Näcken, (c) 1882 Ernst Josephson
Too old to believe in Santa, too old to fear forest shadows, too old to sleep when fiddle music scraped against frost-limned windows, an ancient melody whispering of the thrust of men with women, Tjuven stumbled off-path. He didn't need moonlight; the music was enough.
He hadn't expected the creature, a violin beneath its chin, reclining in the brook. Hungry eyes made his loins warm, uncomfortable.
Cold wind blew against his face, wet with tree-scraped blood that dripped thrice. The creature shivered, waited, but Tjuven was too old to believe in Näcks and too young for baptism to protect him.
