The mud of Lower Mesopotamia did not observe the ordinary laws of mechanics. At high tide along the Shatt al-Arab, it was an emulsified soup capable of swallowing an iron transit tripod to its knurled brass collars; under the afternoon sun, it baked into a crazed yellow crust that shattered like bad biscuit and threw off a blinding glare. Arthur Pendelton adjusted the eyepiece of his Troughton & Simms level, wiped the greasy rim of his thumb across the objective glass to clear a haze of evaporated river water, and cursed the Euphrates Valley Railway Committee in three distinct engineering dialects.

He had worked the wet cuts on the Great Western through the red marl of Devonshire, and he had laid ballast for the Highland lines through peat that shivered like blancmange under the weight of an engine. Those soils were stubborn, but they were Christian soils; they had bedrock beneath them if an engineer possessed the patience to drive piles until his timbers struck lime or granite. Here, south of Basra, there was no stone. There was only the silt of five thousand years of meltwater, unspooled from the Armenian mountains and beaten flat by a sky the color of zinc.

"Stand upright, Mr. Garrow," Pendelton called across seventy yards of steaming mudflat. "The rod is weeping five degrees to the west. A surveyor who cannot maintain a plumb line is merely an expensive tourist with a painted stick."

Thomas Garrow, his junior assistant, did not adjust the staff immediately. He stood knee-deep in the gray sludge of a tidal creek, his linen trousers plastered to his shins, slapping at a cloud of midges with a rolled pocket-book. Garrow had come out from the offices in Great George Street with two new drill suits, a pocket edition of Layard’s Nineveh and Its Remains, and the curious belief that the Ottoman Empire smelled primarily of cedarwood and rosewater. He had since learned that it smelled of sulfurated hydrogen, tallow-cooked mutton, and unwashed river boatmen.

"The wind is catching the vane, Mr. Pendelton!" Garrow’s voice carried thinly over the sucking lap of the river. "And my right boot has developed an intake. I believe the stitching dissolved ten minutes ago."

"Hold the staff against your ribs, tuck your elbows in, and cease debating the climate," Pendelton muttered, squinting through the crosshairs. The hairline divided the red-and-white face of the leveling rod at eleven feet, four inches. A miserable grade. To bring a locomotive of even modest cylinder capacity across this expanse would require an embankment seven feet above the spring tide line, with willow mattresses sunk beneath the formation to prevent the whole permanent way from sliding into the Persian Gulf.

He noted the figures in his field book with an HB pencil, the lead softened to grease by the ninety-degree heat of eight in the morning. His fingers were swollen from insect bites and gritty with the yellow dust that blew off the Arabian shore whenever the wind veered round to the west.

Behind him, seated on an upturned wicker hamper under the shade of a tattered boat-awning, Mr. Habib leaned forward and handed him an earthenware cup of cold tea. Habib was an Armenian from Baghdad who had survived three separate cholera outbreaks, two changes of Ottoman governors, and four expeditions of European surveyors. He possessed the melancholy calm of a man who knew that whatever the British proposed to build, the silt would ultimately reclaim it.

"The kaimakam of Fao sent another horseman while you were sighting the creek, Mr. Pendelton," Habib said softly in his precise, clerkish English. "He inquires again whether your tubes contain gunpowder, and if the Queen of England intends to run her iron carriages through his watermelon patches."

"Tell him the Queen has no designs on his melons, Habib. Tell him that if the railway comes through, his melons will reach the markets of Aleppo in three days instead of three weeks, where they may rot at twice their present value."

"I have told him this twice," Habib replied, watching a gray marsh-hawk circle above the date palms on the Persian bank. "He says Aleppo is full of thieves and Syrian Christians, and he prefers his melons to stay here. He also asked why an iron road cannot go across the desert where there are no ditches to measure."

"Because locomotives require water, and locomotives require coal, and the desert provides neither," Pendelton said, snapping the brass clasp of his field book shut. "Though if we encounter another three miles of this blue ooze, I may advise the directors to lay the metals across the moon instead. It would have a firmer sub-base."

He stepped away from the tripod, feeling the familiar, grinding ache in his left hip—the souvenir of a collapsed retaining wall outside Bristol six years prior. Pendelton was thirty-four, but the climate and twenty thousand miles of line-surveys had salted his beard with white and tanned his neck to the consistency of harness leather. The younger men in the London office spoke of the East with a kind of classical agitation, murmuring of Nebuchadnezzar and Alexander between their drafts of stout at the Cheshire Cheese. Pendelton saw the Tigris and the Euphrates primarily as drainage systems with an inexcusable lack of culverts.

