Laird Hunt has written what is really three stories wrapped around each other. The first is something that really happened: A famous lynching in Marion, Indiana in the summer of 1930. The second is the story of the song, “Strange Fruit,” which was inspired by that lynching. And the third is a new novel, which begins on that terrible day. It’s called “The Evening Road.” In this piece, Hunt tells us how he came to write it.
