Baltimore Jack was dead. In a place where even the speediest travel slowly, the word spread up and down the length of the Appalachian Trail from Georgia to Maine in a matter of hours. It was May 4, 2016, and one of the most beloved, brilliant, and exasperating antiheroes in the history of long-distance walking was gone.

He was 57, and it was the beginning of his 21st year on the trail. Over that time, he had become a sort of everywhere-at-once presence, bandages wrapped around his battered knees, relying on snack cakes, lasagna, Jim Beam, cigarettes, and the kindness of others to survive. It was a kindness he usually returned.
