第59章 The Breaking Ice

The front went at 0247 with a sound that the survivors compared, variously, to artillery, to a train falling off a bridge, and to the voice of God clearing His throat before deciding against speaking. Eleven miles of ice cliff, in three great sections and uncountable small ones, leaned out over the sea, hung for a heartbeat that instruments recorded and no one believed, and came down. The wave arrived at the anchorage forty minutes later as a gray wall four meters high, and it was met by four ships headed into it, because Tanabe had them underway and pointed at the sea before the horizon finished lifting, which was the only reason all four were still there to tell about it afterward. What followed was nine hours of work that none of them would have survived as spectators. The evacuation had begun at first light the previous morning, but light comes late in those latitudes, and Auster held more souls than her aircraft could lift in two days. Voss sent her people out in convoys of snow machines along the flagged route to the gate while the dome drummed behind them; the Bear took aboard ninety scientists and stood out with her decks awash in kit; Skua ran her boats through the growing brash field to lift stragglers from the ice edge, pull after pull, the coxswains conning by eye between floes the size of churches. And above it all the barrier kept shedding itself — sections the size of city blocks toppling in slow silence and then in roaring ruin, bergs rolling up from the depths with their undersides glowing faintly along old fracture lines, as if the note refused to stop merely because its roof had come down. The helicopter was the cost that almost was. Auster's last machine lifted at noon overloaded, in crosswind, off a pad whose snow was already sliding, and made four minutes of flying time before the crosswind won. It went into the sea upright and mostly intact, and eleven people got out of it into water at minus two, among bergs that were still rolling from the morning's collapse. Every boat in the anchorage started for them at once, and every boat would have been too late, and this was the hour in which the convoy finally saw what had been working under the ice beside them all along. The sea opened. Between the men in the water and Skua's leading boat, a lane of clear water appeared through the brash — straight, wide, impossible, walled by floes that moved aside with a deliberateness no current explains — and up through the lane, just under the surface, pale shapes passed like clouds passing under a sheet. Enormous. Slow. Attentive. Keepers such as no volume had described, such as no sonar sweep had ever hinted at: the singers who lived under the ice, unknown, unseen, present all along. Where the bergs threatened the swimmers they turned from their courses, nudged aside by bodies the size of ridges moving with the gentleness of hands. The water around the eleven warmed measurably — Ishikawa logged it, disbelieving his own thermistor — currents drawn up from some deep warmer stratum and laid precisely where heads were going under. The boat reached the last of them as he lost his kick, and hauled him over the gunwale coughing, alive, all eleven alive, while beneath the lane the pale shapes sank away without ever once surfacing fully enough to be looked in the eye. Below, in the same hours, the bell fought its way home. Ellison and Sano had gone down at dawn for a final instrument session — recording the chamber, the chord, the turning — and the break caught them at depth with the shaft already failing. The guide wires sang and then went slack; the winch crews' voices on the phones reported rock and ice descending the vent's throat in quantities no rig could fight. For six minutes, by the clock, the bell sat in the dark under a continent that was rearranging itself, and then the pale keepers came to them out of the black — three of them, rising slowly past the dome lights close enough to dim the bulbs — and a fourth appeared ahead, at the base of the shaft, where no passage should have existed, and the wall of ancient stone beside it simply opened, symbols parting like a curtain, a throat of new-made channel breathing upward where an hour before there had been four thousand feet of mountain. Ellison flew them up that channel on instruments and faith while it was being opened ahead of them and closed behind, and the last thing the sonar recorded before they rose into open water was the keeper turning back down into the dark toward the First Instrument, unhurried, taking up its station, staying with the music. They surfaced into the middle of the calving front, under a wall of ice taller than the masthead and leaning. Ellison did not remember the next ninety seconds clearly and said so, cheerfully, for years afterward: full power across the falling ground-swell, the glacier face pitching outward overhead with a noise like the end of geography, the bell skipping twice across water that had turned to broken glass — and then open sea, and the Kairyu's searchlight finding them, and thirty hands hauling the little submersible aboard while her hull ticked and steamed in the cold. No one died that day. The ledger of what did die was long enough: the shaft, gone; Camp Vigil, gone under a hundred million tons of fresh icefall; the Meridian's bow dome crushed by a shifting floe; two snow machines, a generator shed, and every fixed instrument on the barrier. The gate in the ice wall was closing as the shelf re-formed seaward, and the charts of the coast were dead letters by evening. But the hidden sea had new channels now — the sweeps showed them plainly, throats and seams the keepers had cut or uncovered, running from the buried chamber out toward the open ocean — and the sound coming up through the ships' hulls that night was unchanged, patient, unresolved, the chord holding its lean into the unfinished measure. And over the water where the barrier had stood, the air carried it too. That was the report no one knew how to file: the beginning-note, hanging in the open polar night with nothing beneath it but wreckage and sea, audible to bare ears on every deck, arriving without any medium the physicists could certify. The watch officers entered it in the logs as atmospheric phenomenon. The bosuns entered it as the sound the ice had left behind. Callahan, wrapped in two blankets at the stern rail, listened to it for an hour and gave it its true name in the hearing of the quarterdeck. "That is not an echo," he said. "Echoes fall off. That is the instrument playing to the whole sky now." He looked at Tanabe, and his eyes were bright and very far away. "We wanted the world to learn to sing, Captain. Nobody asked the world whether it would rather listen first." All through the anchored fleet that night, compass needles swung slowly off north and settled back, swung and settled, regular as breathing, and no deviation table explained them, and the older hands who noticed said nothing, because it felt less like malfunction than like something vast and patient nodding yes.
