Cannibal killer Katherine Knight lives inside the fearsome Silverwater Women's Correctional Centre in western Sydney where she's known to other inmates as "The Nanna".
The white-haired lady with the benign smile and eyes twinkling behind owlish glasses is the perpetrator of one of the most diabolical murders in the nation's history.
Branded an evil monster, Knight left behind a crime scene so dreadful it repulsed and traumatised those experienced in the field, reports news.com.au.
In prison, however, the first woman killer to be given life without any possibility of parole is seen as a leader by the other "girls" - themselves convicted murderers, baby killers and drug dealers.
Sydney author James Phelps' new book on women in prison, Green Is The New Black provides a rare and incredible insight into how Knight spends her days.
In the 17 years since she was taken into custody, Knight has found religion, paints and knits and acts as a "Queen Bee" sorting out disputes among prisoners.
But the prison officers never take their eyes off her, she is not allowed near knives and she even told one of Phelps' informants that she can't have a cellmate in case she kills again.
Knight's dreadful crime took place on the evening of February 29, 2000 in a suburban house in tiny town of Aberdeen in the NSW Hunter Valley.
Knight is said to be one of the best workers in the head-phone factory and commands the top wage.
"She gets through more work than anyone," Schembri said. "She enjoys her job and takes pride in what she does. Four guards flank her. They watch her every move and are with her every day."
After Knight finishes her day at the headphone factory, she eats lunch before retiring to her cell.
"Her cell is the same size as every other cell in the wing," Schembri said.
"It's a one-out [single person] corner cell at the end of the wing.
"She has a bed, clothes, and the centrepiece of her room is a big old table that she uses for making art. She also sits at that table to write letters."
"She has tried to make it as homely and warm as possible.
"She's going to be there until she dies, so she has made it her home, a place she feels comfortable in."
Knight is also a prolific prison artist. She has become a skilled painter and raises money for the prison by selling her works.
"She's an incredible artist," Schembri said.
"But she never signs anything she does - and never will. She doesn't want anyone making money off her name because she killed someone.
No friends visit
"She doesn't want some sick person buying her art because they think what she did was cool. "The thought of someone hanging something on their wall just because she is a killer repulses her.
"She's amazing with pencil, paint and also pottery. A lot of her pottery is on display in the foyer at Mulawa.
"She has allowed them to sell a lot of it to raise money for charity and the jail - without her signature, of course."
Knight has little left for her outside of prison. Her family and friends have abandoned her. "I never saw her on the phone," Schembri said. "I think all her friends and family have wiped her. I don't think she has anyone on the outside.
"I would say she has zero contact with the outside. Everyone would be on the phone every day, speaking to people outside, but I never saw that with Katherine. It was quite sad."
'The nanna'
Inside Mulawa Max, Knight is known as "the Nanna". She is arguably the most popular inmate in the prison. She is also a peacemaker.
"We called her the Nanna," Schembri said. "She is a gentle soul and not a criminal to me. She is a mediator at Mulawa. She's someone who sorted out problems before they got serious. She would pull the girls in and try to get them to sort out whatever it was before it ended up with someone going into segro [segregation] or getting more time added to their sentence.
"She would stop girls stealing from each other, and stop girls from fighting. But she never did it by standing over anyone. She never raised her hands to anyone. She was just someone who everyone loved."
Knight is also the prison's event planner.
"She organises a big catch-up every Friday," Schembri said. "She organises all the food and makes sure that everyone in the wing is a part of it.
"She includes every single person, even those she doesn't really like. She does it to bring everyone together. It stops a lot of problems from happening."
Top boss
An active officer labelled Knight a prison "boss".
"She's the top boss of the jail," the officer said. "She takes no crap from anyone and absolutely gives it to the guards.
"She knows everything that goes on in the jail, and whatever she says goes."
The officer explained Knight is not your typical prison boss. She did not gain her position of authority by way of intimidation and violence.
"No, she has never raised her hands in prison," the officer said. "Not once. I think she has that level of respect because of her crime. Because she was so brutal. "She has a lot of respect in the inmate population, that's for sure. They simply do not f*** around with her, and that's a fact.
"Most of the other heavies get respect for being tough. Other crims fear them.
"But Knight doesn't really have a record of violence while in jail. I would actually say she hasn't even had a single jail charge since she's been inside. Even the guards respect her a bit. She's the boss, put it that way. She would be the boss of any pod."
Knight is housed in a section of Mulawa called "Willet". She is a Category 4 inmate - the highest and worst category a prisoner can be assigned - and always will be.
