In The Spirit of Crazy Horse.

A work of narrative nonfiction, Peter Matthiessen’s In the Spirit of Crazy Horse examines the 1975 killing of two FBI agents on the Pine Ridge Reservation and the subsequent prosecution of Leonard Peltier. Blending investigative journalism with historical analysis, Matthiessen situates the event within a longer history of U.S. colonial policy, treaty violations, and systemic repression of Indigenous political movements, particularly the American Indian Movement. The book interrogates the legal and evidentiary foundations of the Peltier case while foregrounding the broader climate of violence and surveillance that characterized federal–Native relations in the 1970s. "A superb piece of investigative writing which at times sounds like a first-class mystery story - unfortunately too true. In the Spirit of Crazy Horse shines light into some of the darkest, murkiest corners of our judiciary system. I couldn't put it down" (Richard Erdoes).
