A/N: Ringer = one of my new favorite shows. Veronica Mars = one of my other favorite shows. And guess what? They .perfectly together. So I decided to write a crossover for them. And it's FUN. Lots. Of. Fun. Additionally, I don't claim to know the geography of New York City. And also, Veronica gets clearance from the FBI to work on the case. So yay.

WEIRD THINGY WITH THE WRITING: Okay, so I call Bridget "Siobhan" in the first chapter. It's because I'm telling it from Veronica's perspective, but in third person. Obviously, she doesn't know that it's Bridget pretending to be Siobhan, and therefore she thinks of her as Siobhan Martin.

SPOILERS: Spoilers up through "Maybe We Can Get a Dog Instead" from Ringer and all the way through Veronica Mars. This takes place...mhh...I'm thinking right before Juliet gets transferred out of Mr. Carpenter's English class. Like, there was a day after when she had the conversation with him after class and when she got switched.

And now, without further ado...

Solved: Chapter One

"Dad!" Veronica exclaimed, walking into Mars Investigations. "I'm here! Surprise!"

Keith Mars stepped out of his office, followed by a guy in a suit. Keith gave her a brief hug, then said, "Veronica, would you be interested in working on a case?"

"Depends on how interesting it is. I did just get off work..."

"Oh, honey, you'll like this one. Plus you'll get a free trip to New York."

"Tell me of this case."

"I'll tell you on the way to the airport. We're going to miss our flight."

"You were so sure I'd say yes?" Veronica asked, a smile twitching at the corners of her mouth.

"You always say yes."

The suit's name was Agent Machado.

"So her twin is lying for her?" Veronica asked.

"Definitely. Well, allegedly. But definitely." Machado replied.

"That doesn't make sense. They haven't seen each other in six years, but she's willing to lie to the police to help her keep from testifying against a repeat murderer? No. There's a piece missing."

"Well, they're twins. It's different, I guess."

"Have you considered the possibility of Siobhan killing her sister?"

"Yes, but Siobhan's not a psychopath. Why would she kill her sister?"

"Again, she hasn't seen Bridget in six years. She's probably closer to Gemma than she is to her. I'd kill the person who murdered my best friend."

I'd have killed Aaron Echolls.

"We'll look into it," Agent Machado said, making a note in his iPhone, "but I doubt it. Once you meet Siobhan, you'll see."

"Maybe. And the sponsor just showed up?"

"Malcolm Ward. Yes."

"He'll be the next target if Siobhan killed Bridget. I'd get him in protective custody. He should be there anyway, already, with the fact that he was just held in a strip club and tortured."

Agent Machado pulled his iPhone back out and dialed a number. "Sofie. Get Malcolm Ward in protective custody. Now. And I want Siobhan Martin in the precinct ready for questioning by the time I get there."

Veronica leaned back in her seat, reclining it. She hadn't had a good night's sleep in weeks...

"Veronica, honey. We're landing." Keith shook her awake as the plane touched down at JFK.

"Ugh. How long was I out?" Veronica asked, then smiled. "It's nice to be able to ask that question about sleeping instead of unconsciousness."

Keith smiled, too. "About five hours. You woke up over Denver long enough to eat your peanuts."

Veronica had a vague recollection of this.

"So we're going straight to the precinct?"

"Yeah. We should be there soon, after we get our bags."

"Agent Mars. So great to have you there." Another federal agent, Anna Howard, whom Veronica had worked with on one other occasion, shook her hand.

"Has anyone talked to Siobhan yet today?" Veronica asked, moving toward the door.

"Nope. She's fresh meat for you."

"Thanks, Anna." Veronica opened the door and stepped inside, taking the chair across from Siobhan.

"Haven't you asked me enough questions?" Siobhan asked.

"I haven't asked you any yet." Veronica held out her hand. "Veronica Mars. I'm with the FBI."

Siobhan shook her hand.

"So you have a daughter right?" Veronica glanced at the file. "A stepdaughter. Named Juliet?" Siobhan nodded. "I'd like to talk to her later. Since she's a minor, I'd like you to sign this so that I can speak to her."

"About what?"

"Oh, you know. Stuff."

Siobhan hesitated, so Veronica plunged back in. "Mrs. Martin, I know your husband left his last wife for you. I'm sure the prior Mrs. Martin would be happy to sign this form for me. And I'll fly it all the way down to Miami if I have to in order to get this form signed."

Siobhan grabbed the paper and signed it with a loose but elegant cursive.

"Thank you." Veronica took the form and tucked it into her bag before her interviewee could change her mind. "Now, would you mind telling me if you were the one who called in the anonymous tip about Gemma's body?"

"It wasn't me," Siobhan said.

She was a good liar. But Veronica was better.

As it were, Veronica might not have decided that it was a lie if it weren't for Siobhan's mouth. Her lips curled inward a tiny bit when she said this, as if she were trying to keep them from letting the truth escape.

"Okay. I'm not going to press you on it, since it's an anonymous tip line, but I will be checking security camera footage from around the payphone the call was made from."

"Why? I haven't done anything wrong."

"I'm not saying you have, Mrs. Martin. I'm really just at a loss, and I want to explore every possibility to find your sister safely. And, trust me, I will find her." Veronica locked eyes with Siobhan.

Siobhan met her gaze steadily. "Trust me. All I want is to know that my sister is safe."

"Well, that's really it. You're free to leave now. And I'll be speaking to Juliet at some point today."

Veronica stood and guided Siobhan out.
