In the decades before the U.S. Civil War, slavery was legal in southern states and slave pens and auction blocks were located right in the heart of the nation's capital. In 1841, a free black man from Saratoga, New York, was kidnapped and spent the next 12 years of his life as a slave in the deep South. His ordeal comes to life in a new audiobook production of his account, which was saved from obscurity by a white southern woman. VOA's Greg Flakus has the story from Houston.
