As it turned out, experience wasn't even needed. Beckett was still in the break room finishing up a cup of coffee the way Castle liked it – she'd already done her own – and she happened to look out the window toward the desks when she saw both Esposito and Ryan get up and move to stand behind Castle, looking at the computer screen. Knowing that he'd found something, she gathered both cups of coffee and headed for her desk. He'd been watching for her and gave her a triumphant and slightly relieved smile.

"What did you find?" she asked, setting his coffee on the desk before looking at the screen. The computer monitor was showing a picture of what definitely was a diamond.

"The gift," Castle told her. "Only it's not really called that, it's officially know as the Wolcox Diamond. But it's nicknamed 'The Gift' because the original owner gave it away." He looked back at the screen, but continued talking. "It was originally found in Africa, but passed hands a few times and wound up in Brazil where it was finally purchased by a consortium of museums who took turns displaying it. Until it was stolen…"

"Five years ago?"

He smiled.

"Yes. It was being going to be displayed in LA when it went missing in a daylight robbery during transport."

"Guess who was in charge of that…"

"Jeremy?"

"No. A man named Arden Rogers."

She gave him a sharp look.

"You mentioned that Jeremy was talking about someone named Roger."

"Only I must have heard it wrong."

"Not too surprising," Ryan pointed out.

"Look up Arden Rogers," Beckett told Esposito. "See what we know about him."

He nodded and headed back to his desk, while the rest of them continued looking at the screen on Beckett's computer.

"So what is that diamond worth?" Ryan asked, curiously.

"About 700million," Castle replied.

"Dollars?" Ryan's expression was astounded.

The writer nodded, looking over his shoulder at Beckett.

"Makes the Hope Diamond look like a bauble."

"And is definitely something that would require someone like your friend Jimmy to handle, huh?"

"Yeah. It also explains why a whole bunch of museums went together to buy it."

"Hey," Esposito caught their attention before they could continue the conversation. "Our man Arden Rogers was questioned at the time of the robbery and claimed to have known nothing about it. He was in charge of hiring the security company and had accompanied them during the transfer and was injured during the robbery. They cleared him of any possibility of involvement."

"Well at least he didn't die five years ago," Beckett said. "So we can track him down."

"He's here in New York," Esposito told them.

"How convenient," Ryan said.

"Can you bring him in?" Castle asked Beckett.

"For what?" she asked. "Because you heard the name Roger while being held hostage in a closet – and had a head wound that makes your memory less than dependable? Not a chance."

His expression fell, and she put her hand on his shoulder. She wasn't trying to pick on him, she just had to make him understand their lack of options just then. It didn't mean they didn't have any, though.

"Don't worry, Castle," she assured him. "We know his name, and we can watch him. Hopefully he'll lead us to the diamond – and to Jeremy."

"We still have the year books," Esposito reminded them. "We only just started looking."

Beckett nodded.

"And now that we know what the gift is, we can watch the high end fences and look for someone trying to move a very expensive diamond."

Castle sighed, deflated. He'd been so excited that he had found out what the gift was, and that there really was a Roger and he was someone that was close by and might have the rest of the answers he was missing. She was right, though, about not having a reason for bringing the guy in. Even if he didn't like that.

"So what do I do?" he asked.

"You can help look through the year books," Beckett told him. "You know what Jeremy looks like, too, so you might spot him in one." She stopped when her cell phone rang and looked at the display before answering. A slight smile touched her lips and she murmured something to the person on the other end before holding it out to Castle. "Or you can talk to your daughter."

His eyes lit up.

"Really?"

She handed it over to him and he got up so she could have her desk back. Beckett smiled at the change in his expression and was glad to see it. She watched him as he chatted with Alexis, and could almost figure out what they were discussing just by watching his face. He was cheerful when she was telling him about the trip itself, and then his whole expression clouded when she was telling him about the schools themselves. Of course, she was a trained observer of people, so that probably helped give her some insight as well.

Esposito went back to looking through the information he'd found on Rogers, while Ryan started thumbing through the year book on his desk and Beckett turned her attention back to the screen and the diamond that was displayed there. It was a very pretty stone, she had to admit, but wasn't worth killing for as far as she was concerned. It was amazing what it was worth, though, and as she continued reading about the theft, she wondered what role Jeremy and Bridget had played in it, and if Rogers had allowed himself to be injured to keep the suspicion off him during the investigation. She was still considering that when Castle returned to her desk and sat in the chair that was pretty much considered his.

"How's the trip going?" she asked, looking over.

He sighed.

"They're having a good time."

"But…"

"There's no but. She's smart enough that the colleges are rolling out the red carpet for her and showing her a very good time. Making their pitches and trying to get her interested…"

"That's good."

Castle scowled.

"I suppose."

"How much longer will they be gone?"

"She asked if I minded if they stayed on the west coast a little longer – now she wants to check out Montana."

"Montana?"

He made a face and nodded.

"Something about veterinarian research that is supposedly ground-breaking…"

"Does she want to be a vet?"

"She mentioned it a few times when she was five," he muttered.

"Well, some kids know what they want even that young."

"Yeah, well…" he reached for the year book that Esposito had left for him to look at and opened it. "She wanted to be Barney, too."

Beckett grinned.
