The Gulf of Mexico had a way of turning brass into chalk and honest men into liars, but Gage Sullivan figured he had built a reasonably durable immunity to both. He leaned over the starboard gunwale of the Restless, watching the greasy bilge water curl into the emerald chop three miles off the barrier islands of Mississippi. The air tasted like warm zinc and dead oysters, a familiar soup that meant August was doing its usual work on the coast.

His boat was forty-two feet of scarred cypress planks and fiberglass patches, powered by a rebuilt Detroit Diesel that rattled like a tin can full of dry bolts. To the tourists who paid for afternoon dolphin charters out of Biloxi, she looked like an abandoned dock float with a wheelhouse. To Gage, she was thirty tons of paid-for leverage, capable of winching sunken skiffs off the sandy bottom or pulling shrimp nets through black mud until the cables whistled.

Beside him, T-Bone was hacking the heads off menhaden with an eight-inch fillet knife that had been sharpened so many times the blade curved like an unbent paperclip. T-Bone’s real name was Clarence Thibodeaux, but nobody had called him that since an offshore derrick snapped his collarbone back in ninety-eight. He was sixty, entirely deaf in his left ear from too many unvented surface-supplied air dives, and possessed the uncanny ability to smell cold beer through a locked cooler lid.

"You're burning daylight, Cap," T-Bone said, not looking up from the cutting board. He swatted a greenhead horsefly off his forearm with the greasy flat of his hand. "Radio says the squall line out by Dauphin Island is already kicking up four-foot rollers. We don't get this transducer locked into the shoe, we’re going to be reading mud all afternoon."

"The transducer is fine," Gage said, wiping sweat from his eyebrows with the sleeve of an ancient faded chamois shirt. "The seal around the stuffing box is what's sweating. If the shaft starts chattering again, we'll lose reverse before we clear the channel shoals."

"She’s survived thirty years of you wrenching on her with the wrong size sockets. She ain't quitting today." T-Bone kicked a plastic bucket full of chopped chum toward the transom. "Besides, we got company coming up fast off the port quarter. Big company. Smells like twin Caterpillar diesels and money your daddy never had."

Gage straightened up, feeling the vertebrae in his lower back pop in sequential protest. He shaded his eyes against the white glare of the noon sun. A plume of pale exhaust rose against the southern horizon, right where the dredged deep-water shipping channel met the open shelf. Cutting through the gentle swells was a seventy-foot aluminum beast with an enclosed flybridge, sleek outriggers, and a navy-blue hull that reflected the flat water like polished glass.

The Vanguard.

She belonged to Nolan Vance, a man who had made his first million running offshore supply contracts during the late-nineties oil boom and his subsequent ten million by aggressively litigating maritime salvage claims from Galveston to Key West. Vance didn't just salvage wrecks; he devoured them with attorneys, heavy-lift cranes, and state-of-the-art multi-beam sonar arrays that cost more than Gage's entire estate, boat and trailer included.

The Vanguard didn't alter her course as she approached. She came straight on, pushing a broad, foamy mustache of water ahead of her prow, throwing a five-foot displacement wake that set the Restless rolling heavily in the trough.

"Arrogant son of a bitch," Gage muttered, grabbing the iron handrail bolted along the wheelhouse roof.

The deck lifted sharply beneath them. Buckets slid against the scuppers, and a loose socket rolled clattering into the cockpit gutter. Gage stood his ground, letting his knees take the heave, while T-Bone merely shifted his weight from hip to hip without lifting the knife.

The big aluminum boat slowed abruptly as she drew abreast, the deep, throaty rumble of her underwater exhausts churning the water into frothy ginger ale. Up on the flybridge, behind tinted wraparound Lexan, a deckhand in matching khaki shorts and UV-blocking tech shirts threw a reverse gear. Another man stepped out onto the bridge wing, holding a stainless-steel mug with one hand and resting the other on the lacquered teak rail.

Nolan Vance looked like an advertisement for an expensive skin clinic. He was forty-eight, razor-shaved, with thick silvering hair cut tight against his temples and polarized sunglasses that hid his eyes. Behind him, leaning against the radar mast, stood an older man in grease-streaked coveralls whom Gage recognized immediately: Perry Finch. Finch had been diving the Gulf wrecks since the days when men still used double-hose regulators and lead-soled boots. Finding Finch on the Vanguard was like finding an alligator in a swimming pool; he was entirely out of place among Vance’s shiny chrome fixtures, which meant Vance was paying him an obscene amount of cash.

"Afternoon, Sullivan!" Vance’s voice boomed down from the wing, carried by a low-volume hailer mounted on the cabin overhang. "Looks like you’re taking on water again. You need a tow back to the harbor before the tide turns?"

