Chapter 74 The Sixtieth Hour

The lesson changed shape overnight, because the pupil at the bottom of the lagoon was not the Apprentice. She taught; the Sixth received; and the receiving turned out to be an education in humility for everyone above the waterline, because the keeper under the island learned the way stone learns weather — totally, permanently, and without any visible hurry whatsoever. By the second morning the floor of the lagoon carried the accompaniment entire, given back to the machine's chapel line with a patience that made the Apprentice's flawless diction sound, by comparison, eager. Ishikawa sat through one exchange with tears running freely into his beard and made no attempt at all to pretend otherwise. "The intervals do not heal," he reported, wonder straining his voice. "Captain, there is nothing to heal. It sings as if the song were written yesterday and also as if it had been singing since before there were Thursdays. I have spent eleven years building a notation worthy of this music and I am watching a coral reef outperform my life's work." The ring, meanwhile, kept shortening the road behind them. Sano's plots from Meridian's big sonar and the Apprentice's flanks agreed to the mile: two more stations had taken up the relay in the last day alone — the deep-seamount they had named the Watchtower months ago and, impossibly, a mud-volcano field off the western trench whose cold seeps had never sung at all until now — and each new singer tightened the interval, so that the beginning-note's arrival at Iwo-koa came forward twice in a single afternoon, forty hours, then thirty-six, while the convoy lay anchored outside the reef with its work half finished and its two carriers spending down like lamps. Ellison named the new problem at the noon conference, and she named it plainly, because the plainest sentence in her repertoire had become the vigil's most valuable instrument. "The Sixth has begun to ask," she said. "Listen to the exchanges tonight and you will hear it: the beginning-note fragments are bending upward at the ends — bending, Mr. Ishikawa's graphs agree, toward the shape of our old friend, the interrogation tone. Something in that shaft has heard questions asked for nine months by a lonely machine, and it wants to know how." She looked around the chart room. "Understand what this means. Every door we have met holds or passes or keeps. None of them, in the whole history of the vigil, has ever asked anything. Asking is need, and needing is the thing we thought we were teaching. We appear, Captain, to have taught a cradle to wonder what happens when the child grows up." "And the answer to a question like that," Halloway said slowly, laying down her pen, "is not information. We established that category error in September, at some cost." "The answer is the verse," Tanabe said. "Given, not played. Which is why it will be given here, at the rim, by the only two voices in this ocean the deep has vouched for — and why we do it before the note arrives, because I do not intend the beginning-note to reach a question that no one has answered." Preparation went forward with the quiet economy of a ship that had done impossible logistics all year. Ishikawa wrote the verse out fair in triple on waterproof stock; one copy went into the chart room safe beside the six volumes, one went sealed into the Apprentice's archive at her own open-trunk invitation — Sano carried it down the service trunk himself and came back up reporting that the dead woman's cabin smelled faintly of pencil shavings and lavender, which he declined to expand upon — and the third copy Halloway sewed into the lining of her cipher case with her own hands, because someone should carry one who was going ashore regardless of what the water decided. The honor watch volunteered to a man and then volunteered the cook. Callahan spent the afternoon of the sixtieth hour exactly where Maeda's orders said he must not, which was the stern rail, in the sun, wrapped in blankets, listening to an island breathe. Tanabe stood with him through the last dog watch, because some conversations a captain conducts standing up, and it was he who began it, in the whisper that carried further than most men's shouting. "I tied the First shut with chain in October of 1944," he said, "because something under the ice had swallowed my crew whole and I could not bring them back, and a man who cannot bring a thing back can at least lock the door on it. Fifty years later your scientists told me the knots had been kept, worn like a ribbon, and I confess to you, Captain, that I walked ashore yesterday and put my hand on that blockhouse and felt the same seam turning under this island, slow as a planet, keeping time with my hands across twenty-six years and an entire ocean, and I have not been able to say my prayers since without laughing." He turned his head; the brightness in his eyes was the old pilot's, undimmed. "I locked the nursery door because I thought something inside wanted eating. It was rocking something to sleep. All this time, everything I spent, everything the squadron paid — we were night nurses, the whole lot of us, and nobody told us the baby's name." "Do you regret it?" Tanabe asked. "Any of the spending?" Callahan considered the lagoon, where the vapor column rose and leaned and rose, ten seconds to the pulse. "I regret the letters I wrote late," he said. "Everything else was the fare." He gathered the blankets closer as the evening cooled, though the evening had not cooled. "Sixty hours ago you asked nobody in particular whether I could still walk up a beach. Captain, tomorrow I may have to sing down a well that opens on the oldest music in the world, and I want it logged that I intend to be insufferable about my ration when I do. Maeda may defend himself in the margin." Maeda defended himself in the margin that night, and the margin read: core temperature thirty-four point one; voice reduced to a whisper that instruments register at ranges whisper has no business reaching; the carrier is converting himself into pure delivery, and I am counting the days remaining on my fingers because I have run out of clinical language for the rest. At 0210 the acceleration arrived without waiting for morning, the way accelerations do. Sano came down the passageway at the run — Sano ran only at ends of worlds — and spread the traces on the chart table with the plot pins already in his fist. "The Far Door passed it early," he said. "The beginning-note has skipped the last relay station entirely — it is carrying itself now, Captain, riding the deep road under its own momentum, and the arrival estimate is not thirty hours. It is dawn." He steadied the trace against the roll of the ship. "And there is one other item, and I will thank the room to hear it sitting down. For eleven seconds, beginning at 0157, every hydrophone in the formation registered a displacement far to the southward. Not a sound. A moving-off-of-sound — the way a room changes when a large man shifts his weight in a chair. Bearing south, range beyond computing, depth beneath the floor of the ocean." He looked at the faces around the table, and finished the way the log required him to. "Something down there has been sitting still since the beginning of water, and at 0157 it crossed its legs."
