This mystery is about the Norwegian role in WWII. Some folks fought with the Germans against the Russians, and then were returned to Norway and tried as traitors. This is all fascinating stuff, but the number of characters that are included and the switching back and forth in perspective and time (from the Russian front and WWII to a recent present) left me dizzy. I finished the book, and I was glad that I did b/c now I know who done it, but it overwhelmed me with some history and some current Neo Nazi activities in Norway.
