'With a few simple strokes on the keyboard, he could see the little people in their everyday lives over satellite. These superstitious and hardly intelligent creatures still believed in pure luck. It gave him a feeling of power when he could observe them. When weather was good he could even see their faces. Maybe this is what gave him the greatest pleasure.' The Gotlandic myth about the White sea-lady has existed ever since Tjelvar lit the fire and the island rose out of the sea. The story is told about a young woman who drowned on her wedding night and who has since tried to lure men down into the underwater streams outside the west coast. The myth is brought up again an early morning just before midsummer, when a nurse is found murdered in the pavilion on the Tempel Hill in the Botanic garden. She is dressed as a bride. Detective Inspector Maria Wern is investigating the case. It turns out to be an uneven struggle where the killer can observe every step the police takes. With an intelligent and a technical know-how which by far exceeds everything they thought possible an evil strategy is laid out. Evil is closer than they think.
