'If it could happen to Annabel, it could happen to any of us'

He praised the support from police, particularly their family liaison officer, but said it had "brought home just how terrible it is" for victims.

This included hearing some of the voice notes recorded by Annabel herself, played to the jury.

In one, Annabel described George becoming angry because she did not clean his knives properly.

"I can't not make him angry, it's always going to happen," she had said in the voice note.

Peter said that although this was "very difficult" for the family, it was "no doubt powerful evidence" for the jury to hear his daughter's voice.

It was only during the trial that they learned the extent of George's controlling behaviour.

The jury heard that he would fat-shame and gaslight her.

"We knew he had a short fuse and would lose his temper over small things, but we never knew he was capable of physical violence," Peter says.

"And we've learnt how he used silence as one of his weapons," adds Susanna Rook, describing how George would "come home and not talk".

"Red flags need to be noticed," Peter explains.

"Which means that people should share information and people should react on information to prevent tragedies like this happening in the future."

According to the Home Office, a woman is killed on average every three days in the UK.

Peter says it is important to note that his daughter was murdered after she decided that it was time to leave George.

"Of course it's self-evident now that where a controller perceives that they're going to lose the person they control, that is when they can be their most dangerous."

Milne says that although she had become "increasingly concerned" about George's cruel behaviour, she did not think he was capable of physical violence and that Annabel would reassure her.

"Annabel was an incredibly strong woman, and she was very much in control of her own life," she says.

"She was not financially dependent on him. She had a flourishing career. She had loads of friends. She was an incredibly powerful, autonomous person.

"I don't think she realised how much danger she was in. I certainly didn't realise how much physical danger she was in."

Susanna says the whole family have been "shattered" by her daughter's death.

"I think the best word that people have used to me is 'unfathomable'. It is unfathomable that this should have happened," she says.

At their kitchen table, she shares memories of Annabel's childhood and how her "joyful and funny" daughter had made friends wherever she went, including the women she helped support through the MamaSuze group.

"They were just heartbroken," Susanna says, remembering their reaction to hearing what had happened.

"'But she was an angel', they said to me."

"We know that we'll never get over it, but obviously we will manage, and one of the reasons we will manage is because of her spirit," says Peter.

"Because we know she'd be saying, 'come on, don't curl up into a ball just because of me', and we also know that she wouldn't want her life defined by her death.

"She was determined to make life a better place for all these vulnerable women."

"I imagine I'll spend the rest of my life missing her," Milne says.

"The flame of my life has definitely gone out in many ways."

She says she has been "given courage to carry on" by the "tenacious, brave, formidable women" who attend MamaSuze.

She believes Annabel's murder highlights why everyday misogyny and sexism must be tackled.

"I really think that all of us need to look at ourselves, at our relationships, at our friends, and really think about what it is in our society that is causing men to be so angry, so embittered, and so entitled, that if they feel powerless they want to kill us.

"We should all be outraged by this."
