The first body, discovered by cattle drovers, lies bloody at the bottom of a ridge. For nine months, over hundreds of miles of Kentucky and Tennessee countryside, the terror unfolds. Drawing from her new book, Kingdom of Devils: A Tale of Murder in the Shadow of the American Revolution (2026), Katherine Grandjean investigates the historical meanings of the Harps’ infamous spree, revealing the dark side of the young United States’ independence. While the American Revolution was liberating to some, it was also deeply destabilizing, politically and socially, to others. Grandjean unspools the mystery of what sent the Harps reeling and exposes the hidden, violent legacies of the revolutionary era.
