The Bat book by Jo Nesbø

Before Harry took on the neo-Nazi gangs of Oslo, before he met Rakel, before The Snowman tried to take everything he held dear, he went to Australia. Harry Hole is sent to Sydney to investigate the murder of Inger Holter, a young Norwegian girl, who was working in a bar. Initially sidelined as an outsider, Harry becomes central to the Australian police investigation when they start to notice a number of unsolved rape and murder cases around the country. The victims were usually young blondes. Inger had a number of admirers, each with his own share of secrets, but there is no obvious suspect, and the pattern of the other crimes seems impossible to crack. Then a circus performer is brutally murdered followed by yet another young woman. Harry is in a race against time to stop highly intelligent killer, who is bent on total destruction.
