The salt in the air at Trinity Bay had a way of turning brass green in under a week, which made the delicate maintenance of telegraph instruments an act of constant, scrubbing desperation. Arthur Finch sat at the long spruce bench of the Atlantic Telegraph Company’s western terminus, his thumb blackened with soot from the oil lamps and his fingertips raw from emery paper. Outside the cedar-shingled hut, the Atlantic Ocean pounded against the slate cliffs of Newfoundland with a rhythmic, heavy roar that vibrated straight through the floorboards and settled into the marrow of his shins.

It was August 5, 1858. Three days earlier, HMS Niagara had limped into the cove, trailing behind her the heavy, gutta-percha-coated tail of the transatlantic cable. The village of Heart’s Content, previously notable only for its cure of salted cod and its stubborn population of Gaelic-speaking fishermen, had suddenly become the ear of the Western Hemisphere. The cable lay coiled out from the surf like a drowned serpent, hauled up the shingle by two dozen sweating sailors and anchored into the floor of the test room through a brass-sleeved conduit that smelled strongly of pine tar and wet wool.

Finch adjusted the wick of his tin lamp and examined the mirror galvanometer on the table. The instrument was William Thomson’s masterpiece, a jewel of copper wire, tiny suspended mirrors, and silk fiber so fine it could barely be seen with the naked eye. When a current passed through the coils, the suspended magnet turned, deflecting a beam of lamplight across a graduated celluloid scale pinned to the far wall. It was an astonishingly sensitive contrivance. It was also, in Finch’s private opinion, a dreadful nuisance to keep steady when the wind blew through the clapboards hard enough to make the spittoon slide across the pine floor.

Across the bench sat Walter Callow, the company’s senior electrician, whose beard was trimmed with clerical precision and whose waistcoat pockets were perpetually full of dried ginger and spare battery carbons. Callow was nursing a cup of black tea that had gone cold an hour ago, his eyes fixed on the scale with the unblinking intensity of an osprey over a shallows.

"She is quiet tonight, Arthur," Callow murmured, tapping the brass key with the tip of an unlit pipe. "Too quiet for a wire running two thousand miles under the swell. Valentina should have sent the morning alignment pulses from the Irish end thirty minutes ago."

"The Valentia operators are likely asleep over their jars of sulfuric acid," Finch said, not looking up from his logbook. "Or Mr. Whitehouse is busy ramping up his induction coils again. If he puts another two thousand volts into the eastern end, he will bake the gutta-percha into brown bread before the week is out."

Callow made a soft, tutting noise. Edward Orange Wildman Whitehouse, the company’s chief medical-man-turned-electrician back in London, had a disastrous theory that massive electrical pressure was required to force a signal across the vast Atlantic basin. Thomson, the mathematician in Glasgow, had argued tirelessly for delicate, low-voltage currents and sensitive receivers, but Whitehouse held the ear of the board of directors. Between Whitehouse’s brute-force dynamos in Ireland and the merciless Atlantic deeps, Finch often wondered if the wire was carrying human thoughts or merely the agony of tortured copper.

Finch dipped his steel nib into the iron-gall ink and made the routine entry in the sheepskin-bound register:

05 August 1858. 03:14 GMT. Station Heart's Content. Ambient temperature 41 degrees Fahrenheit. Barometer 29.82 inches and falling. Line to Valentia grounded via sea-earth plate. Earth currents moderate, fluctuating between three and seven degrees positive. Thomson needle steady at zero mark.

He set the pen down and leaned back, stretching his shoulders until his spine clicked. Through the narrow, salt-filmed window, he could see the gray light of a northern dawn creeping over the hills. A solitary dory was already out in the bay, its oars rising and falling in the mist like the legs of a water-strider. For all the modern majesty of instantaneous communication, the station remained a frontier outpost, isolated by hundreds of leagues of spruce forest and bog from the railheads of Halifax and Boston. If the wire died, they were simply men sitting in a wooden box on a wet rock.

