Viet Thanh Nguyen discusses his new novel, “The Committed,” the follow-up to his Pulitzer-winning “The Sympathizer,” and the second entry in a planned trilogy. It brings Nguyen’s storytelling further into the philosophy of refugees, feminism, communism, anti-communism and more—the terror of both the American war in Vietnam and the French presence in Vietnam, along with the Vietnamese presence in America andFrance. This is duality enacted as a writing method; this is a union between theory and fiction. A novel of ideas and politics and history and theory, but also a crime novel. A novel you’re not born knowing how to read, and you might have to reread it, this is exciting contemporary literature.