"We’re doing just fine on our own bottom, Vance," Gage shouted back, voice calm and level. "How’s your steering pump? Sounded like a dying sow when you came off plane."

Vance smiled, flashing teeth so white they looked painted on. "She runs smooth enough to find what you've been stepping over for five years. Tell me, Gage—have you looked at the weather fax this morning? Or do you still rely on your arthritic elbow to tell you when the sky is falling?"

"Sky looks blue enough right now," Gage replied. "Though I reckon you'll run for safe harbor the minute your air conditioning gives out."

Vance chuckled, taking a sip from his mug. He leaned down slightly over the railing, dropping the false bonhomie just enough for the edge to show through. "Tropical Depression Four just cleared the Yucatan strait. The National Hurricane Center says it's going to track into the central basin by tomorrow night. Sustained winds already sixty miles an hour. It’s going to churn up the whole shelf, Sullivan. Break up the sand bars. Scour the bottom right down to the caprock."

"I know how the shelf works."

"I’m sure you do," Vance said smoothly. "Which is why I’m giving you a professional courtesy. Stay west of the Chandeleur light. If I catch that rusted wood-tub of yours dragging iron across my survey grid, I won't bother filing with the admiralty court. I'll just hook my stern winch to your mooring bits and drag you back to the Biloxi marsh myself."

Before Gage could answer, Perry Finch shifted his weight by the radar mast. The old diver caught Gage’s eye for a fraction of a second, his weathered face deadpan, then made a subtle, downward flick of his left hand, pointing three fingers toward the deck before disappearing into the companionway. It was a diver’s signal—three fathoms, or thirty feet, or perhaps bearing three-zero-zero. It was gone as quickly as it appeared.

Vance stepped back to his throttle console without waiting for a rebuttal. "Keep an eye on the barometer, boys. Wouldn't want you getting wet."

The Vanguard’s stern dug deep into the water, her twin screws biting hard, throwing a deafening roar and a white wall of spray that soaked the Restless’s port side. In ten seconds, the big yacht was climbing onto plane, carving a sharp white furrow toward the southeast, out toward the open, deep-water leases where the continental shelf tumbled down into the abyss.

T-Bone spat into the scupper, watching the yacht dwindle against the horizon. "He’s got a mouth on him, that one. Some night somebody’s going to sink a four-inch bronze lag bolt through his hull below the waterline, and he’s going to wonder why his bilge alarms didn't go off until his feet got cold."

"He didn't come out here to insult our boat," Gage said, his pulse still hammering against his collar. "Vance doesn't burn four hundred gallons of diesel just to tell me to stay out of the Chandeleurs. He’s nervous."

"Nervous about what? He’s got five million dollars in credit lines and a boat that can do thirty knots in four-foot seas."

"He’s nervous about Finch," Gage said. He walked across the deck, stepping over the coils of yellow retrieval rope, and climbed the three steps into the cramped wheelhouse.

The wheelhouse smelled of stale tobacco, copper grease, and the dry, paper-scented warmth of vacuum tubes. Mounted above the helm was an ancient Furuno paper chart recorder, its stylus clicking rhythmically as it burned charcoal-colored lines onto a slow-moving roll of coated paper. Below it sat an open brass marine barometer, its needle hovering right around 29.95 inches of mercury. Gage tapped the glass gently with his knuckles; the needle shivered, settling slightly lower, resting on the downward curve.

T-Bone followed him in, wiping his greasy knife blade on a scrap of rag. "What did Finch do? I couldn't see past Vance’s teeth."

"Finch gave me the mark," Gage said quietly. He pulled a yellowed, water-stained navigational chart of the Mississippi Sound from the chart table drawer, smoothing the curled edges down with his thumbs. "Look here. Vance has been running grids off Horn Island for two months, claiming he’s looking for old oil field debris for an environmental mitigation contract. That’s pure smoke. He’s looking for the Santa Rosa."

T-Bone gave a short, dry bark of laughter. "The Santa Rosa? Man, people have been drowning over that ghost ship since the Civil War. She sank in 1794. If there was any wood left on her, the shipworms ate it before Louisiana was even a state. There’s nothing out there but iron ballast stones and empty shells."

"The ballast stones don't wash away," Gage countered, his finger tracing a curved contour line that marked the outer edge of Dog Keys Pass. "And the Spanish mint at Veracruz wasn't shipping empty shells. Three hundred boxes of silver reals and church plate from the Havana treasury. When the hurricane of ninety-four drove her onto the shoals, she didn't break apart in deep water. She came down right on the outer reef bar, took two heavy rolls, and then the sand swallowed her whole."

