It's a crime maybe but it brings some peace (9)
I believe the answer is:
armistice
'some peace' is the definition.
(armistice is a kind of peace)
'it's a crime maybe' is the wordplay.
'maybe' is an anagram indicator.
'its'+'a'+'crime'='itsacrime'
'itsacrime' is an anagram of 'ARMISTICE'.
'but it brings' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for armistice that I've seen before include "Fire is prevented by this" , "harbinger of peace?" , "when shooting stops" , "Cease-fire in order to conduct talks" , "Agreement during war to suspend fighting" .)
