Nemesis by Jo Nesbo. In this second Harry Hole novel, Harry is caught up in two cases-a bank robbery ending in murder, and the mysterious death of an old girlfriend. Unfortunately, Harry was probably the last person to see the woman alive! As he tries to reconcile his grief for his lost partner, a disturbing period of amnesia, and the pleasures and pains of a new relationship, Harry is once again forced to make his own rules to solve the crimes, much to the dismay of his superiors. These books are like potato chips-you can't read just one! Try them now before they get even more popular, and you'll have to be on the waiting list.