A sudden, sharp flick of light caught the corner of his eye.

The reflection from the mirror galvanometer did not drift in the slow, wandering manner characteristic of Newfoundland’s terrestrial magnetism. It snapped. It leapt six divisions to the left, hung suspended for a fraction of a second, and then jumped back to the center before twitching three times to the right.

Callow’s tea cup remained halfway to his mouth, suspended in mid-air. "Did you see that?"

"I saw it," Finch said, rising from his stool so quickly he nearly tipped the inkwell. He caught it with his palm, smearing his cuff with fresh black. "Was that Valentia?"

"The key was locked out," Callow said, his voice dropping an octave as he reached across the table to inspect the brass commutator switch. "The line was thrown to the sea-earth plate. We were isolated from the main battery bank."

Finch felt the skin on the back of his neck prickle. A disconnected line should have registered nothing more than the dull, rolling murmur of the earth’s own electrical heartbeat—the slow slosh of the magnetic tide that drifted with the sun and the aurora. It could not, by any known law of galvanic physics, produce a sharp, deliberate deflection.

"Check the ground plate," Finch said. "Perhaps the surge from the surf—"

"The ground plate is forty feet down in the silt of the cove, weighed with three tons of pig iron," Callow snapped, his fingers already flying over the brass thumb-screws of the test set. "Look at the scale, man! Don't stare at me, look at the scale!"

The tiny spot of yellow lamplight was dancing again. It was not the erratic jitter of lightning discharge from some distant mid-ocean storm. It had a cadence. It struck the celluloid strip with measured, rhythmic precision: two beats short, one long, followed by an interval of absolute stillness that lasted precisely four seconds. Then it began again.

Finch pulled the cipher pad toward him, grabbed a dry pencil, and began to slash marks against the ruled lines.

Dot. Dot. Dash.

Dot. Dot. Dash.

Dot. Dash. Dot. Dot.

The rhythm was fast—far faster than any human operator could manage through two thousand miles of submerged, inductive cable. Due to the electrostatic retardation of the line, a signal sent from Ireland took more than a second to smear its way through the copper core and emerge as a sluggish, teardrop-shaped impulse in Newfoundland. It was like shouting down a lead pipe stuffed with wet sheep’s wool; one had to speak slowly, spacing every letter by several heartbeats, or the words blurred into an illegible smear of current.

Yet these impulses were crisp. They struck the mirror with the sharp, clean crack of an overhead wire strung between telegraph poles along the Great Western Railway in England.

"It’s impossible," Finch muttered under his breath, his pencil flying across the cheap paper. "The retardation factor alone should flatten pulses of that duration into a dead plateau. Nothing that sharp can come through two thousand nautical miles of gutta-percha."

"Then it isn't coming from Valentia," Callow whispered. He had stood up from his chair, his hands resting flat on the oilcloth covering the test bench, leaning forward as if he could look straight through the brass casing of the galvanometer into the Atlantic abyss. "Throw the shunt. Cut the sea-earth."

Finch threw the heavy porcelain-handled switch. The contact broke with a tiny, dry click. The Heart’s Content station was now entirely severed from the subsea cable; the terminal was an open circuit, disconnected from the earth and from the ocean, floating free in the electrical continuum.

The spot of light on the scale should have dropped instantly to dead zero and stayed there.

It did not.

The spot of light flared bright, snapped ten degrees to the right, and resumed its rapid, mechanical chatter.

Finch stopped writing. He stared at the brass terminals. The copper lead coming in from the cable trench was severed by a three-inch air gap at the switch. The ground lead lay curled on the pine floorboards like a dead worm. The instrument was connected to nothing at all save for a two-foot length of silk-insulated wire running between the galvanometer coils and a dead zinc plate sitting on the shelf behind the stove.

The air in the room seemed suddenly to thin, smelling not of tea or lamp oil, but of ozone—the sharp, metallic tang that lingers after a lightning strike on a granite tor.

