The silent, snow-covered streets of Oslo are a perfect scene of Christmas tranquillity. But over the tolling of bells for the last Sunday of Advent, a black note sounds. A boy's ­body washes up near the shoreline of the city's Aker Bridge. His corpse is bloated by the water, almost unrecognisable. Nobody has even bothered to report him missing.
One week later, the bishop of Bergen is found stabbed to death on a deserted street. Eva Karin Lysgaard is a popular public figure, a sixty-two year-old grandmother: why was she on a lone errand in the deserted city, on the night before Christmas?
Johanne Vik, criminal researcher and police profiler, is called in to untangle the motivation behind the bishop's murder. But with her husband at the head of this increasingly high-profile investigation, Vik's association with the case is under intense scrutiny. And why does Lysgaard's shocking death lead her towards the sad death of an unknown boy?