"Pack the brasses," he told Garrow, who had dragged himself out of the creek with an obscene squelch. "We have two miles of riverbank to run before the sun gets overhead, and then we must meet the consular agent’s steam launch at the telegraph station."

Garrow wiped his face with a handkerchief that had long ceased to be white. "Do you think they will actually build it, sir? The line from the Mediterranean to the Gulf? The newspapers at home make it sound as though the first train will be steaming into Kuwait by next Christmas."

Pendelton laughed, a short, dry bark that stirred a pair of kingfishers from the reed-bed. "The newspapers are printed by gentlemen who have never seen five feet of alluvial mud dry out and crack into blocks the size of coffins. To cross the Shatt al-Arab, Parliament will have to vote three millions of money, and the Sultan will have to sign forty different firman documents, each requiring a bribe larger than the revenue of Kent. By the time the first sleeper is laid here, Mr. Garrow, you and I will be retired on half-pay, growing cabbage in Surrey and complaining about our kidneys."

They worked their way north toward the palm groves, their two Arab chain-men dragging the heavy steel links through the reeds. The chain clinked with a dull, wet sound. Every sixty-six feet, an iron peg was driven into the silt; every hundred yards, Pendelton took an angle against some distant, featureless mark—a lone date palm with a severed crown, a whitewashed tomb of a local saint, or the black hull of a stranded Turkish gunboat that had been rusting in the reeds since the Crimean War.

The river was wide here—nearly a mile across—a yellow, muscular flood that seemed less like a stream than an inland sea draining out between walls of gray mud. Dhows with high, raked sterns crept against the current under vast lateen sails, their crews poling through the shallows with long bamboos, shouting rhythmic, mournful chants that drifted across the water like the cries of sea-birds.

Toward noon, the heat became an actual weight, descending from the pale zenith like an iron plate. The air smelled of salt and dead vegetation. The horizon ceased to be a straight line and began to shimmer, detaching the date groves from the earth so that they floated in the sky like green islands suspended over silver lakes of mirage.

"Level off," Pendelton said, his shirt sticking between his shoulder blades. "We can do no more until the refraction settles. The bubbles are jumping in the vials like live fleas."

They took refuge under the thatch of an abandoned mud brick hut that had once belonged to a river watchman. It was dark inside, smelling of dry dung and old reed mats, but the air was five degrees cooler than the furnace outside. Habib produced bread, some hard white goat's cheese that tasted of brine and hair, and three small, bitter cucumbers.

Garrow dropped onto his haunches, his head between his knees. "I had imagined ruins," the boy said, chewing listlessly. "Towering walls. Bas-reliefs of winged bulls with bearded faces. The sort of thing Mr. Layard drew for the Illustrated London News. This is simply... salt. It looks like the mouth of the Thames if the world were dead."

"The ruins are five days' march north and west," Pendelton said, cleaning the lenses of his binoculars with the silk lining of his waistcoat. "Out in the dry desert, where the rivers changed their beds three thousand years ago and left the cities behind like flotsam after an ebb tide. Down here, there is nothing older than sixty years because the silt buries everything. If a man drops his watch in this mud, his grandchildren will need a steam dredge to find the chain."

"Yet they found things at Babylon," Garrow insisted, looking out through the low door at the white glare. "Rawlinson brought home inscriptions that go back before the Greeks. Before Moses, some of them say."

"Rawlinson is an officer with a taste for old brickwork," Pendelton said. He had little patience for the London societies and their debates over biblical geography. "And he was digging in dry gravel. If you want to lay a bed for forty-pound iron rails, you don't look at the inscriptions on the bricks; you look at their crushing strength. Most of the old stuff in this country is sun-dried clay. It turns to porridge the moment a winter shower touches it. A single locomotive—an ordinary six-coupled goods engine—would push a palace of Nebuchadnezzar through to China in thirty seconds."

Habib looked up from slicing a cucumber with his horn-handled knife. "There are mounds even here, Mr. Pendelton. Not by the water, but inland, between the rivers where the sheep go in winter. The people call them tells. Some are only gray heaps where the pottery lies thick, but some are very high. When the wind blows hard from the south, after the rains, the boys find beads of blue stone and pieces of gold leaf the size of fish scales."

"Tombs," Garrow said with a sudden revival of interest. "Sumerian?"

