"Olivia R\u00f6nning is sure that Jackie Berglund is behind the attack and is trying to recover from it. At the same time Nils Wendt is found, who has been missing since 1987. Where has he been all these years and why has he shown up right now?"

"Olivia contacts a child who was witness to the beach murder. From him she gets a hair slide with a few hairs on it. If there is DNA left on it, perhaps it could be the key to the murder mystery. The police finally breathe some life into Wendt\u2019s mobile and see who he was last talking to. Linn Magnusson now realises that she must find the original recording of the conversation that could destroy her life."

The pieces begin to fall into place, now they have identified the person who had the earring and are just waiting for a crucial DNA analysis. But how does the murder at Nordkoster fit together with the murder of Nils Wendt? And what is the motive?"
