Title: The Bones in Vegas

Rating: K+

Disclaimer: I own neither CSI or Bones, I'm just borrowing them, and I promise to give them back when I am done.

Spoilers: This is set before the Miniature Killer episodes on CSI, and before the Sully episodes of Bones. It references The Woman in the Sand from Bones for obvious reasons.

Author's Note: I've wanted to write a CSI/Bones crossover for awhile, but up until now I have not had a good enough plot. So finally, my muse has smacked me upside the head with this story, and here it is. Enjoy!

Las Vegas

A cloud of dirt and sand filled the air as the backhoe dropped another load onto the pile. The sounds of construction filled the new development area as lots were dug and the skeletons of houses began to form in others. Another piece of desert in Vegas was being claimed to be transformed into a suburb.

A supervisor walked by the growing pile of dirt, casually glancing at it and the backhoe. But as his eyes wandered over it, a flash of white caught his gaze. He walked back to the spot and his eyes grew wide, and he suddenly motioned for the machine's operator to stop, frantically waving his arms.

Flood lights illuminated the dirt pile and hole, surrounded now by police tape. Gil Grissom leaned down to cross under the tape followed by Sara Sidle. He let his flashlight sweep the area and found what he was looking for. A collection of bones lay in front of him, next to the dead body of a woman. With a gloved hand he rifled through the bones, then turned back to the corpse.

"Any ID on the victim?"

"Not yet. Construction crew dug this up by accident. There's no record of the area ever being used as a cemetery either," Jim Brass said as he joined his colleagues.

"One body, two skulls and various other bones," Sara observed as she walked the perimeter, "I'm going to take a long shot and say this was a body dump site," she dead panned.

"Impromptu burial suggests murder," Brass added.

"A pickaxe, and a spade, a spade, for and a shrouding sheet: O, a pit of clay for to be made for such a guest to meet," Grissom quoted.

Brass raised an eyebrow at him.

"Hamlet, act five, scene one," the night shift supervisor replied.

Washington, D.C.

Booth jogged up the stairs of the platform, his face covered in a huge grin. He spotted her examining a skeleton.

"Roxie honey! Have I got a treat for you," he drawled in his New Jersey accent.

Her head snapped up and she raised an eyebrow at him, "Aw Tony, can't you see I'm busy now. This better be good," she fell into the act none the less.

He flashed her his charm smile and a pair of airline tickets, "We're going back to Sin City baby!"

By this time the rest of the squints were watching the act, all very amused and confused at what was going on.

"Is the Tiger hungry for another fight?" Brennan continued as Roxie.

"Nah, I'm tired of that scene, but who knows, we might encounter the mob this time," he replied, handing her the file.

"Okay, what is going on?" Angela exclaimed through a smile.

"When we were in Vegas on that underground fighting case, Bones and I went undercover. She told you right?" Booth answered, back to his normal self.

Angela turned to her best friend, "You told me something about Roxie and Tony but never about this whole act. Or how hot it sounds," her eyes flickered between the pair.

"It was fun," Brennan muttered as she continued to read, "Booth, besides this case being in Vegas, what does it have to do with us? If there's a body, why am I going?"

"Well, the body was a tourist, who belonged to this city, therefore belonging to my missing persons case. Said body was found buried amongst two sets of skeletal remains, thus bringing you into the picture."

"Hey, I don't care what the excuse is. I'd take a free trip to Vegas," Hodgins said.

"You know, I've never actually been to Vegas, I don't see the need," Zack mused.

Angela rolled her eyes, "It's Sin City, what other excuse do you need?"

"So we'll go, collect the bones and send them back then," Brennan said, working out the situation in her head.

"Nope, not this time Bones. Sorry guys," he added to the squints, "We'll be working with the local CSI team, they were first on the scene to begin with."

"I'd prefer to work with my own team Booth."
"Well so would the supervisor out there, a Dr. Gil Grissom," Booth read the file.