"Old," Habib said, shrugging his shoulders under his black wool jacket. "Older than the Turks. Older than the Caliphs. When my grandfather was a boy in Mosul, the Frenchmen came with spades and said the mounds were built by the giants who lived before the Flood of Noah. But the Arabs say they are the rubbish heaps of kings who were turned into jackals for their sins."

"They are the rubbish heaps of people who didn't understand the use of lime mortar," Pendelton remarked, checking his pocket watch. It was a sturdy English lever in a silver hunter case, its face slightly yellowed by damp. "Twelve minutes to one. The launch should be at the jetty."

He stepped outside into the furnace-blast of the midday air. His eyes throbbed behind his tinted spectacles. In the distance, half obscured by the boiling mirage of the flats, a smudge of black smoke moved against the green background of the Persian shore. It was the Comet, the little iron paddle-steamer belonging to the British Residency at Basra, panting its way down-channel with the mail bags from Baghdad.

They gathered their gear. Pendelton hoisted the Troughton & Simms himself; he never trusted an Arab porter or an English assistant with the parallel plates. The instrument was his own, purchased with forty guineas of his savings when he had left the service of the North Eastern Railway to take up this foreign commission. It had accompanied him to the zinc mines of the Asturias and the railway embankments of the Peloponnese; its mahogany box was scratched and battered, but the spirit levels were true to two seconds of arc, and the crosshairs were made of the silk of an English garden spider, stretched across the diaphragm in an instrument-maker’s shop in the Strand twenty years ago.

They reached the telegraph jetty—a rickety platform of unbarked palm logs driven into the mud and topped with split bamboo—just as the Comet backed her paddles, throwing up a great churn of yellow foam that smelled of river sewage. The vessel was a low-pressure boat with two skinny funnels, her decks sheltered by double awnings of bleached canvas beneath which two white-uniformed officers stood beside a small brass nine-pounder gun.

A young lieutenant with the yellow skin of a long residency in the Gulf leaned over the bridge rail and touched the brim of his solar topi.

"Mr. Pendelton?"

"The same," Pendelton shouted above the wheeze of the blow-off pipe. "We have the levels run to the third benchmark, Lieutenant. Another week and we shall have the center-line marked as far as the Turkish battery."

"You can leave the markers where they are, Mr. Pendelton," the lieutenant said. He didn't sound particularly interested in the center-line. He produced a thick packet from his tunic, tied with red tape and bearing the dark red seal of the Political Resident in Turkish Arabia. "I have dispatches for you from Basra. Arrived by the desert post from Damascus last night."

Pendelton caught the bundle as the steamer drifted within three feet of the logs. The paper was heavy, rough-edged, and limp with humidity.

"Trouble with the Porte?" Pendelton asked. "The kaimakam was being difficult about the right-of-way this morning."

"Not the Porte," the lieutenant said, ringing the engine-room telegraph to half-speed ahead. The paddles began their slow, thumping churn again, carving the mud into brown eddies. "The Consul-General wants you in Baghdad, Mr. Pendelton. Or rather, someone in London wants you. Some scientific business up-country. The letters are marked Urgent and Imperial, though what could be urgent in this God-forsaken swamp is beyond my navigation. We can give you a berth as far as Margil if you come aboard now."

Pendelton looked down at the packet. Across the front, beneath the printed heading of the Euphrates Valley Railway Exploration Committee, was written in a hurried, spidery hand: Addressed to Arthur Pendelton, M.I.C.E., care of the British Consulate, Basra. To be forwarded with all haste.

"Garrow," Pendelton said, not looking up from the seal.

"Sir?"

"Get the leveling rod into its case. We are going up-river."

"Back to the town, sir? To Basra?"

"Further, I imagine," Pendelton said, turning the thick parcel over in his palms. His thumb caught on the wax. It was stamped with the device of the Board of Works, but beneath it, pressed directly into the crimson wafer, were three words in small, clean Roman type: Sub-Surface Survey.

He had never heard of such a department in all his years on the iron. A survey was run upon the surface of the earth, where the levels were plain and the gradients were calculated against the sea. Sub-surface was the business of miners, or gravediggers, or the lunatics who spent their lives poking through the dust of dead empires with kitchen knives.

He looked back once across the flat, trembling expanse of the Shatt al-Arab. The tide was turning, and the salt water from the Gulf was backing into the creek they had measured that morning, drowning their red-and-white pegs one by one beneath the yellow silt.

The cabin of the Comet smelled of bilge water, hot lard, and the sour wool of the commander’s spare uniforms. It was six feet square, situated directly abaft the boiler casing, so that every stroke of the piston transmitted a shudder through the deckbeams that rattled Pendelton’s ink-bottle inside its brass gimbals.

