The story begins with a red-haired girl doing homework at a library. It is dark outside and there is hardly anyone there. She rubs the sleep out of her eyes and glances at the clock across the room. Groaning, she begins to garner her many pieces of paper that are strewn about the table and places them all neatly into a binder, zips up her green backpack, and quickly strides out the door.

Once outside, she passes a sign that reads, "Haron University Parking." A few cars zoom past across the street, and crickets are heard faintly in the background. She makes her way to a light blue truck and fumbles through her purse, scrambling to find her keys; mumbling as she does so angrily.

All of the sudden a hand flies out from behind and covers her mouth with a white cloth. Terrified, she releases her purse and attempts to escape. After a couple seconds of struggling, her grip slackens and she slumps into the grip of a person obscured in the shadows, who then places his arms around her waist and drags her to a car three parking spaces to the right and tosses her into the back seat. Once the person is inside, he starts up the car and speeds off to join traffic outside the college parking lot.

The team is in the conference room, with JJ briefing them on a new case. Behind her on the screen are pictures of three girls and a map is viewed faintly in the background.

"These are the crime scene photos of two college girls, who appear to have been killed by the same unsub in Williamsport, Pennsylvania." She points to the first two pictures displayed on the screen. "Their names are Heather Garton and Sharon Karn. Police believe the next victim to be Ashley Warren," (she pointed to the last picture of a young woman with red hair), "because she was recently abducted in the college parking lot last night."

"Heather and Sharon were found in the park near the college with their shirts ripped off and a large letter F branded onto their chest—" (the focus turns to a picture of one of the girls' stomach. There is a large red and bleeding welt in the shape of an F that covers her whole chest. It changes focus on the rest of her body as JJ finishes) "-as well as the words 'Liar' and 'Cheater' on their arms. They were raped and then murdered by lethal injection."

"However, that's not the worst thing about it." JJ sighed and bit her lip, then changed the images on the screen and said slowly, "Each girl's brain was surgically removed." She hated this part of the job, having to view horrific and gory pictures of victims, and the knowledge of how disturbed the serial killers were. Lately they had seemed to get gorier and gorier.

Gideon rubbed his forehead, as if it hurt to process the information. Hotch started blinking as if his eyes were dry and pretended to be distracted by something to his right. Reid just stared at the pictures of the girls on the screen, his mouth wide open and looked to be sick. Prentiss shook her head as if to clear it and slowly put one hand to her forehead as if she had a headache. Morgan closed his eyes painfully, opened them, and glanced up sadly.

"So the unsub brands the girls, rapes them, kills them, and then takes out their brain as a consolation prize?" Morgan wonders aloud incredulously. By now he was seriously considering putting this new guy on the "Top Most Disturbing Unsub" list.

"Or, he could believe that the girls deserved to be punished and he was doing God's will," Reid began darkly, remembering his past experiences. "By branding them with the words 'Liar' and 'Cheater' and the letter 'F' he is proclaiming why he did it. The only question is, what does 'F' mean?"

"It could be his signature, letting people know that it was him," Gideon suggested softly.

"What college were the girls found near?" Prentiss inquired.

"Haron University," JJ answered.

Prentiss's eyes widened, but she didn't say anything further. It took her a second to get her expression back to normal as quickly as possible, but it warranted a furtive glance from Gideon across the room.

"Is there anything these girls could have done to provoke someone to call them a liar and cheater?" Hotch asked.

"No. All three girls were involved in the school, got good grades, and have absolutely no criminal records. From the information in their files, they are low profile," JJ announced as she held a large file in her hand.

The team was silent for a moment then Gideon ordered, "The plane will leave in half an hour for Williamsport. We'll continue debriefing there." At that everyone except Prentiss quickly left the room. When Gideon came to the door, he turned around to face Prentiss, who was slowly getting out of her chair.

"Who do you know in Williamsport?" he asked concernedly. He knew she was looking out for somebody the instant she asked what university it was, and the expression she let slip once she heard.

Prentiss looked a little started, but then said fearfully, still attempting to keep her outward emotions under control, "My younger sister goes to Haron University."
