The Hoenigs and Harry woke up fairly early the next morning and had a quick breakfast. Robby called Mike Lam and related to him his suspicions about the red-headed man, adding that it might not mount to anything.

"That's perfectly fine," said Mike. "And thanks for calling me to tell me this. Even if this might not help solve Jack's disappearance, it could solve another crime. One can never know when a clue would take us in the right direction."

Robby chuckled. "My grandpa said the same thing."

"I'm sure he did, I must have mentioned it to him a hundred times by now."

"Wow, you like hanging out at ICS a lot, huh?"

"Yeah, well, um, ahem, they're a bunch of good people. Listen, thanks again for the information, we'll look into it, but I need to go now."

"Oh, um, OK. Thanks Chief!"

"Thank you." Mike hung up.

After Robby finished his call, the family set out to ICS. The boys were eager to get started on their little excursion. They wondered what they would find, if they found anything.

"Mom, Dad, are you absolutely sure that Poipu was harmed by a harpoon?" asked Robby when the group were on their way to ICS.

Miriam turned in her seat to face her son, a questioning look on her face. "Yes, why?"

"Just to be sure. There wasn't a harpoon hanging out of his side or anything, so someone could say that we possibly couldn't know."

James nodded before shooting a glance at Robby in the rearview mirror. "That is a good point, especially since you witnessed Poipu coming in and didn't see it yourself."

"So, how did you figure out it was a harpoon?" asked Harry.

"Well," began James, "would you rather see the process for yourself at ICS, or just have us explain it to you right now?"

The boys glanced at each other. Harry grinned. "Eh, I kinda want to see."

Robby sighed, but he was smiling. "Oh, alright, I admit I want to know as well."

Miriam smiled. "Alright then. But we can't show you everything, can't give you a leg up on all your college classes."

Robby's mouth dropped. "But Mom!"

James scoffed. "Don't argue with your mother, Robertson Allen Hoenig, or we could just not show you at all."

Robby huffed. "Yes sir."

"Thank you."

When they pulled into the parking lot of ICS, Jacob and Dr. Cho were just opening up the lab. He waved at them while the rest of the employees went inside. Irene waited for them by the door.

Jacob walked up to the car. "I've already talked to Billy, Irene, and Stan. Irene and Stan are willing to go along, and Billy said he'd have the boat and diving gear ready for you in about an hour."

"How much will it be?" asked James.

Jacob waved his hand. "I've already got it covered."

"Dad! You can't keep buying us everything while we're here!" exclaimed Miriam.

"I know, I know, but Billy did give me a discount. How could I turn that down?"

Miriam rolled her eyes and groaned. "Oh, fine."

"How will we get to Uncle Billy's?" asked Harry.

"Stan will drive," said Jacob, "he's got his own Jeep. But he's got a few duties to attend to before he can leave."

James opened the door and stepped out of the Jeep. "Well, then we should have enough time to show you."

Jacob glanced between James and Miriam. "Show them what?"

Miriam got out of the Jeep and walked around to the driver's side where her husband and her father were standing. "They wanted to know how we were able to find out that Poipu had been harpooned." Harry and Robby got out of the Jeep as well and joined them.

"Yeah, Robby didn't see a harpoon sticking out of Poipu," said Harry, "and some people will take that to mean it didn't happen."

Jacob nodded, impressed. "Good thinking. Come on then, let's show them." They walked towards the door, and Irene opened it for them. Jacob smiled at her. "Why, thank you very much, Irene."

She returned the smile. "You're welcome." She smiled at James and Miriam when they walked past, but when the boys stepped near, she seemed to turn on them with a growl. They were taken back by the change, but they quickly walked in. She closed the door and walked off towards the museum.

"What's gotten into her?" whispered Harry.

"Still sure you want to go out with her?" asked Robby with a mischievous glint in his eyes.

Harry scoffed. "Yeah, about that, I'm beginning to rethink that. But still, what's gotten into her?"

Robby became serious as he took a quick glance at the door she went through. "I don't know, but I hope we can find out and work it out together. We're supposed to be on the same team." He glanced at Harry. "Maybe it's because we're going to Devil's Hat?"

A thoughtful look came over Harry's face. "It's possible, she did want us to stay away from it, right? That was why she was telling us all about those ghost stories."

Robby nodded. "Yeah, and it looks like we've got more than one person acting odd on this island."

"The weird guy still on your mind?" asked Harry.

"Yeah, kinda," was all Robby said before they entered the lab where Jacob, James, and Miriam were waiting. They were laying out papers and pictures on the table. Robby picked up one. It was a picture of Poipu's wound. It looked rather circular.

"That's one major way to know it was a harpoon," said James. "Rocks would leave such a round wound, and definitely not a bite. You would have seen the teeth marks. " He placed another piece of paper in Robby's hands. "Since we also took measurements of the wound, we were able to determine the size of the harpoon head."

