Hugo Contreras, the protagonist of Raul Palma's new novel, is a babaláwo; he can cleanse evil spirits. Except he doesn't really believe in the whole thing. So when he's able to strike up a deal with a debt collector – get rid of the ghosts in his house in exchange for a clean slate – he assumes he can mostly fake it. In today's episode, Palma joins NPR's Scott Simon to discuss A Haunting in Hialeah Gardens, and how the concept of debt – not just financial, but personal, too – stirs up a lot of trauma for Hugo.
