The fog along the Thames smelled of coal smoke and rotting river cabbage, a thick, yellow broth that clung to Arthur Finch’s wool collar as he turned into the courtyard behind St. Mark’s Church. It was November of 1897, and London was settling into its usual winter damp, the sort of weather that made joints ache and copper wire tarnish before it could even be wound onto a bobbin.

Arthur adjusted his grip on the leather Gladstone bag. Inside, nestled among changes of linen and three spare pairs of wool stockings, sat two glass-walled coherers packed in sawdust, their silver-and-nickel filings carefully dried under an oil lamp only three hours earlier. In his coat pocket was an embossed letter from the Wireless Telegraph and Signal Company, signed in a brisk, forward-leaning hand by Guglielmo Marconi himself.

The workshop at Hall Street in Chelmsford was still half-built, so the company’s administrative heart beat in a drafty set of rooms near the Strand. When Arthur climbed the creaking stairwell to the second floor, he found the boy genius of Italian electricity pacing the bare boards. Marconi was barely twenty-three, five years younger than Arthur, but he moved with the unyielding gravity of an old general. His dark double-breasted suit was impeccably brushed, though smelling faintly of sulphuric acid from the rows of bichromate cells lined up along the skirting board.

"Finch," Marconi said, barely looking up from a diagram drawn across three sheets of blue drafting paper. "You are late. The tide on the river does not wait, and neither does the steam packet from Southampton."

"The omnibus shed an iron rim on Fleet Street, sir," Arthur said, setting down the bag with exaggerated gentleness. "The horse was not injured, but the driver’s vocabulary was considerably enlarged."

Marconi allowed himself a microscopic twitch of the lip—the closest he ever came to a grin during business hours—before tapping the diagram with the blunt end of a pencil. "Mr. Preece and his postal clerks are still muttering about induction through the earth. Let them dig their trenches. We are going into the salt air. The Isle of Wight station is already speaking across fourteen miles of water to the tugboat Solent. But that is mere child’s play. Fresh water and shallow straits are gentle mistresses. The real test is heat, humidity, and distance."

"And salt," Arthur added, unbuttoning his damp overcoat. "Salt will rot the brass terminals in a fortnight if we do not lacquer them."

"Then lacquer them twice," Marconi replied. He walked over to a pine crate that sat open near the window. Inside, nestled in oiled straw, lay an induction coil wound with nearly ten miles of silk-covered wire, its mahogany base gleaming like an expensive dining room sideboard. "The Spanish-American Cable Company has grown nervous. Or rather, the merchants who pay them have grown nervous. The undersea cables into the Caribbean are old, their gutta-percha insulation is cracking under the sea floor, and repairs cost thousands of pounds per nautical league. Furthermore, the political situation in the islands is... fluid."

"Fluid is an elegant word for an insurrection, sir."

"I am an electrician, Finch, not an ambassador," Marconi said coolly. "The London board has agreed to a demonstration. A commercial link between the southern coast of Cuba and the British relay station in Jamaica. If we can punch sixty miles through tropical air, the Admiralty will have to stop pretending we are a carnival trick. You are going to establish the station at Santiago."

Arthur looked at the induction coil, then at the crates of zinc plates and carboys of acid waiting by the door. His father had been a clockmaker in Clerkenwell, a man who believed that anything worth doing was held together by escapements, pinions, and balance wheels. To Arthur, who had spent four years studying physics under Silvanus Thompson at Finsbury Technical College before joining Marconi’s small band of believers, the invisible ripples in the ether still seemed half-miraculous, half-monstrous. They were not mechanical. You could not see the teeth catch. You simply created an electric violence at one point, and if you were clever and patient enough, a tiny spark jumped across the world at another.

"Why me?" Arthur asked. "Kemp has more experience with the spark gaps, and Paget understands the rigging better than anyone."

"Kemp cannot speak three words of Spanish without sounding like he is ordering a horse whipped," Marconi said, picking up a brass Morse key and testing its spring with his thumb. Click-clack. Click-clack. "You lived in Madrid as a boy when your father was repairing the clocks at the Royal Palace. Your Spanish is fluent enough to keep customs officials from impounding the batteries as munitions. Besides, Paget gets sea-sick in a bath-tub, and you spent two years on a cable-laying steamer in the North Sea. You know how to climb a mast in a gale without dropping the pliers."

