“You can’t do that ever again,” he said.
“I have to,” she said. “I have no idea how to open it from the outside. But it’s not that bad. I cool down soon enough. It’s not like stone or brick—stone burns me, my clothing catches fire. I have to watch to make sure I never brush against stone when I’m hiding.”
In reply he hugged her. “You have no idea what it meant to me, to know I had a sister.”
“And to me,” she said. “He told me never to tell Mother that I knew about you. But you were coming and you would set me free.”
“I will,” he said. “I know how to follow these passages to get through the outside wall.”
“Under it?” she asked.
“The land these houses are built on was raised. It’s not as high now, because the weight of the houses presses it down. So some of the passages may have water in them now—this is the river delta, and water is just below the surface everywhere. But as long as we can breathe, we can make it out of here. One long passage leads to the Library of Nothing.”
“How can you know this? Have you gone into these passages before?”
“No,” said Rigg. “But I’ve seen the paths of the people who’ve used them. I know where they went. That’s what I do—I see their paths, even when they’re hidden behind walls or underground.”
“You have a much more useful gift than mine,” she said.
“Mine didn’t get me into this space. Mine doesn’t allow me to disappear in plain day.”
“Yours doesn’t burn you up when you pass through things.”
“I’m sorry I walked through you that time.”
“It wasn’t bad,” she said. “We were both moving—it means we didn’t occupy the same space for very long. Walls are stationa
ry. I’m the only one moving, and the contact lasts a lot longer.”
He held her hands tightly. “What did you call him? The man I knew as Father?”
“Walker,” she said.
“So he was in this house?”
“Yes,” she said. “I told Mother that one of the scholars had inadvertently helped me understand my gift. But really he came here as a gardener. The gardens still show his touch. Why didn’t you know he was here? Couldn’t you see his path?”
“Father—Walker—he doesn’t make a path. He has no path.”
“How could he manage that?”
“I don’t know if he manages it or simply doesn’t have one. He’s a saint, I think. A hero. He has powers other people don’t have.”
“But when I was invisible, he couldn’t see me, the way you can.”
“I can’t see you, I can only see where you were—the spot you passed through and left behind a moment before. And it isn’t seeing, exactly. I can close my eyes or turn my back and still find your path.”
“He said you were the best of us.”
“Us?”
“All his students.”
“So he told you about others?”
“He said the world has bent itself to make us. These powers run strong in this wallfold, he said. So everything depends on us.”
“What everything?” asked Rigg. “Restoring the monarchy? I don’t really care about that.”
