Jack was only half listening to Martin's report. He knew that he should be paying attention, that some poor girl's life was at stake, but all he could think about was the newly acquired knowledge that Martin and Sam were together. How long had they been hiding their relationship? How long had they been sleeping together right under Jack's nose, and he'd had no clue? Jack knew that he had no claims on Sam, that she was a single woman and more than welcome to be with anyone that she wanted. But did it really have to be Martin?

"Jack?" Martin asked. "Are you listening?"

Jack jerked out of his musings. Martin and Sam were both staring at him, looking concerned. "Yeah, I was listening."

Martin raised his eyebrows, as if he didn't believe him, but didn't say anything about Jack's lapse in concentration. "The doorman said that five minutes after Kate got home, a guy in a Mets baseball cap entered the building. He got in the elevator and he got off on the same floor that she did."

"Did he come back out?" Jack asked.

Sam shook her head. "No. And neither did Kate."

"What?" Jack pulled out his notepad. "That's a little odd, don't you think? Are there any other ways out of the building?"

Martin shrugged. "Doorman says there's a fire exit out the staircase, but the alarm never went off, so he doesn't think that the door was opened."

Jack nodded. That made sense, but someone who knew what he was doing could get around the alarm if need be – unless there was another way out of the building. Or unless the doorman was in on it, which was always a possibility. Jack had learned not to trust anyone. "Did he recognize the guy?"

"He said that he's seen him before," Sam said, "but he doesn't know his name."

"Okay," Jack said. "Good work. Sam, I want you to meet Viv at the vic's office downtown, see if you can get anything out of her coworkers. Martin, you come with me. We're going to have a little chat with the boyfriend."

Martin and Sam both nodded their understanding, exchanging the briefest of glances before Sam left to go meet Vivian. Martin looked at Jack. "What about Danny?"

"He's staying with the roommate."

15 Hours Missing

Jack parked in front of a Chinese restaurant and shot Martin a skeptical look. "Are you sure this is the right address?"

Martin pulled out the notepad where he'd written the boyfriend's address. He double-checked the information and looked at Jack. "This is the place."

There was a staircase around the back of the building, so martin and Jack clambered up to the second floor and made their way to the apartment number Molly had given them. Jack knocked. No one answered.

Jack nodded at Martin, and both men unholstered their guns. Jack pounded on the door. "FBI, open up!"

When the door still didn't open, Jack kicked it in, and he and Martin shuffled into the room, guns leading. Jack nearly dropped his gun in shock.

The apartment was completely empty. Not a piece of furniture, not a single picture, no belongings at all. It didn't look like anyone lived there or had lived there for some time. Martin lowered his gun.

"Well, this is weird," said Martin.

"I knew I had another picture of him somewhere," Molly said, depositing a very heavy photo album onto Danny's lap. She flipped it open and pointed to a picture. "Here. This is me, Kate, and Steve on Saint Patrick's Day last year."

Danny looked at the picture. Kate and Steve both looked highly intoxicated, both of them holding a beer in each hand. Molly sat a little off to the side. She looked thoroughly out of place, but damn fine in a tight green T-shirt that said Kiss me, I'm Irish. "Must've been fun for you."

Molly shrugged. "If I hadn't gone, Kate would've gotten wasted and made a complete fool out of herself." She rolled her eyes and headed into the kitchen. "Not that she didn't anyway, mind you."

Danny examined Kate's boyfriend, trying to memorize the guy's face. If he was a suspect, Danny wanted to know his character inside and out. He didn't have a shady look about him, but that didn't mean anything. He looked like the stereotypical fraternity guy, with those movie-star good looks and blonde hair with bleached tips. "How did they meet?"

"Some bar uptown. He spilled beer all over her."

"I'll have to try that sometime," Danny said, grinning.

"I'd like to think, Agent Taylor, that you have more tact than that," Molly said.

"Well, it obviously worked for him."

"Yeah, but Kate doesn't exactly have high standards." He heard Molly in the kitchen behind him, opening and shutting the cabinets, and craned around to see what she was doing. She was apparently making coffee. "Personally, I think she'll date any guy who shows an interest in her."

She glanced at him, and their eyes met briefly, before Danny turned back around. He didn't want her to think he'd been staring. "So you don't like this guy?"

Molly came around to the front of the couch, and he accepted the mug that she offered. "She could do better." She sat down next to him. "But she's done worse."

He turned to look at her and suddenly realized just how close to her he was, and how much their little domestic scene resembled a date – the two of them on the couch, drinking coffee and flipping through photo albums. Luckily, his phone rang. He stood up, thrust his coffee into Molly's waiting hands, shot her an apologetic look, and wandered down the hallway to answer the call. "Taylor."

"Danny." It was Jack. "We just left the boyfriend's place."

"What did you find?"

"Nothing."

Danny opened his mouth to respond but no words came out. He cast a wary glance at Molly and retreated farther into the apartment. "What do you mean, nothing?"

"I mean nothing." Jack sounded irritated. "Apparently the guy cleared off. No one's seen him since last night, and I've got five tenants who all saw movers emptying the guy's apartment." There was a pause, and Danny heard Jack mutter a muffled curse; he was probably stuck in traffic. "You still with the roommate?"

Danny nodded, even though Jack couldn't see him. "Yeah."

"Find out whatever you can from her about this guy. I want to know everything. Where he works, where he hangs out, who his friend's are, his cousin's college roommate's middle name – everything. Martin and I are going to rendezvous with Sam and Viv and talk to the vic's parents."

"Sure, Jack. No problem."

"Listen, Danny, until we know exactly what this is about, don't let the roommate out of your sight. She's either our best suspect or the next victim."

Danny gulped and leaned forward until he could see around the corner. Molly had curled her legs up underneath her and picked up the discarded photo album. She glanced up momentarily, caught him staring, and gave him a questioning look, then nodded at the phone. She wanted to know if they'd found out anything. Danny leaned back, so that Molly was out of sight again, and said into the phone, "Right, Jack. Got it."

He hung up and dug the heels of his hands into his eyes. This was going to be a long day.
