Kate made her way back into the elevator in a daze. So much had happened in the last twelve hours and this really was just was the final bullet to the gun.

The detective now new for certain there is no coincidence in this case. She is the intended target and again an innocent life had been taken in her name. Literally. As the elevator dinged, Kate exited. As she maneuverer herself to her desk she was still in the state of shock. She couldn't think straight. What had she done now? She had stopped digging in her mother's case. There was no Nikki Heat reference this time, thank god. Maybe it was someone she put away? However the creepiest thing of all was how the last sentence ended KC. Whoever this person was new who she was married to and was looking to not only expose her - but kill her.

"Hey Beckett? You alright?" Esposito called from his desk. Obviously she had not done as good of a job as she thought of concealing her emotions. Beckett smiled lightly and responded with a nod. She was slowly regaining coherent thought. Murder to solve – need to get to work.

Kate got up from her desk and took the profile picture from Katherine Bennets file and placed it on the murder board along with her details. Ryan and Castle the emerged from the conference room and made their way over to her with defeated expressions. Obviously the CCTV was a bust, Kate thought.

"Nothing Boss." Ryan said as he approached them. "Nothing. No one out of the ordinary entering the building in the last week. Oh – this our Vic?" He sparked up with the idea of having a lead.

"Yeah, Katherine Bennet. 29. No priors. Kindergarten teacher." Beckett read out with absolutely no emotion in her voice. This immediately was noticed by her husband as he subconsciously took a step closer to her. He purposely brushed her shoulder as he leaned beside her on her desk. Kate smiled softly at his always attentive and observant natural behaviour. It was his subtle way of telling her he knew something was wrong and was here for her no matter what.

"Great, want me to run her down? Contact the family?" Esposito said from her left having heard the whole conversation.

"Yeah do that. But before you do there is something else you guys need to see." That said Kate walked around her desk and picked up the photograph of the writing on the victim.

"This was written on the victim's body."

Castle looked at the note with a worried interest and read out loud "MY NAME IS KB. I WILL BE THE FIRST TO DIE. WHO WILL BE NEXT? COME AND CATCH ME KC. Kate what is this?"

"I have no idea." She said and glanced at him he looked sick with worry and she just wanted to kiss it away.

"Boss is this guy targeting you? And what do they mean KC?" Esposito questioned with anger and confusion.

Ryan suddenly had a look of realisation on his face "Beckett…"

"Yeah I know Ryan. Look just get everything you can on Katherine Bennet, I want to speak to next of kin as soon as possible. I am going to talk to the Capt. Castle with me."

Kate knocked on Montgomery's office door and heard a faint "come in". Once they had entered the room Montgomery noticed the worried looks on both of their faces. "What's going on Beckett?"

"Sir, we have identified the victim," Kate started as she handed over the file, "there was a message on the body sir," Kate took a deep breath and then stated "directed at me."

The captain immediately understood as he took out the photo of the victim's body and the killers' message.

"KC" He whispered to himself but loud enough that the pair heard him.

"Yeah whoever this is knows where married and I think is looking to expose us." Becket said as she started to pace the room. "Sir I think we need to tell the boys if we don't, we can't carry out this investigation properly."

"I agree detective, but I am calling in the feds on this one. You're too close. So is your team. If this person keeps good on their promise there are going to be more bodies."

"But Sir we are perfectly capable-"

"Enough Detective," he cut Becket off with a strong authority, "that's an order, you are no longer lead on this case. I am not kicking you off the investigation, but if you can't control yourself or it gets way too close to home I will. I will call the FBI and they will be here by tomorrow morning. In the meantime I think it's best if you go home and get some rest." He dismissed. They sore this as their cue to leave; there was no messing with the captain tonight. Just as they reached the door, the captain spoke up again. "Oh and Beckett? Inform those boys tonight, they're going to need a few hours to process this; God knows I did."

Kate slightly smirked "Yes, Sir."

Castle exited right behind his wife out of the captain's office. "So how are we going to do this? Do we just blurt it out or do we ease in to it or do we have some fun with it? I vote the last one!" He whispered discreetly in her ear in a very castle way. Kate smiled and tried to hold back her laughter.

"Castle we have been married for four years and have managed to keep it a secret from our best friends and you want to blurt? No way we owe them a bit more than that." And with that she turned and walked towards where Ryan and Esposito where standing having coffee outside the break room. "Hey boys, Castle wants to have us over tonight to discuss something important."

"What is it? Is something wrong? "Esposito immediately questioned as Ryan stayed quiet.

"No, no. there is just something w- he needs to discuss with us." Kate only just caught herself on her slip. Thank god the secret would soon be out, she didn't know how long she could keep this up.

"Okay, what time? I think I have plans with Lanie tonight though." Esposito said worrying suddenly what Lanie would do if he cancelled their date.

"It's alright Esposito she needs to be there as well, oh and you can bring Jenny if you want Ryan." Castle chimed in as he came up behind his wife. "Now if you will excuse us we have some business to attend to, see you at seven." And with that he pulled Beckett by the arm and back over to her desk.

"Get your coat my dear because we are getting out of here so I can kiss you senseless," he whispered lustfully in his wife's ear. And to his surprise she immediately grabbed her coat and bag and walked quickly with him to the elevator.

As soon as they were safely inside the elevator Rick had Kate pressed up against the wall and his mouth over hers before you could say "the butler did it".

Suddenly there was no more worrying, no more killers, and no more impending death. Just them. Husband and wife and while they had a dangerous road ahead, they knew they would be fine as long as they had each other.

Well that is as long as they survive the wrath that is Lanie Parish.
