Chapter 3 From This Moment

The dark lasted three breaths, and in all three I did not move, because my mother taught me that the first thing to die in a black room is the person who runs.

Then light came back. Not the candles. Him. He stood at the turn of the stair with a flame cupped in his bare palm, cold and white, throwing his shadow huge against the ceiling, and the woman in the mirror was gone and the frost was gone and the long line of grey brides was gone, and there was only me and the spotted glass and my own face staring back, too pale.

"What did you see," he said. It was not a question. He had come back down the stairs without my hearing him.

"Nothing." The lie was out before I decided to tell it. "The candles went out."

He looked at me for a long moment. The white flame turned his eyes to two coins. "The candles go out when the house listens too hard," he said. "It does not do that for nothing. And you are a poor liar, for a Vane."

The name went through me like cold water. "I never told you my name."

Something moved behind his face. He turned and started up the stairs again, and the flame went with him, and I understood I could either follow the light or stand alone in the dark with whatever the mirrors held. I followed.

He took me up and up, past landings where the wallpaper hung in strips, past a corridor sealed with a black iron door that he did not look at and I could not stop looking at, until we reached a set of rooms at the top of the east tower. Warm, almost. A fire that lit itself as we entered. Books. A bed with the curtains drawn back. Mirrors here too, but turned to the wall, every one of them, their faces hidden.

"You will stay here," he said. "Not the rest of the house. Here."

"Why."

He did not answer. He set the cold flame in a dish on the mantel where it burned without wax, and he reached into his coat and drew out a folded paper, soft with age, and he held it as though it might bite him.

"Your uncle's hand," he said. "It came to me a month before the lottery. Asking the keeper of the Gate to confirm that the rite would accept a substitute from the same blood. Asking whether a sister would serve as well as the chosen girl." He looked up. "He knew you would climb that altar before you knew it yourself. He arranged the whole thing so that the wrong sister would be standing on the stone tonight. So that you would."

The fire was warm and I was cold all the way through. "That is not possible. He cried when our mother left. He raised us. He sold his boat to keep Sera in the academy."

"He sold a great deal," the Devil said quietly, "to keep you both alive long enough to be useful."

I wanted to throw the paper in the fire. I wanted to be home in the Mire house with the door bolted and Sera safe and none of this true. Instead I made myself ask the question my mother would have asked. "Useful for what."

He crossed the room to me. I had been braced for it since the altar, the moment a thing like him decided to take what it was owed, and I set my feet and lifted my chin and did not back away. But he did not reach for my throat. He reached for my hand. The cut one. He turned it over, gentle, and looked at the silver mark beneath the dried blood, and his jaw was very still.

"May I," he said. Which no one had ever asked me before about anything.

I did not say yes. I did not say no. I let him.

He laid his thumb over the mark.

It woke. Silver light bloomed up through my skin, brighter than in the square, and this time I felt it answer something in him, a pull, low in my chest, like a hook set behind the breastbone and drawn taut. His breath caught. Mine caught. The light ran up my wrist in a thin line and a matching line surfaced on his own skin where he touched me, silver under the cold pale of him, the two of them reaching toward each other through the place our hands met.

He let go as if I had burned him. The light did not fully fade. It sat under my skin now like a coal.

"That," he said, and his voice was not steady, "is a marriage mark. The true one. It does not appear for a substitute. It does not appear for a girl the curse merely accepts." He looked at me, and for the first time the tiredness in his face cracked all the way open and I saw what was under it, which was fear. "It only answers a true bride. The one the Gate was always reaching for."

"I am a substitute," I said. "I took Sera's place. That is all I am."

"No." He shook his head slowly. "The fog did not take who it was given, Mara. It took who it wanted. It has been waiting for you for a hundred years, and your family knew, and they fed it your sister's name so that you would put yourself in her place and never once ask why it was so easy."

The coal under my skin pulsed in time with my heart.

"If my masters learn what that mark is," he went on, "if the city learns, if your uncle gets what he is reaching for, they will open your throat over the Drowned Gate before the next moon, because a bride who can wear that mark is worth more dead than any seal." He stepped back, and the cold came off him in a wave, and I understood it for what it was now. Not cruelty. A man putting a wall between himself and a thing he had already decided to lose. "I have buried every bride who came before you. I swore I would not learn another one's name."

He went to the door. He stopped with his hand on it, not looking back.

"From this moment, you do not leave my side," he said. "Not for your sister. Not for your uncle. Not for the dead in the glass who are already whispering to you. You stay where I can see you, and you keep that wrist covered, and you do exactly as I say."

"And if I do not?"

"Then you will die the way the others did," he said, "and I find I do not want to watch it twice."

The door closed behind him. The mark glowed on, soft and silver, lighting the dark room from the inside of my own skin, and from somewhere far below in the sleeping house I heard a sound that had no business in an empty hall.

A woman, laughing, very quietly, as though something she had waited a long time for had finally walked through the door.
