Inspector Harry Hole tracks a Norwegian serial killer in this installment of Jo Nesbo's New York Times bestselling series. Now a Major Motion Picture starring Michael Fassbender. One night, after the first snowfall of the year, a boy named Jonas wakes up and discovers that his mother has disappeared. Only one trace of her remains: a pink scarf, his Christmas gift to her, now worn by the snowman that inexplicably appeared in their yard earlier that day. Inspector Harry Hole suspects a link between the missing woman and a suspicious letter he's received. The case deepens when a pattern emerges: over the past decade, eleven women have vanished--all on the day of the first snow. But this is a killer who makes his own rules . . . and he'll break his pattern just to keep the game interesting, as he draws Harry ever closer into his twisted web. With brilliantly realized characters and hair-raising suspense, international bestselling author Jo Nesbo presents his most chilling case yet--one that will test Harry Hole to the very limits of his sanity.
