A/N: Okay, so I have a new story! All of the credit for this idea goes to the wonderful redlightning, who I have had the privilege to communicate with during this small process. For those of you who are reading my other story, Halstead's Secret, no worries I am not delaying progress on it I just want to put something fresh out there, especially after that fall finale last night :(. Anyway, read and review on what you guys think about the beginning of this story (Redlightning and I have a lot in mind for it) and also feel free to let me know what you guys thought of the fall finale last night! Enjoy :)

Three Years Ago

"Who is my beautiful little girl", Erin beamed towards her small one year old daughter. The little girl laughed in response to Erin talking to her as they sat on the carpet, the TV playing in the background.

"You know Mia, Mommy is about to start her new job with Grandpa Hank and you will get to meet all the other nice detectives", she said gently brushing away the strands of hair from her face.

Mia just continued to smile at her mother, her big bright hazel eyes listening to her every word. Mia Lindsay was the spitting image of her mother. She had her eyes, her small dimples that appeared when she laughed, and was beginning to have the same dirty blonde locks of hair as Erin.

"This is going to be good for us", Erin whispered, mainly to herself, knowing that working for Intelligence was going to give her a fresh start.

Mia now clapped in response to Erin's comment, laughing at the noise her hands made when they collided. "Ma", she exclaimed laughing.

Erin laughed at her little girl as she gently leaned down to press a kiss on her cheek, "I love you little M", she said getting her to laugh once again.

Present Day

The sound of Erin's alarm clock startled her as she woke up with a jolt. Looking over at the clock she knew it was time for work. Erin sighed as she stood from her bed, glancing over at a picture of her and Mia in the park, a few weeks before she was taken.

Mia was taken a couple of months after her third birthday. Erin thought joining Intelligence would be a good thing, more protection for her and her daughter. When a case went bad though and you make one of the crooks mad, they can alter your life forever. At least, that was the scenario Erin has been living off of for the almost a year. A year and two weeks. Mia would be four years old now.

Shaking her head to focus on the day ahead, Erin stood up and began to get ready for work. Three years ago Intelligence was a job she had gotten to be apart of the team that saved her. Today Intelligence was the job that would save her daughter. Quickly pulling on a pair of jeans and a comfortable t-shirt, Erin was just about to put her boots on when there was a knock on the door.

"Coming", she called out to whoever stood behind her door. Walking towards it, she began to know who it was. He always showed up unexpected.

"Good Morning Sunshine", Jay Halstead greeted his partner while flashing his signature smirk as he handed over one of the cups of coffee he held in his hands.

Erin couldn't help but laugh at the nickname he had easily come up after the one time he showed up to her apartment early in the morning. Jay had quickly picked up on the fact Erin was never fully ready for the day until she had a cup of coffee in her hands. With coffee she was calm and without it she was cranky.

"Thank you", she said taking the to-go cup gently from his hands and sipping it to immediately notice he had perfected her order.

Jay entered her spacious apartment as Erin turned her back to him to pull on her boots. He had been to her place so many time in their years of partnership and even with Mia not here the place was still a little messy.

"I am almost ready", she said escaping off into her room to fix her hair and the little makeup she wore.

"It's all good. I'm early anyway", Jay answered.

"Like always", she replied causing him to laugh.

Jay still was amazed how happy Erin was usually, compared to the months after Mia was missing when she went through a really hard time. Jay had met Mia several times before the incident. She was the sweetest little girl and out of all of her 'uncles', when Mia was at the precinct it was Jay who she wanted to hang out with. Next to Erin and Voight, Jay worked on Mia's case as hard as he could, but when it was called cold, there was no hope left. He knew Erin still had hope though, that one day they would bust through a warehouse and find her.

"You know I don't even know why you waste time in coming here, Halstead", Erin said emerging from her room ready to go.

"Why wouldn't you want to see my smiling face sooner", he teased causing her to roll her eyes.

"You wish, Halstead", she replied. "I think it's just 'cause you want to drive", she teased him.

"Crap Lindsay, you've discovered my plan. Bring coffee to my partner when I can in hopes she will let me drive", Jay answered acting as if he was crushed.

"Not gonna happen, but maybe one day", she casually said grabbing the keys and walking towards the door.

"Yep, maybe one day", Jay muttered to himself following her out the door.

Upon entering the district, Jay and Erin immediately noticed how quiet it was upstairs in the Intelligence Unit. Everyone was at their desks, keeping busy by working on some paperwork.

"What's going on", Jay asked as he went to go sit at his desk.

"Ask Voight. He has yet to give us a briefing", Ruzek answered looking up from his paperwork to Voight's office where he was currently looking down at a file.

"We have a new case", Erin asked as she took off her coat putting it behind her chair.

Before anyone could say anything in return, Voight emerged from his office. "Lindsay", he called out.

Erin looked toward him and he simply nodded indicating it was important. Glancing over at her colleagues, Erin watched as they just shrugged their shoulders not knowing what was going on either.

"What's up, Hank", she asked as soon as Hank Voight shut the door to his office.

"We have a new case", Hank stated shoving his hands in his pockets.

"I figured. Why haven't you done the briefing yet", Erin questioned.

"I needed to make sure you could handle it because if you can't I will hand it to another unit", he explained.

"You're not one to hand off a case, Hank. Even I know that", Erin responded letting a smile grow on her face.

"Just look at it", Voight said handing her the file.

Erin gave him a questioning look as he handed her the file, but he insisted on having her take it. Upon opening it Erin saw why he wanted to hand this over to another unit.

"A four year old boy. Kidnapped from his home last night. The details of the abduction..they are..um", Hank stuttered trying to find the right words.

"They are similar to Mia's", Erin finished his sentence looking towards him.

Silence took up the room for a few seconds, but was washed away when Voight finally knew what to say.

"If you can't handle it, I will hand it off", he said in almost a whisper.

Erin sighed as she looked down at the file one last time before making her decision. "Let me do this, Hank", she stated simply.

"We will save this kid and then it could lead to ideas as to where Mia is. And if it doesn't at least we saved the kid", she continued.

"Please Hank", she implored.

"Let us do this"
