Chapter 79 The Reversed Greeting

The heartbeat under the world shortened all through the forenoon watch, and it did not shorten like machinery. Machinery accelerates in ratios; engineers can plot it, and Sano tried, and threw his pencil down in disgust before noon. Fourteen seconds became thirteen and seven-tenths, held, drifted, fell to thirteen and one-tenth as though turning over in bed, recovered, slipped again — the arrhythmia, Ellison announced to the chart room, of biology, of a pulse finding its strength the way a patient finds his feet on the second day of a fever, and the analogy was so exactly the wrong comfort that nobody thanked her for it. The doors felt it before any chart did. Along the whole ring, station by station, the round went on — the completed verse traveling door to door with its resolution inside, the great self-sustained circuit that had ended the leaning — but each door now opened a fraction wider with every pass, a hand's breadth becoming two, and the light along the trench country's seams, reported by the Meridian's floor-sweeping sonar, had begun to move like current instead of glow. Voss signaled from the north that the gap beneath the re-formed barrier breathed twice a minute now instead of once, and appended, in the flat northern grammar that had carried her through the loss of a continent's worth of instruments: it is the same rhythm everywhere, Captain. Whatever the ice used to hold is keeping time with whatever the mud is waking. I recommend nobody pretend otherwise. At 1142 local time the ocean paused. Not faded. Not faltered. Paused — every door on the ring stopping mid-phrase at the same bar-line, every keeper surfacing off every reef going quiet at once, the whale relay falling silent along two thousand miles of deep road, the Apprentice's single rebuilt note ceasing below the island, the choirs of the port cities, hearing it through hydrophone rebroadcast before their own ears could know why, hushing mid-verse in harbors on five continents. Forty seconds by the clocks at Greenwich; the longest forty seconds in the history of listening; and the vigil's papers record that aboard the Kairyu not one man or woman moved, because the pause had the quality less of silence than of a room when someone important has just risen to speak. Into it, from the south, from beneath the floor of the world, at a volume that was not loud but was somehow everywhere at once — inside the hulls, inside the chests, inside the teeth — the seventh station spoke its second word since the beginning of water. The four notes. The greeting. We hear you — the oldest courtesy of the vigil, the phrase Callahan had spent down to a whisper giving away note by note across an ocean and a year — rendered once, entire, and rendered backward: the last note first, the first note last, the melody walked home against its own grain, soft as a hand laid palm-upward on a table. Every hydrophone that pointed at salt water logged it. Every choir that heard it afterward described the same physical sensation, faithfully cross-culturally and uselessly to science: that of being greeted by something arriving rather than departing, which no one had known was a distinguishable sensation until they felt it. Then the pause ended the way pauses do, all at once and everywhere, the round resuming door to door as if embarrassed, and the displacement began. Sano plotted it hour by hour through the afternoon and into the dog watches, and the plot was the simplest and worst chart he had ever pinned to a board: a moving-off-of-sound, a change-of-weight in the floor of the ocean, rising out of the southern dark along the axis of the ring and closing on Iwo-koa. Speed constant. Course direct. No hesitation at the seamounts, no slowing at the doors it passed beneath — the doors, Ishikawa noticed with the hair lifting on his arms, leaned as it went by, every symbol-line bending east after it like grass after a cart, the way the vapor column had leaned at the Apprentice's first greeting. The foundation of the nursery was getting up from its chair, and the nursery was leaning to watch it go, and at four knots precisely — a walking pace; Ellison supplied that figure and refused to retract it — it would arrive beneath the island in five days. The world's navies spent those five days discovering the precise weight of irrelevance, which was good for them. Hollis signaled it officially within twelve hours — ALL FLEETS STAND DOWN FROM RESTRICTED FEATURE; NOTHING AFLOAT HAS STANDING IN THIS MATTER; FURTHER ORDERS WILL BE MUSICAL — and unofficially, on the flag circuit, in the dry voice the vigil had come to read like weather: Captain, for thirty years my job has been guessing what the other side intends. Last night every navy on earth received the same greeting backward from the same address, and this morning my opposite numbers have signaled me requesting, in writing, the correct reply. You are holding the only diplomatic service in existence. Do not lose the carrier. They did not intend to lose the carrier. Maeda intended to preserve him, and said so at length, and was overruled by the carrier himself at the evening conference, wheeled down from sick bay in a chair borrowed from the wardroom, frost on his blanket in the tropics, thin as a plumb line and twice as true. "The reply cannot be mine alone," Callahan whispered, when Tanabe put the admiral's message in front of him. "That is the whole lesson of the year and I will thank the log to enter it. Rask heard it from one machine. The whalers learned it from a rescue. The world caught it off wirelesses and bakery sisters, the way you catch laughter. When that thing arrives beneath us and asks its question in the only grammar it owns, the answer has to be standing already — every throat, every hull, every harbor that can hear the water." He looked around the chart room, at Halloway with her cipher case, at Sano with his ruined pencils, at young Okiwa who had learned the counter-melody off a Wellington wireless at fifteen and was now, God help the arithmetic of it, twenty-six. "Signal Hollis. Tell him the vigil is going to need every choir on this planet on station, in the water or on the wire, five days from dawn. And tell him—" the whisper concentrated, and the fan seemed to slow, "—tell him the old man intends to give the greeting back forward." The signals went out. The world, which had been waiting to be told exactly this without knowing it, turned its face to the sea. And late that night, alone at the transducer housing with the blankets and the frost and the ship asleep around him in the warm latitudes, Callahan heard the thing he had been listening down through six miles of water to hear, and it was not the rebuilding of the Apprentice's voice, and it was not the footsteps of the foundation coming north beneath the floor. It was simpler than either, and it entered the log in his own whispered dictation at 0311, transcribed by the duty officer whose hand shook on the pen: It said our hello backward, and I have stood at enough doors in my life to know the sound. A hello reversed is not a farewell, and it is not a challenge. A hello reversed is what you say when you are standing on one side of a door, holding the handle, deciding whether the people inside remember that you exist. Gentlemen, we have spent a year believing we knocked and the deep answered. We had it backward from the beginning. The knocking was always theirs. Something under the floor of the world has been waiting since before the ice to find out whether anyone inside would hear.
