Detest crime that involves injuring men (5)
I believe the answer is:
abhor
'detest crime that involves' is the definition.
'abhor' can be an answer for 'detest' (I've seen this in another clue). I am not sure about the rest of the definition.
'injuring men' is the wordplay.
'injuring' becomes 'abh' (I can't justify this - if you can you should give a lot more credence to this answer).
'men' becomes 'OR' (military abbreviation for Other Ranks).
'abh'+'or'='ABHOR'
Can you help me to learn more?
(Other definitions for abhor that I've seen before include "Find horrible" , "Recoil from" , "Find disgusting" , "Dislike very much" , "can't stand" .)