Pendelton sat at the small swinging table, his pocket-knife peeling away the red wax seals of the Foreign Office packet. The wax came off in flaky crimson chips that smelled faintly of pine resin and oil of cloves. Garrow stood in the doorway, his head ducked to avoid the deck beams, holding a tin cup of tepid river water that he swung in rhythm with the steamer’s roll.

"What do the mandarins say, sir?" Garrow asked. "Is it a fresh line of levels? Are we to survey up to Hillah?"

"The mandarins," Pendelton said, unfolding four sheets of heavy blue vellum that crackled like dried hide, "are not concerned with our levels. Nor, it seems, are they particularly concerned with the Euphrates Valley Line."

He flattened the top page with his palm. The heading was printed in crisp, clear copperplate: Foreign Office, Downing Street, June 14th, 1858. Below it ran a dense web of bureaucratic prose, signed by an Under-Secretary of State and countersigned by two members of the Managing Board of the Euphrates Valley Railway Exploration Committee.

Pendelton read aloud, his voice flat and deliberate, suppressing the mounting irritation that gripped his chest.

"'—whereas the Committee has received urgent representations from the Trustees of the British Museum, supported by Her Majesty’s Consul-General at Baghdad, regarding the technical difficulties encountered at the excavations currently conducted under the direction of Mr. Henry Austen Layard’s former assistants near the lower Euphrates—'"

He stopped, lifted his spectacles, and rubbed the red crease they left on the bridge of his nose.

"They are re-assigning us," Pendelton said. "Or rather, they are re-assigning me. You, Garrow, are to return to the Residency at Basra with the instruments and await further instructions from London."

Garrow stared at him, his tin cup suspended halfway to his mouth. "Re-assigned? To an excavation? But we are railway men, Mr. Pendelton. We have two miles of marsh center-line to peg out before the tide washes away our bench-marks."

"The Board does not care about our pegs," Pendelton replied, his eyes running down the second page. "Listen to this: 'The nature of the subterranean works undertaken at the mound known as Tell al-Saffar has exceeded the capacities of native labor and ordinary antiquarian oversight. The extreme depth of the shafts, combined with the treacherous nature of the unbaked brick strata, has resulted in repeated structural collapses, threatening both the lives of the workers and the preservation of such artifacts as may be contained therein. You are therefore directed, upon receipt of this dispatch, to suspend all surface railway surveys and proceed forthwith to the said location...'"

Pendelton let the letter drop onto the table. "They want a clerk of works. They have dug a hole too deep for their spades, and now they want a railway engineer to put props under their mud."

"Tell al-Saffar," Garrow repeated, trying the name on his tongue. "Where is that? I don't recall it on the Admiralty charts."

"It isn't on the charts," Pendelton said dryly. "The Admiralty charts only mark the salt marshes and the places where gunboats run aground. Habib!"

The Armenian clerk stepped into the small cabin, stepping over the sill with the practiced grace of a man who had spent half his life on river boats. He looked at the blue vellum papers on the table, then at Pendelton’s face, reading the mood before a word was spoken.

"You know this place, Habib? Tell al-Saffar?"

Habib’s dark eyes narrowed slightly. He plucked at the fringe of his woolen sash. "It lies six miles west of the old river bed, south of Shatrah. It is not a place where men live, Mr. Pendelton. The Bedouin graze their goats near it in the wet season, but by midsummer there is no water within three hours' ride. Only the gray mounds and the salt."

"What kind of mound is it?"

"A big one," Habib said. "High as a church tower, but broken down by the rain. The lower people call it the Mound of the Coppersmiths, though no one remembers coppersmiths working there. They say that when the rain washes the ditches, the earth bleeds blue dust."

"Copper carbonate," Pendelton muttered automatically. "Malachite or azurite. A standard surface stain in copper-bearing sandstones. But there is no sandstone in this valley. It is all river mud for three hundred feet down."

"Perhaps the ancients brought the ore from the hills," Garrow suggested. "The Persians, or the Babylonians."

"The Babylonians used mud-brick and bitumen," Pendelton snapped, tapping his fingers against the table. "When they wanted stone, they hauled it down the river on rafts from Nineveh at enormous cost. They didn't haul tons of unrefined copper ore across sixty miles of waterless desert merely to leave blue dust in a mound."

