Crossing Lines

The Mexican sun beat down over head and the wind seemed to do nothing other than blow the heat back and forth. The blond-haired man cursed as he scraped his knuckles against the metal of the old Ford truck's engine and the wrench he was using fell through the block and onto the ground beneath the truck. He dropped to his knees and looked under the vehicle at the tool mockingly out of his reach. Sighing heavily he flattened onto his back and slid beneath the truck, snatching up the tool and laying still for a moment enjoying the shade. He listened to the sounds of cars coming and going, of footsteps fast and slow and of conversation both animated and subdued as he let himself relax for just a moment. He started to slide out from under the truck, when he heard footstep approach cautiously and a shadow blocked the sun.

He blinked up at a blond-haired woman and strained his blue eyes to focus on her as she looked down at him. He wiped the sweat from his brow and pulled himself to his feet quickly.

"Brian O'Conner." She looked him over once as if assuring herself.

"Naw. You got the wrong guy." He shook his head and turned away from her.

"No I don't." She insisted, glancing down to a file in her head then up at him.

Brian weighed his options, quickly assessing that she was armed and she was law enforcement. "Yeah, you do. I'm not him." He waved his hand dismissing her and started walking towards the garage.

"I know you are him. I know about the drug cartel and I know you used to be a fed before you fled down here." She grabbed his arm and shook her head. "I'm not US agent. I'm Mexican drug enforcement. I just need to speak to you for a moment."

"I'm not cop anymore, I can't help you. And as far as I'm concerned the Mexican drug enforcement unit is a joke." He shrugged off her hand and started away from her again.

"It is." She dropped her head for a moment. "And my unit did more harm to you than you know." She held up the file in her hand and cleared her throat. "We were investigating the same cartel. We had a man on the inside too."

Brian stopped in his tracks and turned around to look at the tanned woman. His eyes narrowed and he took a step back towards her, "I had more than one operative in that investigation and I lost them all. One of them was a friend. And you don't look like a Mexican cop. I think you're full of shit."

"My mother moved to Mexico when I was young. I just never left, but I hate this country." She opened her file and looked down at the contents. "Our man went native."

Native. There was a word burned into Brian O'Conner's brain. That was the accusation he heard over and over after his investigation into the Toretto family. Of course that's exactly what happened, he fell in love with Mia and the high-adrenalin life-style. "What the hell does that have to do with me?"

"I'm Mexican drug enforcement, but I don't work for the government. I work for a privatized firm, rich men that supposedly what the drugs out of Mexico, but it's really about getting rid of the competition." She looked over her shoulder suspiciously. "Can we talk inside?"

Brian folded his arms over his chest. "No. You wanna talk, talk fast and talk right here."

"Fine." She pulled her hair back into a ponytail. "The agency I work for is extremely competitive. Arresting officers get to keep half of whatever they seize in cash assets. But they won't be embarrassed; if an operation fails they make the inside-man disappear."

"Saves on retirement I suppose."

"No. The organization really makes them disappear. Hides them in safe-houses until they're found by someone and rescued or they are put back into other operation. I've been looking for my sister. They made her disappear."

Brian looked towards the garage. "And this has what to do with me?"

"Nothing." She sighed. "I was handler for a man that was inside the cartel and he got killed by someone in the cartel, but oddly not for him being a cop."

"It was Phoenix. He was second in charge, always killed the drivers, didn't matter who they were." Brian cut her off abruptly. "You aren't telling me anything I don't already know."

"Phoenix was our man."

"He went fucking more than native then. He was…."

"I know." She handed the file over to Brian. "Handlers stay with their man until they die, but Phoenix's handler stopped reporting on him in early March of this year. I know when Phoenix died and it was almost April."

"So what?" Brian opened the file and starred at a photo of Phoenix and a smaller Mexican man.

She cleared her throat. "Beto, Phoenix's handler stopped reporting after he sent out an emergency signal, it came from L.A. I was on the team that cleaned up the crash site; we were trying to destroy any evidence that might connect that murder to us or to Phoenix."

Brian grabbed the woman's arms and slammed her back against the truck. "Was it a woman? Was it a woman's murder you tried covering up? You answer me."

"There was a dead woman and burning car. That's all I saw when I was there. It's all in the file." She insisted. "Beto stopped reporting for two weeks, then he reported once from a safe house in Mexico City and then in May he reported from a safe house in Veracruz. But that's what I am trying to tell you."

"What the hell does it matter about this guy?" Brian let her go and watched her rub her upper arms.

"The safe house must have new, because the land-line still worked. There was one out-going call that connected: it was a house in Tecolutla, lasted about 5 minutes, and that number…" She took a breath, "Has been calling the Toretto's home, every day since that that phone call. All the info is in that file. I don't know what that person wants with your friends, but I figured you might want to pass along the information." She pushed herself away from the truck and started back towards her car. "For what's its worth I'm sorry about you friend."

Brian looked down at the file as the car peeled out of the parking lot. There were pictures of this Beto guy, Phoenix, the woman who handed him the file, two other men he didn't recognize, one of Letty and one of another young woman. There were autopsy reports, case records, chatter transcripts, and two telephone numbers: one was a Mexican number and the other was the Toretto's home number, circled in red.

.:.

