On November 20, 1903, Tom Horn was hanged in Cheyenne, Wyoming, for the murder of a fourteen-year-old nester boy. Horn-army scout and interpreter for Generals Willcox, Crook, and Miles in the Apache wars, Pinkerton operative, cattle detective, and "King of Cowboys"-was hanged like a common criminal, many think mistakenly. Regardless of Horn's guilt or innocence, his story, beginning when he was a runaway Missouri farm boy, provides a firsthand look at scout Al Sieber in action, at the military both great and small, at the wily Geronimo, the renegade Natchez, and old Chief Nana of the Apaches.
