The lie has rebounded on her (6)
I believe the answer is:
sheila
'her' is the definition.
(I've seen this before)
'the lie has rebounded' is the wordplay.
'lie has' can be anagrammed to 'SHEILA'.
Though, I'm not clear how the anagram is indicated.
'on' is the link.
Can you help me to learn more?
(Other definitions for sheila that I've seen before include "Woman in Australian slang" , "16 down's girl" , "Informally, a girl or woman in Australia" , "Girl's name (any Oz girl?)" , "Girl's name; Six down (anag.)" .)
