Read Chapter 4: The Devil's Trench

The engines cut. The silence that followed was worse than the storm—a thick, waiting quiet that pressed against the hull like something alive. Mack stood at the helm, knuckles white on the wheel, staring at the depth sounder. Three hundred feet below, the trench bottomed out into a darkness that swallowed the sonar ping whole.

Abigail leaned over the chart table, pencil tapping against the weathered coordinates. "This is it. The Devil's Trench. Blackwood's map puts the wreck at the base of that southern wall, where the current scours the sediment clear."

Mack grunted. The water was the color of old iron, churning with silt kicked up by the storm that had nearly torn them apart. The sky had cleared to a sickly yellow, but the sea hadn't forgiven them yet. Neither had his nerves. The blip on the radar—that impossible brigantine silhouette—had lingered for eleven minutes before vanishing. Eleven minutes of Abigail screaming coordinates, Tomas shouting that the instruments were lying, and Mack feeling something cold crawl up his spine like a memory trying to resurface.

"You okay, Captain?" Tomas emerged from the engine room, wiping grease from his hands. "The anchor's holding. But this water's wrong." He sniffed. "Too still."

Mack forced a grin. "Still's good. Calm seas."

"Calm seas don't smell like that."

Before Mack could answer, Rosa's voice crackled over the radio from the galley. "Captain, we've got company. Northwest. A boat, and it's not a fishing vessel."

Mack stepped out onto the deck and followed her pointed finger. A forty-foot salvage trawler cut through the swell, bow spray white against the gray. It was all business—winches, a dive platform, and a radar mast bristling with antennae. On the bridge, a man in a white linen suit watched them through binoculars.

Mack knew that suit.

"Son of a bitch," he muttered.

Vincente Cruz. The man ran salvage operations out of San Juan, and he had the reputation of a barracuda—fast, toothy, and disinclined to share anything that swam in his waters. He'd cost Mack a contract two years ago by underbidding on an old freighter, and he'd done it with that same smug grin he was probably wearing right now.

The trawler pulled alongside, engines rumbling as a crewman tossed a line. Cruz stepped onto the deck with the ease of a man who'd never once been wrong in his life.

"Donovan." Cruz spread his arms. "Fancy finding you here, in the middle of godforsaken nowhere, circling a hole in the ocean." He smiled, showing too many white teeth. "You're not trying to poach my wreck, are you?"

"Your wreck?" Mack folded his arms. "I've got a permit and coordinates that say otherwise."

"Ah." Cruz reached into his jacket and pulled out a laminated document, waving it like a fan. "And I've got a permit from the Turks and Caicos government. Signed, sealed, and stamped. Salvage rights to a designated eighteenth-century shipwreck of historical significance. That's my cargo, my site." He tilted his head. "You read this date? It's effective as of this morning."

Abigail stepped up beside Mack, her eyes narrowing as she scanned the document from a distance. "That's a forgery," she said flatly. "The Turks and Caicos doesn't issue permits on a Sunday. And the seal's wrong—the crown's tilted."

Cruz's smile flickered, just for a second. "Your lady friend can read documents all she wants, but I've got the paperwork. You've got—" He glanced at Mack's hands. "What have you got?"

Mack pulled out his own permit, weathered and salt-creased, the official embossed seal catching the pale light. He'd fought for it, paid a bribe to get it expedited, and it was the only legal leg he had to stand on. He held it up. "Recognize this? Royal Salvage Authority, chain of custody signed by the deputy minister himself. My wreck. My claim."

Cruz studied the paper for a long moment. The crew on his boat had gone quiet. The only sound was the slap of water against the hulls.

"This trench," Cruz said slowly, "is a graveyard. Men don't come back from it. You want to dive alone in a hole that dark, with gear that looks like it's been through a war—" He shrugged. "Go ahead. I'll be watching. And if you don't come up, I'll take the wreck as salvage anyway. Insurance covers acts of God." He laughed. "Or acts of the Devil, as the case may be."

He turned, barked an order, and his crew cast off. The trawler pulled away but hovered at a distance—close enough to watch, far enough to claim plausible deniability if anything went wrong.

Tomas spat over the rail. "That man's a shark in a suit."

"He's a scavenger," Mack said. "And he's not wrong about one thing. It's a graveyard down there." He looked at Abigail, whose face was pale beneath her sunburn. "But I didn't come this far to turn back because of a bad feeling."

Mack suited up alone. Rosa helped him into the harness, her fingers moving with practiced efficiency, but her eyes said something else. She'd been quiet since the storm, since the radar blip, since she'd whispered something to Abigail about the navigation charts that Mack hadn't caught.

"Be careful, Captain," Rosa said. "The dead don't like being disturbed." Her accent thickened when she was frightened.

"I'm not disturbing them," Mack said. "I'm just borrowing a coin."

The water swallowed him. Cold hit his skin through the wetsuit, a sharp intake of breath that fogged his mask. He clicked on the dive light, and the beam cut through swirling sediment like a knife through smoke. The descent was slow, deliberate—checking the line, the pressure gauge, the timer.

At a hundred and eighty feet, the wreck emerged from the gloom, and Mack stopped moving.

She was bigger than he'd imagined. The Santa Catalina lay on her side, keel snapped amidships, hull furred with coral and barnacles. Her nameplate was still visible in places, brass letters green with patina: SILAS BLACKWOOD'S flagships. The masts were gone, snapped off like broken fingers, but the bowed hull was intact aft of the break—and there, below the waterline, was the hole.

Not a gash from rocks. A clean, circular hole, large enough for a man to swim through. Too deliberate for accident. Too smooth for damage. It looked, Mack thought, like something had drilled its way out from the inside.

He hovered at the opening, playing his light across the edges. Barnacles had grown thick around it, old growth—this hole had been there for a long time. But his instincts prickled. Something about the angle of it felt wrong, like a wound that had healed wrong on a corpse.

He swam through.

The interior was a cathedral of darkness and silt. Casks rotted to mulch. A bronze cannon lying half-buried in sediment. And there, tucked beneath a collapsed beam, was the chest.

Iron-banded, oak-still solid after two centuries. Blackwood's insignia was carved into the lid—a serpent eating its own tail, wrapped around a cross.

Mack's heart hammered as he worked the lock free. It had rusted through, crumbling at the touch of his dive knife. He lifted the lid.

Gold. Not the dull gleam of old coins, but a warm, bright glow that seemed to push back the darkness, illuminating the interior with a light that wasn't entirely reflection. Doubloons, stacked in neat rows, caked with sediment but luminous underneath.

He reached in and took one. A single coin, heavy and warm despite the cold water.

And then the whisper came.

It wasn't sound, not really—a cold breath against his ear, the faint pressure of lips almost touching his skin. The words were old, shaped by a dead tongue, and yet he understood them.

*Blood releases the lock.*

The water around him seemed to thicken. The light from his dive lamp flickered, and for a moment, he was certain he was no longer alone. Something moved at the edge of his vision—a shape, tall and gaunt, watching from the shadows of the collapsed beam.

Mack kicked backward, heart pounding, and swam for the hole. He burst out into open water and hauled himself up the line with arms that shook. He didn't look back. He didn't dare.

When he broke the surface, gasping, Rosa's hands were already pulling him over the rail. Tomas helped him unstrap the tank, and Abigail hovered at the edge of the deck, face tight with worry.

"What did you see?" she asked. "Was it there?"

Mack pulled off his mask. The coin was still clenched in his fist, warm against his palm. He didn't open his hand.

"The wreck's there," he said, voice rough. "We've found it."

He said nothing else. But the cold breath on his neck didn't fade, even as the sun broke through the clouds above.
