" Light shone through a large crack in the wall of the maze ahead of us. A slim, slender silhouette cast a shadow against the passage floors. Der Erlkönig. I did not marvel then that I knew the shape of his body as well as my own reflection.
I watched the Goblin King's shadow play his violin, his right arm moving in a smooth, practiced bowing motion. Käthe tried to pull me away, but I did not go with her. I moved closer to the light, and pressed my face to the crack. I had to look, I had to see. I had to watch him play.
The Goblin King's back was turned to me. He wore no fancy coat, no embroidered dressing gown. He was simply dressed in trousers and a fine cambric shirt, so fine I could see the play of muscles in his back.
He played with precision and with considerable skill. The Goblin King was not Josef; he did not have my brother's clarity of emotion or my brother's transcendence. But the Goblin King had his own voice, full of passion, longing, and reverence, and it was unexpectedly... vibrant. Alive.
I could hear the slight fumblings, the stutters and starts in tempo, the accidental jarring note that marked his playing as human, oh so human. This was a man- a young man?- playing a song he liked on the violin. Playing it until it sounded perfect to his imperfect ears. I had stumbled upon something private, something intimate. My cheeks reddened.
"Liesl."
My sister's voice sliced through the sound of the Goblin King's playing like a guillotine, stopping the music mid-phrase. He glanced over his shoulder, and our eyes met.
His mismatched gaze was unguarded, and I felt both ashamed and emboldened. I had seen him unclothed in his bedchamber, but he was even more naked now. Propriety told me I should look away, but I could not, arrested by the sight of his soul bared to me.
We stared at each other through the crack in the wall, unable to move. The air between us changed, like a world before a storm: hushed, quiet, waiting, expectant. "