"The Caribbean is rather warmer than the Dogger Bank," Arthur remarked.

"All the better for the filings in the coherer," said Marconi, handing him a brass-bound logbook with ruled blue lines. "No damp Thames mist to make them stick together. You sail tomorrow aboard the Royal Mail steamship Don. You will clear through Kingston, take a coaster to Santiago de Cuba, and meet a Mr. Walter Ramsden. He is the British consul there. A sensible man who has lived among the Spaniards long enough to know when to grease an official palm and when to mention Her Majesty’s gunboats."

Arthur ran his hand over the polished mahogany of the shipping crate. "And what am I to tell the local authorities regarding what these boxes contain?"

"Scientific apparatus for meteorological research," Marconi said without batting an eye. "It is not even a lie. We are measuring the electrical potential of the atmosphere. If we happen to be disturbing that potential with forty thousand volts of artificial lightning, that is purely incidental. Your papers describe you as an assistant engineer in the employ of the West India and Panama Telegraph Company, on loan for experimental wireless signaling."

"And if the Spanish officers suspect the equipment is for the insurgents?"

"The insurgents are hiding in the mountains with rusted machetes and empty bellies, Finch. They do not possess ten-inch induction coils or banks of Leyden jars. Show the officers the brass fittings. Show them the royal coats of arms stamped on the batteries. Spaniards respect bureaucracy almost as much as they respect the Church. If all else fails, buy the garrison commander a case of decent amontillado."

The meeting ended as all meetings with Marconi ended: abruptly, with the young inventor already turning his mind to the next problem, his pencil flying over another sheet of paper before Arthur had even picked up his coat. Arthur walked down the stairs into the cold afternoon, the weight of the brass key still distinct in his pocket.

The journey south from London began with the low, mournful hoot of the Don’s whistle as she backed out of Southampton docks into the gray chop of the Solent. For three days, the Bay of Biscay treated the ship with its usual ferocious indifference, tossing the two-thousand-ton iron hull like a wood chip, sending passengers scurrying to their berths and reducing Arthur’s world to the smell of damp mahogany, vomit, and coal gas. But Arthur stayed on his feet, checking the lashing on the six heavy packing cases in the hold every four hours.

Down in the ship’s belly, amidst the reek of bilge water and wet sacking, he inspected each crate with a lantern. The primary danger was the acid carboys; if the stoneware jars cracked, the sulfuric acid would eat through the timber framing and find the ships’ plates before morning. He stuffed extra horsehair around the necks of the jars, wedged wedges of soft pine under the corners of the battery boxes, and checked the seals on the coherer tubes.

By the fifth day, the Atlantic ceased its gray fury and softened into long, deep-blue swells. The heavy wool coats were packed away, replaced by linen jackets and broad-brimmed straw hats bought from a shipboard merchant who smelled of bay rum.

Arthur spent the afternoons on the forward deck, leaning against the teak railing and watching the flying fish scatter before the iron bow. Beside him stood an American named Cyrus Vance, a representative for a Philadelphia locomotive manufacturer who had spent three weeks trying to convince everyone aboard that the nineteenth century was about to be concluded by the United States whether Europe liked it or not.

"You’re playing with fire down there, Mr. Finch," Vance said, tapping the ash from a long black cigar into the foam below. "The Spaniards are finished. Everyone in Washington knows it. Everyone in New York knows it. The only people who don't know it are the dons in Madrid and the poor bastards starving in the reconcentration camps outside Havana."

"I am an engineer, Mr. Vance," Arthur replied, squinting into the dazzling glare of the southern horizon. "My business is with the air, not the government. An electric wave has no politics."

"Tell that to General Weyler," Vance chuckled, though there was no humor in it. "Old 'Butcher' Weyler may have been recalled to Spain last month, but the stink he left behind hasn't cleared out. The Cubans want independence, the Spanish army wants to save its pride, and the United States has fifty million dollars invested in sugar estates that are currently going up in black smoke. You set up a secret signaling device on a hill in Oriente province, and both sides are going to wonder whose artillery you’re aiming."

