This is a mature mystery that took me awhile to really get into. However, once you understand how the author is approaching the story, you realize how well written it is. The author has a marvelous method of describing the people and the various places where the actions take place. Being set in many locals in Western Europe has added to the richness of the story. Besides the cold case mystery itself, there are very interesting backgrounds of each of the characters and their relationships with one another. A good read!
