The Redeemer - Jo Nesbo
             Series

I actually enjoyed this Harry Hole book!  Either I am finally getting used to Mr. Nesbo's writing style or the notes I took at the beginning help me not get so lost.

In "The Redeemer" a hit man kills the wrong man.  Uh, oh!!!   That is never good!!!!   So we need to help Harry find this hit man, find out who hired him, why they hired him and who is the real target .  All the time, hoping Harry will stay sober,  yes folks,  Harry is sober.  But will he fall off the wagon??   Always a worry when dealing with Harry!!

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 Hole—the Oslo Police Department’s best investigator and worst civil servant—has little to work with: no suspect, no weapon, and no motive. But Harry’s troubles will multiply. As the search closes in, the killer becomes increasingly desperate, and Harry’s chase takes him to the most forbidden corners of the former Yugoslavia
