They're names that haunt us down the decades – the list of snatched and stolen children, from Holly Wells and Jessica Chapman to Madeleine McCann, whose fate grips not just a suffering family, but the nation.
And for a brief but agonising time in 1994, the name of baby Abbie Humphries was among them.
Abbie was just three hours old when she was taken from her cot in a Nottingham hospital by a woman posing as a nurse. A huge police operation was launched to find the missing child.
Physically shaking with fear, her distraught parents, Roger and Karen, went on television pleading for clues, but it still took 16 heartbreaking days before Abbie was finally found.
Having been through enough terror and drama to last a lifetime, it was no surprise when the family decided to put it behind them for a gentler life in New Zealand.
Yet today, 27 years on, they face an even graver tragedy.
Abbie Sundgren, pictured with husband Karl, is now fighting brain cancer, a year after mother Karen Humphries died from breast cancer and 27 years after she was kidnapped from hospital at three hours old and reunited with her parents 16 days later
Last year, Abbie's mother passed away aged just 59 after a seven-year battle with breast cancer. And now, in a moving interview, Abbie reveals that she, too, is fighting for her life.
The headaches that plagued her in the weeks after her mother's death in September last year were not, as she presumed, the effects of grief but the result of a Grade 4 brain tumour.
When doctors delivered the prognosis, they predicted that Abbie might survive a year. Two if she was lucky. It is a form of cancer that cannot be cured.
As Abbie begins a new round of expensive radiation and chemotherapy following surgery to remove a second tumour in July, it would be understandable if she were furious at her misfortune.
Instead she chooses to be serenely optimistic – in the spirit of a true survivor, perhaps – even as she and her husband, Karl, worry how they will fund the £50,000 treatment that could hold the cancer at bay and give her more years of life.
'There is no point feeling angry or blaming anything,' she says. 'We have just had a terrible amount of bad luck. I usually choose to look at the positive side of everything. It makes everyone feel better.'

Chatting the day before more chemotherapy, even her tenacious spirit cannot quell the sense that life is not supposed to be like this. After all, Abbie was the baby who came through.
And she is the reason, in part, why her parents chose to leave Nottingham and build a new life on the other side of the world. Roger and Karen were determined that Abbie and her siblings, Charlie, now 30, and Alice, 23, would feel safe and happy in a country where bare feet, back-garden cricket and beachside barbecues were the norm.
Abbie became a champion swimmer, representing her new country. She earned a degree in psychology and criminology before a career, first as a flight attendant, and then in IT. In 2017, she married Karl Sundgren, her teenage sweetheart.
While her parents never hid the abduction from Abbie, she first became aware of the magnitude of the case at the age of ten when she found a collection of press cuttings and a message of goodwill from Princess Diana – with whom she shared her July 1 birthday – during the house move.
And she only appreciated the full drama involved as recently as last year when she watched The Secrets She Keeps – a TV drama loosely based on her abduction – starring Downton Abbey's Laura Carmichael as the kidnapper.
But Abbie has always been aware of the legacy of what happened to her. As a child she felt loved and cared for by her teachers, and her dad would have moments of being hyperprotective.
'It was like everyone always knew who I was,' she reflects. 'Mum told me how much it had affected Dad, and as I was growing up it was like he had flashback moments and had to know where I was right then and there. He'd call me out of nowhere and be a bit strange.
'He felt what happened was his fault, because Mum was a midwife at the hospital and it wouldn't have happened if she was in the room.'

Nearly three decades have passed but the kidnapping from The Queen's Medical Centre in Nottingham remains one of the most audacious in British history.
Britain was on tenterhooks in that hot summer of 1994 while Karen and Roger grappled, day after day, with not knowing if their daughter was alive.
Coming just three hours after Abbie's birth, the abduction had been traumatic. Karen had stepped into the corridor for a few minutes to make a phone call, leaving her husband with the baby.
When she returned, Roger explained that a nurse had come to take Abbie for a hearing test.
Karen immediately knew something was wrong. Then, with dawning horror, it became clear the woman had just walked out of the hospital with the baby in her arms.
Roger scoured the corridors and the car park to no avail and by night, a huge police operation had swung into action. Behind the scenes, Roger and Karen were fearing the worst. What if the woman who took the baby couldn't cope? What if she ditched Abbie where no one could find her? What if she had more sinister intentions?

Working on a premise that the abductor had recently lost her child, or could not have one, the police urged the family to appeal for information.
Television footage shows their despair. 'Whoever has taken our baby can they please, please give her back,' pleaded Karen, as an ashen Roger held his wife. 'We've got a little boy who wants to know where his baby [sister] has gone.'
As she would explain, the vital bonding between mother and baby had begun, giving the couple no choice but to fight their fears and believe they would get Abbie back.
In the end, it was on the third police visit to a house in the Nottingham suburb of Wollaton that Abbie was found safe and well. They had been tipped off that a young woman, a former dental nurse called Julie Kelley, living there with her boyfriend and his mother, had been pregnant and expecting a boy. When she came home with a girl instead, the neighbours became suspicious.
Pleading guilty the following month, Kelley was put on probation for three years and treated for a severe personality disorder. It was reported that she had faked the pregnancy to persuade her boyfriend not to leave. She has gone on to have a family of her own.
It is a happiness which has been denied Abbie, who refuses to indulge in self-pity even as she