He picked up the third sheet of the dispatch. Attached to it by a silver pin was a smaller sheet of cream paper, folded twice and bearing the stamp of the British Museum. The writing here was not the formal copperplate of a Foreign Office clerk, but an urgent, scrawling hand that leaned wildly to the right, as though written on a knee in a moving carriage.

"'Dear Pendelton,'" the letter read.

"'If this reaches you, you will no doubt be cursing my name and the Committee in equal measure. You are a practical man, and you will consider this a distraction from your honest iron and sleepers. I ask you to set aside your prejudices for thirty days. What we have uncovered in the lowest trench at Saffar does not conform to any stratum hitherto recorded by Layard, Rawlinson, or Loftus. The masonry is not sun-dried; it is not kiln-burnt in the manner of Nebuchadnezzar; it presents mechanical difficulties that defy our modest understanding of ancient masonry.'"

The letter was signed C. H. Loftus, Field Director.

Pendelton folded the paper slowly and smoothed the crease with his thumb. "Loftus was at Warka three years ago. He is a sensible enough fellow for an archaeologist—knows how to use a dumpy level and doesn't spend all his time trying to prove the Book of Genesis."

"Are you going to go, sir?" Garrow asked.

"I have no choice in the matter, Mr. Garrow," Pendelton said, his tone clipped. "This dispatch is signed by the Secretary of State. If I refuse, my secondment from the railway committee is canceled, my draft on the Ottoman Bank is revoked, and I may spend the next six months paying my own passage back to London on a cattle boat. In Her Majesty's Service, an engineer goes where he is told, even if he is told to build a railway across the bottom of the Sea of Galilee."

He stood up, his shoulders brushing the carlings of the deck overhead. "We dock at Basra within the hour. You will take the heavy survey gear—the transit, the steel chains, and the spare levelling rods—to the Consulate storehouse. Deposit them under lock and key. Keep your own field book clean and dry. I shall take the light pocket level, the five-foot measuring rod, and my personal tools."

"And me, sir?" Garrow asked, a faint look of hope crossing his sunburnt face. "Am I not to accompany you to the mound?"

"No," Pendelton said firmly. "The dispatch is explicit. 'One engineer officer.' Besides, someone must stay near the telegraph at Basra to receive the monthly abstracts from London. If the Committee decides to abandon the Shatt al-Arab line while I am poking through ancient brickwork, I shall need someone here to make sure our horses aren't sold by the Ottoman police."

The British Consulate at Basra was a low, whitewashed structure built around a mud-paved courtyard that smelled of rotting dates and horses. A creaking punkah, driven by an exhausted Indian boy sitting in the shade of a lime tree, stirred the damp air of the consul’s office without cooling it.

Major Taylor, the Acting Consul, was a plump man whose white linen tunic was permanently stained with yellow circles under the arms. He sat behind a desk of native mahogany, fanning himself with a palm-leaf fan while a clerk stamped papers with red ink.

"It is an extraordinary nuisance, Pendelton," Taylor said, tossing a heavy leather pouch across the desk. "The whole district between Shatrah and the hills is unsettled. The Muntafiq tribes are raiding the river traffic again, and the Pasha in Baghdad hasn't paid his troops in six months. Now I am expected to provide an escort for an engineer who wants to look at old bricks."

"I have no desire to look at old bricks, Major," Pendelton said, settling his hat on his knee. "I am acting under instructions from Downing Street. If you wish to argue the necessity of the mission, I suggest you send a cable to Lord Malmesbury."

Taylor grunted. "The telegraph cable from Kurrachee was broken by a storm off the Musandam peninsula three days ago. We are as isolated here as if we were on the moon. However, I have arranged six mules and four armed irregulars—Bashi-bazouks from the Turkish garrison—to see you as far as the canal head. Beyond that, you must depend on Loftus’s Arab guards."

"And the equipment?"

"Two chests of provisions, three skins of water—though you will have to boil every drop if you don't wish to die of the flux—and a bill of credit for sixty Turkish liras drawn on the merchant Shylock in Shatrah. He will give you silver, but he will take ten percent for the trouble, and he will look at every coin twice."

Pendelton took the leather pouch and weighed it in his hand. It was solid, heavy, and reassuring—the only truly reliable standard of measurement in the Ottoman Empire.

"When do we start?"

"At midnight," Taylor said, leaning back and closing his eyes as the punkah passed over his head. "To ride across the silt during the day is to invite sunstroke. The horses will drop, and your brain will cook inside your skull. Take the night tide up the canal to Suk esh-Sheyukh, then ride north before the sun turns the plain into an oven."

