The notebook

"So, I found it the other day when her mom was going through her stuff." Sam says holding a red notebook.
"I don't want to mess with her dead spirit." Lisa replies.
"Come on, maybe she wrote something down that could help with the case."
"Then give to the police, Sam."
"But we're her friends, we should read it first. Make sure she would be fine with us giving it to the police."
"And, what would be the point?" Cuts Lisa."She is dead."
"Then, it makes no difference."
"Fine, read it," she says as she stands up.
"Where are you going?" Asks Sam.
"I'm not going to be a part of this."
"You make it sound like I'm planning a murder."

Bad joke. Really bad one

"Okay, then tell me if you find something,"says Lisa "I'm not wasting my time on this." She storms out of the room, leaving Sam with the notebook.

Sam keeps reading the notebook while crying, or fake crying that's what Lisa thought.
Lisa could hear Sam flickering the pages, gasping, cursing. As if she was reading a crime novel and enjoying it.

While Lisa went through their old pictures, Katie's clothes, the gifts and all the social media accounts that belonged to Katie, Sam kept reading.

"You didn't even move a muscle" says Lisa.
They were both now, sitting at the couch in the living room.
"Not true," she says, not taking her eyes off the notebook. "I move my hand to flip the pages."
Lisa sighs and smiles to herself, but doesn't give Sam the satisfaction of seeing her smile.

She was still angry at Sam.
She needed to be angry at Sam.
At someone.

"Besides, there are some cool shit in here," she says "like did you know she shoplifted when she was 15 for money?as in a job." They both laugh. "Or that she colored her hair green because her crush, Antonio liked an alien in a movie," Sam bursts out "she didn't even know which movie it was." Sam keeps laughing, but Lisa shakes her head and says "that is extreme."  Then smiles.
"Oh oh wait, this one's good," she says "she and her mother wanted Alison and her crush to go on a date so badly," her voice was getting full of excitement "they even kind of threatened him."
"Wait," Lisa cuts her "Alison didn't show up at the funeral."
"Oh, that's probably because Alison screwed up Katie's dream job interview on purpose, and also got her expelled from college because she was jealous," she says as if it was nothing. "Oh, another thing we didn't know." She smiles to herself.
"But, why didn't she tell us?" Lisa asks "she made Alison look like a sweet sister".
"Maybe she is."
"Sorry, but I have a hard time thinking that sisters who screw up their sister's lives on purpose and don't show up at their funeral are sweet."
"Then maybe that's how Katie wanted to think of Alison."
"Katie was so good," she takes a deep breath "she didn't deserve that."
"She is in a be..."
"Don't you dare finish that."
"Oh my god!"
"What?"
"Shit shit shit shit shit."
"What is it Sam?"
"Bloody hell."
"Tell me."
"Let me make sure first."
Sam read a few pages then looked over the top of the notebook, her eyes wide, mouth open and said.
"Oh god, I think I know how she got killed."
"Lord, what is it Sam?"
"She worked as a prostitute."
Lisa laughs "no, she didn't," she says "she worked in the bakery with Denny."
"Yeah, but she also had sex with men for money."
"No way," she says "she is the last person who would do such thing."
"Why is it because she looks so pure and innocent?"
"Looked" says Lisa firmly.
"You'll be fascinated by what's hidden behind people's looks."
"Don't talk about her like we didn't know her."
"Looks like we didn't..."
Lisa shakes her head. "She was our friend," her voice getting higher "don't you think we would've known if she worked as a prostitute."
"That's her handwriting, here take a look for yourself"
She takes the notebook and reads a few pages.

This does make sense. It explains a lot, Lisa thought.
That would explain her break up with John, because I knew she couldn't have cheated on him. Yes, maybe she worked as a prostitute but she didn't fall in love with some guy.
Ugh at least I was right. Kind of.
It would also explain why she looked... Off and tired all the time.
It would explain why she felt guilty... Why she was broken.
It would explain all the nights Katie never came home, we always assumed she was with John, but then John would call us at 4 am worried sick about Katie.
It explains why she didn't come with us to the party.
Which could be a lead in the case.
