The Bet - A Castle Fanfiction

This is my first fanfiction, so no mean comments please. Critisim is okay though. I know this chapter is completly based on the case, but its setting up for what i'm going to do. I personally don't like stories all about the case but trust me, it gets better next chapter! And no, I don't own the characters, nor will I ever.

Chapter 1

"Where are we on Mich's aliby?" Beckett asked walking to her desk with Castle following her.

"He was at a party on the corner of 4th and Lex. We are wating for security camera footage," Esposito responded.

"Alright. What do we know about his brother?"

"He didn't do it," Castle quickly remarked as he sat down at his usual seat.

"And how can you be so sure?" Beckett asked as she quickly turned to look at him.

"He's a distraction. The killer has made him look innocent so that he is safe."

"Ah, and how do we know the killer knows Mich's brother?"

"Uh, he...um..."

"Exactly." Beckett smiled. Castle had great ideas that occasionally led them to the killer but at other times, they didn't make so much sense.

"Hey Beckett, we got something," Detective Kevin Ryan shouted from his desk.

Beckett got up from her desk and walked over the Ryan's where him and Esposito were standing. Castle followed, curious to see if his theory could be true. On his computer screen was a man's picture.

"Now he looks menacing," Castle stated.

Esposito gave him a look before stating, "Rob Bowerman. Our vic called him the day she was murdered."

"Let's go talk to him," Beckett said grabbing her coat and started to head to the elevator.

...

"And you just so happened to talk to our vic the day she was murdered!" Beckett yelled, sounding determined.

"Ok, ok. Calm down. She helped me a few years back."

"With what?"

"With my imprisonment. "

"How?"

"She got me 7 years instead of 10."

"What did you do for her? Why would she want to help you?" Beckett asked.

"Why not? She was a nice gal."

Beckett raised her eyebrows. "That's it? You didn't help her in any way?"

Rob looked down.

"Oh come on! Spit it out!" Castle yelled.

"Castle! Shh! Look Rob, I can get you more jail time if that's what you want."

"No!"

"Then fess up," Beckett said fiercely.

"There is nothing to fess up!"

"Are you sure about that?"

"Alright. She was an ex of mine. After what I did to her, I really don't understand why she would want to help me."

"An ex? Well, maybe she still had feelings for you."

"Look Detective, Rebecca was a nice woman. To anyone. To everyone. She forgave so easily it kind of made you feel guilty. She helped me out because thats just the kind of person she was."

"What did you two talk about on the phone?"

"She was panicking. Said that she was in trouble. I told her I couldn't help because well, obvousily im in prison."

"Why would she call you when she knew you couldn't help?"

Rob shrugged. "She resorted to me a lot. I don't understand why she wouldn't call one of her other friends. She had plenty."

"Did she have a current lover?" Castle asked.

Beckett smacked his leg under the table.

"Yeah, actually she did," Rob responded.

Castle slowly turned his head to Beckett and smirked.

"You know his name?" Beckett asked ignoring him and the fact that he got them another lead.

"Lucas...Lucas Phillips."

"Alright thanks," said Beckett as she stood up. She took out her phone and dialed Ryans number. "Ryan I need you to look for a Lucas Phillips...ok, thanks...we'll find him in the morning."

"Why in the morning?" Castle asked with great curiosity.

"He lives in Connecticut. Long drive."

"See you in the morning then." Castle said walking towards the street.

...

Knock. Knock.

"Lucas Phillips?" Beckett asked standing in front of his door with Castle, Ryan and Esposito. No one answered. "Go," Beckett motioned the boys to knock the door down and check inside.

The crew spread out into the whole house. Besides Castle, who went over to the coffee table in the living room.

"Clear!" Ryan yelled from the back bedroom.

"Clear!" Esposito yelled from the front bedroom.

"He's gone," Beckett said pushing her hair back as she looked around.

"What's this?" Castle asked looking down at a piece of scrap paper.

Beckett walked over to the living room and stood behind him. "Looks like he's headed somewhere." Beckett said as she took the scrap of paper. She then flipped it over to reveal more handwriting. "In the city."

"Hey, Beckett. Check this out," Esposito called from the other side of the room.

"A engagement ring? Looks like he was planning something big. He must be devastated. But why would he leave town?"

"Maybe he isn't as innocent as we think he is," Ryan called from the kitchen holding up a gun.

"9 millimeter...our murder weapon," Beckett stated studying the weapon.

"Hey, he's staying at a hotel on Madison," Castle called from the living room.

Beckett walked over and grabbed the paper that had the hotel name on it from Castle. "Let's go get him."

...

"I didn't do it," said Lucas.

"Then why did we find this," Beckett slid the murder weapon towards him, "in your home?"

Lucas' eyes widened. "I honestly don't know."

Beckett lowered her head. She slowly brought it up again and asked, "So you don't know why it was in your house? Or why you left town?"

"I know how you solve your case. The boyfriend always looks guilty."

"Yeah, especially one leaving town," Castle added.

"I had to get away, alright. My place gave me bad memories."

Beckett slid the engagement ring across the table. "Planning to propose?"

"I did."

"You already did? And she declined?" Castle asked.

"She said she wasn't ready for a commitment," Lucas shrugged.

"When did you ask her?"

"Three days ago. Why does it matter? Huh? She's dead and I didn't do it. You're looking at the wrong guy," Lucas said, raising his voice.

"Lucas, please. We are doing what we can to solve this murder."

"No. Your not."

"I think we are done here. Stay in the city for a while please," Beckett said leaving the interagation room with Castle following her.

"He's innocent," Castle stated.

"Yeah, well you know how I do my investigations."

Castle nodded and looked behind her. "Whats Motorcycle boy doing here? Well, man, i mean"

"Early dinner date. Night Castle," she said as walked backward and smiled at him.

Castle really didn't know what it is about that guy. Every since the fight in the hospital, he became to hate Josh. He normally did have such mean feelings to someone, but to Josh, he did.
