Bäckström plot
Police inspector Evert Bäckström is by no means a model of a righteous citizen, let alone a police inspector. He is lazy, corrupt and cynical and constantly brags about solving 99% of his cases. He is a thorn in the side of the young Commissioner Annika Carlsson and the new District Attorney, Hanna Hwass. Then the ten-year-old boy Edvin reports to him with a human skull that he has found on the uninhabited island Ofärdsön.