"Yeah, under thirty feet of shifting Mississippi mud," T-Bone said, squinting at the chart. "Which brings us back to Finch. What was the hand signal?"

"Three-zero-zero," Gage said. "Or maybe thirty fathoms. But there aren't thirty fathoms anywhere within twelve miles of the islands. The shelf drops off slow out here. Thirty feet, though—thirty feet is the deep trench running right along the south lip of Petit Bois Island where the currents undercut the sand during an east wind."

Gage picked up a worn brass pair of dividers, walking their sharp legs along the latitude scale. "Finch found something. Or Vance thinks he found something. Finch owes me, T-Bone. He owes me for pulling him out of the decompression chamber at Mobile when his dive tender walked off the job drunk three years ago. He wouldn't drop a marker for Vance unless he was being paid under the table, and he wouldn't flash it to me unless he wanted me in the water."

"Or," T-Bone said, leaning against the wooden bulkheads, "he wants us to run out into thirty feet of open water right before a named storm tears the Gulf apart, so Vance doesn't have to deal with us filing an injunction in federal court."

"That’s a risk," Gage admitted.

The VHF radio on the dash hissed through a blanket of static, then cleared as the automated National Weather Service broadcast out of Mobile began its monotonous drone:

...Tropical Depression Four has been upgraded to Tropical Storm Mateo. Center located near latitude twenty-six point two north, longitude eighty-eight point five west. Movement north-northwest at twelve knots. Maximum sustained winds sixty-five miles per hour, with higher gusts. Rapid intensification is forecast over the next twenty-four to thirty-six hours as the system passes over the Loop Current. Small craft advisories are now in effect for all coastal waters from the mouth of the Mississippi River to Destin, Florida...

"Mateo," T-Bone spat. "Stupid name for a storm. Sounds like an insurance salesman."

"Sixty-five miles an hour," Gage said, his eyes fixed on the low-pressure needle. "By tonight, the swell will be running eight feet outside the barrier chains. The surf will start piling up against the shallow bars. That means the sand is going to move."

"And if the sand moves, whatever’s underneath it gets uncovered for about six hours before the current dumps another ten feet of silt on top of it," T-Bone finished the thought, his weathered hands tightening around the knife handle. "It’s a widow-maker window, Gage. You know that. We drop anchor in thirty feet of water with an eight-foot swell running, one broken chain link and the Restless ends up smashed across the sandspit like kindling."

"We don't drop anchor," Gage said, turning toward the wheel. "We run the side-scan sonar across the trench while the water is still clear enough to see through. We find the ballast pile before the storm hits the coast. Once the eye passes, the shelf will be ripped open. If we know where the stone is, we don't have to guess. We dive the minute the winds drop below gale force, while Vance is still waiting for the insurance assessors to clear his slip in Gulfport."

"He’s already got his permits," T-Bone noted sourly. "You know he’s got the state salvage commission in his pocket. He buys those regulators lunch at the yacht club twice a month."

"Admiralty law doesn't care about a state lunch," Gage said, shoving the single-lever bronze throttle forward.

The old Detroit Diesel sputtered, belched a small gray cloud of unburned fuel from the exhaust stack, and settled into a hard, vibrating roar that resonated through the floorboards. The Restless lifted her blunt bow, cutting through the green water as Gage swung the heavy wooden helm ten degrees to port, setting their heading southeast by south.

Out on the deck, the gulls that had been circling the menhaden bucket took flight, their high, shrill cries lost in the wind that was beginning to freshen from the east. It wasn't the lazy, damp breeze of an ordinary summer afternoon; it had a sharp, cool edge to it, like the draft coming off an opened meat locker.

The water around them was changing. The deep, bottle-green tint of the sound was turning a dull, bruised slate-gray, and the whitecaps were beginning to show irregular, jagged teeth. To the south, beyond the white-sand slivers of the barrier islands, the horizon was no longer a clean line. A thin, purplish haze had smudged the boundary between sky and sea, the outer veil of Mateo, reaching out hundreds of miles ahead of its center to test the coast.

Gage adjusted his throttle, feeling the vibration of the propeller shaft through the soles of his deck shoes. Every bolt in the hull was talking to him, the groans of timber and the slap of salt water against wood telling a story he had known since he was ten years old. The Gulf gave up its prizes only when it was angry, and it never gave them up for free.

He looked down at the brass compass in its binnacle, watch the needle steady on one hundred and forty degrees. Somewhere out there, beneath thirty feet of churning green surge, lay two centuries of rot, iron, and Spanish silver. And somewhere behind them, watching their wake, Nolan Vance was likely doing the exact same math—with bigger engines, deeper pockets, and fewer scruples about who came back up to the surface.

