略多。。。Beloved is a novel by the American writer Toni Morrison, published in 1987. Set in 1873 just after the American Civil War (1861–1865), it is based on the story of the African-American slave, Margaret Garner, who escaped slavery in 1856 in Kentucky by fleeing to Ohio, a free state. A posse arrived to retrieve her and her children under the Fugitive Slave Act of 1850, which gave slave owners the right to pursue slaves across state borders. Margaret killed her two-year-old daughter rather than allow her to be recaptured.
Beloved's main character, Sethe, kills her daughter and tries to kill her other three children when a posse arrives in Ohio to return them to Sweet Home, the plantation in Kentucky from which Sethe had recently fled. The daughter, Beloved, returns years later to haunt the house in which she was killed, Sethe's home at 124 Bluestone Road, Cincinnati. The story opens with an introduction to the ghost: "124 was spiteful. Full of a baby's venom."
