Don gave Colby a nod of thanks and the heard a disturbance coming from outside the office.

"I demand that you tell me what is going on with Charlie NOW!" Amita screamed at the poor rookie that was put on guard duty at the crime scene. Don heard who it was and muttered, "Lord help me" as he walked over to allow Amita in to the office and most likely Larry is not far behind Amita.

Just how Don imagined, Larry was standing behind a very angry Amita. Don motioned for both of them to be allowed into the office. Amita brushed past the guard and went to Don and said, "Don what in the world is going on? Where is Charlie? What happened?"

Don brought over two other chairs and sat Amita and Larry down. He put his hands on Amita's shoulder and said, "Sweetie, Charlie was helping us track down a serial rapist who was targeting young adult men. He phoned me and told me he had a break through with his analysis about where he thought the rapist would strike again. I got here and there was a puddle of blood on Charlie's desk and a bloody handprint over Calsci on the map that Charlie was working on. Past that we have no idea yet where he is or how he is. I can promise you though none of us will rest until we get him back."

Amita and Larry sat looking at Don with shocked expressions on their faces and Amita had tears streaming down her face. Don reached over and pulled Amita into a hug and whispered into her ear, "I promise I will bring our Charlie back to us."

Amita wiped her eyes on the back of her hand and steeled herself. She was a strong woman she wasn't going to allow herself to sit in the corner and cry. She looked at Larry and then at Don and said, "Give us his laptop and his map and we will work on the calculations he was making maybe between the two of us we will be able to figure out Charlie's algorithms."

Don got up and patted her on the shoulder, "I will go and get them for you, I think that will be great. You can work on them in the garage at the house. I will go with you. I need to tell Dad what is going on. Wait here, I am going to make sure the team is going on the investigation and we can go."

Don got up and walked over to his team huddled in a circle across the office from Amita and Larry. Don asked, "Well, what have we got and where are we going from here?" Colby and David said, "We are going to go to campus security and get the footage from the cameras around Charlie's office and we are going to talk to the teachers and students around here to see if anyone saw anything."

Don answered, "Good start, let me know if you come up with anything. I am going to be at the house filling in Dad on what happened. Keep me posted and get the others to help you chase down any leads. We can't leave any tip or lead uninvestigated."

Don went to grab the map and the laptop and put them in Charlie's backpack and motioned for Amita and Larry to follow him. They all piled up into Don's SUV and headed home.

All the way home Amita and Larry were silently looking out the window and Don was in the front seat praying that Alan would not have a heart attack when he heard the news about his youngest. They pulled into the house about 10 minutes later and Don walked into the front door and was greeted by his Dad.

Alan cheerfully said, "Hey son, your early for dinner, Charlie isn't home yet." Alan looked at his son's face and a wave of panic washed over him. "Oh God Don, what happened? Are you okay? Is it Charlie?"

Don swallowed hard and asked his Dad to sit down at the table with him. "Listen Dad, you know how there has been a serial rapist loose in L.A? Well we got brought in on the case this morning and Charlie said that he could work on his math stuff and try and find where the next victim would be from. He called me tonight and told me that he had something. When I got to his office he was missing and there was a bloody hand print over Calsci on the map where he was tracking attacks."

All the color fell out of Alan's face, "That sick bastard has my Charlie?"

Don closed his eyes to choke back the tears and he just nodded at his father's question.

Alan got us from his place at the table and began to pace the floor, "Oh God! Oh God! I knew this was going to happen. Charlie is fragile. He is a mathematician he belongs in a classroom at a chalkboard. Instead he is out playing cops and robbers with his big brother. Now he is gone. My boy is gone. Don you have got to find him. He isn't strong enough to handle this you know him. Please find him Don and when you do forbid him from helping you ever again please Don. Promise me you will forbid him from helping him please."

Don got up and pulled his Dad into an embrace. He hugged him tight and both men cried on each other's shoulders. Don in a chocked up and broken voice said, "Dad, I promise I will not rest until Charlie's home safe and sound. We will bring him home."

Don sat his father down in his recliner and told him, "You sit here and rest okay pops. Amita and Larry are out in the garage working on the math that Charlie used to see if we could find a lead. I am going to go back to the office after I see them but they will be here if you need anything and I will have my phone okay."

Alan shook his head at Don and just sat starring out the front window of the house. Don sighed and patted his Dad's shoulder, "I love you pops".

Before he could walk away Alan grabbed Don's hand and said, " Be careful, please, and bring your brother home." Don smiled and nodded at his Dad and left.

When he walked into the garage Amita and Larry were hard at work on Charlie's algorithms. Don knocked on the doorframe and asked, "How is it going?"

Larry looked up from his work and answered, "Charles is truly a genius and his work is sometimes a little tough to decipher but between the two of us we are making progress. We will call you when we have anything."

Don smiled at Larry and said, "Okay, I will be waiting, if anyone can do this you two can. I am going to have a uniform sent out to stand guard at the main house and the garage okay. Just in case. We are dealing with a maniac here and I don't want to take anymore chances till he is captured."

Don went out of the garage leaving Amita and Larry buried in their work to decipher the genius of Charlie Eppes.

Don got back into his car to head to the FBI. As he drove his mind wandered to his baby brother. Don thought, "What horrors is he having to go through?"

Across town in an abandon home on at the beach Charlie woke up in the worst pain he had ever felt. His entire body was hurting. He tried to sit up when the world began to spin and he laid his head back down.

Charlie heard some movement on the other side of the room. He was still blindfolded but he was trying to use his other senses to try and get an idea of where he was being held. He heard the sound of footsteps getting closer to him. Then his blindfold was taken off his face.

The kidnapper said, "Well good Morning Dr. Eppes, you have been sleeping a while. It is time to wake up. I need your help to mess with the FBI a little. They think they are going to find me well they are wrong. With out their little pet genius to help them they wont find you till I want them to find you. Or should I say your body. First I think I am going to let you spend a few minutes with my friend Sergei here. When you are done with him I think you will be ready to send a message to your brother."

The kidnapper left the room as he left he laughed at the sounds of Charlie getting hit and kicked and the weak pathetic cries of Charlie.

An hour later the kidnapper returned to find Charlie in a ball in the corner of the room. He was bleeding more than he all ready was and his face was nearly unrecognizable from the swelling and bruising.

The kidnapper pulled the corner of his chin and smiled, "Yes, Sergei did a great job. I think you are ready for me to snap a picture for your brother. Smile pretty, this is the last picture that he will have of you alive."

When Don got back to the FBI he checked in with his team and then sat down at his desk to check his email. The first email he had been labeled; "you will never catch me in time". There was an attachment, he clicked it and screamed out NO! When he saw the picture. He got up and started to pace in his cube rubbing his face and muttering, "Oh God no not Charlie, Oh God no."

His team rushed over to his cube and they all froze when they saw the picture of Charlie on Don's computer screen. Megan started to tear up and she reached over to embrace Don. Normally he would never allow it but today he did. They all couldn't stop looking at the figure in the picture, it was obviously Charlie but he was beaten so badly. All Colby and David could think about was getting their hands on the man that would do this to Charlie.
