"Ford County" is a collection of short stories by a man who has sold millions of copies of his legal thrillers in this country alone. John Grisham is still in the prime of his writing life, a devoted baseball fan, a devout Baptist who has done missionary work in Brazil, a rural Southerner who practiced law in a small Mississippi town for nearly a decade at the beginning of his literary career. He's a writer whose paperbacks can be read without embarrassment by businessmen on airplanes, because his work tends to avoid sex or violence and to concentrate on puzzles alone.
