Leage of Extraordinary Gentlemen

I have heard of all the characters in the movie, but have never read anything with Professor Moriarty. Can anyone tell me what book(s) he is in?

He is the baddie in the Sherlock Holmes' books.

Heh... first time I heard of the movie, I thought it was gonna be a feature-length The League of Gentlemen Brit flick. Oh, how I was wrong. Still, after seeing the TLoG Christmas Special... I'm a little scared of Germans... and vets...