Pendelton rose and stepped out into the blinding glare of the courtyard. Garrow was waiting by the water butt, trying to scrape the dried Shatt al-Arab mud off his trousers with an old iron spoon.

"You're off tonight then, sir?"

"At midnight," Pendelton said. He walked over to his mahogany instrument case, which lay on a bench under the arcade, and lifted the brass lid. Inside, resting in their velvet-lined nests, were the brass tubes, the thumb-screws, and the delicate glass spirit vials of his trade. They were clean, bright, and uncompromisingly modern—the output of a workshop in the Strand where men worked to the thousandth of an inch with steel calipers and iron lathes.

He touched the cold tube of the level with his index finger. It felt entirely out of place in this city of mud, heat, and decay.

"Garrow," he said, without looking up.

"Sir?"

"While I am away, I want you to run a set of cross-sections across the mudbank behind the telegraph station. Use the three-foot rod. Record the depth of the silt at high spring tide, at ordinary high tide, and at low water. Plot the curve on logarithmic paper."

"Yes, Mr. Pendelton. And if the kaimakam complains again?"

"Tell him," Pendelton said, closing the box with a crisp snap of the brass latch, "that you are measuring the height of the flood for his own benefit, so that his watermelons do not drown. Men will believe any lie if you tell them it is for their profit."

By ten o'clock that evening, the heat had settled into a dense, oily stillness. The Shatt al-Arab lay like a strip of black velvet beneath a sky so thick with stars that the river seemed to reflect a double universe.

Pendelton stood on the stone quay beside the canal lock, watching his baggage being loaded into a long, narrow river-boat—a mashhooah—that swayed gently against the slimy timber pilings. The four Bashi-bazouks sat in the bow, their long-barreled flintlock muskets resting across their knees, their white turbans glowing faintly in the starlight. They were lean, dark men with teeth stained red from betel nut, and they looked at Pendelton’s iron-bound tool-chests with the sharp, calculated interest of professional bandits.

Habib sat in the stern, adjusting his woolen cloak over his knees. He had insisted on coming, despite Pendelton’s offer to leave him behind in the relative safety of the consulate.

"A man who travels with four Turks and no interpreter," Habib had remarked softly, "will find that his baggage arrives at the destination, but his throat remains behind on the road."

Pendelton adjusted his belt, which carried his heavy Colt revolver in a leather holster—a six-shot repeating weapon he had purchased in Liverpool before embarking. It was heavy, greasy with lard, and gave him a sense of practical comfort that no Foreign Office dispatch could provide.

Garrow stood on the quay, holding a stable lantern that threw long, dancing yellow shadows across the mud.

"Good luck, Mr. Pendelton," the boy said, offering his hand. His palm was hot and dry. "I hope... I hope the mound turns out to be worth the journey."

Pendelton took the hand, shook it once with a hard, square grip, and let it go.

"A mound is merely dirt, Mr. Garrow," Pendelton said, stepping down into the center of the boat. The wood groaned under his weight. "Dirt and dead men's pottery. In six weeks, I shall be back here, and we shall finish the survey down to the Gulf, no matter how many ancient kings are buried in the way."

The boatmen pushed off with their long ash poles. The boat glided silently out into the middle of the canal, away from the flickering yellow lanterns of the Basra waterfront, into the great, cool dark of the inland marshes.

Pendelton sat on his tool-chest, his knees drawn up, his hand resting on the polished horn grip of his revolver. Behind him, the low, dark line of the date groves slipped away, replaced by the endless, whispering walls of nine-foot reeds that lined the watercourses of the delta.

The air here smelled different—less of salt and ocean mud, and more of stagnant water, decaying vegetation, and the dry, ancient dust that the night wind blew down from the empty desert to the north. It was the smell of a land that had been drained, cultivated, flooded, and abandoned ten times over before the first iron rail was ever forged in England.

Pendelton reached into his coat pocket and pulled out Loftus’s letter once more. He did not need the lantern to read it; he knew the scrawled words by heart now.

It presents mechanical difficulties that defy our modest understanding of ancient masonry.

He spat over the gunwale into the dark water. Masonry was masonry. It was subject to the laws of gravity, the crushing strength of stone, and the lateral thrust of earth pressures. There was no masonry on earth—ancient or modern, Babylonian or British—that could not be understood by a man who knew his trigonometry and carried a plumb line in his pocket.

He pulled his felt hat down over his eyes, rested his elbows on the brass-bound corners of his instrument case, and listened to the rhythmic, wet splash of the boatmen’s poles driving them deeper into the silence of the plain.
