Author's Note: This idea ran through me after reading HooahSergeant's stories. They're awesome. And I know this isn't a typical cop story but I don't really care for details into what cops do or anything. So I'm just writing as a simple Glee!Fan and just winging it... Plus, thing's could change in the future, right? So this is completely AU. :)

Chapter One

XXXXXXXX

"God damn it, Santana! Faster!" Quinn found herself gasping for air. Sweat poured down her neck and chest.

There was a bit of a pause before Santana's voice rang through the blonde's ear. "Damn, Q. Didn't know you liked it rough?" She smirked.

"Now's really not the time!"

The two breathed in each other's ear…. Through their earpieces.

"Well, I'm sorry that my fingers get more workout than my legs."

"Not my fault you never get on the treadmill with me!"

Detective Quinn Fabray sprinted down the dark alleyway, attempting to apprehend a criminal wanted for murder and her partner, Santana Fucking Lopez was so not helping. "Stop! I will shoot!"

He knocked over a trash can but Quinn jumped over it and continued to follow him around a corner, but as soon as he turned, he was knocked over by a raging Latina. Quinn stopped and put her hands on her knees. "It's about time!"

"The fuck you mean 'it's about time'? Do you realize how many cars almost hit my hot ass? Stop moving around before I knee you in the nuts, asshole."

"You guys married or something?" The criminal asked, his face in the pavement.

"Shut up!" They both yelled.

Quinn took a much needed breath and reached for her headset. "This is Fabray. We got him. We're ready for pick up."

"This is Sergeant McNally. Good job, girls. We're on our way."

Santana handcuffed the criminal and sat on him to hold him down. "You know, you don't have to scream in my ear all the time." Quinn pulled her headset off and stared at the Latina.

"Well you like to ignore me."

"It's kinda hard when you're like… screaming."

They could hear sirens in the background. "You're ridiculous. I told you to get in the car to cut him off, not run after him like a track star."

"I was a cheerleader – YOU were the track star, remember? My mind? Not there all the time, Fabray."

Quinn sighed and rubbed her temples. Why was she Santana's partner again? And thank god the case was over.

XXXX

"Fabray! Lopez! Good job on your last case, but unfortunately there's no break. We have a new case for you – it's high priority."

"Really? Can we look at it tomorrow? We're kinda tired… Uh, sir," Santana smiled.

"No. You can't." Santana groaned. "Look over it tonight. I don't care where or when but I expect you to be in my office tomorrow at eight AM sharp to explain how you're going to go about it," Chief Jacobs said as he sat down.

"Don't mind her, sir," Quinn started, "She's just a little upset that she's getting slow in her old age."

Santana narrowed her eyes and looked over her shoulder. "Oh, bite me, Fabray."

"You'd like that wouldn't you?"

Chief Jacobs cleared his throat. The two women hadn't stopped fighting since day one. "Why did I partner you two up again?"

"Because we get the job done, sir," Quinn answered, but tensed when Santana wrapped her arm around her shoulders.

"And I wouldn't know what to do without my little Quinnie," Santana smirked.

Quinn carefully wrapped her hand around Santana's wrist and extracted her arm from her shoulder. "Get off of me S."

"You two are probably the oddest people I've met in my life. Now get outta my sight and start on this case. Dismissed."

Quinn let out a sigh and hurried out of his office with the new case file in hand. "We barely finish one and he's shoving another in our faces. Can't we ever catch a break?"

"Let's head home and work on it there," Santana said as she yawned.

"No way. Last time you said that we ended up going straight to sleep and having to wing it the next day. We're going to Doc's."

"But…"

"No, San. Let's get the hell outta here. The sooner we work on this, the sooner we get done and can go home."

Santana groaned. "Why do you always have to be so professional and shit?"

Her partner scoffed, "I'm not the only one who got into this job, Santana."

"Shut up, Fabray. I'll let it slide this time. All that work out gave me an appetite."

Quinn rolled her eyes as she unlocked the car for them. "Just get in the damn car aleady."

XXXX

"Here's your coffee, ladies," the young waitress smiled as she set the two cups down. "Enjoy. Let me know if you need anything."

"Will do," Quinn said, looking over at Santana, who was eyeing the waitress up and down. She rolled her eyes and gave Santana a hard, yet subtle, kick to the shin. Santana clenched her jaw and smiled 'politely' as the waitress walked away.

"Fuck…" Santana reached down below the table and rubbed the spot Quinn hit. "The fuck Fabray?" She whispered harshly.

Not looking up from her file, Quinn smirked and took a sip of her coffee. "You do have a girlfriend, Lopez… Or did you forget already?"

"I was looking, not touching. Big difference. Plus, my girlfriend and I aren't even official. We're more like…"

"Not together? When we're not on a case or sleeping, you're talking about her constantly. What's her name again?"

"Brittany." Santana couldn't even say the girl's name without smiling.

Quinn glanced over the file at her partner, "see, that's what I mean. Now let's look at this case so we can go home."

Santana sighed and grabbed her file. She picked up her cup of coffee and took a sip as she opened it. Once her eyes landed on the photo, she nearly spit out her mouthful of coffee. "I think I've seen her before."

