Cato Kwong is back. Back in Boom Town and back on a real case-- the unsolved mystery of a missing 15-year-old girl. But it's midsummer in the city of millionaires and it's not just the heat that stinks. A pig corpse, peppered with nails, is uncovered in a shallow grave and a body, with its throat cut, turns up in the local nightclub. As a series of blunders by Cato's colleague brings the squad under intense scrutiny, Cato's own sympathy for a suspect threatens to derail his case and his career.