"It is hardly secret," Arthur said mildly. "It will produce a spark eighteen inches long that sounds like a pistol shot and smells like a thunderstorm. If anyone wishes to find me, they need only follow the noise and the scent of burnt ozone."

"Well," Vance said, blowing a ring of blue smoke toward the sky, "just make sure you keep your passport in your waistcoat pocket. In that part of the world, a man who can speak through the air without wires looks an awful lot like a spy to a nervous lieutenant with six Mauser rifles behind him."

The Don made landfall at Kingston, Jamaica, on a morning so bright and hot that it felt as though someone had struck an arc lamp directly overhead. The Blue Mountains rose behind the harbor like crumpled green velvet, their peaks lost in towering cumulus clouds that seemed to Arthur’s practiced eye to be bulging with several thousand amperes of atmospheric static.

The British relay station in Kingston was situated on a low promontory near Port Royal, where the skeletons of seventeenth-century pirate ships lay buried under thirty feet of coral sand. The resident engineer was an elderly Scotsman named MacIntyre, whose whiskers had turned the color of stale tobacco and whose skin had the tough, yellow texture of cured pigskin.

"Marconi is a dreamer," MacIntyre announced cheerfully as he poured two fingers of raw rum into tin mugs for himself and Arthur in the shade of a tin-roofed shed. "A clever lad, mind you. A very clever lad. But he doesn't know the tropics. You can spark across the English Channel because the air there is cold and clean, like a good Highland burn. Down here? The ether is full of devils, Finch. From noon until midnight, the static crackles so loud on the wire it’ll deafen you. It’s like trying to hear a clock tick inside a boiler works."

Arthur sipped the rum, feeling it burn a path down his gullet that rivaled the induction coil. "We’ve improved the decoherer, Mr. MacIntyre. We have a balanced magnetic hammer now. It taps the tube thirty times a second to clear the filings between impulses."

"Aye," MacIntyre said, squinting out through the heat shimmer toward the channel. "And when the lightning breaks over the Sierra Maestra, your hammer will be tapping like a woodpecker on laudanum, and your paper tape will look like a hen walked through an inkpot. Still, I’ve got your Jamaican receiver set up on the headland. Four hundred feet of copper wire suspended from a cedar mast that cost the company forty pounds sterling. If you manage to send anything through from Cuba, we’ll hear it. If we don’t, I’ll assume the yellow fever got you, or the Spanish firing squads did."

Two days later, Arthur boarded the small coastal steamer Santiago, a vessel of such precarious stability and dubious cleanliness that the crossing of the Windward Passage felt less like a sea voyage and more like an endurance trial designed by an inquisitor. The coal was poor, the boiler leaked steam from three poorly patched flanges, and the deck was crowded with wicker cages containing squawking hens, two pigs tied to a bollard, and several families of frightened Cuban refugees heading back to their homes after the autumn amnesty.

Arthur sat on his tool chest on the poop deck, his hat pulled low against the blinding salt glare. To the west, across the sparkling blue water, the purple spine of Cuba began to lift itself out of the horizon. It was not the flat, sandy shore he had imagined, but an enormous, jagged wall of limestone and jungle that seemed to defy entry. The Sierra Maestra mountains rose straight from the sea, their ridges cut by deep, shadowed ravines that looked black even under the noon sun.

He pulled Marconi’s letter from his pocket once more, looking at the technical memorandum attached to the back. Calculated transmission loss over seawater: 1.2 decibels per league. It looked so clean on paper, ruled in neat black ink on cream-colored stationery from the company’s offices on the Strand. But looking at that dark green wall of mountain rising out of the water, Arthur Finch felt the smallness of his copper wires and his glass tubes against the vast, indifferent silence of the earth.

He put the letter away, stood up, and moved forward to the ship’s rail. The Santiago was turning toward the land, heading directly for a narrow gap in the cliff face that looked, from this distance, scarcely wide enough to admit a rowing boat. Above the gap, perched on the chalk-white rocks like an eagle’s nest, the ancient yellow walls of the Castillo del Morro caught the late afternoon sun, its stone battlements scarred by three centuries of pirate shot and hurricane wind.

