The Darkness by Ragnar Jonasson

At 64, DI Hulda Hermannsdottir will be retiring at the end of the year from the Reykjavik police department. When her boss, Magnus, tells her that she actually has to retire right now, she is stunned, because her job means everything to her and she doesn't know what she will do with all the time she will have. Hulda is is able to get Magnus to agree that she can work two more weeks on a cold case of her choosing. Hulda knows just the case she will work on--the death of Elena, an asylum seeker from Russia who died less than two years ago. As she begins to investigate, Hulda realizes how much a colleague botched the original investigation, and there is little doubt that Elena was murdered. Will Hulda be able to wrap up the case in the time she's been given? The Darkness is the first book in the Hulda series. The series is actually a trilogy that will go backwards in time, with the next book taking place twenty-five years before this one. I really enjoyed The Darkness and look forward to reading the other books.
