“It’s not a problem in this area. I do not even know if they exist in this area. They are from Palermo and they stay there,” she says firmly.

What may be more of a problem, according to her husband, Angelo Campagna, is the inexorable upwards pressure on prices. He says prices are still cheaper than Tuscany — about 25% less for a four-bedroom farmhouse with enough land to build a pool — but that they have risen sharply in recent years.

The Luxtons, meanwhile, feel confident that they bought at the right time. They intend to spend a month a year in their new house and rent it out for £400-£600 per week from June.

Run this rosy-eyed scenario past Bill Blevins, managing director of the international property company Blevins Franks International, and a more complex picture emerges. Blevins agrees that Sicily is becoming more popular among northern Europeans looking for a holiday home as they move away from destinations such as Spain, mainland Italy and France. But he believes that in 18 months or so prices will have dropped 10%-20% as ripples from the stagnant UK property market spread to hit second home sales abroad. He advises waiting until next summer to buy: “You’ll get better value then.”

And while the mafia may not be a problem, for Blevins the real risk lies in other Sicilian traditions. “It’s a relatively new market for foreigners to buy into and old, sometimes incestuous customs carried out by the Sicilians have not always been carried out in accordance with the tax system or the law,” he warns.

Because of the practice of handing houses down through generations, sometimes not registering the transfer to avoid paying death duties, buyers should always use a British-based lawyer, advises Blevins, to check the legal paperwork is correct. Otherwise they could end up responsible for unpaid taxes. Likewise, if a Sicilian owner has borrowed against his house, the loan should be discharged before the sale is completed.

It’s a bit of a minefield — and one Richard Bendy has experienced. A renewable energy specialist from Wiltshire, he has bought a two- bedroom property in Noto and six acres of land on a hillside where he plans to build a house. He discovered that there was a charge against the land and had to persuade the seller to pay it off. “It’s not the British way of doing things,” he agrees. “You have to get to the bottom of things and take time to sort out the detail.”

There are other drawbacks to trying to build and restore houses in Sicily, where the local builders turn out excellent work, but in their own time. Because Noto is a world heritage site all building needs planning permission, which can take several months to come through. Bendy’s travails in putting a roof on his Noto house illustrate the difficulty.

“I have to get permission from the mayor. The road has to be closed. I have been trying to get work started for the past three months but it hasn’t happened. It’s not your sort of place if you are going to be British and want your pool built in a week. You have to adopt a south Mediterranean way of looking at the world.”

To refurbish the house in Noto will cost Bendy between £50,000 and £60,000. That includes the new roof, rewiring, replumbing, new floors and a new bathroom and kitchen.

But Blevins warns you are unlikely to buy “a pile of rubble”, pay building costs and make a handsome profit. “Sicilian building costs are not low and they’re higher if you are not a Sicilian,” he says.

Despite Blevins’s warnings, and even though it’s an earthquake zone — in 1693, Noto was razed to the ground — Bendy is certain this corner of Sicily “is going to be a little gem. The thinking is you cannot really go wrong. Even if it takes two or three years to sort the properties out, it will be a good investment”.

Charlie Luxton is more circumspect. He would be happy to see northern Europeans holidaying here, but only the right kind of people. “It will attract a certain kind of person, fascinated by history, colliding cultures and great food and wine,” he says.

For the last thing these pioneers want is for their find to be corrupted, and they don’t mean by the mafioso.
