The Redeemer — Jo Nesbo

A 14-year old girl is raped at one of the Salvation Army summer camps. Twelve years later, at a Christmas concert in a square in Oslo, a Salvation Army soldier is executed by a man in the crowd. A press photographer has caught a suspect on one of the photos of the concert. Beate Lønn, the identification expert, is confused by how the face can change from one photo to the next. Inspector Harry Hole's search for the faceless man takes place on the seamy side of the city, among those who seek eternal â€" or just momentary â€" redemption. And the gunman has not yet completed his mission.