"Callow," Finch said softly. "Where is the current coming from?"

Callow did not answer. He slowly reached out one trembling finger and touched the brass frame of the mirror galvanometer. The moment his skin made contact with the metal, a tiny, blue-white spark, no larger than the head of a pin, snapped between his knuckle and the thumb-screw. He jerked his hand back with an oath, sucking at his skin.

"The air," Callow said, his voice shaking with a strange mixture of awe and terror. "The charge is in the air of the room."

"There are no clouds above the cove," Finch said, glancing toward the salt-filmed window. The dawn sky was pale gray, clear and cold, with the morning star still gleaming brightly over the eastern headland. "There is no storm within fifty leagues."

On the wall, the spot of light continued its frantic, orderly dance across the marked divisions, casting its jittery yellow reflection into the dim corners of the station hut. Finch looked down at the pad of paper beneath his hand. The pencil marks were dark and uneven, pressed so hard into the wood-pulp sheet that the lead had snapped twice, leaving small gray gouges in the margin.

He looked at the sequence of characters he had recorded. They were not standard Morse, nor were they the Bain chemical code, nor the Cooke and Wheatstone five-needle cipher used by the British railways. They were arranged in rigid clusters of five, separated by uniform pauses, looking less like a message than a column of mathematical coordinates.

The light gave three final, violent lunges toward the maximum limit of the scale, quivered like a dying moth, and then drifted slowly, gracefully, back to the black zero mark in the center of the celluloid strip.

Silence returned to the hut, save for the kettle beginning to whistle its low, dry complaint upon the cast-iron stove.

Finch and Callow stood motionless on opposite sides of the spruce bench, looking at the dead instrument and then at each other. Neither man reached for the tea, and neither man spoke of Valentia. On the desk, the cipher sheet lay between them, the fresh lead marks catching the cold, gray light of the Newfoundland dawn like polished iron.

The smell of scorched gutta-percha lingered in the rafters of the instrument room like the ghost of an ill-tempered hearth. Walter Callow sat on a low three-legged stool, his gold-rimmed spectacles pushed up onto his forehead, using a pair of Swiss watchmaker’s tweezers to extract a minute flake of soot from the suspension chamber of the mirror galvanometer. His breath came in short, wheezing puffs that smelled faintly of the ginger root he chewed to ward off the dampness of the Newfoundland fogs.

Finch stood by the cedar-shingled wall, his hands buried deep in his waistcoat pockets, watching the gray rain beat against the small paned window. The morning had brought no clarity, only a dull, leaden sky that seemed to press down upon the dark waters of Trinity Bay like a damp wool blanket. On the spruce bench, the scrap of paper containing the five-character clusters lay held down by a brass weight. It looked harmless enough in the gray light, but to Finch, the dark pencil strokes had the cold, unsettling look of an epitaph written in an unknown tongue.

"The suspension thread is intact," Callow muttered, his voice flat with the professional stubbornness of a man who refused to allow the laws of physics to be insulted in his presence. "The silk is finest Chinese orange, boiled in boiled linseed oil to prevent hygroscopic twitching. There is no grease, no spider-webbing, no physical obstruction within the casing. If the needle moved, Arthur, it moved because a current passed through the coils. There is no other path for the mind to take."

"And the spark that bit your knuckle?" Finch asked, turning from the window. "Was that a phantom of the silk?"

Callow grunted, lowering his spectacles back over his eyes with a snap. "An accumulation of static from the wool carpet, most likely. Or a return path from the battery room through the damp pine flooring. The air in these northern latitudes is notoriously dry when the wind shifts to the northwest, even with the rain. We are sitting on a shelf of ironstone and wet bog, Arthur. We are essentially living inside a Leyden jar."

