I tie the horse to one of the black metal rings driven into the stone wall of the tower. She whickers nervously, her tail tucked hard against her body. I touch her muzzle in what I hope is a reassuring way.

“I won’t be long, and then we can get out of here,” I tell her, wishing I’d asked the groom for her name.

I don’t feel so differently from the horse as I knock on the heavy wooden door.

A large, hairy creature opens it. He’s wearing beautifully wrought plate armor, blond fur sticking out from any gaps. He’s obviously a soldier, which used to mean he would treat me well, for Madoc’s sake, but now might mean just the opposite.

“I am Jude Duarte, seneschal to the High King,” I tell him. “Here on the crown’s business. Let me in.”

He steps aside, pulling the door open, and I enter the dim antechamber of the Tower of Forgetting. My mortal eyes adjust slowly and poorly to the lack of light. I do not have the faerie ability to see in near darkness. At least three other guards are there, but I perceive them more as shapes than anything else.

“You’re here to see Prince Balekin, one supposes,” comes a voice from the back.

It is eerie not to be able to see the speaker clearly, but I pretend the discomfort away and nod. “Take me to him.”

“Vulciber,” the voice says. “You take her.”

The Tower of Forgetting is so named because it exists as a place to put Folk when a monarch wants them struck from the Court’s memory. Most criminals are punished with clever curses, quests, or some other form of capricious faerie judgment. To wind up here, one has to have really pissed off someone important.

The guards are mostly soldiers for whom such a bleak and lonely location suits their temperament—or those whose commanders intend them to learn humility from the position. As I look over at the shadowy figures, it’s hard to guess which sort they are.

Vulciber comes toward me, and I recognize the hairy soldier who opened the door. He looks to be at least part troll, heavy-browed and long-limbed.

“Lead on,” I say.

He gives me a hard look in return. I am not sure what he dislikes about me—my mortality, my position, my intruding on his evening. I don’t ask. I just follow him down stone stairs into the wet, mineral-scented darkness. The bloom of soil is heavy in the air, and there is a rotten, mushroomy odor I cannot place.

I stop when the dark grows too deep and I fear I am going to stumble. “Light the lamps,” I say.

Vulciber moves in close, his breath on my face, carrying with it the scent of wet leaves. “And if I will not?”

A thin knife comes easily into my hand, slipping down out of a sleeve holster. I press the point against his side, just under the ribs. “Best you don’t find out.”

“But you can’t see,” he insists, as though I have played some kind of dirty trick on him by not being as intimidated as he’d hoped.

“Maybe I just prefer a little more light,” I say, trying to keep my voice even, though my heart is beating wildly, my palms starting to sweat. If we have to fight on the stairs, I better strike fast and true, because I’ll probably have only that one shot.

Vulciber moves away from me and my knife. I hear his heavy footfalls on the steps and start counting in case I have to follow blind. But then a torch flares to life, emitting green fire.

“Well?” he demands. “Are you coming?”

The stairs pass several cells, some empty and some whose occupants sit far enough from the bars that the torchlight does not illuminate them. None do I recognize until the last.

Prince Balekin’s black hair is held by a circlet, a reminder of his royalty. Despite being imprisoned, he barely looks discomfited. Three rugs cover the damp stone of the floor. He sits in a carved armchair, watching me with hooded, owl-bright eyes. A golden samovar rests on a small, elegant table. Balekin turns a handle, and steaming, fragrant tea spills into fragile porcelain. The scent of it makes me think of seaweed.

But no matter how elegant he appears, he is still in the Tower of Forgetting, a few ruddy moths alighting on the wall above him. When he spilled the old High King’s blood, the droplets turned into moths, which fluttered through the air for a few stunning moments before seeming to die. I thought they were all gone, but it seems that a few follow him still, a reminder of his sins.

“Our Lady Jude of the Court of Shadows,” he says, as though he believes that will charm me. “May I offer you a cup?”

There is a movement in one of the other cells. I consider what his tea parties are like when I’m not around.

I’m not pleased he’s aware of the Court of Shadows or my association with them, but I can’t be entirely surprised, either—Prince Dain, our spymaster and employer, was Balekin’s brother. And if Balekin knew about the Court of Shadows, he probably recognized one of them as they stole the Blood Crown and got it into my brother’s hands so he could place it on Cardan’s head.

Balekin has good reason to not be entirely pleased to see me.

“I must regretfully refuse tea,” I say. “I won’t be here long. You sent the High King some correspondence. Something about a deal? A bargain? I am here on his behalf to hear whatever it is you wish to say to him.”