"Get the towfish out on the deck," Gage said over the diesel clatter. "Check the umbilical cable for cracks. If we lose the feed to the monitor, I'm not diving blind."

T-Bone didn't argue. He wiped his hands on his trousers, grabbed a grease gun from the tool rack, and went out into the freshening wind, leaving Gage alone with the clicking of the depth recorder and the steady, quiet descent of the glass.

The yellow fiberglass towfish was three feet long, weighed sixty pounds, and had twin stabilizing fins that gave it the sullen profile of a stunted hammerhead shark. It sat in a wooden cradle bolted to the Restless’s aft deck, tethered to a spool of steel-armored coaxial cable that had seen better days during the second Bush administration.

T-Bone was squatting over the cable head with an adjustable wrench and an unlit cigar jammed into the corner of his jaw. He smeared a thick gob of silicone dielectric grease across the multi-pin connector, his calloused thumbs working the gray paste deep into the rubber gasket.

"She’s corroded," T-Bone shouted toward the open wheelhouse door, competing with the thrum of the Detroit Diesel. "Number four pin has got green crust all over the copper. I scrape it, we get a signal for twenty minutes. We take a hard roll, water gets past the O-ring, and the monitor’s gonna show snow."

"Scrape it anyway," Gage called back. He kept one hand resting lightly on the spoke of the helm, his knuckles feeling the subtle vibration of the rudder stock. "Use the wire brush from the battery kit, then wrap the collar in vulcanizing tape. Two layers, pulled tight."

"Vulcanizing tape is five dollars a roll," T-Bone grunted, though he was already fishing the black roll from his hip pocket. "You're spending money like a man with two good kidneys and an inheritance."

"If we find what Finch was pointing at, I'll buy you a whole case of tape. You can wrap your boots in it."

Gage glanced up at the brass barometer again. The needle had crept another fraction of an inch to the left, crossing beneath 29.80 with the deliberate, indifferent slide of a butcher’s cleaver. The air inside the small wheelhouse had grown heavy, dense with moisture that didn't fall as rain but hung suspended, slicking the glass dials with a film of warm dew.

To the east, the low sandy shoulder of Petit Bois Island was slipping past two miles off the port beam. The island looked like nothing more than a pale brushstroke of bleached quartz sand and stunted scrub pine floating on a slate sea. On ordinary days, the sound side of the barrier was dotted with skiffs—weekend fishermen chasing speckled trout over the submerged grass beds, or families anchored in the shallows to drink beer from Styrofoam coolers. Today, the water was completely barren. The only other vessels in sight were two commercial shrimp trawlers four miles north, their long outrigger booms pinned tight against their deckhouses as they ran flat-out for the shelter of Bayou La Batre.

Those shrimpers knew the water better than any meteorologist with a degree from Florida State. When the fleet pulled its nets early, it meant the bottom was already getting restless.

Gage reached over and flipped the switch on the side-scan console. The unit was an old Klein dual-frequency machine that he’d bought surplus from an oceanographic research outfit in St. Petersburg after they’d upgraded to digital towed arrays. The cathode-ray tube flickered, hummed with a high-pitched whine that set his molars on edge, and finally painted a greenish raster line down the center of the display.

"How’s the winch looking?" Gage yelled.

T-Bone gave the yellow towfish a final kick to test the cradle lashings. "Hydraulics are holding ten gallons of fluid, give or take what leaks onto my shoes. Cable’s free on the drum. When do you want this canary in the coal mine?"

"As soon as we clear the western shoals," Gage said. "We drop off the bar into thirty-five feet. I want the fish cruising twelve feet off the bottom. If the swells start heaving us more than six feet, tell me. I don’t want to plow three thousand dollars worth of sonar into a sand hump."

"If you plow it, you dive for it," T-Bone said. He climbed the two steps up into the wheelhouse, leaning against the teak door jamb. He smelled of salt, kerosene, and the cheap chewing tobacco he favored when he wasn't smoking. "Vance is already out past the twelve-mile line, Gage. I saw his masthead disappearing south toward the deep blocks half an hour ago. If he was headed for the south side of Petit Bois, why'd he burn fuel running due south?"

"Because Vance has three different companies registered to his office in Metairie," Gage said, his eyes scanning the horizon where the open Gulf met the pass. "He runs one set of books for the banks, one set for the state salvage board, and one set for himself. He wants the port authority radar in Gulfport to log him heading for the offshore oil rigs. Once he’s twelve miles out, outside state territorial waters, he turns east, kills his AIS transponder, and skirts back inside behind the storm swell."

