Händelser vid vatten

Annie and Mia try to settle in the collective, but Annie is tormented by thoughts of the murders. When Birger is drawn into the murder investigation, it affects both marriages and friendships. In 1991, Annie is found dead in Lobberån, but the cause of death puzzles Birger and Mia.

The police show up at the Stjärnberg collective and interrogate Dan. Annie suspects that Dan is lying about Midsummer Night. Birger discovers that Barbro is not telling the truth about her Midsummer Eve either. In Norway, Johan gets to see newspaper articles about the tent murders. 18 years later, Birger contacts ex-police officer Åke, who still has the investigative material from the murder. It turns out that the police may have missed a possible perpetrator.

Petrus confirms Annie's suspicions that Dan was away from the commune on the midsummer night. Johan is picked up by his mother in Norway, but the family does not want him to come home to Sweden. In 1991 Birger and Johan go to Helsinki to find Ylja, who they suspect has things to tell about Midsummer Eve 1973.

It is winter and the heavily pregnant Annie decides to leave the Stjärnberg collective together with Mia. In 1991, Birger and Johan visit Dan in Stockholm, who tells them where he was on Midsummer Night 1973, and the shadows of the past can finally be dispelled.
