The last few shadow-fish were being worn away to wriggling threads, and then they vanished, grown so thin they couldn’t be seen. He slowed the chant, and paused it. The fire banked a little, an inexpressible relief. He demanded, grimly, “Enough?”

I opened my mouth to say yes, to say please. “No,” I whispered, horribly afraid now. I could feel the faint quicksilver trace of the shadows still inside me. If we stopped now, they would curl up deep, hiding in my veins and my belly. They would take root and grow and grow and grow, until they strangled all the rest of me.

He nodded once. He held out his hand, murmured a word, and another flask appeared. I shuddered; he had to help me tip a swallow into my open mouth. I choked it down, and he took up the chant again. The fire rose in me again, endless, blinding, burning.

After three more swallows, each one stoking the fire back up to full height, I was almost sure. I forced myself to one more after that, to be certain, and then finally, almost sobbing, I said, “Enough. It’s enough.” But then he took me by surprise and forced another swallow on me. As I spluttered, he put his hand over my mouth and nose, and used a different chant, one that didn’t burn but closed my lungs. For five horrible heartbeats I couldn’t breathe at all, clawing at him and drowning in the open air: it was worse than everything else had been. I was staring at him, seeing his dark eyes fixed on me, implacable and searching. They began to swallow up all the world; my sight was closing, my hands were going weak; then at last he stopped and my frantic lungs swelled open like a bellows dragging in a rush of air. I yelled with it, a furious wordless shout, and shoved him away from me so he went sprawling back across the floor.

He twisted up, managing to keep the flask from spilling, and we glared at each other, equally angry. “Of all the extraordinary stupidities I have ever seen you perform,” he snarled at me.

“You could have told me!” I shouted, arms wrapped around my body, still shaking with the horror of it. “I stood all the rest, I could have stood that, too—”

“Not if you were corrupted,” he said flatly, breaking in. “If you were taken deep, you would have tried to evade it, if I’d told you.”

“Then you would have known, anyway!” I said, and he pressed his mouth hard, into a thin line, and looked away from me with an odd stiffness.

“Yes,” he said shortly. “I would have known.”

And then—would have had to kill me. He would have had to slay me while I pleaded, maybe; while I begged him and pretended to be—perhaps even thought myself, as I had—untainted. I fell silent, catching my breath in slow, measured, deep drafts. “And am I—am I clean?” I asked finally, dreading the answer.

“Yes,” he said. “No corruption could have hidden from that last spell. If we’d done it sooner, it would have killed you. The shadows would have had to steal the breath from your blood to live.”

I sagged limply in on myself and covered my face. He pulled himself to his feet and stoppered the flask. He murmured, “Vanastalem,” moving his hands, and stepped over to me: he thrust out a neatly folded cloak, heavy silk-lined velvet, deep green, embroidered in gold. I looked at it blankly, and stared up at him, and only when he looked away from me with an annoyed, stiff expression did I realize that the last glowing embers were dying beneath my skin, and I was still naked.

Then I staggered up to my feet abruptly, holding the cloak clutched against me, forgotten. “Kasia,” I said urgently, and turned towards her where she lay beneath the cage.

He didn’t say anything. I looked back at him desperately. “Go and dress,” he said finally. “There’s no urgency.”

He’d seized me the instant I came into the tower: he hadn’t let a moment pass. “There must be a way,” I said. “There has to be a way. They’d only just taken her—she couldn’t have been in the tree for long.”

“What?” he said sharply, and listened with his brows drawing as I spilled out the horror of the clearing, of the tree. I tried to tell him about the dreadful weight of the Wood, watching me; the feeling of being hunted. I stumbled over it all: words didn’t seem enough. But his face grew more dark, until at last I finished with that last staggering rush out into the clean snow.

“You’ve been inexpressibly lucky,” he said finally. “And inexpressibly mad, although in your case the two seem to be the same thing. No one has gone into the Wood as deep as you and come out whole: not since—” He halted, and I somehow knew without his saying her name that it was Jaga: that Jaga had walked in the Wood, and come out again. He saw my realization, and glared at me. “And at the time,” he said, icily, “she was a hundred years old, and so steeped in magic that black toadstools would spring up where she walked. And even she wasn’t stupid enough to start a great working in the middle of the place, although I will grant that in this case, it’s the only thing that saved you.” He shook his head. “I should have chained you to the wall as soon as that peasant woman came here to weep on your shoulder, I suppose.”

“Wensa,” I said, my dull, exhausted mind latching on to one thing. “I have to go tell Wensa.” I looked towards the hallway, but he cut in.

“Tell her what?” he said.

“That Kasia’s alive,” I said. “That she’s out of the Wood—”

“And that she will surely have to die?” he said, brutally.

Instinctively I backed towards Kasia, putting myself between them, holding my hands up—futile, if he had meant to overcome me, but he shook his head. “Stop mantling at me like a rooster,” he said, more weary than irritated: the tone made my chest clench in dismay. “The last thing we need is any further demonstrations that you’ll go to fool’s lengths for her sake. You can keep her alive as long as we can keep her restrained. But you’ll find it a mercy by the end.”

I did tell Wensa, when she woke a little later that morning. She clutched my hands, wild-eyed. “Let me see her,” she demanded, but that much, the Dragon had flatly forbidden.

“No,” he said. “You can torment yourself if you want to; that’s as far as I’ll go. Make that woman no false promises, and don’t let her come anywhere near. If you’ll take my advice, you’ll tell her the girl is dead, and let her get on with her life.”
