For some reason when season five started I've had this idea for a while and I decided to write it.

Both Castle and Beckett walked to the crime scene, coffee in hand as they both exchanged secret looks. Even dating for three months the new couple still liked to keep there relationship on the down low even when there friends already knew about them.

Making it to the crime scene which was an alley behind a restaurant the couple went pass the tape, giving a curt nod before heading over to Lanie who was currently examining the body. "Good morning Doctor Parish." Kate said smiling at her best friend before handing her coffee to Castle so she could put on her gloves. "So what do we got?" She asked before crouching down as well to get a closer look at the body.

"Victims name is Christina Mendoza, she's thirty seven and works at Davidson Law Firm." Lanie explained slowly.

"Cause of death?" Kate asked.

"Three gun shot wounds, two to the chest and one at her head. Looks like it's from a small caliber gun." Lanie said pointing to the bullet wounds. "I'm putting the time of death to 7 to 8 A.M. I also found this clutched in her hand." She finished taking the small evidence bag and passing it to the detective. It was a silver necklace, with a charm that was a mother holding a baby in her arms. "The necklace is probably an indictaction that she is a mother."

Kate examined the necklace before passing it to Castle now noticing his facial expression. His face showed seriousness and concentration almost as if he was trying to remember something he didn't even know. She'll take to him once they were alone.

"Beckett." Esposito called getting her attention as he walked to her. "I talked to the owner of the restaurant and he said that she was here this morning at seven thirty and looked nervous and scared. He said that she ordered a table for two but the other person never should and she left at seven fifty." Esposito said while reading over the interview notes.

"Ok well, once at the precinct check over her phone records and emails. I want to know who she was waiting for. Meanwhile Castle and I are going back to the precinct and inform her family if she has any."

The call ride to the precinct was quite and uneventful with Castle and Beckett lost in their own thoughts. The went up the elevator in silence and slowly walked to Beckett's desk and finally Kate broke the silence. "Castle are you ok, you've been quiet." She whispered, not wanting to leave there conversation out for other detectives to hear.

"I'm fine." He lied, looking anywhere but her.

"You're a bad liar, you know that." He shut his eyes and sighed before nodding his head. "What is it?"

"It's the victim." He said slowly, still not looking at her.

"What about the victim?"

"I pretty sure I knew her or met her somewhere." His eyes went to the murder board. Christina's picture in the middle. He tries to remember where he's seen this woman. Her dark eyes that looked almost black had a shine to it, her dark brown hair framed her face nicely and her tan skin had a glow that made her shine.

"Maybe you met her at a book signing or something." She suggested.

"Maybe." He said finally looking at her. Her eyes showed all the love and reassurance that he needed and maybe she was right.

The rest of the day the crew looking into Christina's phone records and ordered take out. By now it was almost six when Esposito, Ryan, Beckett and Castle finished eating and an unfamiliar woman walked into the precinct. Her eyes scanned the precinct and landed directly at Castle making him uncomfortable underneath her gazed as she walked towards him. "Mr. Castle." She said.

"Yes." He answered a bit un surely and watched as Beckett slowly walked over to them.

"My name is Rachel Lopez. I'm here to talk to you about Christina Mendoza" Rachel stated.

"Umm I don't know what I could do. I didn't know her." He glanced at Kate and could see the confusion in her face and honestly it's probably written all over his face too.

Rachel took a sheet of paper out her brief case and looked through the paragraphs. "Your name is in her will."

"It is?" Now it was getting weird. "What does it say?"

"It says and I quote "If I die I would like my daughter Skylar Mendoza to be given to her biological father Richard Castle.""
