This is my first fic so I am open for reviews I know this is old stuff but I couldn't resist but in this Castle is the best CIA agent. Most don't believe him but they soon will did his family even know the whole story? Will Beckett find out his past?

DISCLAIMER: I sadly don't own the castle series

Castle was heading up to the precinct with two cups of steaming coffee in his hands. It's been a rough week he was thinking about the case they were working on and of course Kate and shlemming. Ever since Demming showed up no one listens to his theories he's just ignored past off like some boring incapable person…

DING!

The elevator door opens and just as I'm about to walk of the elevator I see Shlemming handing Kate her coffee and she's smiling looking at the murder board. I already know who killed the victim, but no one will listen. I step out of the elevator and into the busy bullpen and drop one coffee in the trash. I walk over and try to say something.

Good morning, Beckett

Hey, Castle we just caught our killer he confessed.

Demming figured out who it was and we brought him in and he confessed.

Castle was furious the brother didn't kill his other brother and Becketts giving him some credit.

Sorry detectives but your both wrong it's not how I would right it, said castle.

Rick it's not one of your books its reality not some crazy theory and who cares about your ideas you're not a cop or a detective you're an author, said demming.

Kate looks like she was going to say something but closed her mouth. Castle balled his hands into fists. He didn't even notice the crowd around them watching.

Just because I'm an author and not a cop doesn't mean I'm wrong and I know I'm right on this, said castle.

Why? Do you know something you're not sharing Castle? Asked demming

Now I'm a suspect! said castle

Before demming could even react he was flat on the ground with a bloody nose and bruised face. Castle didn't want to knock him unconscious so he punched him square in the face. While Beckett was helping Demming up he started to yell.

You just shadow us around you don't know anything.

Esposito and Ryan were holding him back from hitting demming again.

Castle couldn't believe they were on his side his supposed to be family turned on him even Kate she didn't say a thing.

Richard Castle I'm pressing charges for assaulting an officer, said Demming

Castle stormed out of the crowded bullpen.

I wonder what kind of academy you even went to ha! You didn't even go to one.

That stopped Castle dead in his tracks he didn't even turnaround he just shouted.

Actually shlemming I did, I was recruited for the CIA I was the best they even want me to run the CIA. Said castle

Your actually lucky I didn't kill you all I had to do was hit one spot!

Oh, and don't bother trying to find my records you wont.

With that castle go on the elevator and left a shocked precinct most laughing they didn't believe it but they soon would.

PLZ review any comments it's my first fic I wasn't sure how to do each character
