A/N: My first foray into Castle Fan Fiction and my first ever fiction based on a preview, so please be kind. It nice and short too!

Also in case you didn't know – there are not mine!

"Close the door Detective"

Becket did as Captain Gates told her and moved to stand in front of her desk. Gates continued to read the file in her hand for a few moments. Kate stood silently. Eyes down wondering exactly what Gates was going to stay, figuring it could not possibly be anything good. Castle was THE prime suspect in a murder investigation. And unlike the last couple of times they had arrested him; it actually looked like he had done this. Gates turned back, peering over her glasses at the Detective.

"I have been keeping up with the developments in this case," she stated, flicking papers in the file.

"Yes, Sir." Beckett replied, keeping her eyes down.

"It would seem there is a large amount of evidence against Mr Castle."

Beckett took a deep breath before looking up to her Captain and replying "Yes, Sir."

"Do you believe Mr Castle committed this crime?"

Kate startled, she had been expecting many things, but not this and was momentarily stunned into silence. She knew in her heart that Castle was not capable of committing this crime, but what she knew and what she could prove were two very different things at that moment.

"Sir?" she asked hesitantly, stalling.

"Detective Beckett it is a simple question, do you believe Richard Castle committed this crime?"

Kate paused to gather her thoughts and present them in the best possible way, hoping her voice would not betray her now.

"I think, as a Detective, it doesn't matter what I believe. Only what I can prove."

Captain Gates huffed and narrowed her eyes at the Detective. But Kate did not drop her gaze this time.

"The evidence is damming, Detective. Damming. And now it would appear that not only did Mr Castle have opportunity, he also had motive. But I repeat, again, my question; do you believe Richard Castle committed this crime?"

"No Sir," Kate replied "I don't think Castle did this. I know he is not capable of cold-blooded murder."

Gates ponder this for a moment. Kate knew Castle was innocent. It tore her up inside to know he was sitting in the interrogation room waiting for his lawyer, as her, their, colleagues built a case against him.

"Well then you have your work cut out for you don't you. Because you need to prove to yourself beyond a shadow of a doubt that he did this or prove to everyone else he didn't. Dismissed."

Kate walked out of the office stunned, Gates had just told her to keep looking. She had expected a speech more along the line of 'throw the book at him', but Gates didn't do that and for the first time in days a small smile crept onto Kate's face. She would keep looking. She would prove beyond a shadow of a doubt to everyone else that he didn't do it.

Okay, what do you think? This has a second part if people are interested.
