AN: Again, thanks for the reviews so far! They mean a lot that I have readers enjoying my story :) I hope you enjoy the new chapter.

Kathie and Kate arrived back at Kate's apartment after dropping Castle off at the 12th. Kate had told him that she wanted to get Kathie checked out by a doctor to make sure when she tripped she didn't hurt her leg. They didn't go to the doctor though.

They locked the door, bolted it, and closed the window curtains before sitting down on the sofa.

"Alright Kathie...tell me what this girl looked like".

"Brown hair, cat like eyes, big lips, hazel...blue...eyes maybe...I couldn't really tell. She had a few tattoos that were exposed when the sleeves of her jacket moved".

"I'll see if I can search for some results when I get to the station".

"No, Kate. I'm not letting you research this...not without me. Remember...we had a deal".

Kate sighed. "What do you want me to do?"

"Call out for the rest of the day and watch stupid romantic comedies with me". She smiled brightly, which Kate returned. She picked up her cell phone to tell Esposito that she wasn't going to be in for the rest of the day.

After a few romantic comedies later, Kate had gone to pick up her dry cleaning and pick up some Chinese food for the both of them. Kathie was sitting on the sofa, typing some lesson plans when she heard the noise...the noise of glass breaking from Kate's bedroom.

She pulled the gun out from under the couch cushions. "You know it's not very smart to break into a detective's apartment..."

She waited for someone to show themselves and that's when she saw the face...the face of the woman that killed her mother. She was dressed in the trench coat that was longer than before and changed her jeans. "Well that detective isn't here at the moment. It's just us". She smirked like she did earlier that day.

"What do you want?"

"I want you to fear me".

"You do realize I am holding a gun...I can shoot you".

"But you won't. You want Kate to see me...you want me alive so she can slap the cuffs on me". She was right. Kate deserved to arrest her.

"What's your name?" Kathie lowered the gun.

"Well since you'll never find me and your time is almost up I might as well tell you who I am. My name is Anna Walker and I'm the leader of the gang that killed your mother. Back then though I wasn't leader, I was just joining and your mother was my victim".

"So it was just the wrong place at the wrong time kind of scenarios?"

"Basically. She was walking home and the guys saw her and brought her to that alley...well I don't want to give you all the details but you know how the story ends".

"Why'd you come back to the scene of the crime that night?" Kathie was trying to stall her until Kate could come back so she can shot the bitch that killed their mother.

"Because at the time I felt guilty. I was 19 and thought what I did was wrong..."

"You're damn right it was wrong! You took my mother away from me! Away from my sister! Away from my father!"

"No need to raise your voice at me Kathleen" She smirked. She obviously had no guilt now for killing her mother. "I knew you saw me that night. Not enough to recognize me...but enough for you to recognize me when I finally showed myself today".

"Why today?"

"Like I said...I want your fear. You're the next one I'm taking down. You'll never see it coming and neither will Katherine. Then once you're out of the picture I can take down little Katherine as well".

Kathie picked up the gun again and pointed it at her. Not showing any fear like she knew Anna wanted her to. Anna smirked. "You know you're pretty brave for a high school English teacher. You know if you weren't in my way I'd consider just taunting you for the rest of your life". She kept the same evil smirk on her face. "Until next time, Kathleen. Tell Katherine I said hi". She turned around to come out the same way she came.

Kathie knew she'd have no chance going after her. She had no shoes on and in a pair of Kate's sweatpants and sweat shirt. She wouldn't get far. She groaned in frustration as she sat back down on the couch with her head in her hands.

She knew who the killer was, she knew what she sounded like, and she knew what she was after but she just couldn't grab her.

Kate had just picked up her dry cleaning and was heading to pick up their Chinese food when she ran into Castle. "Castle do you always have to follow me?" She smirked.

"Well you know me, I'm like a lost puppy...just looking for an owner". She rolled her eyes as she entered the restaurant. "How's Kathie doing?"

"Better. We watched some movies, talked about a few things that weren't related to anything that happened today, and you know just sister stuff" She said as she went to the counter and told the cashier her name.

"Who's taking care of her dog?"

"Zeus is staying with her neighbor for the night" She looked over at him "Yea, it should be no shock that an English teacher named her dog after a Greek god. He acts like one too...but he's a lover boy at heart" She smiled.

"Well that's how most dogs, and even people, are. They act brave on the outside but on the inside they're just looking for a hug". Kate knew he wasn't talking about the dog anymore.

"Castle I'm..."

