Just an FYI: the "stalker" isn't a character that was on the show.

"David Kennedy?" Olivia asked as the man who lived in the Manhattan apartment opened his door.

"Yeah?" The younger guy was shorts clad with a stained white t-shirt on and he looked like he had just rolled out of bed.

"I'm Detective Benson and this is my partner Detective Tutuola. We have a couple of questions we'd like to ask you."

"Sure," David said as he opened the door more and let them in. "Please, have a seat."

"We know you have some past vendetta against Detective Rollins," Fin said as Olivia checked out the apartment.

"That was a long time ago," David said as he plopped down on his couch and grabbed a beer off his coffee table. He took a swig, "Once she found out that I was innocent I never talked to her again."

"Where were you late last night, early this morning?" Olivia questioned.

"I came home from work about eleven and I went to be. I didn't wake up until you guys knocked on the door."

"Can anyone vouch for that?"

"My neighbor," David said slightly offended, "she knows everything that goes on in this building. What is this about?"

"Don't worry about it," Fin said as he turned and followed Olivia out of the apartment. They checked David's alibi even though they were both pretty sure he had nothing to do with it. When his alibi checked out they got back in the car and headed to the next person's house.

Fin had just turned the car off in front of Jason Mayor's house when his cell phone started buzzing. "Tutuola."

"Fin? It's Amanda." Amanda sounded scared and her voice was a whisper. "I'm in jail!"

Olivia was looking at Fin questioningly so he turned his phone on speaker. "What are you doing in jail?"

"I went outside last night to get some fresh air," she began explaining, "IAB came by and handcuffed me. They didn't even tell me why I was under arrest."

Fin sighed, "Don't worry. Olivia and I are on our way."

"They didn't properly mirandize her," Olivia explained as Fin brought the car to life, "no way are they keeping her in jail."

On the way to the 1PP, Olivia called Cragen and filled him in on the details. He wondered why IAB had arrested Amanda and why they didn't tell her why. He also wondered if this had anything to do with the photos that Nick and Fin had received.

"Keep me updated," Cragen said before hanging up. Somehow Cragen knew that this wasn't a normal case. He had this gut feeling that things were about to get much worse. It was a feeling he couldn't quite explain. He turned to look at the bottle of scotch sitting on the shelf across the room. It was sitting there collecting dust but he could feel it mocking him. He shook his head and turned back to the papers on his desk, hoping to rid himself of the haunting need.

When Fin and Olivia pulled up to One Police Plaza they were surprised to find Nick there. He was suppose to be taking a break at home, not working the case himself.

"What are you doing?" Olivia asked as her and Fin walked up to him.

He shrugged, "I came to bail Rollins out."

Fin crossed his arms in front of his chest, "How did you know she was here?"

Nick shrugged, "Look, I don't need you harassing me. The point is her bail has been posted and she's free to go." Before saying anything else Nick pushed passed Olivia and walked to his car.

"What the hell was that all about?" Olivia wondered out loud.

Fin just shook his head. They went inside and found that Amanda was just getting out to meet them. "Thanks for posting my bail," Amanda said. It was clear that she had been crying because her face was red and she had dried tear streaks.

"We didn't," Fin informed her, "Amaro did."

"Nick posted my bail?"

"Yeah," Olivia said, "then when we asked him how he knew you were here he told us to stop harassing him."

Amanda looked confused. "I don't understand, I didn't tell him I was here."

"Somebody did."

With everything that was going on, everybody was on edge. Amanda had barely said a word the rest of the day and instead spent her time sifting through files, trying to figure out who could be doing this. It was no use trying to get Tucker to talk to them and explain why they had arrested her and why her bail was so little. Amanda was starting to believe they didn't have a real reason but, what could she do about it?

Olivia was sitting at her desk with her chin rested in her hands thinking about everything. She thought about how Cragen was drinking again when it had been so long since he had been sober. She thought about why he could possibly be turning to the bottle again when nobody was under any actual threat. It had to be something else. Something he wasn't sharing. Olivia needed to find out what though because if she had learned one thing in her life it was to never trust anyone.

"Liv?" Fin asked as he appeared from the other room, "can I talk to you for a minute?"

Olivia shot Amanda a look but she was too preoccupied with her searching. She got out of her chair and followed Fin upstairs and out onto the roof. "What's up?"

"I don't trust anyone in this building but you," he said sincerely, "something's going on."

"Yeah," Olivia sighed. "How could someone just get into the precinct without going unseen?"

"You think it was an inside job?"

Olivia shrugged. "If it's one thing I have learned working here it's that you can't trust anyone. I don't want to believe it could be Nick or Amanda but, I don't know them. What I do know is that Cragen is hiding something. It may not be related to this case and I don't know why he would keep it a secret but, he definitely knows something."

"What do we do?" Fin asked.

Olivia shook her head and let out a long sigh before answering. "We're detectives. We investigate."
