In a small North Carolina town in 1976, three siblings are shot to death. That's the mystery at the center of De'Shawn Charles Winslow's new book, Decent People – and it's one the segregated town's white police officers aren't paying much attention to. In today's episode, Winslow tells NPR's Scott Simon about the heroine who takes it upon herself to solve the case, and why - the author feels a need to paint a nuanced portrait of even the antagonists in his books.
