Imagine if Sherlock Holmes and Professor Moriarty had the Internet? Then again, Professor Moriarty might have invented the Internet as a way of carrying on his brilliance. He would’ve used his Mathematical genius to write the code. Holmes would’ve looked for ways to break the code.
If Holmes got on the Web, you could have warring tweets between them. Like dueling banjos. They certainly wouldn’t be friends on Facebook though they would have dueling fan pages.
They could certainly make You Tube interesting.
