“I most certainly do not. I told Prince Rodolfo somebody else would have to do that disagreeable job.” She pursed her lips at Petra’s baffled expression. She said testily, “Kristof makes things disappear. That is his talent. Of course, it has its limits like anything else. He can only make living things disappear, though I assure you that is quite enough. Let’s say he wanted to make you disappear. He would need to make a brush that included a strand of your hair, and paint mixed with your blood. Then he would paint your portrait. Since people don’t exactly leave their blood lying around, there are only a certain number of poor, foolish people he can paint. Thank heavens.”

Petra thought about Kristof, about his unlocked door and sweet manner. She thought about how the prince had tricked her father into thinking he was a friend. If you would like to know how easy it is to overlook evil, to see it for something else, Petra could tell you: it is the easiest thing in the world.

SERVANTS AT SALAMANDER CASTLE were allowed one day off a month. Petra was eagerly looking forward to her first free day when, unexpectedly, it came early. She got a sick day, of sorts. But she was not the one who was ill. Iris had an acid attack.

One morning, Petra pushed open the door to the Dye Works and was greeted with a strange sight. Footprints had melted into the stone floor. The puddlelike holes trailed from the bright side of the room and disappeared into the dark half, where one part of the velvet curtain was burned away.

“Iris?” Petra called. “Are you there? Are you all right?”

“Of course I am!” Iris was hiding behind the remainder of the black curtain—naked, Petra guessed. “I just got upset.”

“But you always get upset.”

“This is different!” Petra heard the sniff of somebody whose handkerchief had disintegrated. “When I get very, very angry or depressed my skin churns out acid like your grandmother’s best cow makes milk.”

Petra decided not to mention that she had neither a grandmother nor a cow. She was concerned about Iris, because it probably wasn’t so entertaining to be na**d and trapped in an adamantine chair behind a curtain. “Well, are you angry or sad?” It didn’t seem too difficult to tell the answer to the question, since Petra had heard more than one snotty sniffle. But she thought she would ask.

“I’m both!” Iris pounded the arm of her chair. “The moment I give that hedgehog Hortensia her hair dye, what do you think happens? I’ll tell you: twenty-six of her closest friends and enemies march in here wanting the same exact color! Twenty-six! Do they stop to think that they’re going to look like a row of identical, dotty daffodils? No! Why oh why does the court become a playground for flirtation between the rich, magicless, and brainless?”

Petra knew the answer as well as Iris did: there was no place else for them to go. When aristocratic children failed the Academy exams, they packed up their fripperies and went straight to Salamander Castle. There they usually tried to make one another miserable, arrange a suitable marriage, amuse themselves with drinking and dancing, or some combination of the above. If Iris’s attitude was anything to judge by, the Academy-trained researchers of the Thinkers’ Wing had little patience for the young courtiers.

“And I am no closer to inventing a new primary color! It needs to be ready in advance of the celebrations, so that we can use the color to dye the prince’s robes. I promised Prince Rodolfo that the color would be ready soon. Why was I so confident?” This last word was a wail of shame.

Astrophil was unsympathetic. What a prima donna. You would think that the entire world revolves around her invention.

Petra saw his point, but felt sorry for Iris. She understood how easy it is to put so much emotion into a project. “Iris, don’t worry. You still have several weeks before the prince’s birthday. You have time.”

Iris sniffed.

“Can’t you just turn your magic off? Go into acid retirement, maybe?”

“Retire!” Iris snorted. “You can’t just wish away your magic. Anyway, my gift has its compensations.” “Like what?”

“Well, for example, if I get emotional enough and touch a patch of phosphorus, I can make a green so bright it would make your eyes sing.”

“It doesn’t seem worth it. What’s the point of a magical talent that makes your skin ooze acid every time you get angry or sad?”

