Morgan and Prentiss walked into Jonathan Martin's house with the familiar sense of apprehension and dread that accompanied them on all such excursions.

Talking with the family of a dead man was never pleasant. It went one of either two ways; they found out that the person in question was terribly loved and would be desperately missed, or there was something dark about the dead man that they would need to figure out in order to solve the case. Either way it was never easy, never forgettable.

"Do you wanna talk to the mom?" asked Morgan, nodding towards a tall woman with short blonde hair.

"Yeah, go find the sister, I can handle this." Morgan walked away, and Prentiss made a point to mentally sigh, preparing herself for the tears or the lies, whichever would come first.

"He what?" Hotch said quietly, looking at Reid and Rossi with a sense of apprehension.

"He practically tackled Reid. The kid held up a necklace and the guy went berserk."

"Actually, berserk is a term that was used to describe a particular tribe of Vikings as they raided villages. Before the raids they would drink copious amounts of alcohol mixed with a type of plant that increased testosterone and adrenaline. Then they would work themselves into a frenzy and… uh…" Reid sputtered out, his train of thought lost.

Hotch knew that that wasn't good. Generally, when the good doctor began spouting random facts about the meanings and origins of words he was a little spooked.

But the team leader was torn. Obviously whatever this man had done had scared Reid, but an odd tugging at the back of his mind was telling him that something was really off about his case. And that they were going to need all the help that they could get.

"But, what about the necklace? The one that made Mr. Dresden so anxious in the first place."

"He took it to Karren so she could put it into evidence." Rossi replied.

"Was there anything special about it that either of you can remember?" Hotch asked.

"Why don't you just go get the thing from Murphy?" J.J. asked, despite the mound of paperwork on the desk in front of her, she had apparently heard most of what had been said.

"Well, it looks like she and Dresden are having a conversation and I would hate to interrupt." Hotch nodded toward the window.

Rossi looked toward the window and saw Harry and Karren yelling at each other. Something told David that there really wasn't anything to worry about, that they did this often. But that didn't mean it wasn't annoying.

"You know, I've half a mind to lock him out. So far, all he's done is look crazy and scare Reid."

"Yeah, but we're going to need him for something eventually." Hotch's phone rang, it was Morgan.

"Agent Hotchner."

"Hey, Hotch. There's nothing here. The victim before the latest was pretty normal. Jogged every night, worked out, single. A regular bachelor."

"So the only thing that the victims have in common is the fact that they're healthy and attractive."

"It looks that way."

Hotch sighed. "Thanks Morgan, come back down." He hung up the phone.

"We're not even close to a preliminary profile, are we?" Rossi sighed with him.

"No. But the clock is ticking. The cooling off period between these last two murders was only two days, as opposed to the week it took him to go after Jonathan."

"So we're running out of time?"

"It looks like that."

Reid was glad that they weren't talking about him anymore. He was the youngest, the baby. They all worried about him to some extent, he knew that. And sometimes he appreciated that extra attention. Just not right now.

There was something bugging him about this whole case. He was looking at a map, trying to come up with a geographical profile by organizing a map of the city of Chicago into a grid.

The only problem was that every part of Chicago had supplied a victim, no matter how he sliced it, there was no comfort zone. No pattern, no radius, no perimeter….

No comfort zone.

He pulled out his phone in a hurry and dialed. "Garcia?"

"Yes, the Queen of all things Technological is speaking."

"I need to you too pull up all the place that the victims were found and see if there's anything in common."

"Okey-dokey, anything in particular we're looking for?"

"Maybe, just see what you can find."

"Alright….. Oooh, it looks like all of the places are tourist sights. But you would know that already, wouldn't you Reid?"

"Umm, yeah. I'm just a little off today, I guess."

"Reid, honey are you-"

"Yeah, thanks Garcia." He hung up just as Prentiss and Morgan walked in.

"Guys, I think I got something." Reid called behind him.

"What is it?" Murphy had walked in, Harry following sullenly behind her. Reid didn't bother to meet his eyes.

"Okay, so most serial killers have a comfort zone. You can usually mark where each of the victims was found, murdered, or abducted, and plot out a circle. The killer will live somewhere in the area of that circle.

"But there's no pattern to this. They've all been found at seemingly random location all across the city."

"So," Murphy said with a frown. "He doesn't live in Chicago?"

"No, he didn't live in Chicago. All of these places are tourist attractions."

"Places that people who live in Chicago tend to avoid because of all the traffic and annoying people in khakis" supplied Dresden.

"Exactly, these place are almost completely empty at night, except for the people that work there. The victims all worked where they were found."

"Not the last girl, Melissa." Dresden interrupted.

Rossi shot him a look, but Reid jumped right back in. "Not true, that's a historic neighborhood, recently restored. Melissa was a history major, my guess is she was studying the architecture and style of the old building when she was killed."

"So, this guy's getting his victims from travel brochures?" Murphy asked disgust clear on her face.

"It looks like it." Reid replied slowly.

"Wouldn't that make the stressor something that happened after he came to Chicago, something that made him mad at the city." Prentiss asked.

"No," Hotch said. "He's not taking the bones as trophies, so he's using them for something."

"He came to Chicago to kill." J.J. realized.

"Or to prove a point." Rossi sighed.

Harry had a distinct and gut-wrenching feeling that the point was to be made to him.
