Disclaimer: Yeah, all I own is Houghton.

A/N: This is set in the year 2013, but other than Beckett and Castle dating, it really doesn't go with the story line of the show, except for what we know already from past seasons. It has NOTHING to do with Season Six because I'm not a fan of spoilers.

It was a blistery, December morning and Alexis Castle was meeting Miranda Storme and her 8-year-old daughter, Houghton, at 10 O'clock at the university library. Alexis was in the Big Brother, Big Sister Program and Houghton was her 'Little Sister' and she absolutely adored her. Alexis was giving Houghton a tour of the campus of Columbia University since Houghton had been begging her too. Most of the students were gone for the Holidays since it was in between Christmas and New Years, so it seemed like the perfect time to do it without the young child getting scared by all the people.

As Alexis reached the library she heard Houghton calling out her name. Alexis smiled and pulled her jacket tighter around her as she went over to the mother and daughter, "Hey guys.." She smiled as she fought back a shiver. "What do you say we get this started so we can go to the loft afterward and get some hot cocoa?"

Houghton smiled brightly as a gust of upward wind blew, and she opened her mouth to agree when she heard a 'pop' and her mother let out a scream and collapse to the ground with an icicle sticking out of her chest, and a pool of blood forming around her. Alexis grabbed the child and ran into the library, hopefully out of harms way. Seeing dead bodies with Dr. Parish was one thing. But actually seeing someone get murdered was down right horrible. She ducked herself and Houghton into the bathroom and tried to keep the little girl calm as she hit a number on her phone and listen to it ring, "C'mon... pick up..."

"City of New York, 12th Precinct, how may I direct your call?"

"I need to speak to Detective Kate Beckett, on the Homicide floor please. It's an emergency. Tell her it's Alexis Castle."

"One moment please." Alexis was put on hold. She knew that if there was an emergency she had to call the precinct and not Kate personally. It seemed to have taken forever for her to get transferred when she finally heard a familiar voice on the other end.

"Detective Beckett's desk."

"Dad? Where's Beckett?"

"Alexis? Are you okay?" Richard Castle clearly had concern in his voice at hearing his daughter on the phone. Alexis rolled her eyes when she heard Beckett snatching the phone from her dad and asking how many times she told him not to answer her phone.

"Beckett."

"Kate... Its Alexis... You need to come to the university. There has been a murder."

"Are you hurt?"

"No, no, I'm fine but it happened by the library and I'm not sure if the shooter is still there."

"Where are you?"

"In the library bathroom." It was clear that Alexis was shaken and her voice wavered as she spoke. "Please hurry Kate."

"We're on our way Alexis. You hang tight in there and don't come out until I come get you." Alexis nodded even though Kate couldn't actually see her. "Bye Alexis." Alexis let out a whisper Kate couldn't make out before Alexis hung up her iPhone and held onto Houghton, trying her best to calm her down. Houghton was quite hysterical, as expected, and Alexis just did not know how to help her so she just held her and waited for Detective Beckett and the rest of her team to show up. All she kept thinking about was what kind of machine could shoot an icicle? Her dad was going to get a kick out of this one that was for sure.

Kate Beckett was in the break room making a cup of coffee when she was positive she heard her phone ringing. She walked out in time to see Castle scooping up the receiver and speaking very professionally into it, "Detective Beckett's Desk."

Kate made a face and walked over to her desk, "Castle! How many times do I have to tell you not to answer my phone?" She snatched her phone away from him, "Beckett." Her face crinkled when she heard Alexis on the other end of the line and she glanced at Castle for a second, "Are you hurt?" Kate nodded a little, motioning Esposito and Ryan to come over, "Where are you?" She nodded again while listening to Alexis and wrote down 'Murder' on a piece of paper and showed the boys who nodded. "We're on our way Alexis. You hang tight and don't come out until I come get you." It being quiet on Alexis' end she heard sobs, which she figured was Alexis, "Bye Alexis."

She placed the receiver down and looked at the boys, "Alexis said there's been a murder at the university at the library. She's also not sure if the shooter is still there or not so be on the look out as soon as you get there. I want vest on before we even leave the parking garage downstairs." She looked at Castle, who was very uneasy in his chair, "She's fine Castle. She said she wasn't hurt." Rick nodded a little and got up so they could leave. Kate texted Lanie - Body drop at Columbia University, Alexis is a witness. KB.- She tucked her phone into her pocket as they all bundled up to head out into the blistery December air. Whatever laid ahead for them in the next few hours, her partner didn't seem easy about going to his child's school. Which she didn't blame him at all.
