My first crossover so i hope its good. I love both shows and finally decided I wanted to try something knew. It's mainly going to be in DiNozzo's POV but i will add in others as well. it all depends on if you like it.

Okay, here it goes.

"Wait a minute; did you just say what I think you said?" Castle asked as he walked up to the three detectives.

"Depends, what did you think I said?" Kate asked. Both of the boys turned to face Castle who was carrying two cups of coffee, one for him and one for Kate. He handed Kate hers and got head shakes and evil glares from the guys.

"That NCIS will be coming here, to New York."

"Yes you heard me right." Kate said as sort of a sigh. "Promise me you will be on your best behavior."

"I promise, when are they coming?" He asked. He had heard many stories about one particular NCIS agent and he hoped that he would be coming. Ryan looked at his watch then up at Castle.

"They should be flying out in a couple hours."

….

"New York? Really?" Tony was looking at Gibbs hopefully.

"Jeeze you act like it is Disney Land." Ziva said coming up behind him, startling him. One day he will be the one who startles her, he just has to learn to be sneakier than her first.

"Get your bags; we fly out in an hour." Gibbs said and then started typing something on his computer.

"Do you know why I act like it is Disney Land Ziva?" He asked and she shook her head while rolling her eyes. "Because young grasshopper, New York has everything. The clubs, the restaurants, the sights, the girls…" He trailed off, getting lost in thought.

"Wait; did you just say New York?" McGee asked as he sat his stuff down at his desk. He looked just as excited as Tony and Ziva shook her head.

"Yes, yes I did." Tony said.

"Which precinct will we be at boss?" McGee asked Gibbs.

"Uh…" Gibbs searched through a couple papers. "The twelfth with Captain Montgomery and Detectives Kate Be…" He didn't get to finish before McGee jumped in.

"Beckett, Esposito and Ryan." He looked even more excited now.

"Do you know them Probie?" Tony asked.

"I know of them, Richard Castle works with them."

"Wait a minute, Richard Castle the author?" This had sparked some interest in Ziva.

"Yeah."

"I enjoyed his last book, Naked Heat." Ziva said.

"Naked Heat?" Tony asked, the title being the only real thing that sparked his interest in this conversation.

"The lead characters name is Nikki Heat and she is based off of Detective Beckett." McGee explained.

"Do you by any chance have this book?" Tony asked.

"Yes." McGee raised an eyebrow at him.

"Can I borrow it?"

"Since when do you read Tony?" Ziva joked.

"You'll want to start with Heat Wave first." McGee went over to his desk and sifted through a drawer. He handed Tony the book and a smile spread across his face.

"This is a great cover." He said and Gibbs gave him a head slap.

…..

"What page are you on?" Ziva asked leaning over Tony's shoulder. He glanced at her and tensed at how close she was. She did this to him often and every time it had the same affect. He took a deep breath and tried to focus but the scent of her made that hard.

"I'm on eighty four, why?" He asked trying to focus on the book.

"You'll see." She said with a sly grin before walking away to the back of the plane. He watched her until she was out of sight. He glanced over at McGee who also had a smile on his face.

"What?" Tony asked and McGee shook his head and looked back down at his magazine. Tony kept reading hoping whatever Ziva was talking about would come up soon. Tony had reached page ninety two when Gibbs announced they would be landing shortly. He closed the book and tucked it away with his things. "I really hope this Detective Beckett is as interesting as Nikki Heat." Tony said with a smile.

"What page did you make it to?" Ziva asked.

"Ninety two, again, why?" He didn't like that she knew something he didn't. It didn't help that McGee knew as well.

"Just wait." She had that same sly smile on her face again.

….

"Agent Gibbs just called me; they landed and should be here shortly." Kate said walking up to the guys who were all plastered in front of the murder board. Castle turned to face her, his eyes wide.

"Agent Gibbs?" She nodded. She just said that. "As in the Agent Gibbs?"

"Sure, why not." Kate said plopping down next to Esposito. She had no idea what Castle was so excited about.

"Are the other agents names Tony DiNozzo, Ziva David and Timothy McGee?" He asked hopefully.

