What the Far Side Knows

Wren does not cross. That much she can hold on to. She stands on her own boards, the flood-year folio shut under her hand, and she counts the space between herself and the sill: three paces, maybe four. Enough that the cold air off the far side reaches her but does not touch the woman's face reach her voice. The woman waits. She has the patience of a column that will not square no matter how many times you cast it. "Madame," Wren says, because she will not say a name she was not given, and she suspects this one is offered like bait. "You'll not be told the entry I'm missing. I'll find it myself. That's the whole of the job." "So Master Corvin taught you." The woman tilts her head. The warded key at her collar swings, catches the lamp — and Wren, who has cataloged every bit and ward on the Row, sees at once that the cuts on it match no case she has ever posted. Slots filed to clear obstructions that stand in no lock she knows. A key for a door in no book. "He taught you a clean page is a lie. Did he teach you what an *honest* imbalance looks like?" Wren says nothing. She counts. One key. Zero matching locks. "It doesn't wander," the woman says gently, as if reciting Wren's own thought back to her from the far side of the sill. "An honest mistake wanders, Wren. Yours sits still. Month on month. Iij s. iiij d. — the same lodger, paying no rent." She smiles, and there is no cruelty in it, which is worse. "A fixed difference is never an error. It is a *counter-entry*. Someone posted a credit here with no departure to match it, and the books have carried it, quiet, for years. You are not casting up a mistake. You are reading someone's confession, one column at a time." The lamp gutters. Wren keeps her hand flat on the folio, over the closed account she has never had the nerve to read — the gate-keeper crossed out through the crypt door, the winter the water came. She does not let her eyes go there. If she looks, the woman will see her look. "You know my name," Wren says. Flat. "You know the sum. Both are in a book chained inside a locked house. So you've read a ledger I've never seen." The woman does not deny it. She only says, "There is more than one ledger, Wren. This district keeps its book. The place behind this door keeps its own — and it keeps it *perfectly*. Every arrival with its departure, debit against credit, nothing struck through because nothing is ever left unclosed." A pause, precise as a folio reference. "That is why I've come to the sill and no further. Their book has my account open. I cannot square it from this side." "Then square it from that one." "I would," the woman says, "if someone here would only post the entry." She steps back — not forward, back — into her own cold, and the strap hinges take her weight without a sound they should have made. "You'll cast the column a fifth time. You'll get iij s. iiij d. When you're tired of finding it, ask Master Corvin whose hand signed the flood-year folio at the closing. Then ask him what he closed." She is gone before the sill stops being a sill. The door that hung on no pintle Wren ever set is simply — jamb, reveal, wall. As if the arriving-hinge, having nothing to seat against in any book, had nowhere to stay hung. Wren waits until her hands stop needing something to do. Then they need it anyway. She opens the folio. She casts the column a fifth time, twelve to the shilling, twenty to the pound, the Roman sums squinting back. Three and fourpence. She writes in the margin, small: *cast up v times.* And under it, smaller, before she can lose her nerve: *not error. counter-entry?* She strikes nothing through. She leaves it standing. Then she turns the folio to the facing page, to the account she has shut every night for a year — and reads, at last, the name posted there in the debit column, crossed out clean through the crypt door in Master Corvin's own weak-tea ink. She knows the hand. She knows the name. She closes the book, softly this time, and blows out the lamp, and does not go home.
