on herself. Behind Sextus, YOU LIED TO US stretched out in vast array.
“Step one,” she said, singsong, “preserve the soul, with intellect and memory intact. Step two, analyse it—understand its structure, its shape. Step three, remove and absorb it: take it into yourself without consuming it in the process.”
“Oh, fuck,” said Harrow, very quietly. She had moved back to Gideon’s side now, slipping her journal back into her pocket. “The megatheorem.”
“Step four, fix it in place so it can’t deteriorate. That’s the part I wasn’t sure of, but I found the method here, in this very room. Step five, incorporate it: find a way to make the soul part of yourself without being overwhelmed. Step six: consume the flesh. Not the whole thing, a drop of blood will do to ground you. Step seven is reconstruction—making spirit and flesh work together the way they used to, in the new body. And then for the last step you hook up the cables and get the power flowing. You’ll find that one a walk in the park, Eighth, I suspect it was your House’s contribution.”
Palamedes said: “Princess. You never had any keys. You never saw any of these rooms, except this one.”
“Like I said,” said Ianthe, “I am very, very good, and moreover I’ve got common sense. If you face the challenge rooms, you don’t need the study notes—not if you’re the best necromancer the Third House ever produced. Aren’t I, Corona? Baby, stop crying, you’re going to get such a headache.”
“I came to the same conclusion you did,” said Palamedes, but his voice was cold and inflexible. “I discarded it as ghastly. Ghastly, and obvious.”
“Ghastly and obvious are my middle names,” said the pale twin. “Sextus, you sweet Sixth prude. Use that big, muscular brain of yours. I’m not talking about the deep calculus. Ten thousand years ago there were sixteen acolytes of the King Undying, and then there were eight. Who were the cavaliers to the Lyctor faithful? Where did they go?”
Palamedes opened his mouth as though to answer this question; but he had bumped against something on the back wall, and had gone still. Gideon had never known him to be still. He was a creature of sudden movement and twitchy fingers. Camilla was watching him with obvious suspicion; one of his thumbs was tracing the edge of a black-painted letter, but the rest of his body was rigid. He looked as though someone had turned his power switch off.
But Silas was saying—
“None of this explains why you have killed Naberius Tern.”
Ianthe cocked her head to one side, drunkenly, to take him in. The violet of her eyes was dried-up flowers; her mouth was the colour and softness of rocks.
“Then you weren’t listening. I haven’t killed Naberius Tern. I ate Naberius Tern,” she said, indifferently. “I put a sword through his heart to pin his soul in place. Then I took it into my body. I’ve robbed Death itself … I have drunk up the substance of his immortal soul. And now I will burn him and burn him and burn him, and he will never really die. I have absorbed Naberius Tern … I am more than the sum of his half, and mine.”
Her head hung close to her chest again. She gave a hiccup that sounded a little bit like a sob, and a little bit like a laugh. As she did she appeared blurry and indistinct before them—rocking out of her edges, somehow, unreal. Gideon’s skin had already been crawling, but now it was trying to sprint.
Palamedes said, though he sounded as though he were ten thousand years away, “Princess, whatever you think you’ve done, you haven’t done it.”
“Oh, haven’t I?” said Ianthe.
She rose to stand, but Gideon did not see her move. Ianthe came back to solidity all at once, more real now than anything around her. The room faded into insignificance. She glowed from the inside out, like she had eaten a fistful of lightbulbs. “Do you really deny it, even now?” she said. “God, it makes so much sense. Even the rapiers—light swords, light enough to be held by an amateur … a necromancer. Each challenge—fusing, controlling, binding, utilising—utilising whom? Did you notice that none of those challenges could be completed by yourself? No, you didn’t, and yet that was the biggest red flag. I had to reverse-engineer the whole thing, just from looking at it … all alone.”
Silas sounded quite normal now when he turned and addressed the monotonously crying girl by
