WHB Sutherland Ltd is hardly the most obtrusive of businesses: a smallish pharmacy servicing the needs of the residents of Thurso, Britain's northernmost mainland town. It's not the sort of shop you would make a special trip to - unless, that is, you have the desire to be a millionaire.
The desire, however, must be mixed with more than a little credulity.
The scam goes like this: an unsolicited phone call or email from a Nigerian who informs you that you have inherited an oilfield. Considerable wealth - generally proffered at around $41m (£23m) - will be yours. But, first, there is the small matter of an upfront fee.
Should you have any doubts about the veracity of the claim, there is headed notepaper and official-sounding titles to allay your fears. Then, of course, there is always the bank.
A telephone call to the Continental Trust Bank in Thurso, Caithness, should set your mind at rest. On the end of the line you will hear a friendly bank manager, albeit with an African accent not commonly heard in the remotest parts of rural Scotland, who will reassure you what a good idea it is to deposit $57,000 to secure so much more capital.
Should you still harbour doubts, the bank's address will be an obvious reassurance. The Continental Trust Bank is located at 9 Trail Street, Thurso. If anything goes wrong you can always pop up there personally, despite the somewhat lengthy journey, and speak to the manager face to face.
And that is what at least two couples did.
Unfortunately, 9 Trail Street Thurso is home to WHB Sutherland Ltd, a unwitting pharmacy with not even a passing connection to Nigerian oilfields or banks. "We had a Mediterranean couple come in - either Spanish or Italian - looking for the bank who were very upset by the whole thing. We suggested they should contact the police," said Andrew Paterson, manager of the pharmacy. "We then had an American couple who took it a little better."
Although the scam, known as the advance fee fraud, or the Nigerian 419 after the Nigerian penal statute which deals with it, has been around since the 1980s and is perhaps the most widely publicised on the internet, people from across the world have been duped by its Thurso variation.
Would-be millionaires from Norway to New Zealand have been contacting the pharmacy in search of their missing money.
Arlen Hughes, from Wyoming, in the US, fell for it.
"I received a phone call from a fellow in Nigeria saying that I had inherited an oil company," he told BBC Radio 4's Today programme. "They were very professional. I found a registered number in Scotland and so the researches I had found led me to believe they were on the uppity up."
But the number Mr Hughes was calling in Thurso was, in fact merely a conduit for another number in London.
"We have received a number of complaints from people about this," said a spokesman for Northern constabulary. "The address given out does lead you to the chemist in Thurso, but the telephone number is transferred down to London so our investigations have been minimal."
Spam email cons initiated by Nigerians are notorious on the internet. They follow the same pattern and there are more than 150 sites such as scamorama.com dedicated to exposing some of their more ludicrous claims, but many people still fall for them each year.
Some sites claim Nigerian gangs raked in as much as $50m last year from variations on their 419 scam.
