One night during a June heat wave, a car crashes into a tree in central Dublin and bursts into flames. The police assume the driver's death was either an accident or a suicide, but Quirke's examination of the body leads him to believe otherwise. Then his daughter Phoebe gets a mysterious visit from an acquaintance: the woman, who admits to being pregnant, says she fears for her life, though she won't say why. When the woman later disappears, Phoebe asks her father for help, and Quirke in turn seeks the assistance of his old friend Inspector Hackett. Before long the two men find themselves untangling a twisted string of events that takes them deep into a shadowy world where one of the city's most powerful men uses the cover of politics and religion to make obscene profits.