Iris chuckled. Slowly, at first. Then she laughed as if Petra had just said something hilarious. “Oh, you little lamb!” she wheezed. “Clearly no one has ever attacked you. No one has ever done you an ounce of harm in your life. Am I right?” Her laughter died away and was replaced by an earnest voice. “I do hope that I will continue to be right. Now, get out of my laboratory. I’m giving you the day off.”

That was Iris. She had never bothered to learn Petra’s name. She was cranky, self-absorbed, and arrogant. But she could surprise you. Petra heard protectiveness in the woman’s voice, and she suddenly realized that Iris liked her.

The Menagerie

PETRA PASSED BY her locked wooden chest and then made her way to the stables. She found Neel outside the building, trundling a wheelbarrow full of manure. His expression was as sour as the smell surrounding him.

“What are you doing?” Petra made a face.

“What do you think? The only job I could get was mucking out the stables.” He set down the wheelbarrow.

“But I haven’t seen you anywhere in the castle. I’ve been looking for you at dinner.”

“Where Sadie would be? My sis? Who’s not supposed to know I’m here?” Neel shot Petra a hard, irritable glance.

She bit her lip. Of course Neel wouldn’t have been at dinner. Petra felt embarrassed, and this made her belligerent. “Well, Sadie doesn’t go into the men’s dormitory.” Petra’s voice rose. “I’ve been sneaking around the entrance to that room every night, and you’re never there.”

Neel laughed mirthlessly. “You think the rest of the servants would let Gypsies eat with them? Sleep with them? Not on your life. Tabor and I are only good enough to clean up after the horses. Even if I weren’t keeping clear of Sadie, I’m not the right color to break bread at a gadje table, or sleep on a gadje bed. Tabor and I go back home when the working day’s over. Come on, don’t tell me you’re surprised.”

This was the second time in one hour that someone had treated Petra as if she didn’t understand the way the world worked. Annoyed, she frowned and was about to say something when Neel cut in: “I don’t need your pity.”

“I wasn’t going to give it!” she flared. “You’d probably rather spend the night with your family anyway!”

“Well, yeah! But that’s hardly the point, is it?” He shook his head and picked up the wheelbarrow again, walking away from Petra. For a moment, she stood there. Then she spun on her heel and began striding away.

Petra, you are overreacting, said Astrophil.

I am not! I’m tired of getting nowhere. All I do is work day in and day out in the bowels of the castle. And when I’m finally free, I go to see somebody who’s supposed to be my friend. And the only thing he does is yell at me!

Are you sure you did not yell at him first?

Petra slowed her pace. But she defended herself. He was being impossible! He said he would help, and he hasn’t even bothered trying to get a message to me. And he’s been working here the whole time!

Exactly. He has been working here the whole time.

Petra stopped in her tracks.

Do you think, the spider continued, that he would be shoveling horse manure if he did not really want to be part of the plan?

Petra hated it when Astrophil was right—which was very often. But she turned around and ran to catch up with Neel. The boy glanced at her and looked away. He continued to push the wheelbarrow until they had reached a corner of the grounds reserved for drying manure in the sun to sell later as fertilizer.

“At least it’s not hot,” Petra ventured. She had been stuck inside the castle for so long that she had not realized that the weather had truly changed. The air was chilly enough to make the tip of her nose cold. A brisk wind blew across the dusty yard. “The stink would be really bad in summer. And the flies.”

Neel tipped the horse droppings into a large pile. “So I’m supposed to be grateful, then?”

Maybe you can find a cheerier subject to discuss than manure, Astrophil suggested to Petra.

Petra pulled her father’s notebook from under her shirt, where she had tucked it into the waistband of her skirt. “Neel, I want you to do something for me. This is one of the most valuable things I own. It can’t be found, but I don’t have a good place to keep it. Would you hide it for me, please? There’s no one else I can trust.” She held out the book.

He wiped his hands on his trousers and took it. He flipped through the pages. “It’s just a bunch of signs and drawings.”

“It’s my father’s. It’s about the clock. I don’t really understand what it all means, but it could be important. I don’t think the prince knows it exists, but if he did”—Petra took a deep breath —“he’d probably do just about anything to have it.”

