Title: Law and Authors

Summary: If you totally hate the idea of a Bones/Castle crossover… please for the sake of everything that is my sanity then back out now and quickly. With that said: This is a Bones/Castle crossover and if I have ever said anything of mine was AU out of the realm of possibility then this is even beyond that. Hahahaha go further than you can imagine I would go. The FBI gets called in on a case that Beckett and her team is working and of course the agent getting called in is none other than Seeley Booth because they need one thing he has, Temperance Brennan and her team. Beckett still does not like working with the FBI. How does Castle feel about them working with another writer? Well we shall see. Montgomery is still alive during this one and the squints make an appearance from distance only. Since everyone wants a Castle and Bones timeline I can't give a timeline for equal shows they started at different times and romances began in different seasons so separately lets say Castle let's give is an AU imaginary around Season 3 but Josh is out of her life and Gina is just a publisher. Bones let's say Season 4 AU imaginary no complications with either of them.

Disclaimer: I don't own anything to do with Bones or Castle but hey I know its January but I'll start asking now, my birthday is in May… I am not picky so either Nathan or David for a birthday gift would be great.

A/N: Still working on The Biggest Heart in the World….. don't worry there is a OMG you are not going there in the chapter coming up… but yes I'm going there. But I watched Castle and Bones today and I was like, yep I'm going there too.

Chapter One: Unique Situation

New York, Castle's Loft

Castle was standing in his kitchen starting on his first cup of coffee when his daughter came down the steps smiling. "So is today a writing day or a precinct day dad?"

He smiled at his daughter's question. "A writing day and I'm sure Beckett is thankful for that."

Martha's voice sounded behind him. "Sometimes I'm not so sure, I believe the beautiful Katherine has a bit of a crush on you Richard."

"You have no idea what you're talking about mother but just keep in your dream world, you want her for a daughter-in-law."

Just as he reached the office door the doorbell rang so Martha went to answer it. "Oh Katherine darling, we were just discussing you."

She smiled. "I hope it was something good Martha."

Alexis picked up her backpack and walked to the door. "Oh gram thinks you're in love with dad and dad says you're not. I'm heading to school so you children play nice now and I'll see you later." She laughed as she walked out the door.

Martha looked back at her son's red face. "Well what she said, I assume I'll see both of you for dinner this evening. I'll be home around 7:00 so one of you call me if you're going to be late, what do you think about Italian tonight Katherine?"

She looked over toward Martha. "That sounds great Martha but you got dinner last night so we can get dinner tonight."

Martha waved toward her son and then hugged the detective. "Then I'll see you later darling, bye Richard." And she was gone.

Kate closed the door then walked over to Castle and stopped right in front of him. "Want to tell me what just happened there?"

He walked into his office knowing she would follow him. "If I understood it then I would explain it to you. Alexis asked if I was writing or going to the precinct and I told her I was going to write, I was sure you would be thrilled. Then mother came down the steps telling me that you have a crush on me, and I told her she was wrong. That's when you rang the doorbell and the morning pretty much just went nuts."

She picked up his cup that was sitting on his desk and took a drink. "Well grab your shoes and jacket, we have a crime scene and I thought I would come to pick you up plus I left something here the other night."

"What did you leave here?"

She smiled and stepped into his bedroom with him behind her then walked into his closet unbuttoning her shirt. "I wanted to wear my blue shirt today and I realized I left it here when I changed into the t-shirt to be comfortable." She came out holding the shirt but was in her bra only and saw the way he was looking at her. "Really Castle, we're best friends I've seen you in only your boxers you can look at me in my bra. Now come on let's go."

Crime Scene

When Beckett and Castle got out of her car the guys and Lanie just looked at them but when she got to them Lanie looked at her friend and smiled. "So want to tell me why you and writer boy are arriving together in your car?"

Beckett looked at her and rolled her eyes. "Sure, I picked him up because I left my blue shirt at the loft the other night and I wanted to wear it today."

