I read these mystery/thrillers set in foreign lands as much for the insight into another culture as for the mystery, so this novel was a disappointment when I learned almost nothing about North Korea. It's an authoritarian system. Great. I didn't even get much of a sense of "asia-ness" about it. As for the actual mystery - nobody actually seemed to care about the "Corpse in the Koryo" hotel, and it's solution was a throwaway at the very end.
