Disclaimer: character aren't mine as always, I just like to play.

Summary: An undercover op goes wrong due to another agent, will they save Tony in time and get the guy responsible.

This has been floating around in my head for like two weeks and it's not giving up so here it is. Hope ya'll like the start. I will get the next chapters out of my others soon.

The Subtle Betrayal

Chapter 1- Silence

Silence…

…well, not complete, but close enough. No bickering, no telling them to get back to work because they were getting distracted. No distraction at all. Just working, the typing of reports, the ringing of a certain phone not being answered and the longing looks the phone was given. Would it ever be answered again?

That, was the question. The question that couldn't be answered, not now, not when they didn't have any evidence otherwise. Not when Gibbs' own gut was telling him that the thing he dreaded hadn't happened yet. But the twinge told him it was possible, it was close. But he ignored it; he supposed that it was some form of denial, denial of what he wouldn't believe. The belief that one of their own had betrayed them, they were trained federal agents, they weren't meant to become corrupt, to betray one of their own. Why hadn't he seen it?

Because Tony had trusted him, so by default he had to, thinking that anyone Tony trusted couldn't have possibly been crooked. They had even worked together before, in Baltimore, but a lot of things can change in six years. When they met the first time he didn't think that this guy could ever become corrupt, he seemed like the perfect cop, that's what he remembered anyway. That's why when he had become an NCIS agent a couple of months ago everyone saw the perfect cop, a man that could be relied upon.

But now…now he had caused the silence within the bull pen. Now, he was in the wind and their agent, their friend was missing. Gone without a trace, no leads, nothing. Just the suffocating silence.

And he felt responsible, guilty even. For not watching his agent's six, for not seeing that the guy was going to blow the undercover op on purpose. But that was the risk they all took with every undercover op, a chance that some one would find out, a chance that they'd be killed, every time they even went to work there was a chance.

Tony was surely out of chances by now…no Gibbs would not lose one of his team, not on his watch. The worry and fear he had felt just a second ago turned to anger and frustration. He shouldn't just be sitting here, waiting for a call, a call that would tell them his agent had been found. The BOLO was already out; it was just a matter of time before the people that had him made a mistake. Wasn't it? But they were professional, they'd killed before, that was why they went undercover in the first place.

Gibbs ignored the questioning looks from McGee and Ziva as he stormed out of the bull pen; he needed coffee, needed to find his damn agent.

Autopsy…

Ducky saw the murderous look in his friend's eye and sighed, he knew that it was to do with the fact of Anthony being missing?...

"Got anything else from the body, Duck?"

"Jethro, there was nothing that I hadn't already found."

"Damn it Duck, there has to be something." Gibbs' anger was waning, he couldn't be angry at his oldest friend, it wasn't his fault. If anything, it was his own and he knew it. Seeing the guilt in Jethro's face Ducky spoke up in a somewhat calming tone.

"It isn't your fault Jethro," Gibbs was about to reply but Ducky stopped him; "you weren't to know that Mark would deceive us."

"But I should have Duck." With that Gibbs turned and left, he needed to get all agents looking for evidence, anything that could lead them to where Tony was.

I Know, a short start but it was just to get the idea out there. Stay tuned for more.
