A member of Nigerian royalty who has recently experienced some sort of loss (his son has been killed, estate has been destroyed, etc.) and also has lost his status in South Africa (where he holds his money), and he needs your help getting his 50+ million dollars back into his escrow
bank account. He writes you e-mails telling you that he'll let you keep part of it if you'll front around $5k via wire transfer.
I haven't received my check yet from Mr. Kumalo, that Nigerian Prince who needed my help back in February.
