One More Buchan Bit

I've been obsessing about John Buchan and his arch-villain, Dominic Medina. I'll give it up, but only after this curious footnote: Medina may be mostly forgotten but he has at lteast modern day fictional analog. Consider: Dominic Medina has

1. the first name of a saint, and
   
2. the second name of an exotic faraway place—and
   
3. it ends in a vowel.
   

Now consider the most successful fictional villain ever.
