第8章 The Ward-Lattice

Skellick built the practice door in the deepest of Grissa's halls, where the echo went up the old quarry shaft and came back with nothing at all. He built it out of scavenged iron and two pounds of salvaged ward-chains, and he inlaid the frame with sigil-work in a copy of the master pattern, and Ophira watched him do it over the following three nights, and it was like watching a man write a language she had spent ten years reading and had never once been able to speak. A ward is not a wall. This was the first thing Skellick told them, and he told it with his hands, not his mouth. He took a brass rod and pressed the tip against the inlay at the top of the frame, and the pattern did not flare or spark or glow. Instead the air inside the frame went slightly wrong, the way air goes wrong over hot stone, and the rod's tip began to peel into itself, turning over and over like a strip of paper drawn into a flame. "That's the turn," Skellick said. "Every ward has a turn. The lattice on the Reliquary is a thousand small turns tied together, and if you cross it the wrong way the whole thing unwinds at once and takes the room with it." "How do you cross it the right way?" Boden said. "You don't cross it. You replace it." Skellick set down the rod and picked up a thin copper plate on which he had cut a copy of one section of the pattern, cut deep and cut twice, once with his own hand and once against the original. "The lattice reads itself constantly, every breath, and compares what it finds against what it remembers. If the picture in its memory is wrong in the right way, the lattice will read the wrong picture and call it correct." "Like a copied seal," Cadoc said. "Like a copied seal," Skellick agreed, and looked at Cadoc for slightly too long, because Skellick had never quite stopped being a forger, and a forger recognizes another man who has signed something he did not believe. They worked through the night. Bettany learned to walk the practice door a hundred times without touching the frame, because the lattice read the room and not only the frame, and a person who moved the air wrong would set it off. Boden supplied the rotation from his old notebooks and the corrections from his gate-friend, and taught the crew to move in the gaps between wardens the way he had once moved through the gaps between carts of contraband at the Fourth Gate. Cadoc supplied the inventory. He brought it down one page at a time, over four nights, folded into the lining of his coat. Cadoc came down every night with something new, and every night the crew learned a little more about the room they were going to stand in. He brought the inventory first: four hundred crates of black lacquer in the outer chamber, stacked three high along both walls, each one sealed with the crescent and numbered on the lid, and the numbers ran in a sequence that had a gap in it, and Cadoc could not explain the gap, and it was the gap that Ophira kept coming back to. He brought the weights next, and the weights told a story, because a crate of silver weighs what a crate of silver weighs and a crate of sealed glass does not, and the Cognate had been putting things in the outer chamber for three hundred years that did not match the numbers on their lids. He brought the ceremony notes last, six decades of them, written by clerks who had died before Cadoc was born, and in all six there was not one sentence about the inner sanctum, not one, as if the clerks of Vessant had been trained from their first day to write around the room at the center of their own building. "They're afraid of it," Ophira said. "They're not allowed to think about it," Cadoc said. "I'm not allowed to think about it. I've walked past the cabinet on the inner wall for six years and never once asked a question about it out loud, and I only know it's on the inner wall because I once saw it in a diagram that I wasn't supposed to see, and I have never told anyone that until now." The crew worked the practice door four hours a night. Skellick cut plates. Bettany walked it. Boden counted. Cadoc read his own handwriting aloud and then read it again, because reading is how a clerk remembers, and by the third night he could recite the entire Sealing from the first bell to the closing words without a single page in front of him. It was, Ophira thought, the strangest crew she had ever built. Not one of them trusted another, and yet they were already better than most of the crews she had run in her twenties, because every person in that hall had a reason to be there that was bigger than the money, and a person with a reason is a person who does not run. And on the third night, it came apart. Skellick was re-cutting a plate when his hand slipped and the burin went across the wrong line. The tiny error was invisible; it was a hair's breadth and the plate still read clean to the eye. He kept working. Twenty minutes later the practice lattice, which he had set to read the plate, did not flag the error. It read it as correct. Then, slowly, it began to unwind. The copper plate curled at the edges. The frame went cold. The inlay climbed into the air in slow grey threads, and the threads turned, and the whole practice door started to eat itself the way the brass rod had, because Skellick had made a copy so good that the lattice had chosen it as the master, and the master and the copy could not both be true. "Down!" Skellick shouted. Boden pulled Cadoc behind the water butt. Bettany flattened against the far wall. Ophira threw a horse blanket over the door and held it there, and the blanket turned grey and brittle in her hands, and she held it anyway, and after a long minute the threads stopped climbing and went out. The blanket crumbled into ash in her grip. The room smelled of burnt nails and vinegar. Nobody said anything for a while. Skellick sat down against the wall and put his ruined hands over his face. "I made it too well," he said. "You made it well enough that the lattice believed it," Ophira said. "That's not the same as too well. It's a different problem with the same answer." "What answer?" "On the night, we don't let the lattice read the plate slowly. We let it read once and move." She crossed the room and crouched in front of him. "You said it reads every breath. Then we give it one breath of a lie, and while it's deciding whether the lie is true, we're already through the door." "That's not a plan," Skellick said. "It's half a plan," Ophira said. "The other half is the Key." Skellick laughed, once, and it turned into a cough, and when it was over he looked at her with something that might have been respect or might have been fear. "There's a thing you're not telling us," he said. "I've watched you for three nights and there's a piece of this job you keep in your coat and don't put on the table." Ophira looked at him. She looked at Boden, who was steadying Cadoc. She looked at Bettany, who was not looking at her, which was how Bettany looked when he was listening hardest. "There's a book in the vault," she said. "Grissa wants three crates. I want the book. When it's in my hands, you'll all know what it is." "And if it costs us the job?" "It won't." "That's not an answer." "No," Ophira said. "It isn't." ---
