On the night of the first snowfall in Oslo, a young boy awakens to find his mother missing and a snowman standing ominously outside—wearing her scarf. Inspector Harry Hole is called in to investigate, and what begins as a disappearance rapidly escalates into a pattern of chilling abductions, each heralded by a snowman. As Hole digs deeper, he uncovers a serial killer's trail woven through cold clues, winter motifs, and the detective’s own psychological burdens.
