Jo nesbo - nemesis

Captured on closed-circuit television: A man walks into an Oslo bank, puts a gun to a cashier's head, and tells her to count to twenty-five. When he doesn't get his money fast enough, he pulls the trigger. The young woman dies—and two million Norwegian kroner disappear without a trace. After a drunken evening with former girlfriend Anna Bethsen, Police Detective Harry Hole wakes up at home with a headache, no cell phone, and no memory of the past twelve hours. The same day, Anna is found shot dead in her bedroom, making Hole a prime suspect in the investigation led by his hated adversary, Tom Waaler.
