Beyond the Reach of Oars

Chapter One: Milk-Brown Water

The strait had turned the colour of weak tea with milk in it, and it had been that colour for eleven years.

Tom Halgrave stood at the rail of the Kestrel Bay with a mug of coffee going cold in his hand and watched the dredging pontoons work. There were maybe two hundred of them within sight, scabbed together out of oil drums and bamboo and salvaged plywood, each one with a suction pipe going down into the seabed and a diesel engine hammering away on deck. They chewed the bottom for tin. What came up was ore. What went back over the side was everything else: sand, mud, shell, the pulverised remains of whatever had been living there. The water off Bangka's east coast had not been clear since before most of the pontoon crews were born.

"Visibility on the bottom," said Freddie Marlin from inside the wheelhouse, "is what I would describe as theoretical."

"How theoretical?"

"I can see the ROV's own lights reflecting off the murk. That's it. That's the whole show." A pause, the click of a joystick. "It's like flying a drone through soup. Chunky soup."

Tom came in out of the sun. The wheelhouse smelled of diesel, instant noodles, and the particular hot-plastic smell of electronics that had been running too long in the tropics. Freddie sat hunched over the control console with a headset pushed back off one ear, both thumbs working, her eyes fixed on a screen that showed almost nothing.

She was thirty-four, wiry, sunburnt in permanent stripes where her shirt collar sat, and she flew a remotely operated vehicle better than anyone Tom had ever met. He had seen her thread a two-tonne ROV through the collapsed superstructure of a ferry in a three-knot current without touching a single wire. She could not parallel park a car. He had watched her try.

"Where are we?" he asked.

"Kilometre eleven of the route. Which means we have eighty-nine kilometres left, at four kilometres a day, at a rate of pay that I want you to know I have calculated down to the hour, and it comes out at less than the girl who sells us fuel makes."

"The client pays in stages."

"The client pays late."

"He pays late," Tom agreed. "But he pays."

That was the whole of their business now, stated fairly. Three years ago Halgrave Marine Salvage had owned two vessels, a hyperbaric chamber, a crew of nine, and contracts booked eighteen months out. Then there had been a lift off Batam — a drilling module, four hundred tonnes, a shared job with a bigger outfit that had the crane barge and the political connections. A shackle failed. The module swung. A diver named Adam Chey, twenty-six years old, was in the water where he should not have been, because someone had cleared him down without checking the lift plan, and the load caught him against the leg of the jacket.

The inquiry had lasted five months. Kirke Marine — the bigger outfit — had brought four lawyers and a firm of forensic engineers. Tom had brought his logbook and an increasingly bewildered look. The finding, when it came, was worded with such careful vagueness that any reader could take from it what they liked, and every insurer and port authority in the region took from it that Tom Halgrave's company had killed a man. His underwriters cancelled. His bank called in the notes. Two of his crew testified, honestly, that they had heard him give the clear-to-dive over the radio, which he had not, because the radio log was gone and the deck supervisor that day had been Kirke's.

What was left of it all was the Kestrel Bay: a twenty-two-metre survey boat with a tired Cummins engine, an A-frame welded on by a man in Belawan who had done it for beer, a hire container of side-scan and ROV gear that Tom made payments on the way other men made payments on a house, and Freddie, who had refused to leave.

"Hold on," Freddie said.

Tom looked at the screen. Silt. Grey-brown static.

"Snag?"

"Something's got the port thruster guard." Her hands went very still, then began making small adjustments, feathering. "Not weed. Not net. It's solid."

"Cable?"

"There is no cable here. That's the entire point of us being here. We're mapping where the cable is going to go." She backed off, edged up, backed off. "Give me a metre of altitude and I'll clear the—"

The screen went from brown static to something with an edge in it.

It happened so fast that Tom nearly missed it: a curve, a long smooth curve of darker material, with the ROV's lights raking along it and picking out shadow in a line of round bumps. Then the silt rolled back in and it was gone.

"Stop," said Tom.

"Already stopped."

"Go back."

"Going back." Freddie's voice had lost all its complaint. She brought the vehicle round in a slow arc, waited a full minute for the cloud to settle, and eased in again with the lights low and angled.

The curve came back. It filled the bottom third of the screen: two metres of a smooth flank running away into the murk, and along it a raised line of knobs, evenly spaced, each about the size of a fist.

Tom put down his coffee.

"Is that a pipe?" Freddie asked.

"No."

"Is it a hull?"

"Yes."

