Crime turned out not quite so uncharitable (9)
I believe the answer is:
merciless
'quite so uncharitable' is the definition.
'merciless' can be an answer for 'uncharitable' (I've seen this before). I am not sure about the 'quite so' bit.
'crime turned out not' is the wordplay.
'turned out' indicates an anagram.
'not' becomes 'less' (I've seen this in other clues).
'crime' anagrammed gives 'merci'.
'merci'+'less'='MERCILESS'
Can you help me to learn more?
(Other definitions for merciless that I've seen before include "Showing no compassion" , "Totally unforgiving" , "Ruthless" , "Uncharitable" , "Cruel" .)
