Sara looked at Brass incredulously. "So he basically confessed to being there."

Brass smirked. "He said he stopped by, but no one was home."

Nick snorted. "Yeah, and I'm gonna let Greg talk me in to dying my hair blond again."

Sara and Brass glanced over at him with raised eyebrows.

"He's a guilty as they come." Nick continued, not noticing the expressions on the faces of the other two. "I told Sara that I thought Colin was creepy." At that statement Nick puffed his chest out just a little, but enough that Sara caught it.

"Well his little visit to Jenna's is enough to get us a warrant." Brass continued.

Sara tried to restrain an amused smile.

Nick glanced over at her and raised an eyebrow of his own. "What's so funny?"

Sara pursed her lips together and shook her head. "Uh, nothing."

Nick raised both brows and nudged her with his elbow as they continued to follow Brass out to the parking lot. "Spill."

"Green hair wasn't really a good look on you." She smirked at him. "I think your natural color is better." She pointed to his freshly buzzed hair. "But I like it better longer."

He grinned at her and leaned over to whisper in her ear. "So you care about what I look like then." He chuckled softly.

"Don't let it go to your head." Sara quipped and picked up her pace towards Nick's Denali.

Nick was still grinning as he climbed behind the wheel of the SUV and glanced over at Sara.

She smirked. "Concentrate on the case. We have to find solid evidence if we're going to have any proof that Colin McKenzie is the killer."

He winked. "I can multitask." He started the ignition as his thoughts drifted to what Sara had said to him earlier. He could be patient. He would be as patient as he needed to be if it meant he could have a chance at being with Sara. The fact that she had acknowledged that there was something between them that went beyond just friendship had put him on cloud nine even if she wasn't ready to go there yet.

It was a relatively short drive to Colin McKenzie's apartment. Brass kept him occupied outside while Nick and Sara searched his apartment. At first glance, he was a meticulous housekeeper, which didn't really come as any surprise considering how little physical evidence they had found at the scene of the crime. As Nick and Sara searched through each room, they seemed to find nothing, until they located a box underneath Colin's bed.

"Ok, this is creepy. Take a look." Sara opened the box and set it on the floor between them.

Nick furrowed his brow as he sifted through photo after photo of Jenna. "This is one sick dude." He held up a stack of notes that he'd unearthed from under the photos. "I think we've got our guy."

Sara let out a frustrated sigh. "All this proves is that he was obsessed with Jenna Matthews. It doesn't prove that he's the one that killed Camille."

Nick nodded, and raised his eyebrows. "True, but this certainly gives motive. His visit to her house could be the opportunity."

"Although he claims that he visited her house before she would have left for Jamaica." Sara added.

Nick shook his head. "I think maybe he did both."

"Do you ever wonder what possesses someone to stalk someone like this?" As soon as the words were out of her mouth she realized who it was she was asking and she winced as she noticed his jaw tighten. "Nick, I'm sorry." She looked at him apologetically.

He glanced up and smiled at her. "It's ok. It's something I have to deal with, and in this job more than I would otherwise."

"I wasn't even thinking." She knew that he had been more affected than any of them really knew and he didn't really talk about it much.

"Sara, really, it's ok." He spoke softly. "Let's just find something to nail this guy's ass, ok."

She nodded and smiled. "Ok."

After thoroughly searching Colin McKenzie's apartment all they found was the box of photos and notes, but it was enough that Brass decided to pull him into the station for more questioning, and he got a warrant to impound his car so they could search that as well.

His car was nearly as meticulously clean as his apartment was, although they did find several business cards in one of his cup holders.

After shift was over, they made their way out to the parking lot, Nick casting a glance over at Sara. "You want to run by the hospital and see Catherine?"

She nodded. "Yeah, but I want to go by my apartment first so I can get a book for her so she has something to read."

"Something tells me that she'd probably appreciate a romance novel more than the latest copy of the Journal of Forensic Science." He was only half joking.

Sara tried to scowl at him. "I read more than forensic journals."

Nick raised both eyebrows at her in mock surprise. "Sara Sidle?"

She let out a soft chuckle. "I've been known to read a racy novel now and then."

Nick's tone was a bit sultry. "Sara."

She rolled her eyes at him and they continued to banter as Nick drove towards her apartment. Once inside, Sara headed to her hall closet to look for the book she had in mind and opened it a little too quickly, causing a cascade of items to tumble out.

"Who knew that neat freak Sara Sidle had a dirty closet." Nick teased in amusement.

Sara glanced up ready to make a retort, but instead a realization hit her and she looked up at Nick a bit wide eyed. "That's it. One of those business cards we found in his car was for a storage place. I could just kiss you right now."

Nick looked at her with interested smile. "I'm ready and willing."