"A Leyden jar does not write in five-letter ciphers," Finch said, stepping to the bench and tapping the paper with his fingernail. "A Leyden jar does not maintain a cadence of seventy letters a minute with three-millisecond intervals between groups. I have spent five years on the London and Northwestern lines, Walter. I know the difference between the rattle of a loose lightning-arrester and the work of an operator's hand."

"Then who was the operator?" Callow demanded, his voice rising slightly as he set the tweezers down with a sharp clink. "The Agamemnon is steam-cleaning her boilers in mid-ocean, three hundred miles east of Cape Race. The Niagara is anchored in the cove outside, her cable end secured to our own terminal board. The Valentia station is two thousand miles away, and their operators are still trying to find why their signal-to-noise ratio is like whispering into a gale. There is no other wire, Arthur. There is no other station on this side of the water."

"Then we must assume the drift," Finch said quietly.

The "galvanic drift" was a term coined by the telegraph engineers of the decade to describe the mysterious, unwanted currents that crept into long submarine lines from the earth itself. It was well known that the globe was a vast, rotating dynamo, its crust laced with currents of electricity that flowed from east to west, carrying the magnetic tide along with them. During the great solar disturbances of the previous winter, the land lines across Canada had run for three days without a single cell of battery power, driven entirely by the furious, green-hued currents of the northern lights that danced above the spruce forests.

But the drift was always slow. It was a lazy, shifting tide that pushed the galvanometer needle to one side of the scale and held it there for hours, like a river current pressing against the rudder of a barge. It did not snap. It did not form clusters.

Finch reached for the logbook, flipping back through the pages of the previous autumn when the company had been laying the short-lived 1857 cable. He stopped at a page dated September 14, written in the neat, sloping hand of the surveyor who had preceded them at the Heart’s Content station.

"Look here," Finch said, tilting the book toward the dim window light. "September last. The HMS Cyclops was taking soundings off the Trinity shelf, fifty miles out. The log notes that the deep-sea thermometer registered a sudden, unexplained drop of six degrees Fahrenheit in the space of three cable-lengths. At the same hour, the land line to St. John’s experienced three hours of what the writer calls 'rhythmic twitching.' He attributed it to the friction of the Gulf Stream against the cold Labrador current."

"Friction does not generate five-letter code groups," Callow said, though he leaned forward to squint at the entry. "The surveyor was a hydrographer, not an electrician. He probably saw a loose connection on his terminal board and blamed the ocean to save his own credit with the directors."

"Perhaps," Finch said. "But the dates align with the great magnetic storms of that year. If the earth’s crust is under some manner of tension—some galvanic strain that we do not yet comprehend—might it not discharge itself in a series of rapid, oscillatory bursts?"

"You are speaking of wireless induction through fifty miles of saltwater," Callow said, shaking his head with a patronizing sigh. "It is the dream of the spiritualists, Arthur. Like those tables in Rochester that rap out messages from the dead. Next you will be telling me that the Atlantic cable is acting as a giant ear, listening to the thoughts of the codfish."

Finch did not laugh. He picked up the cipher sheet and held it near his lamp, studying the dark graphite lines. The five-character groups were arranged with an eerie, mathematical symmetry that did not suggest the wild, random forces of nature:

H R N T X K L M P Q X Z R T W O P L K M

"It is not Morse," Finch said, more to himself than to Callow. "The letters are too varied. In Morse, the frequent letters—the Es and Ts—are represented by single elements to save time. Here, the letters are distributed with absolute uniformity. It is a cipher based on a five-by-five grid, or perhaps a Wheatstone dial system. But look at the speed. Even if an operator had a master-key on a drum, he could not rotate the commutator fast enough to send these pulses through a high-induction line without them blurring into a single, continuous smear of current."

"Which brings us back to the apparatus," Callow said, rising from his stool and stretching his short legs. "The instrument must have run wild. A loose spring in the battery commutator, or perhaps a carbon deposit in the reversing switch. Let us go down to the battery cellar and see if the cells are gassing."

