“I could trust you with gavriels, could I?” he asked.

“Of course you could. What kind of question is that?”

She felt his appraisal, as if he were mentally reviewing every wish she’d ever made.

Blue hair: frivolous.

Erasing pimples: vain.

Wishing off the light switch so she didn’t have to get out of bed: lazy.

He said, “Your necklace is looking quite short. Have you had a busy day?”

Her hand flew to cover it. Too late. “Why do you have to notice everything?” No doubt the old devil somehow knew exactly what she’d used these scuppies for and was adding it to his mental list:

Making ex-boyfriend’s cranny itch: vindictive.

“Such pettiness is beneath you, Karou.”

“He deserved it,” she replied, forgetting her earlier shame. Like Zuzana had said, bad behavior should be punished. She added, “Besides, it’s not like you ask your traders what they’re going to use their wishes for, and I’m sure they do a hell of a lot worse than make people itch.”

“I expect you to be better than them,” Brimstone said simply.

“Are you suggesting that I’m not?”

The tooth-traders who came to the shop were, with few exceptions, about the worst specimens humanity had to offer. Though Brimstone did have a small coterie of longtime associates who did not turn Karou’s stomach—such as the retired diamond dealer who had on a number of occasions posed as her grandmother to enroll her in schools—mostly they were a stinking, soul-dead lot with crescents of gore under their fingernails. They killed and maimed. They carried pliers in their pockets for extracting the teeth of the dead—and sometimes the living. Karou loathed them, and she was certainly better than them.

Brimstone said, “Prove that you are, by using wishes for good.”

Nettled, she asked, “Who are you to talk about good, anyway?” She gestured to the necklace clutched in his huge clawed hands. Crocodile teeth—those would be from the Somali. Also wolf fangs, horse molars, and hematite beads. “I wonder how many animals died in the world today because of you. Not to mention people.”

She heard Issa suck in a surprised breath, and she knew she should shut up, but her mouth kept moving. “No, really. You do business with killers, and you don’t even have to see the corpses they leave behind. You lurk in here like a troll—”

“Karou,” Brimstone said.

“But I’ve seen them, piles of dead creatures with bloody mouths. Those girls with their bloody mouths; I’ll never forget as long as I live. What’s it all for? What do you do with these teeth? If you would just tell me, maybe I could understand. There must be a reason—”

“Karou,” Brimstone said again. He did not say “shut up.” He didn’t have to. His voice conveyed it clearly enough, on top of which he rose suddenly from his chair.

Karou shut up.

Sometimes, maybe most of the time, she forgot to see Brimstone. He was so familiar that when she looked at him she saw not a beast but the creature who, for reasons unknown, had raised her from a baby, and not without tenderness. But he could still strike her speechless at times, such as when he used that tone of voice. It slithered like a hiss to the core of her consciousness and opened her eyes to the full, fearsome truth of him.

Brimstone was a monster.

If he and Issa, Twiga, and Yasri were to stray from the shop, that’s what humans would call them: monsters. Demons, maybe, or devils. They called themselves chimaera.

Brimstone’s arms and massive torso were the only human parts of him, though the tough flesh that covered them was more hide than skin. His square pectorals were riven with ancient scar tissue, one nipple entirely obliterated by it, and his shoulders and back were etched in more scars: a network of puckered white cross-hatchings. Below the waist he became elsething. His haunches, covered in faded, off-gold fur, rippled with leonine muscle, but instead of the padded paws of a lion, they tapered to wicked, clawed feet that could have been either raptor or lizard—or perhaps, Karou fancied, dragon.

And then there was his head. Roughly that of a ram, it wasn’t furred, but fleshed in the same tough brown hide as the rest of him. It gave way to scales around his flat ovine nose and reptilian eyes, and giant, yellowed ram horns spiraled on either side of his face.

He wore a set of jeweler’s lenses on a chain, and their dark gold rims were the only ornament on his person, if you didn’t count the other thing he wore around his neck, which had no sparkle to catch the eye. It was just an old wishbone, sitting in the hollow of his throat. Karou didn’t know why he wore it, only that she was forbidden to touch it, which, of course, had always made her long to do so. When she was a baby and he used to rock her on his knee, she would make little lightning grabs for it, but Brimstone was always faster. Karou had never succeeded in laying so much as a fingertip to it.

Now that she was grown she showed more decorum, but she still sometimes found herself itching to reach for the thing. Not now, though. Cowed by Brimstone’s abrupt rising, she felt her rebelliousness subside. Taking a step back, she asked in a small voice, “So, um, what about this urgent errand? Where do you need me to go?”

He tossed her a case filled with colorful banknotes that turned out to be euros. A lot of euros.

“Paris,” said Brimstone. “Have fun.”

T HE A NGEL OF E XTINCTION

Fun?

“Oh, yes,” Karou muttered to herself later that night as she dragged three hundred pounds of illegal elephant ivory down the steps of the Paris Metro. “This is just so much fun.”

When she’d left Brimstone’s shop, Issa had let her out through the same door by which she’d entered, but when she stepped onto the street she was not back in Prague. She was in Paris, just like that.

No matter how many times she went through the portal, the thrill never wore off. It opened onto dozens of cities, and Karou had been to them all, on errands like this one and sometimes for pleasure. Brimstone let her go out and draw anywhere in the world where there wasn’t a war, and when she had a craving for mangoes he opened the door to India, on the condition that she bring some back for him, too. She had even wheedled her way into shopping expeditions to exotic bazaars, and right here, to the Paris flea markets, to furnish her flat.

Wherever she went, when the door closed behind her, its connection to the shop was severed. Whatever magic was at work, it existed in that other place—Elsewhere, as she thought of it—and could not be conjured from this side. No one would ever force his way into the shop. One would only succeed in breaking through an earthly door that didn’t lead where he hoped to go.

Even Karou was dependent on the whim of Brimstone to admit her. Sometimes he didn’t, however much she knocked, though he had never yet stranded her on the far side of an errand, and she hoped he never would.

This errand turned out to be a black-market auction in a warehouse on the outskirts of Paris. Karou had attended several such, and they were always the same. Cash only, of course, and attended by sundry underworld types like exiled dictators and crime lords with pretensions to culture. The auction items were a mixed salad of stolen museum pieces—a Chagall drawing, the dried uvula of some beheaded saint, a matched set of tusks from a mature African bull elephant.