Arthur adjusted his watch. It was four o'clock in the afternoon, London time nine at night. In Chelmsford, the gaslights would be hissing in the cold mist, and the engine-driver would be banking the fires for the night. Here, the air smelled of allspice, woodsmoke, and the sour, swampy tang of the mangrove roots. He reached down, felt the handle of his Gladstone bag, and prepared to go ashore.

The channel into Santiago Bay was less a harbor entrance than a geological throat. As the steamer Santiago wallowed between the cliffs, Arthur could see the sea-worn limestone glistening with foam barely fifty yards off the port rail. Above them, the Castillo de San Pedro de la Roca—known to every sailor from Cadiz to Boston simply as El Morro—hung over the abyss like an eroded tooth. Bronze cannon, dark green with verdigris, thrust their muzzles through stone embrasures cut during the reign of Philip II. On the ramparts, a Spanish sentry in a striped rayadillo cotton uniform stood motionless, his Mauser rifle slung across his back, watching the steamer with the dull, bovine apathy bred of malaria and three years of garrison duty.

Arthur kept both boots planted firmly on the deck planks, his right hand gripping the brass-cornered edge of the instrument crate. Beside him, an aged Dominican friar was softly reciting the rosary, perhaps grateful for deliverance from the swells of the Windward Passage, or perhaps merely unnerved by the jagged teeth of the coral shoals that lay waiting beneath the emerald water. Once inside the neck of the channel, the sea swell died instantly, cut off by the high coastal ridge. The vessel slipped into an inland lake so vast and calm that the surrounding mountains mirrored themselves in the dark water without a ripple.

The smell of the place took Arthur by the throat before the engines had even reversed their screws. It was an overwhelming, complex broth of green cane molasses, rotting seaweed, untreated sewage, and roasting coffee beans, seasoned with the sweet, sickening odor of harbor mud baking under an equatorial sun. A flotilla of wooden skiffs and dugouts immediately swarmed the hull, their occupants shouting offers of boat-hire, fresh mangoes, cigars, and hand-woven straw baskets. Arthur ignored them all, keeping his eyes fixed on the low stone quay where a cluster of white linen suits and cocked hats suggested the presence of officialdom.

Disembarking was a study in controlled chaos. While passengers were shoved and jostled down a narrow wooden gangway by deckhands eager to begin unloading salt cod, Arthur refused to leave the cargo hold until he saw the six crates containing the spark apparatus safely swung ashore in the ship’s rope slings. Each crate bore the painted stencil of the West India and Panama Telegraph Company, along with enough official-looking red wax seals to impress an archduke.

"Cuidado!" Arthur barked in his best Castilian, stepping between a burly dockworker and the crate containing the bichromate cells. "That timber holds fragile instruments of glass and acid. If you drop it, the splash will take the skin off your legs down to the bone."

The stevedore paused, wiped his glistening forehead with the back of a filthy sleeve, and muttered something dark about English madmen and their boxes. But he lowered the crate to the stone pavers with noticeable tenderness.

Standing on the quay amidst the din of bawling mules and clattering iron-rimmed cartwheels, Arthur felt the heat strike down through his wool waistcoat like a physical blow. The sun was an open furnace. Within three minutes, his stiff linen collar had collapsed into a wet rag, and his palms were slick against the leather handle of his Gladstone bag.

"Mr. Finch, I presume?"

The voice was cool, clipped, and utterly unbothered by the ninety-degree humidity. Arthur turned to see a gentleman of about fifty years, impeccably turned out in an uncreased suit of white drill, a Panama hat of the finest weave, and carrying a malacca cane with an ivory knob. He had mutton-chop whiskers that were turning iron-gray, and pale blue eyes that looked as though they had spent three decades measuring the distance between British commercial interests and Spanish imperial bureaucracy.

"Arthur Finch, sir. You must be Mr. Ramsden."

"Walter Ramsden, Her Majesty’s Consul," the man said, offering a dry, firm hand. "Welcome to the frying pan of the Antilles, Mr. Finch. You look remarkably well-done for a man who left Kingston only forty-eight hours ago. I trust the crossing did not completely sour your disposition?"

