“Regan?” Lucas said. “What are you thinking? It sounds like this letter writer knows more than what’s on the page.”

“She does,” Regan said. “And so does Taylor.” She told Lucas how her conversation had gone. “I want to go back and confront her, but I don’t know if that’s the best approach, at least not until we have more information. I’m hoping after our conversation that she’ll listen to the podcast—if she hasn’t already—and call in. Or be more honest when I talk to her again.”

“You’ll be there on Friday again, right?” Lucas said.

“Yes, I said I would.” She’d become as invested in solving Candace’s murder as Lucas.

“Because,” Lucas continued, “if Taylor does call in, I have no idea how to get her to talk.”

“If she calls in it’s because she wants to talk,” Regan said. “And that means we need to ask open-ended questions, get her to tell us more than she plans to. She knows something she didn’t want to tell me. It could be innocuous—or it could be answers we need.”

“I looked up the other sorority sisters Annie mentioned in your conversation,” Lucas said. He flipped through a notebook on his desk. “Alexa Castillo is a year older than Annie, and I couldn’t find anything on her. Castillo is a pretty common name, but I can’t find an Alexa or Alexandra or Alexis who graduated from NAU in the last four years on social media, but I kept it narrowed to Arizona. Maybe I should expand it. The sororities all have online newsletters and webpages, but the newsletters are archived as PDFs so I have to click on each one before I can search for a name. But I think it’s worth doing because they often post updates on graduates. I’ll start in on it tonight and look for Alexa Castillo and Kimberly Foster.”

“Good,” Regan said.

“I called Chrissy to ask about Candace’s journal, but she didn’t answer. She’s pretty good about calling me back. I’ll text you if she has any information.”

“On Friday, for your next podcast episode, I think you should push the report from the witness who saw Candace leaving the library on Tuesday morning. You can even replay a clip of that, right? To remind people? That might generate other viable calls. And whoever wrote this letter—they say they don’t want to call, but there’s no reason you can’t read the letter on air. It could spur someone else to call.”

“That’s a great idea,” Lucas said, making a note.

“I’ll see what I can find out from Rachel Wagner, the advisor. Maybe convince her to be interviewed, since she knew Candace.”

“That would be great.”

“Don’t hold your breath, but it’s worth pursuing.” She glanced at her watch.

“You have to go?”
