The young girl pulled nervously at her dyed red hair as she walked into the 21st district precinct. "Here I go." She approached the desk sergeant. "Hi, I'm Detective Kayla Ray. I'm here for, uh..." She pulled the paper from her pocket. "...Dawson?" She only got a blank stare. "Um, Sergeant... Platt?" She glanced at her name tag.

"She's in one of her moods." Kayla turned around and saw the patrolman that was talking to her. "I'm Officer Roman and this is my partner Officer Burgess. We can take you up to Dawson. Just follow us."

She smiled at him and followed the two partners. When the trio reached the top of the staircase, Voight was leaning on Lindsay's desk, talking to her. "Hey Sergeant, this is..." Burgess turned to her. "I don't think I caught your name."

She smiled at Burgess. "My name is Detective Kayla Ray. I'm here from Pittsboro, North Carolina."

Antonio stood up from his desk and shook her hand. "Antonio Dawson. We spoke to each other on the phone."

"Nice to finally meet you."

"I'm Sergeant Voight. This is Detective Erin Lindsay, Detective Jay Halstead, Detective Al Olinksy, Officer Kevin Atwater, and Officer Adam Ruzek." Kayla gave them all a silent nod. "Now, let's go over the basics. Over the past 2 or 3 weeks, there has been a sharp increase in unsolved arson cases so the Chicago Fire Department is asking us to help solve them. Turns out the Pittsboro Police Department is looking for the same guy." He handed the floor to Kayla.

"Pittsboro is a small rural town with just about 4,000 people. In the past two years, 5 people have died in house fires including a firefighter, 6 farms have been burned to the ground, and there has been over 800 million dollars in damage. And we had the guy but he burned the police station down, somehow." She pulled a file from her messenger bag and pulled a picture out. "His name is Spencer Johnson. He is Pittsboro born and raised and his family is the wealthiest in the entire county. We've tried charging him with all of the murders and arsons multiple times but the judge wouldn't even give us a warrant, so he's probably corrupt." She walked over and put the picture of Spencer on the board.

Halstead shook his head. "How do you know the fires here are linked to the ones there?"

"Because after my station was burned down, Spencer disappeared until we got wind of your arson cases. Also, he leaves his mark. Have you been informed that these fires have been burning significantly higher than most accidental and arson fires?"

Ruzek checked his copy of the files. "Yeah, most fires are about 1,000 degrees."

"And these fires burned at temperatures over 5,000. That turns a firefighter's turn out gear to dust in a second flat." She pulled another picture from her file and handed it to Antonio. His eyebrows raised when he saw the damage done. "That fireman burned to death before they even knew something was wrong." Antonio shook his head and passed the picture to Lindsay. "It's because Spencer is a chemist, using materials from his daddy's experimental chemical plants to create this stuff that burns so hot. Labs can't even begin to analyze what he uses."

Voight knocked on the board and got everyone's attention. "Alright! We have the informant line set up. We have alerts out with his picture, license plate, and his phone. We need to be on top of this. Halstead and Lindsay, map out his attacks here and NC and what kind of buildings or farms they are. Let's find a pattern. Atwater, Olinsky, Ruzek, hit the streets. Get something from our CI's. Antonio and Ray, compile information. Burgess and Roman, patrol. Make sure you have pictures of him. Ask anyone on street if they have seen him. Let's go!"

Antonio took Kayla into the break room so they could spread out all of her files and his. He handed her a cup of coffee which she graciously accepted. "This is not a lot to go on."

Antonio nodded in agreement but then had a thought. "I know we'll get him, we have to for my sister's sake." Kayla raised an eyebrow at her new partner. "She's a firefighter in the city. I will do whatever I can to make sure she doesn't walk into one of his fires."

"Yeah, I understand that. After he set the first two, they had to start checking the temperatures with thermal cameras before firefighters were allowed in."

"We might need to start taking that precaution. Let's head down to the fire station and brief the lieutenants."

"Sounds good." She followed Antonio downstairs to the car and watched out the windows as they drove. "The city is gorgeous. I have never been to a big city."

"You mean you've stayed in Pittsboro your entire life?"

"Mostly, yeah. I've only been to Raleigh and even then it was for the airport. I didn't get a chance to go downtown."

"Wow. You are the definition of a small town girl."

"Oh yeah. Everyone in Pittsboro knows who I am and everything about me, including when my then boyfriend was about to propose to me, even when I didn't." He looked over at her in surprise.

"Really?"

She laughed when she looked over at him and saw his glances. "Yeah, really. I am the definition of a Southern Belle. Except the housewife part. I mean, my house is the stereotypical white house with a green tin roof. I have 2 big dogs. I was the prom queen and I married my high school sweetheart, the captain of the football team. It's like it's straight from a fairy tale."

"You aren't kidding." He parked the car in the station driveway and they hopped out. He took her to the day room where most of the firefighters were.

Boden walked in the room and glanced at the detectives. "Please give your undivided attention to Detective Dawson."

Antonio nodded a thanks to Boden. "As you know there has been a rash of arson fires. I know from your logs that you have fought two of them. You might remember them. You weren't allowed in the building."

"Yeah, could you explain why?" Gabby looked at her brother.

Kayla stepped forward. "That I can tell you. I'm Detective Kayla Ray from the Pittsboro Police Department in North Carolina. This arsonist is one of my citizens. He has access to very expensive and extremely dangerous substances. Those fires you had to stay clear of were burning at over 5,000 degrees."

They all looked at each other. "Why is he here? Why did he come to Chicago?" Severide looked at Kayla with slight panic on his face as he asked the question everyone was thinking.

"I don't know why he came here. My guess is he wanted to get away from me. I nearly had him. Now, I will give you guys his picture so if you go to a fire and see him in the area, you call me at once. Do not engage him and don't go anywhere near the building. Make sure to check heat levels with the TIC or a heat gun before you go in. I know that's a lot to ask of you but I'm trying to make sure he doesn't kill another firefighter."

Casey nodded his head. "Of course. But how did they find out he was here?"

Antonio frowned. "You heard of the three firemen that died two weeks ago, right?"

Casey's face fell. "They didn't even know what they were going into."

Kayla held up the mugshots before walking to the table and dropping the stack. Antonio pulled Gabby out into the hallway and Kayla leaned against the wall next to them. "Sis, please. Don't go running in without checking the thermal camera." Antonio's phone vibrated. "We have to get back to the precinct. Please stay safe." She nodded and they hugged before the two cops walked back out to Antonio's car.
