Reddit reviews North Korea under Communism: Report of an Envoy to Paradise

There's an interesting book by Erik Cornell, the first Swedish ambassador to North Korea about his times there. He retells some of the more strange things, my favourite is when the embassy basement suddenly filled with smoke and no one could understand why. Turned out that tunnels connected the embassy basements to some kind of listening post and they guys manning it had been less than careful when warming their lunches and caused a small fire. The government denied the whole thing.