Jacob huffed. "And by these measurements, it's a common harpoon gun in these parts. It really could have been anyone."

"Even a fisherman who was aiming at another fish?" asked Robby.

James nodded. "It definitely looks like it."

"So it could mean that it was an accident," said Miriam, "but it was also possible that someone was trying to scare off Poipu so they could fish without him scaring all the fish away or eating them."

"But they didn't come forward?" asked Harry.

James shrugged. "They might not have known Poipu was from the lab, they could have thought it was just a regular dolphin."

"Either way," said Jacob, "we can't let people harm dolphins and expect to get away with it. Plus this is an ICS dolphin, we need to at least give the person who did this a warning. They do it again, they will be charged with animal cruelty."

Robby nodded. "That sounds fair."

Harry placed his hands on the table. "So, now that we have this information . . . it really does seem like it could be anyone. How can we narrow it down?"

Jacob shrugged. "I guess just start off with asking people how they are doing and what they were doing yesterday morning. And since Robby didn't see any sharks in the water yet, it had to have happened not long before Kalea heard him." Hu let out a breath. "I just wish we had gone out right then and there to find out instead of waiting a day."

Miriam rubbed his arm. "Well, we were focused on saving Poipu, and there was the issue of Jack Storm missing. Since we have the police taking care of that angle, we can have the boys focus on this."

"Yes, but the trail has gone cold, and they might end up on a wild goose chase," said Jacob.

"But," said Harry with a raise of his hand, "had we gone out there yesterday and just started asking people, they would have been on their guard. Today, someone might let it slip about hurting Poipu."

Jacob blinked. "Why, that is a good point."

Robby grinned. "Baywatch has some psychology mixed in. You wait long enough, and the truth will come out."

"Yes, provided that you're actively looking for it at the same time," pointed out James.

"True that," said Harry.

"There you two are." Stan and Irene walked into the room. "I'm finished with my duties, want to head out now?"

Robby glanced at Harry before they turned to Stand and Irene. "Sure, the sooner the better." He turned to his parents and grandfather. "We'll see you later!"

Harry waved as they walked out the door. "Hopefully we'll bring in the person who did this!"

"But no guarantees," added Irene. She smiled. "But we'll do our best."

"That's all I'm asking," said Jacob. He waved. "Good luck!"

"Bye!" they chorused before heading out. They followed Stan to his own Jeep and got in quickly. He pulled out and they were on their way.

Robby was itching to ask Irene what her problem was, but couldn't find a good way to lead into it and it didn't feel right to just come out with it. He glanced at her, sitting in the front seat next to Stan. She did want to find out what had happened to Poipu, right? Or was she upset that he and Harry were tagging along when she had just wanted it to be her and Stan. Yet, the two didn't seem like they were romantically interested in each other, just friends. So, what was her deal?

Harry was wondering the same thing, and wondering why he even still hoped she might become interested in him. She was worried about something, that much he had figured, but what she was worried about she seemed to hold on tight, refusing to let anyone else know. Did her sisters know? What was he thinking, they probably did, gossiping all night about it too. Especially if they were anything like his sisters, fighting one minute over a piece of clothing and whispering secrets to each other the next. Maybe, if he and Robby just let her know that they were trustworthy, she'd relax a bit and let them in on it. Until then, he figured they would just have to deal with more stink eyes.

The trip to Uncle Billy's wasn't completely silent, Stan did remind them that they were supposed to be pretending to be tourists with Stan and Irene showing them around. They could ask questions a little more casually so as not to make anyone suspicious and clam up. But the rest of the time, everyone seemed lost in their own thoughts. It wasn't until they had gotten to Uncle Billy's that things seemed a little different between the four.

"Well hello there, welcome back!" said Billy with his hand outstretched to Robby.

Robby shook it and smiled. "Glad to be back!"

Billy beamed. "You like my joint, huh?"

"Well, it is a little more comfortable than Kailoa's," said Harry as he shook hands with Billy. "Kailoa's might be a fancy place, but this just feels more, well, friendly and laid back. My type of place."

Billy's grin grew wider. "Then this is definitely the place for you!" He turned to Robby. "You feel the same way?"

Robby bobbed his head. "Oh definitely, and more fun at that."

Billy laughed. "You guys sure like buttering me up, don't ya?"

"But we're being honest!" exclaimed Harry.

"Oh I believe you, don't worry, it's just not everyday someone prefers my place to Kailoa's." He snickered. "Then again, I'm the only restaurant that lends out boats and scuba gear. And yours is all set, come on." Billy stepped out from behind the counter and led the group to the docks. There was a boat that was equipped with scuba gear, supplies, and a cooler.

"Grandpa ordered us lunch too?" asked Robby as he got on the boat to look inside the cooler. There were sandwiches and drinks sitting atop a mound of ice.

