A/N: First, thank you all for following this story and reviewing…I hope you enjoy this next chapter!

The loft was quiet, when Castle walked in. Not that he minded anyway, he could use some time alone. Castle wasn't sure if what he'd done was right, but in his mind it was better this way, since he could have some control over the situation. He was so absorbed in his own thoughts he didn't hear Beckett in his study as he walked in.

"Care to tell me where you've been?" Beckett asked raising an eye-brow.

"Geez!" Castle yelped startled. "Beckett what the hell?"

"I could ask you the same thing Castle." She said seriously. "You leave, with no explanation and don't come back until 2 in the morning!"

"Oh, I'm sorry, I didn't know I had to check with you everything I do!" Castle replied loudly. They fell into an awkward silence. Castle let out a sigh and approached Beckett, who kept looking at him severely. "I'm sorry." He said running a hand through his hair. "I was at the Old Haunt." He lied.

"I'm sorry Castle…it's just that this case…seems to have a particular effect on you." Beckett explained as she let Castle sit her on his lap. "And I just wanna know why."

"You mean you want to know how I knew about the missing kidney." Castle said. Beckett just remained silent. "It was research. An idea I had for a novel, when I was working with Sophia Turner."

"Oh…" Beckett finally understood. "Sorry…I shouldn't have acted that way."

"Being a little possessive Detective Beckett?" Castle raised an eye-brow in amusement.

"In your dreams." Beckett rolled her eyes, but leaned into Castle's shoulder.

"Look at my life, my dreams come true."

But Castle didn't receive a phone call that night or early in the morning. It was almost noon and Castle and Beckett were at the precinct filling the timeline on the board. They were waiting on Ryan to pull the victim's financials, and Carson's ex-wife to come. Although Castle tried to act normal, he seemed anxious about something, he kept checking his phone more than usual and kept rearranging thing on the murder board.

"Castle, could you stop with the anxiety and tell me what's wrong already?" Beckett said annoyingly.

"I'm fine Beckett, nothing's wrong." But just when Beckett was gonna respond, Ryan came in.

"Guys I got something." Ryan was holding a brown file. "So, most of Mr. Carson's credit cards were maxed out, with his job he barely made enough to pay his rent, not to mention child support after his divorce. Yet, the interesting thing is that he had enough cash to spend most of his nights at clubs."

"Let me guess, Hour 50?" Beckett said.

"Yeah and another one in midtown call 'Theathron'". Ryan replied.

"Theathron?" Beckett asked.

"Is a gay bar." Castle answered absently. "One of the most exclusive in fact."

"What about his financial transactions the night he died?" Beckett told Ryan.

"He was at Hour 50 until a little passed midnight that night, and then he requested a cab up to the hotel."

"Was he alone?"

"No." Esposito said as he joined them. "I checked the security footage from the hotel and he came with a woman named Sheylin Dawson, but this is were it get interesting…" Esposito pulled out a photo of Sheylin Dawson and put it on the murder board. She was blond with green eyes and a certain exotic look. Castle remembered her immediately from a few hours ago. A pre-law student at NYU. "He checked in for another room, not the one where we found his body."

"Where's Sheylin Right now?" Beckett asked.

"I can't find her, I spoke with one of her friend, said she hasn't seen her." Esposito answered. Before Beckett could say anything, Officer Hastings came in with a woman.

"Beckett?" Hastings said.

"Yeah?"

"This woman says she's here about Mr. Carson."

"I'm sorry and you are…?" Beckett asked the woman.

"I'm Lindsay Conrad, Thomas' ex-wife."

"Ms. Conrad, thank you for coming, now when was the last time you spoke with Mr. Carson?" Beckett asked as she, Castle and Ms. Conrad sat at the break room.

"It was about too weeks ago, he called me…say he needed help."

"Help how?" Beckett followed up.

"He told me he was attacked and was at the hospital, but didn't tell me what happened exactly."

"Sounds like you had an amicable divorce Ms. Conrad." Castle said.

"I guess you could say that." the woman replied with a little sadness in her voice.

"What were the circumstances of your divorce, if you don't mind me asking?" Castle inquired.

"Other than economic problems, it was more the fact that he didn't love me in the same way I did."

"How so?"

"He hid his own identity from me."

"You mean his sexual orientation." Castle concluded. There was an awkward silence.

"Yeah…." Ms. Conrad answered with regret.

"When did you find out he was gay?" Castle asked.

"Well towards the end of our marriage, he started frequenting this place….uhmm…Theathron I think it was call…and it's a gay bar." Ms. Conrad frowned. "Which is weird because he didn't have the money for such nightclub."

"Ms. Conrad, his financial showed that he not only went to Theathron, but also a place call Hour 50, do you know anything about it?" Beckett asked quickly.

"No, and as I said before, I don't know how he did it, having to pay for child's support as well as his other stuff, he had to be in some kind of other job." Ms. Conrad said and then her phone buzzed. "Uh….I'm sorry is my son, I need to go."

"Off course Ms. Conrad, thank you very much for coming." Beckett said standing up and shaking the woman's hand. "If there's anything you think might be relevant to our investigation, please give me a call." Beckett handed her one of her business cards.

"Thank you detective. " Ms. Conrad headed to the door. "One more thing, I just feel the need to clarify."

"What's that?" Beckett asked.

"I don't want to get you the wrong idea that I divorced from Thomas because he was gay, I did it because he didn't trust me enough to tell me he was." With that Ms. Conrad left. Once alone, Castle started to make Beckett some coffee.

"So he contacted her after his kidney was stolen." Beckett said. Castle remained silent. "Castle?"

"Uhmm?" Castle looked at her distracted. But before Beckett could say anything else, Esposito came in.

"Yo, we got Sheylin Dawson."