Mia Toretto pulled back her long ponytail and smiled at the little boy, who arm she just bandaged. "Just keep it clean and change the wrap tomorrow morning." She explained to the mother in Spanish.

The woman thanked her and handed her a few apples, apologizing that it all she had for payment.

Mia smiled again and told her not to worry, that she was glad to help and sent the pair on their way. She flipped her open sign to closed and turned off the clinics lights. She paced her way to the small apartment behind the clinic and jumped to see Brian sitting at the kitchen table.

"Jesus. Are you trying to scare me to death?" She complained, setting apples on the counter.

Brian just shook his head and didn't look up from the file he was studying.

"What are you looking at?" She questioned trying to look over his shoulder.

He closed the file and put his hands over it. "Nothing."

"Doesn't look like nothing to me."

"Don't worry about it. It's not important, I don't think."

"Is it or isn't?" Her eyes narrowed and she reached for the folder.

Brian pressed his hand down folder to keep her from getting it. "Do you know anyone from Tecolutla?"

"No. I don't think so. Why?"

"Could Dom?"

"I don't know. Damn-it Brian. If you want this to work between us, then you have to be straight with me all the time, not just when you feel like it." Mia folded her arms over chest and glared him. "What is this all about?"

"This woman came by the garage today and gave me this file. She told me that Phoenix was an operative of a Mexican corporation trying to stop the cartel activity and that he went native. His handlers stopped reporting the night Letty was killed and he reported recently from an area in Veracruz."

"What does that have to do with us?"

Brain sighed and opened the file to the phone numbers and pointed to them. "Since he reported in, that Mexican number has called your home number every day."

"I should call the number." Mia reached for the phone, but Brian blocked her.

"No you shouldn't. You have no idea who it is."

"Brian, if I call the number, I'll know who it is."

"And then they find out where you are."

"It's a phone call. I'm not going to invite them down for a beer. I'm just gonna call the number and hear how they answer."

"Absolutely not. This might be about your brother and I'm not letting you get in anymore trouble over him."

"God, this is so not your fucking decision."

"As long as I have this folder it is."

"Give it to me." Mia grabbed for the folder, but Brian held it away from her. "Fuck; Brian give it to me." She stretched across the table trying to get again but he moved again.

"Can I come into this kitchen or am I gonna be seeing something I don't want to." Dom's rumble caused the pair to look in his direction as he came in through the back door.

"File." Mia said simply and Dom snatched it from Brian and handed it to his sister. "Thank you." She smiled superiorly and opened the file to the back.

"Sure. What is it?"

Brian tried to grab the file again. "She's calling some number and she doesn't know who it is."

Dom pulled a cell out of his pocket and handed it to Mia. "Burn phone, don't be dumb. I don't want a bounty hunter coming down on us." He looked at Brian, "Where'd the file come from?"

"Some woman that knew Phoenix said he used to work for her company." He called out to Mia semi-desperately, "Mia, I don't think this is good idea."

"Shhh. It's ringing."

Dom narrowed his eyes at the new information. "Speaker-phone."

"You guys aren't that quiet."Mia rolled her eyes.

"Now." Dom growled at her.

"Okay." Mia hit the button as a voice answered.

"Hello Shayne O'Conner's Visions, How can a help you?" The chipper woman repeated the phrase in Spanish perfectly and was quiet for a moment. "Um… Hello?"

"Hi." Mia stuttered slightly flustered. "I was wondering what your hours were?" She shrugged at the guys when they looked confused.

"Oh yes. I have my gallery open from 10am to 6pm on the weekdays, but I normally take a break at 1pm to have lunch with my son and I'm open from 1pm to 8pm on Saturdays. I can open by appointment on Sundays though. Were you looking for an existing piece or were looking to commission a something?"

"Um, I just wanted to travel down and see your art in person. The website I was looking doesn't do your work justice."

"I recently updated my site, but some of the photo quality isn't the best. Was there a piece in particular you were interested in, I could send you a high-res photo by mail, if it would be more convenient."

Mia scratched her temple and Brian rolled his eyes. "Um, I was planning a trip anyway."

"I see. Have we spoken before? I think I recognize your voice."

Dom grabbed the phone and clicked it off. "What was that all about that? I want some fucking answers."

"The woman I spoke to today said that, that number has been calling your family home every day for 3 months straight. Other than that…Mia what are you doing?"

Brian and Dom both looked at Mia as she hooked the burn phone into her laptop. "I'm looking at this website to see if it's really there."

"What woman? When did you meet her?" Dom pulled a beer out of the fridge.

"She just showed up at the garage." Brain ran his fingers through his hair.

"Guys." Mia stared at the computer screen.

"You don't find that odd, or dangerous. Fuck, probably led a bounty hunter right to the door."

"Guys." Mia insisted.

"I can spot a tail Dom I was cop for almost 10 years."

"Guys!" Mia turned the laptop around and faced towards the arguing men. "Look."

The title of the page read "Shayne O'Conner's Waiting for My Heart Series published 2004/2005," but the images on the screen silenced them instantly. The paintings on a screen were of a dark-haired woman staring into space, sitting on a bench, lying on a stone wall, but the last one was close-up of the woman wearing a silver cross.

Dom touched the screen almost reverently, "Letty."
