When Stephen King originally wrote The Green Mile as a series of six novellas, he didn't even know how the story would turn out. And it turned out to be of his finest yarns, tapping into what he does best: character-driven storytelling. The setting is the small "death house" of a Southern prison in 1932. The Green Mile is the hall with a floor "the color of tired old limes" that leads to "Old Sparky" (the electric chair). The charming narrator is an old man, a prison guard, looking back on the events decades later.
