Morden i Sandhamn plot
Sandhamn is a Swedish island off the coast of Stockholm. It is an idyllic holiday island where it is quiet outside the summer season. Only about 120 people live here, but as the midsummer night approaches, the population multiplies due to the large numbers of holidaymakers and sailors who come here to enjoy the sun and the sea. When a murder is committed, Inspector Thomas Andreasson springs into action. He is divorced after the death of his first child. He is aided in his investigation by childhood friend Nora Linde, who owns a summer house on Sandhamn. Her private life is not easy for her either, because she has marital problems with her husband Henrik, a doctor who has little patience for his wife's ambitions for a career of her own.
