A good policeman

On an island in Sweden, a man investigating the mysterious events that hit his father in the sulphurous past.
The plot is complex but well conducted and credible to the end, and it is almost impossible to guess the fall of the novel.
The author added a spooky side to the story, but without falling into pure science fiction. The novel is drawer with destinies in an interesting behind closed doors. All combine to make this book a good novel.
