Chapter 47 The Far Door

The water above the open seam was black when they arrived, blacker than the trench water had ever been, black in a way that had nothing to do with depth. The instruments said it was fifteen hundred meters, which was nothing — a modest depth, a place where a survey ship had every right to be. But the water did not behave like fifteen hundred meters. The sonar returned a muddled picture, as if the sea floor had been chewed and the pieces were still settling. The temperature gradient was wrong, layered in a way that made Sano run the numbers three times. And the sound, the wrong song, came up through the hull not as a vibration but as a presence, a pressure against the inside of the skull, a song that had been the same four notes as everything else and had somehow been turned inside out. "It is not hostile," Ellison said, standing in the sonar room with his eyes closed, the way he had learned to hear. "It is not calling. It is not answering. It is — " he opened his eyes, and there was something in them that Tanabe had never seen before, " — it is crying out. The song is being taken. Somewhere down there, a keeper is singing, and the song is going out of it, and it cannot stop, and it has been singing that way for — " he stopped. "For longer than the sea has had names." Tanabe ordered the bell to be readied. Callahan insisted on going down with her, and she let him, because there was no one left alive who had the right to see this more than the man who had carried the song for half a century. They dropped through the black water in the little submersible, the dome of the bell dark around them, and the wrong song grew clearer as they descended — not louder, but clearer, the way a voice is clearer when you are close enough to hear the breath underneath it. The door was not like the second door. The second door had been carved and sealed and waiting, patient and enormous, its symbols flowing like water. This door was a wound. It had been made of the same material — the same patient stone, the same flowing symbols, the same deep geometry of the keepers — but it had been forced. The seals around it were broken from the outside. The symbols were not turning; they were frozen mid-word, as if the stone had been stopped in the middle of a sentence. And through the broken seam, the song came out thin and wrong, a keeper's voice being drained. "I know this song," Callahan said, and his voice was barely a whisper in the bell. "I have known it my whole life. It is the song we have been keeping. It is the same song. The First's melody, the Second's answer, the Third's chorus — it is all the same song, and this one — " he pressed his hand against the glass, " — this one is being sung the way it sounds when it is almost gone." Tanabe shone the lamp across the face of the broken door. The symbols were not only frozen. They were dying — fading, flaking, turning from deep green to grey to nothing, the way an old photograph fades when the light has been on it too long. And in the centre of the door, where a seal should have been, there was a hole — a hole the shape of a mouth, and the mouth was open, and the song was coming out of it the way breath comes out of a man who cannot stop. "Something has learned to drink," Tanabe said. "Something has learned to feed on the song itself. Not the singers. The song. The thing that comes between the notes." They surfaced in silence. The wrong song followed them up through the water, and when they stepped onto the deck of the Kairyu, the crew was standing at the rail, and every one of them was humming — not the song they had kept, but the wrong song, the eaten song, the thin and failing voice of the door below, humming it back as if they could not help themselves. "Quiet," Tanabe said, and her voice cut through it. "All of you. Do not hum that. That is not a song to learn. That is a song to mourn." The humming stopped. But Sano was staring at the chart, and his face was grey, and when he spoke, his voice was very quiet. "Captain. The dead patches. I did not see it until just now, but they are not random." He put his finger on the map, and he drew, slowly, a line — from the broken door, across the open water, to the edge of the chart, and beyond it, to the places the reports had described. "The silence is spreading. It is not coming from the door. It is moving toward it. The song is being drained, and the silence is following the drain, and if we do not find out what is drinking — " he stopped. "If we do not find out," Tanabe said, "the world will hum the wrong song, and the wrong song will be the only song left." The Kairyu raised anchor at nightfall, and the wrong song faded slowly behind them, and Callahan stood at the stern and watched the black water recede, and he thought about the squadron — the men who had died, the men who had hummed, the men who had carried the song across the sea to be rescued by the enemy and kept by strangers — and he understood, with the deep, wordless certainty of a man who has spent his life guarding a thing, that the song had survived the war only to face a worse enemy: a hunger that did not want to silence it, but wanted to own it, to drink it, to turn the world's newest song into the world's oldest wound. The keeper below them had been singing for longer than the sea had had names, and it had been fed on for longer than the war had lasted, and it had not stopped — it could not stop. And the hunger that drank it had not been born in the water. It had been born in the noise, in the ships and the bombs and the shouting, in everything the world had ever poured into the sea and then forgotten. That was the terrible math of it: the world had made the hunger, and the hunger was coming back to eat the only song the world had ever loved. Somewhere ahead, in the quiet waters, the silence was waiting for them — and something in the silence was humming.
