This is an interesting departure from the previous books. The main chief detective, Erlendur, does not appear - he's off east chasing his demons in the mountains - so the book focuses on Elinbor to solve the crime. We learn more about her background and find out that she has her own family issues: the surly teenage son whose blog about his family and life are Elinbor's only connection to what he's doing and thinking. Like all of the previous books there is a deceiving simplicity to the mystery and a spareness to the writing that makes compelling reading. The solution is a surprise and the end leaves the fate of Erlendur, who is alone in the countryside and out of contact, unknown thus setting up the next book. A good read.
