Blue blood

In an idyllic neighbourhood of Copenhagen, a young woman, Susanne Hansson, is discovered in her apartment bound and gagged, the victim of an extraordinarily brutal rape attack. Detective Inspector Louise Rick soon learns that Susanne met the rapist on a popular online dating site, something Susanne shamefully tries to hide. Events quickly spiral out of control as a horrified Louise realises that the rapist is using the website to target specific women for future attacks.