"A decoy run," T-Bone mused.

"An expensive decoy run. That aluminum boat burns eighty gallons an hour when he drops the hammers. He’s putting on a show for whoever might be listening to the harbormaster’s radio log. He wants everyone to think he’s running south to secure a dynamic-positioning tender before the blow hits."

"Which means Finch was telling the truth," T-Bone said, his voice dropping an octave. "The old man wouldn't throw a signal unless he was scared Vance was going to cut him out."

"Finch has been diving on other men's nickels for forty years," Gage said. "He knows how Vance operates. Vance pays a finder's fee on paper, then finds a flaw in the diver's contract the minute the artifacts hit the federal marshal's custody. If Finch wants his cut of the Santa Rosa, he needs competition on the water. He needs another boat dragging iron, making noise, filing parallel claims so Vance can't seal the docket under an ex parte admiralty order."

"He's using us as an anvil," T-Bone said bluntly.

"Better an anvil than a bystander," Gage replied. "At least the anvil gets to hit something."

The Restless cleared the shallow tongue of sand that jutted from the western point of Petit Bois. Instantly, the boat’s motion changed. Inside the sound, the waves had been short, choppy ripples stirred up by the morning wind. Now, as the hull stepped out into the open mouth of the Gulf, she met the long, heavy ocean rollers that were being pushed northward by the distant machinery of Tropical Storm Mateo.

The first swell caught the boat slightly broadside. The wooden hull rose with a slow, majestic groan of oak frames and cypress ribs, lifted four feet into the heavy air, hung there for a heartbeat with her screws churning white foam near the surface, and then settled into the wide trough with a resounding slap that sent a sheet of warm green spray across the wheelhouse windows.

The wipers kicked in, dragging worn rubber blades across the glass with a screech that made Gage wince. Through the cleared arcs, the horizon looked greasy and wild. The light had turned an unnatural, sulfurous yellow, the kind of sky that old-timers along the Mississippi coast used to call "hurricane milk."

"Alright," Gage said, pulling the throttle back until the engine settled into an easy, thudding lope at six knots. "Put her in the drink. Take her out forty feet of cable to start."

T-Bone nodded, stepped back out onto the rolling deck, and released the manual dog on the hydraulic drum. The steel spool hissed as the cable paid out, the yellow towfish swinging out over the stern gantry on its braided steel pennant before plunging into the froth of the wake. It vanished beneath the surface with a quick, yellow flash, cutting straight down through the green water like a diving bird.

Inside the cabin, the green screen of the Klein recorder came alive.

At first, the display showed only the acoustic reflection of the boat’s own wake—a ragged, foamy cloud at the very top of the trace. But as the fish reached its operating depth twelve feet above the seabed, the electronic paper began to burn a clean, detailed portrait of the ocean floor.

The bottom here was a flat, uniform desert of Mississippi mud and white shelf sand, depicted as a fine, pale gray texture on the screen. Every few seconds, the scrolling image was interrupted by the delicate, rib-like ridges of sand waves carved by the incoming tidal current. Here and there, a small depression showed up as a dark shadow—a crab burrow or an abandoned anchor scar from some forgotten crew boat.

"Cable’s out forty-two feet," T-Bone reported, stepping back into the wheelhouse and wiping spray from his graying whiskers. "Transducer’s reading clear. She ain't chattering yet."

"Keep your eyes on that aft spool," Gage said. "The current out here is running counter to the swell. It’s going to belly the cable. If the fish starts hunting from side to side, we’ll lose our horizontal resolution."

Gage held the wheel with both hands now, balancing his body against the increasing heave of the sea. The swells were regular, spaced about eight seconds apart, but their height was creeping up. Five feet now, occasionally six, the crests tumbling over in ragged curls of white foam that hissed as they swept past the hull. The Detroit Diesel worked hard, its pitch changing from a deep growl as the bow climbed the face of a wave to a muffled rattle as the boat slid down the back side.

For twenty minutes, they ran a straight track along the thirty-foot depth contour, heading east-southeast. The sonar trace remained monotonously clean. Sand, mud, the occasional lump of dead oyster shell washed out from the passes. Nothing that looked like ballast stone.

To an untrained eye, a wooden shipwreck simply disappeared once the worms and the waves finished with it. But a Spanish vessel of the eighteenth century wasn't just wood; it was an artificial mountain of stone. To keep a high-sided, top-heavy galleon or frigate from capsizing in Atlantic gales, the Spanish shipwrights loaded their lower holds with hundreds of tons of heavy river stones, granite cobbles, and basalt blocks gathered from the riverbanks of Spain and the Americas. When the wood rotted away, the ballast pile remained—a long, loaf-shaped mound of foreign rock that didn't belong on the silt-laden sandy bottom of the Gulf shelf.

