Call Me Princess by Sara Blaedel

Assistant Detective Louise Rick of the Copenhagen police department is assigned the brutal Susanne Hansson rape case because her superiors feel it's best to have a woman as the lead investigator. Susanne met the rapist in an online dating site and, as Louise delves into the case, it becomes clear that the perpetrator has hidden his tracks well. When he claims another victim--who this time dies as a result of the attack--evidence mounts against him, even though the authorities still don't know his identity. With the help of her colleagues and best friend, reporter Camilla Lind, Louise just might catch him. Call Me Princess is the second book in the Louise Rick series (the first hasn't been translated). I really enjoyed the book, especially its Danish setting since Denmark is underrepresented in Scandavian mysteries. It's similar to Liza Marklund's Red Wolf, but a better read.
