Kaiser and Jeremy are joined this week by Mara Hvistendahl, Pulitzer Prize-nominated author and long-standing resident of Shanghai, to discuss her two main works. Along with discussing the twists and turns of her murder novel, And the City Swallowed Them, we also touch upon law enforcement in China, the global modeling industry, the parallel lives of ex-pats and migrant workers in big Chinese cities, and the different philosophical approaches to punishment. Also, we look into sex-ratio imbalances around the world and its diverse adverse social repercussions, the topic Mara explores in Unnatural Selection.
