic' is the second definition.
(I've seen this in another clue)
(Other definitions for aloof that I've seen before include "Displaying supercilious reserve" , "Blood deficiency" , "Unpleasantly cold" , "Indifferent - by oneself" , "Standoffish like a fool" .)
