In anger, even get retribution (7)
I believe the answer is:
revenge
'retribution' is the definition.
(I've seen this before)
'in anger even get' is the wordplay.
'in' indicates the answer is hidden within the clue.
'REVENGE' can be found hidden inside 'anger even get'.
(Other definitions for revenge that I've seen before include "Ship remembered in verse" , "Satisfaction taken for injury" , "An eye for an eye" , "Retribution" , "Malicious retaliation" .)
