Chapter 51 The Water Road

They raised the seven spheres from their sockets at dusk, because the compass lived in the center of the instrument and the compass needed its circle near. That was what Anya worked out in the last hour of light, with her notebook open on her knees and the memory of the drowned world still settling in her eyes. The bearing was not drawn on any chart and not cut into any stone. It lived in the beat — glass against iron against the five vault spheres packed in their padded case — and a beat could be carried, but only if the instruments were carried too. So they lifted the spheres out of the black stone one by one, and the disc's light dimmed to an ember, and the drowned plain below them went quiet again, the way a church goes quiet after the congregation has gone home. Anya built the ring on the foredeck out of brass rod and spare clamps, thirty-six marks around a compass rose she drew herself, and she calibrated it through the night while the Akademiya stood off the plain with her lights burning. The principle was simple, and like everything simple it took eleven hours to make work. Hold the glass sphere at the center of the ring, count the pulses against the marks, and where the beat came strongest and steadiest, there the bearing ran. Off the true line the rhythm stuttered, hesitated, lost half its stride. On it, the spheres purred like a held chord. By dawn she could read a heading to within two degrees, and the heading ran due west, and Dmitri set the wheel to it without a word. The deck was crowded now in a way it had never been. Irina Basova had come up from the foundry with six divers, and six divers meant tanks and lines and gear lashed along the rail where the liferafts used to be, and it meant strangers in the galley and wet suits drying over every warm pipe. Their foreman was a broad, gray-headed man called Pavel who spoke perhaps forty words a day and hummed when he worked — old songs, low, half-swallowed, the kind a man learns young and never remembers learning. He re-rigged the Akademiya's diving station the first morning out, quietly, correctly, moving Dmitri's lashings and then putting them back better than he had found them, and Dmitri watched him do it with the expression of a man being robbed by someone more careful than himself. "We are carrying a museum," Dmitri said that night, at the wheel, as the coast of Thrace came up black on the port bow. "Five months you were one man with one sphere, and I could account for every kilogram aboard. Now I have seven instruments, a codebreaker, a woman who burned an archive, and her private navy. And we are going to take all of it through the Straits." "The Straits are nineteen miles of water," Nikolai said. "The Straits," said Dmitri, "are the most inspected nineteen miles of water on this coast. Tankers northbound, tankers southbound, pilots, patrols, radar that can read a gull's wing. And we will go through them at night, because you will not wait for daylight, and the woman's divers cannot be explained by any manifest I am willing to sign." Volkov solved it, which was becoming his function. He did not come aboard; he sent papers. Through a shipping agent in Istanbul whose name he did not give, a survey permit arrived by launch off Zonguldak — legitimate, expensive, stamped twice — naming the Akademiya as a hydrographic charter engaged in seabed mapping for an institute Volkov described, in the covering note, as "old, dull, and grateful for work nobody else wants." The permit covered the vessel. It said nothing about spheres, because no clerk in Istanbul would have believed it, and neither, Nikolai reflected, did he some mornings. They went through the Bosporus at three in the morning, in a procession of lights. The city hung above them on both shores — minarets, apartment blocks, the great floodlit mosques standing over the water the way lighthouses stand over rocks — and between the ship and the shore the traffic moved southbound in a slow parade of riding lamps, container ships deep-loaded, tankers riding high, each one a small lit town sliding past in the dark. Nikolai stood on the wing of the bridge with the glass sphere in a sling at his chest and listened to the beat under the engine drone. The rhythm did not care about the traffic, or the patrols, or the nineteen miles of inspection. It beat west, patient as a metronome, and above it ten million people slept on the shores of the water road, none of them knowing that under the whole length of their sea an older world lay keeping its shape. The storm caught them in the middle of the Sea of Marmara, a hard autumn northerly that came down off the hills without manners and turned the passage into four hours of survival. They hove to under a bare poles-and-bridle arrangement Dmitri had rigged once before, twenty years ago, and never expected to rig again, and the Akademiya rode it out with her head to the wind while the waves came through in gray slabs. Below, in the chart house, Anya kept the reading ring lashed to the table and called the bearing aloud every quarter hour, hour after hour, though the heading meant nothing with the bow swinging through ninety degrees at a time. She did it because she wanted the record. And the record showed the strangest thing any of them saw on the whole voyage: the beat never changed. Not when the bow swung east. Not when it fell off south. Through the worst of it, with the barometer dropping and the deck watch strapped in, the spheres pulsed steady on their line, unbothered, as if weather were a rumor from another world. "They know where they are going," Pavel said. It was the longest sentence anyone heard from him in a week. He stood in the chart-house doorway, wedged against the roll, humming almost inaudibly against the wind. "Stone does not hurry." By dawn the storm had spent itself and the Dardanelles opened ahead — narrow, green, the Asiatic shore close enough to smell, terraces and pines and the small white cemeteries of the coastal towns sliding by in the early light. The sphere warmed against Nikolai's chest as they entered the strait. He had learned the instrument's grammar well enough by now to trust the change: warmth meant approach, cold meant distance, and the pulse that had been a single voice since the foundry suddenly had company — a second tone underneath, faint, far ahead, like hearing a second singer join from another room of a large house. Anya heard it first. She was asleep on the chart table when it started and awake before her eyes opened, and she stood with both hands flat on the brass ring for a full minute before she would say anything at all. "It is answering itself," she said finally. "Or something ahead is answering it. The interval has closed, Nikolai. All the way across the Black Sea the beat was a call going into silence. Now the silence is thinner." She looked west down the strait, toward the Aegean she could not yet see. "Three thousand years is a long time to ask a question. I think something at the other end has just heard us coming." They cleared the last of the Straits at noon, and the Aegean took them — wide, glittering, indifferent, scattered with islands like the left-behind pieces of some older argument — and the eight circle ran on west into the open water, toward the place the flood had come from, at the pace of an aging research vessel making nine knots against a sea that had already been waiting longer than ships.
