Figure it's more unfeeling (6)
I believe the answer is:
number
I believe this is a double definition.
'figure' is the first definition.
(I know that figure can be written as number)
'more unfeeling' is the second definition.
('numb' can be a synonym of 'unfeeling')
'it's' is the link.
(Other definitions for number that I've seen before include "Count; amount" , "Comparatively torpid" , "comparatively lacking in feeling" , "No longer" , "28 down, for instance" .)