Find the stones, and you found the ship.

"Nothing," T-Bone said, staring over Gage’s shoulder at the screen. "Just mud and more mud. Maybe Finch’s fingers meant three miles south. Or maybe he was just waving goodbye to your dumb ass."

"Finch didn't wave," Gage said, his eyes tracking the scrolling scan lines. "Look at the depth finder. The trench is pinching out. The bottom’s shoaling up toward the spit."

He nudged the helm five degrees to starboard, bringing the Restless slightly farther out into the open water. The swell caught them more directly on the bow now, throwing plumes of spray that reached as high as the cabin roof, rattling against the marine plywood like buckshot.

Then, right at the outer edge of the side-scan’s port channel, a smudge appeared.

It wasn't the soft, indistinct shadow of a sand dune. It was sharp, dark, and cast an acoustic shadow behind it that cut across the screen like an ink stroke.

"Hold on," Gage whispered, his hand freezing on the throttle lever.

He leaned close to the monitor, his breath fogging the corner of the cathode tube. The line of pixels painted another stroke, then another. The object wasn't large—perhaps eight feet long and two feet wide, lying at an angle across the ripple marks of the sand.

"That ain't stone," T-Bone said, squinting through the glare. "Too straight. Ballast doesn't lay in neat lines like that. Ballast looks like a sack of potatoes dumped out on a rug."

"It’s iron," Gage said. "Look at the return. The reflection is hard white, and the shadow behind it is dead black. High density."

"Pipe? Old drill casing?"

"Too thick for drill pipe. Look at the ends. It tapers at the cascabel." Gage’s voice was remarkably steady, but T-Bone could see the corded tendons standing out in his neck. "That’s an iron gun, Clarence. Six-pounder or nine-pounder. Lying right on the hardpan where the current scour washed the sand away."

T-Bone let out a low whistle through his teeth. "One gun don't make a wreck. Ships threw ordnance over the side all the time when they were running aground to lighten the draft."

"They didn't throw them into the deep trench," Gage said. "If they were running aground, they were heading for the shallows. This gun is in thirty-two feet of water. She didn't get jettisoned; she fell through the deck when the timber gave out."

Gage reached up and hit the event marker on the GPS plotter, dropping an electronic waypoint directly over the coordinates. The numbers glowed bright amber against the black background: 30°11.412' N, 88°31.805' W.

"Swing around," T-Bone urged, the lethargy completely gone from his voice now. "Make another pass fifty yards to the south. If there’s one tube, the rest of the battery has got to be within a cable’s length."

"I can't turn sharp with forty feet of wire out," Gage said. "I turn tight, the fish drops like a brick and hangs up on the bottom. We have to haul the gear, come about, and reset the line."

"Then let's haul it," T-Bone said, turning toward the door. "Before this wind turns around and blows our teeth down our throats."

He stepped out onto the open deck, reaching for the hydraulic control lever on the winch. But before his fingers could touch the valve handle, the Restless took a violent, shuddering lurch that wasn't caused by a wave.

The boat didn't roll; she was pulled.

The stern dipped three inches into the water, the wood around the towing gantry screaming under an instantaneous load that pulled the Detroit Diesel down three hundred RPM in a half-second flat. The engine belched a black plume of soot that whipped away into the rising gale.

"What the hell!" T-Bone barked, grabbing the iron rail to keep his feet as the deck tilted sharply beneath him. "Did we hang a ledge?"

"There are no ledges out here!" Gage shouted, dropping the throttle to neutral. "Get that drum dog off! Pay out cable! Pay it out before it rips the bitts out of the deck!"

T-Bone slammed his palm against the hydraulic release. The lever moved, but the drum didn't spin. The steel cable was bar-taut, vibrating like a bass guitar string, humming with a terrifying high-frequency whine that threw off a spray of pressurized saltwater from the strands. The yellow gantry frame, welded from two-inch schedule-forty structural steel pipe, was visibly bending forward toward the wheelhouse.

"The winch is jammed!" T-Bone yelled, his voice cracking against the wind. "The cable’s wedged between the drum flange and the housing! She’s dog-legged!"

Gage didn't hesitate. He reached behind the helm, grabbed the heavy red-handled fire axe mounted to the bulkhead, and kicked the wheelhouse door wide. The wind hit him like a wet blanket, ripping his cap from his head and tumbling it into the gray sea.

