Impressioning at the Sill

4:58. Present. Blank at the sill, no cut yet. Two porters, one locksmith, and a wall that will not stop counting to three. "The right profile," Wren says again. "You said you had it." Cazador crouches over the canvas. His hand goes to the fan of blanks — brass, silver, that one white metal — and stops. Hovers. A man who has never in his life fumbled a tool fumbles now, fingers spread over the wrong three blanks before they find the fourth. The one keyed to Iva's profile. He knows it by touch and still his thumb won't close on it clean. Wren logs the hesitation. *Locksmith selects blank, 4:59, hand unsteady.* She writes it because it is true, and because a burr on the man is a burr on the record. He brings it to the sill. Outside the salt. He does not cross. He kneels on the cold outer stone with the uncut blank held level, the way you'd hold something owed, and he says, "It won't cut itself, porter. Impressioning wants tension. Someone turns the key against the door while I read what the mechanism leaves. That someone stands on the far side." His jaw works. "Iva's side." The wall knocks. Three, pause, three. "No one crosses to turn it," Wren says. "The door turns against the blank. It's knocking, Cazador — it's already leaning on the leaf. Insert the blank from your stone. Let the far side press. You read the marks. I log every one." "That's not how—" He stops. Looks at the knocking wall. Looks at the blank. Understands, the way a craftsman understands a jig he didn't build: the thing on the other side wants in, and wanting is tension enough. He feeds the blank into the north keyway, through salt and nailhead, past the iron that stalls a crossing but was never a lock. The knock comes. The blank shivers in his grip. He draws it, and there are marks — bright scratches where the wards bit, where something on the far side pressed pins that have no business in a warded door and pressed them anyway. "Six points," he breathes. "Six." His file comes out. He starts to cut, slow, iterative, brass curling off in bright shavings onto the cold stone, and each pass he reseats the blank and reads the new marks and files again. It takes. It is not quick. The dawn does not wait for it. Marisol has said nothing. Now she steps off her inside stone — back, toward the cold wall she requisitioned iron for in 2001 — and lays her palm flat over the nailheads while he works, steadying it, the way she steadied it in thirteen. "Whichever key this cuts," she says, low, "it opens Iva's door. Not the child's. Not his." Meaning Halloran's, dragging still. "Two debts on this leaf don't touch a locksmith's blank. Yours." She means the authority. "And hers." She means Wren. "And I still owe the thirty years I spent building the wall your sister's key is about to open." Cazador's file stops. "You knew about this door." "I hid the leaf that maps it." Not warm-formal now. Costing her. "Iva crossed while it was buried where no one could confirm her close. My silence is in your sister's debt too, locksmith. Don't think you kneel here alone." Four hands, and now a fifth admitted plain — hers, not the authority's, hers, in the specific debt of one crossed woman. The pen under Wren's palm goes warm, then warmer, than it has gone all night. The file resumes. Brass falls. The blank enters truer each pass, from key-that-isn't toward key. "Almost," Cazador says. The sky finishes deciding. Grey to grey-gold at the window's edge — the crack between days, when a door left open cannot be shut, only answered. The wall knocks once. Not three. One. A single knock, and then a stillness that is not patience. The nib is warm in Wren's clear hand. She sets it to the line, no gap, and begins to write whose crossing the finished key will pay — and stops, because the blank in the keyway has just gone smooth against Cazador's turning wrist, all six marks met, and something on the far side has felt the key finish and gone very, very quiet. "It's cut," he says. "Don't turn it," Wren says. "Not yet. Not until the leaf knows who's holding it when it opens." Her pen is still on the line. The word is half-written. Dawn is in the room.
