Since the 1990s a significant percentage of fraud cases have originated in Nigeria. The classic scam is generally known as the "419 fraud" after the section of the Nigerian penal code it breaks:

It occurs to me that a Nigerian princess, such as Clark's dance instructor, might be someone who could be associated with such a fraud. If fraudsters learned of her connection to Clark they might be tempted to use it for a plausible 419 scam. And if this happened early enough it might not be so easily spotted as the common scam it has become.
Is the princess in danger, or involved in shady transactions? Clark will probably want to investigate, and Lois will probably want to help.
Hope someone can do something with this.
