Chapter 1

"Good Morning, McGee. Tony." Ziva David greeted as she settled herself into her desk at NCIS headquarters.

"Shhh…I've almost…Got it! I got it. Haha, Mcprobie, I got it."

"What exactly did you get?" Ziva questioned her partner, curiously eyeing his enthusiasm.

"I just won all nine seasons of The X-Files on eBay, and I only had to shell out sixty bucks."

"What are these, ex-files?" Ziva asked rounding her desk to stand near Tony's. She looks over his shoulder to get a better look at his screen.

"Only the greatest supernatural crime drama ever created." Tony replied, "I want to believe!" He said imitating the popular tagline.

"Yeah, I always hoped Mulder and Scully would just admit they were totally in love." Mcgee added from behind his desk.

"That would be the kiss of death Mcgushy."

"Ah, kiss of death I get." Ziva said, looking down to meet Tony's piercing eyes. They held each other's stare just long enough.

"If you two kiss, it will mean death." Gibbs said breaking the tension. "Grab your gear we've got a dead petty officer."

Gibbs rounded to his desk, coffee cup in hand. He opened the draw that housed his service weapon and badge. Withdrawing both, he placed his SIG holster on his right hip and his badge on his left. "Let's move!"

The team made their way to the elevator and rode it down to the garage in silence.

The scene of the crime didn't look at all like a crime scene. A woman, mid-twenties, lay curled up under a quilt on her living room couch, her television still playing at low volume. Her body looked at peace, as if she were sleeping under a warm blanket. Her quilt was not warm enough though, because her body was cold to the touch. She was definitely dead, but how still remained a mystery.

"Got a time of death, Duck?" Gibbs asked his medical examiner.

"Well I would wager she's been deceased now for several hours. Approximately twelve, maybe fourteen considering the fact that she's been under this blanket all that time.

"Got a cause of death Ducky?"

"Now Jethro, as for as I'm concerned, there is no reason why this young petty officer should be dead. There are no physical evidence of abuse, no evidence of poison, nothing. I won't know anything until I open her up."

"Okay, Ducky." Gibbs turned to his team, "DiNozzo, sketch and shoot. Ziva, bag and tag. McGee, computer." His team scattered to perform the necessary investigations.

"There isn't much here." Ziva complained to Tony while folding the quilt to place in an evidence bag.

"Yeah, strange. There's no sign of entry, no sign of foul play, nothing. I don't even know what I should be sketching."

"Perhaps, McGee will have better luck with her computer." Ziva offered.

"Hardly," McGee added as he walked through the living room, the petty officers laptop in hand, "the computer has been erased. I mean really erased. There is nothing here, no operating system, nothing. Maybe Abby will have better luck with this in her lab.

After a few more minutes investigating the scene, Gibbs rounded up his team and instructed them back to the squad room.

"Wha'da'ya got, Ducky?" Gibbs asked, stepping into autopsy.

"Well my dead friend, it looks as if we've still got a mystery. I've not been able to find anything physically wrong with our petty officer. Abby is currently running tox screens as we speak, but even the most illusive toxin would provide me with some sort of physical evidence of which to piece the puzzle together with."

Gibbs was out of the sliding glass door before Ducky could launch himself into one of his lectures. His next destination: Abby's lab.

"That can't be you Gibbs, I haven't gotten anything yet." Abby called over her loud music.

"Turn it down, Abs."

She obliged, pointing her remote toward her stereo. The noise quieting from deafening to slightly less deafening.

"Gibbs, I don't have anything yet. Why are you here?"

"How long until you do?"

"You can't rush science, Gibbs. How many times have I told you that?" Just as the words escaped her lips alarms sounded signaling the results of her testing.

"How do you always do that? It's like you know I'm going to get something. You never cease to amaze…oh crap. No way." Abby looked down disappointed and in shock of her findings.

"What is it Abs?"

"Nothing, it's nothing."

"What do you mean?"

"It's absolutely nothing. That's what my test results read. There were no known toxins the petty officers body."

"We've got something, Boss." McGee says over Abby's music as he walks into her lab.

"What, McGee?"

"Another dead petty officer, found in the same conditions as the one down stairs. And get this, they work together in the same office."

"Do we know anything else McGee?"

"No." McGee answered as Ziva and Tony joined the team.

"Looks like this could be a case for Mulder and Scully, huh Boss?" Tony added.
