Indifferent in a way, having heartless set of values (9)
I believe the answer is:
apathetic
'indifferent' is the definition.
(synonyms)
'a way having heartless set of values' is the wordplay.
'way' becomes 'path' (path is a kind of way).
'having' means one lot of letters go next to another.
'heartless' means to remove the middle letters.
'set of values' becomes 'ethic' (I've seen this in another clue).
'ethic' with its centre taken out is 'etic'.
'a'+'path'+'etic'='APATHETIC'
'in' is the link.
(Other definitions for apathetic that I've seen before include "Not interested" , "disinclined to act" , "Having little interest, indifferent" , "Indifferent - without emotion" , "Impassive" .)
