Chapter 7: Rolling on a Hunch

"Where's she going in such a hurry?" Danny asked as Steve followed Violet out of his office and the young woman left the Five-O bullpen all together. "What did you say to her?" Danny asked in a scolding tone that made even Toast cower away.

"I smooth talked her into going back to school. Grab your tablet. You can continue your investigation while we stake out Goldstein."

"What's the point in staking him out?"

"I have a hunch."

"Oh, I love it when you have hunches - means I'm getting shot at or some such nonsense."

"Hey, I said you could bring your tablet. You can keep working on whatever it is that you're busy with and if you find something worth pursuing then we'll go after it, but for now I'm curious to see how Goldstein reacts to Violet."

"I thought you sent Kono into class." Danny said with a questioning look on his face and annoyance on his tone and Steve barely paid any attention to Danny - he was too busy texting and walking toward the door.

"I did, but my plan was always to use Violet as bait - and by always I mean from the moment the Governor said I had to work with her. By her own admission, she's the perfect victim and if this man is a true psychopath, he wont be able to pass up Violet which might give us the time to find Lydia."

"And put an officer in danger?"

"She's got Kono as back up. Besides, I don't think he'll act on his impulses until he can separate Violet from the rest of the public." Steve explained and waved Danny over from the double glass doors. "Are you coming or not?"

"If he is our guy, and he's already met Violet, wouldn't he have acted sooner than this?" Danny asked skeptically.

Steve shrugged, "if he's not our guy than you're still looking and so is Toast, Catherine and Chin. But if he is our guy and we wait too long to bring the heat, we'll absolutely be finding Lydia's body," Steve reasoned out the scenarios. "Besides, I believe, you believe, that Goldstein is our guy."

"I have a feeling, but I don't have the evidence to back it up and rolling on a hunch is sloppy police work." Danny stated.

"But two of us have a feeling, that's got to be enough."

"Sure, and if you jumped off a bridge, I most certainly wouldn't follow you." Danny stated in exasperations. "We, all of us, may be jumping to conclusions. We don't have any evidence, just a hunch."

"Yes you would, and you have, because you're a good partner and you trust me. So come on!"

Danny rolled his eyes, grabbed his tablet and followed Steve out to the car.

Silently, as he stood alone at the smart table, Toast cracked an imaginary whip and carried on with his investigation.

Outside the lecture hall Kono mingled with the other students. Not surprisingly, the whole of the student population for the specialty class was women - all except two men who were clearly a couple and who wore more jewelry than any of the ladies in attendance.

Out of the corner of her eyes, Kono saw Violet walk in. She had a note book in her hands and was texting frantically - her badge and her weapon were still on her hip and she seemed to not notice Kono at all.

Kono's phone pinged.

"Violet is there to put the heat on Goldstein to see if we can flush him out. Danny and I are on our way to stake-out the professor. Carry on with your cover." The text message was from Steve and moments later she received a text - much along the same lines - from Violet.

The two women made brief eye contact and then carried on in their separate circles as they waited for the professor to show himself.

"Detective Austen," Goldstein stated cheerfully as he rounded the corner and came face to face with the detective - the rest of the students were already in the lecture hall, Kono included. "I wasn't expecting to see you."

"Why would you?" Violet half laughed. "No, I'm here doing a little research."

"Detectives do research outside of lecture halls?" Goldstein asked almost mockingly.

"No," Violet smiled and pocketed her phone, "I'm here for you and your expertise."

"Me?" He asked suspiciously, and then recovered. "I'm just a historian, what can I do for you this time?"

"I'd like to know more about antique jewelry." Violet stated with a bright and playful smile.

"It would be my pleasure to explain anything on the subject to you, but alas, I have a class to teach. Perhaps you would like to schedule a private meeting."

"I'm here to audit the class." Violet answered. "I wouldn't want to take up any more of your time. Just treat me as one of your students and I'm sure I'll learn all there is to know."

A smile spread across Doctor Goldstein's face. "May I enquire as to what has spurred on this sudden interest in to the ancient arts?" he asked smoothly as he stepped aside and motioned for Violet to enter the lecture hall.

"I have a case where the killer takes jewelry from his victims. I want to know what is so special about the types of jewelry he's chasing." Violet answered and quickly stepped toward the front row of chairs and readied herself to take notes.

From halfway up the risers in the theatre styles lecture hall, Kono had watched the exchange between professor and detective. There was almost something like flirtation in the way Goldstein spoke to Violet. Kono didn't like it one bit. The hair on the back of her neck stood on end as she watched more carefully.

In the beginning of the conversation there had been something like shock. Goldstein had recovered from it quickly but it returned again as Violet took a seat at the front of the class. This time it took longer for the affects to wear off and for a moment, as the professor shuffled through his notes and mistyped his password into the schools computer system to bring up his lesson slides, Kono realized that maybe, just maybe, Steve and Danny were onto something.

As quickly as the discomfort had come over the professor, he pushed it aside and began his lesson into ancient gemstones and how to tell their cuts and flaws.

Kono shot off a quick text to her silently stewing boss and then hunkered down for a two hour lecture.

"We got a reaction," Steve stated proudly as his phone chimed and he checked his incoming messages.

"A reaction could mean anything." Danny retorted and kept his eyes fixed on the screen of his tablet. "Chin says they haven't found anything at the house. He's going to bring the lap top to Toast so that he can work his magic, and Charlie is still combing through whatever he could find - specifically tire marks at the end of Lydia's driveway. Toast has come up with a little more than nothing, as he has found Lydia on campus surveillance but no where else. It's like she vanished out of thin air." Danny explained.

`"Have Chin head back to HQ and get to work on everything he can possibly find on Goldstein. I want his employment history, where he studied, everything." Steve ordered.

"You realize we have a little over eight hours to find her based on Austen's profile. We're wasting two sitting here doing nothing."

"That's why we're going to follow him," Steve stated, "and you're going to carry on with your investigation."

"And what are you going to do?" Danny asked moodily.

"Drive the get away car." Steve answered with a little more sass than Danny would have liked.

Danny shook his head and stared down at the tablet in his hands. "The least you could do would be to go on a coffee run." he retorted grumpily.

"Good idea." Steve stated and jumped out of the car. "There's a little place on campus. I'll be right back. Call me if anything changes."

Two hours later with no new information and Steve getting impatient, the students in the lecture hall started to exit the building, Steve spotted Kono in the crowd. She made her way to a bicycle stand, unlocked a bike and pedaled away. Moments later Steve's phone rang.

"All of Goldstein's classes are finished for the day. I'm back at my car." Kono stated after Steve answered.

"He hasn't come out of the building yet." Steve said with a sigh.

"He asked Violet to stay and she did." Kono explained.

"Danny call Violet and get her to come out of there," Steve ordered.

Danny did as he was told. Steve listened for a moment as Austen played along as if she was being called in for a case, and shortly thereafter she exited the building and got into her are and drover away.

Suspiciously, Goldstein followed her and, as he looked over his should and check around him, he snapped a photo of Violet's car with his phone and then fell into his own,

"Well that wasn't suspicious at all!" Danny stated as they saw everything from their locations and he snapped a few pictures of his own.

"Get those to Chin and have him run them through every traffic camera he can think of."

"Already done," Danny stated.

"Kono, follow Violet. We've got Goldstein." Steve stated and discreetly followed the professor away from the university campus.
