The LIDAR was down-aside from the tiny portholes, he was blind. Pressing a palm against the deep cut on his temple and trying not to hyperventilate in fear, he worked the thruster controls.
Nothing happened. While he and Trulli had designed their subs to be sturdy, they hadn’t been intended to resist a deliberate attack, and the electrical control board was flashing multiple warning lights.
He quickly considered his options. He could either reset the affected circuits and try to restore thruster power- or just shut off the electromagnets holding the heavy steel ballast plates to the sub’s belly, an emergency system that would put him back on the surface in under three minutes.
Doing so would mean abandoning the three divers. But he couldn’t help them if he couldn’t see, and the other sub was still out there, its spotlights driving a menacing beam through the porthole as it moved around.
He made his decision, and pulled the red-painted lever beside his seat.

Castille watched in horror as the
Freed of the weight, the submersible shot upwards, spotlights flickering. The fiber-optic line whipped upwards with it, snaking like a cracking whip.
“No!” he yelled helplessly.
As if hearing his shout, the enemy sub swiveled to face him, its banks of spotlights regarding him like glowing compound eyes. The manipulator arm reached back, expertly collecting something attached to a pannier on the steel sideframe before extending again.
Another package, larger than the first. Castille knew instinctively what it was.

Baillard fought to restore power as the
He froze at an unexpected sound. The sub was creaking and groaning as it ascended, but those noises were so familiar that they barely registered. This was something else.
A rhythmic noise, mechanical, coming from the side of the sphere. Where the other sub’s arm had ground against it.
A
Baillard didn’t even have time to realize the full terror of the situation before the shaped charge exploded, ripping a foot-wide hole in the steel pressure sphere. A spear of water hit him with the force of a train, killing him instantly.

Even through his helmet and the thick stone walls of the temple, Chase heard the low rumble. “Shit!”
“What was that noise?” Kari asked.
“An explosion.”
“Are you sure?”
“Oh yeah,” he said. “Either someone dropped a thousand-pound bomb on the
“But we’ll be cut off!”
“We’re
Kari put down the camera and clumsily hurried to him, taking her diver’s knife from her belt. The fiberoptic cable attached to the back of Chase’s suit was sheathed in protective plastic. She grabbed it and sawed away with the knife.
“Come on, come
“I’m
“If the sub blew up, the ballast would’ve been dropped automatically when it lost power. That means the thing’s on its way to the surface like a fucking rocket-and it would have tried to take me with it.” He turned to face her. “Thanks. Sorry I shouted.”
“No need to apologize, given the circumstances!” She looked at the shaft. “If the sub’s been destroyed, what are we going to do?”
“Get the fuck out of here, for starters.” He moved back over to the shaft. “Hugo? Can you hear me? Hugo? Shit!”
“I’m still getting you on the radio,” said Kari.
“Yeah, but you’re standing five feet away in air, and he’s got to receive it through Christ knows how many feet of stone and water. Hugo!”

Castille grabbed the control stick and pushed his suit’s thrusters to full power, shooting upwards in a spray of bubbles as the submersible swooped down at him. It was close enough for him to see the word
The manipulator arm swung at him, but he rolled, using his fins to change direction and duck under it. He looked back, but the pilot was keeping hold of the explosive package, determined to deliver it before dealing with him.
There was only one possible target.
“Edward!” he screamed, knowing there was no chance of being heard. “Get out of there!
The sub’s thrusters spewed out bubbles, the whirling propellers reversing to bring the vessel to a stop at the base of the wall. The arm extended, reaching smoothly into the narrow passageway before retracting again.
The gleaming steel claw was now empty.
Castille put his thumb on the thruster control. If he could get in there fast enough, he might be able to pull the explosives clear.
The submersible pilot wasn’t going to give him the chance. The arm rising above its hull like a scorpion’s tail, the vessel swung around again, hunting for him.
Spotlights dazzled him. Another burst of froth from the sub’s propellers, driving it forwards.
Straight for him.
“Very well…” he whispered. He released the control stick, reaching for his equipment belt.
The submersible accelerated, its arm descending and stretching out ahead of it like a lance.
Castille waited, holding still.
And he whipped up his grappling gun and fired it straight at the cockpit bubble.
The pointed steel tip of the grapnel hit the glass-and stopped dead, penetrating barely more than a centimeter before the force of the water sweeping over the submersible tore it free. It clattered away beneath the sub, trailing its cable behind it.
Castille had already dropped the gun and powered up his thrusters again, twisting to climb over to one side of the onrushing sub. The pilot, startled by the impact, couldn’t react quickly enough to catch him with the outstretched arm.
But he was fast enough to pull the sub around in a sweeping turn, ready to pursue.
Castille knew his suit didn’t have the power to outrun the sub. He just hoped he wouldn’t have to.
In the cockpit, the pilot grinned savagely as he saw the bright yellow shell of Castille’s deep suit pinned in his spotlights. He brought the throttle to full power, preparing to ram him, an underwater hit-and-run…
