Glenn walked purposefully through the front doors of the Vegas PD building and headed towards the elevators. His badge hung on the outside of his shirt, for once, and it gained him immediate access to the administrative areas of the building. He angled his way into the labyrinth of lab rooms, nodding his head to various detectives as they acknowledged him. It was the start of the night shift, he knew, so Grissom should be giving out assignments now. Passing Viviane's lab, he glanced inside, not expecting her to be there, but when his suspicions were realized, his lips tightened and his eyes flashed in anger. He quickened his pace until he came to the break room, where the team was assembled.

Glenn slipped into the room just as Grissom was finishing. Warrick and Sara left immediately, but Nick lagged behind with an interested expression. Like Greg, he was always pleased to see Glenn, who always had interesting news on the federal level. Today Glenn's eyes were stony, however, and he stood tensely as Grissom turned to address him.

"Good evening."

Glenn nodded in response. "Can I have a word with you, Grissom?"

Nick stared at Glenn silently. "Does this have anything to do with Greg and Viv calling in sick?" he asked suddenly.

Glenn looked at him sharply, then back at Grissom. "They called in sick?"

Frowning slightly, Grissom replied, "Not exactly. They both e-mailed me asking for some time off. The lab wasn't busy and they had time saved up, so I didn't give it a second thought."

Glenn crossed his arms and stared at the floor, suddenly looking lost. After a minute he looked back up at Grissom with a serious expression. "Can I have that talk now, Grissom?" he asked solemnly.

Nick stepped forward. "Look, you can't just keep us out of the loop like this. They're our team, if they're in trouble we want to know," he said angrily.

"I can't —"

"You can't keep this a secret."

Grissom pursed his lips thoughtfully. "I can't guarantee my team won't hear about this after you tell me, Glenn."

Glenn nodded, unsurprised. "This stays in the room."

They nodded gravely, and Glenn continued. "I called Viviane and Greg; they're not answering the phone."

"You've been to check on them." Grissom asked, but it wasn't really a question.

Glenn nodded. "They're gone."

"And you're sure they didn't leave on their own? Why would someone kidnap them both?" asked Nick. "Who would want them?"

"I have my suspicions," said Glenn grimly, his jaw set.

"Care to fill us in?" asked Nick stiffly. He was clearly upset that his friends were in danger, and from something it looked like they knew nothing about.

Glenn sighed and motioned for them to sit. When they sat down, Glenn shook his head ruefully. "It's my fault. I shouldn't have told them my plans. I told them what I was doing...that I was chasing something.

"There's been a mole in the Justice Department for some time. I had my suspicions on who it was for some time, and their link to ATF allowed me to help with the FBI's investigation. We had to see how far the leak went, so we kept it quiet in case he got tipped off.

"This past Christmas I told Viv and Greg about the investigation so she could be more careful, just in case," finished Glenn. He rubbed his eyes tiredly and sank into an empty chair.

"What makes you think he's the one that has them?" asked Nick.

"Because of who the mole is," sighed Glenn. He leaned forward, elbows resting on his knees. "Paco...Francisco Vierres...was on Viv's team a while ago. He was very close to us... He knows who I'd talk to, and he knows who to go to for information about me. He and I had a bad falling out and I made the mistake of not sending him straight to jail. He wasn't fired then, but he should have been.

"I've been keeping my whereabouts a secret for a while now. They're the only ones I told. My cover at ATF has been holding for now, but it looks like Paco's gotten wind of the investigation, and now he's trying to get at the info they might have."

Nick frowned. He was sure they were getting a simplified version of the story, and it seemed like Glenn was still keeping something to herself.

"I need your help. Please." Glenn raised his head, hands open in supplication. "Paco's very dangerous. He won't hesitate to kill them if they don't tell him what he wants." He looked at them bleakly. "It may already be too late."

Grissom sighed and stood up. He looked over at Nick. "We can keep this under wraps for now. Tell people only what they need to know. I don't want anyone alerting the media."

Nick nodded.

"And get Archie running a trace on that e-mail. Let's recreate their last hours."

When Nick had left the room, Grissom turned back to Glenn, who was now standing by the fridge, arms crossed and deep in thought.

"I'm surprised you're not taking a more active role," said Grissom, eyebrow raised.

Glenn turned to look at him. "It's best if I'm not too conspicuous. I don't want him to know I know they're missing," he said, voice measured.

Grissom pursed his lips thoughtfully. "I think there's more to this than you're telling us, Glenn. But I trust you have a good reason to do so, so I won't ask you to tell me everything."

Glenn inclined his head. "Thank you," he said quietly.

"We'll do our best," continued Grissom. "They're our friends too."

They met in Archie's lab soon after. He'd been asked only to run the trace, but he was no fool. There was a tense set to their shoulders that told him everything he needed to know about the situation. He sat back, quietly waiting for Grissom. When he and Glenn stepped into the room, both wearing serious expressions that confirmed his suspicions, Archie began speaking.

"I traced the e-mail to an abandoned town in eastern Nevada," he said, showing them the tracer program. "Whoever sent the email made no attempts to hide it. It's almost as if they wanted someone to find it."

Grissom pursed his lips thoughtfully and turned to Glenn, but the room was empty. Glenn was gone.
