Prologue

It had taken years, years of planning to get to this very moment. Jim Moriarty had needed some help, but all participants were immediately killed. Not by him of course, Jim Moriarty never liked to get his hands dirty. He had hired people to do that for him.

All that had to happen now was for Sherlock to follow the script. If everything went as planned, then Sherlock would end up broken on the streets below and Richard Brook would thrive. The human race are the most foolish species in the universe. How could they actually believe what had been going on was real? Jim Moriarty wasn't lying when he said he had his ways to fool the simple human mind.

The only problem was, Sherlock Holmes' mind was not simple. He needed to be destroyed. Burned. He was #1 on the list of people-to-kill. Since he was one of the most brilliant men alive, it was hard for Jim Moriarty to find a way to get rid of him, but they had. It was simple. Sherlock Holmes would destroy himself.

As Jim Moriarty stood on that rooftop, waiting for Sherlock to arrive, he was calm. No matter what happened, Jim Moriarty would come out on top. Nothing could go wrong!

At last, Sherlock arrived, "Ah! Here we are at last - you and me, Sherlock, and our problem - the final problem," Jim said, as he blasted Stayin' Alive from his phone, which he held high in the air like a prize. "Staying alive! It's so boring isn't it?"

Jim turned off his phone angrily. When Sherlock said nothing, he continued, "It's just... staying. All my life I've been searching for distractions. You were the best distraction and now I don't even have you. I've beaten you. And you know what? In the end it was easy. It was easy. Now I've got to go back to playing with the ordinary people, and it turn out you're ordinary just like all of them."

Again, no reply, "Ah well. Did you almost start to wonder if I was real? Did I nearly get you-"

Finally Sherlock spoke up, "Richard Brook."

Jim smiled. He knew exactly what Sherlock was saying, "Nobody seems to get the joke, but you do."

"Of course."

"Attaboy."

"Rich Brook in German is Reichen Bach - the case that made my name," Sherlock said. That name had been simple. Jim was fluent in all the languages of planet Earth so it was easy to find a translation that had a nice name in it.

Jim started pacing in circles around Sherlock, "Just trynna have some fun." When he saw the rhythm that Sherlock was tapping on his fist, Jim smiled. This really was a clever man. "Good. You got that too."

"Beats like digits. Every beat is a one; every rest is a zero. Binary code. That's why all those assassins tried to safe my life. It was hidden on me, hidden inside my head - a few simple lines of computer code that can break into any system."

"I told all my clients: last one to Sherlock is a sissy."

Sherlock gestured to his head, "Yes, but now that it's up here, I can use it to alter all the records. I can kill Rich Brook and bring back Jim Moriarty."

Jim looked at Sherlock in disappointment. He had expected more from someone as special as him. Jim knew that the trick to getting at Sherlock was to taunt him; leave him wanting to know more. So he decided to tease him a bit.

"No, no, no, no, no, this is too easy. This is too easy." Jim paused for a moment, just to let Sherlock process what was going on. When he felt Sherlock begin to panic, that's when he continued, "There is no key DOOFUS!" Jim screamed. The confusion on Sherlock's face almost made Jim laugh.
