Thanks for amazing response to the last chapter. Enjoy!

"Kate where are you I'm coming over."

"I'm going to Rick's apartment."

"I'll be right there; it's going to be ok." Lanie said gently whilst pulling on the first things that tumbled out of her over filled closet. Before she could even pull a thought together she dashed into the living room and grabbed her car keys and wallet off the table. Continuing her sprint she slammed into the elevator and pressed the ground floor over and over again in a desperate attempt to make the creaky old metals doors move faster.

Before she knew it she had driven herself to Castle's apartment building and was standing outside the door trying to convince the door man to let her in. "NYPD she's with me." Esposito said from behind her.

They ran into the elevator pushing the top floor button, as the doors closed realization began to sink in, Alexis was missing and the chances are the people who took her were the same people who tried to put a bullet through Kate's heart. These people weren't the same as the people she helped put behind bars everyday they are trained killers they are the masterminds behind Johanna Beckett and 5 other innocent people's murders. They are smart, and she knows that they can kill. "Javi, please tell me you have a lead or something, anything, just tell me you at least know where to search." She said as she started to pace back and forth rubbing her temples.

"I'm sorry, but at the moment we don't have anything."

"Is it connected to Kate's shooting?"

"We can't be certain, but the only reason we responded so quickly is because of her relation to Kate." He said solemnly placing his hands on her shoulders stopping her pacing so she was right in front of him.

"Javi, you will find her. Won't you?" Lanie said as her eyes began to water

He cupped her cheek and whipped away a lonely tear that ran from her eye. "I don't know, but I know that the whole of our team at the 12th and many more will be out there searching for her, and we won't stop until we do." He said pulling her against his chest into a deep hug, but all too quickly the elevator dinged and he let her go. He had too and as comforting as the hug was it was tinged with regret and fear of what was about to come.

The sight that met her as she walked out of the elevator was heart breaking. Cops covered the room like a flock of pigeons aimlessly pecking around avoiding the cat in the room, a washed up Richard Castle was sat on the sofa; worry was etched into his face like a permanent feature, it was hard to imagine that this man ever smiled.

"Kate you need to sleep." Lanie told her. They had moved their investigation to the precinct just before the sun rose, which meant that Kate had been awake for at least 25 hours and it was taking its toll on her.

"No I'm fine." Kate said brushing Lanie off and looking back at her scene. For the past few hours Kate and at least ten other cops had been going through any CCTV footage they could find.

"Kate, listen to me you need to sleep you won't be any help if you're not at your best."

"I need to stay awake, my boyfriend's daughter is missing and what if they find anything."

"If anything happens I'll wake you, if you don't want to go home then just sleep on the sofa."

"Fine." Kate said giving up she was too tired to argue.

"Hey." Castle said sitting next to Kate on the sofa as she just woke up.

"Has anyone found anything?" She asked sitting bolt upright ready to spring into action.

"No, no they haven't, she's still missing."

"Rick, we're going to get her back." She said stroking his cheek. "There's at last 50 cops working on the case."

"I... I can't help but imagine what they're doing to her, to my little girl."

"Just don't think about that, focus on her being safe and in your arms."

"But what if..."

"Castle no just focus on her being safe, we'll find her soon."

"Wait?" Javi said. "Lanie, the codes."

"What?" Lanie asked surprised.

"Yesterday you had a victim with numbers and letters written on them in marker pen."

"Oh my god, you're right."

"Do you have the photos?"

"Yes, there on the murder board."

"Wake up Kate. I'll go and get the photos."

"On it." Esposito said taking her orders.

"They just did a Caskett." Ryan murmured to himself.

"Kate wake up." Esposito said poking his head round the door. "Oh, sorry Castle I didn't know you were, umm here."

"Have you found anything?" Castle asked standing bolt upright.

"We're not sure, possibly, hopefully, remember the body that was found yesterday."

"The one with the numbers written on her arm?" Kate asked.

"Yes that one, Lanie thought it could be a code."

"Where are the autopsy photos?"

"Lanie's gone to get them."

"Let me help, please, I need to take my mind off things." Castle begged.

"Ok, Espo go and find out how the computer guys are doing, I fill Castle in"

"On it."

"Yesterday, we discovered the body of a girl in her mid-twenties, she had stab wounds that matched the pattern of a previous case... my mother's murder and then Lanie then discovered that on the underside of her arm there was a neat row of numbers." Kate explained.

"Codes." Castle interrupted. "Do you have any idea what they are?"

"We didn't look into it, we didn't have time."

"Here's the pictures." Esposito said entering the room followed by Lanie. The four pictures of the girls arm were dropped on the tale. A 12 digit number written in neat black marker ran from her arm pit to her elbow on each arm.

"Can we run them through data bases?" Castle asked.

"We have no idea what they are, it would be pointless."

"But can't we try? We might get something anything to help us find her."

"Castle I'm sorry, we all want to find her, but we'd be better off just staring at it and trying to find patterns."

"The number 99 comes up a lot." Lanie said half an hour later. "Does 99 mean anything too either of you?"

"It was the year of my mother's murder." Kate said.

"There dates." Castle realized "They're the dates of the deaths of the victims death."

"Wait I found something she said looking at the photo closely I think its another date."Lanie read out 082212. "That's a few days from now."

"They're planning a murder." Esposito added.

"It's the date they're going to kill Alexis."

Hope you enjoyed that please review! Sorry about any mistakes had to do a really quick read through.
