The trapdoor shut with a thud that vibrated through the floorboards. Danica sank against a crate of tallow candles, her palms gray with soot from Perun's laboratory. Beside her, the storage vault smelled of cured hides, linseed oil, and stagnant brick. The safehouse was buried beneath a cooperage in the lower docks, muffled beneath the rolling clatter of iron-hooped kegs overhead. "Drink," Radoslav ordered, thrusting a clay mug of bitter chicory brew into her grip. Danica took it, her palms stinging from fresh scrapes. "They will track the wagon wheels. The watch had hounds." "The dogs lost the scent in the slaughterhouse runnels two streets back," he countered smoothly, tossing a sodden wool cloak into the coal bin. He looked immaculate despite the chase, save for a smear of black grease along his cuff. "No city guard sets foot in this alley without asking my factor for permission, and right now my factor is bribing their captain with imported salt." Across the narrow pine table, Lady Zofia sat rigid on a three-legged stool. Her vestments were torn at the shoulder, revealing pale skin smudged with lamp oil. She had not touched her mug. Her gaze remained fixed on the scarred oak grain, her knuckles pressed against her skirts until the linen creaked. "He was my blood," Zofia said. The tone was completely flat, stripped of its customary courtly cadence. "Perun was a disgraced drunkard, yes, but he was my cousin. And she had him slaughtered like an infected calf." "Elzbieta cleans her pens thoroughly," Radoslav said. "It isn't just Perun." Zofia raised her head, looking directly at Danica. The severe, pious posture she had carried through every assembly was fractured. "Three generations ago, House Rostova held the western grain silos. We owned the granaries that fed the lower river. When the great rot came in my great-grandfather's youth, he proved that the grain rot spread from contaminated seed bags distributed by the inner chapels. He wrote a treatise on the damp. He brought the rotten kernels to the assembly." She reached into her bodice and pulled out an iron key, tarnished and notched with uneven teeth. "They burned the granaries that winter," Zofia continued, her voice trembling with an old, cold fury. "They called it a cleansing fire from the heavens. My great-grandfather was declared an apostate and died in a cell beneath the river wall. They stripped our crest. They gave us back petty titles only after my mother crawled on her knees up the three hundred marble steps to kiss the hem of the previous high prelate." Danica leaned forward, setting the chicory down. "The exact same pattern. Elzbieta's kin lost their lands to court creditors during a drought. She spoke of it once at my welcoming feast—she considers every bad season a judgment on the crown's arrogance." "She didn't learn caution from her house's ruin," Zofia spat, her fingernails biting into the iron key. "She learned how to swing the cudgel. She took our downfall as a manual. My mother raised me to be pious enough to wash out our stain, to make me High Priestess so no Rostova would ever be broken again. And I served her. I shadowed you because I thought you were another charlatan whose arrogance would doom us all." "You brought me clover from the border dyke," Danica said softly. "Because it was alive!" Zofia slammed the key onto the raw oak table. The crack cut through the subterranean room. "The temple's holy ground was dead gray ash, and your patch of earth smelled like spring rain. God does not poison the dirt to test our prayers, Danica. Wicked women do." Danica reached across the rough wood and covered the younger woman's trembling knuckles. Zofia didn't pull away. Instead, her fingers clamped onto Danica's wrist with desperate strength. "The Grand Sanctum has an aqueduct pipe," Zofia whispered, leaning in. "My great-grandfather designed the sanctum's vaulted floor before his ruin. He cut an inspection flue behind the icon of the Horned Bull, hidden behind the cedar panels. It bypasses the guarded portcullises and opens directly into Elzbieta's private scriptorium. The key fits the service grate in the eastern undercroft." Danica stared at the rusted metal. "Her ledgers. The manifests for the quicklime and sulfur." "Everything," Zofia said. "Her correspondence with the alchemists, the receipts of payment from the temple reserves. It is all kept in the walnut bureau beside her altar. I know because I carried the wax seals to her desk every month. She trusts me to die for her orthodoxy. Let her see what that devotion buys." Zofia stood up, wiping the grease from her jawline with her torn sleeve. "I am going to the eastern cloister to watch the watch-rotations. If I am seen in my quarters, they will assume I fled Perun's quarters in panic, not treason. I will leave the garden wicket unbolted at second bell past midnight." Without waiting for an answer, Zofia slipped past the wool curtain and vanished up the ladder. Danica remained at the table, staring at the key. Fatigue sat behind her eyes like hot sand. She rubbed her brow, her mind already calculating—quicklime neutralized with weak acid, sulfur burns, the court assembly in two days. If they could not produce absolute, damning evidence before the council voted to brand her, science would not save her from the pyre. She rose and walked toward the small shaft of moonlight spilling through a sidewalk ventilation slit. In the corner of the cellar, set beneath the grate where thin moisture dripped, sat a shallow wooden crate filled with damp loam. Someone—perhaps an apprentice cooper—had planted sprigs of wild thyme and winter savory in it. Danica knelt, pinching off a dead leaf to let the lower shoots take air. The rich smell of humus ground down the panic tightening her ribs. Dirt was simple. Dirt answered to chemistry, not venom or crown mandates. Bootsteps clicked against the limestone. A broad shadow fell across the planter. Radoslav stopped two paces back. He had discarded his tailored doublet, wearing only an unlaced linen shirt that showed the corded muscle of his collar and shoulders. In the gloom, the harsh planes of his face looked softer, cut by gray light. "You are tending weeds while the royal guard searches the merchant quarter for your head," he observed. "Thyme isn't a weed. It fixes the soil's fungal rot if you dry it into powder," she murmured without looking up, carefully loosening the root ball of a seedling. "Everything has a use if you bother to understand its composition." "I have met three dukes this month," Radoslav said, stepping closer. The scent of cedar smoke and clove hung on him. "I have dealt with five high stewards and two dozen foreign factors. Every one of them spends his life calculating how to take something away from someone else. How to tax it, seize it, burn it, or hoard it." He knelt beside her in the floor muck, heedless of his dark breeches. Danica paused, her hand hovering over the dark loam. "I do not give a damn about the Deities of Soil and Sky," Radoslav said, his voice dropping to a low, quiet hum that filled the space between them. "And I don't care if you fell from the stars or crawled out of a peasant's ditch. I know what a ledger looks like when a kingdom is bleeding to death." He reached out. His calloused palm settled over her soil-stained hand, pressing her fingers gently against the fragrant thyme leaves. His skin was unexpectedly warm against her chilled knuckles. "I have known many nobles and many merchants," he said, his dark eyes holding hers with an intensity that stopped the air in her chest. "But you are the first person I have met who builds things. I want to build with you." The cool dampness around them receded. Danica looked at their joined hands—pale skin and dark, fine silk and common wool, both coated in the same dark loam. Her chest hitched. For months she had been an anomaly, an interloper trying to fix a broken realm while pretending to be an ethereal vessel for prayers she didn't believe in. He was the only one who looked at her and saw the work. "Radoslav," she began, her voice barely carrying across the wooden box. His thumb traced the line of her wrist, steady and deliberate. The trapdoor above slammed open against the wall with the force of a gunshot. "Radoslav!" Zofia hissed from the top of the ladder, her voice sharp with panic. She dropped down three rungs, her eyes wild in the gloom. "The Grand Prelate's retinue just entered the street. Elzbieta has invoked the Inquisitorial Seal—she isn't waiting for the council. She is bringing the holy oil to your duchy tonight!"
