Cabrillo had his doubts. But there was no other way. Her cabin door would have burst and flooded the ship had they cut their way into the room. She would have drowned long before they could have made a hole big enough to even pass her a regulator. No, he thought, this was the only plan that could work.

He tapped his rhythm against the steel with his light again and again. Then he thought he heard something from within the ship. He tapped again, “Shave and a Haircut,” pulled off his hood, and pressed his ear against the door.

There. The unmistakable reply. Tap tap. Two bits. She’d made it.

He reached into the basket of tools he’d requested from the Oregon. First, he checked that the spare scuba tanks were ready. Next came the drill, which fed off two compressed air cylinders slung under the wire-mesh cage and attached by a long hose. The tip was specially hardened and at the RPMs generated by the air tanks would cut through the door in seconds. Cabrillo looked around. The divers at the stern must have finished securing the cable sling to the Avalon. A pair of them went to help those working at the bow while another two came over to help him.

Cabrillo braced his back against the heavy basket, pressed the drill bit near the bottom of the door, and pulled the trigger. The piercing whine was like actually standing on a tooth while a dentist went after a particularly nasty cavity. It drove spikes through his ears that met in the middle in a blinding point of pain. He ignored it and watched silver slivers of metal curl away from the drill point. In just a few seconds the tip bored through, and Juan carefully removed the drill from the hole. Water and bits of the shavings were sucked into the ship. He didn’t know the size of the antechamber and couldn’t guess how long it would take to fill, so all he could do was wait until the pressure had equalized enough for him to open the door.

He used a metal pry bar to tap at Tory and tell her he was with her. Her reply came instantly and angrily. She hadn’t expected that this was how she’d be rescued.

After four minutes, Juan pulled at the door with the pry bar, but it remained sealed tight, so he drilled two more holes and tried again every minute afterward with the same result. He was about to drill a few more to hurry the operation when something happened.

A sudden gush of bubbles exploded from someplace ahead of the superstructure. The louver in the fore hold had given way, and thousands of gallons a minute poured into the derelict. The quick rise in pressure had popped an inspection hatch on the main cargo hatch. The six divers working at the bow appeared from over the Avalon’s squat funnel, fighting their way through the maelstrom of bubbles and surging water. One of them made a cutting gesture across his throat as soon as he was within the circle of light cast by the undersea lamps. They hadn’t completed securing the forward sling.

In moments the Avalon began to drop by the head. And then she started to roll to port. The divers had managed to secure only the starboard side of the sling. The Avalon was held to the Oregon by three cables, two aft and one forward. For a few moments the ship appeared to stabilize, but her off-kilter angle allowed water to enter from other places. The crane operators on the Oregon, no doubt supervised by Max, gamely tried to hold the ship steady for as long as they could, but it was a losing battle.

Cabrillo had floated free from the deck in those first frantic seconds but quickly dropped back to the door. The basket of tools had slid all the way to the scupper. He motioned for one of his men to retrieve it while he hauled on the unyielding hatch.

Tory would have been tossed around inside the antechamber when the ship torqued over, and her new angle meant she’d have to tread water until he could get the door open. It was a race against the clock, and time had just accelerated.

The cable sling at the bow was looped to one of the ship’s mushroom-shaped cast-steel bollards. The free end was caught in a jet of air bubbles and danced around the rigging holding the Avalon’s forward mast. Because of the uneven load, the cable pulled at the top of the bollard and started to slip off. The steel strands rasped as they were drawn over the top of the bollard, a pitiable cry like a mountain climber at the moment his grip slips from a rock face.

With water gushing into the forward hold, the cable remained taut for a few seconds more before sliding off the bollard. The Avalon’s bow plummeted, tilting the ship through ninety degrees until she dangled nose down from the straining crane aboard the Oregon, her knife-edged prow pointing into the abyss. Rated for sixty tons, the crane was probably fighting to hold three times that weight, and every second increased the strain.

Because of water resistance, the ninety-degree rotation had taken a few seconds, long enough for Juan to clutch the door as the deck became a wall and the aft bulkhead became the floor. Then there came a scraping sound, one that tore through the water and seemed to come from every direction. Juan frantically looked around for the source. The light towers his crew had erected were still tumbling across the deck, creating a nightmare effect of glare and blackness. The sound grew louder. Juan glanced up to see a lifeboat that had pulled free from its davits hurtling down the length of the ship. He dove to the side as it raced past, its momentum pulling at him like a whirlpool. The davit cables trailing the lifeboat were a thick tangle of inch-thick rope that caught him just as he looked back to see if his people had avoided the speeding projectile. The knot of rope slammed into the back of his head, tearing off his face mask.

He fought the pain and disorientation, groping for the mask as it swirled in the black eddies. He opened his eyes, the sting of salt worse than any he’d ever felt. But there, just beyond his fingers, the orange mask was slipping into the depths. He grabbed it, snapped it back over his face, purging it by tilting his head and allowing air from his regulator to expel the water. He swam back to the door, checking his wrist computer. The Avalon was sinking at ten feet a minute and accelerating. He knew Max would run out every foot of cable on the Oregon to slow her descent, but there were limits to how deep they could breathe off compressed air.

The other diver had been thrown violently when the ship upended. It took him a few moments to clear his head and find the tool chest where it had lodged against the rail near the ship’s jack staff. He didn’t bother with the drill and instead concentrated on taking the spare air tank and a dive bag up to the chairman.

Together they heaved against the door with the pry bar. A curtain of bubbles exploded around the seam for a second. They’d managed to open it a crack, but pressure slammed it closed again. They pulled harder. Juan felt as though the muscles of his back were being stripped from his bones, and black stars exploded behind his tightly closed eyes. Just as he was about to stop and shift to a new position, the door swung open, instantly flooding the last of the interior space.

The powerful lights they’d set on the aft deck had either smashed themselves to pieces or were lost over the fantail, so all he had was his trusty dive light. He swung the beam around the antechamber. The space was cramped, painted a drab white. A set of metal stairs dropped to a solid-looking hatch that had once led to the bridge deck. Another door to the right that gave access to the interior of the main deck had also been secured. Then he saw Tory, a dark drifting shape of sodden clothes and loose limbs. Her hair fanned around her head like an anemone on a tropical reef.

In two swift kicks Juan was at her side. He slid his regulator past her slack lips and upped the airflow, trying to force the precious gas into her lungs. The other diver joined him and ripped open his dive bag. As fast as he could work, he plucked fistfuls of chemical warming packs from the bag, shook them violently to start the reaction, and stuffed them under Tory’s clothes. They had several decompression stops to make on their ascent, and this was the only way Juan could think of to protect her from the biting cold.
