He left the Vipers and Gate Lords as they were, trapped by his plants. If they were not cut loose first, the plants would free them at dawn. Then the new growth would search underground until it found yards, courtyards, and other open spaces to grow.

Briar followed his connection to Evvy into the afternoon light and up onto a roof. Keeping to the upper road, he began to trot, laying his plans as he followed her captors.

Only once did he change course, when he spotted a team of Watchmen in the street below. He climbed halfway down a ladder to the street and waved to get their attention. “I have a message for your mutabir,” he called when they looked up. “Tell him Pahan Briar Moss says if he still wants a look inside the house of Lady Zenadia doa Attaneh, he’ll be able to see anything he wants in a couple of hours. Tell him she’s kidnapped my student, and say I asked, ‘Now will you act?’”

“Mind your manners!” banked a Watchman.

“We’re supposed to believe you’re a pahan?” asked one of them, a woman in the short, sheer, yellow face-veil worn by some nomad tribes to the south.

Briar was done with manners and patience — look where they had gotten him! A seed that had escaped his packets clung damply to his hand. He flicked it out, feeling — rather than seeing — it drop onto the street before the squad. “Believe what you like,” he said. Two cobbles went flying in advance of a stout, woody-trunked grapevine that leaped from the ground.

Briar climbed back up to the rooftop road, too angry to care if they were so vexed that they tried to shoot him full of arrows. They didn’t. He looked down from the roof. Most of the squad had gathered around the vine, caressing its trunk in wonder and awe. Two others raced up the street toward Justice Rock.

Before he moved on, Briar strengthened the vine he’d just planted, stopping its absurd growth in time for it to fit in with the cycle of winter rains to come. If the city didn’t cut it down, it would remind people he’d been there.

The trip to the Jeweled Crescent and Attaneh Road took a long two hours afoot. As he made his way through the city, the sun dropped lower in the west, casting long shadows along the roofs. It was autumn; the days were shorter. Luckily for him, the seeds of his arsenal didn’t require sunlight to do what he asked of them.

His connection to Evvy stretched, then firmed: she had settled. He still felt only anger in the bond, which reassured him. She didn’t seem hurt or frightened. Did she know he was on her trail? He hoped she did.

Finally he reached Crescent Rim, the broad street that was the inner edge of the Jeweled Crescent. Beyond this point there were no rooftop roads. The houses of the Crescent lay smugly behind ten-foot-tall stone walls and guardian spells, protected from the likes of common folk. Even the Crescent Rim shops were proof that things changed here. They offered custom-made jewelry, delicate porcelains, and fragile cloth the rival of anything sold in the Grand Bazaar. Dropping into the street, Briar noted discreet signs that advertised mages and upper servants for hire, pawnbrokers, shoemakers, and healers. He felt watched, but no one tried to stop him.

It was a long trudge to find Attaneh Road, since he hadn’t gone there from this part of Chammur. His tie to Evvy was of little help — it simply passed through buildings he had to go around. At last he reached familiar surroundings, and made the turn into House Attaneh’s personal street. The shadows were deepening, granting him cover as he followed the road’s turns. At last he reached Lady Zenadia’s home.

An alley circled the lady’s house outside the ten-foot wall. Smiling grimly, Briar drew a thick gray packet from an external pocket in his kit. With the opened packet in one hand and his water bottle in the other, Briar walked the circuit of the wall, first laying a thin line of seeds at its base, then wetting them with a trickle of water. He left no breaks in his sowing, placing a steady line across the one-man gates used by the gardeners when they carried out trash, across the tradesman’s gate he’d used on his last visit, and across the bay that ended in the wrought-iron main gate, until he reached his starting point. As the short autumn day began to end, he could see spells in the walls, from the dimmest hint of the oldest ones to the deep silver sheen of the newest. They looked beautiful as they shifted under the wall’s creamy stucco, forming patterns and ripples of magic. Of course, they would be useless now. They kept away thieves and baffled spy or curse magic. Plants were real, common physical things. The magics in the wall were not made to treat plants or green magic as a threat.

This seed mixture was different from that used in the Vipers’ lair. Its plants were those kinds of green life that grew into cracks in stone and looked for a place to cling. They were destructive if left to grow for too long, weakening walls and loosening mortar. Rosethorn and Briar just speeded — and strengthened — what they did naturally.

Briar rubbed his hands together and woke the seeds up. As vines popped out of the ground, he felt through his magic until he grasped a connection stronger than any of the others. It went straight to his shakkan, his storehouse of extra power. The tree was elated to be called on: it often complained that too much magic in its trunk, roots, branches, and needles was not comfortable. The best word to describe the tree when it had not been tapped for a while was “itchy.”

“Let’s scratch your itch,” he said. He drew on that pent-up magic, hurling it into the trees, bushes, and grasses inside the wall. The sheer strength of his power, added to the inability of protective magics to recognize green magic as a threat, meant that the spells on the wall didn’t slow him.
