That four-year-old is now a young man, said to be the spitting image of his father.

The impact on both him and his brother is felt every day. They have had 13 years of not knowing who killed their father or why. It has left a burning sense of injustice.

“They can’t understand why somebody would do it to their dad and why somebody’s not been caught,” says Veronica.

“They have a huge problem with justice.”

If someone did something wrong in the house, she says, even minor things, the boys wanted them to be punished.

The Wilsons were relatively new to Nairn when Alistair was murdered.

After his death, Veronica says she was worried that people might be awkward with her and the boys.

“It’s not nice being the banker’s widow or the banker’s children,” she says.

She was worried about being accepted fully into the local community.

And for her children, who were entering their school years, she was concerned their classmates would not be allowed round for sleepovers.

“Would you let your child go and stay in a house where somebody had been murdered?” she says.

But the locals did let their children sleep over. And from that very first Christmas without Alistair, when strangers left Christmas presents for the boys, the people of Nairn rallied round the family.
