In this riveting true crime thriller, New York Times bestselling author Johann Hari hunts the serial killers stalking Las Vegas--and finds a larger story about the disintegration of the American Dream. This is the strangest serial killer story ever told: Hidden in the tunnels beneath the Las Vegas Strip is a secret city--one that homeless people have built, and the police are afraid to enter. When Johann Hari began to explore it in 2011, he discovered something strange: The tunnel-dwellers kept disappearing, or turning up dead. Both Hari and the Vegas police begin to suspect that a serial killer might be preying on the homeless population in and around the tunnels. But even when a suspect was jailed, the murders did not stop. It soon became clear that something even darker was taking place--that Las Vegas had become an incubator for serial and spree killers who target the homeless, and nobody knew why. This mystery would become a fifteen-year obsession for Hari. His quest for the truth led him to investigate a chain of bizarre and tragic events, including the kidnapping of a thirteen-year-old girl, the election of a mayor who befriended one of the worst murderers in American history, and the rise of a cult-like Korean church predicting the end of the world in a nuclear holocaust. Hari gained unique access to the police investigation, the prosecutors, the defense, the families--and, in a shocking final confrontation, he came face to face with the killers themselves. We Die in the Dark is an astonishing page-turner--one that reveals the dark trendlines in the United States that are increasingly spilling over into murder, and shows that serial killers are not what we think they are.