"Steel hulls don't have—"

"It's not steel." Tom leaned in until his nose was almost at the screen. Under the ROV's lights the surface had a grain to it. Actual grain, wood grain, black and dense with age, and those knobs weren't fouling or fittings. They were lugs. Carved lugs, left standing proud from the inside of a plank when the rest of the plank was adzed away, drilled so the frames could be lashed to them with rope instead of nailed.

He had read about it. He had never seen one. Nobody had built a hull that way in a thousand years.

"Freddie," he said. "How much line do we have out?"

"Ninety metres. Depth's twenty-eight." She swallowed. "Tom, that's not — this thing is under the tailings. There's two metres of dredge spoil sitting on top of it and we've only got the edge because a suction head must have come past and cut a trench."

"Fly the trench."

She flew the trench. It took forty minutes, back and forth, the silt rolling and settling, rolling and settling. What emerged, in pieces, was a section of hull perhaps eleven metres long, lying with a list to starboard, the upper strakes eaten away but the lower ones sound because the mud had sealed them from the worms. Near the middle of it, half buried, the ROV's lights caught a shape that was too regular to be a rock: a low box with a domed lid, dark, bound at the corners.

"Is that—"

"Take a mark," Tom said. "Take a mark now, take three, get me the DGPS fix and a heading, and then bring her home."

"You're going to dive it."

"Yes."

"It's a hundred metres from an active pontoon field. Those suction heads run all night. If one of them comes across you they will hoover you up and never know it."

"Then I'll dive at slack water, when they shift." He was already going for the compressor. "Freddie. Look at me. I need you to understand that this changes everything, or nothing, and we won't know which for about six hours."

She looked at the frozen frame on the screen — the black curve, the row of lugs — and Tom saw the exact moment the caution went out of her face and something else came into it.

"I'll get the shot line," she said.

He went in at half past four, when the tide slackened and the nearest three pontoons cut their engines to change crews. Twenty-eight metres, on air, with a torch that lit maybe forty centimetres of water in front of his mask. It was less like diving than like crawling through a house with the lights off.

He found the shot line's weight sitting exactly where Freddie had put it, which was the best piece of driving he had seen all year, and he found the hull by touch. His glove went from soft ooze to something hard, and he ran his hand along it and felt the lugs come up under his palm, one, two, three, evenly spaced, each with the round mouth of a drilled hole in it.

A thousand years. He was touching a boat that had been built by men who lashed their ships together with palm-fibre rope, who had never seen an iron nail, whose empire had run this strait when Europe was still arguing about the alphabet.

He made himself work. He measured with his arm span, took photographs he knew would be useless, and moved along the flank until he came to the box.

It was teak, and it was heavy, and it was sheathed at the corners in metal that had gone chalky white. Lead. Someone had sealed this chest in lead and then dropped a ship on top of it.

He got a strop under one end, then the other. He clipped on the lift bag and gave it three short pulls of air from his octopus, and the bag ballooned and stood up in the dark, and the chest broke free of the mud with a slow sucking reluctance and began to rise.

Tom went up with it, one hand on the strop, watching his depth gauge and the bubbles and the dark, and when he came out into the last light of the day the pontoons had all started up again and the sea around him thudded like a drum being beaten by two hundred men who could not hear each other.

Freddie got a line on the bag before she got one on him.

They opened it on the after deck at nine that night, with the deck lights off and a head torch balanced on the winch drum, because Tom's instinct in every part of his life now was to be unobserved. The lead seam had cracked but held. Inside the teak was a second box, this one of some black resinous wood, and inside that, packed in what had once been cloth and was now a grey paste, were two objects.

The first was a sheet of gold.

It was about the size of a placemat, hammered thin enough to bend under its own weight, and covered edge to edge in small precise script. It was also torn — not ragged, but cut, sheared cleanly down the right-hand side so that half of every line on that side was missing.

The second was a boss of bronze the size of a dinner plate, dished, with a square socket in the middle where a shaft had once fitted, and around the rim a ring of small silver stars inlaid into the metal. Tom counted them without meaning to. Twenty-eight.

Freddie made a sound in her throat.

"That is," she said, "a great deal of gold."

"It's not the gold that matters." Tom turned the sheet gently in the torchlight. The script was nothing he could read, a flowing round hand, but in the bottom corner, stamped rather than written, was a small square with three lines of a different script entirely — angular, southern, nothing like the rest. "It's what it says."

"Do you know anyone who reads a thousand-year-old alphabet?"

"No," said Tom. "But I know someone who knows someone."

He stood there a long time with the sheet in his hands and the pontoons hammering away in the dark all around him, two hundred engines beating the water to soup, chewing up a seabed that had a thousand years of somebody's history in it, and he thought: whatever this is, it is not going to stay quiet for long.

He was right about that, and wrong about how long. It had thirty hours.
