A/N: Thank you so much for the reviews and follows, I really liked to see people like this story :)

Enjoy reading now ;)

Chris was sitting in the interrogation room looking rather bored, she didn't know for how long she'd sat there already but it sure felt like it was too long. As soon as Esposito had arrived at the precinct he'd taken her into the room, leaving her there for Beckett to interrogate. However that wasn't really what Beckett had planned, she actually wanted to let the girl have some time to think about what she had done, maybe this way Chris would be a little more willing to cooperate.

Even though she had arrested the girl officially for the murder Beckett was quite sure that the girl had nothing to do with that, but that was something Chris didn't have to know right away. This girl had no respect for others and was so full of herself, it was time someone taught her a lesson and Kate Beckett was more than willingly to do so.

Castle stood with her in the observation room, watching Chris intently for what had already been half an hour. Most of the time his thoughts had been spinning around the little encounter between the two woman in the victim's appartement, they seemed to be pretty similar. Both, Kate and Chris, were tough woman, knowing exactly what they were doing. Kate had certainly been acting like the girl when she was at that age, he thought and therefore did't understand why she seemed to be really pissed off by the way Chris acted.

"Why are we just staring at her again?" he broke the silence between them.

"We're not staring, we're just giving her time to think." Beckett stated not moving her eyes off the pane.

"Well it pretty much feels like you're staring at her..." he watched the girl again inside the interrogation room. Chris was eying her fingernails carefully as if she wanted to demonstrate how bored and unimpressed she was by Beckett's little game.

Time passed in which neither one of them said another word, both were again deeply in their own thoughts. Castle trying to find out what made this whole thing between his girlfriend and the girl so fascinating, after all he'd seen Kate interact with many suspects but this, right here, felt different.

And Beckett trying to figure out what to do about the other situation at hand, the apparent relation of Daniel Morrison to Castle's daughter. Hiding it from him made her feel like she was lying and she didn't want to. Lies are what break people apart, if you're in a relationship with someone you love, and she really loved Castle, you should be able to trust your partner and he should be able to trust you. You don't lie to the people you love. But you also protect the people you love, so what if you can only protect them by lying? That really was a huge predicament.

She didn't feel comfortable with lying to him, she'd never been the type to tell people she loved Lies. But lately she found herself keeping things from her friends, she'd lied to Ryan and Esposito about her relationship with Castle, not to mention Lanie, her best friend. So why stop hiding things now? Right because it was Castle, she couldn't lie to him. She'd done that before, pretended she didn't knew about his feelings for almost a year, and it had almost driven them apart. Who knows if they'd overcome it a second time. No she definitely had to tell him, but not now. First she had to talk to Alexis, just a talk, not an interrogation.

"Doesn't really seem like your plan is working..." Castle spoke again slowly.

"No it doesn't..." she had to admit begrudgingly. "So what are we going..." he started to ask but when Beckett cut in he realized she hadn't been paying attention.

"How can some young woman be that calm when she's been arrested for murder? She doesn't even seem to care. She just sits there provocatively as if she wants to challenge me." she exclaimed clearly not understanding what might be going on in the girl's head.

"She doesn't know you're watching her, she can't be challenging you." he felt the need to clarify that.

"I know she cannot see me! But she's just so..." Beckett was searching for the right words to describe Chris but found nothing that fitted.

"frustrating?" Castle offered knowing exactly what she was talking about.

"Yes, frustrating!" she said thankfully.

"So..." he wanted to know what she was planning on doing now.

"We'll go in there now, let's see how calm she'll be then..." she smiled confidently, being sure she'll be able to unsettle the girl.

Although Castle wasn't so sure about that, after all she hadn't really managed to intimidate her up to now, neither in the appartement nor here in the precinct by letting her wait. But he decided it was best to keep his mouth shut and follow her into the other room.

When Beckett walked into the room followed by Castle Chris didn't even bother to look up from her perfect manicured fingernails, she seemed to not care at all.

"Oh was watching me suddenly not so interesting anymore?" she suddenly said still not looking at them before the couple could sit down.

Both of them looked shocked at her as if they'd been caught but on Castle's side was also a little amusement noticeable. This girl was good, how did she know? She had caught Beckett off guard, this interrogation just got even more interesting. He was curious what Beckett would reply and eyed her out of the corner of his eyes. She stood there frozen for a few seconds, she certainly hadn't expected that but soon got back to her pokerface.

"I'm detective Beckett..." she told the girl as she sat down not averting her eyes from Chris.

"Oh I know who you are..." she still didn't look at her, showing again how little respect she had. Castle slowly sat down next to his girlfriend, amazed by the calmness Chris apparently had.

"I'm really sorry you had to wait." Beckett lied.

"Cut the crap, you're not." finally Chris looked up, her eyes full of arrogance. Castle looked from one woman to the other, sensing that this outburst wouldn't go without Beckett getting pissed.

"Okay you're right, I'm not. You'd even deserve to wait longer but..." and there it was, she didn't shout or something, no her voice had a bitter-sweet sound and was way too calm. Castle knew that this voice meant the girl should run, his girlfriend was about to get really angry and an angry Kate Beckett was the least you want to face.

"But it drove you crazy, that it didn't bother me." Chris interrupted her to finish the sentence, smiling superiorly.

With every second Castle watched the girl he got more amused, Beckett exploding was certainly just a matter of time, this girl was playing with fire and had no clue how dangerous it was.

"You think you're clever..." Beckett eyed the girl with a slight smile on her face, she would show her that messing with her was a bad idea.

