I DO NOT OWN ANY OF THE CHARACTERS THEY ALL GO TO UNCLE RICK

Percy Jackson sprinted into the room followed by his best friend/co-worker, Jason Grace. They had been called to Pine Tree Drive, apartment number 9, with a code blue. Code blue was when someone called in hearing maybe gunshots, screaming, anything that had to do with one thing.

Murder.

Percy was driving to work at 6AM in the morning. He was an FBI agent. He solved thieving and cases all around HalfBlood City, and sometimes out of town. He was almost to his office when he got a call that was immediately transferred to his car.

"Siri, answer it please," he said aloud. Perks of being an FBI agent; you get a program installed where all you have to do is say the word and your car will do it for you.

"Yes, Agent Jackson," she said. "Answering call from: Jason Grace."

"Hey, Grace, what's up-" Percy started, but Jason's voice answered fast and panicking.

"Jackson, we need you to get to Pine Tree Drive apartment number 9 this instant, I'm just leaving the office right now. I got a call about a code blue. Some lady next door called and said she heard screaming and gunshots. Where are you?" Jason said quickly. Percy had just pulled into a parking spot and he saw Jason's bright blue car next to him.

"Roll down your window, Grace," he said. They rolled down their windows Jason rolled his eyes.

"Just come get in my car, Jackson. It'll be faster," Jason said. Percy hung up the phone, quickly, adjusted his weapon belt, and got into Jason's car.

"Lets go."

"I'll cover the living room, kitchen, and bedroom, you get the rest," Percy said, and they split up, holding their guns out in front of them and looking around. Percy headed into the living room first. Everything was dark, no lights.

"Hey, I recognize this place. I must of been really little or something but..." Jason calls out trailing off. Percy ignored him and moved onto the kitchen. He scanned everything and looked through drawers. One of the knives was missing from a holder, and there was blood on the floor that Percy hadn't noticed before.

"Grace, don't move, just look around," Percy whispered into his walkie-talkie. Jason didn't respond, and Percy took that as a yes.

Percy slowly crept forward and heard a crash near Jason and a gunshot go off.

"Jason?" Percy called out. No response.

"I need backup. Backup now," Percy called into his walkie-talkie, calling the station. Percy crept back through the living room and pointed his gun wherever he looked.

"Jason?" He called out again. No response. Then Percy heard a cruel laughter echoing around him. He spun in a full circle but there was no one there.

"Ah, Agent Jackson. Nice to see you again."

Again? When had he heard this voice? He had never heard it, he was sure.

"Come out with your hands up," Percy demanded. The voice laughed again. Now it was behind him. He whipped around but no one was there. Every time the voice stopped talking it just kept laughing.

"Poor Agent Jackson," the voice sneered his name. "You know, I really like you once. That was before...well you know," the voice said, and then it started laughing again.

"Not that I can see you, but I suspect your looking around for me. Well, check the kitchen, oh brave Agent," the voice said. Percy has questions flooding his mind but he headed to the kitchen slowly. He heard sirens outside. When he entered the kitchen he saw something that hadn't been there before. On the counter was a bloody knife, next to a small box. It vibrated with laughter and the voice spoke from it.

"Have you found me yet, Jackson? I suppose you won't, because by now, I'll have been long gone," the box said. Percy roared and took the box smashing it on the ground, breaking it so the laughter stopped. A stupid trick. It was a trick. The sirens were right outside, and Percy saw the open window from the kitchen. Wind was blowing through it, and blood dotted the curtains and the window sill. Percy yelled in frustration,  that it was cut off by a gasp. He saw blood trailing into the bedroom he hadn't checked.

He kept his gun up and his taser handy, and he heard police rushing up the stairs. Thank god. He pushed open the door and a horrific sight met his eyes. On the bed, was a girl with short black hair with some colored highlights in it, and a black shirt with some rock band on it. Her jeans were black with a black belt. But the worst of it was the way she was positioned. She looked like she was trying to crawl onto the bed, and she flipped herself over halfway. Her shirt and right leg was soaked with blood and stab wounds. Her hair was matted with blood and she had scraped everywhere. Suddenly the police burst into the room and Percy called them over.

The worst part was that he knew this girl. No wonder it had looked familiar to Jason. He had thought this girl had died shortly after he was born, and never been here. The girl had asked Percy to keep her location a secret, as Jason's life would be screwed up if she had been in it, or so she claimed.

This girl was Jason's sister.
