They were half way to the precinct when Beckett's phone rang. She pulled it out of her pocket without looking at it and flipped it open. Not many people called her early.

"Beckett."

"Are you on your way to the precinct?" Esposito asked, his tone short.

"Yes. About half way there. Why?"

"They were able to decode the document on the CD Sydney gave you. You're going to want to read this."

"Yep, I'll be there soon."

"Ok."

She flipped her phone shut and chewed the bottom corner of her lip. Esposito didn't normally call to see if she was on her way. Whatever was on the CD must be pretty important. She hoped it would lead to the killer. They had no solid leads and it was really starting to get to her. She had to solve this one. She gripped the steering wheel and took a deep breath.

"What was that about?"

Castle spoke softly, but she was so lost in her own world that the sound of his voice made her jump. She looked at him and smiled shyly.

"Sorry. It was Esposito, making sure I was on my way. They were able to decode the CD. He said I'm going to want to read it."

"Great, maybe they'll be something helpful on there."

"God, I hope so."

Castle mentally sighed. He wished there was something he could do or say that would help her. He knew, short of solving the case, nothing was going to make her feel better. He also knew if she couldn't solve it, she would make it her fault. That she personally could have done something different, been better somehow. For someone as amazing as she was, she doubted herself almost constantly. He reached over and squeezed her hand as they pulled into the parking lot. She squeezed his hand back before letting go to get out of the car, but he could tell her mind wasn't on them anymore. She was already one hundred percent focused on the case before they had even walked into the building. Her passion is what gave her the drive to become a one woman tornado when she needed to be. He followed her into the precinct and knew he would do everything he could to be with her, every step of the way.

Beckett leaned back in her chair and ran her hand through her hair. She let her arms drop to the armrests and held onto them to stop her hands from shaking. Castle had moved his chair behind hers and had been reading over her shoulder. When she leaned back her shoulder was inches from his chest, her hair brushed against his cheek and it was all he could do to not wrap his arms around her and kiss the side of her neck. He settled for briefly squeezing the back of her arm, near her elbow. She sighed quietly and he moved his hand. To his surprise, she dropped her hand to his knee, absently running her fingers over the threads of his pants as she thought.

Beckett's mind was racing so fast she was having trouble keeping up with her own train of thought. She briefly felt Castle squeeze the back of her arm and she knew he was worried about her. She couldn't respond though other than to sigh, which he took the wrong way. She put her hand on his knee to let him know she wasn't upset by his touch. She intended for it to be a brief touch, but found herself lightly running her fingers over the material of his pants as she thought.

What they had read on the CD had been a digital version of Victoria's diary. She had written about finding out that her father wasn't really her father. It detailed how she had found out, when she confronted him, what he had said. It also held a darker secret. That her father had been giving his patients birth control instead of fertility drugs; basically forcing them into the next step in trying to get pregnant and going with in vitro. She detailed how her father chose which patients to do this too; they were always the ones with money. How he would pay the pharmacist at his building to change the drugs. Half up front and half when the couple actually had in vitro. She wrote that she had found all of this out by volunteering at her fathers office for a school project. She got nosy when she was organizing the file room and took it farther by going through private files in her fathers office.

They read for pages about her very emotional decision to confront her father about it. She wanted to tell him everything she knew and give him a chance to come clean and fix it before she went to the police. She mentioned even going as far as making copies of the patient files so she had proof. Much to Beckett's dismay she never wrote about where the files were. Her last entry had been about two weeks ago, before she had told her father what she knew. She never wrote about his reaction, or whether or not she even told him. The timing made sense. Sydney had said that Victoria gave her the case with the CD in it about a week ago. She would have needed time to make copies, have someone code them, and put all the file copies on a disk as well.

Beckett sighed heavily as she rested her forehead in the palm of her right hand. Her left hand still rested idly on Castle's knee. She pulled her hand down the front of her face until her chin was resting on her palm. She gnawed on the nail of her index finger as she thought. All they had now was more motive, a likely suspect and still no clues or proof. She wanted to scream.

Castle sat, unusually quiet, behind her. She knew she should say something, but she couldn't figure out what. Her mind kept spinning about what was on the disk, and where the other one could be. She had a strong gut feeling that Haven had it, or at the very least, knew about it. But she knew the girl would be reluctant to talk to her again. She was in the middle of a train of thought when Esposito walked up. He stopped next to her desk, in the space where Castle's chair usually sat, and raised his eyebrows, looking pointedly at Beckett's hand on Castle's knee. She slid her hand back to the armrest of her chair.

"Am I interrupting something?"

"No." "Yes." Castle and Beckett answered in unison. Beckett glared at Castle but she only half meant it, and he could tell. She crossed her arms in front of her chest and looked at Esposito.

"What ya got?"

"Well, the shoe print on the rug…size ten and a half. Victoria's father? Size ten and a half."

"Great. The most common shoe size for men in America. That will really narrow it down."

"I'll skip over asking you why you know that. You're right. But, the tread pattern is from a custom shoe maker. Someone Victoria's father just happened to buy shoes from six months ago."

"Well…that's better. But all that does it put him at the scene. Which isn't really that surprising considering he is her father. We need something more solid or we're never going to get this guy.

"What if he confessed?" Castle asked. Beckett and Esposito both turned to look at him. It was Beckett who spoke first.

"What, you think he's going to just admit to killing his own daughter because we ask him to?"

"Well…no. But what I'm asking is…if he confesses, would you still need proof?"

"It would be helpful for trial, but no. Confessions are usually pretty cut and dry cases, why?"

Castle thought for a minute. "Then we have to find the other CD, with the copies of the case files."

"Why…" Beckett asked again, trying to get inside his head.

"Because, we have to find something to break him with. If we have the whole story, the whole reason why he felt the need to kill his own daughter, sitting there in front of him, hopefully he'll crumble." He looked back and forth from Esposito to Beckett. Esposito was slowly nodding. Beckett was shaking her head slowly.

"That's assuming he even did it. We still don't know that for sure." Her stomach churned at the thought of a parent killing their own child.

"What she knew, what she was going to tell everyone, would have cost him his business, his license, jail time, everything. People have killed for a lot less." Castle reminded her quietly. Her eyes met his and he could see a sadness in them that he'd never seen before. It was brief, and by the time he blinked it was gone.

"Alright, so we find this CD, and then what? How are we supposed to get him to confess?"

"You bring him in here, and lay it all out in front of him. If any one can do it Beckett, its you."

"Sounds like we need another trip to visit Haven. Castle…you might have to be the one to get it out of her. She really hates my guts."

Castle tried to keep the shock from showing on his face. She rarely asked him for help so directly. She smiled at him, then turned to Esposito.

"You and Ryan go talk to Sydney again. She'll let you search her room. Go to Trevor's too. We searched his room when we were looking for the cell phone, but we didn't know what else we should be looking for. Call me if you find anything."

Esposito nodded and turned to find Ryan. Beckett got up and grabbed her jacket. Castle stood up next to her.

"You ready for this?" She asked. He nodded. "Good, because I have a feeling we're only going to get one shot with Haven. No pressure." She laughed lightly and elbowed him in the side. He smiled, glad to see her with a sense of purpose. Her moods when there were no leads on a case could border on unbearable.
