Hi guys, sorry for the wait. Now most of this chapter was written at 3:00 this morning after I woke up to find my best friend had her baby 15 weeks early and he will be touch and go for 2 months and couldn't go back to sleep. So please excuse any silly mistakes written, I was tired when I wrote the first half and pretty much shattered when I wrote the second half. This is not where I expected the story to go yet but it did take on a life of its own.

Chapter 4

On the way back to the precinct, Castle and Beckett were in the car together while Ryan and Esposito were in the car behind. Rick sat in the back continuously sneaking glances at the detective sitting in the front seat occasionally seeing her casually look at him through the rear view mirror causing him to smile.

A lot of looks were shared between the two ex lovers but not one word was spoken. The drive from the club to the 12th was silent; she had never seen him like this.

In the car behind the boys were dumbstruck as to what had just happened. Did Beckett offer to take a suspect in the back of her crown vic without backup?

"What do you think is happening with Becks?" The Hispanic detective asked looking from his position in the driver's seat to his partner briefly.

"I dunno, she was acting a little weird at the party before" came the reply from Ryan a moment later.

"Yea, it's as if they all know each other from something in the past" "Dude, they definitely know each other. But as to how deep it goes, I don't know, but we need to find out"

Making a silent pact and a vocalised bet, $20 going to Ryan if they've slept together but $20 going to Espo if they were close to marriage, they had to find out what was going on… "Lanie!" they both said in unison

They all arrived back at the 12th, Kate, Ryan and Esposito all went back to look at the murder board while Castle was getting booked and hauled into the interrogation room by the officers.

"He's ready when you are Detective Beckett" called one of the booking officers from the hall.

Beckett looked at her boys and walked towards the interview room. The boys gave a 'this will be interesting' look to one another and got up to watch through the one way mirror.

Kate walked into the interrogation room and Castle suddenly became much more alert.

"Hi, Kate" He said with a smile but she wanted to keep this professional. "Mr. Castle, you've been informed of your rights?" putting the Tisdale file on the table between them.

Castle nodded "You look good" he smiled at her again. She couldn't stop herself from smiling "You look good too" then BAM, right back into professional mode "for murder." Sitting down and taking out 4 different photos out of the folder.

"Do you know this girl?" "She's pretty" "She's dead, found like this" holding up the photo of Tisdale's murder scene "Flowers from your grave" he mumbled as he grabbed the picture. "Do you know her, maybe you met her at a book signing or club?" trying to beat around the bush she didn't ask the question she really wanted the answer to but he called her on it

"Could've done, I meet lots of pretty girls but she's not in my little black book because I know your curious" her cheeks were now tinted a shade of pink. Kate quickly changed the subject to hide her embarrassment "What about Mr. Fisk? Small claims lawyer" flashing him a photo of the victim Kate watched Rick look down at the photo then back to her grinning "most of my claims tend to be on the larger side" "he was found like this" flashing another photo to Castle "right out of Hell hath no fury" she continued. "Looks like I have a fan" looking towards Kate grinning "Yea, a really deranged fan" she retorted quickly "You don't look deranged."

Kate was confused by this statement and shot him a look "Oh come on Kate…" She cut him of "It's Detective Beckett" "Angry wickens out for blood, only hard core Castle groupies read that one…. Kate" he continued as if she hadn't even spoken.

Giving her one of his very charming and irresistible smiles again and she went a shade of pink, reaching over to grab her hand without her noticing he took hold of it and softened his voice to a whisper only audible to her

"Good to see your still reading all of my books, baby."

The boys in the observation room couldn't believe what they were seeing, Richard Castle was playing with fire, and Beckett didn't seem to care.

As the interview came to a close, the boys decided to scatter, before they were caught.

On the other side of the glass, Beckett pulled her hand out of Castle's grip, got up and started to walk towards the door "You're free to go, Mr. Castle." Getting up and quickly walking behind her to put his hand up against the door to stop her from leaving. Beckett didn't realise how close he was until she whipped around to scold him and he was a few inches away. Backing away from Castle, Kate thought 'shit' as she hit the door. With his hand on one side of her and the wall on the other Beckett was trapped.

Castle grinned when he saw the panicked look appear on her face when she saw that he was getting as close as possible. He put both hands against the door, leaned in as close as possible without actually touching her and whispering in her ear "What if I don't want to go right now? What is I want to stay right here with you, my beautiful Katherine?" Castle took the lobe of her ear in his mouth then moved down the spot on her neck that knew drove her crazy.

Kate was getting nervous watching him lean in towards her but not grab for her. Then she felt him seductively whisper making her go weak in the knees. Kate thought she was doing well resisting his seductive ways until he sucked on her ear and placed open mouth kisses on her weak spot, that was the final straw as she let out a moan.

"Rick…" she voice a little breathy as she was trying to resist him. Unintentionally, Kate moved her hips forward to meet and grind against his. One thought going through her mind, 'damn he was always got at this, he knows all the right buttons to press'.

"Rick…" she said again, her voice still weak and breathy. She heard him let out a groan as her breath blew across his ear and he ground his hips against her even harder. Coming out of her day dream and realising what they were doing and where they were doing it, Kate saw his distraction as an opening and took it. Castle was so preoccupied he didn't even realise that she was no longer pressed against the door but she was pressing him against the wall.

Kate put her hands on his cheeks pulling his head from his place on her neck and planting a kiss on his lips so that he would focus on her face and what she was saying "You have just been outsmarted" she stated with a coy smile on her face. "We are not going there again Castle and even if we were here is not the right place. Go Home, Rick…" Looking down to his now very alert groin and scraping a nail across his dress pants bringing out another growl "but first, fix yourself up" and with that Beckett walked out the door smiling to herself and 'damn he is so hot' going through her mind.