"I think so, why?" Kate raised an eyebrow at Castle who was now standing in front of the murder board.

"Because Agent McGee is Thom E. Gemcity." He looked at them and his excited face quickly faded. "Come on, seriously? Don't you guys read anything but my work?" He half joked. Kate thought about it for a moment. The name sounded familiar. "He wrote DEEP SIX. He actually based it on his fellow Agents."

"Oh, okay." Esposito nodded even though you could tell he had no idea what Castle was talking about.

"It will be great to be able to work with another writer." Castle said happily.

"How many agents are coming?" Ryan asked. Kate thought about it a moment.

"Four but they are also bringing their Medical examiner, Gibbs called him Ducky." Kate said and Ryan smiled.

"But we have Lanie." Esposito said. Kate made a mental note to ask Lanie about him later.

"I told them that. They wanted to bring him." Kate shrugged. She had already talked to Lanie about it.

…

Tony was now wildly flipping the pages of Heat Wave. He knew that soon he would have to put the book down and work but he also knew what was coming. Tequila could only lead to one thing and he knew it was coming up soon. Sadly, the car came to a stop at the precinct while he was on page one hundred one. He shut the book again and tucked it away. Ziva was sitting next to him with that same sly smile. She had been reading over his shoulder for a couple blocks now. He never looked up to see her but he could feel her breath on his neck. It had taken everything he had in him to stop himself from doing something he really shouldn't do, no matter how bad he wanted to.

They quickly entered the building, only stopping to find out what floor homicide was on. Gibbs was eager to get started. Personally, Tony would have rather headed to the hotel first to relax and finish this book. They all gathered on the elevator and slowly rode up. The elevator stopped and they hurried off. That's when Tony saw her, a woman who matched the description of Nikki Heat perfectly. She saw them and held out her hand to Gibbs.

"Agent Gibbs?" She raised an eyebrow and Tony found it very sexy. Gibbs nodded and took her hand. "I'm Detective Kate Beckett; these are detectives Kevin Ryan and Javier Esposito." She gestured to two of the men next to her, the third he knew from the back of the book. "…and this is Richard Castle." Tony could tell she was hiding something when she said his name. He wondered if their relationship was anything like Jameson and Nikki's. He found himself hoping otherwise.

Gibbs shook all of their hands before introducing them. "These are agents Tony DiNozzo, Ziva David, Timothy McGee, and this is Doctor Donald Mallard." He gestured to them all. Tony politely shook her hand before shaking the others.

"Richard Castle I'm so pleased to meet you." Ziva said while shaking the man's hand. Tony felt something stir inside him but quickly pushed it aside.

"Like wise." He said with a smile. Then it was McGee's turn to shake his hand.

"It's great to meet you. I love your work." He said sounding like a school girl with a crush but trying to hide it. Then something happened that Tony had not expected.

"I like your work as well. I must say that I am looking forward to working on a case with another writer."

"You've read my book?" McGee seemed surprised. He nodded. Then a man came out of his office.

"Hello I'm Captain Montgomery." He said shaking each of their hands. "Thank you for coming down. If you need anything let me know."

"Thanks." Gibbs said and then the man disappeared back into his office.

"Now that everybody knows everybody let's get started." Detective Beckett said. They followed her into a small room where a murder board had been set up. She briefed them on the case. Danielle Moore, thirty eight, was a Marine for thirteen years. Jeff Sanders, forty, was a Marine for fifteen years.

"How about we divide the troops?" She asked when she was done briefing them.

"Sounds good to me." Gibbs said. "McGee with me, we'll go with Detective's Ryan and Esposito if you don't mind." Gibbs said. Tony smiled to himself, happy that he would get to be with Beckett.

"Okay. You guys take them to the latest crime scene." Beckett said.

"When do I get to see the bodies?" Ducky spoke up after being silent the entire time.

"Will you guys run Doctor Mallard by the Medical Examiners?"

"Yeah, no problem." Esposito said.

"Please, call me Ducky." He said before they all disappeared. This left him with Ziva, Beckett and Rick.

This should be fun.

He wasn't looking forward to seeing Ziva flirt with the author all day. They gathered their stuff and headed for the latest Vic's apartment.
