I rose to my feet, ready to leave, although I had nowhere to go. I couldn’t walk back down the stairs. The thought made me dizzy. Neither could I go back up. Lithodora would have returned to the village by now. They would be searching the stairs for me with torches. I was surprised I hadn’t heard them already.

The tin bird turned its head to look at me as I swayed on my heels, and blinked, the metal shutters of its eyes snapping closed, then popping open again. It let out a rusty cheep. So did I, startled by its sudden movement. I had thought it a toy, inanimate. It watched me steadily and I stared back. I had, as a child, always had an interest in ingenious mechanical objects, clockwork people who ran out of their hiding places at the stroke of noon, the woodcutter to chop wood, the maiden to dance a round. The boy followed my gaze, and smiled, then opened the cage and reached in for it. The bird leaped lightly onto his finger.

“It sings the most beautiful song,” he said. “It finds a master, a shoulder it likes to perch on, and it sings for this person all the rest of its days. The trick to making it sing for you is to tell a lie. The bigger the better. Feed it a lie, and it will sing you the most marvelous little tune. People love to hear its song. They love it so much, they don’t even care they’re being lied to. He’s yours if you want him.”

“I don’t want anything from you,” I said, but when I said it, the bird began to whistle: the sweetest, softest melody, as good a sound as the laughter of a pretty girl, or your mother calling you to dinner. The song sounded a bit like something played on a music box, and I imagined a studded cylinder turning inside it, banging the teeth of a silver comb. I shivered to hear it. In this place, on these stairs, I had never imagined I could hear something so right.

He laughed and waved his hand at me. The bird’s wings snapped from the side of its body, like knives leaping from sheaths, and it glided up and lit on my shoulder.

“You see,” said the boy on the stairs. “It likes you.”

“I can’t pay,” I said, my voice rough and strange.

“You’ve already paid,” said the boy.

Then he turned his head and looked down the stairs and seemed to listen. I heard a wind rising. It made a low, soughing moan as it came up through the channel of the staircase, a deep and lonely and restless cry. The boy looked back at me. “Now go. I hear my father coming. The awful old goat.”
