THE NIGHT WILL BE LONG

In a remote stretch of southwestern Colombia, Bogota-based journalist Julieta Lezama investigates an ultraviolent confrontation that officials pretend never happened.

Before mysteriously disappearing, an orphaned 14-year-old boy who witnessed the clash tells the 40-ish, trash-talking Julieta how the confrontation ended with a black-attired figure emerging from a bazooka-ed Hummer and escaping in a helicopter. Everyone else in town claims they didn't see or hear anything. All evidence of the confrontation is cleared away. With her assistant, Johana, a veteran of the FARC guerrilla group, Julieta determines that a simmering Mafia-like conflict between a Pentecostal church and an evangelical one had something to do with the roadside drama. The story leads Julieta to French Guiana and Brazil and intense one-on-ones with the churches' corrupt pastors—who, for all their dark edges, win her over with their charisma. Each of them gets to tell his anguished story in long, italicized sections that touch on the "perverse republic" that is Colombia. "When a person screams into the darkness, what reply is possible?" one of them asks. For all that, the book is lifted by its cutting humor, which takes on a dreamy, almost surreal quality. The deeper Julieta gets into the case, the more she drinks, happily aware of what she's doing. For the prosecutor she's working with, the more bodies pile up, the giddier he gets in urging her on. Gamboa can go so deep into a character, such as a pastor obsessed with gold, that he loses the thread of the main narrative. But the book never loses the spark of originality.

An absorbing—at times almost too absorbing—mystery by a notable Colombian author.
