New York City, late 1860s. When young Chris Harmony learns that members of his family may have been involved in the illegal pre-Civil War slave trade, taking slaves from Africa to Cuba, he is appalled. Determined to learn the truth, he begins an investigation that takes him into a dingy waterfront saloon, musty old maritime records that yield startling secrets, and elegant brownstone parlors that may have been furnished by the trade. Since those once involved dread exposure, he meets denials and evasions, then threats, and a key witness is murdered. Chris has vivid fantasies of the suffering slaves on the ships and their savage revolts. How could seemingly respectable people be involved in so abhorrent a trade, and how did they avoid exposure? And what price must Chris pay to learn the painful truth and proclaim it?