The Restless was being dragged backward. The current and whatever had caught their fish was pulling the stern down into the troughs. A five-foot roller broke over the transom, flooding the deck ankle-deep with foamy green brine that swirled around T-Bone’s knees before draining sluggishly through the freeing ports.

"Stand clear!" Gage roared, raising the axe above his shoulder.

Cutting an armored steel cable under twenty tons of static tension was an act of desperation. When the steel strands parted, the loose ends would whip back like a pair of high-speed machetes, capable of severing a man’s leg or decapitating anyone standing in the recoil path.

Gage braced his feet against the engine hatch coaming, his eyes fixed on the point where the cable entered the stern roller.

Before he could swing, the strain on the cable changed. It didn't snap. It didn't slacken slowly.

It began to jerk.

Three rhythmic, heavy pulses tugged at the stern—thump, thump, thump—each pull dragging the boat’s transom lower into the sea, until water was sloshing over the engine hatch. It wasn't the dead, mechanical hang-up of an anchor snagged on a bottom wreck. It felt deliberate, like something immense was taking up the slack by hand.

"Gage!" T-Bone screamed from the safety of the cabin corner. "Cut it! Cut the damn wire!"

Gage brought the axe down with everything he had.

The hardened steel blade struck the armored cable right against the brass lead of the fairlead roller. Sparks exploded in the gloom—bright, violent orange pinpricks that sizzled in the salt spray. Two outer strands of the steel armor parted with a loud ping, uncoiling like angry snakes, but the heavy core held fast.

The boat took another violent plunge, her stern submerging to the gunwales. A green wave washed straight over the engine hatch, the cold water hissing against the hot exhaust manifold beneath the deck plates with a cloud of white steam that smelled of scorched oil.

Gage raised the axe a second time, his muscles burning, his balance teetering on the slick, angled wood.

Through the clear green face of the wave that was currently sweeping over the stern, he saw something in the water thirty feet behind the boat.

It wasn't a log, and it wasn't the yellow towfish.

It was a black, cylindrical shape, nearly four feet in diameter, moving completely counter to the sea swells. It sat five feet below the surface, its presence betrayed only by the twin swirling eddies running off its blunt, hemispherical nose. For three seconds, it hovered in the prop wash of the Restless, a dark, unnatural shadow of riveted steel or molded composite that had no business existing in thirty feet of water off the Mississippi coast.

Attached to its upper hull was a heavy hydraulic clamp, its forged-steel jaws locked firmly around the armored cable of Gage’s sonar fish.

It wasn't a hang-up.

It was an intercept.

Gage’s second blow landed true. The axe bit into the partially severed core of the cable. With a sound like a rifle shot, the steel cable exploded.

The tension released instantly. The recoil whipped the severed boat-end of the wire upward, the frayed strands slicing through the wooden corner of the wheelhouse roof like a razor through cardboard, showering the deck with splinters of painted pine.

The Restless, freed from the anchor that was dragging her down, lunged forward as her bow dropped and her buoyancy asserted itself. The stern popped back up out of the sea, dumping hundreds of gallons of trapped water through the open scuppers in a roaring cascade.

Gage fell hard onto the wet deck plates, the axe skittering away from his grip and slamming against the starboard washboard. He lay there for a second, gasping for breath, the cold salt water soaking through his trousers and shirt.

Above him, T-Bone was already at the engine controls, throwing the Detroit into forward gear to keep the boat’s head to the rising seas before the next roller could catch them beam-on.

"You whole?" T-Bone barked down at him, his face as white as clean canvas.

Gage hauled himself up by the handrail, his breath coming in ragged hitches. His shoulder throbbed where he’d struck the hatch coaming, but his bones were intact. He didn't look at his bruised arm; he looked straight back over the stern.

The wake was empty. The dark shape beneath the water was gone, leaving only the frothing, irregular churn of the whitecaps and the slick trails of diesel foam.

"Did you see it?" Gage demanded, pulling himself into the wheelhouse.

"See what? I was looking at the water coming over the transom!" T-Bone shouted back, his hands white-knuckled on the wheel as he fought a six-foot sea that tried to broach them to port. "I thought we were going to the bottom, Gage! I thought the whole damn transom was coming off!"

"It wasn't a hang," Gage said, his voice dropping into a hard, cold register that cut through the engine noise. He reached over and touched the Klein sonar display. The screen was dead, showing only static lines where the severed coaxial cable had shorted out. "Somebody was waiting on that trench. They had a diver sled or an ROV down there."

"An ROV?" T-Bone looked at him like he’d lost his mind. "In thirty feet of water? In four-foot seas? Nobody runs an unmanned vehicle in the shoals, Gage. You'd smash the thrusters to pieces against the sandbars."