Lanie stopped working and looked right at her and spoke lower. "Do you want to tell me why you left a shirt at his place?"

Beckett shrugged. "No big deal, we were making pizza at the loft with Alexis and he thought I would be more comfortable in a t-shirt so I changed. I wore his shirt home and left my shirt there, he washed it and hung it in his closet then we both forgot about it. I wanted it this morning; I remembered where it was and went to get it." Then she looked at Lanie. "Really Lanie, we are not sleeping together but when we do I won't tell you about it that's private."

Lanie leaned in closer. "You didn't say if sweetie you said when."

"I know I did, and that's what I meant to say. Everyone knows that best friends make the best lovers and he is my best male friend, I might want to test the theory and well his kisses are amazing. You'll have to trust me on that, not test it."

Lanie looked around. "So where is writer boy anyway? And how do you know about his kisses?"

"None of your business and he said something about running to the coffee shop; he poured coffee this morning and only got one drink before I finished it. He'll be here soon." She pointed down. "So what do we have?"

"A big complication is what we have so Esposito is calling Montgomery to see what we need to do. We have our victim from last night but we have our victim on top of a couple more victims from other times and maybe not even from here."

"Oh no, they are not calling in the FBI."

"I told Esposito to please request no Sorenson considering the first thing he'll do is send Castle home."

"He can't send Castle home, this is my case and no one sends my partner home. I refuse to work with anyone that won't work with my partner so he can forget me working with any FBI stiff."

Ryan walked over. "Sorry Beckett it looks like you have no choice, everything gets wrapped up and hauled to the morgue. We do our thing here and Montgomery is calling Washington D.C. to tell them we need someone outside of our own field office. He said he would explain your unique situation with your civilian investigator partner and see if they have an agent that will agree to work with us."

Ryan saw her look over his shoulder and smile so he looked behind him and saw who she was looking at. Castle was standing there with two coffees and he was talking to an officer, then he started walking toward her so she walked toward him. "Hey Castle, looks like they're bringing the FBI in on this one." Ryan and Esposito were standing behind them in hearing range.

"I understand Beckett; you have to do your job just call me or stop by and keep me in the loop if you don't mind. You know mother and Alexis would miss you if you stop coming over for dinner at night."

"Esposito requested an agent that would agree to work with my civilian investigator partner, I'm sure they can find at least one that understands my situation."

He smiled. "And what situation is that?"

"I'm addicted to coffee and I have a trained writer that will bring me some." She winked at him and then turned to the guys. "So what's our next move while we wait for some FBI agent that will want to kick out my caffeine enabler?"

Washington D.C.

Temperance Brennan looked up from her desk when she heard his voice at her door, Agent Booth. "Hey Bones, the FBI needs a big favor from us and a really big one from you."

"That sounds like you're saying I have no choice."

"Well they need us to go out of town on a case and it's a special case, I need to discuss it with Cam and the squints so let's go out here."

She nodded and joined him where Cam had gathered everyone together. Cam started briefing everyone. "So there is a case in New York, the FBI is sending Agent Booth and Dr. Brennan then we will be consulting with not only them but a team from New York. That team will consist of NYPD plus their ME."

Angela spoke up. "Why are they sending Booth and Brennan to New York to work with NYPD?"

Booth jumped in. "They have a victim found this morning that is a recent victim, their ME will take care of that one unless we're needed. But under that victim they found three open body bags and two of them were tagged from Washington DC which means stolen bodies from a morgue and the other from New York but not from their morgue. The bodies are months old and no tags on the bodies and that means we have our work cut out for us. So they had to send someone from D.C. and of course they needed a bones person. Logical choice would be the agent that's a bones person."

Hodgins smiled. "So that means I'm going to get special delivery dirt and bugs, right Booth?"

Angela laughed. "Down boy, Booth you have really made his day on this one."

Bones started walking toward her office with Booth following her. "So when we get packed and headed to the airport are you going to tell me the real reason they're sending us?"

