Mystery surrounds what happened to an antique dealer who vanished 25 years ago after leaving a note saying she would be back in two minutes.

Married Trevaline Evans, 52, disappeared without a trace after sticking the handwritten note in the door of her shop in Llangollen, north-east Wales.

Her husband, Richard, died last year without ever finding out what happened to his beloved wife.

Speaking on the 25th anniversary of her disappearance, her brother Leonard Davies, now 71, remains desperate to discover what became of his sister, who was last seen on June 16, 1990.

'I've heard nothing at all in the last few months, not a thing. But to be truthful I have never given up', he said.

'I have never lost hope that something will turn up. This is a difficult time of year and I have been thinking about her all week.

'I still think about Trevaline a lot and still miss her very much.'

He added: 'I remember the Saturday she went missing as if it was yesterday. If you asked me what I'd been doing a fortnight before, or even yesterday, I couldn't tell you.

'But that day, I'll never forget.'

On the day she went missing, Trevaline left her shop, Attic Antiques, on Church Street, at about 12.40pm, leaving the note on the door.

At about 1pm, Trevaline bought an apple and a banana and was seen crossing Castle Street.

It is thought she may have returned to her shop at this point as a banana skin was found in a waste bin there, though it was impossible to know whether it was the one bought that day.

The last confirmed sighting of Trevaline was near her home on Market Street at 2.30pm.

There were two more suspected sightings of Trevaline later on the day of her disappearance, although both are unconfirmed.

Five minutes after Trevaline was seen on Market Street, a woman matching her description was seen walking out of town - along the A5 towards Corwen, beside the riverside park.

A further one hour and 10 minutes later, at 3.45pm, there was another sighting, this time of her walking into Park Avenue from the direction of the River Dee - and then she vanished.

Speaking in 1992, Detective Chief Inspector Colin Edwards, who was heading the continuing investigation into the disappearance, said: 'It is without doubt the strangest inquiry I have ever been involved with.

'How a happily married woman could vanish without trace on a sunny Saturday morning in a busy town centre is totally baffling.'

Mrs Evan's brother Leonard Davies, 71, says he has never given up hope of finding his sister

Trevaline's husband had been away during the week of her disappearance and was renovating the couple's holiday bungalow near the coast at Rhuddlan.

She had spent a couple of days there but returned to Llangollen on Wednesday, June 13.

When the case was reopened in 2001, the main focus of the inquiry was Trevaline's movements in the days between her return to Llangollen and her disappearance.

An artist's impression of a man in a blazer apparently seen in her company was drawn up and circulated during the investigation in 1990. However, it had failed to bring anyone forward and was later disregarded as no longer accurate by officers in 2001.

North Wales Police have confirmed the case remains open, but the investigation is not currently active.

Mr Davies is refusing to give up hope but said it was unlikely the investigation would be re-activated.

He said: 'The officers who worked on the case at the time, the ones I got to know, have all retired.

'There are no new theories about what happened, or any fresh evidence, and I realise the police have financial limitations.