"A commercial unit wouldn't survive it," Gage said, his eyes scanning the southern horizon. "A survey unit off an oil patch support boat would."

He reached for the marine binoculars hanging from the center window strut, bracing his elbows against the console to steady the lenses against the violent heave of the boat. He swept the southern sector, looking past the whitecap ridges that were now building into continuous, gray-green rollers.

Ten miles out, barely visible through the darkening squall haze, was the silhouette of a vessel.

It wasn't Nolan Vance’s sleek blue Vanguard.

It was an offshore support vessel—a hundred and eighty feet of flat-nosed, black-hulled industrial iron with a massive yellow crane mounted on its aft deck and a high, vertical bow built to take the worst the Atlantic could throw at it. It was idling just outside the shipping channel, its position maintained not by anchors, but by the computerized thrusters of a dynamic-positioning system that held it steady to within six inches of its coordinates.

"The C-Triton," Gage muttered, lowering the glasses. "Vance didn't hire Finch to dive from his yacht. He leased an industrial platform from the Morgan City yards."

"That costs twenty thousand dollars a day," T-Bone said, his jaw slumping open. "Nobody spends that kind of paper on a hunch, Gage. Nobody."

"He didn't spend it on a hunch," Gage said, looking down at the chart where his lone pencil mark sat over thirty-two feet of water. "He already knows the ship is there. He’s known for months. What Finch gave us wasn't a tip-off to the gold."

"Then what the hell was it?"

"A tripwire," Gage said, his fingers tightening on the chart table edge until his knuckles turned ivory. "Vance needed to know if anyone else had the coordinates before the storm shut down the coast. If I stayed in the harbor, he knew he was the only one with the mark. But if I came straight out here, dropped a fish, and hit the trench..."

"He knew you had the scent," T-Bone finished, his voice hushed. "And he just cut our line so we couldn't pin it down."

"He didn't just cut the line," Gage said, pointing down through the salt-streaked windshield at the aft deck. "He tried to sink us. If that cable hadn't parted on the second blow, the stern would have stayed under when that third roller hit. We’d be sitting on the bottom with the Santa Rosa right now, and the Coast Guard report would have called it an accident caused by an amateur salvager caught out in a tropical depression."

T-Bone didn't answer. He turned his head slowly, looking out the side window toward the south.

The sky had lost its last trace of yellow. It was now a deep, bruised charcoal, almost purple at the horizon where the first rain bands of Tropical Storm Mateo were beginning to march across the open shelf. The wind had jumped another ten knots in the last fifteen minutes; the wire stays running to the Restless’s stubby radio mast were humming a mournful, single-tone note that vibrated through the timber of the roof.

The barometer on the bulkhead clicked. The brass needle settled into the hollow curve below 29.70 inches.

"We can't stay out here, Cap," T-Bone said quietly. "Not with forty-two feet of wood, a bent gantry, and five hundred gallons of seawater sloshing around in the bilge. If the bilge pump switch hangs up, that Detroit’s going to drown."

Gage didn't answer right away. He reached out and touched the red marker button on the GPS unit once more, making sure the coordinates were burned into the non-volatile memory of the old machine.

30°11.412' N.

He didn't need the towfish anymore. He knew what was down there. An iron nine-pounder, lying on a scour mark that shouldn't exist unless a two-hundred-ton hull was buried just upstream of the current, blocking the drift of the sand.

"Turn her around," Gage said, his voice flat and hard as cold pig iron. "Head for the pass. We run inside the sound and tuck into the bayou behind Pascagoula."

"And Vance?"

"Vance has to pull that ROV out of the water before the seas hit ten feet, or the crane will whip it against his hull and punch a hole in his engine room," Gage said, looking back one last time at the distant black silhouette of the C-Triton. "He can't work in a hurricane any more than we can. He’s got to run for the river mouth or take shelter behind Ship Island."

Gage picked up the fire axe from the deck outside, set it back into its bulkhead brackets, and clicked the brass retaining catch shut.

"He thinks he bought the bottom," Gage said, his hand resting on the smooth hickory handle. "He thinks sixty tons of steel and an admiralty lawyer give him the right to everything the Gulf covered up. But this storm isn't his, Clarence. It doesn't work for him."

The Restless swung her head around, her blunt wooden nose rising high against a charging gray roller before slicing through the crest with a heavy, shivering slam that threw salt spray thirty feet into the darkening air. With the following sea now pushing her stern, the old boat surged forward into the safety of the sound, racing the low, ragged clouds that were beginning to swallow the coast whole.
