All cons breed variations, just like virii. Each variation is a test, and the most successful test breeds into millions. This is the first time I've seen this variant on the Nigerian scam. Unlike the various Nigerian variants, this one has some interesting qualities: mostly good grammar and spelling; an altruistic element (the bait for someone who wants to be a con-man themselves -- the oldest trick in the book!); a young woman's voice:
My name is Haja Laila from Brunei I am a 23 years old and a British citizen who was taken to Brunei by my father 10 years ago. He married me out of my will to a Prince in Darussalam. Over the years I have been able to acquire some money, which I intend to transfer out of Brunei to Europe,after which i intend to flee from Brunei.That is why I contacted you.
I need your assistance because I do not want my husband to know about it. If you know you are capable of handling this transaction contact me immediately. Note also that this transaction must be kept secret and confidential. I await your quick response.