"Here you go Beckett. $25.60" The cashier handed the bag of food to Kate as she handed her the money.

"Keep the change". Beckett gave her a soft smile.

"Have a good night!" The cashier said as she put the money away.

Kate looked at Castle. "Did you order something?"

"No, I just wanted to make sure you two were okay".

Kate gave him a soft smile. It was nice having someone else care about her and her sister. "Castle, you can come over if you'd like to join us. I'm sure we have enough food". She couldn't believe those words came out of her mouth and by the look on his face he didn't either.

"Yea, that sounds...great. Thanks" He nodded as they headed out the door of the restaurant, after Castle insisted in carrying the bag of food, and headed towards Kate's apartment. They were just about to enter when Kate saw a woman dressed in a large black trench coat with long brown hair exit from the alley.

"Excuse me, Miss!" She said hoping she'd turn around.

Anna smirked when she heard Kate's voice but she kept walking away. She was sure Kathie would tell her about her visit once she got to her apartment.

Something didn't sit right with Kate about this. She walked towards the alley and looked down it, nothing seemed to be out of the ordinary. She couldn't just chase this woman down because she looked suspicious and wasn't answering to her. She sighed before heading into her apartment building with Castle.

"You know when people usually don't answer you they either are deaf or they're hiding something" Castle said as they climbed the stairs.

"I know...but I can't just tackle her to the ground to arrest her because she's wearing a black trench coat and coming out of an alley". She unlocked the door to her apartment and headed inside. This was when she was so grateful that Castle was holding the bag of food because she would of dropped it, just like she did with her dry cleaning, when she saw her sister crying on the sofa.

She ran over to her sister to sit down next to her. "What happened?" Kate wrapped her arms around her sister.

Kathie leaned into Kate. "She was here. I was typing, she broke the window in your bedroom, and then she came in here".

Castle set the food down on the table and gave them both a questioning look. Kate didn't tell him the reason why Kathie ran into the woods on the car ride home that morning. No one really said a word besides the voices on the radio.

Kate's expression went from worried to angry in a matter of seconds. That woman she saw in the alley was her mother's killer and the woman that had just broken into her apartment to get to her sister. "She didn't hurt you did she because so help me I will go outside right now and..."

"No, she didn't hurt me".

"What did she want?"

"Um...I know that this isn't really a good time to chime in but I'm a little confused on who this she is".

Kathie moved her head from Kate's shoulder to look at Castle. "The reason I ran into the woods today was because I saw our mother's killer. She broke into the apartment and left a few minutes before you got here". She then looked back at Kate. "She wanted to let me know that I don't have much time left and she wants me to fear her. Once I'm out of the way she's coming for you".

This made both Kate and Castle's mood change. "Did she tell you anything else?" Kate hoped that they could get to her before she got to her sister.

"Her name is Anna Walker. She is mom's killer and she's the lead member of a gang. Killing mom was the first step in joining the gang".

"She gave you her name!" Castle asked shocked that a wanted criminal would do that.

"She's very confident that she's going to kill me...but she won't. I'm going to find her first".

"Kathie..." They both said.

"No, I am going to find her before she finds me. I am not going to let her win and have her kill me. I'm going to be the one that gets to her first".

"Why don't you two stay at my house at the Hamptons for a few days. No one will know you are there besides me".

"Rick, that's a nice offer but we can't".

Castle really wasn't surprised when Kate had used his first name. He knew that this was serious and he was going to do anything he could to protect Kate and Kathie. "Then stay at my loft for tonight. Just until you can fix the window in the morning".

Kate sighed and looked at her sister who she was still hugging, so grateful that she hadn't lost her sister to the same person she lost her mother to. "Just one night, Rick".

"That's all I'm asking".

Kate got up from where she was sitting and headed to pack a bag for the night. Kathie looked at Castle. "Thank you. Not everyone is willing to take in two women that have someone out there wanting to kill them". She gave him a soft smile.

"Well your sister and I kind of having a thing for saving each other. I'm ahead of the game by one point so I want to keep winning" He smiled which caused Kathie to smile brighter and shake her head.

"Does Kate know you're keeping score?"

"Yes, she does and she insists that my math is wrong" Kathie laughed for the first time since, well since he had met her. It was a great accomplishment in his book.

"That sounds like Kate alright".

Kate came out of her room with a bag of her things for both her and Kathie. "What sounds like me?"

"Oh just that I've saved your life more times than you have saved mine and you won't admit to it". Kate rolled her eyes and Kathie smiled.

"Lets go before I change my mind".
