Nemesis

I very much enjoyed Nemesis by Jo Nesbo (even though I read it out of order). It is the second part of a trilogy - The Redbreast, Nemesis and The Devil's Star. They can be read independently, but there is a thread running through them which is finally resolved in the third book, so I recommend you read them in order. Harry Hole investigates the apparent suicide of an ex-girlfriend - was she murdered? The other investigation relates to an armed bank robbery where a female teller is murdered. This turns out not to be a simple investigation either. 4/5
