The Tenth Key

The tenth key cost Sefa Iron-Quill a finger, a forged baptismal record, and four months pretending to be a woman who genuinely enjoyed bookkeeping. She did not regret the finger. The finger had been the cheap part. She stood now in the drying-room of the Cartographers' Guild, at the dead hour between the third and fourth bells, with the tenth key cooling in her palm and the smell of hot wax and copper filings in her nose, and she allowed herself precisely four seconds of satisfaction. She counted them. Sefa counted everything; it was the habit that had kept her alive in a city where magic came with an invoice. In Aldemar, you did not simply cast a spell. You filed for it. Every working — every mended bone, every lit lamp, every whisper carried across a room — drew its power from the Glass Vault beneath the Guildhall, and the Vault metered what it gave the way a miser meters wine. A licensed mage paid per draught. An unlicensed one paid in worse currency: the Guild's Assessors came, and measured the debt, and collected it out of whatever the debtor had that was warm. The keys opened the meters. Each key was a sliver of vault-glass keyed to one of the eleven great conduits, and a person holding all eleven would not need a license, or a meter, or the Guild's permission to be alive. A person holding all eleven could walk into the Glass Vault and simply turn the magic off. Sefa intended to be that person. She had been intending it for six years, since the night the conduits had been used to flood the Low Quarter — a licensed working, fully invoiced, perfectly legal — and her mother had been part of the debt collected. Nine keys were already hers, sewn into the lining of a coat that hung in a room no one knew she rented. The tenth was in her hand. She closed her fist around it, felt the glass warm to her skin like something alive and grateful, and turned to leave the drying-room the way she had come. The lamp by the door lit itself. Sefa went very still. Self-lighting lamps were a metered working, which meant someone had just paid the Vault for the privilege of being able to see her, and people did not pay the Vault for light unless they wanted you to know exactly how casually they could afford you. "Ten," said the man in the doorway. He was old, narrow, dressed in the slate-grey of a Guild Cartographer, and he was looking at her closed fist with the mild interest of a man appraising weather. "You have ten. I have wondered, these last months, who was taking them. The Guild assumed a rival house. I assumed a person. Persons are so much more interesting, and so much easier to disappoint." "I don't know what you mean." She said it flatly, without hope, because the line had to be said and they both knew it was scaffolding. "You mean to take the eleventh." He smiled, and the smile was the worst thing in the room — patient, almost fond. "I admire the ambition. I should tell you, though, before you spend another six years of your considerable talent on it, that you cannot. The eleventh key is not in a vault. It is not in a drawer. The Guild learned, a long time ago, that the safest place to keep a thing is inside a person who would rather die than give it up." He raised his left hand. His sleeve fell back from his wrist, and there, fused into the skin and the bone, glowing faintly with the cold milk-light of vault-glass, was the eleventh key. Sefa's four seconds of satisfaction had long since run out. What replaced them, standing in that lamplit room looking at the old man's wrist, was not despair. Despair was a luxury for people who had not planned. What replaced them was the slow, cold, familiar arithmetic of a woman recognizing a face — because she knew that wrist, she had seen it once before, six years ago, reaching down toward her through black flood-water and then, very deliberately, choosing not to. "Hello, Sefa," said the man who had let her drown. "You've grown up. Shall we discuss the eleventh key, or shall we discuss your mother first? I find the two subjects are difficult to separate."
