Christmas shoppers stop to hear a Salvation Army concert on a crowded Oslo street. A gunshot cuts through the music and the bitter cold: one of the singers falls dead, shot in the head at point-blank range. Harry has little to work with: no suspect, no weapon, and no motive. As the search closes in, the killer becomes increasingly desperate. Harry encounters true darkness: among the homeless junkies and Salvationists, eagerly awaiting a savior to deliver them from misery whether he brings new life or immediate death.
