Unseen by Mari Jungstedt

It's summertime on the Swedish isle of Gotland and fears are raised when Helena Hillerstrom and her dog are found murdered near the shore. DS Anders Knutas and his colleagues are surprised by the brutal nature of the crime and look into Helena's life for a possible suspect. When another woman is killed, even more pressure is put on the police because of the large influx of tourists onto the island. Knutas is also trying to find out if there's any connection between the women. Meanwhile, journalist Johan Berg of Swedish National Television has been sent to Gotland from Stockholm to report on the women's deaths. While there, he becomes interested in Helena's best friend, Emma Winarve, even though she's married. As in Unspoken, the second book in the series (Unseen is the first), Jungstedt gives the reader the points of view of Knutas, Johan, and Emma, along with an interesting mystery. Unseen also has a sense of place for several locations on the island of Gotland.
