I big puffy heart all of you guys that have reviewed this story so far. You guys really rock!

Rageoffire- Yes, the rating will probably change to T as the story goes. I wanted to start it as a K but as it's going, it's definitely looking like a nice T.

Also, I didn't know Cullen's secretary's name, or if he even has one (I'm sure he does) so I just went with what my fingers came up with. :)

Anyway, on to the story….

"Agent Booth, Dr. Brennan," Cullen's secretary smiled her greeting to them as they walked into the bright waiting room outside of his office.

"Hey Darlene," Booth said, ushering Brennan in with a hand on the small of her back.

"Go ahead and take a seat. His last meeting is running a bit over, he's still in there with them." Darlene continued to smile, gesturing to the small black leather loveseat against the opposite wall.

They sat simultaneously. Brennan looked out the corner of her eye at Booth. He was fidgeting, his hands smoothing over the creases in his shirt, moving up to adjust his tie- once, twice. On his third attempt, Brennan turned and met his gaze directly. She reached over and ran her hands up his ostentatious tie to the tight knot at his neck. She straightened it, hoping that in doing so, he would stop squirming. He shot her a quick smile, resting his hands in his lap. She had seen him nervous before when Cullen had requested to see him. He was his boss after all, and generally, people tended to tense up when meeting with their boss.

The door to Cullen's office opened and a petite red-headed woman walked out, smiling to Booth as she passed. He returned the smile and stood when he saw Cullen standing in the doorway.

"Agent Booth, Dr. Brennan, come on in," his deep voice permeated through the stifled silence of the waiting area.

Brennan stood and followed Cullen into his office, Booth trailing her. They sat down when Cullen had closed the door behind them. Out of the corner of her eye, Brennan caught Booth messing with his tie once again, and shook her head gently.

Cullen took his seat and flipped open a file on his desk. He perused a few pages as Brennan and Booth looked on in silence. Sighing deeply, he closed the folder again, and looked up, meeting Booth's inquisitive gaze.

"I read through your findings on the two couples from Virginia. Have you learned anything more? Cullen folded his hands together on top of the file.

"Yes sir, actually." Booth adjusted in his seat, crossing his legs. "We talked to the first couple's friend, Annabelle Reynolds, today. She told us that the Schwartz's had just gotten back from an anniversary trip. Their anniversary was Valentine's Day."

Brennan interjected quickly, "The DuPont's anniversary was also Valentine's Day."

Cullen looked between the two, seemingly taking in the information. He nodded slowly and looked back down at the file. "In going through the information we've collected, we've found some interesting parallels. I assume you know that the two couples lived only blocks from each other," he paused for them to nod. "I had someone pull up the crime stats for the area: murder, burglaries, missing persons, and we've found that the area has minimal criminal activity, save for three couples going missing. Each couple disappeared in February; one last year, the DuPont's, one the year before, the Schwartz's and another the year before." He handed the file he had been looking through to Booth.

Booth flipped the file open to see a picture of a young smiling black couple. "The Young's," Booth said, reading the case report. "Missing since February 12th, 2005. Never found."

He handed the file to Brennan, who took it eagerly flipping through the pages quickly.

"That's one couple each year," Booth said furrowing his brow. "This definitely means this is a serial killer."

Brennan looked up, "Are you sure? I mean, usually, don't serial killers murder the same type of people? So far, two couples have been Caucasian. This couple is African American."

Cullen nodded, "The evidence we have is substantial enough to warrant an investigation into a serial murder. You're right, though, they usually do tend to focus on only one group of people. However, the similarities between these couples extend beyond that of race." He leaned back in his chair. "Which brings me to the reason I called you in. The FBI has decided to send an undercover team posing as a married couple into the neighborhood. We hope to find the killer quickly before they strike again."

Booth sat up straight. "Sir, with all due respect, this is our case. You can't just pull us off and put another team on in the middle of this."

Brennan nodded quickly. "I concur with Booth. He and I know this case. Removing us and placing two other agents who haven't been involved with this investigation from the beginning would be counter-productive."

Cullen grinned at the squint. She was beginning to think like an agent; probably been around Booth too long. He'd never admit it, but he kind of liked her. She'd grown on him.

"I agree with you both. That's why we are sending in one of our best teams," he paused to see if they understood where he was going with this. He saw realization dawning on Booth's face, but the good doctor still seemed to be in the dark. "You."

Booth grinned and leaned back in his chair, his hand coming up to cover the wide grin that was enveloping his face.

"Us," Brennan asked, confused.

Cullen nodded. "Yes. You were right. It wouldn't be rational to take either of you off the investigation. Seeing as you know the case so well, and you are a good team, we decided that you two should be the ones to go undercover."

He stood before either of them could say anything else, and pushed a small white envelope across his desk towards them. Brennan leaned forward and took it, opening it slowly, her eyes growing wide at its contents. Tilting the envelope upside down, Booth watched as two small white gold bands fell onto her open palm, as well as a silver key. His smile grew larger as he saw Brennan swallow hard. Booth reached over and took the man's ring, sliding it onto his left ring finger, not wanting to admit how nice it felt.

"Your house is being set up as we speak. 412 East Alexandria Avenue. It's in the more historic section. The movers are moving all of the rented furniture in. All that's left is for you two to bring over some clothes." Cullen moved to the door, opening it wide, signaling that their meeting was over.

Booth stood, and waited for Brennan to walk before him. She had placed her ring and the key back in the envelope.

"Remember you two," Cullen remarked as they walked through the doorway. "You are a happily married couple."

Booth grinned at him, leading Brennan away from him.

Cullen chuckled loudly, not wanting to let them get away without a little goading. "Oh, and let me be the first to congratulate you two! I always knew you were a match." Shaking his head he watched as they walked out of sight, Booth shooting an agitated look over his shoulder at him. Cullen closed his door. As the door sealed behind him, he couldn't hold it in any longer, and his hearty laugh could be heard outside in the waiting room, and seemingly all the way to the elevators.

Well? I'd love to know what you thought. Remember, the button is your friend! Push it. :)
