Weeks passed with no luck. No matter how far we searched or how valiantly we still found nothing. I was beginning to give up hope.

Juniper and I were at the table working on another algorithm together, when Fiona called from the living room.

"Keyland you need to come see this."

I watched on the screen as a news reporter spoke.

"We are here at Old Bailey where James Moriarty stands accused of stealing the crown jewels. On the opposition we have Richenbach hero Sherlock Holmes testifying. This is surely the trial of the century." The newscaster proclaimed. The program ended and Fi shut off the TV.

Everyone looked to me.

"It's starting." I said simply in answer to their stares.

(Some time later.)
"Not guilty! They found him not guilty! No defense and Moriarty's walked free!" John was floored.

Sherlock pulled the phone away from his ear.

"Sherlock? Are you listening?! He's out you know he'll be coming after you. Sher-" John exclaimed.

Sherlock beeped the phone off. He stood up and went to put the kettle on.

'Keyland is safe in Ireland!' He told himself. 'And that is all that matters.' With a resigned sigh he plonked the tea on the table beside his chair and picked up his violin.

Moriarty's POV.

Free as a bird! Just like I planned! Moriarty Grinned. Everything was going swimmingly. I just knew that Sherlock would try to be clever. My Lawyer Crayhill said presenting no evidence was a bad Idea. Ha! What did that idiot know? Oh well I'd pay him off too. Or kill him... The sun shone brightly on the back of my new, grey suit, and I smiled as I picked the lock on 221b baker street. I crept silently up the stairs hesitating when one of them creaked. Sherlock stopped playing the violin as I entered the room.

__________________________________________________________

Sherlock's pov.

"Most people knock. But then, you're not most people. I suppose... Kettle's just boiled." I say annoyedly.

"Johann Sebastian would be appalled...." Moriarty said, picking up an apple, and observing the room. "May I?" He asks.

"Please." I say, gesturing to John's chair. Jim glances at me and takes a seat in the chair opposite. I shoot him an uncomfortable look. Jim takes out a knife absently cutting into the apple as I set up the tea.

"You know when he was on his death bed, Bach, he heard his son at the piano playing one of his pieces. The boy stopped before he got to the end..." He says.

"... and the dying man jumped out of his bed, ran straight to the piano and finished it." I finished for him.

"Couldn't cope with an unfinished melody." Jim states.

"Neither can you. That's why you've come." I observe.

"But be honest: you're just a tiny bit pleased." Jim smiles.

"What, with the verdict?" I ask handing Jim his tea.

"With me..." Jim said softly. "... back on the streets." Jim smiles gazing up at me.

"Every fairy-tale needs a good old-fashioned villain." Jim grins. I stared back at him unamused.

"You need me, or you're nothing." He remarks as I turn to fix my tea. "...Because we're just alike, you and I - except you're boring." He says disappointedly. "You're on the side of the angels." He frowns.

He takes a sip of his tea, still staring at me.

"Got to the jury, of course." I say nonplussed.

"I got into the Tower of London; you think I can't worm my way into twelve hotel rooms?" He says impatiently.

"Cable network." I say, very clever of him.

"Every hotel bedroom has a personalized TV screen ...and every person has their pressure point; someone that they want to protect from harm." He states smiling like a wolf.
I can tell that my flat must be bugged. Otherwise he would be talking plainly about Keyland.

"Easy-peasy." Jim states. I unbutton my jacket and take a seat in John's chair.
"So how're you going to do it..." I ask blowing pointedly on my tea. "...burn me?"

"Oh, that's the problem - the final problem. Have you worked out what it is yet?" He asks softly.

My eyes widen as I realizes Jim is talking about Keyland. I take a sip of my tea and look across my cup to the other man.
"What's the final problem?" He prompts, smiling at me from across his own cup.
"I did tell you..." He sings softly. "... but did you listen?" he asks drumming his fingers on his leg for (What I assume is the benefit of the camera).
"How hard do you find it, having to say 'I don't know'?" I put my cup into its saucer and shrug.

"I dunno." I say nonchalantly.
"Oh, that's clever; that's very clever; awfully clever. Well put." Jim chuckles. I smile humorlessly while putting my cup back onto the tray.
"Speaking of clever, have you told your little friends yet?" Jim asks.

"Told them what?"

"Why I broke into all those places and never took anything." Jim clarifies.

"No." I reply.

"But you understand." He emphasizes.

"Obviously." I admit.

"Off you go, then." he says eating some of what he carved off the apple.

"You want me to tell you what you already know?" I ask.

"No; I want you to prove that you know it." He smiles.

"You didn't take anything because you don't need to." I say pointedly.
"Good." Jim praises.
"You'll never need to take anything ever again." I continue.

"Very good. Because...?" Jim leads.

"Because nothing ... nothing in the Bank of England, the Tower of London or Pentonville Prison could possibly match the value of the key that could get you into all three." I smirk.

"I can open any door anywhere with a few tiny lines of computer code. No such thing as a private bank account now - they're all mine. No such thing as secrecy - I own secrecy. Nuclear codes - I could blow up NATO in alphabetical order. In a world with locked rooms, the man with the KEY is king; and honey, you should see me in a crown." He smiles delightedly. My ears perk up when he mentioned the Key, I get the feeling he is talking about Keyland. Does he know where she is?! I play it off like I have no idea what he is talking about.
"You were advertising all the way through the trial. You were showing the world what you can do." I say in fake realization.

"And you were helping. Big client list: rogue governments, intelligence communities ... terrorist cells. They all want me... Suddenly, I'm Mr Sex."

"If you could break any bank, what do you care about the highest bidder?"

"I don't. I just like to watch them all competing. "Daddy loves me the best!" Aren't ordinary people adorable? Well, you know: you've got John. I should get myself a live-in one." He says to himself.

"Why are you doing all of this?" I ask.
"It'd be so funny..." he says chewing thoughtfully.

"You don't want money or power - not really." I continue.
I watch as Jim digs the point of his penknife into the apple.

"What is it all for?" I ask.
Jim leans forward and says softly. "I want to solve the problem - our problem; the final problem."
He lowers his head. "It's gonna start very soon, Sherlock: the fall."

He whistles a descending note then mimics the noise of something hitting the ground.
"But don't be scared. Falling's just like flying, except there's a more permanent destination." He continues.
He raises his head slowly glowering at me. I snarl then stand and button my jacket.

"Never liked riddles." I clip. Jim stands then meets my eyes.
"Learn to. Because I owe you a fall, Sherlock. I ... owe ... you." He stares meaningfully into my eyes then with a final glare he exits the room. I wait till I hear him leave the front door before examining the apple. He left his knife stuck into it. And a message I O U.
I smirk. Could he be anymore obvious?
