I went silently down the stone steps. This door would open onto the cell level. My hands shook as I felt for the keyhole in the dark. There were four keys. The third one turned the mechanism with a sharp “clack.” I froze, listening. Nothing. No. A voice, muffled by distance or a closed door, inside the building. A man’s voice. I opened the door, eased through, and shut it behind me. I was in a stone-flagged hallway, one I remembered too well. A single lantern burned on a hook, yielding dim illumination. The cell doors that opened off it were staggered. Each had a small barred window at eye level, and a slot for a meal tray at the bottom. I went past the cell that had been mine without looking inside it. She wouldn’t be here. Spink had said she was in a “punishment” cell, one without a window.

I passed six cells and came to a second door. It, too, was locked. Luck gave me the correct key the first time. I turned it in the lock, then I pressed my ear to the door. The man’s voice was louder, a droning monotone. There was no window in the door. Stronger light spilled in a puddle from under it. I took a breath, unsheathed my sword, and opened the door.

Another hall, this one lit by a succession of lanterns on wall hooks.

At the end of that hall, a door was ajar. Light and the man’s voice were spilling out of it. I listened a moment. Was he singing? No, reciting something, over and over. I moved stealthily closer. I was halfway down the hallway before I recognized it.

It was the same night prayer my mother had taught me. The man was repeating it over and over in a horrid, breathless way that spoke of fear beyond measure. It made the hair stand up on the back of my neck. Swift and silent as a plains cat, I padded down the hall and then peered around the edge of the door.

It took me a few moments to make sense of what I saw there. There was a small guardroom with a table and two chairs, and beyond it, a locked door. One guard sat at the table, his head slumped forward on his chest. The other sat stiffly in his chair, laced up to attention. He was the one speaking, saying his hopeless, helpless little prayer over and over. Every surface in the room, the walls, the floor, the tabletop, the guards themselves were netted over with pale white root. The only parts of the room innocent of the spreading filaments were the iron hinges and reinforcements of the door. As I watched, a network of rhizomes worked its way up over the slumped guard, as if spinning him a shroud of white lace. It sank into him as it worked, tattooing his clothing to his flesh as it dug into him as ivy digs into a stone wall. He was definitely dead.

But the other guard was as emphatically alive. His arms were bound to his sides with roots and his legs were clenched tight together with them. I wondered how they could have both been overcome so quickly and so thoroughly, and then didn’t want to know if the roots could truly grow that fast. The man looking at me gave a sudden squeal and then said, “Oh, god, oh, god, oh, god!” In horror, I watched as the roots began to thread themselves into his ears. He squealed again, and then abruptly the noise stopped. The guard suddenly spoke in a very calm voice. “He says he does what you should have done before you left the town that night. And she says, she says, she says she wants all of you, she always wanted all of you, that she wept when the old god stole parts of you away. Come to the tree outside, she says, and she will gently take you in.”

He spoke conversationally, in such a rational voice that I answered him the same way. “I don’t want to come to you, Lisana. I want Amzil. And as much of my own life as is left to me.”

The man did not speak again. He made a gargling sound and then shook his head back and forth in a sudden, vigorous negative. His mouth opened, and a wet wad of bloody root spilled from it to cascade down his chest.

And from the other side of the locked door, I heard a woman give a muffled scream.

“Amzil!” I cried, but I doubt that she heard me. In the instant of silence that followed my horrified shout, I heard a small voice behind me.

“Mummy?” Kara asked in a terrified whisper. I whirled. She stood behind me, staring in horror at the root-wrapped men. She wore only a short white nightshirt, and she was barefoot. Where had she come from?

“Get back!” I bellowed at her. “Don’t let the roots touch you, Kara. Get back!” I swung my gaze back to the small room. “Get out of my way, Lisana. I don’t want to hurt you, but I’m coming through!” I touched my bared sword to the stone floor. I pushed it into the room, and the tiny tender roots that webbed the floor parted and writhed back from the deadly touch of the iron. A stouter one resisted, but then parted with a snap and curled back on itself. Panting fear, I trod the narrow path my blade created. The small room seemed to stretch a mile. I reached the door and had to free my right hand to try a key. It didn’t work.
