A/N: Sorrry for such a long wait for an update! Life has been so busy and demanding, I haven't had much time to write anything at all. But this story is my favorite, and finish it I shall! Thanks to all those who have reviewed so far.

"She said what?" Casey exclaimed while running down the sidewalk, trying to keep up with Olivia's fast pace.

"That's what I was thinking," Olivia confirmed. "I couldn't believe that a lead on this case was falling right into our hands, but she described the attacks in her town, and they were identical to the ones happening here." Olivia, who had been frantically flagging a cab, opened the door to the one that had stopped and climbed in after Casey.

"And they said they were coming in on a flight tonight?" Casey asked.

"Yes. This guy must have done some serious damage in their town, because they're in as much of a hurry as we are." Olivia suddenly frowned. "Should we be worried that they know details of this case that haven't been released to the media yet?"

Casey sat in thought for a minute, pondering the question. "Normally I would say yes, but why would they have contacted us if they are involved? I know there are some exceptionally stupid criminals out there," Casey smiled as Olivia snorted in agreement, "but I don't think I've ever met one stupid enough to call and then fly halfway across the country to the scene of a crime that he or she committed."

The cab arrived at the precinct and the ADA and the detective got out. Olivia insisted on paying for the cab since Casey had done so the night before, and they made their way into the precinct.

"Hey, look who the cat dragged in!"

Olivia groaned. Casey had phoned in and told her assistant that she was going directly to the precinct, but unfortunately, the two had been running a little late, meaning the squad room was full when the two ladies walked in. Together.

Elliot and Fin both gave them a 'what are you two doing arriving together?' type look, but knew enough from Olivia and Casey's respective glares to keep their mouths shut. Munch however reamained oblivious.

"Hey, did you two just--"

"Shut it John!" both women ordered.

Humbled, Munch returned to his desk and pretended to be very interested in his paperwork. Elliot and Fin snickered to themselves, but also sat at their desks. Olivia and Casey shook their heads at their colleagues and walked into Cragen's office.

"Captain, we have to talk to you," Olivia stated.

"We think we have a lead in the case," Casey explained.

"Well, lets hear it!" the captain exclaimed as the other squad members streamed into his office.

"We got a call this morning, from a girl who said she lived in Sunnydale, California. She claims that the same attacks were happening in their town until about six months ago."

"What happened six months ago?" Elliot asked.

"This is where it gets weird," Olivia winces. "Sunnydale collapsed into itself six months ago. Nobody knows why. No scientists can explain why. Somehow the people were evacuated before it disappeared, but when the LAPD interviewed Sunnydale's population, no one in the town could say why it happened. The two women are on their way now to talk to us in more detail about what they say they know."

Cragen nodded, trying to understand what could be going on. Deciding that they needed to hear what the women had to say, he addressed all the detectives.

"What time are they getting in?" Cragen asked, looking at his watch.

"5:12," Olivia confirmed.

"You and Casey should get down there now. Knowing LaGuardia it'll be hell trying to get yourselves in and them out. I'll start arranging for hotel rooms," Cragen ordered.