Hodgins' jaw dropped, "Gil Grissom! Thee Gil Grissom! No way, I am so coming!"

"Who's Gil Grissom?" Angela asked.

"Only one of the top entomologists in the country! He's written some amazing stuff about blow flies and crime scenes to say the least," Hodgins rambled.

"I've heard of him too," Brennan added, "Apparently his crime lab is number one in the country, that is, if you don't count our institution."

"Well then it's settled. You and I are off to Vegas, so go get your stuff," Booth told Bones, beginning to escort her off the platform.

"Wait, don't I get to come?" Hodgins called after them.

"Sorry, not this time," Booth said over his shoulder.

"I never get to go anywhere," Hodgins pouted.

"What about the pirates case? You got to go diving," Angela reminded him.

"Someone almost killed me, so that doesn't count."

"But you have fun here, you know, experiments with Spam and sea monkeys, or with wood chippers, even explosives."

A grin spread across his face as he remembered, "Yeah, I guess I do have a good time here. Hey Zack, I have an idea," he called to his partner in crime.

Angela cleared her throat, "I think we have fun doing other things here too," she raised an eyebrow at him.

He got the message, "And I've had some very good times with you," he replied wickedly.

Las Vegas

The CSI team assembled in the break room, milling over coffee and gossip.

"So what's the deal with the dead tourist?" Catherine was asking Sara.

"The vic was identified as Lisa Rogers from Washington D.C, been missing for several weeks now."

"And the bones?"
"We're not sure who they are yet."

"And the meeting Grissom called?"
"Concerns the vic and the inclusion of authorities from Washington on the case, as far as I know."

At that moment the supervisor in question came into the room, bringing silence to his team.

"I have an announcement to make concerning our latest case. As you know, our vic is a missing person from Washington, where the local chapter of the FBI was working on her disappearance. They have informed me that they are sending an agent to take part in our investigation," he didn't hide the slight distaste in his voice. It was a well known fact that Gil Grissom liked to have control of his cases and didn't like sharing with the feds.

"The agent is also bringing his partner, a renowned forensic anthropologist to work on the bones we found. We will be sharing the lab and details of the case with them, so I expect you to show them the same respect you show any other law official."

"When will they be here?" Warrick questioned.

"Within the next few hours."

Booth drove the rental car through the streets of Vegas as Brennan went over the case files again.

"How come you didn't let me drive?" she bugged Booth.

"Because you drove last time."
"Last time we were here? I did not."

"Well you drove on the last case. Besides, I always drive."

She rolled her eyes at him, "Tell me again about our victim," she changed the topic.

"Lisa Rogers, age twenty five, went to Las Vegas three weeks ago and never came home."

"Was she a tourist? Who did she go with?"
"She didn't go with anyone. Her parents said she was going to audition as a dancer for a few shows, it was a dream of hers. She was supposed to go down for the week, audition, take in the sights and come home. Instead, she doesn't, parents call the cops, the case gets handed to me, and now she turns up dead."

"Did you talk to who she was supposed to audition for?"
"Yes. Lisa went to her auditions, they really liked her. When they called for a final interview, she was gone."

"Did she have a habit of taking off?"

"No, parents said she was predictable. Lived at home after graduating from school, and she lived to dance, never missed a practise."

"Did the crime lab send you anything else on the bones they found?"

"No. The coroner was going to start on them but when they heard you were coming, they stopped. Figured they'd let you do the work, being the expert and all."

Booth pulled the car into a parking lot, "We're here," he told Brennan.

At the front desk they identified themselves and were directed to the supervisor's office. Once there, Booth knocked on the door, "Mr. Grissom?" he called.

The night shift supervisor raised his head from his lap top and gestured for them to come in.

"You must be the agent from Washington," he replied, standing up to shake Booth's hand.

"I'm Agent Booth, and this is my partner, Dr. Brennan with the Jeffersonian in Washington."

Grissom shook her hand, "Dr. Brennan, it's a pleasure to meet you, I've read some of your work, it's impressive."

