"So this is the Las Vegas crime lab huh?" Ben asked stepping out of our car. "Where our favorite girl worked for so many years…"

I looked over the hood of the car at Ben and threw him a sarcastic smile.

"Are we just going to stand out here or are we going to go in?" Mike asked as he came to stand next to me.

"Well, aren't we just a little anxious this evening." I said smiling up at Mike.

"Not at all…I just want to get started." Mike kissed my lips.

"Mike that's called being anxious." Ben said mockingly.

"Shut up and get inside." Mike threw in retort.

Ben put his hands up in surrender and said "Okay Okay, whatever you sat."

I smiled as began to walk towards the doors. Ben and Mike soon followed, having no choice really to do otherwise really.

I walked inside and smiled at Judy as I continued my way into the lab. I turned around and said "Ben…would you like the grand tour?"

"I would love it." Ben said excitedly, walking up to me and linking our arms together.

I heard Mike say "Oh brother." Before Ben and I set out, Mike following closely behind us.

I showed Ben all the labs, layout rooms, offices…everything. We arrived at the break room, still linked arm through arm, everyone was waiting for us.

"Sorry we're late, Ben wanted a tour." I said laughing. "Everyone this is Ben, one of my co-workers from New York…Ben this is Nick Warrick, Greg, Brass, and…Grissom." I was not unaware of the fact that Catherine was not there.

There was a collective hello before Grissom began to talk.

"Okay so, we've made some headway on this case, but some headway is not enough…we need to buckle down and catch this bastard."

There was a collective nod before Grissom split everyone up.

Ben followed Mike and I to a layout room.

When we arrived we got to work, there was no laughter or joking around, just serious, concentrated silence.

Half way through the night I looked up at Mike and said "Do you know what strikes me as odd?"

"What?" Mike asked as he looked up from a pair pants he had a magnifying glass to.

"This guy…Chase Butler shows up in all of these cases, knew every one of the girls in some way, but there's no forensic evidence linking him to the murders."

"What are you saying Sara?" Mike asked looking not at all puzzled.

"I think we have an experienced killer on our hands…but there is nothing linking this man to any of the murders, except…" I paused pulling up a finger print "This print, which was dismissed as trainer touching the personal items of a trainee."

"Sara…what are you getting at?" Mike said already knowing what I was going to say.

"He also called 9-1-1 for two of the girls."

"Sara…"

"I think we should consider…undercover work."

Mike gave me a knowing look, but what Ben said next surprised me "I think your right Sarah."

"What!" Mike and I both said in unison.

"I think it's this guy too…we just need to prove it, and undercover work seems to be the only way to go about it."

Mike sighed "Maybe your right…we should talk to Grissom about this and see what he says…but…I don't know…I'm worried."

"Why?" I asked knowing full well what his concerns would be.

"Sara…who'd be going under? And don't tell me you don't know…it's most likely going to be you."

"Mike you worry too much…nothing's going to happen to me." I said as I moved to leave the lab.

Mike grabbed my hand before I could "Promise me?"

"I promise." I said with a tender kiss and then I was out the door.

I walked quickly down the lab halls; I was almost to Grissom's office when I saw Brass walking towards me.

"Brass…I need to talk to you…and Grissom…I'm heading over to his office now…can you come?"

"Sure thing cookie…is anything wrong?" Brass asked voice full of concern.

"No…yes…no…just come." I said before I continued to walk.

When I arrived at Grissom's door, Brass was right behind me. It was him who knocked on the door when I didn't.

"Come in." Came Grissom's tired voice.

I opened the door and Brass followed. Grissom looked up and furrowed his brow when he saw who it was.

"Sara…is there something wrong?"

"Well…there's something I need to discuss with the both of you." I said looking from Grissom to Brass.

"Sit down." Grissom said motioning to the two empty chairs in front of his desk.

Brass took one and I took the other, I shifted in my seat before I started.

"My team and I found a common link to all murders. His name is Chase Butler. He was a trainer for all the girls. His print was found at a scene but it was dismissed, he also called in for two of the girls other than that there is nothing linking the man to any of the murders… My team and I think that this is out guy…we want to go undercover…catch the guy in the act."

There was silence and the Brass said "Sara are you suggesting that you go undercover?"

"Well, me or Catherine…"

"Catherine no longer works here." Grissom cut in suddenly.

I was stunned…I didn't know what to say so I didn't say anything.

"I need an answer." I said hurriedly.

"This will have to be thought through…planned." Brass said.

"I know." I said slowly looking Brass in the eye.

"Are you sure you want to do this?" Brass asked.

"I'm positive…if this brings this guy to justice…then yes…I want to do this." I said confidently.

Brass sighed and then got up "Okay…I have to go clear this with the DA…I'll be back."

I nodded and Brass turned and left the office…leaving Grissom and I alone.

"Grissom…" I started softly.

"She left me last night." He said not looking at me.

"I'm…I'm sorry."

"I should have seen it coming…she was having an affair…she said that she couldn't work here anymore…said she couldn't be with me anymore…she said she'd meet with her lawyer to get the divorce papers…she said it was because my heart never really belonged to her…" Grissom trailed off on his rant.

"Girss…I'm so sorry…"

Grissom cut me off again "She said it belonged to you."

His confession took me aback.

"Grissom…"

Grissom cleared his through at looked back down at his papers. "Sara you should get back to work…I'm sure Mike and Ben are waiting for you."

I nodded almost numbly as I got up from my seat. I walked out his office door, resisting the temptation to turn back around and look back, but I didn't. I kept walking, determined to tell Mike and Ben the news.

A/N It may not seem like it but the last couple chapters are coming up like 6-7 more at the most...i think. lol thanks for all the reviews!
