Legendary victim making it a cruel anagram (8)
I believe the answer is:
lucretia
'legendary victim' is the definition.
The definition suggests a singular noun which matches the answer.
'it a cruel anagram' is the wordplay.
'anagram' indicates an anagram.
'it'+'a'+'cruel'='itacruel'
'itacruel' anagrammed gives 'LUCRETIA'.
'making' is the link.
Can you help me to learn more?
(Other definitions for lucretia that I've seen before include "raped girl" , "rape victim" , "The Rape of - (Benjamin Britten)" , "Woman in Roman legend" .)