His smile seems to twist in on itself, to grow ugly. “You think me diminished,” Balekin says. “But I am still a prince of Faerie, even here. Vulciber, won’t you take my brother’s seneschal and give her a smack in her pretty, little face?”

The strike comes openhanded, faster than I would have guessed, the sound of the slap shockingly loud as his palm connects with my skin. It leaves my cheek stinging and me furious.

My knife is back in my right hand, its twin in my left.

Vulciber wears an eager expression.

My pride urges me to fight, but he’s bigger than me and in a space familiar to him. This would be no mere sparring contest. Still, the urge to best him, the urge to wipe the expression from his smug face, is overwhelming.

Almost overwhelming. Pride is for knights, I remind myself, not for spies.

“My pretty face,” I murmur to Balekin, putting away my knives slowly. I stretch my fingers to touch my cheek. Vulciber hit me hard enough for my own teeth to have cut the inside of my mouth. I spit blood onto the stone floor. “Such flattery. I cheated you out of a crown, so I guess I can allow for some hard feelings. Especially when they come with a compliment. Just don’t try me again.”

Vulciber looks abruptly unsure of himself.

Balekin takes a sip of his tea. “You speak very freely, mortal girl.”

“And why shouldn’t I?” I say. “I speak with the High King’s voice. Do you think he’s interested in coming all the way down here, away from the palace and its pleasures, to treat with the elder brother at whose hands he suffered?”

Prince Balekin leans forward in his chair. “I wonder what you think you mean.”

“And I wonder what message you’d like me to give the High King.”

Balekin regards me—no doubt one of my cheeks must be flushed. He takes another careful sip of tea. “I have heard that for mortals, the feeling of falling in love is very like the feeling of fear. Your heart beats fast. Your senses are heightened. You grow light-headed, maybe even dizzy.” He looks at me. “Is that right? It would explain much about your kind if it’s possible to mistake the two.”

“I’ve never been in love,” I tell him, refusing to be rattled.

“And of course, you can lie,” he says. “I can see why Cardan would find that helpful. Why Dain would have, too. It was clever of him to have brought you into his little gang of misfits. Clever to see that Madoc would spare you. Whatever else you could say about my brother, he was marvelously unsentimental.

“For my part, I barely thought of you at all, and when I did, it was only to goad Cardan with your accomplishments. But you have what Cardan never did: ambition. Had I only seen that, I would have a crown now. But I think you’ve misjudged me, too.”

“Oh?” I know I am not going to like this.

“I won’t give you the message I meant for Cardan. It will come to him another way, and it will come to him soon.”

“Then you waste both our time,” I say, annoyed. I have come all the way here, been hit, and frightened for nothing.

“Ah, time,” he says. “You’re the only one short on that, mortal.” He nods at Vulciber. “You may escort her out.”

“Let’s go,” the guard says, giving me a none-too-gentle shove toward the steps. As I ascend, I glance back at Balekin’s face, severe in the green torchlight. He resembles Cardan too much for my comfort.

I am partway up when a long-fingered hand reaches out from between the bars and grips my ankle. Startled, I slip, scraping my palms and banging my knees as I go sprawling on the stairs. The old stab wound at the center of my left hand throbs suddenly. I barely catch myself before I tumble all the way down the steps.

Beside me is the thin face of a faerie woman. Her tail curls around one of the bars. Short horns sweep back from her brow. “I knew your Eva,” she says to me, eyes glittering in the gloom. “I knew your mother. Knew so many of her little secrets.”

I push myself to my feet and climb the steps as quickly as I can, my heart racing faster than when I thought I was going to have to fight Vulciber in the dark. My breath comes in short, rapid gasps that make my lungs hurt.

At the top of the stairs, I pause to wipe my stinging palms against my doublet and try to get myself under control.

“Ah,” I say to Vulciber when my breathing has calmed a little. “I nearly forgot. The High King gave me a scroll of commands. There are a few changes in how he wishes his brother to be treated. They’re outside in my saddlebags. If you could just follow me—”

Vulciber looks a question at the guard who sent him to guide me to Balekin.

“Go quickly,” the shadowy figure says.

And so Vulciber accompanies me through the great door of the Tower of Forgetting. Illuminated by the moon, the black rocks shine with salt spray, a glittering coating, like that on sugared fruit. I try to focus on the guard and not the sound of my mother’s name, which I haven’t heard in so many years that, for a moment, I didn’t know why it was important to me.
