The woman who helped expose her brother’s wife as his murderer says she's insulted by what she describes as a small sum of compensation she's received for her detective work.
Helen Milner, who has been dubbed the Black Widow, was last year convicted of murdering her husband, Philip Nisbet, by feeding him pills, to which he was allergic, in his food.
Mr Nisbit's sister, Lee-Anne Cartier, says she spent up to $100,000 dollars and many months helping to prove Milner was the killer, after refusing to believe an initial police investigation which ruled the death a suicide.
Helen Milner was sentenced to life imprisonment with a minimum non-parole period of 17 years.
Ms Cartier says the settlement for her hard work is not enough, but she needs the money to move on with her life.
She spoke to Kathryn Ryan on Nine to Noon.
