My son had one a few years ago which went something like this. He applied for a job as a chauffer (it was in London) for the wife of a man who lived in South Africa. She was coming over to UK for 12 months and needed to be transported around.
Son got job and was also sent a cheque to cover various initial outgoings , which amounted to quite a substantial amount and to wait instructions. Then he was told she was not coming and could he return the money. (a very big trust thing going on). As he had put the money in his bank, he could not return the cheque.
Anyway, to cut a long story short, and I can't remember too much of what else happened, he went to the bank and they said it was a way of money laundering. The bank took over, and that was the last he heard.
...and those who were seen dancing were thought to be insane by those who could not hear the music.FN
