Secrets, even the ones that stay buried for decades, have a curious way of unravelling. In one rural community in the heart of the Gaeltacht, the disappearance of Barbara Walsh more than 30 years ago was consigned to the annals of history.
Except for an appeal in this newspaper and a report on Raidió na Gaeltachta, the story of the 33-year-old got barely any attention at the time.
The young mother "must have been depressed" became the general theory that quickly emerged. Unable to cope with the struggles of raising seven children, she upped up and left. Case closed.
But thanks to the efforts of her now-adult children, a reckoning with the past, with all its darkest secrets, is about to come hurtling to the fore.
"I look back now and I can see how everything was framed to ensure there would be no questions asked," says Barbara's daughter Jacquie, who was 14 when her mother disappeared.
"I think the view was taken that mum was a nobody. It was a small village that was very clannish back then and there are lot of secrets being kept about what really happened on the night she disappeared."
It was the early hours of June 22, 1985, when Barbara Walsh, who was known as Babe Dara Aindriú, disappeared without a trace.
Her husband Dara Aindriú, who died some years ago, had welcomed his brother Patrick and sister Catherine back from overseas on the night of June 21, with a night out in a local pub.
Most of those in the pub came back to the Walshes' house, and local residents who remember the night in question say those invited included several gardaí and the local priest. The party continued into the early hours.
Exact details of what happened as it drew to a close remain unclear, but it appears that as the gathering dispersed, Barbara's sister-in-law Catherine left the house along with some of the other guests. Barbara then appears to have fallen asleep on the couch while her husband slept upstairs.
Perhaps she was waiting up for her sister-in-law to return, Jacquie has often wondered, but a lot remains unknown.
What has been established is that Catherine did return to the Walsh family home and went to bed, leaving her high heels downstairs.
Barbara was last seen at about 4am, when Jacquie woke to find her sleeping on the sofa.
"That was the last time I saw her," says Jacquie. "She was asleep and I went to wake her up but she didn't, so I got a pillow and blanket and put the pillow under her head and the blanket over her."
It is believed that sometime after Jacquie last saw her mother at 4am, Barbara woke up and left the house.
"I believe that a knock at the window from someone that caused her to get up and leave the house," said Jacquie.
"Mum just left in what she was wearing, black jeans, a white top and she took Jean's beige jacket. Auntie Catherine's shoes were just underneath a small table beside the TV and they were missing the next day so she must have put them on."
The next morning, Jacquie and her young siblings woke up to learn that their mother was not at home.
The couple had no car, and Barbara had no passport. There was no sign of her having packed, and she left her reading glasses behind.
Garda files indicate that no official report of her disappearance was recorded until June 29, a full week later.
The Walsh family home in Roisín na Maithníoch was about 3km outside the village of Carna, Connemara. Separated from the rest of Ireland by vast bogs, bleak terrain and barren, precipitous quartzite mountains, it is a sparsely settled area where some of the customs of the past are still much alive.
"We lived off the land and we had very little," says Jacquie.
With his wife gone, Dara Aindriú raised the seven children with family help, and is said to have been a fine father. His wife was never referred to by him again. "He would never ever talk about it, even if we brought it up," says Jacquie.
"He just bottled a lot up but that was the way of it. There was great stigma attached to the fact that our mother had left us and I know he was heartbroken.
"I remember dreading going back to school the summer after she left. You felt shame over it and that played in to all the secrecy."
In the community of Carna, it was deemed that Barbara, a woman who abandoned her own children, should never be spoken of again.
More importantly, those tied to her disappearance ensured any alternative explanation was never explored. "Everyone in the community just closed up," says Jacquie.
The Walsh children grew up motherless but Barbara was never far from their thoughts. In 2007, gardaí began to look at the case again.
When a letter arrived at the station, purporting to be sent on behalf of the family and saying that the revived probe was upsetting them, shadows from the past seemed to have reappeared.
"It said it was upsetting the family to be digging up mum's case again," said Jacquie.
"It was signed, from the Walsh family or something to that effect. To our knowledge, no one in our family authored any such letter."
With the help of a private investigator, Jacquie established that her mother had no passport, had not changed her name by deed poll and had never applied for her PPS number.
Then in 2009, when undertaking a course at NUI Galway, Jacquie began researching Ireland's Missing Persons Garda website.
She was surprised to see that her mother was not included in it.
She got in touch with the then sergeant in charge of her mother's case to ask why.
"We got the picture up on the website about a year later and it snowballed from there," she says. In 2014, the family wrote to then Garda commissioner Nóirín O'Sullivan about their mother's disappearance and outlined concerns they had with the investigation.
Ms O'Sullivan ordered a cold-case review in 2015, leading to 112 lines of inquiry.
Gardaí interviewed close to 60 people and that November, when a search of Barbara's former home and surrounding lands was ordered, the case came to national prominence for the first time.
But nothing of significance was found.
"I knew the focus would come on our father," says Jacquie. "They had a cadaver dog and I said you can rip the land apart but you will find nothing on dad's land. Our father had no part in this."
Five years later, gardaí are still following up on information gathered during the 2015 review.
"Even now we feel that there are still people with information, particularly in the Carna area," says Detective Sergeant Colm Mac Donnachadha, the officer leading the latest probe.
"We are hoping with the passage of time that circumstances or attitudes my have changed and they may be in a position to come forward.
"It could be something that they think is insignificant when in fact it could be key to cracking this case."
