I'm sorry last chapter was really short, but this is longer. Hope you like

Seeing Elliot's face so close to her was tentative... but she finally stepped back

"El... I don't know what to say" Olivia said

"You don't have to say anything. I just need you to understand me, Liv... I'm sorry I told you that, I shouldn't have to" Elliot said

"Don't apologize, it was the best you could have done. I understand you now, and I'll try to make this case easier for you... but we need to catch the guy okay?" Olivia said and Elliot nodded

Elliot and Olivia started walking back to the precinct, when suddenly Olivia stood in front of him and push her lips against his. Slowly and passionate, their first kiss ever lasted more than regular kisses. They finally ended it.

"I don't want you to kiss me just because you're sorry" Elliot said

"I didn't kiss you because of that" Olivia said, flirting

"Then why you did it?" Elliot asked

"Surprise, I'll tell you later. Let's go, we have work to do" Olivia said, she grabbed him by the hand and pushed him downstairs.

"Okay let me see if I understand" Capt. Cragen started " Alicia and Daniel received a threatening letter from a Detective Milgram. We know that 'Detective Milgram' is an alias used by Merritt Rook, who escaped during his arrest last year"

"Yeah. Basically" Elliot said

"Well, John, Fin, grab a picture of Rook, show it to anyone in the squad Alicia works in. Someone has to recognize him. Elliot, you and Olivia go interview that company he used to work in, ask if he returned, if he sent a resignation letter, anything.

"Captain... I think we have a problem here" Olivia said, reading a piece of paper

"What is it?" Both Elliot and Cragen asked

"I just received this" Olivia gave the paper to Elliot. It said

Detectives Benson and Stabler... It's been a long time right? I'm glad to see you still are smart. You interrogated my friend Alicia, you read her letter, found out she was having a relationship with Dan. But you haven't found the killer. Well, I'm writing this to make your jobs way easier, I'm going to confess. Yes I killed Daniel, why? I'm not telling you. Now you must be thinking: hmm he became really stupid, with this letter, when we catch him he's looking for a life sentence. But guess what?I'm not worried... You're not going to find me. And since we've already established the point of your intelligence, I will sign with my real name. Have fun trying to find me...

Yours, Merritt

"Son-of-a-bitch" Elliot said

"He's watching us... how does he knows about our investigation?" Elliot said

"I don't know. Take that letter to the lab, maybe Warner can gives us a lead. But be careful, Rook might be watching you all the time. If he knows we have something that can link him to the murder, he's not gonna cross his arms" Cragen said

"He's not stupid. He must have an spy, because he can't risk to be cached" Elliot said

"I'll call IAB" Cragen said as he entered to his office

"Are you OK?" Elliot asked Olivia

"Sure, I just need to bust this guys balls" Olivia answered

"Liv... I think we need to talk"

"We'll talk later, I promise, but now we need to concentrate ok?" Olivia said. The telephone ranged

"Detective Benson, SVU" Olivia answered

"Hi Olivia... such a beautiful day, right? Nothing better than talking in the roof with your partner," the voice of Merritt Rook said

"Where are you and why are you stocking us?"Olivia asked, serious and scared

"I just want you to know that I want to meet you and Elliot soon"

"What makes you think we would go after you?"

"Because I'm a big fish. Tomorrow, 6:00am at your apartment... yeah, I know where you live. Be sure no one but Elliot and you are there... or you'll see the consequences" Rook said, and then he hung up

"It was him, right? What did he say?" Elliot asked

"He wants to meet us tomorrow," Olivia answered, in shock

"Us?"

"Just you and me... El, I'm sure now: he's watching us, he knows what happened at the roof," Olivia said

"Liv... what do we do now? It's not safe to meet him. And you can't go to your apartment, he could break in, and... I don't know what he would do," Elliot said, worried

"So? Should we tell Cragen and go into Witness Protection? Or what?"

Ok, tell me what you think, please! Come on, it doesn't take you more than two minutes
