A/N: This chapter's a little bit angsty. After this there will probably will be two or three more chapters. Let me know what you think!

Chapter 12

"It wasn't easy, but I did it. First I went to the chess shop, where I bound George Newman in the storage space. After that I pretended to be the owner, I first shipped suspicion to that idiotic writer. That night I killed Alex Gruntel, leaving a message. The chess piece contained a fingerprint of him, and seen his history I thought it would be nice to make him the suspect first. Of course this all happened before I met you." Felix smiled at them.

"Anyway, I knew I wanted to get rid of George Newman as well, he was annoying. And then you showed up under my desk. When you were both unconscious I got your fingerprints all over the murder weapon I killed Alex with. After that I let a guy I know put it in the detective's house, since your keys were in your pocket it wasn't hard. Together with Bob we dragged you to the chess shop Bob is very good with tech stuff and disconnected all the cameras in the area. We held you up by your arms and let you lean in the shop first before disconnecting the cameras on the inside."

Castle's eyes grew wide at that. "That's… So smart." He said. He had to admit that even in his stories he wouldn't think of that.

"Thank you Mr. Castle. And as for your little escape tonight… You both lost your alibis. That way I could go ahead and kill my stupid ex. She broke up with me two months ago. But she couldn't just do that, she had to accept the consequences." Felix stared at the ground, motionless.

Felix looked up at them while they were both progressing what they'd just heard. "Okay, I'll leave you two alone for a second so you can decide who I'm going to kill." He said blankly.

"WHAT?!" Castle said, totally aghast.

"I think you heard me Mr. Castle. I'm gonna get rid of one of you and I'm letting you figure out who." Felix said and he and Bob walked out of the room and closed the door behind them.

"I will." Beckett said.

"Marry me? Sorry but now isn't the time…" Castle joked and then immediately turned serious again.

"No, I will be the one who's going to die." She said watching him as a horrified look spread over his face.

"No, you're not! If he's going to kill one of us it will be me." Castle said.

"No Castle! What about Alexis and Martha? Alexis needs you." She said. That one stung him, she could see it in his eyes. In the time she'd worked with him it became clear to her that Alexis was probably the most important thing in his life.

While he was trying to blink back his tears and keeping his voice steady he said: "She's strong. And you can be there for her. You know… I think she really likes you." His emotions were getting all mixed up right now. A small smile came across his face when he told Beckett that Alexis liked her. It was the truth, Alexis even thought Beckett was a good influence on himself, she'd told her.

"Castle you can't." Beckett said. She was trying to search for other things to say. "Felix will get the blame on me and then I go to prison, even if Alexis believes I didn't kill you, I still can't be with her."

The hurt was now evident on his face. "Kate don't… Don't say stuff like that. I will never let you die." As he said that he looked her in the eye. Then he thought of something that might convince her. "What about your father? He already lost his wife, would you let him loose his only child as well?" Castle knew his words hurt her but that's the only way to let her live.

Beckett looked away from his eyes and stared to the ground, not knowing what to say. "He was an alcoholic, right? Castle continued. "You were the one who saved him, if you're gone who knows what will happen. He needs you Kate." He watched a tear go down her cheek and brushed it away with his thumb.

"I need you." He said softly causing her to look up, once again, getting caught in his blue eyes.

"Castle I'm not letting you die. I can't live with that." She said and the door sprang open as Felix entered the room.

"So have you decided yet?" He said brightly, as if he were talking about picking out colours for wallpaper or a new couch.

"Yes" They both said in unison.

"Good, who is it going to be?" Felix said brightly.

"Me." Beckett said and stepped forward, being sooner than Castle.

"No, Me." Castle said as he pushed her back behind him.

"It's too late Mr. Castle, the lady was first." Felix said. "I was thinking of something less violent, like poison. That also does the trick, and I did promise I would make it quick."

This was the moment, Kate Beckett thought. She'd read about it in books and seen it in movies. The moment when you know you'll soon be dead. They always say you see your whole live flash for your eyes, memories of the past. But it was different, she didn't see memories. She saw what could maybe be her future. And the future contained a lot of Castle…

Castle looked at Beckett, as always she looked extraordinary. He couldn't let her die. He hoped Ryan and Esposito would be here soon. When they were in the car and weren't supposed to move, he very carefully had sent a text message to Esposito. 911 he had sent. That was the quickest way to make clear they had to hurry to trace the phone and rescue them. Felix had already destroyed the phones but hopefully they were able to trace the address before they did that. Otherwise Kate Beckett would soon be dead.
