第87章 The Third Key

It was the children who found the third key, and it found them first, which the schoolteacher said afterward was the only way it could have happened, given what it was. The Wednesday class had taken to going out to the old lighthouse at the very lowest of the summer neaps to dig in the worm of the retired light, because the worm had been a beach once, they had decided, and beaches give things back. It was a game. They dug with spoons and a trowel borrowed from the garden, and they came up with a pilfered pickle jar, and a bone the size of a thumb, and a thing that would have been a sovereign if a sovereign could drown slowly, and then the smallest of them, a girl called Morag, brought up from the black sand a small brass key. She knew enough to bring it wrapped in her hankie, because the schoolteacher had taught them that anything the sea gives back should be handled like a letter from someone larger than you, and she walked it up the brae to the reading room with the whole class behind her like a tide. The key was brass, and old, and it was wrong in a way the children could see before the adults named it. The stem was slender but the bit was cut shallow, its notches and wards soft-edged as if they had been filed by a hand that was describing something from memory, and stamped feebly into the bow was a mark that almost was the crown of strokes, and almost was not, the way a word written in a hurry keeps the shape of itself and loses the meaning. Iris brought her jeweler's glass and bent over it for a long time, and when she straightened she was very quiet. "This was cut against the grain," she said. "Whoever made this was copying a key he had held in his hand once, at speed, in fear, on a bench that was not his. The wards are half the true wards. Turn it and it will enter, and it will turn, and it will do nothing, because each of these cuts turns half of a single bolt and half of a bolt turns nothing at all." She laid it on the felt beside the two true keys, and the difference between them stood up like weather. "This is the straggler the letter warned us of, keeper. The sea has given it back, which is to say the sea has given us the problem it was keeping safe for four hundred years." They tried it, because a reading room tries everything, in the evening when the light went long and the gate was far away and the thing lay on the table asking, after a fashion, to be understood. Iris fitted the half-key into the western keyhole of the plate. It entered, sure enough, and it turned, a quarter, half, and then it stopped against a ward with a sound like a stone striking a stone, and no bolt moved, and Callum, watching from the door with his arms folded, said what the rest of them already knew. "It is a question wearing the clothes of an answer." It would not come free easily either; Neve worked it out with her knife and a deal of patience, and when it lay on the felt again it looked smaller for the attempt. "That is the difference," Wren said from her chair. "A key is a thing that keeps a promise. A half-remembering is a thing that keeps the shape of a promise and forgets the content of it. The gate must be shown the difference. That is all the warning ever said. It never said how." The man called Tulloch arrived three days later, on the afternoon ferry, with a leather case and a coat that had never been mended and the particular manner of a person who believes arithmetic agrees with him. He was small and neat and his eyes were the color of a spent fire, and he came up the stairs to the reading room as if he had been sent for, which he had not. He introduced himself without being asked — Edwin Tulloch, of the firm that had dealt in old things on the south coast for three generations — and he opened his case and laid out his papers on the table with the ease of a man who has done this in other rooms and found the rooms agreeable. The papers were the nephew's sold sheets, or copies of them: the bearings, the night-runs, the shape of the door, the little crown of strokes, and a bill of sale in a copperplate hand that named a sum and a seller's name which had been erased so hard the paper had worn thin. "My great-uncle paid for this knowledge, keepers, in good money, at a fair, in good faith," he said, and his voice had the flat courtesy of a schoolmaster explaining a date. "The family has rested their claim on it for four generations. All I ask is the running of the thing at the gate this autumn, in witness of that purchase, so that the road may be opened under the hands of the people it rightfully belongs to." The room went very still. Neve had gone quiet, which on Neve meant fury. Iris had set down her pencil. The children, who had been kneeling at the board pinning up the day's findings, had turned around without being told to. And it was Wren who answered, from her chair by the stove, because Wren answered the large claims. "Your family bought a secret," she said. "That is what the money bought. It never bought the door, and it never bought the beginning, and if you have kept the paper for four generations believing otherwise, then the paper has been keeping you more than you have been keeping it." She sat forward, and her voice found the register it used for the asking. "The sea does not read bills of sale, Mr. Tulloch. It reads hands. A sound is not a thing to be sold; it is a thing that is lent, generation to generation, and a loan is only ever called in by the people who can hold the whole of it. You hold a receipt. The keepers of this coast hold the thing itself." Tulloch looked at her for a long moment, and then he gathered his papers with exact movements and stood. "The autumn low will happen, keeper, whether the gate likes it or not," he said. "I will be there, with my family's title, and I will see the road opened under the law of the purchase, or I will see it opened under the law of the water, and either way it will be opened." He went down the stairs, and the harbor watched him take a room at The Salty Dog, and the whole village understood he meant to winter on their doorstep if he must, in the manner of a man who reads the calendar as a debt. That night Lila sat alone at the table with the three keys on the felt, the two that turned the bolt and the one that entered, turned, and stopped; and she thought about the frightened man who had cut the third in a hurry and gone down with it into the sea's keeping, and about the price the world had extracted from him, and about the collector who had carried the sounds east, and the honest keeper-kindred of Raudsker who had sung the missing verse for four generations without knowing it was missing. She set the two true keys in the first box under the felt, where they had always belonged, and she set the half-remembering apart, on the desk by the window, where she could watch it. The lamp burned low and the sea worked at the dark outside with its old patience, and Lila understood that the autumn would decide more than a reading. It would decide whether a promise and a purchase could stand in the same water, and the coast, which keeps its own arithmetic, had arranged to find out in front of witnesses.
