The Devil on Eighty-five is a crime novel from the ultimate battleground of America's absurd drug wars: the Arizona-Mexico border. When a Tohono O'odham cowboy is accused of murdering his wife, Manuel Aguilar follows a trail running out the west end of the reservation to Ajo, Arizona-and to Arizona State Route 85, a smuggling corridor where guns and money go south and drugs and migrants go north. Evil loves darkness on highway 85 and the desert itself is the deadliest player in the game.