The battery room of the Heart's Content station was located beneath the main instrument room, reached by a steep, narrow flight of spruce steps that smelled perpetually of rotten eggs and wet lime. It was a cold, dark vault, its walls lined with shelves of rough-sawn pine that groaned under the weight of three hundred Daniel cells. Each cell consisted of a heavy glass jar filled with a saturated solution of copper sulfate, inside of which sat a zinc plate immersed in dilute sulfuric acid, separated by a porous earthenware pot.

Finch held the lantern high, its yellow light casting long, dancing shadows across the rows of jars. The blue copper solution gleamed like liquid sapphire in the gloom. A faint, steady hissing filled the air—the sound of thousands of tiny hydrogen bubbles rising from the zinc plates and popping at the surface of the acid.

"The cells are quiet," Finch observed, walking down the central aisle. "The liquid is clear. If we had suffered a massive discharge or a short-circuit during the night, the copper would have precipitated out as a black sludge on the bottom of the jars. The zincs are clean."

Callow knelt by the main terminal board at the end of the room, where the heavy copper leads from the battery banks were secured to brass bus-bars mounted on dry slate. "No sign of arcing here. The insulation is dry. The paraffin coating on the leads is intact." He reached out and touched the main knife-switch that connected the batteries to the instrument room above. "And the switch was open, Arthur. I opened it myself at midnight to prevent any leakage from the local cells into the line during the alignment test."

"So the local batteries were entirely out of the circuit," Finch said.

"Entirely. The only potential on the instrument was the residual charge of the cable itself."

Finch walked to the far corner of the cellar, where the heavy, gutta-percha-insulated core of the transatlantic cable entered through a thick iron pipe from the beach. The pipe was flanged and bolted to the stone foundation, sealed with a mixture of pitch and oakum to keep out the tide. The cable itself emerged from the seal like a greasy, black rope, its outer sheathing of iron wire rusted to a dull red-brown by the salt air.

He placed his hand on the cold iron of the pipe. He could feel the faint, rhythmic throb of the surf outside—the heavy, low-frequency vibration of the Atlantic swell breaking against the shingle fifty yards away. It was a physical sensation, a mechanical shudder that seemed to travel up through his arm and settle in his chest.

"Walter," he said softly.

"Yes?" Callow was still checking the connections on the slate board with his screwdriver.

"How deep is the cable trench in the cove?"

"Six feet," Callow said. "Lined with sand and covered with three feet of heavy split stone to keep the dories from catching it with their anchors. Why?"

"And the ground plate? The sea-earth?"

"The sea-earth is a sheet of copper, four feet square and an eighth of an inch thick," Callow said, his voice echoing slightly in the damp cellar. "It is bolted to three tons of old railway iron and sunk in the deep channel of the river mouth, well clear of the weeds. It is as solid a ground as can be found in the Western Hemisphere."

Finch knelt down by the entry pipe. A small trickle of rusty water was dripping from the oakum seal, forming a orange-colored pool on the concrete floor. He dipped his finger into the pool and touched it to his tongue. It was salt—bitter and cold.

"The seal is leaking," he said.

"It always leaks when the tide is high," Callow said, not looking up. "The pressure of the sea at forty feet is more than a bit of tarred rope can stand. It is nothing to worry about, Arthur. The copper core is protected by three layers of gutta-percha and two of tarred hemp. A bit of wet iron on the sheathing only improves the earth connection."

Finch didn't answer. He was looking at the copper lead that branched off from the main cable core just before it entered the terminal box. This was the "sea-earth" wire—the return path that connected the outer iron sheathing of the cable to the ground plate in the bay, completing the circuit through the ocean.

The wire was a thick strand of copper, insulated with a red gutta-percha sleeve. At some point during the installation, a heavy tool—perhaps a spade or a crowbar—had struck the lead, stripping away a three-inch section of the red insulation to expose the bright, pinkish metal beneath.

