During the "simmer dim" when the sun never goes down in Shetland, Jimmy Perez investigates the deaths of two people in the far north of the island. One is an unknown man and the other the most famous Shetlander in the world. I loved this book. I liked it better than the first one (Raven Black) as the main character was a bit more developed and it just had a different feel. Maybe the simmer dim affected me too as Raven Black took place in the winter.