"Likewise Dr. Grissom. One of my lab techs back home is a fan of your work in entomology."

"Come, I'll show you to our evidence room and we can discuss the case further," the older man gestured towards the door.

Crime scene photos were laid out in the evidence room along with the victim's clothing. Sara and Catherine were pouring over the evidence trying to make sense of it.

"Sara, Cath, I'd like you to meet the people assigned to this case from Washington. This is Agent Booth and Dr. Brennan," he gestured to their guests who shook hands with the CSI's.

After exchanging greetings Grissom turned to his colleagues, "Can you get these two up to speed for me?"

"Sure," Catherine nodded, "The victims were found at a construction site, buried under what would be a new lot. Two sets of bones and one body were found."
"Complete skeletons?" Brennan asked.

"Not sure, Doc Robbins was working on that, but I think he's waiting for you."

Brennan had a confused look on her face.

"Doc Robbins is our coroner," Sara supplied.

"We identified the vic as Lisa Rogers based on a NCIC search, which put us in touch with Agent Booth," continued Catherine.
"Cause of death?" Booth questioned.

"Raped, strangled and dumped is what the evidence says."

"How long was she at the dump site?" Booth said.

"She's been missing what, three weeks? I'd say at least two."

"Her clothes were ripped, as you can see," Sara indicated to the evidence table, "And that's all she had, no personal affects, no purse, no ID. We have no prints, no semen, just ligature marks right now to work with."

"Foot prints?" Booth tried.

"A few, but we're still ruling out the work boots worn by the construction workers. PD is also working on the guys themselves, getting alibis and such," Sara answered, then turned to Brennan, "We're hoping you'll find more evidence on the bones."

"I'll see what I can do. Dr. Grissom, will you show me to them?"

He nodded and she followed him out of the room with Booth on her heels.

Part of the way down the hall they ran into Nick Stokes whom Grissom stopped and introduced Booth and Brennan too.

"I know you! I love your novels," Nick gushed, paying no attention to Booth.

"Thank you," Brennan replied.

"Your books are great, and some of the cases even rival the weird ones I've worked here."

"Really?"

"Really! I had this one case where we found a scuba diver in a tree and no water within miles of him. Or this time that this girl drowned in the middle of the desert-"

"We've had some odd cases too, right Bones?" Booth cut in, "Remember that one where we found that guy in the fall out shelter or when you found that girl in the wall at that club?"

"Or how about the one we're working," Grissom stopped the conversation.

"Well it was nice to meet you," Nick said a little awkwardly as he walked away, his eyes never leaving Brennan's.

Booth lay a protective hand on her lower back while he sent a warning glare back at the over eager Texan.

Once Grissom had introduced his guests to Doc Robbins, he left them in the morgue so that Brennan could do her work. Robbins had laid the bones out on autopsy tables for her and she looked them over.

"Booth, I'm going to need awhile to assess these bones. I'm sure I'll be alright with Dr. Robbins if you want to go and work another aspect of the case for awhile."

"Have you been to Vegas before Agent Booth?" the coroner asked.

"Several times actually," the agent replied.

"Was luck good to you in the past?" Doc Robbins winked.

"Booth's a degenerate gambler, he's not allowed to go to the casinos," Brennan answered bluntly to her partner's surprise, not even looking up from the bone she was examining.

"Bones!" he exclaimed, "We've talked about this before. I am not a degenerate, and I'm a recovered gambler," he said, becoming rather flustered.

"That still doesn't change your history."

He sighed, "Can't we just leave that alone? I don't bug you about your, um," he fumbled for the words as she raised an eyebrow at him.

"My what Booth?"
"That you're a work-a-holic."

"I don't know what that means but if you're implying that I like my job then you would be right, therefore you can't bug me about that."

Doc Robbins chuckled, "And how long have you two been together?"

It was Brennan's turn to be slightly embarrassed, "We're not together."

"No, just partners," Booth added, "You know, I think I'll go back upstairs now."
