She sprang to her feet and opened the door. The sound was louder now and more distinct. It seemed to be emanating from somewhere in the deserted corridor.
'You guys wait here,' Rachel said.
'Where are you going?' Hannah said, her voice tinged with fear after the trauma of seeing two people die only minutes before.
'I need to find out what that sound is. I will be right back. Don't go anywhere unless your parents come back. And keep the door open.'
Rachel walked down the hall, stopping every few seconds to get her bearings on the noise. As she went farther into the building, the pounding got louder, until she was able to zero in on it without stopping. About halfway down the corridor, she rounded the corner to the elevator lobby. It was now obvious where the sound was coming from.
The sound of a voice accompanied the pounding.
'Help! Is anyone out there?'
Someone was stuck in the elevator shaft.
Carrying all of the equipment slowed them down more than Kai thought it would. Time was short as they hurried out of the Seaside's tenth floor stairwell and into the condo.
'We were beginning to think you forgot about us,' Brad said. His voice had a faASSade of cheer, but Kai could sense the despair just underneath the surface. He was trying to keep up Mia's spirits.
'Not a chance, Haole,' Kai said. 'We're going to get you out of there.'
Teresa showed him the jack.
'That's a beautiful sight,' Brad said.
'Let's try it,' she said.
'Wait,' Kai said. 'We don't have time for that yet.'
'What are those for?' Brad said, noticing the scuba tanks.
'For us. All of us.'
'Why don't you get us out first?'
'We have two minutes at most,' Kai said as he cut the rope into ten foot segments with the dive knife. 'We need to get ourselves tied down first.'
'Kai, you're kidding, right?'
'No.' Kai didn't have time to cushion the news. His mind flashed back to Brad trapped in that shipwreck and the panicked rapping at the door before Kai had been able to free him. Brad hadn't been diving since, his fear of the depths approaching phobia.
'I'm not staying here,' Brad said.
'Unfortunately, Brad, you're going to have to.'
'Kai, get us out of here!' Brad began to struggle against the girder. 'I can't stay here.'
'Stop it!' Kai said, trying to calm Brad. He gave the ropes to Teresa. 'Start tying yourselves to the girder. Tightly! It's the strongest thing here. Don't forget Brad and Mia.'
'Why didn't you tell me!' Brad yelled.
Kai leaned closer to speak softly into his ear. 'Because I knew this is how you would react, and you're scaring Mia.'
'But the water!'
'Yes, we're going to be under at least 50 feet of water. I know it's not what you want, but it's going to happen.'
'I can't!'
'You can and you will because there's no other choice. Now are you going to be quiet, or do I have to stick the regulator in your mouth right now?'
Brad's weak nod did nothing to hide his terror.
'What's his problem?' said Tom.
'He had a bad experience scuba diving one time.'
'What happened?'
'He got trapped under water and almost drowned.'
Kai took some of the rope and lashed the tanks to the girder. Only now did it occur to him that they should have also brought buoyancy compensators-the vests that support scuba tanks while diving-to strap the tanks to. He hadn't thought about it while they were in the dive shop even though he remembered seeing some. The nylon rope was certainly strong, but his technique for tying them down was lacking. He had never been in the Boy Scouts, so he was just winging it on the knots. He didn't really care if they would be easy to untie. They could always use the knife to cut themselves free.
Kai was more concerned about the building's structural integrity, but there was nothing he could do about that. Either it would withstand the wave or it wouldn't. All he could do was make sure that if it did stay put, they would too.
'I've got Tom and Lani secured,' Teresa said.
Kai quickly inspected her work.
'Nice job,' he said. 'Those should hold. Let's get Mia and Brad tied up too.'
'Why? They're already stuck there.'
'You don't understand the power of water. The pressure alone might drag one of them out. If that happens, they'd be swept away.'
They rapidly tied the ropes around Brad and Mia together.
'Now it's your turn,' Kai said.
He threw the rope around the girder and encircled her midsection with it.
'What about you?' she said.
'I'll do my own. I want to be next to Lani.'
Tom had already screwed the regulator hoses onto each tank. Each hose had an octopus hose with a second breathing regulator attached to it. In scuba diving, you always had one regulator for yourself and a spare one that dragged along behind you to be used by your buddy if his air ran out.
In this case, that meant they only needed three tanks for the six of them: one for Brad and Mia, one for Teresa and Tom, and one for Kai and Lani.
'Test them out,' Kai said to all of them. 'Make sure they work.'
If they didn't, the only thing they could do was share a regulator, but buddy breathing with the water pulling at them would have been difficult, if not impossible. Fortunately, all of the regulators worked and were delivering air.
Kai secured the dive light to his wrist and snaked the last of the rope around the girder and the life raft. Since they hadn't had time to get Mia and Brad free, they wouldn't have a chance to use the raft with the coming wave. He snapped the nylon strap from Reggie's dry bag-which still held Brad's cell phone, the walkie-talkie, and the photo album-around one of the ropes.
As they finished tying themselves down, Kai heard a sound that was both uplifting and heartbreaking.
'Just in time,' Brad said.
Through the open windows came the sound of beating helicopter rotors hovering directly above them. The chopper Kai had requested from Reggie. He had come through for them, but the timing couldn't have been worse.
Kai wouldn't have left Brad or Mia anyway, even if the helicopter had come earlier, but he briefly considered sending Tom and Lani up. With all of them tied up, it would take them minutes to get untangled and attempt to climb the blast-shattered stairs to the roof. He dismissed the idea, no matter how tempting the helicopter sounded. They'd certainly be caught by the wave before they got to the roof.
After a few seconds, the helicopter crew must have seen that no one was there to be rescued and went on to another building.
'They were so close,' Lani said.
As depressing as the situation was, there was no reason to dwell on it. They had more pressing issues.
'OK, everyone,' Kai said. 'The current is going to be stronger than anything you've ever felt. The important