"Well I'd say I know I'm clever..." Chris was very self-confident, a little too self-confident in Castle's thoughts but he found it just great. Watching Beckett and Chris here in this interrogation room was like a game, two predators circling around each other, each of them confident to win. This was better than any tv-show and seeing Beckett like that somehow turned him on, she was so incredibly sexy right now.

"Being caught in Mr. Morrison's appartement searching for something after killing him actually doesn't seem so clever to me." Beckett mentioned looking Chris directly in the eyes, trying to find a hint that the girl felt guilty but she had no luck.

"There's just one catch to your little theory Princess, I didn't kill him!" did she just call Beckett princess? Oh this just got better, Castle thought.

"For you I'm still detective Beckett!" she clarified, her voice was icy.

"Yeah sure detective..." the girl rolled her eyes clearly still not seeing how serious the situation was.

"So you've been informed of your rights?" she was in her usual interrogation mode again, completely in control, not showing any emotions.

"I guess the hot detective mentioned something like that..." did she try to provocate her? Castle was sure the girl knew what effect her behavior had on Beckett, she was too clever not to know.

"Detective Esposito." she told her not giving away that she got more angry with every time Chris opened her mouth.

"That's his name?" she smiled mischievously, knowing it would drive Beckett nuts.

"Do you want to tell me your full name now?" the detective chose to ignore the remark, she knew she had to stay focused, even if it was kind of hard to do.

"No not really..." Chris shook her head slightly grinning at both Castle and Beckett.

"Why were you in the appartement?" now the interrogation finally began.

"I was looking for something." did she really think they hadn't figured that out already? Of course not, this was just another proof of how arrogant the girl was.

"And what was that?" Beckett questioned further, looking straight into the girl's blue eyes to intimidate her but without any luck. Chris didn't seem to be impressed at all by Beckett's look, which didn't occurs that often because most people couldn't stand that look. Castle himself hoped to never in his life get one of those looks from his girlfriend.

"Nothing you should care about."Chris didn't back away but looked back at her with the same intense look she received from the detective sitting across the table.

"Well I'm a detective, it's my job to care about it. So what was it?" Beckett started to get impatient, this little game got more annoying with every word Chris said and the fact that she still had no clue what Alexis had to do with this whole case made it even worse. She definitely had to know what was going on here, after all she was lying to the man she loved, but Chris seemed to be rather unwilling to help.

"A picture." the girl said simply, still holding the eye-contact.

"A picture of what?" Beckett asked hoping to finally get something important out of her.

"Me and Daniel."

"And how did you know Mr. Morrison?" now this interrogation took finally the turn Beckett had hoped it would.

"He was my boyfriend, that's also why I got the key. So looks like you've got nothing on me..." Chris seemed to be really confident of her victory and showed her the key, which she'd had in her pocket.

"You seem to forget I arrested you for murder..." Beckett told her happy to erase the self-satisfied grin on the girls face.

"Oh I didn't kill him and you know that... but in case you were wondering I've got an alibi, I was on a party at the Columbia University, all night." as Castle had thought the girl's grin didn't disappear but grew even wider when she informed Beckett of her whereabouts for the time Morrison was killed.

He watched his girlfriend closely, trying to figure out what was going on in her mind. It seemed to be hard on her to face such a strong young woman, who resembled her in so many ways, not only her strength and mimic but also her cleverness. If Castle hadn't known better he would have thought the two woman were somehow related to each other.

"So if you don't mind I would like to go now!" with that the girl stood up and walked towards the door. Beckett was just about telling her to sit back down as Chris turned around having the self-satisfied smile on her face she'd had before.

"Oh and just to satisfy your curiosity, my name is Crystal Brooks." she winked at Beckett and was then out of the room before she could say a word.

Actually Beckett didn't even know what to say, there was nothing she could have kept Chris under arrest for, she'd had a key to the appartement and apparently she got an alibi for the time of the murder, which didn't surprise Beckett, she still didn't know what the motif of the girl could have been but still she would check if Chris had told the truth.

"You're letting her go just like that?" Castle asked surprised, he'd actually hoped for a final showdown between the two woman. Imagining his girlfriend showing this arrogant girl how much power she had by keeping her under arrest had somehow something arousing.

"Even though I don't like it, I have to... we've got nothing indicating that she actually killed Morrison..." she told him frustrated.

"But we know they knew each other..."

"Yes but there certainly are other people who knew him too, I can't arrest them all." besides his daughter was also one of the people, who'd known the victim. She would have to arrest her too, which made Beckett feel sick. She couldn't just arrest Castle's daughter but still that photo Ryan had found was a strong motif. Even if she'd wanted to keep Chris under arrest she had to admit that at this point even Alexis got a better motif than her.

"Right... but can't you keep people for a certain time although you've got no proof of their guilt?" Castle suggested.

"Yes I can but I'm sure that would've led to many problems. She seems to come from a wealthy family, I'm sure the best lawyers of New York would've come to get her out of here." Beckett explained hoping her boyfriend wouldn't notice that this wasn't the only reason for letting the girl of the hook.

"But she definitely would have deserved it..." he had found the girl as unfriendly as his girlfriend had done since they met in the appartement.

"You think?" she gave him one of her typical Beckett glares, she just couldn't believe he found that out just now.

So that's it for today, I hope you liked this chapter... and hopefully you'll let me know what you're thinking ;)
The next chapter will deal with the conversation between Kate and Alexis, anything you'd like to see in there? Any ideas how Alexis knew the victim?
