Ch.1

Castle woke up to the sound of his phone ringing. Groaning he rolled over and smiled as Beckett filled his caller I.D. he could really get used to waking up next to her every day. He couldn't remember feeling that way since Inara. No he shouldn't think about her it made his heart hurt. "Why if it isn't the extraordinary Kate Beckett." He said.

"We have a dead body on 50th and Lexington." she said smiling over the greeting she received.

"Okay I'm on my way."

Beckett looked at the victim in front of her. It was a white male in his early thirties. He had a hole in his chest that looked like it came from a knife. Lanie was kneeling next to the body examining the wound when Castle arrived holding two cups of coffee.

"So what do we got?" he asked handing Beckett one of the cups of coffee.

"White male stab wound to the chest." Kate filled him in taking the cup with a smile. "Do we know time of death?" Castle asked looking at the victim for the first time. He did a double take when he saw the victim. He knew this guy. His name was Atherton. "Are you okay Castle?" she asked when she noticed that he continued to stare at the body. "I'm fine." Castle lied not telling Beckett that he knew the victim.

Lanie who was examining the body turned to Castle. "Time of Death is approximately between 11:00 and 2:00 a.m. C.O.D looks like a stab wound to the chest. I'll know more when I get the body back to the lab." Detective Esposito walked up to the three people around the body. "After canvassing the area we still weren't able to find the vic's wallet." He told them. "Great so we have a John Doe." Beckett said frustrated. Castle was still shaken over the fact that he knew the person that he wasn't paying attention."Are you sure you're alright?" Beckett asked."Yeah" Castle answers snapping out of it.

"I know who you're victim is." Castle turned around instantly recognizing the voice. No! It can't be how did he get here, he was supposed to be back in the future with the rest of his past. "Hello my name is Shepherd Book."

Back at the precinct Castle and Beckett were watching the interview with the Shepherd.

"How do you know our victim?" asked Ryan.

"Well I don't really know him, but I know of him." replied the Shepherd.

"Can you tell us his name?" asked Espo

"Yes his name is Atherton Winng."

Castle wasn't paying attention to the interview; his mind was drifting towards Serenity. How did Shepherd get here? If he's here does that mean everyone else is here? Is Inara here? No! You can't do this to yourself Malcolm. No! You're not Malcolm your famous writer Richard Castle. Malcolm Reynolds no longer exists.

"What can you tell us about him?" asked Ryan.

"Me nothing, but you should ask Captain Reynolds."

"Who's this Captain Reynolds? Do you think he killed Mr. Winng?"

"I do not believe he killed Atherton, but you could always ask him. I mean he is watching this interrogation from that room." Shepherd pointed to the mirror from which Castle and Beckett were watching.

Beckett turned to Castle with question in her eyes. "What is he talking about?"

"Come on you can't honestly believe him, Beckett you've known me for four years when has anybody ever called Malcolm Reynolds." Castle replied nervously not noticing that Book never said his first name.

"He never said a first name."

"What?"

"He never said a first name Castle. So how do you know its Malcolm?"

"I thought he said a first name?" Castle said getting frustrated "Maybe I said a wrong name." Castle said hoping Kate would drop it.

No such luck. Kate knocked on the window stopping the interview. Ryan got up from his chair and walked out the door to the viewing room.

"Ask him the first name of Captain Reynolds." Kate said.

"Do you really believe his story?" Ryan asked.

Kate looked back at Castle who was sitting there pretending not to care. "I don't know."

"What's the captain's first name Shepherd?" Castle was silently freaking out. Please don't say it please he begged in his head.

"Why it's..." BOOM! The 12th precinct was shaking smoke was filling the hall ways. "What was that?" Demanded Kate as she walked into the interrogation room with Castle right behind her.

"I'm afraid there here." Said Sheppard

"Who's here?" asked Ryan as the three detectives pulled out there guns and pointed them at the door.

Ignoring the detectives he looked straight at Castle and said one word "Alliance"