"The vessel was somewhat agricultural in its accommodations," Arthur replied, shaking the consul’s hand, "but the instruments appear intact. That was my primary concern."

"Quite so," Ramsden said, glancing with mild curiosity at the row of pine crates now sitting on the quay under the watchful gaze of two harbor guards. "Mr. Marconi’s famous lightning machines. The governor-general’s office in Havana sent me two separate telegrams regarding your arrival. They seem convinced you are either an apostle of the new industrial age or an American agent disguised as an electrician. I assured them you were merely an Englishman with an obsession for brass screws and wire coils, which they found moderately reassuring. The Spanish mind understands madness far better than it understands republicanism."

"I am neither an agent nor a madman," Arthur said. "Simply an engineer under contract."

"In Santiago, Mr. Finch, those distinctions tend to evaporate around noon," Ramsden remarked dryly. He gestured with his cane toward a pair of two-wheeled carts drawn by pairs of scrawny oxen, their ribs showing like barrel staves beneath their hide. "I have arranged transport for your gear up to the warehouse behind the British consulate. It is situated on the hill near the Plaza de Armas. Cooler than the harbor basin, though that is not saying a great deal. The customs inspector, Don Eulogio, is waiting for us in the shed. Have you the manifest?"

Arthur pulled the packet of papers from his breast pocket, the edges already slightly warped by the damp air. Ramsden took them, flicked through the leaves with practiced speed, and nodded. "Good. The stamps are in order. Let us go through the charade before the man’s midday siesta overtakes him."

The customs shed was a long, low structure built of rough cedar planks, roofed with corrugated iron that hummed with heat like an oven plate. Inside, sitting behind a scarred mahogany counter littered with half-empty inkwells and yellowed manifests, sat a portly Spanish official in an unbuttoned uniform coat, his round face slick with perspiration. A heavy ceiling fan hung motionless above him, its pull-cord tied to a nail on the wall, the boy employed to pull it having vanished into the alleyway for a nap.

"Don Eulogio," Ramsden said in effortless, musical Spanish, bowing slightly. "Allow me to present Señor Finch, the chief engineer from London of whom we spoke. He brings the experimental apparatus for the West India cable station."

Don Eulogio peered through small, red-rimmed spectacles at Arthur, his nostrils flaring slightly as though attempting to smell heresy or contraband. He picked up the company manifest, wetting a thumb to turn the pages.

"Aparatos telegráficos," the Spaniard grunted, tapping a stubby finger on the paper. "Sin hilos. Without wires. How does one have a telegraph without wires, Don Gualterio? If there are no wires, where does the message go? Into the sea? Into the clouds?"

"Into the ether, Señor Inspector," Arthur interjected, stepping forward. "It operates on the principle of electromagnetic radiation, discovered by Professor Hertz in Karlsruhe. It is entirely for meteorological signaling between the shipping lines and the Jamaican cable head."

Don Eulogio looked Arthur up and down, unimpressed by the German pedigree. "The insurgents have no need of meteorology, Señor Finch. They know when it rains because they get wet in the bushes. What they need are signals. The rebel Calixto García is operating less than forty leagues north of here. If these boxes contain dynamos that can signal a rebel camp from the sea..."

"If they contained anything of the sort, Señor Inspector," Ramsden said smoothly, producing a small silver case from his waistcoat, "would I be standing here in the heat with my country’s seal on the consignment? Furthermore, the company has remitted the harbor transit dues in full, together with the customary... administrative inspection fees for the local maritime board."

With a movement of consummate discretion, Ramsden slipped a folded envelope of blue paper beneath the edge of the ledger on the counter. Arthur noticed that the envelope had a distinct thickness, the corners sharp and rectangular.

Don Eulogio’s hand moved across the counter like a sleeping toad snapping at a fly. The envelope disappeared into the drawer beneath the ledger with a soft scrape of wood on wood. The inspector dipped a steel nib into an inkpot, scribbled a flamboyant signature across the bottom of the manifest, and applied a heavy lead stamp that made the pine counter shudder.

