As soon as I read the title, I was thinking about Africa and, since I wrote a paper on it, Leopold II and the Belgian Congo.
As you say, binary, the treasure angle is obvious. The idea of tying in the source of the Nile hadn't occurred to me - excellent idea.
Only difficulty I can see is that it's quite recent and therefore enjoys less mystery.
Perhaps go back several centuries earlier and follow Vasco da Gama?
