Ace evening with no one spreading retribution (9)
I believe the answer is:
vengeance
'retribution' is the definition.
(synonyms)
'ace evening with no one spreading' is the wordplay.
'with no' suggests deleting specific letters.
'one' becomes 'i' (Roman numeral).
'spreading' is an anagram indicator.
'ace'+'evening'='aceevening'
'aceevening' with 'i' removed is 'aceevenng'.
'aceevenng' anagrammed gives 'VENGEANCE'.
(Other definitions for vengeance that I've seen before include "Retribution" , "Retributory punishment" .)