The exposed copper was not green with verdigris, as it should have been in this damp, salty atmosphere. It was bright and polished, as if it had been rubbed with emery paper only minutes before.

Finch reached out to touch the bare spot, but stopped his hand an inch away.

The air around the exposed copper was warm.

It was not the heat of a fire or a stove. It was a dense, localized warmth that felt like standing near a brick wall that had been baking in the August sun all afternoon. The rusty water dripping from the oakum seal above did not run down the wire; it seemed to avoid the bare copper, curling away in tiny, bead-like droplets as if repelled by some invisible force.

"Walter," Finch said, his voice dropping to a whisper. "Bring the lantern here."

Callow grumbled, but set his tools down and shambled across the damp floor, the tin lantern swinging from his hand. He knelt beside Finch, the yellow light illuminating the small, wet corner of the cellar.

"Look at the ground lead," Finch said, pointing.

Callow squinted through his spectacles, leaning close enough that his beard brushed the rusty iron pipe. "Well? It is a nick in the gutta-percha. The installers were careless wretches from the start. I have told the London board a dozen times that we cannot expect good work from sailors who—"

He stopped.

The small pool of rusty water on the floor beneath the wire was beginning to move. It was not draining away; it was swirling in a slow, clockwise circle, the tiny flecks of rust and silt forming a miniature whirlpool that spun around the point directly beneath the exposed copper lead.

"The tide must be rising through the floor," Callow said, though his voice had lost its confident, dry edge.

"The tide is falling," Finch said. "The high water was at five o'clock. And look at the water, Walter. It isn't rising. It is being pulled."

He took a small brass sewing needle from his waistcoat pocket—an instrument he used for clearing the ink-tubes of the recording instruments—and held it suspended from a six-inch length of silk thread over the swirling pool.

The needle did not hang straight down. The moment it came within three inches of the exposed wire, it swung sharply to the horizontal, its point aligning itself not with the magnetic north, but with the length of the copper lead. As Finch moved the thread closer, the needle began to spin, slowly at first, then faster and faster until it was nothing but a brass blur in the lantern light.

The silk thread began to hum. It was a high, thin sound, like the wing-beat of a midge.

"It is a solenoid," Callow whispered, his eyes wide behind his spectacles. "The ground wire is carrying a massive current. But how? The main battery is open. The Valentia line is quiet."

"The current isn't coming from our battery," Finch said. "And it isn't coming from Ireland."

"Then where?"

"From the sea," Finch said, looking toward the dark iron pipe that ran out into the black waters of the bay. "Something out there is using our earth plate as a return path. Something with a voltage that makes our three hundred Daniel cells look like a child's toy."

He rose to his feet, his heart hammering against his ribs with a sudden, wild energy. The cold dampness of the cellar seemed to have vanished, replaced by that strange, dry warmth that smelled of hot oil and wet stone.

"We must report this to the superintendent," Callow said, his voice shaking as he stood up and brushed the damp coal-dust from his knees. "Mr. Saward must be informed. He will want to notify the directors in London by the first mail steamer."

"And tell them what?" Finch asked, turning to face him. "That we have found a ghost in the cellar? That the Atlantic Ocean is sending us telegraph messages in five-by-five ciphers? They will replace us with two boys from the electric school in Hammersmith before the week is out. They have three million pounds of capital staked on this wire, Walter. They do not want mysteries. They want dividends."

Callow looked at the spinning needle, which was still humming its thin, dry song in the lantern light. "We cannot keep this silent, Arthur. If the current surges again, it will burn the coils out of the Thomson galvanometer. It will destroy the only sensitive receiver we have on this side of the ocean."

"Then we must protect the instrument," Finch said. "But we must also listen."

"Listen to what?"

"To whatever is out there," Finch said, his eyes fixed on the dark iron pipe. "The signal was too clean to be an accident of nature. It was sent, Walter. It was sent by someone who knows how to use the ocean as a wire. And if they are sending, they are waiting for an answer."

