Sherlock Holmes has a weakness. Only four people, including me, know about it. And even the others don't realise that it will be the catalyst. The hand that will push him off the cliff. His demon.

Only I know this.

His demon lives in his heart during the day. It's latched around the beating muscle, sucking away feelings like a baby to milk. Laughing when Sherlock hurts. Clawing deeper when Sherlock smiles.

And then at night, it slithers through his ribs and slides up his throat, nestling around his skull.

Sherlock Holmes then has nightmares.

He never remembers them, but that's fine.

It's the aftermath that matters. That widens The Gap.

Sherlock lies in bed, with nobody to go to, nobody to actually care and comfort him. This is his real weakness. And although Sherlock Holmes would never confess it, he needs someone to save him. He saved so many. So many lost souls. And yet his soul is slowly floating away into the darkness, with only a fraying string holding it.

But even so, at the same time he doesn't want to be saved. It's like the way a month flutters too close to the fire. It knows it will die painfully, and yet doesn't move away.

You see, Sherlock Holmes is in desperate need to need someone. Everyone always wants something from him, and although they offer rewards of matter, he longs for something you can't write up in a cheque.

But what nobody knows, not even the ones closes to him, is through Sherlock's tight smile, or forced laughs, he is demanding comfort.

He never gets it of course, much to my delight. And so his demons slowly devour whatever emotions he has left in The Gap.

Soon, he will be empty of everything. And Sherlock will slowly stumble closer to The Gap.

Mycroft Holmes knows this, which is why he bought John Watson into the picture, to try and prevent The Growing Gap.

John Watson knows this, which is why he tries to bridge The Gap.

Molly Hooper knows this, which is why she tries to reach past The Gap.

And I know this. I don't try to do anything with the Gap though. I know it won't work. I've been there before him. Trust me, he'll fall off it sooner or later. I don't mind waiting.

I'll get my fall Sherlock Holmes. Sooner or later I'll get my fall.
