Chapter 12 Signal Drift

The calls increased. That was the fact Sabine could not make smaller, no matter how she arranged it on the page. In the first five weeks she had taken seven off-map calls. In the three weeks after the operator spoke to her directly, she and Ione took nineteen. Not all of them ended well. On the eighth night of the drift a man called from a corridor and would not walk. He had been in the Offline long enough that he had stopped believing in doors, and no matter how Sabine described the light at the end, he stayed where he was, and she listened to him talk about the buses that came and never stopped until the line clicked and he was gone. She had no unit to send and no body to find and no name to put on a form, and the next morning she wrote his entry in the pad and sat with it, and there was nothing in the apartment to blame and nowhere to put the weight, so she carried it the way she had carried a patient's death on the ambulance, which was to say not at all, which was to say she kept walking. Ione took it harder. She came in the next night with her jaw set and asked whether there was a way to reach them faster, and Sabine told her the truth, which was that they could only answer when the calls came in, and the calls came in when the calls came in, and everything else was waiting. The board was becoming porous, or the Offline was pressing against it, or the held were simply being joined by more of the held, and whichever explanation was true, the arithmetic was the same. More lines were lighting up. More people were finding the dead phones. The Offline was growing. She brought the pattern to Cato Bly on a Tuesday afternoon, in the records room, with the door closed. Cato listened to the whole of it without interrupting, which surprised her, because Cato interrupted everything. When she finished he sat back in his chair and looked at the reel of tape on the machine and did not speak for a while. "What you're describing is a switch," he said at last. "Not the building. The thing itself. The board at Gorse wasn't just a piece of equipment, it was a node. Every manual line in the north side ran through it. When the blackout took the power, the board went dark with every one of its connections still open in the jacks, and then the city cut it over to the automatic system and pulled the copper and walked away. Nobody pulled the cords." He looked at her. "The newer system didn't know those connections existed. It worked around them. You can't route around a thing that isn't on your map. So the old board stayed live, in the dark, underneath the new network, holding its jacks." "For forty years." "Forty years is nothing to a switch." He shrugged. "And the north side has been growing. Every tower, every new line, every cable they run up there crosses the old copper somewhere. You want to know why the calls keep increasing? Because the city keeps building over the thing that's holding the door open. You don't get more callers because more people are dying. You get more callers because more of the city is now close enough to the old lines to fall through." Sabine thought about the fire at fourteen Quillon, called in forty minutes before the smoke was visible. She thought about the man on the Penrose Street bridge, standing in water that was not there. She thought about Thea, whose body had lain in a hospital bed for eleven days while her mind walked a corridor that had no exit. The Offline was not just a place the stranded went. It was a place the city was bleeding into, one new cable at a time, and the blood was the sound of people who could not be found because they were in a room that had been left out of every map since 1983. "Can we get in," she said. Cato looked at her for a long moment. "You don't want to get in. You want to know where the door is, and the door is wherever the old board meets the new one." He turned to his terminal and pulled up a schematic, an old one, scanned and dusty, the north side's copper in crosshatch, the exchange at the center. He traced a line out from the building toward the river. "The Gorse Exchange fed the north side through trunk cables. There were five of them. Four went to the newer offices when they cut over. The fifth was abandoned in place, because it ran under the river and the city didn't want to pay to pull it. It's still down there. A trunk cable under the river, connected at one end to a board that never stopped, and at the other end to a junction box nobody has opened since the eighties." He stopped. On the screen the fifth trunk ran out from the exchange, under the gray band of the river, and came up on the far bank near the rail spur, where a small square box sat at the end of the line. "Where does it come up," Sabine asked. Cato tapped the screen. "Thurlow," he said. "The old transit yard. There's a service vault under the abandoned platform. It's the one the kid came out of." Sabine sat very still. The boy behind the wall of the station, counting trains until a white door appeared. The station the system insisted had no lower level. The trunk from the board that never stopped, surfacing in the one place in Rossmere where the Offline had already let somebody out. "There," she said. "That's where I'm going." Cato did not argue. He turned off the terminal and stood and went to the shelf behind him and took down a coil of cable and a headlamp and set them on the counter between them, and then he said the thing that she had come to him to hear, whether she knew it or not. "You'll want somebody with you who can read a schematic when the lights go out," he said. "And I'm the only person in this building who's ever been inside a central office." He looked at her, and for once he did not guess. "When you go down there, Ackerman, you take me. Because whatever is holding that door, it's been holding it a long time, and the longer a thing holds, the more it wants somebody to take over the shift." ---