They climbed the narrow stairs back to the instrument room in silence, the lantern light flickering against the rough-hewn pine walls. The rain had stopped, but the fog was rolling in from the bay, thick and white as sheep's wool, swallowing the masts of the HMS Niagara where she lay at anchor in the cove.

Through the window, Finch could see the dull yellow glow of the ship's riding lights, looking like faint, watery stars in the mist. Beyond them, the vast, gray empty expanse of the Atlantic stretched away into the northern darkness—three thousand miles of cold, black water that had suddenly become very small, and very crowded.

Finch sat down at the spruce bench and pulled the cipher sheet toward him. He took up his pencil and began to write, his hand steady now, his mind focused with the sharp, cold clarity of a surveyor mapping a new and dangerous country.

"If it is a five-by-five grid," he said aloud, "then the letters are pairs of coordinates. One through five on the vertical, one through five on the horizontal. The oldest method in the world. The Greeks used it with torches on the walls of Troy."

"And what is the key?" Callow asked, sitting on the corner of the table, his unlit pipe held between his teeth.

"The key is always the same when men are in a hurry," Finch said. "It is the name of the place, or the name of the ship, or the name of the king."

He wrote the word VALENTIA in large block letters at the top of the page. He began to arrange the alphabet into a twenty-five-letter grid beneath it, omitting the letter J as was the custom in telegraphic codes.

He took the first five-character group from the cipher sheet: H R N T X.

Using his pencil, he located the coordinates for each letter on his grid, tracing the intersections of the rows and columns with his finger.

"H is row three, column three," he murmured. "R is row four, column four. N is row one, column five. T is row two, column one. X is row five, column three."

He wrote down the resulting numbers: 33 44 15 21 53.

He looked at the numbers. They meant nothing by themselves—simply a sequence of digits that might have been the soundings of a sandbar or the weights of coal bags. But then he looked at the second group: K L M P Q.

Using the same grid, he translated the characters into their numerical equivalents: 34 13 35 42 43.

He placed the two sets of numbers side by side on the paper:

33 44 15 21 53
34 13 35 42 43

He stared at the page for a long time, the pencil held idle between his fingers. The silence in the room was absolute now, save for the steady, rhythmic drip of the condensation from the eaves outside the window.

"It isn't a message," Callow said, leaning over his shoulder. "It is simply a list of numbers. Perhaps it is a calibration run for the eastern station's terminal board."

"No," Finch said, his voice dropping to a whisper. "Look at the first digits of each pair, Walter. Three, four, one, two, five. Three, one, three, four, four. They are not random. They are the degrees of latitude and longitude."

He rose from his stool and walked to the wall where a large, hand-colored chart of the North Atlantic was pinned to the pine boards. The chart showed the line of the submarine cable as a thin, red thread stretching from Valentia Bay in Ireland to Heart's Content in Newfoundland, crossing the vast, blue-tinted depths of the telegraphic plateau.

He found the coordinates on the chart's scale.

"Fifty-two degrees, forty minutes North," he said, his finger tracing a line across the blue paper. "Twenty-one degrees, fifteen minutes West."

He stopped. His finger was resting on a spot in the mid-Atlantic, hundreds of miles from any land, where the depth was marked as twenty-four hundred fathoms—a cold, dark abyss where the light of the sun had never reached, and where the pressure of the sea was enough to crush a hollow iron sphere like an eggshell.

"There is nothing there," Callow said, his voice dry. "Nothing but silt and water."

"And the cable," Finch said.

"The cable does not run through those coordinates, Arthur. We laid it three miles to the south to avoid the volcanic shelf."

"Then what is at fifty-two forty North, twenty-one fifteen West?"

Finch did not answer. He looked out the window at the white wall of the fog, which had now closed in completely around the station, blotting out the ship's lights, the hills, and the sea, leaving them alone in the dark, silent center of a world that was no longer theirs.