"You may remove the boxes," Don Eulogio announced, rising from his chair with majestic indifference. "They are to remain at the British Consulate premises until the Captain-General has examined the technical reports. You are not to erect any masts exceeding twelve meters without municipal authorization. And Señor Finch?"

Arthur met the man’s watery eyes. "Yes?"

"Santiago is a city with two ears and forty mouths. If the air begins to smell of gun-cotton near your workshop, the civil guard will not ask for your passport before they clear the street with a volley. Keep your lightning to yourself."

"Understood," Arthur said.

Outside, the ox-carts were loaded under the supervision of Ramsden’s carriage driver, a towering Jamaican named Thomas who handled the packing crates as though they were filled with eggs. Arthur walked alongside the lead cart, his boots grinding into the dust of the Calle de la Marina.

The city of Santiago de Cuba climbed away from the water in a series of steep, terraced streets that seemed designed to exhaust horses and men alike. The architecture was an ancient, crumbling blend of Andalusian and Moorish styles: massive walls of pink and ochre stucco, low tile roofs with wide eaves that cast narrow ribbons of shadow onto the cobblestones, and tall, iron-barred windows—the rejas—behind which pale faces flickered like phantoms in the dim interiors.

Everywhere Arthur looked, the marks of the insurrection were stamped upon the stone. In the small plazas, groups of Spanish regular infantry sat on their bedrolls outside requisitioned municipal buildings, their uniforms gray with dust, many of them bearing yellow quarantine badges pinned to their lapels. Boy-soldiers, fresh from the villages of Galicia and Castile, huddled under stone porticos, shivering violently despite the blistering heat—the unmistakable ague of the vomito negro, the yellow fever that killed three Spanish soldiers for every one felled by a rebel bullet.

"A miserable sight, isn't it?" Ramsden murmured, walking beside Arthur with his cane tucked under his arm. "They land them by the thousands at Havana and send them out to die in the cane brakes. Weyler’s reconcentration policy has cleared the countryside, but it has turned the towns into charnel houses. There are twenty thousand starving peasants crowded into the shanties beyond the old trench lines. Typhus is doing what the insurgents couldn't."

"And the town itself?" Arthur asked, watching a patrol of civil guards trudge past, their leather crossbelts white against their blue jackets. "Is there fighting here?"

"Not inside the perimeter. General Linares keeps a firm hand on the garrison. But the perimeter is shrinking every month. If you walk two miles north past the stone quarry, you will find Spanish blockhouses connected by barbed wire. If you walk three miles, someone will fire a brass-cased bullet at you from a mahogany tree, and you will never know who pulled the trigger."

They turned off the main thoroughfare into the Calle San Basilio, where the streets were slightly wider and the houses larger. The British Consulate was an imposing two-story residence of whitewashed brick, with a massive double door of native cedar studded with heavy iron rivets. A bronze plate beside the door proclaimed Her Britannic Majesty’s representation, gleaming with the hard shine of daily polishing.

Thomas and two hired laborers unloaded the crates into a carriage house at the rear of the courtyard. It was an airy, stone-flagged space, shaded by an enormous tamarind tree whose feathery leaves filtered the harsh white sunlight into a cool, greenish gloom. A water cistern sat in the corner, fed by a copper pipe from the roof, and the smell of dry lime mortar and harness leather gave the place the practical, grounded feel of an English livery stable.

"This will be your laboratory, Mr. Finch," Ramsden said, leaning against the doorframe while Arthur carefully pried the top off the first crate with a small crowbar. "It has its own entrance from the alleyway, so your comings and goings need not disturb the official business of the consulate. I have had three worktables built of seasoned mahogany—ironwood, really; local pine rots to powder in six months because of the termites."

Arthur pulled away the layers of oiled straw, revealing the gleaming mahogany box of the ten-inch induction coil. The vulcanite pillars were immaculate, their black surfaces untouched by the sea damp, and the platinum contacts on the interrupter sparkled in the green light. He ran his fingertips over the lacquered copper windings, feeling a surge of purely professional relief.

"The insulation held," Arthur said softly. "The voyage didn't shake the core loose."

