AUTHOR'S NOTE: I do not own any of these characters unfortunately they belong to CBS.

ALSO this is my first fanfiction EVER so it would really mean a lot if you could review it, and let me know if there are any errors. It's a short chapter to start but if you like it I'll write more. Thank you!

It was early Tuesday morning when Nell got a rude awakening from her cell phone. She reached over to her side table, grabbed her phone, and held it above herself, so the light was bright in her eyes. She opened a message sent from Hetty that read, red alert, ops ASAP. She clicked out of the message to check the time; it was 4:57 am. Half awake, she stepped out of bed and walked down to her kitchen to start a pot of coffee. She knew that she had to be quick to get to work; since it wasn't often you got a red alert message from Hetty. She slipped out of her pyjamas and threw on jeans and a t-shirt. Normally she liked to wear a cute dress, to try and impress Eric, her dorky co-worker, although she wouldn't admit it. When she was done dressing, she washed her hands and face, brushed her teeth, and gathered her things for the day. By the time all of this was done her coffee was ready. She poured the steamy beverage into a to-go cup and was out the door.

When she arrived at work the rest of the team had already been there waiting, all looking sleep deprived.

"Good morning Nell" Eric said flashing a smile

"Morning" She half smiled "So what's going on? Why did we all get called in so early?" Nell questioned the team, wearing a worried expression.

"Hetty hasn't said much yet, I think she's waiting for the whole team to be ready, we should go let her know everyone is here now" Kensi replied, she herself was confused as to why they had all been called in so early.

They walked over to Hetty's desk as a team, all with puzzled faces, and waited for her to explain.

"We have a case" She started to explain.

"That's obvious" Deeks cut in, Hetty shot him a look and he took a step back. Nell exhaled a small laugh causing Eric to smile.

"This isn't any case; someone is going on a killing spree, murdering everyone that works at Hammer Security. So far 7 employees have been confirmed dead and 2 reported missing. It is your responsibility to find out who is responsible. We have brought in extra NCIS analysts to help out in OPS." Hetty fully explained, "Now you all have a job to do so get at it, oh and Ms. Jones I would like you to come with me"

This had Nell worried, what could Hetty want with her? She hadn't done anything wrong had she? All these questions racing through her mind made her tense up. Eric sensing this gave a small squeeze on her shoulder and whispered, "You got this Nell, don't worry" Eric flashed a bright smile allowing Nell to relax slightly.

The rest of the team scattered throughout the building while Nell stayed with Hetty. Hetty wasted no time in explaining to Nell what she had to do.

"Ms. Jones, I will need you to work undercover on this operation. You will take over the alias Maria as the head of computer software at Hammer Security. We all know very well that you have the knowledge to perform this task. You will arrive to the job site promptly at 8 am, which currently gives you 2 hours to devise a plan on solving these murders, there are no suspects as of yet, but I assume the team has already started looking for one." Hetty had a stern look at her face which meant Nell should get right to work.

"Is that all?" Nell was worried to forget something.

"That is all Ms. Jones" Hetty nodded her head as to allow Nell to be dismissed.

Nell made her way up to ops, wishing she could stay here and work the case with her partner Eric. Ever since she started working here a few years back her and Eric had become really great friends. Nell didn't like having to lie to her other friends and family about her job. She especially hated if there was a really tough case that caused her to lie about her awful day to her friends, when all she wanted was someone to comfort her. With Eric she didn't have to lie, because he was there with her. There was times when she would crash on his couch, or him on hers, after a long day's work. Them being together most of the time, they really understood each other. Sometimes she would find herself blushing when he said how nice she looked, or smiling whenever he smiled. It's just a little crush she would tell herself.

When she walked through the doors of OPS Eric was waiting for the full details of Hetty and Nell's conversation.

"So, anything I should know about?" Eric asked still a bit concerned for Nell.

"I've got to go under cover on this case. I'll be working at Hammer Security under the alias Maria, head of computer software" Nell's explanation still had Eric tense. "You okay Eric? Why are you acting so weird?"

"No… what? No. I'm okay I just umm… don't want you to get hurt or anything" Eric's voice was getting quieter until he was no longer speaking.

"Eric" Nell moved closer to him, "Everything is going to be fine, you know I've got the training and I've been undercover before." She tried to comfort Eric although she herself was still worried.

"I know" He exhaled, "It's just that 7 people are dead and 2 are missing, and it's not every day we get called in at 5 in the morning to work a case. I just want you to be safe" Eric confessed, he slouched down timidly. She had to admit him worrying about her was adorable.

"Hey, you'll be with me the entire time" Nell smiled, pointing to the ear pieces on the table behind them. "Now that that's settled we should get back to work. Want to help me work out the details for my cover story?" she asked, already knowing he would say yes.

"Of course I do" He replied as they walked over to their computers.
