Chapter 1!

This was a prompt from Annajadekin. Thank you so much for the prompt. I'm excited to write this story for you. I hope you like the first chapter!

On October 9th of 1981 a baby boy by the name of Spencer was born to Diana and William Reid. He seemed like a regular boy, but it didn't take long for everyone to notice how special he really was.

When he was eight years old he was transferred out of grade three to grade nine. He had an IQ of 187, an eidetic memory and was an autodidact, he could also read two thousand words a minute. He was, in every sense of the word, a genius. He graduated from high school in 1994 at the age of twelve years old. After all the bullying he had endured he couldn't wait to leave. His Father had already left by that point, leaving him with Diana who was a paranoid schizophrenic.

These were all facts that everybody at the BAU knew. Spencer was a special agent there, had been since he was twenty one years old. Five years had passed since he begun and he couldn't imagine leaving. He loved his job and he loved his team. They were liked family to him and he couldn't imagine his life without them, or the BAU.

It had been a month since Gideon had left and nine months since he had been kidnapped by Tobias Hankel. Nobody knew or at least that's what Spencer believed, but after Hankel he had developed a drug addiction to the drug that Hankel had forcibly given him. He had gotten himself clean with help from Gideon five months ago, but now that Gideon was gone he was struggling to stay clean. His struggle was about to get a lot harder.

Spencer was sitting at his desk working through paperwork when JJ came up to him.

"Hey Spence, we've got a new case," she said with a smile.

Spencer looked up, "I'll be right up."

JJ headed to the conference room as Spencer packed up his bag and followed after her.

Spencer cared about JJ a lot. For his twenty fourth birthday Gideon had gotten him tickets to a Redskins game in the VIP box. He had then insisted that Spencer take JJ, and he had. It had been one of the best days of his life, but nothing came out of it. Spencer has always wished something had though. JJ was a beautiful woman with blonde hair and bright blue eyes. She was twenty nine years old, only three years older then him. Little did Spencer know, JJ had a boyfriend that she was keeping from the team.

This didn't matter at the moment though because when there was a case Spencer dedicated himself fully. So, when the whole team was in the conference room all he cared about was the case file that had fallen into his hands.

"Alright so, a woman by the name of Ashley Michaels was murdered. She was an undercover CIA agent-" Jennifer had started, putting the woman's photo on the screen.

"Why are we taking care of this case then?" Derek asked, finding it strange how the CIA wasn't involved in this.

"I'm not sure, they sent it to us. They requested that our team specifically took this case," she answered, "the crazy thing here is, she was only sixteen years old. She was a genius, just like Spence. It's believed that she may have been targeted because of these facts. This is what the unsub did to her."

Spencer looked up at the photos and his stomach twisted, his heartbeat sped up. He understood why the CIA wanted his team to investigate this case, why they had specifically requested them. It wasn't the team that they really wanted but Spencer because he knew this case. He knew this unsub, all too well.

In one moment, Spencer felt like his whole life had been turned upside down. His past had come back to haunt him, and this time there was no running away. Not without losing everything, and everyone he loved.

"He broke into her apartment, beat her, strangled her, almost drowned her and then took a knife and slit her wrist deep enough to cause significant blood loss, but not enough to kill her yet. He then tied her up and let her bleed out until he untied her and stabbed her. The coroner couldn't figure out how many times she had been stabbed, but it was over-"

"Twenty six," came a strained voice at the end of the table.

Everybody turned to see Spencer with the case file clenched in his hands, "she was stabbed twenty six times, and she was alive and conscious for all of it."

"Reid, how can you be sure?" Hotch asked him, looking at him with concern and curiosity.

Spencer let go of the file and rubbed his own wrist, "after he beat her he drowned her and then beat her up some more before strangling her, he stabbed her before he tied her up and slit her wrist. Then he sat in front of her trying to comfort her while she was probably begging to be let go. He stayed there until she took her last breath and then called the CIA personally from an untraceable phone and said 'should've protected your young agent' then he hung up and disappeared."

Spencer fixed the order of the attack and finished the case file for them before going on, "he kills one undercover agent a year, usually it's a highly intelligent person under the age of eighteen and always on November the 3rd. They suspect that he was a former CIA who changed his identity trying to start a different life. He probably was a victim of several attacks until a severe one of November 3rd, he was also probably young like his victims. He feels like he should've been protected and that the CIA failed him. That's why he kills, to show the CIA that they don't protect their agents enough, he believes they need to pay for failing them."

"How do you know this Reid?" Hotch asked in a stern voice.

"I came across it in my studies..." Spencer lied, "he won't stop until the CIA prevents him from killing a victim. The problem is that they don't know who this guy is or who his next victim will be. He kills men, women, Caucasians, African Americans, Asians, any young CIA agent that he can get to too easily."

"So, how do we stop him?" Emily asked anxiously, it seemed like this would be one of their hardest cases yet.

"He has never failed to kill someone that he was planning on killing, the CIA never succeeded in protecting their agents," Spencer answered, "so, it's practically impossible because he only kills once a year."

"Has any victims survived JJ?" Rossi turned to JJ who hadn't taken her eyes of Spencer.

"No, not that the CIA told me," JJ answered, "they didn't give me a lot to go on though, I don't believe they gave me all the files..."

"They'll try to keep as much as they can away from us, but we need to know everything to catch this guy," Hotch stood up, "I'll call them and figure out where the rest of the files are."

'They won't give them to you,' Spencer thought silently.

His lie about how he had come across the story in his studies seemed to have convinced the team for the time being, but Spencer knew he wouldn't be able to keep his secret for long once they started digging. His team was good at what they did, but so was he. He rubbed his wrist and looked up to see JJ staring at him again.

'I can't lose her, I can't have them find out.'
