Chapter one: Another secret

(Kate Beckett walked through the elevator door into the twelfth precinct with a huge grin on her face. She and Castle had got rid of all the baggage, and started a no frills relationship of going out and then making love to one another whenever they had a break in work. She smiled softly as she remembered the way Castle had brushed her brunette hair out of her eyes and smiled softly at her, the only way Castle could…)

"Beckett" a sharp voice was heard and Beckett turned around to see Gates walking towards her

"Captain Gates" Beckett replied "Sorry I was pre occupied" she replied and Gates stared at her before nodding

"I see" she replied "Well don't be pre occupied anymore. Have you seen Richard" she glanced at Beckett who started to panic. She hadn't told any of the team yet about their relationship, because after Slaughters involvement she had nearly been suspended and Beckett didn't want anything getting in the way of her job. But also she didn't want to lose Castle either so he had agreed to stay away till she was ready to tell everyone

"Castle won't be here for a few months. He decided to go with Alexis to Stamford. Help her settle in" Beckett replied. Gates thought for a few moments and then nodded.

"I understand" she replied "Tell him next time you see Richard that the twelfth sends Alexis our best regards". Gates then walked away and Beckett let out a small breath. She then sat down by her desk and wished that Castle would come in to give her coffee. They always called that their good morning kiss but now they didn't need that anymore. Becket t blushed but then mentally slapped herself, Katherine Beckett didn't blush. However she thought about what happened between her and Castle last night and the thoughts were more than enough to let the blush creep to her face

"Beckett?" she heard a call and saw Ryan walking towards her "Got a new case. Stolen motorcycle"

"I won't be a minute" Beckett replied but then felt her stomach lurching. She winced and Ryan glanced at her curiously

"Beckett are you sure you are going to be ok?" Ryan asked carefully

"I'm fine Ryan" Beckett said sharply but then felt the vomit coming back to her stomach. She shook her head "Take Espo and you two go. Don't tell anyone" she replied. Ryan shook his head as he ran off to get Esparto while Beckett made her way towards a nearest bathroom. However Ryan had a better idea. Getting out his cell phone he made a quick call

"Laney its Ryan" he replied "Listen I think you better get to the twelfth straight away. Beckett isn't feeling too well. And I think she could do with a friend"

"Where`s lover boy" Laney replied but realised she had said too much silenced herself. Beckett had let slip one night while Castle was out at a book launch that she and Castle had slept together but Laney was the only person she had told "I mean where is Castle" she replied and hoped that Ryan would take the slip as her pet nickname for Castle as she had called him that a few times jokingly to Beckett.

"He isn't here Laney" Ryan frowned "He hasn't been around for a few weeks now. Has Beckett said anything about a row between them?"

"Not that I know of" Laney shrugged taking her gloves off "Listen I'll just finish here and I'll be down there quick"

"Thanks Laney" Ryan breathed and then hung up. Laney shook her head as she slipped her overall off

"Oh Kate what have you done. They might have to know now about yours and Castles relationship" she smiled to herself

"Kate?" Castle called out as he walked into his apartment. He smiled softly to himself as he thought of his girlfriend and despite the fact he couldn't call her his girlfriend officially he knew he would be able to one day. Castle got out his cellphone from his pocket and was about to dial her number when Martha walked into the room from her bedroom upstairs in the apartment.

"Richard!" Martha smiled "I heard you call Becket's name. You just missed her" she smiled at her son. Martha had caught the pair one night but promised not to tell anyone. Castle could see the look in his mother's eyes and knew she was thinking one thing. Finally

"So should I try the precinct?" Castle glanced at his mother who pursed up her lips

"Darling maybe you should give her some space. You two have been seeing each other pretty full on from what you told me the other day. And since her job takes a lot of her time up maybe see each other in the evenings when Beckett doesn't have a case on. Anyway I better get going. I have a lunch date" she smiled walking out of the apartment. Castle sighed as he sat down on one of the sofas. Maybe his mom was right but isn't what was supposed to happen when you got together, be full on. But he did that with his first two marriages and look at what happened there. Maybe Kate did need a bit of space. Castle shook his head and decided to go and work on some new ideas for the latest Nikki Heat novel. He smiled and let his mind go into his fictional world, until Beckett returned from the precinct

"Kate?" Laney said quietly making her way towards the door of the bathroom. The door slowly opened and Beckett peered out her face white

"Laney" she said quietly "I thought I told Ryan not to tell anyone" she moaned before going back inside to throw up

"He was worried about you Kate" Laney replied "So am I, Its not like you to be ill. Have you told Castle?" she glanced at her friend who shook her head

"No" she said weakly "It might be just a stomach bug. I-I can`t she replied quietly

"You need to know for sure" Laney said firmly "I'll go and tell Gates you aren't feeling well and that you need the doctors then you and me will go and" she stopped not wanting to say the words

"A pregnancy test" Beckett finished "It needs saying Laney but Gates won`t let me."

"Well she won't let you go out throwing up. Come on just give me a try" Laney smiled at Beckett and she nodded weakly. Laney just smiled as she exited the bathroom and made her way to Gates office

"How much longer now" Laney replied as they sat in Beckett`s old apartment. Luckily she hadn't sold it

"Two more minutes" Beckett replied as she paced around the bathroom her boots clip clopping on the tile surface. "Laney what if you know its positive" she replied "I mean an abortion I cant. But my career"

"Well we will jump that hurdle when we come to it" Laney replied "For all we know it might come back negative. You ready?" she glanced at Beckett who came out of the bathroom and nodded. Laney then grabbed her hand as the two friends made their way to the pregnancy stick and glanced at it. Beckett spotted a pink line that meant she was indeed pregnant. She didn't know what to do as she looked at the stick again. She knew she was happy but what about Castle. And what about her job at the twelfth.

"You know writer boy needs to know" Laney replied and Beckett nodded. She placed one hand on her stomach and gave a small smile. Hopefully everything would turn out fine.

"Laney I`m not coming back." Beckett announced

"Well I thought we told Gates that already" Laney said surprised

"I'm going to find Castle. I need to tell him" Beckett said firmly. Laney nodded as she walked out of the apartment and Beckett gave a firm nod before herself walked out of the apartment

Next time

Beckett finds Castle but can't find the words to tell him. Will Laney get there before him? Also Gates starts to smell a rat about Beckett`s lie about Castle being at Stamford and decides to investigate

Anyway that was the first chapter. Hope you all like it. Yeah the news is Kate is pregnant but there's a long way to go yet. Anyway please review and I'll try to update soon.