"A triumph for British joinery," Ramsden remarked, lighting a thin cheroot with a sulfur match. "Now, tell me truthfully, Finch. Can this contrivance really speak across fifty miles of sea to Jamaica without a cable?"

Arthur unpacked the second crate, lifting out the coherer mounting—a delicate brass frame supporting a small glass tube no larger than a pencil lead, filled with the silver-and-nickel filings that Marconi had dried with such care in London.

"In theory, Mr. Ramsden, it can speak across sixty. The curvature of the earth was thought to be an obstacle by the academics in Berlin, but Marconi showed that the waves follow the surface of the sea. Salt water is an excellent conductor. The problem will not be the distance. The problem will be the mountains."

He pointed through the open carriage house door toward the north, where the blue peaks of the Sierra Maestra rose like a serrated saw against the sky.

"The station in Kingston sits near sea level," Arthur explained, setting the coherer on the table. "Santiago harbor is surrounded by high ground on three sides. If we set up our aerial wire here in the courtyard, the hills will absorb the radiation before it ever clears the coast. We need an elevation. A cliff, a tower, or a headland directly overlooking the Caribbean."

Ramsden puffed a blue ring of smoke into the quiet air of the courtyard. "I had anticipated that difficulty. The West India and Panama Company has an old cable watch-station on the cliffs near the Morro—at a place called Aguadores, just east of the channel mouth. It is an old signal post built during the Ten Years' War. A stone shack, a hundred-foot flagstaff that was used for semaphore, and nothing around it but limestone scrub, cactus, and land crabs."

"Does it have an uninhibited view south toward Jamaica?"

"Nothing between the cliff edge and Port Royal but seventy miles of open water," Ramsden said. "And the Spanish garrison at the Morro is half a mile away, too far to hear the crack of your sparks if you shield the gaps properly. But there is a complication."

Arthur looked up from the packing case. "There is always a complication, Mr. Ramsden."

"The road between here and Aguadores passes through two Spanish checkpoints. The local commander, Lieutenant Colonel Toral, is suspicious of every cart that leaves the city gates. If you are going to haul several tons of wet batteries and four hundred feet of copper wire out to that headland, you will need a special transit pass signed by the civil governor himself."

"Can you obtain it?"

"I can obtain anything in Santiago, Finch, provided I give the right people the impression that it was their idea in the first place," Ramsden said, smiling thinly through the smoke. "Tomorrow morning we shall pay a visit to the Palacio del Gobernador. You will dress in your best frock coat, you will look sufficiently respectful when the governor mentions the glory of Spain, and you will say nothing about the speed of light or the properties of the ether. To them, you are merely an eccentric British electrician who wishes to study the electrical conductivity of Caribbean sea salt."

"And what happens if the war with the Americans comes before we finish the test?" Arthur asked, looking directly into the older man's eyes.

Ramsden’s smile faded, his blue eyes hardening into the look of a diplomat who knew precisely how fragile the world around him had become.

"The Americans are noisy, Finch. Their newspapers are screaming for blood, and their battleships are swinging at anchor in Key West like bulldogs on short chains. But President McKinley is a cautious man, and the Spanish queen regent does not want to lose her throne over a ruined island. They will bluster, they will file protests, and eventually the bankers will find a compromise. They always do."

He flicked the ash from his cigar onto the stone flags.

"Get your boxes unpacked, Mr. Finch. Check your batteries. Tomorrow we begin the battle with the Spanish circumlocution office. In my experience, it requires considerably more voltage than your induction coil."

Ramsden turned and walked back across the courtyard, his boots clicking rhythmically on the flags. Arthur stood alone in the dim carriage house, surrounded by his crates and the heavy, motionless heat.

From the street outside came the distant, mournful cry of a water-seller pushing his cart over the stones, followed by the metallic clatter of a sentry changing guard at the barracks up the hill. Arthur reached into his Gladstone bag, took out his brass pocket compass, and laid it on the mahogany table. The needle swung erratically for several seconds, twitching against the brass pin, before finally settling toward the north—pointing straight at the dark, silent mountains that held the secrets of the island, and the unseen fires that were waiting to consume it.