Quinn lifted her eyes to glance at her partner over the folder yet again. "What do you mean you've seen her before?"

"Through Brittany."

"Your girlfriend? How does she know her?"

"She choreographs the Broadway Show the… 'victim' is in."

"Hm…" Quinn ran her finger over the photo. There was something about this case that irked her…

There was a man stalking this woman. The letters were sweet at first, but then they started to get more threatening. To top it off, she received a letter at her own private residence with a picture of her in her bathrobe while inside her bathroom. The man had finally gone too far and she was now fearful.

Quinn must've been too silent for too long, because Santana scoffed and spoke, "Quinn, no matter how many times you read over that, you're not going to understand why he's doing it."

"Are these people really living that shitty of a life to feel like they need to stalk someone else's?"

"I don't know, Q."

Quinn laid the folder down on the table between them and motioned the waitress over to their table to refill their cups. "What are we going to do to help her? Chief said it's up to us."

"And here I thought you were the smart one," Santana joked as she sipped her coffee. She kept her eyes on the wooden table as the young waitress came over to pour them more coffee. The last thing she needed was to explain to Brittany were the massive welt on her calf came from.

"Doesn't mean I have to come up with everything…"

The two thought in silence as they continued to look through their files. Quinn pulled out one of the letters the stalker had sent her. It seemed so innocent.

Dearest Rachel,

I should start this out by admitting to you that I didn't really want to see your show. I was forcibly dragged to it by my girlfriend. I sat in my seat and watched with boredom during the first few minutes. Then it happened. Then I saw you. I saw the reason why my girlfriend was so excited to see your show. You took my breath away. The combination of your voice and your amazing beauty should be illegal.

I'm very thankful now that I came to your show. I may have only seen it once, but that's all it took for me to fall head over heels. I've already purchased tickets for a show you have coming up next month. I'll be bringing my girlfriend, but I will be paying attention to nobody but you. I hope you won't disappoint. Though I doubt you ever could. I'll see you in a month.

Yours,

Raymond

PS: Write me back?

'Sounds like a regular fan letter…' Quinn thought to herself as she pulled out another.

My dearest Rachel,

I've watched you from afar for too long, I can't handle it anymore. Why won't you respond to me? I've been to every one of your shows since I first saw you, every time you continue to ignore me. Why?

I followed you home after your show last week. I just wanted to know why you continued to ignore me. When I got up to your door, I just couldn't bring myself to knock on it. Instead, I just watched you. I watched you as you walked around in your house in this pretty little pink silk robe and a towel wrapped around your hair. These pictures I'll cherish. Especially as I see more and more of you each night. I'm sure one day, I'll finally get to see you naked. Completely naked.

I love you,

Raymond

Quinn felt her throat tighten as she read over the last two words of the letter. "He's showing the signs, San…"

The Latina frowned, instantly knowing what her friend was referring to, "Are you sure? Let me see that," she grabbed the letter and started eyeing over the words carefully. She looked up and saw the look on Quinn's face. "Q… It won't go down like that."

Quinn did nothing but drink her coffee, trying to think of a way to make sure this case didn't go like her last stalker case.

And she had an idea. A very risky idea.

XXXX

She couldn't figure out how someone could be obsessed with someone they never met….

When Santana and Quinn got home, the two went to their separate rooms and slept. Or at least Santana did. Quinn couldn't stop thinking about the case. She was sitting on her bed, the files ripped apart on her bed, trying to tear it apart – sentence by sentence, piece by piece. The dozen letters this 'Raymond' had sent the victim was causing her stomach to get tied into knots. They sounded so much like Lucy Macready's case from three years ago.

She was a new detective. She and Santana were assigned to the teenager's case. Quinn was at the house day and night protecting that girl. She couldn't help but treat the girl as a little sister. But a simple distraction sent the detective away to inspect the backyard because the girl's dog wouldn't stop barking. She figured that dogs barked when something was wrong. At least that's what she told herself as she walked to the back of the house, gun drawn.

That was when he came. He pounced while the young agent was distracted. He successfully snatched Lucy from her bed as she slept, stuffed her into his car and was gone in a matter of five minutes.

Three days passed by the time the duo had found them. Lucy had been raped and murdered.

Quinn couldn't sleep for weeks after that. The trial was long and hard for the detective. The perpetrator was eighteen and sentenced to twenty five to thirty years in prison.

Quinn sighed and ran her hands through her short blond hair to try and clear her thoughts. It still haunted her to this day. Had she not been so easily distracted, Lucy would still be alive and she wouldn't have to live every day with the guilt of her own mistake.

Was her plan really going to work? It was hard telling. She did it once, only she wasn't undercover… If she ran it by the Chief, he probably would deny it based on what happened last time. Even if Jacobs agreed to it, he'd have to run it by the victim and her manager. Quinn's plan would have her at the victim's side, day and night. She'd be living with her, sleeping one room away or even on the couch. She'd be at every performance. She would never leave her sight.

She sighed for what seemed like the fiftieth time that night. She closed her eyes and leaned her head against the pillow against her headboard. Before she knew it, she was in a peaceful sleep.