He smiled. "Yes, I'll tell you the real reason I actually volunteered us for this one."

Booth's SVU, airport bound

"So Bones I did some checking on the NYPD we'll be working with, Detective Beckett's mother was murdered when she was a teenager. She always refused a partner but she does work with a civilian investigator that's a writer, I mean he's not like you but he writes books based on her. She refers to him as her partner but I guess others in law enforcement want to kick him out first thing because he's a civilian and well they needed someone that understands their situation."

She nodded and smiled. "You understand because of our situation, me being your partner and all."

"You're my best friend Bones and if I'm not too far off I'm betting that he's her best friend. When you have a job like ours you need that someone that you can talk to, someone to trust. I bet he's that someone for her and I hate that she feels she can't trust the FBI for that reason. Anyway on Detective Beckett's team there are two other detective's two guys Kevin Ryan and Javier Esposito who are partners. Then the ME they work with most of the time is Dr. Lanie Parish. The commanding officer is Captain Roy Montgomery, Caroline talked to him and he said to tell us thank you for agreeing to come. We meet with them at the precinct first thing in the morning."

They pulled into the parking lot of the airport and he headed for short term parking. "Why are you parking in short term parking Booth?"

"Daisy and Sweets are picking up my SVU later tonight and taking it to my place so I don't have to leave it at the airport while we're there. I mean we don't know how long we'll be gone."

Booth and Brennan, New York… much later in the evening

She smiled at him outside her hotel room door. "Thanks for dinner Booth."

"You're welcome Bones. So I'll be out here around 7:00 in the morning?"

She laughed as she grabbed his hand and put a key card in it. "Let yourself in when you get here I mean we have keys to each other's homes why should on the road be any different? Goodnight Booth." She rose up and kissed him on the cheek. Then let herself in smiling at him again over her shoulder before closing her door.

Castle's Loft, late the same evening

Castle and Alexis were cleaning up the kitchen after they had once again banned Kate from helping and Martha had joined Kate at the counter with a glass of wine. Alexis looked over at Kate. "So the FBI agent from D.C. will be here tomorrow morning?"

"Well Montgomery said that they were arriving tonight but they would be at the precinct in the morning, I guess they're sending two agents. I'm not looking forward to it, the first thing they always do is send Castle home."

He stopped what he was doing and looked at her. "I told you Beckett, you have a job to do and that case looks intense. If they say I'm in the way then I'll come home and I'll sneak you coffee to the precinct, we can talk on the phone or whatever. Just come over for dinner, I don't want to interfere in your job and if you miss me you can always just sleepover."

Alexis frowned and punched him in the arm. "Excuse me; teen daughter is in the room."

Kate laughed. "I guess we'll have to wait and see what happens tomorrow."

Martha hugged Kate to her side. "I'm sure most law enforcement people don't understand your unique position, I'm sure you're the only one that has a writer partner."

Kate stood up and started putting on her jacket. "Well whatever happens they need to understand, my partner stays. So Castle, I'll pick you up at 7:00 in the morning?"

He started walking toward her. "Actually I need to run an errand in the morning then I'll stop for your coffee, I'll meet you at the precinct if that's okay?"

She smiled when they got to the door. "They'll be there around 8:00 so don't be much later than that so the agents don't have a reason to think my partner is a slacker and kick you out."

"I promise quick errand and my partner's caffeine fix then no later than 8:05."

She pulled him by his shirt to her lips for a quick kiss. "See you in the morning Castle." She waved back at the ladies. "See both of you tomorrow night." Then she closed the door on her way out.

He turned around and looked at them. "What are you looking at?"

Martha smiled. "She's here for dinner every night, picks you up most mornings, refuses to work with anyone that won't work with you and kisses you goodnight on the lips. You my boy are in some serious denial get on with seducing that girl and make me some more grandchildren while I'm young enough to remember their names."

Alexis headed for the steps. "Okay teen daughter is now leaving the room, goodnight both of you."
