There are four categories: Who, What, Where and Why. Some will be easy, some not. I have as many as six clues to help you along, which I'll supply as needed.

Please limit yourself to one guess, and another guess for each clue I supply. No questions allowed. Partially correct answers won't be acknowledged. Let's see how this goes.

The Case:
A famous man has plotted the deaths of well over a hundred people, many of whom were royalty. Some survived, but many did not. The man is famous the world over for what he's done - yet he's never been tried by a court of law.

The Mystery:
Who are the man's two most famous victims and what is the man's name?
