Letters from the Grave is a compilation of letters from outlaws of the Old west, writing a letter back to their killer, enemies, and foes. In these letters we tell a mystery, and pose the question, if these outlaws were alive and could write a letter to anyone, what would they say. Shotgun Bo rivers captures the Old West in these fantastic letters from the grave, leading us into a mystery of the past, writing letters to Pat Garret, William Pinkerton, Jack McCall, Jesse James, and more.
