Celia takes the captured ring to the Red Lantern Market and proves the same contract paid one blade to kill Elian...
At Red Lantern Market, a man sold bottled screams beside a woman weighing funeral buttons, and nobody looked twice at Celia until she put a Crown-marked ring on the poison broker's scale.
The scale dipped. The broker stopped smiling.
Damien Salt wore a plum velvet coat over a shirt stained at both cuffs, and his white hair was tied with a ribbon the color of old bruises. Behind him, shelves climbed to the tent roof: amber vials, black vials, tin boxes stamped with spider legs, paper twists of powdered sleep. The air tasted of cloves and metal.
"Pretty," Damien said. "Not yours."
"It came from a man dying under my roof."
"Then it is very much not yours."
Vesper stood at Celia's left shoulder, pale from the crossbow wound but upright. Mara hovered near a display of forged mourning permits, fingers twitching with professional interest. Niko waited outside the tent because Damien had looked at his cut arm and named three prices for it.
Celia kept her bandaged hand flat on the counter. "I need an antidote ledger for a clear capsule carried by a Crown-ringed blade. I also need to know who bought the dose."
Damien's gaze moved over her black dress, the singed hem, the missing veil. "Widows usually begin with flowers."
"I had flowers. They were poisoned."
That earned a flash of teeth. "You are Orrin Thorn's widow."
"You sold to the person who killed him?"
"Careful. I sell many things. Certainty costs extra."
Vesper leaned forward. "So does breathing through your own throat."
Damien did not lean back. "Black Veil threats in my tent? How nostalgic. I thought you were all busy being mismanaged by a woman with chapel ash on her cuffs."
Celia set her remaining wedding pearl beside the ring. It looked small under the red lantern light. It had been Orrin's grandmother's. Celia had worn it against her wrist the day she married him because the setting was too old-fashioned for a gown and Orrin had said old-fashioned luck still counted.
"Start with certainty," she said.
Damien picked up the pearl, held it to his teeth, then slipped it into a drawer. "Clear capsule. Bitter finish? Foam pink at the lips?"
"Yes."
"Glass-lily distillate. Expensive. Fast enough to silence, slow enough to ask one question first if you are rude and lucky."
Mara placed the dead assassin's glove on the counter. The torn cloth still carried a smear of foam. "Batch mark?"
Damien's eyes flicked to her. "Mara Quill. Still making dead men sign birthday cards?"
"Only for clients with poor handwriting."
He opened a ledger bound in cracked yellow leather. Unlike the blood-ink contract, these pages did not burn. They smelled worse. He turned them with a silver hook instead of his fingers.
"Glass-lily, clear capsule, Crown ring issue." Damien tapped a line. "Sold yesterday to a courier using a dead-drop tag from Black Veil."
Vesper's hand went to her knife.
Celia caught one word. "From?"
"Do not bruise the language, widow. I said from."
Mara bent over the ledger. "A Black Veil tag paid for poison used by a man wearing Crown issue."
"And?" Damien said. "The city is full of people dressing for work."
Celia looked at the line below. Another payment, same contract number, different hand. "What is this?"
Damien tried to close the ledger. Celia drove Orrin's iron key through the page and into the counter. The wood split. Every conversation near the tent seemed to pause.
Vesper murmured, "That was not subtle."
"I am tired of subtle men trying to kill women in clinics."
Damien looked at the key in his counter, then at Celia. The amusement thinned. "That page is worth more than your remaining jewelry."
"Then it should have guarded itself."
Mara read aloud before he could stop her. "Three hundred crowns for Sister Elian dead. One hundred crowns for the contract blade dead before reporting completion."
Vesper went very still.
Celia felt the market tilt around that second line. "They paid one assassin to kill Elian and another poison to kill the assassin."
"Not uncommon when buyers dislike loose mouths," Damien said.
"It is uncommon when the buyer uses our tag," Vesper said.
The word our landed like a knife laid flat. Not loyalty, not yet. But possession.
Damien sighed and reached beneath the counter. Vesper had a blade at his wrist before his fingers closed around whatever waited there.
"Antidote ledger," he said mildly. "Unless you prefer your captured man dead and your safehouse full of unanswered questions."
Celia nodded. Vesper let him move. Damien produced a narrow slate covered in chalk columns: dose, counterdose, buyer scent, delivery mark. Mara copied it with a speed that made Celia's eyes ache.
At the far side of the market, bells rang twice. Red lanterns dimmed across the stalls.
Damien swore. "You were followed."
Niko ducked into the tent. "Not followed. Surrounded creatively."
Three market guards in lacquered masks shoved through the crowd, and behind them walked the chain-wrist assassin from the cellar. He had not voted for Celia with any joy. Now he wore a new red cord at his throat.
Vesper's voice dropped. "Bran."
Bran smiled. "Widow. Quartermaster. Hand over the ring and the page. Guild property should not wander."
Celia pulled the key from Damien's counter. The torn ledger page came with it, pinned and fluttering.
"Is he yours?" she asked Vesper.
"He was."
Bran drew the chain from his wrist. A hook flashed at the end. Market customers backed away with the smooth discipline of people used to not being stabbed by mistake.
Damien ducked behind his counter. "No blood on the velvet."
Mara threw a mourning permit into the nearest lantern. Green smoke bloomed. Niko kicked over a jar of pickled eel eyes. They rolled across the floor like wet marbles. Bran lunged, slipped, and Vesper met him with her wounded side hidden and her good knife low.
Celia did not try to fight him. She ran at the scale.
The ring still sat in one brass pan. She struck the other pan with Orrin's key. The scale arm snapped upward, flinging the Crown ring into the smoky air. Bran's eyes followed it despite himself.
Vesper cut the red cord from his throat.
Not his throat. The cord.
Attached to it was a dead-drop tag stamped with the same contract number as Damien's ledger.
Bran froze.
"You sold your vote quickly," Vesper said.
"I sold nothing," Bran snarled. "I was ordered."
"By whom?" Celia asked.
He looked at her with sudden fear, the first honest expression she had seen from him. "If I say it, the ink takes my heart."
Mara caught the falling ring in her handkerchief. Her face had gone pale. "Celia."
"What?"
Mara held the ring beside the red cord tag, then beside a folded paper from inside her sleeve: Orrin's final reform brief, the one Celia had found hidden behind the chapel compartment. The paymaster mark on the brief was small, almost decorative, a crowned three-bar seal at the margin.
It matched.
Damien, still crouched behind velvet, whispered, "Now that certainty is free, I would like everyone to leave my tent."
Bran backed away into the smoke. Vesper let him go because Celia shook her head once. A frightened traitor could carry panic to better places than a corpse could.
Celia wrapped the torn poison ledger around the Crown ring.
Orrin's final case had not brushed against the murder contract.
It had signed the payment mark.