Petra knew she was taking a risk. If what her father said was true, if the prince truly didn’t know how to use the clock, then the book could indeed be very valuable to him. She couldn’t leave it in her locked chest. She was sure that the servants’ lockers were regularly searched by the housekeeper. If Harold Listek found the notebook, he might not think it was important. But if he did …

Petra hoped Neel would hide it. The tricky thing was, now that Neel knew the book might be important to the prince, he might try to sell it for the price of several horses.

Neel looked at her. She could read the same thought in his tawny eyes. She almost snatched the book out of his hands. He glanced away, peering at the pages again. He lifted a brow. “Huh.”

“What?” she snapped. She should never have shown him the book. What was the point of trying to win the trust of someone you cannot trust?

“Your da understands the idea of zero.”

“What?” She looked over his shoulder to see which pages had caught his interest. They showed strings of equations. Oh, those pages, she thought. “What’s ‘zero’? Is that a Romany word?”

“That is zero.” He pointed to a symbol shaped like the letter O. “You know your numbers, right? One, two, three, four—”

“Yes.” She glared.

“Well, zero comes before one.”

That had to be wrong. “Nothing comes before one.”

“That’s kind of the point.”

He ruffled his hair and turned a page. Petra balled her fists in frustration.

Astrophil spoke up, addressing Neel. “Are you trying to say that zero operates as a placeholder for calculations? That it represents nothingness?”

Neel nodded. “But the gadje don’t use it. It’s stupid that you don’t. You can’t do knotty math without it.”

“Do you understand what the equations mean?” Astrophil asked.

“No, but I can guess that Petra’s da was trying to measure energy, not blocks of wood.”

Petra was speechless. It was a good thing Astrophil wanted to do all of the talking.

“How do you know this?” the spider asked Neel.

He shrugged. “Zero comes from the same place as my people. Even if it hadn’t, we would have picked it up along the way. It’s a neat idea. The best thing about wandering everywhere is that you can choose what you like of a place and take it with you, like almonds off the tree.”

“How is it possible that the Roma are interested in complex mathematics and yet your people cannot read?”

“It’s not that we can’t. Why should we read?”

“Well, to pass along information. To record your history.”

“Information should be shared by people, not things. These pages are just dead trees.” He frowned at the spider. “Any history worth having should be alive.”

Petra held up an irritable hand. “Are you two talking philosophy? Because if I wanted to listen to that I would be sitting on a splintery bench in the Okno schoolhouse. Neel, will you hide my father’s book or not?”

The boy weighed the book in his hand. Then he put it under his shirt. “Yeah, sure. I’ll hang on to it for you.” Then he seemed to guess her wish to change the subject. “You seen the menagerie?”

“No. What’s that?”

“The prince’s animal collection. Come on, Petali.” He tugged at her sleeve. They walked across the grounds until they reached a locked door. Neel held his hand a few inches from the keyhole and twisted his fingers. The door clicked, and he pushed it open.

The garden was a paradise of green geometric shapes. There was an elaborate maze and enormous flowers that Petra had never before seen in her life. Some of the blossoms were as large as her head. She was astonished that so many flowers were growing. It was, after all, already October. Butterflies fluttered like scraps of colored paper. A tiny, needle-beaked bird with wings that were a constant blur ducked in and out of the flowers.

“That’s a hummingbird,” said Neel. “Looks like a flying blue-green jewel, doesn’t it? Hummingbirds don’t live in Bohemia. And you’d never see all these flowers blooming about in one spot at the same time. Guess the prince had em magicked.”

He led her to a series of large cages. Monkeys screeched and clambered upside down at the top of one cage, swinging themselves back and forth. In another cage, they saw a bewildering creature with shiny fur, webbed feet, and a duck’s bill. “It lays eggs, just like a spider,” Astrophil informed them. This just made the animal seem even more bizarre.