"Yup, he sure did. Wasn't sure how long you would be out there and figured it best to make sure you had something to eat than not." He patted the boat's stern. "And she's got a tank that can take you around Devil's Hat and back." But then he narrowed his eyes and pointed threateningly at them. "Now remember, you're only out there to pretend to be tourists so you can figure out what happened to Poipu, don't go adding treasure hunting to that list, you hear? That's my thing and I aim to find that treasure, understand?"

Robby and Harry gulped. "Y-yes sir." Stan had spoken the words as well as Robby and Harry. Irene was smiling from ear to ear.

Billy then grinned broadly. "Good! Then you're all set! Contact me if you have any problems with the fishermen, the boat, or the gear."

Stan jumped on board the boat before saluting Billy. "Yes sir!" Irene got on board. Billy untied the boat and gave it a little push. Stan turned on the engine and the boat pulled away from the dock.

"Good luck to you! Be safe!" He waved.

"Thanks!" said Robby as he, Harry, and Irene waved back. Billy turned and walked back into his store.

Harry let out a low whistle. "Man, he's really serious about finding that treasure."

"Yeah, and the fact that he's been looking for it for three decades means he's never going to find it," said Stan. "If he hasn't found it by now, then the thief did come back and took it from its hiding place before he hightailed it out of Hawaii." He shrugged. "Which could mean that that treasure has long been sold off to other buyers on the black market."

Robby shrugged. "Well, we weren't out here for the treasure anyways. Poipu is the most important part."

"Well, besides the missing Jack," pointed out Harry. "If he is missing, he could be in hiding."

"But hiding from what?" asked Irene.

Robby and Harry slowly glanced at each other. "I think we should tell them," said Robby.

Harry shrugged. "It's up to you, man, you're the one who saw the whole thing."

"Tell us what?" asked Irene and Stan at the same time.

Robby sighed. "There, there was another reason why I felt more comfortable at Uncle Billy's." He told the whole story about seeing the red-headed man at Kailoa's and how it creeped him out.

When he finished his story, Irene wrapped her arms around herself and shivered slightly. "He seems like a horrible man."

"You've never seen or heard of him before?" asked Harry.

The two Hawaiians shook their heads. "No, doesn't sound like anyone I've met in town," said Stan, "and I'm pretty sure I've met everyone. I don't know everyone, but I know I've met everyone. This is my hometown, after all."

"Same for me," said Irene. She pursed her lips. "Maybe he's the one we really need to find, he could be behind all this!"

"Well we should keep a look-out for him," said Robby. "If just to see what he's really up to." The others nodded.

"Yeah," agreed Stan, "and if he is how you think he is, he's going to be very untrustworthy. He could even be a pirate!"

"A pirate?" exclaimed Robby and Harry.

Irene scoffed. "Stan, pirates haven't been seen in these parts for generations. And if they're here for the treasure, they would have been here ages ago." She paused for a moment. "Which could mean that the treasure was retrieved by the thief."

Stan shrugged. "Eh, it's a possibility. But the outfit Robby described does sound an awful lot like an old pirate outfit, don't you think?"

Irene shrugged. "Yeah, kinda does, but it really doesn't make sense for them to come here now."

Stan brought the boat to a stop. "Yeah, true. Well, why don't you two start acting like tourists? I can see a few fishermen sailing around Devil's Hat. Oh, and I see Dr. Finski's boat too. I hope he doesn't try to call out to us and blow our cover."

"Then we'll just have to stay out of sight while these two are touring," said Irene.

Harry straightened up with a huff. "Oh alright, Mr. Tour Guide. Get me all excited about pirates after Uncle Billy tells us not to go looking for treasure." Stan chuckled and winked. He and Irene helped the boys get into the scuba gear before helping them climb down into the sea. Robby and Harry swam under the boat for a little bit before going deeper to look at the coral reefs.

Robby couldn't help but smile when the reefs came into view. Sure, the station he called home was further out at sea and they couldn't see the reefs from where they were, but the reefs still made Robby feel like he was where he belonged. He and Harry watched the fish swim by. Harry tapped Robby's shoulder and pointed. He noticed a dolphin hanging around near Dr. Finski's boat. The dolphin seemed to notice them too. The boys waved at the dolphin. The dolphin seemed to wave back. Robby glanced up at the ICS boat and noticed several more boats were coming into the area. Fishing boats and probably, hopefully, more tourists. Harry tapped him again and pointed back to the dolphin. Robby looked at the dolphin. He blinked. Was the dolphin trying to tell them something? He and Harry began to swim towards the dolphin. At that moment, something whizzed through the water and punctured Robby's air hose. Someone was shooting a harpoon gun at them!

(Author's Note: Ugh, oops, I did it again . . . I'm leaving you with a cliffhanger! lol, typical me. ;P But I just hope this means you'll be back and hungry for more come July 5th! See you all then! Take care, and God bless!)
